Rice processing technology

Abstract

A rice processing technology comprises the following steps that rice is aired under the sun till the water content of the rice is 18-20%; the temperature in a container is adjusted to be 28-30 DEG C,the pressure of the container is adjusted to be 120-125 kpa, the humidity of the container is adjusted to be 60-65%, the time is 30-35 minutes, then the temperature in the rice hulling container is adjusted to be 24-26 DEG C, the pressure is adjusted to be 90-105 kpa, the humidity is adjusted to be 65-70%, and the time is 25-30 minutes, so that the water content of the rice is 13-15%; the rice isput into a rice milling machine for rice milling; the rice obtained after the rice milling process is graded and sorted, and broken rice which exceeds the requirement is extracted; special-color particles is removed by a color sorter; the rice is polished through a polishing machine. The rice processing technology well starts from characteristics of the rice, and appropriate conditions are provided in the rice processing process so that rice husks can easily fall off, and the broken rice is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a rice processing technology. Background technique [0002] Rice is one of the traditional staple foods in my country, and it is also the main food of the people in southern China. Rice is the basic food for supplementing nutrients. In addition to being rich in carbohydrates, it also contains protein, fat, vitamins and 11 kinds of minerals, which can provide comprehensive nutrition for the human body. Rice contains about 75% carbohydrates, 7% to 8% protein, 1.3% to 1.8% fat, and is rich in B vitamins. The carbohydrates in rice are mainly starch, and the protein contained is mainly rice glutenin, followed by rice gelatin and globulin. High, with a digestibility of 66.8% to 83.1%, it is also the higher one in cereal protein. Therefore, edible rice has higher nutritional value. Rice is sweet in taste and flat in nature. It has the effects of nourishing the middle and nou...

Problems solved by technology

At present, the main problem in rice processing is that due to the stickiness of rice husks, the rice milling process results in a lot of broken rice, resulting in the loss of rice, which also increases the workload of the subsequent broken rice screening process and increases the cost of rice processing. At the same time, the processed grains are different and the taste is not good, which affects the processing quality of rice
