Production equipment for extracting cotton protein from cottonseed meal

Abstract

The invention relates to production equipment for extracting cotton protein from cottonseed meal. The production equipment comprises a feeding mechanism, a particle crashing mechanism, a midway feed bin, an airlock, a sieving mechanism and a material receiving mechanism, wherein an air outlet of the airlock is communicated with the sieving mechanism; the particle crashing mechanism is an airflow scroll type crashing mechanism, and is provided with an air inlet chamber, a crashing chamber and a grading chamber which are communicated with each another; and the airflow scroll type crashing mechanism comprises a feeding device communicated with the crashing chamber, a crashing device arranged inside the crashing chamber, a grading device arranged inside the grading chamber, as well as a first driving device and a second driving device which respectively drive the crashing device and the grading device. According to the production equipment, cottonseed meal particles with different sizes can be crashed, and the finenesses of the cottonseed meal particles after being crashed are uniform, so that the phenomenon that the compositions of the cotton protein are damaged is reduced, the working requirement of the sieving mechanism is reduced at the same time, and the equipment cost is saved.

Description

technical field [0001] The invention relates to a production equipment for extracting cotton protein from cotton meal. Background technique [0002] As we all know, the pre-pressed cake obtained after cottonseed is pressed, and then more than 95% of the residual oil in it is separated through the leaching process, and a light yellow or reddish granular product is obtained, commonly known as cotton meal, which contains crude oil The protein can reach more than 40%, and it is also the main raw material for making feed. At the same time, it is widely used in the production of medicines at home and abroad, such as spiramycin. [0003] At present, the production equipment used to extract cotton protein from cotton meal mainly includes a particle crushing mechanism, a screening mechanism, and a conveying mechanism. However, due to the difference in the particle size of cotton meal, the abrasion resistance of crude fiber and cotton kernel is also different, which makes it difficu...

AI Technical Summary

Problems solved by technology

[0003] At present, the production equipment used to extract cotton protein from cotton meal mainly includes particle crushing mechanism, screening mechanism and conveying mechanism, and the quality of cotton protein depends on Particle crushing mechanism, the general particle crushing mechanism adopts the grinding method to crush the particles. However, due to the difference in the particle size of the cotton meal, the wear resistance of the coarse fiber and the cotton kernel is also different, which makes it difficult to control the grinding force. Large, destroys the tissue composition of cotton protein, directly affects the quality of cotton protein, and the grinding force is too small, directly reduces the extraction amount of cotton protein, and at the same time has higher requirements for the screening mechanism, resulting in higher production costs
