Rice making process and device

Abstract

The invention relates to rice making process, which comprises a coarse rice peeling procedure. The coarse rice peeling procedure consists of a wetting procedure and a stirring peeling procedure. The wetting procedure includes steps that water with the weight of 0.5%-2.5% of that of coarse rice is added in the coarse rice by a wetting machine, the temperature of the water ranges from 10 DEG C to 60 DEG C, after being wetted, the coarse rice is conveyed to the stirring peeling procedure to be processed within 10 minutes, the height of the coarse rice is controlled within 0.3m to 2m in the stirring peeling procedure, a stirring machine is used during stirring, and the linear speed of a stirring bar of the stirring machine is controlled within 1-6m / S. The rice making process is used for peeling the coarse rice by a stirring peeling method, action force to the coarse rice is low, soft and balanced, removal rate of a coarse rice skin layer is high, yield of broken rice is low, and economical benefit is remarkable.

Description

technical field [0001] The invention belongs to a paddy processing technology, in particular to a paddy rice production process and a device, which uses a stirring and dehulling process to replace the existing rice milling process, and is especially suitable for a production line for paddy dehulling and dehulling to produce rice. Background technique [0002] Rice grains are composed of two parts: glume (commonly known as rice husk) and caryopsis (also known as brown rice after processing and removing the rice husk). Caryopsis consists of three parts: cortex, endosperm and embryo. The so-called rice processing refers to the process of removing the husk and cortex from rice and turning it into pure endosperm-based rice. The existing rice processing process generally consists of cleaning, hulling (i.e. husking) and separation of hulled matter (including separation of rice and rice husks and separation of rice and brown rice) and rice milling (in the prior art, rice mills are ...

AI Technical Summary

Problems solved by technology

Because of the thin cortex of brown rice and low strength, the strength of brown rice grains is low, and the phenomenon of waist bursting often occurs, most of the cortex of brown rice can be peeled off in one rice milling process, but the rate of broken rice is often too high, so most of the existing technologies use 2 to 3 rice milling process

[0004]The existing paddy milling technology using rice milling has the following deficiencies: (1) Due to the lack of structure and performance of the rice milling machine and the low strength of brown rice and often bursting the waist, resulting in During the rice milling process, the broken rice rate is as high as 25% to 40%.

The high rate of broken rice is the biggest shortcoming of the existing technology

⑵ The brown rice grains entering the whitening area of ​​the rice mill can only be peeled off after repeated high-intensity friction or grinding by the rollers during the traveling process of about 0.4m. Therefore, the energy consumption of the rice milling section is high, and the temperature of the output As the rice grows larger, the edible quality of the finished rice declines

(3) The structure and performance of the rice mill determine that if you want to produce high-precision rice with the conventional production process, you must almost remove the nutrient-rich aleurone layer, sub-aleurone layer and germ, which will lead to excessive nutritional loss of the finished rice.

⑷ A small amount of powdery or fine granular endosperm produced by repeated high-intensity milling and milling is mixed into rice bran, which not only reduces the yield of finished products, but also seriously affects the extraction rate of rice bran oil and the value of deep processing of rice
