Rice insect-proof storage method

Abstract

The invention discloses a rice insect-proof storage method which comprises the following steps: removing impurities and drying, i.e., removing the impurities from harvested unhulled rice sequentiallyby an impurity removing machine, a stone removing machine and a magnetic separator; spreading the unhulled rice subjected to impurity removal to carry out hot air drying treatment, carrying out hot air preheating to the temperature of 40 to 60 DEG C until the water content of the unhulled rice is 10 to 15%, and then carrying out natural cooling to the room temperature; carrying out hulling and fresh preservation, i.e., sequentially processing the unhulled rice by a rice huller, a husked rice separating screen and a rice milling machine to obtain rice, carrying out spraying fresh preservation treatment, and spreading the rice under the natural wind to cool to the temperature of 15 to 25 DEG C; carrying out insect-proof storage, i.e., packaging the cooled rice, placing the packaged rice in awarehouse, spraying insect-proof liquid into the internal environment of the space of the warehouse so as to implement insect-proof treatment, and then sealing the warehouse; and carrying out ventilation treatment, i.e., carrying out fresh air replacement on air in the warehouse at each interval of 2 to 3 days, and spraying the insect-proof liquid again. According to the invention, the preservedrice is difficult to mildew and rot, is difficult to damage by worms, gloss and fragrance can be kept for a longer time, and the rice insect-proof storage method is valuable to popularize.

Description

technical field [0001] The invention relates to the field of grain storage, in particular to an insect-proof storage method for rice. Background technique [0002] my country is a country with a large population and a large agricultural country. Food security is particularly important, especially food preservation. Due to the loss of the shell and peel of rice, the hydrophilic colloid of rice grains rich in nutrients is extremely vulnerable to insects and molds. In addition, rice contains varying degrees of bran layers and rice grains are exposed, directly in contact with the temperature and humidity of the external environment, which is easy to absorb moisture and easily Exploding waist and easy aging, so rice is more difficult to keep fresh than paddy and brown rice. For a long time, due to the backwardness of fresh-keeping technology, the loss of my country's rice in the process of storage, transportation and marketing has reached more than 10%-15%. [0003] In order to...

Problems solved by technology

[0003] In order to solve these problems, some people often spray some chemical pesticides when storing rice, but the residual chemical agents will affect the health if eaten by people or poultry and livestock

In addition, in the process of grain storage, it is easy to mold and deteriorate
