Description

Technical Field

[0001] This utility model relates to the field of concentration equipment technology, and in particular to a multi-effect concentration device for high-purity collagen tripeptide solution. Background Technology

[0002] Collagen tripeptide is the smallest and most stable structural unit in collagen. It is a tripeptide containing glycine, proline (or hydroxyproline) and one other amino acid.

[0003] Collagen tripeptides are generally obtained from animal connective tissue through extraction, enzymatic hydrolysis, and concentration. Due to their small molecular weight and high activity, small collagen tripeptides have more exposed carboxyl sites, making them more susceptible to degradation and decomposition by high temperatures and acids / alkalis, which also alters their purity, color, and odor.

[0004] Existing concentration devices, such as the collagen tripeptide concentration device disclosed in patent CN221601410U, utilize a heating plate to heat the collagen tripeptide stock solution inside the tank, causing the water to evaporate and obtaining a concentrated collagen tripeptide solution. Simultaneously, a stirring shaft agitates the material. However, because the material is concentrated within the tank, the heating surface area is limited, resulting in extremely slow water evaporation, low concentration efficiency, and poor purity of the obtained concentrate. Furthermore, the stirring process can damage the collagen tripeptides, altering their physicochemical properties and consequently affecting the product's purity, color, odor, and activity.

[0005] Therefore, existing collagen tripeptide concentration devices need to be improved. Utility Model Content

[0036] The working principle and material path of this utility model are as follows:

[0037] 1. Preheating: The material first passes through the tube layer of the triple-effect evaporator 5, the tube layer of the double-effect evaporator 4, and the tube layer of the single-effect evaporator 3 before entering the preheater 2 for preheating, thereby increasing the temperature of the raw material liquid and reducing the consumption of heating steam.

[0038] II. First-Effect Evaporation and Concentration: The preheated raw material liquid enters the first-effect evaporator 3. The raw material liquid is evenly distributed to the tube wall of the tube layer by the distributor at the top of the first-effect evaporator 3, where it exchanges heat with the heating steam in the tube layer. The raw material liquid flows to the bottom of the first-effect evaporator 3, where the first material pump 8 transports the raw material liquid back to the distributor at the top of the first-effect evaporator 3 and distributes it to the tube wall of the tube layer for evaporation and concentration again. This causes some of the water in the raw material liquid to evaporate in the first gas-liquid separator 11. The generated secondary steam enters the second-effect evaporator 4 as heating steam, while the primary concentrate at the bottom of the first gas-liquid separator 11 is transported to the second-effect evaporator 4 by the fourth material pump 12.

[0039] 3. Second-Effect Evaporation and Concentration: The primary concentrate from the first-effect evaporator 3 is evenly distributed onto the tube wall of the tube layer by the distributor at the top of the second-effect evaporator 4, where it exchanges heat with the heating steam in the tube layer. The primary concentrate flows to the bottom of the second-effect evaporator 4, where the second material pump 9 transports it back to the distributor at the top of the second-effect evaporator 4 and distributes it onto the tube wall of the tube layer for another evaporation and concentration process. This causes some of the water in the primary concentrate to evaporate in the second gas-liquid separator 13, and the resulting secondary steam enters the third-effect evaporator 5 as heating steam. Meanwhile, the secondary concentrate at the bottom of the second gas-liquid separator 13 is transported to the third-effect evaporator 5 by the fifth material pump 14.

[0040] IV. Triple-Effect Evaporation and Concentration: The secondary concentrate from the second-effect evaporator 4 is evenly distributed onto the tube wall of the tube layer by the distributor at the top of the triple-effect evaporator 5, where it exchanges heat with the heating steam in the tube layer. The secondary concentrate flows to the bottom of the triple-effect evaporator 5, where the third material pump 10 transports it back to the distributor at the top of the triple-effect evaporator 5 and distributes it onto the tube wall of the tube layer for another evaporation and concentration process. Some of the water in the secondary concentrate evaporates in the third gas-liquid separator 15, and the generated secondary steam enters the condenser 6 for cooling. The bottom of the third gas-liquid separator 15 forms a tertiary concentrate, which is then discharged by the sixth material pump 16.

[0041] V. Condensation: The secondary steam generated by the triple-effect evaporator 5 enters the condenser 6 and is condensed into water, which is then discharged from the bottom of the condenser 6 by the drain pump 17.

[0042] VI. Non-condensable gas discharge: During the evaporation process, some non-condensable gases will be generated. These non-condensable gases will be discharged through the exhaust port at the top of the condenser 6.

[0043] This invention utilizes three evaporators connected in series. On one hand, it evaporates a large amount of water from the raw material to form a concentrated liquid, thereby improving the material concentration efficiency. On the other hand, it utilizes the heat of the heating steam multiple times, thereby improving the utilization rate of thermal energy and reducing energy consumption. Furthermore, the material does not need to be stirred during the concentration process, avoiding the destruction of collagen tripeptide molecules and thus maintaining the stability of the chemical and physical properties of collagen tripeptides.

Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
