Method for producing coarse cereals rice by extruding double screw

Abstract

The invention relates to a method for producing coarse cereals rice by extruding a double screw, wherein, the coarse cereals rice takes five cereals as raw materials. The method comprises the following steps: pretreating the raw materials, stirring the raw materials in a mixing way, extruding and curing the raw materials at one time with a double screw extruder and a double screw extruding technology; graining and shaping the raw materials; drying the raw materials; and cooling the raw materials, etc. The coarse cereals rice absolutely takes five cereals as raw materials without any additives and ancillary materials. The coarse cereals rice has various external shapes according to requirements, has a compact structure without the need for polishing, stable quality, good edible quality, balanced nutrition and strong health function, is free of cleaning and convenient, can be stored for a long time, has good heat stability when being cooked, and can be eaten as staple food as the common rice. The invention has the advantages of high production, continuous production process which is especially suitable for large-scale industrialization production, stable product quality, low cost, small production floor space, etc.

Description

technical field [0001] The patent of the present invention relates to a method for producing miscellaneous grain rice, in particular to a method for producing miscellaneous grain rice by twin-screw extrusion. Background technique [0002] Miscellaneous grains are recognized as pollution-free green food, which contain natural protein fat, carbohydrates, vitamins, minerals and dietary fiber and other nutrients, which meet the reasonable ratio of human intake, and have high utilization value. It contains a variety of unsaturated fatty acids, such as oleic acid, linoleic acid, linolenic acid, phospholipids, oligosaccharides, polysaccharides, and flavonoids, which have the functions of preventing and resisting diseases, enhancing immunity, and delaying aging . Although miscellaneous grains have many advantages in terms of nutrition, due to the different tastes of people in various places, it has caused certain obstacles for people to eat miscellaneous grains for a long time.

Problems solved by technology

At present, there are not many processing methods for miscellaneous grains, and most of them stay in simple processing. The miscellaneous grains are crushed and mixed together to make miscellaneous grain powder, or mixed with various miscellaneous grain powders, and granulated by a general granulator. Although the processing method retains the nutrients of the grains, but because the processing is simple, it does not bring about major changes in the organizational structure of the grains, and does not really improve the taste of the grains and the digestion and absorption of the nutrients. At the same time, the existing Processing method The follow-up process is more complicated. Due to the rough surface of the granules produced by the granulator, polishing treatment is required in the post-processing process. In the process of polishing and granulation, it is also necessary to add bonding materials, such as starch, etc.
