A plant pulp vacuum concentration and sterilization equipment

Abstract

This utility model relates to the field of vacuum concentrator technology, specifically a plant pulp vacuum concentration and sterilization device, including a storage tank with a connecting interface at the top. When the concentrated liquid enters the sterilization chamber through the second infusion pipe, the heat-conducting layer and the heat-conducting block adhere to each other. Thus, when the heater is running, the adhesion between the heat-conducting layer and the heat-conducting block can stably provide a continuous and constant temperature to the inside of the sterilization chamber to efficiently concentrate the liquid. Then, the concentrated liquid enters the storage tank through the connecting interface. Compared with traditional vacuum concentration and extraction equipment, this reduces the sterilization steps, thereby improving efficiency and saving time.

Description

Technical Field

[0001] This utility model relates to the field of vacuum concentrator technology, specifically to a plant pulp vacuum concentration and sterilization device. Background Technology

[0002] Vacuum concentration involves the induction of secondary steam and the suction of a high vacuum in the separator, causing the concentrated material and secondary steam to enter the separator tangentially at a relatively high speed. Vacuum technology preserves the nutrients and aroma of the raw materials.

[0003] Publication number CN217187916U discloses a vacuum concentrator that achieves a sealing effect by directly connecting the motor's output shaft to the inside of the concentrator tank through the cooperation of a motor, water cover, inlet, and outlet. This solves the leakage problem during operation, reduces the workload of the vacuum port, allows the concentrator tank to achieve a stable vacuum level, and eliminates the need for frequent replacement of easily damaged mechanical seal parts, thus reducing operating costs. However, this device cannot simultaneously sterilize the concentrate during vacuum concentration. After extracting the concentrate into the container, it still needs to be moved to a sterilization machine for sterilization, which is time-consuming, labor-intensive, and has relatively low production efficiency. Therefore, we propose a plant pulp vacuum concentration and sterilization device. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a plant pulp vacuum concentration and sterilization device.

[0005] The technical solution adopted by this utility model to solve its technical problem is a plant pulp vacuum concentration and sterilization device, including a storage tank. The top of the storage tank is connected to a transfer interface. The top of the transfer interface is fitted with a sterilization chamber through a flange. The bottom outer wall of the sterilization chamber is provided with a heat-conducting layer. The sterilization chamber is connected to a heat-conducting block through the heat-conducting layer. One end of the heat-conducting block is fitted with a heater for controlling the heating temperature. The top of the sterilization chamber is fitted with a top liquid inlet interface. The top of the top liquid inlet interface is connected to a second liquid delivery pipe.

[0006] The second infusion tube is connected to the top of the evaporator at one end away from the top inlet port. An evaporation exhaust pipe is connected to the side wall of the evaporator. The end of the evaporation exhaust pipe away from the evaporator is connected to the top of the heating tank. A condensate tank is integrally formed on the inner wall of the side of the evaporation exhaust pipe facing the heating tank. A temporary storage tube is connected to one side of the condensate tank. The bottom end of the temporary storage tube is connected to the top of the heating tank.

[0007] By adopting the above technical solution, when the concentrate enters the sterilization chamber through the second infusion tube, the heat-conducting layer and the heat-conducting block are bonded together. Thus, when the heater is running, the bond between the heat-conducting layer and the heat-conducting block can stably provide a continuous and constant temperature to the inside of the sterilization chamber to efficiently concentrate the liquid. Then, the concentrate enters the storage tank through the adapter interface. Compared with traditional vacuum concentration and extraction equipment, this reduces the sterilization operation steps, relatively improves efficiency, and saves time.

[0008] After the raw materials are placed inside the heating tank, water is introduced through the inlet pipe and heating begins. The heated mixture vapor is drawn out by the vacuum pump and enters the interior of the evaporator through the evaporation exhaust pipe for evaporation. After evaporation, the concentrated liquid enters the second inlet pipe at the top and enters the sterilization chamber for sterilization. During the transport of the mixture, the liquid that condenses and accumulates on the inner wall and slides down is collected through the condensate tank at the end of the evaporation exhaust pipe facing the heating tank. The condensate is temporarily stored by closing the valve at the bottom of the temporary storage pipe that runs through its side wall, so as to avoid affecting the heating efficiency of the heating tank during the initial heating. After heating for a certain period of time, the valve is opened to form a return pipeline, allowing the liquid in the temporary storage pipe to enter the interior of the heating tank.

[0009] Specifically, the heat-conducting block is fixed to the outer wall of the heat-conducting layer by bolts, which lock the two ends of the hinge connection.

[0010] By adopting the above technical solution, the detachable heating component structure facilitates the removal of the heat-conducting block for inspection and maintenance.

[0011] Specifically, the top cover of the heating tank is connected to the tank body in a sealed manner by bolts and sealing gaskets.

[0012] By adopting the above technical solution, the heating tube is locked with bolts and a sealing gasket is used to prevent gaps from causing a decrease in the internal pressure of the tank.

[0013] Specifically, the middle section of the adapter, the second infusion pipe, and the evaporation exhaust pipe is equipped with a switch valve for controlling the on / off state of the pipeline.

[0014] By adopting the above technical solution, the on / off switches installed in each pipeline are used to control the flow between the pipelines of each tank, thereby initiating the vacuum concentration process.

[0015] Specifically, the bottom side wall of the storage tank is equipped with a discharge port for unloading.

[0016] By adopting the above technical solution, the concentrated and sterilized pulp concentrate can be taken out through the discharge port, and can be opened as a pressure relief port under special circumstances.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When the concentrate enters the sterilization chamber through the second infusion tube, the heat-conducting layer and the heat-conducting block are in contact. Thus, when the heater is running, the heat-conducting layer and the heat-conducting block can stably provide a continuous and constant temperature to the inside of the sterilization chamber to efficiently heat the concentrate. Then, it enters the storage tank through the adapter interface. Compared with traditional vacuum concentration and extraction equipment, the sterilization operation steps are reduced, which improves efficiency and saves time.

[0019] 2. After the raw materials are placed inside the heating tank, water is introduced through the water inlet pipe and heating begins. The heated mixture vapor is drawn out by the vacuum pump and enters the interior of the evaporation tank through the evaporation exhaust pipe for evaporation. After evaporation, the concentrated liquid enters the second liquid delivery pipe at the top and enters the sterilization chamber for sterilization. During the transportation of the mixture, the liquid that condenses and accumulates on the inner wall and slides down is collected through the condensate tank at the end of the evaporation exhaust pipe facing the heating tank. The condensate liquid is temporarily stored by closing the valve body at the bottom of the temporary storage pipe that runs through its side wall, so as to avoid affecting the heating efficiency of the heating tank during the initial heating. After heating for a certain period of time, the valve body is opened to form a return pipeline so that the liquid in the temporary storage pipe enters the interior of the heating tank.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figure 1-3This utility model provides a technical solution: including a storage tank 1, with a connecting interface 2 penetrating the top of the storage tank 1, a sterilization chamber 3 being fitted to the top of the connecting interface 2 via a flange, a heat-conducting layer 4 being provided on the bottom outer wall of the sterilization chamber 3, and the sterilization chamber 3 being connected to a heat-conducting block 5 via the heat-conducting layer 4, a heater 6 for controlling the heating temperature being fitted to one end of the heat-conducting block 5, a top liquid inlet 7 being fitted to the top of the sterilization chamber 3, and a second infusion pipe 8 being penetratingly connected to the top of the top liquid inlet 7;

[0027] The second infusion tube 8 is connected to the top of the evaporator 9 at one end away from the top inlet port 7. An evaporation exhaust pipe 10 is connected to the side wall of the evaporator 9. The end of the evaporation exhaust pipe 10 away from the evaporator 9 is connected to the top of the heating tank 11. A condensate tank 12 is integrally formed on the inner wall of the side of the evaporation exhaust pipe 10 facing the heating tank 11. A temporary storage pipe 13 is connected to one side of the condensate tank 12. The bottom end of the temporary storage pipe 13 is connected to the top of the heating tank 11.

[0028] When the concentrate enters the sterilization chamber 3 through the second infusion pipe 8, the heat-conducting layer 4 and the heat-conducting block 5 are in contact. Thus, when the heater 6 is running, the heat-conducting layer 4 and the heat-conducting block 5 can stably provide a continuous and constant temperature to the inside of the sterilization chamber 3 to efficiently concentrate the liquid. Then, it enters the storage tank 1 through the adapter interface 2. Compared with traditional vacuum concentration and extraction equipment, the sterilization operation steps are reduced, which improves efficiency and saves time.

[0029] After the raw materials are placed inside the heating tank 11, water is introduced through the water inlet pipe and heating begins. The heated mixture vapor is extracted by the vacuum pump and enters the evaporation tank 9 through the evaporation exhaust pipe 10 for evaporation. After evaporation, the concentrated liquid enters the second liquid delivery pipe 8 at the top and enters the sterilization chamber 3 for sterilization. During the transportation of the mixture, the liquid that condenses and accumulates on the inner wall and slides down is collected through the condensate tank 12 at the end of the evaporation exhaust pipe 10 facing the heating tank 11. The condensate liquid is temporarily stored by closing the valve body at the bottom of the temporary storage pipe 13 that is connected through its side wall, so as to avoid affecting the heating efficiency of the heating tank 11 during the initial heating. After heating for a certain period of time, the valve body is opened to form a return pipeline so that the liquid in the temporary storage pipe 13 enters the interior of the heating tank 11.

[0030] As shown in the figure, the heat-conducting block 5 is fixed to the outer wall of the heat-conducting layer 4 by bolts, with the two ends of the hinge connection locked together.

[0031] During use, the detachable heating component structure makes it easy to remove the heat-conducting block 5 for inspection and maintenance.

[0032] As shown in the figure, the top cover of the heating tank 11 is connected to the tank body in a sealed manner by bolts and sealing gaskets.

[0033] When in use, the heating tube is locked shut with bolts and sealed with gaskets to prevent gaps that could cause a drop in internal pressure.

[0034] As shown in the figure, the middle sections of the adapter interface 2, the second infusion pipe 8, and the evaporation exhaust pipe 10 are all equipped with switch valves for controlling the on / off state of the pipeline.

[0035] During use, the on / off valves installed in each pipeline control the flow between the pipelines of each tank, thereby initiating the vacuum concentration process.

[0036] As shown in the figure, the bottom side wall of the liquid storage tank 1 is equipped with a discharge port for unloading.

[0037] When in use, the concentrated and sterilized pulp concentrate is taken out through the discharge port, and can be opened as a pressure relief port in special circumstances.

[0038] The working principle and usage process of this utility model are as follows: After the raw materials are placed inside the heating tank 11, the heating pipe is locked with bolts and sealed with a gasket to prevent gaps that could cause a decrease in internal pressure. Water is introduced through the water inlet pipe and heating begins. The vapor of the heated mixture is extracted by a vacuum pump and enters the evaporation tank 9 through the evaporation exhaust pipe 10 for evaporation. After evaporation, the concentrated liquid enters the second inlet pipe 8 at the top and then enters the sterilization chamber 3 for sterilization. During the transport of the mixture, the liquid that condenses and drips from the inner wall is collected by the condensate tank 12 at the end of the evaporation exhaust pipe 10 facing the heating tank 11. The condensate is temporarily stored by closing the valve at the bottom of the temporary storage pipe 13, which is connected to the side wall, to avoid affecting the heating efficiency of the heating tank 11 during the initial heating process. After heating for a certain period of time, the valve is opened to form a return flow. The flow pipeline allows the liquid in the temporary storage pipe 13 to enter the interior of the heating tank 11. The switching valves installed in each pipeline control the opening and closing of the pipelines between the tanks, thus initiating the vacuum concentration process. When the concentrated liquid enters the interior of the sterilization chamber 3 through the second infusion pipe 8, the heat-conducting layer 4 and the heat-conducting block 5 are in contact. Thus, when the heater 6 is running, the contact between the heat-conducting layer 4 and the heat-conducting block 5 can stably provide a continuous and constant temperature to the interior of the sterilization chamber 3 to efficiently concentrate the liquid. Subsequently, it enters the interior of the storage tank 1 through the adapter interface 2. Compared with traditional vacuum concentration and extraction equipment, the sterilization operation steps are reduced, which relatively improves efficiency and saves time. The detachable heating component structure makes it easy to remove the heat-conducting block 5 for inspection and maintenance. The concentrated and sterilized raw pulp concentrate is taken out through the discharge port, which can also be opened as a pressure relief port in special circumstances.
