Mechanized processing method: Leaky scoop type process: starch raw materials → making gravy paste → combining powder speculation and kneading → pumping air bubbles → leakage of silk molding → boiling powder paste → cooling powder → cutting off the hanging → condensation → freezing → thawing and drying → (briquette) packaging → finished vermicelli.
Extruding Process: Ingredients and thickening - pulping - discharging - heating and ripening and extruding - cooling - drying - cutting at length - packaging.
The processing of vermicelli is handmade, semi-mechanized, fully mechanized,
Handmade Processing: 1. Battering: Take the moisture content of about 45-50% of the tide of starch, about 2.5 times the amount of powder with the addition of cold water Xu Xu, and with a wooden stick constantly stirring, while adding three thousandths of alum in the tide of starch. Alum can increase the toughness and elasticity of the skin, and there are anticorrosive and hydrophobic effect, so that the product is not easy to absorb moisture and moisture.
2. Molding. Powder spoon to take a little powder paste, into the spinning disk, spinning disk made of copper or white iron, about 20 centimeters in diameter, the bottom of a slightly convex shallow disk. Powder paste to join, that is, the plate floating into the pot of boiling water above, and with the hand toggle rotation, so that the powder paste by the role of centrifugal force followed by the center of the bottom of the plate to the surroundings evenly spread out, while being heated by the bottom of the plate according to the shape and size of the paste of the bottom of the plate molding. To be the center of no white spots, that is, the side of the plate that is out, placed in the water, cooling for a few moments and then take off the molding of the powdered skin in the water to cool. In the molding operation, the powder paste in the powder cylinder needs to be stirred from time to time, so that the thinning is uniform.
3. Drying. Water vermicelli skin with the production of starch when the acid slurry soaked 3 to 5 minutes, you can take off part of the pigment and the surface of the sticky, and can increase the luster. If conditions can also be smoked with sulfur, so that the effect of mildew, bleaching and moth-proof will be better. After dipping or smoked sulfur water vermicelli skin, spread on the bamboo curtain with clean straw to dry, and turned once, so that both sides dry evenly. To be dried to the moisture content of 16 ~ 17%, you can collect or packaged for sale.
Mechanized Processing:
Required Equipment: Vermicelli Machine (with pulping machine, main machine, cutting machine)
Process: Raw Material Selection - Pulping - Feeding - Steaming - Steaming - Cooling - Vermicelli Disengagement - Vermicelli Disengagement - Vermicelli Disengagement - Vermicelli Disengagement - Vermicelli Disengagement Cooling - detachment of vermicelli - vermicelli cutting - vermicelli molding - packaging.
Production method:
1, selection of raw materials: the production of vermicelli can choose high-quality potato starch, sweet potato starch and other starches.
2, and slurry: the selected high-quality starch weighing, proportional mixing of water, and slurry and slurry machine stirred into slurry. Processing with dry starch should pay attention to the starch fully moisturized, and slurry speed should not be too high. Generally controlled at × × rpm, when the best results.
3, feeding: open and slurry machine pulp chamber valve, so that the slurry slowly flow into the powder machine hopper, the flow of slurry in the hopper without interruption is appropriate.
4, rapid steaming, slow steaming, slurry under the operation of the conveyor belt into the steamer in the high-temperature rapid steaming section, quickly set into the slow steaming section after molding.
5, low-temperature cooling, high-temperature ripening of vermicelli, very soft, viscous, not easy to get out of the package, the need for low-temperature cooling, so that the toughness is enhanced.
6, detachment, after cooling by low-temperature powder skin with transportation belt to the cutting machine, automatically cut into segments, conveyed to the next process.
7. Drying. It can be dried naturally or with drying, the taste of drying is generally not as good as natural sun-dried, but the degree of hygiene is a little higher.
