Abstract
The invention discloses a high-efficiency separation method for distilled grains of Maotai-flavour liquor. The separation method comprises the following steps: controlling the moisture content of fed distilled grains at 40-55% and the moisture content of the dried distilled grains at 10-18%; performing roll compacting with coupled rollers on the dried distilled grains; performing vibration sieving on the distilled grains subjected to the roll compacting by the coupled rollers, wherein the size of each sieve mesh is 6-20 meshes, the vibration frequency is 20-30 times per minute; and separating, thereby obtaining the distilled grains. By virtue of the separation method disclosed by the invention, the chaff in the distilled grains can be separated efficiently, the content of crude fibers of the distilled grains can be reduced and the contents of crude proteins and crude fats can be increased.
Description
Technical field
The invention belongs to brewing technical field, be specifically related to a kind of separation method of Maotai-flavor liquor vinasse.
Background technology
Traditional production technology that the production of Maotai-flavor liquor is being inherited always, the raw material of its production is mainly Chinese sorghum and wheat, production technology adopt solid-state open type fermented, after a production cycle by remaining a large amount of solid by-product-vinasse.In white wine production sweat, main consumption is the starch in Chinese sorghum wheat, crude protein and crude fat content in remaining vinasse are higher, if directly vinasse are abandoned, this is contaminated environment not only, and be a kind of waste of resource, therefore fully utilize vinasse become realize make rational use of resources, the inexorable trend of energy-conserving and environment-protective.But, due in Maotai-flavor liquor production process, before each round pit entry fermentation, all can add a large amount of husks as filler, when getting after drinking through seven rounds, in vinasse, accumulated a large amount of husks, husk content is up to 30% left and right, makes crude fiber content in vinasse up to 18%.If directly as forage feed livestock, the non-constant of the palatability of vinasse, and because crude fiber content is higher, make livestock in digestion process, consume a large amount of energy, thus do not reach the intrinsic feed efficiency of vinasse.Therefore the husk in vinasse is separated, thus the crude fiber content of reduction vinasse, and this is one vinasse is converted into the technical barrier that high feed efficiency feed must be captured.And current various vinasse isolation technics means all can not realize efficient separation vinasse and large-scale production requirement.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming and provide a kind ofly can efficiently separate the husk in vinasse, reduce the crude fiber content of vinasse, increase the separation method of the Maotai-flavor liquor vinasse of crude protein and crude fat content.
The separation method of a kind of aromatic white spirit vinasse of the present invention, comprises the following steps:
(1) dry: by charging vinasse moisture control, at 40-55%, dry rear vinasse moisture content is 10-18%;
(2) roll compacting: dried vinasse are carried out to pair roller roll compacting;
(3) screening: vinasse after pair roller roll compacting are adopted to vibrosieve, and slot size is 6-20 order, and vibration frequency is 20-30 time/min, after separation and get final product.
The efficient separation method of above-mentioned a kind of Maotai-flavor liquor vinasse, wherein: the pair roller roll compacting technology of employing is that the pair roller spacing of pair roller roll compacting equipment is controlled between 1-6mm.
The efficient separation method of above-mentioned a kind of Maotai-flavor liquor vinasse, wherein: rotating cylinder rotating speed is turn/min of 15-30.
The efficient separation method of above-mentioned a kind of Maotai-flavor liquor vinasse, wherein: dry is that employing first order roller drying, dry rear vinasse moisture content are 25-35%, second, third grade of cyclone drying, after being dried, vinasse moisture content is 10-18%.
The present invention compared with prior art, have a significant effect, as can be known from the above technical solutions: the present invention is dry is to adopt first order roller drying, second, third grade of cyclone drying, in dry run, vinasse enter drying with dry gas, in flow process, vinasse fully contact with dry gas, and meanwhile, dry gas provides certain kinetic energy for vinasse, make vinasse and the collision of dry wall, a part of vinasse are pulverized, increased the heating surface area of vinasse, thereby improve drying effect.By dried vinasse, adopt pair roller roll compacting, guarantee that vinasse two-story valley hull shape shape is intact, other components are crushed by rolling, then realize husk in vinasse by vibrosieve and separate with the efficient of other components.After separating, husk separative efficiency can reach more than 95%, can make husk content in Maotai-flavor liquor vinasse be reduced to below 5% from original 30%, thereby realize the crude fiber content that reduces vinasse, increases the object of crude protein and crude fat content.
