Vibration fluidization drying system

Abstract

In order to fluidize and dry wet alcohol raw materials, the present invention relates to a vibrating fluidized drying system, which includes: a vibrating fluidized bed, a vibrating screen, a whole material crusher, a first gas-solid separator and a first shut-off fan; The vibrating sieve connected to the discharge port of the vibrating fluidized bed includes: a large particle size outlet and a small particle size outlet; the large particle size outlet is connected to the feed port of the first gas-solid separator through the whole material crusher, and the first gas-solid separator is connected to the first gas-solid separator. The discharge port of the solid separator is connected with the feed port of the vibrating fluidized bed through the first shut-off fan. The raw materials with large particle size output through vibrating fluidized bed drying are effectively sieved and crushed after passing through the vibrating screen and the whole material crusher in turn, so that the raw materials with large particle size become small particle sizes, and then go through the first gas-solid separation process. The device and the first shut-off fan are sent to the vibrating fluidized bed for continuous drying, and finally output from the small particle size outlet of the vibrating screen. Thereby, the purpose of fluidized drying of wet alcohol raw materials that are easy to form larger lumps is realized.

Description

technical field [0001] The invention relates to a vibrating fluidized drying system for fluidized drying granular materials. Background technique [0002] Existing vibrating fluidized bed dryers, such as the vibrating fluidized bed device disclosed in Japanese Patent JP1245847, the vibrating fluidized bed dryer disclosed in Chinese patent document CN2042584U, the disclosed fluidized bed dryer in Chinese patent CN2077531U, China Patent CN2201633Y discloses a vibrating compound fluidized bed dryer. Although they are different in structure, what they have in common is that the vibration excitation force is introduced into the gas fluidized bed, so that the material particles are subjected to the vibration excitation force and become jump fluidized. In this state, all the heat required for drying is provided by the hot air from the outside. [0003] Chinese patent document CN2833468 discloses a kind of return type fluidized bed drying equipment, including feeder, fluidized bed,...

AI Technical Summary

Problems solved by technology

[0005] The weak point of above-mentioned prior art is: can not carry out effective fluidized drying to wet alcohol raw material (comprising: maltitol, xylitol, maltose and xylose etc.)

These wet alcohol raw materials are crystals with good fluidity. There is often surface water on the crystals, and the air at room temperature is prone to moisture, so it is easy to form larger lumps. The existing fluidized bed drying equipment cannot effectively pulverize them. and dry, and unable to control its humidity
