Sweet potato is a crop commonly grown in our country, sweet potato yield high adaptability in all parts of our country have different areas of cultivation, sweet potato rich in protein, starch, pectin, cellulose, amino acids, vitamins, and a variety of minerals, nutritional and health value is high. In recent years to carry out sweet potato deep processing project more and more attention from all walks of life, sweet potato deep processing has become a model for the development of green health food, sweet potato deep processing of low investment, low risk, high profit can be extended to the development of the industry chain business opportunities.
Sweet potato deep processing process we take three powder processing as an example:
1, starch part:
Stone-washing-loading-crushing-separation-desanding-fine screening-concentration-dehydration-drying-screening
2, mechanical production of vermicelli part:
Stone-washing-loading-crushing-separation-desanding-fine sieving-sedimentation Powder - mixing - feeding - molding - aging - freezing - loose powder drying (wet starch can be directly deep processing vermicelli, dry starch is also easy to destroy the starch viscosity)
3, anti-handmade vermicelli part:
Stone - cleaning - feeding - crushing - separating - desanding - fining and sieving - concentration - dehydration - drying - sieving - thickening - flour - the second rubbing - hammered powder in the pot - aging - cooling - plate powder hanging rod - freezing Cooling - plate powder hanging rod - frozen - loose powder drying (first of all, it is best to dry starch for processing, after drying, especially high starch sweet potato is difficult to get down a good strip mainly after drying viscosity is poor)
Remarks: 1, the above equipment are in accordance with the equipment of Ruyang Machinery Factory is equipped with the steps of the production process:
2, the three powder broad meaning refers to starch, vermicelli, vermicelli:
The present-day domestic sweet potato starch As well as vermicelli fans market is not empty, but the market is full of all kinds of powder products, but consumers are rarely able to buy in the market to the pure sweet potato vermicelli, fans, and even the younger generation simply do not know whether to eat into the mouth of the sweet potato flour, the domestic market flow of vermicelli, fans, most of the sweet potato, cassava, maize, wheat and other raw materials blended with the processing of the processing of some of the better just poor taste, the more poor-quality noodles, poor strength, viscosity, easy to use, and the most important thing is to make sure that you have the best quality of the vermicelli. Poor strength, sticky, easy to paste the soup, so that the vermicelli market is still driven by profit in the final analysis.
In the country around us will often say that our hometown has a village or a town are doing vermicelli, and very famous, of course, we began to believe that the vermicelli here, because of the time and memory so that we are accustomed to think that this village vermicelli, but because of the interests of the drive of a fake, the family followed the go, so that consumers eat the taste of the time more and more not to the mouth, this time! This so-called noodles famous village encountered production and sales bottlenecks, may encounter two possibilities: 1, closed down a large part of the survival of a portion of the survival of a portion of the workshop may be to the market to run sales, wholesalers want to how much the price of vermicelli I provide how much the price of the vermicelli, small profits and high sales, slowly go to the development. Those who closed down not to do business opportunities may be reopened after seeing the success of the model to learn, the further the development of this place may become a base for the production of powder products, but the base of the production of vermicelli will be sold to other cities, the neighborhood will know that the vermicelli can not be eaten here are fake. 2, may be a part of the producer will be moved away from this village, a different place to continue to produce, but whether to produce a pure finished product, lies in the producer of the vermicelli, but not to produce a pure finished product. Pure finished product, lies in the direction of the producer sales. There are many such villages or townships in the country that were originally known for their taste and quality of finished products, and then recognized for their counterfeiting.
Two, consumer psychology:
Traditional vermicelli, vermicelli, vermicelli and other powder production has a variety of specifications, a variety of thick and thin, wide and narrow styles, all over China have the traditional habit of consuming powder products, but due to different habits and cooking styles, around the vermicelli products, thick and thin, narrow and narrow specifications are not the same, which includes the appearance of the color of vermicelli. South of the Yangtze River, people eat generally to soup, hot pot, stew-based, vermicelli to 1.3, 1.5, 2.0, 2.5mm and other diameters of vermicelli finished products are mainly wide powder generally 08*04, 08*06, 08*10, 08*12mm thickness and width of the powder products are mainly on the powder product preference for the color of the heavy, the general public generally accepted sweet potatoes, plantain taro, peas and so on. The popularly accepted sweet potato, plantain taro, pea and other powder products. North of the Yangtze River, people eat generally fried, stewed, hot pot, cold, pastry traps, etc., vermicelli, vermicelli, fans more than 055, 06, 07, 1.0, 1.2, 1.5, 1.8mm diameter vermicelli finished products are mainly wide powder generally 05 * 4, 05 * 6, 05 * 8, 05 * 10mm thickness and width of the powder products are mainly accepted by the public in general to the sweet potato, Potato, wheat and other products made of flour. China's northeast and northwest of the general public prefer thicker and thicker, lighter color powder products, but the northeast region generally accepted to sweet potatoes, potatoes and other raw materials made of powder products, while the northwest region is easy to accept potatoes, sweet potatoes, corn, grains based on raw materials made of powder products.
The above four divisions are too general, but simplified is indeed a local life often eaten powder products, our country is a population of more than one billion people of the populous country, history will divide us into different cities, in different environments we have this different vernacular cultures, different dietary habits, but we are in the choice of powder products when the public easy to accept is the sweet potato flour, in the above four Division of the area, the different areas of the comprehensive evaluation of the most popular consumer favorite or sweet potato vermicelli.
Sweet potato vermicelli that soft, strong, potato flavor full of taste, so that the old generation of people endless memories, we have heard of those old people said that once the production team under the powder, "put the bottom of the powder pile" is how a flavor. Of course, nowadays vermicelli in all parts of the production and sale of a large number of wholesale traders from all over the country, the market placed a variety of colors eye-catching vermicelli, a variety of thick and thin wide and narrow powder products, but the rural market, the city's food market where exactly to buy pure sweet potato vermicelli, in a word: "difficult", adulteration! These years is probably the word we hear the most.
Powder products is a traditional food, but also an indispensable part of our dishes, for traditional food most people are consumers, we care more about is the quality and taste, not the price, but the demand for powder products more than our personal consumption, but a canteen or a restaurant, etc., the demand for powder products in these places also have a part of the constraints of the market to purchase the quality of vermicelli! The country's market is such that there is a demand for production, I do not exclude for doing mixed starch production of vermicelli business, which is also a kind of is business, but also a way of survival, is this so-called way of survival to make the fake more fake, really less.
The market sales of the so-called "sweet potato vermicelli" price of more than 2.5 yuan -3.5 yuan / kg, 3.5 yuan -6 yuan / kg of such prices, consumers will generally buy 6 yuan / kg of vermicelli, but such a price to buy back is not necessarily pure sweet potato flour, the average consumer for the powder products do not have the ability to identify the true and false, mainly to see how to make the powder products. The ability to identify true and false, mainly to see the color and appearance, but these can be changed according to the production.
Most of the domestic production of vermicelli concentrated in many areas are not sweet potato, small to a village of more than ten households to a township of hundreds of such a scale of at least three to four hundred domestic, in addition to the hottest days of the year, the other time are working overtime in the production of more than a mixture of cassava and maize, low-grade corn starch is mostly vermicelli mixed with pigment, alum, chemical additives, etc., but the circulation of vermicelli from these places of production. Vermicelli produced from these places circulate in all parts of the country, the local people of each production place is not eat these vermicelli, but the market outside of the said may also be produced in this way, a lot of people in the city will drag a friend or go to the countryside to buy farmers to produce vermicelli, the rural generally choose to provide raw materials for sweet potatoes themselves to oversee the production of the equipment owner, in this way the domestic market, a lot of people are looking at the deep processing of sweet potatoes in this The project.
Today there are a variety of large, medium and small-scale sweet potato as raw material from washing to vermicelli molding manufacturers, small and medium-scale production to meet local demand, large enterprises should establish a brand image to go straight to go far mentality to develop. But no matter whether it is a large enterprise or a small also to pure additive-free way to produce the local public favorite powder products, from the acquisition of sweet potatoes to the processing of starch, vermicelli, each link can be nearby the people can see on the spot, so that they trust that these are the pure sweet potato flour, only the local people recognized, in order to have a very good sales market.
Three, the choice of equipment:
1, production overview
Sweet potato deep processing of this introduction to the sweet potato for starch processing, vermicelli, vermicelli, vermicelli processing, mainly because we Ruyang Machinery Factory from 1982 to date, the production of such equipment, has been engaged in the research and development of potatoes starch deep processing equipment research and manufacturing, summarize the experience and the application of equipment through the Long time experience accumulated.
2, notes
Sweet potato starch deep processing equipment selection should be based on the actual local situation, the area of land planting sweet potatoes or the area of possible development of planting, the issue of personal financial capacity, electricity and water should be sufficient. Note that the sweet potato belongs to seasonal processing is generally dug before and after the frost, the processing season can last 30-45 days, small-scale processing is generally about 15-20 days, the reason is that the fresh potatoes used for pulping can not be stored for too long, storage time is too long sweet potato starch saccharification and extraction rate is reduced, and secondly, the sweet potato epidermis is softened, it is not easy to crush. Starch processing and vermicelli processing is divided into two parts, sweet potato processing belongs to seasonal, vermicelli processing should be processed successively after starch processing is completed. The expected envisioned amount of starch storage for vermicelli processing should be completed during the processing period.
For the initial processor in the capital and local sweet potato planting area allows, can be on a set of corresponding large-scale equipment, the whole set is equipped with starch part of the processing to be a large amount of starch to choose a part of the drying, part of the wet storage, drying is used to store the sale of wet storage for their own processing of vermicelli fans. Vermicelli part according to their own sales to choose the size of the equipment or reduce the production cycle. For users without sales to give advice: the first year of processing should focus on the sale of starch, starch sales market is very large, but the sale of starch and vermicelli compared to the profits to be low, but the first year of production of vermicelli sales will not be too considerable, the main purchases may be the nearby farmers or simple packaging gift boxes, do a good job of publicity, vermicelli sales and customers are relying on the time to save up. Integrity-based, quality of survival, people expensive and peaceful, small customers will also bring big sales.
3, equipment selection
Sweet potato processing equipment selection to strong and durable extraction rate is mainly small general farmers with the choice of a set of cleaning and crushing and separation of one piece of equipment, simple and convenient to choose to precipitate to take the powder investment is small, the starch precipitation dug out, the existence of a well-planned storage pool for wet storage and then after the vermicelli processing (every year after the year in March and April before the drying process, the weather gradually warming starch will fermentation). (warming starch will ferment), small and medium-sized plant and large-scale plant must choose to separate the crushing and separation of equipment assembled in an assembly line, so that the production of equipment to reduce the failure rate of the link is smaller, and the starch extraction rate is high, cleaning should be based on the local soil quality of the choice of a few levels of cleaning, cleaning equipment to deal with the soil may be mixed with debris brought about by the production of trouble, the crushing part of the general 3-5 tons of choice of the A level of crushing, 7-8 tons or more can choose 2 levels of crushing, a coarse crushing, a fine crushing, so as to better save power consumption, the separation part of the potato processing generally choose YS-450B cylinder separator group connected to the combination of production, for potato processing this amalgamation of equipment is the best however, the separation of starch slurry needs to be desanded, desanded after the fine filtration of starch, at this time, if you choose to make Vermicelli customers can choose the precipitation method, because the wet starch and sun-dried granular starch potato starch is the best raw material for the production of vermicelli, fine filtration through the cyclone will be washed out of the impurities in the starch, the starch slurry through the dewatering machine dewatering, starch liquid dewatering to the moisture content of 38%-40% starch is automatically fed to the drying tower for drying, drying starch after sieving cooling can be packaged.
The above equipment are Ruyang Machinery Factory equipment as an example, generally a single set of equipment processing capacity of 1t / h, 3-4t / h, 5-6t / h, 7-8t / h, 10t / h, 15t / h, etc. Above the amount of equipment for the processing of sweet potatoes per hour, these equipment can also be used in cassava, potatoes, sweet potatoes, plantain taro, kudzu, plantain root and other starch processing.
Four, industry analysis:
In the processing of powder products in the mastery of technology is the key to the entire production process, the same sweet potato equivalent sweet potato varieties, different producers to produce finished products of color and lustre, the strength of the difference. Below is a general description of the different processing methods in the production of flour products.
1, starch processing part:
We usually see the starch processing is roughly divided into "water", "sour paste noodles", "drying noodles" three kinds of The first kind of clear water surface is also divided into one precipitation to take powder or many times to stir the cylinder to take powder, the processing process of starch through the removal of sand refinement into the precipitation tank, the natural way to precipitate starch, starch precipitation, the discharge of covered slurry water as well as skimming "oil", and many times to stir the cylinder to make starch repeated precipitation, so that the lighter specific gravity of the impurities through the way of precipitation to extract, so as to achieve the starch whitening, and thus to achieve the starch whitening. In order to achieve the purpose of starch whitening in addition to impurities, this way is nowadays potato starch production vermicelli starch processing more ways, the general user in the actual processing of starch through a precipitation directly after taking more powder (vermicelli requires whiteness needs to be precipitated many times, but the general market circulation of sweet potato vermicelli color is heavier). The second acid slurry noodles is in the starch processing starch precipitation stage injected into the acidic slurry, acid slurry can accelerate starch precipitation can also achieve the purpose of starch whitening, acid slurry is also divided into soybean slurry, at this time we will be referred to as: "soybean slurry", also divided into the sweet potato crushed and separated from the slurry after the precipitation fermentation, at this time we will be referred to as: "old slurry", soybean slurry refers to bean starch processing in the refining of acid slurry for potato starch processing, through the soybean slurry processing to enhance the starch whiteness, the old slurry refers to the sweet potato starch processing starch precipitation residual slurry through the yellow, green, black slurry color conversion discernment of the slurry acidity, this old slurry produced by the starch whiteness does not have soybean slurry produced color White, but through its treatment of starch gluten than soybean milk is higher, of course, according to personal mastery. The third type of drying noodles, starch drying general selection of air drying, we usually distinguish starch is natural drying or mechanical drying of the most intuitive method is natural drying is starch granular, mechanical drying is flour, the better sales is the water and sour noodles, drying noodles sales market in general, the reason is that most of the processing of sweet potato starch used in vermicelli fan processing, and drying starch gluten is not as high as the water and sour noodles.
2, vermicelli processing part:
vermicelli processing equipment used in more styles, we temporarily Ruyang Machinery Factory products as an example of vermicelli processing part, is divided into self-cooking type, pot powder two categories.
1, self-cooking type is divided into steam type and puffing machine, steam type vermicelli machine through the water temperature heating, spiral propulsion mode so as to achieve starch cooking molding, can well guarantee the quality of vermicelli fans, by replacing different grinding to determine the specifications of the finished product, can produce pure potato starch, corn, wheat, beans, grains starch, this equipment is by the Ruyang Machinery Factory early research and development of the product, now more advanced to the double helix. Nowadays, it is more advanced into double screw, and it is also the most utilized product by domestic enterprises making Longkou vermicelli. Expansion machine we commonly known as self-cooking machine its working principle is that the spiral and tube wall through high-speed rotation friction generates heat, never cooked starch accumulation molding, this type of equipment is generally applicable to the production of corn, wheat, grains and other starch, it is produced in the production process of heat is not adapted to the low-temperature maturation of the potato starch, pengchemistry machine to make the taste of the powder products are more hard, but the production of rice noodles is a better device.
2, cauldron powder is also known as the so-called consumer mouth handmade powder, basically divided into two kinds of equipment a kind of pumping a kind of not with pumping, pumping a professional point has been divided into the mechanism of powder, transparent appearance, uniform powder, but the finished product taste is poor because of the more hard.
The pot of flour general equipment equipped with: 1, thickening machine, double-cylinder automatic loading and noodle machine, push basin machine, hammer scoop machine. 2, thickening machine, double-cylinder automatic loading and noodle machine, pumping machine, hammer scoop machine. 3, thickening machine, joint and noodle pumping machine, steam kettle, cooling conveyor belt, automatic cutting strips, dialing powder machine. The first equipment to produce vermicelli and purely handmade the same and more perfect than purely handmade, because the machinery and noodles more uniform than artificial, the second and third equipment to produce vermicelli steps with pumping, the advantages of the appearance of a more flat, uniform thickness, but the taste is not good, the third equipment belongs to the production line, the highest output per hour up to 2000KG, this type of equipment is the vermicelli processing industry said that the steam pot. Steam cooker.
Fifth, the finished product and the finished product sales:
We do invest in the construction of this project is to produce finished products to bring benefits, benefits are the key to production and survival, how to control the quality of the finished product and the psychology of consumers is the core of the entire sales. Deep processing of potato starch is not easy to start investing too much, deep processing of agricultural and sideline products each industry development is best to snowball way to slowly grow their own, the reason is that here you need experience, you need technology, but also the need for the support of the old customers, we can only guarantee the sales in order to have a better development.
In the future development of our ideas can not stay in the pure potato vermicelli fan production and sales, in order to ensure that the pure potato vermicelli fan processing on the basis of producers to be creative, dare to boldly try to innovate the extension of the product, for example: the production of a variety of vegetables crushed slurry mixed with potato starch for production. Like celery juice vermicelli, pumpkin juice vermicelli, carrot juice vermicelli, spinach juice vermicelli, seaweed vermicelli, seaweed vermicelli and other vegetable health care vermicelli products, higher-end can be produced instead of water and starch mixing and stirring to produce big bone soup, beef bone soup, sheep bone soup and other vermicelli products. Nowadays there are such manufacturers in the domestic production, and market sales are very good, this mixed production is also our factory old technician Sun Zhenggun master proposed, such a way of production so that consumers are more intuitively associated with the quality of vermicelli in the guarantee at the same time more fresh creativity and very nutritious collocation, the future of this project is worth the expansion of the market.
Sales at present, we want to alum-free without any additives, pure green health food as the basis for the current market positioning of the product, first of all, we utilize the "all-natural and pollution-free" powder as the main appeal to meet the needs of different consumers, which is the main positioning of our products, in the old customer base, we continue to "no additives", "no additives", "no additives", "no additives", "no additives", "no additives", "no additives". We continue to "no additives, hygiene, pure sweet potato" as the main appeal, low cost, low price, large sales as an advantage.
Six, summary:
The progress of the human mind seems to have pioneers have imitators, there are fantasists have tried, there is even more space to have fantasy and the reality and the ability to not realize that slowly through attempts to grope, there are successes and failures, but the control of the success or failure is still in the hands of the operators, the idea of the adaptability of the most critical.
When choosing equipment, the first thing to consider is the production of equipment and future product sales problems, and then should consider the use of which equipment, equipment, equipment, how to support a more reasonable, more suitable for their own production, the purchase of equipment must be on-site inspection of the equipment manufacturers, and equipment production and sales of their own local exchange of information and their own initial ideas, combined with the explanation of the sales staff and self-judgment to choose the right equipment for their own. The company's products and services are also available in a wide range of colors and sizes.
Things to be done, each industry is initially by association or blind thought combined with the actual construction, sweet potato deep processing project is a small investment, large profits is the majority of potato farmers in the area of a good project to get rich.
