Description

Technical Field

[0001] This utility model relates to the field of bioenzyme concentration technology, and in particular to an evaporation and concentration device for bioenzyme preparations. Background Technology

[0002] Bioenzyme preparations refer to biocatalysts with specific catalytic functions produced through bioengineering technologies (such as microbial fermentation, genetic engineering, protein engineering, etc.).

[0003] In the production of biological enzyme preparations, the enzyme concentration in fermentation broth or enzyme extract is often low. In order to meet the requirements of subsequent processes (such as precipitation treatment, direct drying, or selling as liquid enzyme preparations), the dilute enzyme solution must be concentrated to a certain concentration. During the evaporation and concentration process of biological enzyme preparations, the steam usually carries solvent (such as ethanol) or trace amounts of enzyme solution, which not only wastes solvent but may also pollute the environment. At the same time, the loss of trace amounts of enzyme solution will affect the product yield.

[0004] Therefore, it is necessary to provide an evaporation and concentration apparatus for biological enzyme preparations to solve the above-mentioned technical problems. Utility Model Content

The top end of the stirring rod is connected to the output shaft of the stirring motor through a coupling, and the stirring rod is provided with multiple stirring blades.

[0010] Preferably, one end of the stirring blade is provided with a scraper, and the scraper is in contact with the inner wall of the box.

[0013] Compared with related technologies, the evaporation and concentration device for biological enzyme preparations provided by this utility model has the following beneficial effects:

[0014] This invention provides an evaporation and concentration apparatus for biological enzyme preparations:

[0015] 1. The filter screen can intercept impurities and particulate matter during the feeding stage, reducing the impact of impurities on the evaporation and concentration process and avoiding potential damage to the quality of biological enzyme preparations. This helps improve the purity and quality of the final concentrated product. The vacuum environment provided by the vacuum pump lowers the boiling point of the solution, and the steam recovery mechanism can effectively recover solvent and trace amounts of enzyme solution from the steam, avoiding solvent waste and reducing production costs. The vacuum environment created by the vacuum pump lowers the boiling point of the solution in the chamber, allowing solvents (such as ethanol) to evaporate quickly at lower temperatures, greatly increasing the speed of evaporation and concentration, shortening the entire production process time, and improving production efficiency. For heat-sensitive biological enzyme solutions, evaporation and concentration in a vacuum environment avoids the destruction of enzyme activity by high temperatures, maximizing the preservation of the enzyme's biological activity and function, and ensuring the quality of the final product.

[0016] 2. By bringing the high-temperature steam into contact with the inner wall of the low-temperature cooling chamber, the solvent and trace enzyme solution in the steam can be effectively condensed and recovered, avoiding the waste of solvent and reducing production costs. At the same time, the recovered enzyme solution can also be reused, improving the utilization rate of resources. The stirring action of the stirring blades keeps the biological enzyme preparation in the chamber flowing continuously, avoiding local overheating or overcooling, ensuring that the biological enzyme preparation is heated evenly during the evaporation and concentration process, and improving the efficiency and quality of evaporation and concentration.

[0017] 3. The scraper adheres to the inner wall of the chamber, promptly scraping off materials adhering to the inner wall during stirring, preventing material accumulation and ensuring the cleanliness of the inner wall. This avoids uneven heating and localized overheating caused by material sticking to the wall. The temperature sensor continuously monitors the temperature changes of the biological enzyme preparation inside the chamber, allowing operators to understand temperature fluctuations and adjust the temperature as needed. This prevents excessively high or low temperatures from affecting the activity of the biological enzyme preparation, ensuring stable product quality. The combination of slots, blocks, and magnetic blocks makes the installation and removal of the filter screen simple and easy. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1-3 ,in, Figure 1 A front view schematic diagram of a preferred embodiment of the evaporation and concentration apparatus for biological enzyme preparations provided by this utility model; Figure 2 A schematic front cross-sectional view of a preferred embodiment of the evaporation and concentration apparatus for biological enzyme preparations provided by this utility model; Figure 3 for Figure 2 The diagram shows an enlarged view of part A.

[0024] The evaporation and concentration apparatus for biological enzyme preparations includes: a housing 1, with a feed pipe 2 fixedly connected to the top of the housing 1, a filter screen 3 detachably installed inside the feed pipe 2, and a discharge pipe 4 fixedly connected to the bottom of the housing 1; a heating plate 5 disposed on the inner wall of the housing 1; a vacuum mechanism disposed on the housing 1 to provide a vacuum environment for the evaporation and concentration of biological enzyme preparations; and a steam recovery mechanism disposed on the housing 1 to recover solvent and enzyme solution from the steam. The filter screen 3 intercepts impurities and particulate matter during the feeding stage, reducing the impact of impurities on the evaporation and concentration process and preventing potential damage to the quality of the biological enzyme preparations. This helps improve the purity and quality of the final concentrated product. The vacuum environment provided by the vacuum mechanism lowers the boiling point of the solution, and the steam recovery mechanism effectively recovers solvent and trace amounts of enzyme solution from the steam, avoiding solvent waste and reducing production costs.

[0025] The vacuum pump mechanism includes a vacuum pump 6 and a suction pipe 7. The vacuum pump 6 is fixedly installed on one side of the housing 1, and the suction pipe 7 is fixedly connected to the vacuum pump 6. The air inlet of the suction pipe 7 is connected to the top of the housing 1. The vacuum environment created by the vacuum pump 6 lowers the boiling point of the solution in the housing 1, allowing the solvent (such as ethanol) to evaporate quickly at a lower temperature. This greatly improves the speed of evaporation and concentration, shortens the time of the entire production process, and improves production efficiency. For heat-sensitive biological enzyme solutions, evaporation and concentration in a vacuum environment avoids the destruction of enzyme activity by high temperature, preserves the biological activity and function of the enzyme solution to the greatest extent, and ensures the quality of the final product.

[0026] The steam recovery mechanism includes an exhaust pipe 8, a one-way valve 9, a condenser 10, a cooling chamber 11, an inlet pipe 12, and a drain pipe 13. The exhaust pipe 8 is fixedly connected to the top of the housing 1, and the one-way valve 9 is located on the exhaust pipe 8. The condenser 10 is fixedly installed on one side of the housing 1 and is connected to the exhaust pipe 8. The cooling chamber 11 is located inside the condenser 10 and is used to store coolant. The inlet pipe 12 and the drain pipe 13 are both fixedly connected to the condenser 10. By contacting the high-temperature steam with the low-temperature inner wall of the cooling chamber 11, the solvent and trace amounts of enzyme solution in the steam can be effectively condensed and recovered, avoiding solvent waste and reducing production costs. At the same time, the recovered enzyme solution can also be reused, improving resource utilization.

[0027] A stirring motor 14 is fixedly installed on the top of the housing 1, and a stirring rod 15 is rotatably installed on the housing 1. The top end of the stirring rod 15 is connected to the output shaft of the stirring motor 14 through a coupling. The stirring rod 15 is provided with multiple stirring blades 16. The stirring action of the stirring blades 16 makes the biological enzyme preparation in the housing 1 flow continuously, avoiding local overheating or overcooling, ensuring that the biological enzyme preparation is heated evenly during the evaporation and concentration process, and improving the efficiency and quality of evaporation and concentration.

[0028] One end of the stirring blade 16 is provided with a scraper 17, which is in contact with the inner wall of the box 1. By having the scraper 17 in contact with the inner wall of the box 1, the material adhering to the inner wall can be scraped off in time during the stirring process, preventing the material from accumulating on the inner wall of the box 1, ensuring the cleanliness of the inner wall of the box 1, and avoiding uneven heating and local overheating caused by material sticking to the wall.

[0029] A temperature sensor 18 is fixedly installed on the box 1. The sensing end of the temperature sensor 18 extends into the box 1. The sensing end of the temperature sensor 18 continuously senses the temperature change of the biological enzyme preparation inside the box 1, which can monitor the temperature of the biological enzyme preparation inside the box 1 in real time. This allows the operator to understand the temperature change in a timely manner and adjust the temperature according to actual needs, avoiding the impact of excessively high or low temperatures on the activity of the biological enzyme preparation and ensuring stable product quality.

[0030] A fixing plate 19 is fixedly installed on the inner wall of the feed pipe 2. A slot 20 is provided on the fixing plate 19. A block 21 is provided at the bottom of the filter screen 3. A magnetic block 22 is provided on both the slot 20 and the block 21. The two magnetic blocks 22 attract each other. Through the cooperation of the slot 20, the block 21 and the magnetic block 22, the installation and disassembly of the filter screen 3 is simple and easy.

[0031] It is worth noting that the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0032] The working principle of the evaporation and concentration device for biological enzyme preparations provided by this utility model is as follows:

[0033] In use, the bio-enzyme preparation to be evaporated and concentrated is injected into the chamber 1 through the feed pipe 2. During the feeding process, the filter screen 3 in the feed pipe 2 will perform preliminary filtration of the bio-enzyme preparation, intercepting any impurities or particulate matter that may be present, and preventing them from entering the chamber 1 and affecting the subsequent evaporation and concentration process.

[0034] Before evaporation and concentration, vacuum pump 6 is started. Vacuum pump 6 starts working and generates suction force. Since the suction pipe 7 is fixedly connected to vacuum pump 6 and the air inlet end of suction pipe 7 is connected to the top of box 1, the suction force generated by vacuum pump 6 is transmitted to box 1 through suction pipe 7. Under the action of suction force, the air in box 1 is gradually extracted, thereby creating a vacuum environment in box 1.

[0035] During evaporation and concentration, the heating plate 5 is activated. The heating plate 5 is located on the inner wall of the chamber 1 and begins to heat the biological enzyme preparation in the chamber 1, causing the solvent (such as ethanol) to evaporate and form steam. In a vacuum environment, the boiling point of the solution is lowered, which helps to accelerate the evaporation of the solvent, improve the evaporation and concentration efficiency, and reduce the risk of heat-sensitive enzyme solution being deactivated due to high temperature. As evaporation and concentration proceed, steam is generated in the chamber 1 and discharged through the exhaust pipe 8 fixedly connected to the top of the chamber 1, and enters the condenser 10. The high-temperature steam comes into contact with the inner wall of the low-temperature cooling chamber 11. As the steam temperature decreases, the steam gradually condenses into liquid (containing solvent and trace amounts of enzyme solution). The condensed liquid is collected at the bottom of the condenser 10. When it is necessary to process the condensed liquid, the liquid is discharged from the condenser 10 for subsequent recycling or further processing.

[0036] During the evaporation and compression process, the stirring motor 14 is started. The output shaft of the stirring motor 14 is connected to the top of the stirring rod 15 through a coupling. When the stirring motor 14 starts, its output shaft begins to rotate, driving the stirring rod 15 to rotate on the box 1. The stirring rod 15 is equipped with multiple stirring blades 16. As the stirring rod 15 rotates, the stirring blades 16 stir the biological enzyme preparation in the box 1. The scraper 17 continuously scrapes along the inner wall of the box 1, stirring the biological enzyme preparation to ensure that it is heated evenly, while cleaning the inner wall of the box 1. Throughout the evaporation and concentration process, the stirring motor 14 continues to run, and the stirring blades 16 continuously stir to ensure that the biological enzyme preparation is heated evenly until the biological enzyme preparation reaches the required concentration level. Finally, it is discharged through the discharge pipe 4, completing the entire evaporation and concentration process.

[0037] When the filter screen 3 needs to be cleaned or replaced, the operator only needs to apply a certain external force to overcome the attraction between the magnetic blocks 22 and pull the card block 21 at the bottom of the filter screen 3 out of the card slot 20 of the fixing plate 19, so that the filter screen 3 can be removed from the feed pipe 2.

[0038] Compared with related technologies, the evaporation and concentration device for biological enzyme preparations provided by this utility model has the following beneficial effects:

[0039] This invention provides an evaporation and concentration device for biological enzyme preparations. The filter 3 intercepts impurities and particulate matter during the feeding stage, reducing the impact of impurities on the evaporation and concentration process and preventing potential damage to the quality of the biological enzyme preparations. This helps improve the purity and quality of the final concentrated product. The vacuum environment provided by the vacuum pump lowers the boiling point of the solution, and the steam recovery mechanism effectively recovers solvent and trace amounts of enzyme solution from the steam, avoiding solvent waste and reducing production costs. The vacuum environment created by the vacuum pump 6 lowers the boiling point of the solution inside the chamber 1, allowing solvents (such as ethanol) to evaporate rapidly at lower temperatures, greatly increasing the evaporation and concentration speed, shortening the overall production process time, and improving production efficiency. For heat-sensitive biological enzyme solutions, evaporation and concentration under vacuum avoids the destruction of enzyme activity by high temperatures, maximizing the preservation of the enzyme's biological activity and function, and ensuring the quality of the final product. By contacting the higher-temperature steam with the lower-temperature inner wall of the cooling chamber 11, the solvent and trace amounts of enzyme solution in the steam can be effectively condensed and recovered. This process avoids solvent waste, reduces production costs, and allows for the reuse of the recovered enzyme solution, improving resource utilization. The stirring action of the stirring blades 16 ensures continuous flow of the bio-enzyme preparation within the chamber 1, preventing localized overheating or undercooling and ensuring uniform heating during evaporation and concentration, thus improving efficiency and quality. The scraper 17, which adheres to the inner wall of the chamber 1, effectively removes material adhering to the inner wall during stirring, preventing material accumulation and ensuring the cleanliness of the chamber's inner wall. To prevent uneven heating and localized overheating caused by material sticking to the walls, the temperature sensor 18 continuously senses the temperature changes of the bio-enzyme preparation inside the chamber 1. This allows for real-time monitoring of the temperature of the bio-enzyme preparation inside the chamber 1, enabling operators to understand temperature changes promptly and adjust the temperature according to actual needs. This prevents excessively high or low temperatures from affecting the activity of the bio-enzyme preparation, ensuring stable product quality. The cooperation of the slot 20, the card block 21, and the magnetic block 22 makes the installation and removal of the filter screen 3 simple and easy.
