Drying cooler of fluidized bed

Abstract

The invention discloses a drying cooler of a fluidized bed in the field of feed processing devices. The drying cooler comprises a material feeder connected with a feeding hole of a drying bin, wherein the drying bin is internally provided with a conveyer belt which is provided with air holes, a vibrator controlling the vibration of the conveyer belt is arranged below the conveying belt in the drying bin, an air inlet is formed in the lower part of the drying bin, an air outlet is in the upper part of the drying bin, the air outlet is connected with an exhaust fan through a deduster, the air inlet is connected with an outlet of a heat exchanger, an inlet of the heat exchanger is connected with an outlet of an air feeder, and an inlet of the air feeder is connected with an air filter. According to the invention, by means of the working action of vibration and hot air, materials advance in a wavy manner on the conveyer belt, so that the heat transfer effect is good, the drying efficiency is high, the humidity distribution is uniform, and the drying cooler is simple in structure and lower in investment cost and can be applied to drying of granular materials.

Description

technical field [0001] The invention relates to a feed processing device, in particular to a dryer. Background technique [0002] The pellet feed dryer is mainly used for the drying of the aquatic pellet feed post-curing and the drying treatment of the extruded feed. Its main working principle is: on the basis of the ordinary cooler, add a heat exchange device (function) to adjust the humid and hot state of the air medium , to provide dry air medium dry, to achieve the purpose of balanced precipitation. [0003] Variables and factors affecting drying mainly include operating temperature, air humidity, air distribution, drying time, product distribution, product type and quality, air flow and air velocity, etc. Most of the dryers in the prior art are due to their structure The reason is that the heat transfer effect is poor, the humidity distribution is uneven, the operation is complicated, the production cost is high, Contents of the invention [0004] The object of the ...
