Novel selenium rich rice processing process

A new process, the technology of selenium-enriched rice, applied in the direction of grain degermination, grain processing, grain milling, etc., can solve the problem that the shelf life of the finished selenium-enriched rice is not long enough, the hulling rate of the rice is affected, and the rice is susceptible to bacterial infection and deterioration. and other problems, to avoid overheating of rice, facilitate long-term storage, and facilitate shelling processing.

Problems solved by technology

[0004] On the one hand, due to the unreasonable pre-treatment process, during the processing of rice, the strength of rice particles is not enough, and at the same time, it is difficult to hustle the rice, which affects the husking rate and the integrity of the rice in the rice processing process, thereby reducing the quality of rice processing and making The proportion of broken rice increases; on the other hand, due to the unclean removal of gravel and sundries during the processing process, there are sundries after rice processing, which reduces the purity of rice; on the other hand, due to the post-processing of finished products and packaging Inappropriate, resulting in the shelf life of finished selenium-enriched rice is not long enough, rice is susceptible to bacterial infection and deterioration, which affects the safety and quality of rice

Embodiment 1

[0031] A new process for processing selenium-enriched rice, comprising the steps of:

[0032] (1) Dehumidification: Spread a layer of nylon mat on the indoor floor, place selenium-enriched rice on the surface of the indoor nylon mat, use wooden boards to flatten the selenium-enriched rice to form a rice accumulation layer with a thickness of 2cm-3cm, and then use air conditioning or Dry and dehydrate the selenium-enriched rice with a hot air blower at 28°C-32°C, and dehydrate the water content of the rice to 13%-14%; Turn over and dry, so that the dehydration efficiency is higher and the drying speed is faster;

[0033](2) Impurity removal: place the rice filter sieve at a height of 1.5m-2m from the ground, place a container or lay a layer of mat directly under the filter sieve, and pass the selenium-enriched rice through the filter sieve to remove relatively large impurities. During the process of the selenium-enriched rice falling to the ground through the filter sieve, a f...

Embodiment 2

[0046] As a preferred version of the present invention, in the dehumidification step, the number of times of turning and drying the selenium-enriched rice is 5-6 times, so as to improve the drying quality of the selenium-enriched rice and make the drying more uniform; at the same time, the sterilizing The sterilizing treatment time in the steps is 10min-20min, and the sterilizing space is in a vacuumed and sealed state, which is beneficial to sterilizing the infectious bacteria existing on the surface of the rice, improving the safety of the rice, and facilitating long-term storage of the rice.

[0047] Through the further optimization of the above scheme, the quality of selenium-enriched rice has played a good role. After comparison, the selenium-enriched rice of the present application has made great progress in terms of quality preservation compared with the traditional method, and achieved better results. According to the technical solution of the present invention, after ...

Abstract

The invention relates to the technical field of rice processing, in particular to a new process for processing selenium-enriched rice, comprising: (1) dehumidification; (2) impurity removal; (3) primary rice milling; (4) drying; (5) secondary Rice milling; (6) Polishing; (7) Color sorting and grading; (8) Sterilization; (9) Measuring, packaging and other processes have effectively improved the overall quality and safe storage quality of selenium-enriched rice, making the proportion of broken rice relatively high. Reduce to a great extent, because the sale price of complete rice grains is far less than that of complete and plump rice grains, the proportion of broken rice can be effectively reduced by the process scheme of the application, thereby increasing The economic value of the selenium-enriched rice finished product processed by the process can bring better improvement to the economic benefit of the selenium-enriched rice.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a new process for processing selenium-enriched rice. Background technique [0002] Rice is one of the most commonly eaten staple foods. Rice processing in a broad sense refers to the comprehensive processing process from rice husking to polished rice products. The rice processing process basically includes impurity removal, rice milling, polishing, color sorting, grading and packaging. Selenium is an indispensable trace element to maintain the normal functions of the human body. Selenium deficiency in the human body can lead to various diseases. Modern scientific research has proved that selenium has the functions of anti-oxidation, enhancing human immunity, effectively removing harmful waste from the human body, promoting human health, and delaying aging. As a type of rice rich in selenium, selenium-enriched rice has been strongly advocated by countries all over the w...
