Drying technique of viscous strain material and equipment thereof

Abstract

The invention discloses a drying technique of a viscous strain material and equipment thereof. The equipment is characterized in that a colliding grid (5) and a turbulent flow grid (6) are additionally arranged above the inner wall of a main pipe tower (2) and a crusher (4) so as to lead the dried material to collide with the colliding grid for being fined, simultaneously the dried fine particle material prolongs the exchange time of the wet material and high-temperature hot air by the buffering effect of the turbulent flow grid (6) in the main pipe tower, thus achieving the effect of improving vaporization and dehydration. The technique process is as follows: the obtained viscous strain material by the membrane concentration technique and the hot air are simultaneously delivered into thedried main pipe tower (2) for crushing and drying to form particles; and the particle powder enters a whirlwind material receiving machine (11) by an air-inducing pipe (8) for separation and collection of products. The invention can fast improve the dehydration effect of materials, has good viscous-material drying effect and high drying efficiency, effectively guarantees active components of the strain, and has low energy consumption, large drying strength, noncaking finished products and high yield.

Description

A drying process and equipment for viscous fungus material technical field The invention relates to a process for drying sticky wet materials containing bacteria species and equipment for the process. Background technique Among the currently widely used drying methods for water-containing materials, the drying effect of vacuum drying, freeze drying and hot air circulation oven is not ideal. Not only is the drying uneven, easy to agglomerate, low efficiency and long drying time, but also manual operation is required for feeding and discharging materials. , Susceptible to pollution, harsh operating environment. Freeze-drying and vacuum-drying, which are widely used in the fields of pharmaceuticals and bioengineering, require large-scale equipment, and it is difficult to adopt continuous production steps, making the production method cumbersome and laborious. Spray drying is a relatively advanced drying equipment at present, but the existing technology and equipment have a l...
