Problems solved by technology

The cooking process can make miscellaneous grains mature more fully, which is a better method for processing refractory grains and miscellaneous grains, but the cooking time is relatively long (generally 30~50min), the efficiency is low, and the process procedures are many, which reduces the overall economic benefits.
[0007] Therefore, the above commonly used techniques have restricted the development of the miscellaneous grains ripening and processing industry to varying degrees.

Embodiment 1

[0031] In this embodiment, red beans are taken as an example to carry out microwave rapid drying and ripening treatment of miscellaneous grains.

[0032] A microwave rapid drying and ripening method for red beans, comprising the following steps:

[0033] (1) Pick red beans with a moisture content of 27-32% and put them in a washing machine for cleaning. The washing machine is a continuous conveyor belt with a bandwidth of 1m. There is a spray device above the conveyor belt, and the red beans are washed repeatedly until there is no obvious in the water after washing. dust and impurities; then put the cleaned red beans on the strainer and drain the surface moisture;

[0034] (2) Lay the red bean mechanical cloth after cleaning and draining in step (1) on the conveyor belt, transport it to the microwave cavity for drying treatment, and use a centrifugal fan to dehumidify at the same time. The power of the microwave is 3~4kw, the temperature The temperature is 75°C, the drying ti...

[0038] In this embodiment, mung beans are taken as an example to carry out microwave rapid drying and ripening treatment of miscellaneous grains.

[0039] A microwave rapid drying and curing method for mung beans, comprising the following steps:

[0040] (1) Pick mung beans with a moisture content of 30-35% and wash them in a washing machine. The washing machine is a continuous conveyor belt with a bandwidth of 1m. There is a spray device on the top, and it is washed repeatedly until there is no obvious dust and impurities in the washed water. , then put the cleaned mung beans on the strainer and drain;

[0041] (2) Lay the mung bean mechanical cloth after cleaning and draining in step (1) on the conveyor belt, transport it to the microwave cavity for drying treatment, and use a centrifugal fan to dehumidify at the same time, where the power of the microwave is 3~4kw, The temperature is 75°C, the drying time is 5 minutes, and the air volume of the centrifugal fan is 3000~3500...

Embodiment 3

[0045] In this embodiment, soybeans are taken as an example to carry out microwave rapid drying and aging treatment of miscellaneous grains.

[0046] A microwave rapid drying and ripening method for soybeans, comprising the following steps:

[0047] (1) Pick soybeans with an initial moisture content of 40-42% and put them in a washing machine for washing. The washing machine is a continuous conveyor belt with a bandwidth of 1m. There is a spray device on the top, and it is washed repeatedly until there is no obvious in the water after washing. dust and impurities; then put the cleaned soybeans on the filter screen and drain the surface moisture;

[0048] (2) Lay the soybean mechanical fabric washed and drained in step (1) on the conveyor belt, and transport it to the microwave cavity for microwave drying treatment. At the same time, use a centrifugal fan to dehumidify. The power of the microwave is 3~4kw, The temperature is 70°C, the drying time is 7 minutes, and the air volu...

Abstract

The present invention provides a coarse cereal microwave rapid drying and curing method. Firstly, the selected coarse cereals are washed and the washed coarse cereals are drained, then the drained coarse cereals are transferred into a microwave cavity to conduct microwave drying at a temperature of 70-80 DEG C for 5-10 min to obtain coarse cereal raw materials with a water content of 5-20%, the dried coarse cereals are directly subjected to microwave curing at 110-125 DEG C for 2-6 min, the cured coarse cereals are cooled naturally, and the cooled coarse cereals are subjected to sealed package to obtain cured coarse cereals. The used microwave drying and curing by the method is high in efficiency, short in time, and simple in operation, and the method provided by the invention can be subjected to continuous production, is obvious in energy-saving effects, and greatly improves the work efficiency. The drying and curing processes are hygienic and clean, and good in bactericidal effects, and can keep the color and luster of the cereals not changed.

Description

technical field [0001] The invention belongs to the technical field of rapid food processing, and in particular relates to a microwave rapid drying and curing method for miscellaneous grains with high efficiency and energy saving, which is beneficial to improving the curing quality of products and is easy to control. Background technique [0002] Miscellaneous grains usually refer to food crops other than the five major crops of rice, wheat, corn, soybeans and potatoes, mainly sorghum, millet, buckwheat, oats, barley, mung beans, red beans, small beans, etc. These miscellaneous grains are rich in nutrients and often Eating can play a health care effect on the five internal organs. Studies have found that oatmeal contains linoleic acid, which can inhibit the rise of cholesterol; buckwheat contains rutin, which can reduce the permeability and fragility of capillaries and restore the normal elasticity of capillaries; It has a special effect. Regular consumption of soybean prod...
