DEVICE FOR PRE-HUMIDICATION AND HEATING OF GRAIN MASS Russian patent published in 2021 - IPC F26B9/06 F26B3/06 F26B3/20 

FIELD: agriculture.

SUBSTANCE: present invention relates to the agriculture industry, namely to the storage of food products under specified temperature and humidity conditions, due to their compliance, the terms of safe storage are increased and the original quality of products aimed at long-term storage is preserved. The walls of the device are made out of heat-insulating material. To heat the grain mass a heating cable is used. The step of laying the heating cable in the grain mass is from 0,04 to 0,1 meters between the layers with the size of the air distribution grid cell from 0,004 to 0,007 meters. When the heating cable is switched on, it is necessary to close the device cover tightly. The process of heating the grain is implemented at the rate from 2,75 to 3,7°С per hour. To moisten the grain mass, a humidifier is installed in front of the air intake, spraying from 400 to 1000 ml of liquid per hour. In order the grain mass to be moistened and not dried, the air filtration rate should be from 0,5 to 6 cm/s, the height of the grain layer – from 0,6 to 1,2 meters.

EFFECT: uniform heating and moistening of the grain mass according to the specified temperature and humidity values, which ensures increased safe storage time.
