Convenient rice is mainly composed of staple rice, accompanied by dishes, seasonings, three parts. There are many types, according to the different processing methods, can be divided into quick-cooking rice (alpha rice), canned rice, soft canned rice (steamed bag of rice), aseptic packaging rice, frozen rice, refrigerated rice and dry rice seven categories.
1, dehydrated dry rice
That is, by dehydration and drying of rice products, this product can be eaten after a few minutes of rehydration in hot water. Dehydration drying rice is divided into instrumented rice, frozen rice, puffed rice and so on.
2, finished rice
that is, non-dehydrated dry rice, this product does not need to be rehydrated before consumption, open the package can be consumed, can also be heated before consumption
3, boiled water brewing type
such as the thousands of cereals, etc., easy to carry, storage, rice grains, glutinous, grains of rice varieties; subdivided into quick-cooking rice and fiber meal.
4, canned
such as Merlin, etc., the advantage is that the can can be eaten, the disadvantage is that it can not be heated and unfavorable to carry
5, frozen
including refrigeration, aseptic packaging, and frozen type. Cooked rice is stored in low temperature, the advantage is good taste, the disadvantage is the high price, inconvenient to carry.
Instant rice processing production process
1, raw material processing
With the standard No. 2 rice as raw materials, remove the bran, weighing, and put into the rice tank soaked in water, the amount of water to cover over the rice 10 centimeters is appropriate. Soak for half an hour, together with the water into the rice tank under the basket, put the side of the stirring, and rinse with water. Washed rice in the basket to stand for 2 to 4 hours (in the winter soak rice time should be short, standing draining time can be extended appropriately), leaching excess water in the rice (so that the moisture content is less than 30%), and then use the milling machine will be crushed into dry milling powder, dry milling powder by the reciprocating vibrating sieve (50 mesh) through the sieve, falling into the powder tank. The dry milling powder stays here for more than half an hour, so that the moisture on the surface of the powder particles penetrates into the interior to achieve an even distribution of moisture inside and outside. At the same time, take samples to determine the moisture content of the dry grinding powder.
2, cooking and molding
Take the sifted dry grinding powder and weigh it. Every 40 kilograms of a batch, poured into the mixing cooking barrel, according to the determination of the water content of dry milling powder for the amount of water that should be added, so that the water content of the powder reaches 38%. Turn on the mixer to make the powder and water mixing, steam cooking for 4~5 minutes, extrusion molding. First coarse pressure, then fine pressure, so that the powder extruded into the diameter of 0.6 millimeters of rice vermicelli. The powder is extruded from the perforated plate of the press to form four rice vermicelli belts, which fall synchronously onto the cooling conveyor belt up to 10 meters long, and sent to the cutting table to be cut into 22-cm long rice vermicelli segments, which are then folded into U-shape blocks, laid flat on the porous aluminum plate, placed in the steaming cabinet, and then steam-cooked for 10-16 minutes, and then transferred to the baking room.
3, drying detection
The rice flour is loaded on the baking car after the second steaming, and then pushed into the baking road in the drying room with the car, and then slowly moved forward against the direction of hot air by the winch traction, so that the baking car is moving forward against the direction of hot air. The humidity of the hot air in the drying room is 40±2℃, and the air volume is 7425m3/hour. Rice flour in the drying room baked 3~5 hours, until the moisture content of 11~13%. The baking car will be launched, the first sense of the rice flour inspection, if any does not meet the requirements, selected to put another, degraded processing, meet the requirements of the plastic bag sealing, or cellophane packaging dense does not meet the requirements of the other, selected to put another, degraded processing, meet the requirements of the plastic bag sealing, or cellophane packaging sealing. Then by the laboratory personnel sampling check the physical and chemical indicators of rice flour, to meet the standards of the batch is a qualified product, acceptance into storage.
Self-heating rice edible guide
1, edible methods
Canned rice: open the can can be used.
Dehydrated rice quick-cooking rice: add boiling water and soak for a few minutes to serve.
Semi-dried rice preserved rice: just microwave it.
Self-heating rice: just place the heating pack in cool water and wait for 8-15 minutes to heat up.
