Description
Technical field
Invention is related to stoving process technical field, specially a kind of stoving process of fresh grain stillage feed.
Background technique
It is well known that distillers ' grains are a kind of traditional auxiliary fodders, still, with the increase of vinasse yield and industrial right
The raising that feeding quality requires, the way that fresh grain stillage is directly used in feed is unrealistic, the quality and storage of Yao Tigao lees feeds
Deposit the time, it is necessary to be processed.From the perspective of vinasse processing, vinasse drying is more thorough method, in west prosperity
There has been mature semisolid vinasse dry treatment process in country, and this vinasse are different from the distinctive spirit stillage in China.And
And the stoving process of current fresh grain stillage feed, problem of environmental pollution can not thoroughly be solved by still remaining, and product yield is low, be raised
It is poor and the problem of a large amount of energy can be wasted with being worth.
Summary of the invention
The stoving process for being designed to provide a kind of fresh grain stillage feed of invention, to solve to propose in above-mentioned background technique
The problem of.
To achieve the above object, invention provides the following technical solutions: a kind of stoving process of fresh grain stillage feed, specific to wrap
Include following steps:
Step 1: 65% moisture fresh grain stillage first carries out level-one drying process, dehydration to 35% moisture by stirring pneumatic drier
Fresh grain stillage；
Step 2: and then de- rice husk processing, the rice husk of acquisition are carried out by mechanical sifter to 35% moisture fresh grain stillage of acquisition
The straight burning hot air of stirring pneumatic drier work is supplied to for chaff-fired boiler burning；
Step 3: Vapojet dryer finally is led to 35% moisture fresh grain stillage of de- rice husk and carries out secondary drying processing, dehydration is extremely
12% moisture fresh grain stillage, the hot steam that the rice husk of acquisition is supplied to hot steam drying machine to work for chaff-fired boiler burning.
Preferably, it is provided between the chaff-fired boiler and the stirring pneumatic drier for being carried out to straight burning hot air
The dust removal filter of dust separation.
Preferably, the hot steam drying machine includes incubator, drying box, conveying device, feed hopper, discharge bucket, heat steaming
Vapor inlet and condensation-water drain, the interior setting drying box of the incubator, the interior setting conveying device of the drying box, institute
The top for stating drying box one end connects the feed hopper, and the lower part of the drying box other end connects the discharge bucket, the guarantor
One end upper surface of incubator connects the hot steam import, and one end lower surface of the incubator connects the condensation-water drain.
Preferably, the upper end of the feed hopper extends to outside the upper surface of the incubator, and the lower end of the discharge bucket is prolonged
Outside the lower surface for reaching the incubator, the surrounding edge and the incubator of the incubator and the feed hopper and discharging
The surrounding edge sealing welding of bucket.
Preferably, the lower end consistency from top to bottom of one end of the conveying device and the feed hopper is arranged, the conveying device

Preferably, the hot steam import is connect by pipeline with the steam (vapor) outlet of the chaff-fired boiler, the condensed water
Outlet is connect by water-delivery pump with pipeline with the water inlet of the chaff-fired boiler.
Compared with prior art, advantageous effect of the invention is: the stoving process of the fresh grain stillage feed is segmented using second level
Dry process combination, the dry fresh grain stillage moisture of level-one are down to 35% or so from 65%；Secondary drying drops fresh grain stillage moisture from 35%
To 12%, safe storage is realized；In level-one drying process, fresh grain stillage moisture content is high, belongs to constant-rate drying period, this section
Drying purpose improves dried medium temperature using rapid, high volume dehydration as very wise move, increases heat transfer and mass transfer force, the drying of this section
Medium uses the straight burning hot air through dust separation, and for temperature at 500 DEG C or so, the huge temperature difference and moisture pressure difference promote fresh grain stillage
Moisture fast vaporizing, fresh grain stillage temperature rise are not above the adiabatic saturation temperature of humid air under this state.Level-one dries discharge, material temperature
At 50 DEG C or so, as the volatile ingredient that chemically burns contained in hot-air, if pollution can be generated to vinasse, factually test table
Bright, level-one drying time is shorter, and quick heat and mass is carried out around fresh grain stillage particle, is covered with a large amount of humid air, belongs to non-
Equilibrium state, harmful components are also difficult to be adsorbed by fresh grain stillage at this time, and the dry first stage is to be completed, so will not produce to vinasse
Raw pollution；The rice husk prepared in entire technique is supplied to chaff-fired boiler to burn to required for level-one drying and secondary drying offer
Energy, economize on resources.
