Abstract
The utility model provides a novel raw material expander, which comprises a rack, a main motor, a reduction gearbox, a boring machine, two screws, a cutting and discharging port. The novel raw material expander is characterized in that the two isometric screws with the length-diameter ratio of 3.5:1 to 5.5:1 are arranged in parallel in the boring machine and are driven by the main motor to run in the same direction, and the boring machine is provided with a plurality of steam filling ports. Since the two screws are arranged in parallel and run in the same direction, the expander has a self-cleaning function, and blockage cannot be caused; the retention time of materials in the expander can be reduced, and the material delivering capacity of the screws can be improved; and steam is sprayed in along the material flow direction, the materials can be fully mixed with the steam, the degree of gelatinization can be increased, shearing friction can be reduced, the service life of the screws can be prolonged, and losses of substances in materials can be reduced.
Description
Technical field
The utility model relates to bulking machine, specifically is a kind of novel material bulking machine.
Background technology
In the last few years, owing to the further investigation to Animal nutrition and biotechnology, after discovery is expanded to main feedstuff such as soybean, corn, changed physical arrangement and the chemical property of each composition in the feedstuff, starch especially wherein and protein ingredient.This selection for other raw material provides more leeway, can reduce cost in large quantities and can not have influence on the quality of product.Puffing process also makes protein generation sex change, passivation many ANFs, improve the utilization rate of protein.In addition, expanding treatment has also reduced the bacterium in the raw material, mould and fungi content, has improved the health quality of feed, has improved palatability, obtains better economic and is worth.Just owing to raw material puffed series of advantages arranged, domestic the expanded of raw materials such as soybean, corn more and more paid attention to, promoted the development of domestic raw material puffed equipment widely.
Behind the raw material puffed machine of external introduction, raw material puffed machine is in China's fast development; But along with the demand of efficient aquaculture to corn, soybean puffing sharply increases, require raw material puffed machine to high yield low energy consumption and specialized direction development.But existing raw material puffed machine exists some shortcomings: the existing overwhelming majority of raw material puffed machine is single serew bulker, because primary raw materials such as corn, soybean need HTHP when expanded, need strong shearing and friction, so screw rod weares and teares especially easily.Screw slenderness ratio is generally between 5.8: 1～9: 1, because after the raw material gelatinizations such as corn, viscosity height, mobile poor has increased the probability of the stifled machine of material greatly, and same giving torn machine open behind the stifled machine and put to no little inconvenience, and increased difficulty and the expense of maintenance.Secondly raw material puffed machines such as corn, soybean yield poorly, and the energy consumption height can not satisfy the production requirement of feed factory far away, press for the novel raw material puffed machine of research like this.
Summary of the invention
The purpose of this utility model is to provide a kind of according to the deficiencies in the prior art to have from cleaning function, the novel material bulking machine that stifled machine phenomenon can not occur, this bulking machine increases screw rod to the conveying capacity of material, the mode that adopts steam to spray into along the Flow of Goods and Materials direction simultaneously, material and steam are fully mixed, improve gelatinization degree, reduce the shearing friction effect, improve the life-span of screw rod, reduce the loss of various materials in the material.
The technical solution of the utility model: described a kind of novel material bulking machine comprises frame, main motor, reduction box, machine boring, screw rod, cutting discharging opening, it is characterized in that: described screw rod is that 3.5: 1～5.5: 1 isometrical screw rod is arranged side by side in the machine boring by two draw ratios, and two screw rods are done running in the same way under the drive of main motor, be provided with a plurality of steam in the machine boring and add mouth.
The further technical scheme of the utility model: the back lash between two screw rods is 0.5～1.5mm, and every screw rod forms by single-head screw and double threaded screw alternate combinations, be single-head screw near feed end wherein, close discharge end is double threaded screw, the single-head screw total length accounts for 3/4～2/3 of total spiro rod length, and the double threaded screw total length accounts for 1/4～1/3 of total spiro rod length.
Optimal technical solution of the present utility model: being arranged on has a plurality of steam interpolation mouths all axially to become 30-60 ° of angle with the machine boring in the machine boring.
The utility model has changed the structure of traditional raw material puffed machine, and the frame mode that adopts twin-screw to turn round in the same way side by side has from cleaning function bulking machine, stifled machine phenomenon can not occur; Adopt the screw rod of short draw ratio, reduce material time of staying in bulking machine, and the isometrical screw rod of single head and the isometrical screw rod of double end combine, increase screw rod to the conveying capacity of material; Increase the steam inlet in the machine boring, can in the machine boring, increase steam, steam is sprayed into along the direction of Flow of Goods and Materials, material and steam are fully mixed, improve gelatinization degree, reduce the shearing friction effect, improve the life-span of screw rod, reduce the loss of various materials in the material simultaneously.
