Description

The pulverizing drying system of viscosity fermented feed

Technical field

The present invention relates to a kind of drying system of feedstuff, particularly to a kind of pulverizing drying system of viscosity fermented feed.

Background technology

In prior art, the drying of fermented feed generally adopt fluid bed dryer, state drying tower of living, pipe drier, Combination type drying machines etc..Wherein fluid bed dryer is dried through material using hot blast, and drying temperature is 80 DEG C about；Pipe Formula drying machine adopts logical high-temperature steam in heat exchanger tube as thermal source, to manage outer material and tube wall transmission of heat by contact, and drying temperature is 80 DEG C Left and right；State drying tower of living adopts hot blast as thermal source, and hot blast and material directly contact carry out counter-current drying, and drying temperature is 60 DEG C Left and right.Combination drying adopts two kinds of drying mode combined dryings, and drying temperature is 60 DEG C about.For improve production efficiency, ferment Feedstuff is dried field and adopts pipe drier very universal.

Due to a large amount of enzyme isoreactivity materials can be produced after feed fermentation, if temperature of charge is higher than 50 in dry run ～70 DEG C (different product material heatproof is different), fermented feed easily loses activity, and therefore, fermented feed belongs to thermal sensitivity thing Material.

Because the fresh moister viscosity of fermented feed is big, when being dried using pipe drier, thing easily occurs Material is bonded in and causes hot-spot on tube wall, inequality of being heated, overall poor thermal efficiency；And the heat source medium due to pipe drier The temperature of steam is higher, and after fermented feed product drying, generally existing activity is little, the problem of product degeneration, is such as steamed using low temperature Vapour has that production efficiency is low again.

During using fluid bed drying, material easily bonds agitator, orifice plate and feeder in hothouse content, is not suitable with viscosity Big material.

State drying tower of living is dried using relatively mild hot blast although fermented feed degeneration can be avoided, but dries Overlong time, production efficiency is low, and energy consumption is too high, and material easily bonds agitator and feeder in hothouse content, is not suitable with viscous The big material of property.

Content of the invention

It is an object of the invention to, overcome problems of the prior art, a kind of pulverizing of viscosity fermented feed is provided Drying system, it is possible to achieve online pulverize, separate and drying, production efficiency is high and activity that can keep fermented feed.
