Abstract

The invention discloses a drying agent used for storing unhusked rice. The drying agent used for storing unhusked rice is prepared from the following raw materials in parts by weight: 30-40 parts of calcium chloride, 15-20 parts of wheat straw, 5-10 parts of activated carbon, 15-20 parts of modified starch, 10-15 parts of montmorillonite clay, 10-15 parts of glycerine, 3-6 parts of silicon dioxide, 8-15 parts of ethanol, 5-10 parts of nano-scale rubber powder, 2-5 parts of SiO2-alginates, and 2-5 parts of polyvinylpyrrolidone-graphene oxides. The drying agent used for storing unhusked rice prepared according to the invention is prepared by using safe and non-toxic materials, and thus, the prepared drying agent used for storing unhusked rice is pollution-free to the environment and rice; moreover, the drying agent used for storing unhusked rice is capable of reducing production of mildews and insects in rice, and good in dehumidification effects. The drying agent used for storing unhusked rice has especially good quality and long-lasting effects in the summer as a porous drying agent, and is free of influence on rice quality; moreover, the porous drying agent is compact in aperture,so that, better moisture absorption effects can be achieved. The drying agent used for storing unhusked rice is convenient to use, as well as free of pollution to goods and the environment.

Description

Technical field: [0001] The invention relates to the technical field of rice storage, in particular to a desiccant for rice storage. Background technique: [0002] Rice, botanically belongs to the common rice subspecies in the common cultivated rice subgenus of the genus Poaceae. It is one of the most important food crops in my country. At present, the sown area of ​​rice in my country accounts for about 1 / 4 of the total area of ​​food crops, and its output accounts for about 1 / 2 of the country's total grain output, accounting for more than half of the commercial grain. The production areas are all over the country. [0003] Paddy is sensitive to the influence of temperature and humidity, has strong hygroscopicity, and has a large amount of bacteria, which is easy to be directly damaged by pests and molds. Under the condition of high temperature and high humidity, the respiration intensity of rice is extremely high, and it is easy to generate heat. When the moisture conten...
