Vibration fluidization drying system

Abstract

The invention relates to a vibrating-fluidized drying system, aiming at carrying out fluidized drying to wet alcohol raw materials. The vibrating-fluidized drying system comprises a vibrating-fluidized bed, a vibrating screen, a monolith crusher, a first gas-solid separator and a first gas valve; the vibrating screen connected with a discharge opening of the vibrating-fluidized bed comprises: a big grain-diameter outlet and a small grain-diameter outlet; the big grain-diameter outlet is connected with an intake opening of the first gas-solid separator by the monolith crusher, and a discharge opening of the first gas-solid separator is connected with an intake opening of the vibrating-fluidized bed. A big grain-diameter material dried and output by the vibrating-fluidized bed is effectively screened and crushed by the vibrating screen and the monolith crusher in sequence, then the big grain-diameter material is crushed to be small grain-diameter and delivered by the first gas-solid separator and the first gas valve to the vibrating-fluidized bed for being continuously dried and finally output from the small grain-diameter outlet of the vibrating screen, thereby realizing the purpose of carrying out vibrating-fluidized drying to the wet alcohol raw materials liable to form bigger blocks.

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
