Gradual cooling type rice drying system

Abstract

The invention discloses a gradual cooling type rice drying system. The system comprises a drying silo and a draught fan, wherein an air suction port of the draught fan communicates with a drying machine, a feeding port in the upper end of the drying silo communicates with a feeding hopper through a feeding pipe, an unloader is installed on the feeding pipe, a belt conveyor is arranged below a discharging port in the lower end of the drying silo, multiple sets of drying devices are sequentially arranged in the drying silo from top to bottom, each drying device comprises two partition plates which are fixedly connected in the drying silo in parallel at an interval, one end of a flashboard penetrates through the outer wall of the drying silo and then is fixedly connected with a connecting plate, two air cylinders push the flashboard to move in two sliding grooves, so that through holes in the flashboard are staggered with a filter pipe, each air inlet pipe in each group of drying devicescommunicates with a fan, and a valve and an electric heater are mounted on each air inlet pipe. According to the system, rice can be dried step by step at different temperatures, and the problems thatrice drying is not thorough, and rice is prone to drying cracking are solved.

Description

technical field [0001] The invention relates to a gradually cooling paddy drying system. Background technique [0002] After the rice is harvested, it contains a lot of water and cannot be put into the warehouse immediately. It needs to be dried or dried, otherwise the rice will become moldy after being put into the warehouse. On the other hand, if the water content of the rice is too high, it will generate heat. Calmly leads to the hatching of insect eggs in the rice, which increases the destructive effect of diseases and insect pests, so the drying and drying of rice before storage is essential. The existing drying method for rice on the market is generally to put the rice into a silo and let it fall naturally, then input countercurrent hot air into the silo, and use the countercurrent hot air to dry the naturally falling rice. For example, the patent number is: "CN201207888Y ", the patent name is "small-scale paddy quality-preserving dryer", which repeatedly returns the ...
