Description

Technical Field

[0001] This utility model relates to the field of collagen production technology, and in particular to a collagen plate evaporation and concentration device. Background Technology

[0002] In existing technologies, collagen is a structural protein widely found in human tissues such as skin, bones, muscles, blood vessels, ligaments, and cornea. It is an important component for maintaining skin elasticity, strength, and anti-aging. It helps maintain skin firmness and smoothness and also plays a role in wound healing, joint health, and muscle repair.

[0003] However, the above technical solutions still have the following problems due to the lack of control during collagen production: In the collagen production process, it is necessary to concentrate the low-concentration collagen solution to a high concentration to facilitate subsequent drying to obtain collagen products. Evaporation is a high-energy-consuming process unit. Generally, collagen concentration is carried out by thin-film scraper evaporation or TVR evaporation. These evaporation methods have insufficient steam recovery and high power consumption, resulting in high collagen production costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that use thin-film scraper evaporation or TVR evaporation for collagen concentration. These evaporation methods have insufficient steam recovery and high power consumption, resulting in high collagen production costs. Therefore, this invention proposes a collagen plate evaporation and concentration device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A collagen plate-type evaporation and concentration device includes a feed balance tank and a non-condensable gas condensate storage tank. The device also includes: The system includes a feeding unit, an evaporation unit, a discharging unit, a steam unit, a vacuum unit, and a condensate unit. The evaporation unit and the feeding unit are connected by pipes. The steam unit is connected to the feeding unit and the evaporation unit by valves. The vacuum unit is connected to the steam unit and the non-condensable gas condensate storage tank by pipes. The condensate unit is connected to the steam unit and the non-condensable gas condensate storage tank.

[0006] In a preferred embodiment of this utility model, the feeding unit includes a feeding pump and a condensate plate preheater. The feeding pump is connected to a feeding balance tank, and the condensate plate preheater is connected to the feeding pump.

[0007] In a preferred embodiment of this utility model, the evaporation unit includes a plate evaporator, a separator, and a circulating pump. The separator is connected to the plate evaporator, and the circulating pump is connected to the separator.

[0008] In a preferred embodiment of this utility model, the steam unit includes a secondary gas-liquid separator, a steam compressor, and a condensate tank. The steam compressor is connected to the secondary gas-liquid separator, and the condensate tank is connected to the steam compressor.

[0009] In a preferred embodiment of this utility model, the vacuum unit includes a non-condensable plate condenser and a vacuum pump. The non-condensable plate condenser is connected to a non-condensable condensate storage tank, and the vacuum pump is connected to the non-condensable plate condenser.

[0010] In a preferred embodiment of this utility model, the condensate unit includes a condensate pump and a non-condensable gas condensate pump, and the condensate pump and the non-condensable gas condensate pump are connected to a condensate plate preheater. Beneficial effects

[0011] This invention employs a specially designed low-resistance corrugated rising film plate evaporator, which ensures uniform medium distribution, low resistance, high efficiency, large heat transfer coefficient, small heat exchange area, low equipment height, and small footprint. Furthermore, its detachable design facilitates easy inspection and maintenance. Compared to traditional evaporation and concentration systems, the circulating pump head is reduced by 50-70%, and the circulating pump PO5 power is reduced by 50-60%, resulting in significant energy savings. The footprint is also reduced by 30-40%.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0016] Reference Figure 1A collagen plate evaporation and concentration device includes a feed balance tank 1 and a non-condensable gas condensate storage tank 2. The device also includes: The unit includes a feeding unit, an evaporation unit, a discharge unit, a steam unit, a vacuum unit, and a condensate unit. The evaporation unit and the feeding unit are connected by pipes. The steam unit is connected to the feeding unit and the evaporation unit by valves. The vacuum unit is connected to the steam unit and the non-condensable gas condensate storage tank 2 by pipes. The condensate unit is connected to the steam unit and the non-condensable gas condensate storage tank 2.

[0017] With the above structure, this application can achieve a highly efficient collagen solution concentration process, improve the system's working efficiency, reduce energy consumption, and effectively improve the quality and yield of concentrated collagen by controlling the working status of each part of the system through multiple heat exchanges and precise control.

[0018] As a preferred embodiment of this utility model, the feeding unit includes a feeding pump 9 and a condensate plate preheater 6. The feeding pump 9 is connected to the feeding balance tank 1, and the condensate plate preheater 6 is connected to the feeding pump 9. Through the combination of the feeding pump 9 and the condensate plate preheater 6, the collagen solution is ensured to receive sufficient heat exchange preheating before entering the evaporation unit. This not only improves the temperature rise efficiency of the collagen solution, but also significantly reduces the energy consumption during the evaporation process, thereby reducing the overall production cost.

[0019] As a preferred embodiment of this utility model, the evaporation unit includes a plate evaporator 8, a separator 4, and a circulating pump 13. The separator 4 is connected to the plate evaporator 8, and the circulating pump 13 is connected to the separator 4. The combination of the plate evaporator 8 and the separator 4 greatly improves the heat exchange efficiency between the collagen solution and the heating steam. With the cooperation of the circulating pump 13, the reflux system of the concentrate makes the evaporation and concentration process of the material more stable and enables the efficient recovery of the collagen solution in the system, further improving the overall production efficiency.

[0020] As a preferred embodiment of this utility model, the steam unit includes a secondary gas-liquid separator 5, a steam compressor 14, and a condensate tank 3. The steam compressor 14 is connected to the secondary gas-liquid separator 5, and the condensate tank 3 is connected to the steam compressor 14. This can effectively separate and recover moisture from the secondary steam, and increase the temperature and pressure of the secondary steam through the steam compressor 14. After compression, the steam enters the plate evaporator 8 as a heat source, thereby further improving the thermal efficiency of the system and reducing dependence on external energy.

[0021] As a preferred embodiment of this utility model, the vacuum unit includes a non-condensable gas plate condenser 7 and a vacuum pump 11. The non-condensable gas plate condenser 7 is connected to the non-condensable gas condensate storage tank 2, and the vacuum pump 11 is connected to the non-condensable gas plate condenser 7. The vacuum unit ensures that the system is always in a good vacuum environment during the evaporation process. By precisely controlling the extraction of non-condensable gas, the vacuum degree is stably regulated, thereby effectively improving the evaporation efficiency of the collagen solution and reducing energy loss caused by non-condensable gas, further improving the overall efficiency of the system.

[0022] As a preferred embodiment of this utility model, the condensate unit includes a condensate pump 12 and a non-condensable gas condensate pump 10. The condensate pump 12 and the non-condensable gas condensate pump 10 are connected to the condensate plate preheater 6. The condensate unit effectively realizes the recovery and recycling of condensate. Through the condensate pump 12 and the non-condensable gas condensate pump 10, the condensate can be effectively transported to the condensate plate preheater 6 for heat exchange again, reducing the energy consumption of the system. The non-condensable gas removal system ensures the timely treatment of non-condensable gas during the evaporation process, ensuring the stability and safety of the equipment operation.

[0023] The working principle of this invention is as follows: Collagen solution is fed from the feed balance tank 1 to the condensate plate preheater 6 via the feed pump 9. After multi-stage heat exchange and temperature rise, it enters the plate evaporator 8. The heat source is the condensate generated by the evaporation system. The preheated collagen solution enters the plate evaporator 8 and exchanges heat with heating steam, vaporizing and boiling. The gas-liquid mixture enters the separator 4 for cyclone separation. Secondary steam is discharged from the top of the separator 4. As water evaporates, the collagen solution is concentrated. After concentration, the collagen solution enters the circulation pump 13. Part of it is discharged from the system, and the other part is returned to the plate evaporator 8 for further evaporation and concentration. Each group of the evaporator consists of two plates of different shapes. The steam side is sealed using a fully welded process, while the material side is sealed using EPDM. The material enters from the middle of the lower end of the plate, the steam-water mixture exits from the large irregular opening at the upper end of the plate, the steam enters from the small irregular opening at the upper end of the plate, and the condensate exits from the left and right openings at the lower end. Low-resistance corrugations are used to ensure uniform medium distribution, low resistance, and high efficiency. The discharge unit system is equipped with a density meter installed in the discharge pipeline to monitor the density of the concentrate. The density is directly proportional to the concentration of the concentrate; the concentration can be determined by the density, and the concentration of the concentrate is controlled by the discharge regulating valve. The secondary steam in separator 4 enters the secondary gas-liquid separator 5 for further separation of steam droplets. It then enters the steam compressor 14, where an electrically driven impeller compresses the secondary steam, increasing its temperature and pressure. The saturated temperature of the compressed steam is higher than that of the collagen solution, allowing it to be used as a heat source in the plate evaporator 8. In the plate evaporator 8, the secondary steam exchanges heat with the collagen solution, releasing latent heat, and then condenses into condensate, which flows into the condensate tank 3. The vacuum unit employs negative pressure evaporation. To ensure the vacuum level of the evaporation system, a vacuum control unit is configured. The air volume control depends on the amount of non-condensable gas extracted. The condensate tank 3 contains a trace amount of non-condensable gas. The non-condensable gas and a small amount of steam are discharged from the top of the condensate tank 3 and enter the non-condensable gas plate condenser 7. After exchanging heat with the circulating water and cooling down, the condensate flows into the non-condensable gas condensate storage tank 2. The non-condensable gas in the non-condensable gas condensate storage tank 2 is discharged from the top and is sucked out of the system by the vacuum pump 11. After the steam releases its latent heat, it condenses into condensate and is collected in the condensate tank 3 and the non-condensable gas condensate storage tank 2. It is then transported to the condensate plate preheater 6 by the condensate pump 12 and the non-condensable gas condensate pump 10 to exchange heat with the collagen solution feed liquid and cool down before leaving the system.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
