Method for improving head rice rate of rice grains

Abstract

The invention discloses a method for improving the head rice rate of rice grains. The method comprises the following steps of A, rice harvesting, B, unhusked rice airing and C, warehousing storage. The step A of rice harvesting further comprises the step that a machine is adopted for harvesting, and a micro grain combine-harvester is utilized for harvesting and threshing of unhusked rice. The stepB of unhusked rice airing further comprises the step of evenly paved on the unhusked rice on a cement ground to be aired by sunlight. The step C of warehousing storage further comprises the step thatthe water content of the harvested unhusked rice of the same batch is detected, and when the water content is lower than 14%, the unhusked rice is put in a refrigeration house to be stored. Accordingto the method, through different storage time limits and storage conditions and the influence of the head rice rate of the unhusked rice, the storage temperature and humidity parameters are determined, a time limit and temperature and humidity combined adjustment scheme for a large quantity of unhusked rice is formed, and the head rice rate of the unhusked rice is improved.

Description

technical field [0001] The invention relates to the field of biotechnology for improving the quality of agricultural products, in particular to a new method for improving the rice polishing rate in the actual cold storage process. Background technique [0002] Rice is one of the most important food crops in the world, and about half of the world's population uses rice as a staple food. my country's annual rice output ranks first in the world. In 2016, the national rice sown area was 30.16 million hectares, and the total rice output was 206.934 million tons. With the improvement of people's living standards, the requirements for rice quality are getting higher and higher. However, there is a general contradiction between "high quality and high yield" between this and the hybrid rice currently promoted in my country. [0003] The overall low quality of hybrid rice is the main reason why my country's rice lacks market competitiveness. The quality of hybrid rice is mainly ma...

Problems solved by technology

There are detailed studies on the effects of the storage time and conditions of a small amount of rice on the rice trimming rate under laboratory conditions, but there is little explanation of the effect of the storage time and conditions of a large amount of rice in the actual cold storage on the rice trimming rate
