Description
Technical Field
The invention relates to the technical field of biological fermentation, in particular to a delinting machine and a delinting method, which are suitable for producing cottonseed protein special for fermentation by efficiently removing the delinting with dephenolized cottonseed protein as a raw material.
Background
China is a world major medicine raw material medicine production country, and raw material medicine products such as antibiotics, amino acids, vitamins and the like occupy an important position in world markets every year. The annual production total amount of antibiotic medicines in China is about 5 ten thousand tons, the production of the antibiotic raw medicines mostly adopts industrial fermentation production, and the total required amount of a required culture medium is more than 20 ten thousand tons. The yield of three large fermentation products in China is about 100 ten thousand tons, and enzyme preparations such as amylase, protease, cellulase, diastase and the like need a large amount of culture medium for fermentation production. The amino acid productivity is continuously enlarged, and the demand on the culture medium is rapidly increased.
The modernization of the fermentation industry in China (such as the application of advanced fermentation complete equipment, separation and purification equipment and the like) has been greatly advanced forward and is close to the advanced level in the world. In contrast, the production level of organic nitrogen source culture medium for industrial fermentation is far behind developed countries, and has become one of the limiting factors for the long-term stable development of the microbial fermentation industry in China. The dephenolized cottonseed protein is a high-quality raw material for producing a culture medium, and is particularly suitable for a specific fermentation strain. But the residual cotton wool inhibits the growth of the biological thalli in the fermentation production and reduces the fermentation titer level; in addition, when the fermentation product is subjected to membrane filtration post-treatment, membrane pores are blocked, the production efficiency is reduced, and loss is caused. The cotton seed protein is necessary to be subjected to lint removal treatment, and parameters such as time, temperature and the like of fermentation production are strictly controlled, so that if the fineness of a culture medium product is consistent and is consistent with the fermentation period, the culture medium product can be used and exhausted most reasonably in the fermentation process, fermentation waste residues (water) are greatly reduced while the unit consumption of the culture medium is reduced, clean production is facilitated, and three-waste treatment and environmental protection are facilitated. In addition, the low-temperature crushing can effectively prevent the protein from deforming and the nutrition from being lost. Therefore, the cotton seed protein is used as a raw material to produce the culture medium, and the lint removal and the crushing are key technologies.
However, the prior art lint removing device and method have the following defects: the residual quantity of the short velvet can only reach about 0.5 percent, and the production requirement can not be met; the equipment structure is complicated, and the energy consumption is high. For example, Chinese patent application 200610145399.8 discloses a cottonseed kernel with low lint content, its production method and device, its patent publication No. CN1948560A, published as 2007-04-18. The production method comprises the steps of adding a cottonseed kernel material containing cotton linters onto a flock flow guide plate, enabling the flock flow guide plate to do plane rotation movement, enabling the rotation speed to be 100-150 revolutions per minute, enabling the rotation radius to be 30-90 mm, enabling the inclination angle of the flock flow guide plate and the horizontal plane to be 0-7 degrees, enabling the cotton linters dispersed in the cottonseed kernel to gradually form flocks and be removed, and the production device comprises a rack, a sieve bed and a driving mechanism enabling the sieve bed to do plane rotation movement, wherein the sieve bed is internally provided with the flock flow guide plate, and sieve plates are arranged on the upper surface and the lower surface of the flock flow guide plate.
The application adds the cottonseed kernel material containing the cotton linters to the flock guide plate, and a barrier is arranged on the flock guide plate, the barrier is a flock partition plate and/or flock protrusions, and the barrier plays a role in reinforcing the flock. In the application, after the bulk cotton velvet is gathered on the bulk cotton velvet guide plate, the bulk cotton velvet is removed by a wind separation method so as to be separated from the cottonseed kernels after the velvet is removed. This mode of getting rid of bulk cotton linter from the cottonseed kernel need adjust and control wind-force, need get rid of bulk cotton linter totally promptly, will remain the cottonseed kernel after removing the fine hair again, and this operation degree of difficulty is big, and has the loss to remove the cottonseed kernel after the fine hair, reduces production efficiency's risk.
