Problems solved by technology

Poor dry humidity control during processing leads to high broken rice rate in the processed rice
In addition, in the above-mentioned rice processing process, the material must go through several mechanical friction procedures before it can become a finished product. During the friction process, the temperature of the material rises, generally at 25°C to 37°C, and even as high as 40°C in summer. The rice processed by the follow-up procedure has a relatively high ratio of broken rice and broken rice, and the gloss of the rice is not good. The original fragrance will be lost in the high temperature environment. If it is finished in the state of the package, a small amount of water vapor will condense in the packaging bag, the product is easy to deteriorate, and the shelf life is short

Embodiment 1

[0042] Embodiment 1, the present invention is a kind of processing method that reduces the broken rice rate of rice, comprises the following steps:

[0043] 1) Paddy screening: use drum primary cleaning sieve and vibrating sieve to carry out preliminary cleaning of paddy to remove weeds, branches and leaves in paddy;

[0044] 2) Stone removal: Use a stone removal machine to remove soil, sand and gravel mixed in rice;

[0045] 3) Magnetic separation: use a magnetic separator to remove iron-containing impurities mixed in the rice;

[0046] 4) Moisture measurement, drying or atomization: measure the moisture of rice, control the moisture content of rice at 27-30%, if the moisture content is too high, use an automatic constant temperature heating device to heat the rice to remove excess moisture; if the moisture content is too low , use atomization to increase the water content of rice, maintain the water addition rate of 0.8% / hour before the water content reaches 20%, and slowly...

Embodiment 2

[0058] Embodiment 2, the present invention is a kind of processing method that reduces rice broken rice rate, comprises the following steps:

[0059] 1) Paddy screening: use drum primary cleaning sieve and vibrating sieve to carry out preliminary cleaning of paddy to remove weeds, branches and leaves in paddy;

[0060] 2) Stone removal: Use a stone removal machine to remove soil, sand and gravel mixed in rice;

[0061] 3) Magnetic separation: use a magnetic separator to remove iron-containing impurities mixed in the rice;

[0062] 4) Moisture measurement, drying or atomization: measure the moisture of rice, control the moisture content of rice at 28-29%, if the moisture content is too high, use an automatic constant temperature heating device to heat the rice to remove excess moisture; if the moisture content is too low , use atomization to increase the water content of rice, maintain the water addition rate of 0.8% / hour before the water content reaches 20%, and slowly increa...

Abstract

The invention relates to a processing method allowing lower broken rice rate and belongs to the technical field of rice processing. The processing method includes the steps of rice screening, stone removal, magnetic separation, moisture measurement and drying or atomizing, hulling, husked rice separation, thickness classification, moisture measurement and drying or atomizing, rolling, white rice classification, cooling, polishing, color sorting, water content detection, and sterilizing and packaging. The rice processed by the processing method is low in broken rice rate, long in shelf life and good in glossiness, and flavor of the rice is rarely lost.

Description

technical field [0001] The invention relates to a processing method for reducing the rate of broken rice, and belongs to the technical field of rice processing. Background technique [0002] Rice is the largest food variety in China. Chinese people use rice as a staple food. It is accepted by almost 100% of the people because of its delicious taste and long-term appetite. Moreover, rice products have unique aromatic flavors and are easy to digest. Therefore, rice and Its products have the most extensive consumer objects, huge development potential and broad market, and its research and development have great social and economic benefits. Its processing methods have been continuously improved and improved with the advancement of science and technology. The current rice processing method is: raw rice → preliminary cleaning → hulling → paddy separation → thickness separation → rice milling with sand rollers → rice milling with iron rollers → fine milling → white rice grading → ...
