Description

Technical Field

[0001] The invention relates to the technical field of collagen peptide preparation, and in particular to a separation and purification device and process for preparing liquid collagen peptide. Background Art

[0002] Collagen peptide oral liquid is a functional food with collagen as its main ingredient. It is taken orally to supplement the collagen needed by the human body. Existing collagen peptide oral liquids are produced by spray-drying collagen peptides into powders, which need to be re-dissolved in water during the production of oral liquids. This process consumes a lot of manpower and material resources. High-concentration large-package collagen peptides reduce the spray drying, water addition, heating and re-dissolution steps, reduce energy consumption and environmental pollution, and avoid the impact of multiple heating on the taste, smell, color and physiological activity of collagen peptides.

[0003] Among them, high-concentration collagen peptides refer to collagen products with smaller molecular weight and higher concentration obtained after collagen has been processed by processes such as hydrolysis, separation, and purification. In order to improve the purity and concentration of collagen peptides, it is generally necessary to filter and separate the collagen peptide raw material liquid. In this process, a multi-stage filtration mechanism is usually used to filter the collagen peptide raw material liquid. When the existing filtration mechanism is filtering, impurities will accumulate on the surface of the filter mesh during long-term use, which will affect the filtration of the raw material liquid and even cause blockage. Therefore, it is necessary to manually disassemble and replace the filtration mechanism. During this process, the preparation of collagen peptides needs to be stopped, and the device needs to be re-sterilized during the replacement process, which consumes a lot of time and makes the preparation efficiency of the collagen peptide liquid low, which is not conducive to the preparation of large packages of collagen peptides.

A hydraulic rod can be fixedly arranged on the sealing plate 41, and a hydraulic cavity is provided in the sealing groove. The hydraulic rod is sealingly and slidably connected with the hydraulic cavity. The sliding of the sealing plate 41 is controlled by filling liquid into the hydraulic cavity.

That is, when the driving plate 51 drives the filter assembly 3 to slide out of the filter housing 1, the sealing rod passively slides along the sealing cavity, so that the inclined filter assembly 3 slides out of the filter housing 1 smoothly. After the filter assembly 3 slides out of the filter housing, the sealing rod is actively driven to slide, so that the sliding plate 521 can drive the deflection frame 32 to deflect, so that the filter seat 33 and the filter screen 34 are in a horizontal position for easy cleaning.

Sterilize the entire device, then use the driving component (5) to drive the plurality of filter components (3) in one of the cleaning shells (2) to slide into the filter housing (1), and at the same time drive the guide component (4) to slide, so that the plurality of guide plates (43) and the plurality of filter components (3) are arranged in an inclined and staggered manner; S2, feeding the collagen peptide raw material liquid from the feed pipe into the filter housing (1), and filtering the raw material liquid through the plurality of filter components (3); S3, the filtered raw material liquid enters the buffer chamber, the clarity of the raw material liquid in the buffer chamber is observed or the raw material liquid in the buffer chamber is detected by a particle detector to determine whether the raw material liquid needs to be circulated and filtered; S4, when it is necessary to replace and clean the filter assembly (3), the supply of raw material liquid is temporarily stopped and the driving assembly (5) is used to drive the plurality of filter assemblies (3) to slide into the cleaning shell (2), and at the same time the guide assembly (4) is driven to slide and the plurality of filter assemblies (3) in another cleaning shell (2) are slid into the filter housing (1), at which time the plurality of guide plates (43) and the plurality of filter assemblies (3) are arranged in an inclined and staggered manner, and then the raw material liquid is re-supplied; S5, after the filter assembly (3) enters the cleaning shell (2), the sliding member (52) is driven to slide, so that the sliding member (52) drives the deflection frame (32) to rotate to a horizontal position, and then the driving rod (522) is driven to slide back and forth, so that the gear 2 (534) rotates back and forth under the meshing action of the teeth (523) and drives the filter seat (33) to rotate, and then the cleaning agent is sprayed by the spray head (22), and at the same time, the spray rod (21) is rotated to perform all-round flushing of the filter screen (34); S6, after the flushing is completed, the driving rod (522) is continuously driven back and forth, so that the filter seat (33) drives the filter screen (34) to rotate back and forth, the cleaning liquid is thrown off, and the filter assembly (3) is dried by a drying mechanism; S7, alternately replacing the filter components (3) in the filter housing (1) to filter the raw material liquid, and cleaning the replaced filter components (3) until all the raw material liquid has been filtered.
