Biological feed extruder

Abstract

The invention relates to a biological feed extruder which comprises a base, an extruder body, an extruding nozzle, a rotary shaft, an auger blade, a charging pipeline I, a first motor, a charging pipeline II, a push plate, a ball nut pair, a second motor, a lead screw and a charging hole, wherein the extruding nozzle is formed in the left end of the extruder body; the charging pipeline I is arranged on the right side of the extruder body on the upper end surface of the base; the right end of the rotary shaft is fixedly connected to the output end of the first motor; the charging hole is formedin the left end of the charging pipeline II; the push plate is slidably connected in the charging pipeline II; the ball nut pair is fixedly arranged on the top end in the charging pipeline II; the lead screw is assembled in the ball nut pair; the lower end of the lead screw is in contact with the push plate; and the top end of the lead screw is fixedly connected to the output end of the second motor. According to the design, the biological feed is compressed by means of electric energy and then is fed into the extruder body to be extruded, and meanwhile, the feed needs not to be charged manually, so that the extruding efficiency is improved and the extruding effect is enhanced.

Description

Technical field [0001] The invention relates to the field of biological feed processing equipment, in particular to a biological feed extruder. Background technique [0002] The concept of biological feed has only been proposed in the past ten years, and the understanding of its definition and connotation is constantly changing with the development of science and practice. The biological feed generally refers to new feed resources and feed additives developed by microbial engineering fermentation with feed and feed additives as the object, using high-tech such as genetic engineering, protein engineering, and fermentation engineering as means. There are dozens of varieties of biological feed products developed worldwide, and it has become a larger industry, mainly including feed enzyme preparations, feed amino acids and vitamins, probiotics (directly fed to microorganisms), feed oligosaccharides, Natural plant extracts, biologically active oligopeptides, biological pigments for f...

Problems solved by technology

[0003] Biological feed often needs to be extruded, but in the prior art, before it is put into the extruder, the biological feed needs to be manually compressed, and then put into the extruder, the expansion efficiency is low, and the expansion effect is poor. There is an urgent need for a biological feed extruder to solve the above problems
