Finished grain rice low-temperature storage method

Abstract

The invention relates to a finished grain rice low-temperature storage method. By adopting the finished grain rice low-temperature storage method, the purposes of storing rice at a low temperature, ensuring the quality of the rice and meeting requirements of people for healthy edible rice can be effectively achieved. Unhusked rice is processed into finished rice according to a conventional method,then, the finished rice is warehoused to be subjected to low-temperature storage, a grain cooling machine is adopted to cool a grain warehouse containing the finished rice, the grain cooling machineis controlled by a PLC to decrease the storage temperature of the finished rice to 15 DEG C at a temperature decreasing speed of 0.5-2 DEG C / d, and a humidity adjusting device is used for adjusting the humidity inside the grain warehouse to 55-75%RH; and when a fatty acid value is 5-30 mg / 100 g, a safe storage period is 180 days, when needing to be delivered from the grain warehouse within the safe storage period, the finished rice is stored in a temporary storage bin first, and when a natural environment temperature is 35 DEG C or below, the finished rice can be stored for 20 days to be reprocessed or to be packaged and delivered from the warehouse. The finished grain rice low-temperature storage method is simple, easy to operate, low in cost and good in effect, the quality and edible value of the rice can be effectively ensured, the shelf life of the finished rice is long, the rice is convenient to reprocess, package and sell, therefore, innovation of finished rice low-temperature storage is achieved, and the finished grain rice low-temperature storage method has good economic and social benefits.

Description

technical field [0001] The invention relates to grain storage, in particular to a low-temperature storage method for finished grain and rice. Background technique [0002] Rice is the staple food for more than 60% of the world's population, especially in Asia. my country's rice production ranks first in the world. In 2013, my country's rice production has reached 200 million tons. In addition to being used for people's consumption and processed into other foods, a large amount of rice needs to be stored every year. However, rice storage needs to occupy a large amount of storage space, and has the disadvantages of being unable to respond to emergencies. When regional or natural large-scale disasters occur, finished grains can be quickly mobilized for emergency response to ensure people's food security, and the storage capacity of finished grains storage Compared with rice storage, finished grain rice storage can save about 40% storage area, save valuable land resources, save...
