Problems solved by technology

[0003] The existing mechanized equipment processes paddy into rice, all of which adopt a one-stop processing method, that is, use a one-stop production line to complete the process from paddy to finished rice in one go. Although this traditional processing technology is more efficient, it is For rice milling, polishing, grading and other processes, mechanized continuous production will greatly increase the cost of rice processing enterprises due to the complicated processing procedures, and at the same time lead to low rice yield and poor finish. The broken rice rate of the processed rice will be high due to the poor control of the dry humidity of the equipment

Embodiment 1

[0016] Collect the early rice, put the rice into the drum primary cleaning sieve to remove the large impurities in the rice, and then remove the medium and small impurities in the rice through the three-stage vibrating sieve, and then send the removed rice into the hopper of the de-stoner machine. The stone machine removes side-by-side stones, and then the stone-removed rice is magnetically separated by a magnetic separator to remove metal substances present in the rice.

[0017] Add 5 parts by mass of edible alkali to 1000 parts by mass of water, mix evenly and heat to 50°C, then add the magnetically separated rice into water and soak for half an hour, rinse with 50°C running warm water for 10 minutes after soaking, rinse After completion, the rice is spread out in a 100-page natural ventilation store and air-dried by cold air to a water content of 30%, and then put into a huller for hulling treatment, and the brown rice and rice husk are roughly separated under the suction of...

Embodiment 2

[0021] Collect the late rice, put the rice into the drum primary cleaning sieve to remove the large impurities in the rice, and then remove the medium and small impurities in the rice through the two-stage vibrating screen, and then send the removed rice into the hopper of the de-stoner machine. The stone machine removes side-by-side stones, and then the rice after stone removal is magnetically separated by a magnetic separator to remove metal substances in the rice.

[0022] Add 5 parts by mass of edible alkali to 1000 parts by mass of water, mix evenly and heat to 60°C, then add the magnetically separated rice into water and soak for half an hour. After soaking, rinse with flowing warm water at 40°C for 10 minutes, rinse After completion, the rice is spread out in a 100-page natural ventilation store and air-dried by cold air to a water content of 28%, and then put into a huller for hulling treatment, and the brown rice and rice husk are roughly separated under the action of ...

Abstract

The invention discloses a rice fine processing technology which comprises the following steps of unhusked rice screening, stone removal, magnetic separation, soaking in a dietary alkali solution, washing, drying and moisture removal, rice husking, husked rice separation, thickness classification, rice milling, soaking in a soaking solution, drying and moisture removal, white rice classification, rice cooling, polishing, color sorting, secondary white rice classification, sterilization and packaging. According to the method, processing technological procedures are simple, the milled rice rate is high, the production cost of rice processing enterprises can be reduced, and the rice produced through the method is clean, good in degree of finish and low in broken rice rate.

Description

technical field [0001] The invention relates to the technical field of agricultural product processing, in particular to a rice finishing process. Background technique [0002] As the largest grain variety in my country, rice has the most extensive consumption objects, huge development potential and broad market, and its research and development has high social and economic value. Generally speaking, the traditional rice processing process basically includes cleaning, husking, separation of rice and husk, rice milling, and rice polishing. The processing methods continue to develop with the improvement of people's living standards and show a trend of mechanization. [0003] The existing mechanized equipment processes paddy into rice, all of which adopt a one-stop processing method, that is, use a one-stop production line to complete the process from paddy to finished rice in one go. Although this traditional processing technology is more efficient, it is For rice milling, po...
