Description
Technical field
The present invention relates to a kind of production technology of albumen feedstuff, add the production technology of pulp fibres particularly to a kind of Semen Maydiss,
Belong to Semen Maydiss and add pulp fibres production technical field.
Background technology
Corn starch factory adopts corn soaking, wet grinding production technology, and major product is starch, side-product have Zein powder,
Fructus Maydiss, corn fiber, Semen Maydis pulp.Corn fiber and Semen Maydis pulp are mixed together and can obtain Semen Maydiss and add pulp fibres, include rich
Rich protein, is good albumen feedstuff.
Semen Maydiss add pulp fibres be by the Semen Maydis pulp after corn soaking with broken after corn fiber combination drying and obtain
Feedstuff, because Semen Maydiss plus pulp fibres protein content are more than 18%, it has also become wide variety of one kind of Feedstuff Enterprises both at home and abroad
Novel protein feed raw material, is commonly used to Substitution for Soybean Meal, fish flour in poultry and aquatic product matched feedstuff, and can be with Direct-fed
Ruminant.
Traditional Semen Maydiss add pulp fibres production system, corn fiber are first dried to moisture below 12%, then add Semen Maydiss
Slurry drying, or be dried after fiber and Semen Maydis pulp mixing in the lump.There is following weak point in such technique：(1) corn fiber exists
It is oven-dried after being less than 12% to moisture content, a shell can be formed on surface, now be added Semen Maydis pulp, dense Semen Maydis pulp is not allowed
Easily penetrate into inside corn fiber, be simply bonded in the surface of corn fiber, make corn fiber be easy to agglomerating caking, product quality
Difference.(2) Semen Maydiss plus pulp fibres are disposably dried and put in place, steam consumption is big, and drying efficiency is low, is unfavorable for the ladder of energy
Level utilizes.(3), in order to discharge humidity as quickly as possible, the convulsion amount ratio of pipe bundle drier is larger, the aperture of fresh air air door also than
Larger so that the exhaust temperature of pipe bundle drier is low, high containing air capacity, reduce the quality of tail gas, be unfavorable for tail gas is carried out
Heat recovery.（4）Corn starch factory at present, Semen Maydis pulp all can not be all added in corn fiber, can only add 70% about
Semen Maydis pulp, remaining Semen Maydis pulp can only take out or be discharged into sewage farm.Because current technique, all Semen Maydis pulps of interpolation, 1
Energy consumption is very high, causes Semen Maydiss to add pulp fibres cost too high.The color that 2 Semen Maydiss add pulp fibres is very deep, market difficult to accept.
Content of the invention
It is an object of the invention to, overcome problems of the prior art, provide a kind of Semen Maydiss to add the production of pulp fibres
Technique, energy consumption is low, and drying efficiency is high and good product quality.
For solving above technical problem, a kind of Semen Maydiss of the present invention add the production technology of pulp fibres, include successively walking as follows
Suddenly：(1) corn starch factory corn fiber is separated into Dehydrated Corn fiber and dehydration liquid through spiral dewaterer；(2) to corn starch factory
Semen Maydis pulp carries out concentration and becomes the dense Semen Maydis pulp entrance total adding tube of dense Semen Maydis pulp, and above-mentioned Dehydrated Corn fiber enters feed spiral shell
Rotation conveyer, a part enters the first feed auger from the first discharging opening of feed conveying worm, is sent by the first feed auger
Enter the first pipe bundle drier and carry out one-level drying；(3) through the dried corn fiber of one-level from the discharging opening of the first pipe bundle drier
Discharge, returning charge ratio is controlled by the first T-piece splitting valve, the corn fiber of one-level returning charge returns to institute through the first returning charge conveying worm
State the entrance of the first feed auger, the head inlet of the corn fiber entrance discharging spiral conveyor of one-level discharging is delivered to backward
The centre exit of discharging spiral conveyor is discharged；(4) the corn fiber of one-level discharging goes out from the middle part of described discharging spiral conveyor
After mouth is discharged, deliver to the charging aperture of the first mixer through the second returning charge conveying worm；Step (2) Dehydrated Corn fiber another
Part discharges the charging aperture also into the first mixer from the second discharging opening of described feed conveying worm, and dense Semen Maydis pulp always adds
Plus the dense Semen Maydis pulp in pipe adds the charging aperture also into described first mixer for the slurry valve through first, through the first mixer mix homogeneously
Afterwards, one-level adds corn fiber entrance second feed auger of slurry, sends into the second pipe bundle drier by the second feed auger and carries out two
Level is dried；(5) the corn fiber after secondary drying is discharged from the discharging opening of the second pipe bundle drier, by the second T-piece splitting valve
Control returning charge ratio, the corn fiber of two grades of returning charges enters the anterior entrance of described discharging spiral conveyor, the jade with one-level discharging
The centre exit that rice fiber is delivered to described discharging spiral conveyor jointly backward is discharged；The corn fiber of two grades of dischargings enters institute
The rear entry stating discharging spiral conveyor is delivered to the caudal end egress discharge of described discharging spiral conveyor backward；(6) two grades go out
The corn fiber of material, after the caudal end egress of described discharging spiral conveyor is discharged, enters the lower end of the 3rd returning charge conveying worm
Entrance, and the charging aperture of the second mixer is delivered to by the 3rd returning charge conveying worm；Dense jade in the total adding tube of dense Semen Maydis pulp
Rice ＆ peanut milk through second plus starches the charging aperture also into described second mixer for the valve, after the second mixer mix homogeneously, two grades plus slurry
Corn fiber enter the 3rd feed auger, by the 3rd feed auger send into the 3rd pipe bundle drier carry out three-stage drying；(7) warp
Corn fiber after three-stage drying is discharged from the discharging opening of the 3rd pipe bundle drier, controls returning charge ratio by the 3rd T-piece splitting valve,
The corn fiber of three-level returning charge enters the second charging aperture of described 3rd returning charge conveying worm, by described 3rd returning charge spiral transferring
Machine is sent to return to the charging aperture of described second mixer；The Semen Maydiss of three-level discharging add pulp fibres and arrange from Semen Maydiss plus pulp fibres finished product mouth
Go out.
With respect to prior art, the present invention achieves following beneficial effect：1. corn starch factory corn fiber is first separated into
Dehydrated Corn fiber and dehydration liquid, the water content of Dehydrated Corn fiber is 61～63%, is introduced into the first pipe bundle drier and carries out
One-level is dried, the discharging moisture control that one-level is dried 15～30%, then using the dense Semen Maydis pulp being concentrated by dehydration liquid
Carry out once plus slurry, and pass through the first mixer mix homogeneously, enter back into and carry out secondary drying into the second pipe bundle drier, two
The discharging moisture control that level is dried 15～30%, then carries out secondary plus slurry using dense Semen Maydis pulp, and mixes by second
Machine mix homogeneously, enters back into and carries out three-stage drying into the 3rd pipe bundle drier, the discharging moisture control of three-stage drying 10～
12%.2., compared with the disposable drying in parallel using multiple stage pipe bundle drier of traditional technique, the present invention adopts more than three-level to go here and there
