The filtrate obtained is ultrafiltered through 10000Da (molecular weight) and 3000Da (molecular weight) ultrafiltration membranes in turn, and the filtrate obtained is concentrated and dried to obtain donkey-hide gelatin peptide; the degreasing and decolorization is to add activated carbon to remove oil and pigment in the donkey-hide gelatin hydrolyzate; the ultrafiltration membrane used in the ultrafiltration is the ultrafiltration membrane of Beijing Xubang Membrane Equipment Co., Ltd.; the drying is spray drying carried out under the conditions of an inlet temperature of 220°C and an outlet temperature of 88°C. In the production process of donkey-hide gelatin peptide, the hydrolyzate obtained after enzymatic hydrolysis needs to be filtered, impurities removed and purified. In the prior art, centrifugal filtration devices are mostly used to perform preliminary filtration and purification on the hydrolyzate. Although the centrifugal filtration device has a good filtration effect, in order to avoid the filter holes of the centrifugal cylinder being blocked and affecting the yield of donkey-hide gelatin peptide, usually only a small amount of hydrolyzate containing donkey-hide gelatin peptide obtained after enzymatic hydrolysis is centrifuged and filtered for purification at a time, which results in low filtration efficiency. In view of this, a filtration mechanism for donkey-hide gelatin peptide production that can improve filtration efficiency is specially proposed. Summary of the invention

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model. Example

[0019] Reference Figure 1-Figure 3A filtering mechanism for donkey-hide gelatin production includes a shell 1, a filter cartridge 2 is rotatably connected in the shell 1, a first motor 201 is fixedly connected to the bottom of the shell 1, and the output end of the first motor 201 is fixedly connected to the filter cartridge 2, and also includes: an upper cover 3, which covers the opening at the upper end of the shell 1; a feed pipe 301 for adding materials to the filter cartridge 2 is fixedly connected to the upper cover 3; a mounting rod 303 is connected to the lower end of the upper cover 3 and is located in the filter cartridge 2; an inclined plate 304 is staggered and symmetrically arranged in the filter cartridge 2, and is slidably attached to the inner wall of the filter cartridge 2, and the mounting rod 303 and the inclined plate 304 are fixedly connected by a connecting rod; a discharge pipe 103 is symmetrically fixedly connected to both sides of the lower end of the shell 1 and is connected to the shell 1.

[0020] During the production process of donkey-hide gelatin peptide, the hydrolyzate obtained after enzymatic hydrolysis is a suspension. The donkey-hide gelatin peptide obtained after enzymatic hydrolysis is suspended in the enzymatic hydrolyzate. The suspension has the characteristics of highly dispersed materials, relatively viscous liquid phase, fine solid particles, and strong compressibility. Even after centrifugation, the liquid phase containing donkey-hide gelatin peptide still has a relatively high viscosity, which is a typical difficult-to-filter material.

[0021] When it is necessary to filter and purify the hydrolyzate obtained after enzymolysis, the hydrolyzate obtained after enzymolysis can be transported into the filter cartridge 2 through the feed pipe 301. When the donkey-hide gelatin peptide enters the filter cartridge 2, part of the liquid phase containing the donkey-hide gelatin peptide will flow out of the filter cartridge 2 through the filter holes of the filter cartridge 2 and be discharged from the device through the discharge pipe 103, while part of the viscous system containing part of the donkey-hide gelatin peptide liquid and the solid phase will remain in the filter cartridge 2. At this time, the first motor 201 can be started, and the first motor 201 will drive the filter cartridge 2 to rotate rapidly in the housing 1, and then the liquid phase in the filter cartridge 2 will be thrown out of the filter cartridge 2 through the filter holes under the action of centrifugal force. Since the solid phase will be thrown out of the filter cartridge 2 under the action of centrifugal force, The viscous system attached to the filter holes on the side wall of the filter cartridge 2, and therefore, the viscous system containing part of the donkey-hide gelatin peptide liquid and the solid phase will be intercepted in the filter cartridge 2 under the obstruction of the solid phase. By setting the inclined plate 304, the viscous system attached to the wall of the filter cartridge 2 under the action of centrifugal force can be scraped off together, and guided to the middle of the filter cartridge 2 under the guidance of the inclined plate 304, and then the liquid phase in the scraped off viscous system will be thrown onto the filter cartridge 2 again under the action of centrifugal force, and discharged from the filter cartridge 2 through the filter holes. By repeating this process, the liquid phase can be fully centrifuged out of the filter cartridge 2, so that only the solid phase remains in the filter cartridge 2, which effectively improves the efficiency of centrifugal filtration of the hydrolyzate containing donkey-hide gelatin peptide obtained after enzymatic hydrolysis. Example

[0022] Reference Figure 1-Figure 3, a filtering mechanism for producing donkey-hide gelatin peptide, which is basically the same as Example 1, and further includes: a mounting rod 303 is rotatably connected to an upper cover 3, a second motor 302 is fixedly connected to the upper cover 3, and an upper end of the mounting rod 303 is fixedly connected to an output end of the second motor 302. When the first motor 201 drives the filter cartridge 2 to rotate rapidly, the second motor 302 can be started at this time, so that the second motor 302 drives the inclined plate 304 to rotate in the opposite direction to the filter cartridge 2 through the mounting rod 303, and then under the action of centrifugal force, the viscous system attached to the inner wall of the filter cartridge 2 will be quickly scraped off from the filter cartridge 2 under the action of the filter cartridge 2 and the inclined plate 304 rotating in the opposite direction, and gather along the inclined surface of the inclined plate 304 to the middle of the filter cartridge 2, and then the liquid phase in the scraped viscous system will be thrown onto the inner wall of the filter cartridge 2 again under the action of centrifugal force, thereby repeatedly filtering the liquid phase more fully and quickly, and preventing the filter holes of the filter cartridge 2 from being blocked and affecting the passage of the liquid phase containing donkey-hide gelatin peptide.

[0023] The first scraper 305 is symmetrically fixedly connected to both sides of the mounting rod 303 through a connecting rod. The first scraper 305 slides against the inner wall of the shell 1. Through the arrangement of the first scraper 305, when the filter cartridge 2 rotates rapidly, the liquid phase in the viscous system is thrown out of the filter cartridge 2 under the action of centrifugal force. At this time, the liquid phase containing donkey-hide gelatin peptides will be thrown onto the inner wall of the shell 1 under the action of centrifugal force. At this time, the rotating first scraper 305 can scrape off the liquid phase containing donkey-hide gelatin peptides attached to the inner wall of the shell 1, so that the liquid phase containing donkey-hide gelatin peptides can be discharged through the discharge pipe, thereby improving the collection efficiency of the filtered liquid phase containing donkey-hide gelatin peptides.

[0024] A roller 306 is installed at the lower end of the first scraper 305 through a support rod, and the roller 306 is rollingly connected to the outer wall of the filter cartridge 2. The setting of the roller 306 can not only improve the tightness of the first scraper 305 and the inner wall of the shell 1, thereby improving the scraping effect of the liquid phase containing donkey-hide gelatin attached to the inner wall of the shell 1, but also play a certain limiting effect on the filter cartridge 2, thereby improving the stability of the filter cartridge 2 when rotating.

[0025] A circle of annular grooves is provided at the inner lower end of the shell 1, and the discharge pipe 103 is connected to the annular groove. Two second scrapers 102 are symmetrically slidably connected in the annular groove. The two second scrapers 102 are fixedly connected to the lower ends of the adjacent first scrapers 305. When the liquid phase containing donkey-hide gelatin peptides centrifuged flows into the annular groove along the inner wall, the rotating first scraper 305 will drive the second scraper 102 to rotate in the annular groove, so that the filtered liquid phase containing donkey-hide gelatin peptides can be scraped from the discharge pipe 103, thereby facilitating the rapid discharge of the liquid phase containing donkey-hide gelatin peptides.

[0026] A plurality of arc grooves are provided at equal intervals on the circumference at the lower end of the filter cartridge 2 inside the shell 1, and a ball 101 is movably connected in the arc groove. The ball 101 rolls against the bottom of the filter cartridge 2. The arrangement of the ball 101 can support the filter cartridge 2, thereby facilitating the filter cartridge 2 to be more stable during rotation, and preventing the liquid phase containing donkey-hide gelatin from being thrown out under the action of centrifugal force due to the tilt of the filter cartridge 2.
