Intelligent normal-pressure far infrared drying method for frozen grains

Abstract

The invention relates to an intelligent normal-pressure far infrared drying method for frozen grains. The intelligent normal-pressure far infrared drying method for the frozen grains comprises steps as follows: real-time monitoring is performed by means of temperature sensors, humidity sensors and weight sensors in a drying machine in a multi-stage far infrared irradiation heating manner, and the radiation power of far infrared heating plates and the speed of material conveying belts are regulated in real time; the dried grains heated through multi-stage far infrared irradiation are cooled and stored in a grain storage chamber; a large amount of vapor generated in the grain drying process forms air flows downwards flowing smoothly under the joint action of an upper hot environment in a drying chamber, a lower precooling environment at condensation air pipes and a cold environment provided by vapor catchers; the drying machine comprises the drying chamber, the humidity sensors, the temperature sensors ad the far infrared irradiation heating plates are arranged in the drying chamber, the condensation air pipes are mounted at the material conveying belt on the fifth layer, and the lower side of the drying chamber is connected with the vapor catchers. With the adoption of the method, grain drying is intelligently and automatically controlled in the whole process, and cold sources are effectively utilized.

Description

1. Technical field: [0001] The invention relates to a method for rapidly drying frozen grains in the northern alpine region in the technical field of grain drying, and specifically relates to an intelligent normal-pressure far-infrared freezing grain drying method. 2. Background technology: [0002] The north of my country is the main producing area of ​​grain. According to statistics, after the grain is harvested, the loss of grain due to mildew and germination due to the cold climate and too little time to dry is as high as 5%. Therefore, the timely drying and storage of grain has become the most important link in the grain industry chain. [0003] At present, in northern my country, grain is dried mainly through natural drying, tower dryers and drum dryers. The natural drying time is long and is greatly affected by the site and the weather; tower dryers and drum dryers generally have problems such as high cost, low thermal efficiency, high energy consumption for drying f...
