Rice drying and turning process for improving whole rice rate and production equipment thereof

Abstract

The invention provides a rice drying and turning process for improving the whole rice rate and the production equipment thereof. The equipment discloses a drying and turning process, and is characterized by specifically comprising the following steps of 1, drying, wherein the rice is dried in hot air, wherein the temperature of the rice is kept at 31 DEG c to 35 DEG c, and the moisture content ofthe dried rice is reduced to 13.5 to 16.5wt%; 2, carrying out a grain covering procedure, conveying the dried rice into a granary for sealing and storing for 48 hours; and 3, turning the warehouse, the rice in the granary is discharged and then is conveyed to the granary again. The equipment comprises a drying bin and a granary. According to the process and the equipment, the whole rice yield canbe effectively improved.

Description

technical field [0001] The invention relates to a process for drying rice and turning bins after drying, and applicable equipment. Background technique [0002] A very critical production parameter of rice is the polished rice rate. Polished rice refers to rice that has been husked into brown rice by an experimental huller, and the brown rice has been milled by an experimental rice mill into a rice with a processing accuracy of the national standard level 3 (GB1354). When the length reaches three-quarters or more of the average length of a complete rice grain. [0003] On the one hand, this parameter is directly related to the yield, that is, the ratio of the rice to the final product on the market, and on the other hand, it is directly related to the quality of the rice, and further to the taste. The low rate of polished rice indicates that the texture of the rice is rough and easily broken, and the taste is not good. The high rate of polished rice can indicate that the t...

AI Technical Summary

Problems solved by technology

[0004] The existing rice basically needs to be turned over during storage after drying, but there are big problems in the control of drying and turning over during production. First, the core temperature in the rice is not controlled, only the air intake is controlled. Temperature, 2. Turning over is too early. The existing turning process is generally carried out within 24 hours after storage, or earlier

These two operations lead to low polished rice rate of existing rice, many broken rice, and poor taste
