Embodiment 1

[0029] A kind of grain low-temperature drying process for the grain production line of the present embodiment is characterized in that it comprises the following specific steps:

[0030] (1) Wind separation and impurity removal: the grain to be dried is sent into the air separation machine through the feeder for air separation to remove most of the impurities;

[0031] (2) Secondary impurity removal: send the grains that have been air-selected and impurity-removed into the dust removal sieve for secondary impurity removal and dust removal;

[0032] (3) Sampling identification: carry out sampling identification on the grain that has completed the secondary impurity removal, and identify its moisture content;

[0033] (4) Low-temperature drying: use low-temperature drying equipment to dry the sampled grain at low temperature;

[0034] (5) Discharging: After the low-temperature drying is completed, the grains are discharged and stored.

[0035] The above-mentioned low-temperatu...

Abstract

The invention discloses a grain low-temperature drying process for a grain production line. The grain low-temperature drying process for the grain production line is used for drying work before grain storage, and comprises multiple steps of winnowing impurity removal, secondary impurity removal, sampling and identification, low-temperature drying and discharging. The drying parameters are regulated and controlled based on the grain moisture content, and the moisture content in the grain can be effectively adjusted while ensuring the grain quality, so that the grain meets storage standards. The grain low-temperature drying process for the grain production line is reasonable in design, easy to operate, high in grain drying efficiency, high in precision and low in drying cost.

Description

technical field [0001] The invention relates to the technical field of grain storage, in particular to a grain low-temperature drying process used in a grain production line. Background technique [0002] There is an old saying in China that "food is the most important thing for the people", which means that the people depend on food for their lives. With the improvement of people's living standards and the development of cooking techniques, people's per capita consumption of food is also increasing. At the same time, with the level of agricultural technology and the development of new food types, the output of food is also steadily increasing. [0003] In order to ensure people's living needs and national security needs, all localities are equipped with relevant grain storage facilities. In order to ensure storage safety and improve the storage period of grain, the moisture content of grain needs to be strictly controlled in storage, and effective drying is required. opera...
