Abstract
The present invention provides gallnut processing apparatus for producing tannic acid, and aims at breaking compact structure of gallnut for further processing at normal temperature. The gallnut processing apparatus features that it has one gallnut puffing device in the discharge port to break the compact structure of gallnut, and the puffed gallnut is leached at normal temperature to obtain tannic acid without blocking the leaching out of gum, pectin and other non-tannin matters. The present invention can raise the quality of obtained tannic acid product, and less technological steps.
Description
Technical field:
The present invention relates to a kind of Turkey-galls processing units that utilizes in the Turkey-galls manufacturing Weibull.
Background technology:
Turkey-galls contains the Weibull about 60%, about 14% moisture, about 26% natural gum, pectin, Mierocrystalline cellulose, and gallic acid etc.The Turkey-galls compact structure is not soluble in water, and the easy oxidation of Weibull darkens, and the slow hydrolysis of its aqueous solution generates gallic acid under the condition of high temperature.And non-tannin substances such as the natural gum that contains in the Turkey-galls when high-temp extracting, pectin also are extracted in the vat liquor simultaneously, thereby the Weibull quality is reduced.The existing production process of tannic acid of enterprise all be with Turkey-galls through screening, broken back lixiviate, concentrate, freezing sedimentation, ethyl acetate extraction, secondary concentration, drying, finished product; In order to overcome the problem of Turkey-galls compact structure, in the lixiviate operation, adopt 65 ℃～85 ℃ adverse current lixiviate Turkey-galls of high temperature to make vat liquor, take 44～48 hours; And in order to remove impurity, just after high-temp extracting, must can be effective through freezing, sedimentation, ethyl acetate extraction decolouring.Its explained hereafter cycle is long, and product quality is relatively poor, expends a large amount of energy and ethyl acetate simultaneously.
Summary of the invention:
The purpose of this invention is to provide a kind of Turkey-galls processing units that uses when utilizing Turkey-galls to make Weibull, solve the Turkey-galls compact structure, in the lixiviate operation, need to adopt 65 ℃～85 ℃ adverse current lixiviate Turkey-galls of high temperature to make the problem of vat liquor, the Turkey-galls processing units that the present invention is a kind of to be used when utilizing Turkey-galls to make Weibull is characterized in that, the present invention is that the discharge port at gallic disintegrating apparatus is connecting a puffing equipment, described bulking equipment can be the dry method bulking machine that field of feed processing is used, particle after the Turkey-galls fragmentation is advanced to pressure space by the extrusion spiral group from the material feeding box of bulking machine, behind the one-level steam binding, obtained preliminary extruding, heat, after this whenever by the one-level steam binding, all be subjected to enhanced extruding gradually and heat, until extruding from the discharging die head.The present invention by bulking equipment to Turkey-galls particulate expanding processing, destroyed the problem of Turkey-galls compact structure, make the Turkey-galls structure after expanded bulk, when lixiviate, can in normal temperature environment, directly obtain Weibull, the hydrolysis of Weibull and oxidizing reaction when having avoided high-temp extracting, hinder non-tannin substances leachings such as natural gum, pectin, thereby realized improving the purpose of Weibull quality; Technologies such as freezing, sedimentation, ethyl acetate extraction, decolouring have been reduced.
Embodiment:
The present invention is that the discharge port at gallic disintegrating apparatus is connecting a P400G type dry method bulking machine, particle after the Turkey-galls fragmentation is advanced to the pressure space standard by the extrusion spiral group from the material feeding box of bulking machine, behind the one-level steam binding, obtain preliminary extruding, heated, after this whenever passed through the one-level steam binding, all be subjected to enhanced extruding gradually and heat, until extruding from the discharging die head.
Claims (1)
1, the Turkey-galls processing units that the present invention is a kind of uses when utilizing Turkey-galls to make Weibull is characterized in that, the present invention is that the discharge port at gallic disintegrating apparatus is connecting a puffing equipment, particle after the described Turkey-galls fragmentation is advanced to pressure space by the extrusion spiral group from the material feeding box of bulking machine, behind the one-level steam binding, obtain preliminary extruding, heated, after this whenever passed through the one-level steam binding, all be subjected to enhanced extruding gradually and heat, until extruding from the discharging die head.
