Description

Technical Field

[0001] The utility model relates to the field of birch sap production devices, in particular to a birch sap low-temperature concentration device. Background Art

[0002] Birch sap is the sap that flows out of the birch family, containing carbohydrates, amino acids, trace elements, cytokinins, and auxins that are easily absorbed by the human body. When birch sap is purified and prepared, it needs to be processed by low-temperature concentration. The working principle of low-temperature concentration is: first, the birch sap liquid is heated by a heating device, so that the birch sap liquid evaporates and becomes gas, and then the gas is extracted into a sealed container, and the birch sap steam is cooled by a heat exchange device in the sealed container, so that the steam is cooled and forms a paste, thereby realizing the low-temperature concentration of birch sap.

[0003] In the prior art, when birch sap is subjected to low-temperature concentration treatment, due to the contact between steam and the contact area of ​​the heat exchanger, a part of the condensed birch sap paste will adhere to the surface of the heat exchanger. The heat exchanger generally removes heat by circulating coolant. If the birch sap paste adheres to the surface of the heat exchanger for a long time, the temperature in the container will decrease slowly, and the subsequent steam cannot be condensed quickly, and the steam cools slowly, which reduces the efficiency of the low-temperature concentration treatment of birch sap.

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0019] like Figures 1 to 3 The birch juice low-temperature concentration device shown in the figure comprises a processing box 1 and a push plate 2. The processing box 1 is threadedly connected to a box cover 12. A heat-conducting ring 3 is connected to the inner side of the processing box 1. The heat-conducting ring 3 is provided with a flow channel 15. The heat-conducting ring 3 is connected to a liquid inlet pipe 4 and a liquid discharge pipe 16. The liquid inlet pipe 4 and the liquid discharge pipe 16 are connected to a cooling liquid source and a recovery device respectively. The inner wall of the heat-conducting ring 3 is flush with the inner wall of the processing box 1. The push plate 2 is slidably connected to the processing box 1. The push plate 2 acts as a piston plate. The push plate 2 is connected to a moving square rod 17. The cover 12 is connected to a positioning rod 19, the positioning rod 19 is provided with a limiting square groove 20, the movable square rod 17 is slidably connected to the limiting square groove 20, the movable square rod 17 can only move up and down along the limiting square groove 20, the box cover 12 is rotatably connected to a threaded rod 18, the box cover 12 is connected to a servo motor 21, the output shaft of the servo motor 21 is connected to the threaded rod 18, the threaded rod 18 is rotatably connected to the positioning rod 19, and the movable square rod 17 is threadedly connected to the threaded rod 18; the processing box 1 is connected to an air intake pipe 5, and the air intake pipe 5 is located below the heat conductive ring 3.

[0020] The processing box 1 is connected to a supporting foot 6 , the processing box 1 is connected to a cylinder 7 , the cylinder 7 is connected to a mounting plate 9 , and the mounting plate 9 is connected to a universal wheel 8 .

[0021] The processing box 1 is connected to a vent pipe 13, the vent pipe 13 is connected to a solenoid valve 14, and the box cover 12 can also be connected to the vent pipe 13 to facilitate the movement of the push plate 2. The bottom of the processing box 1 is connected to a discharge pipe 11, and the discharge pipe 11 is connected to a control switch 10; the bottom of the processing box 1 is conical.

[0022] The servo motor 21 drives the threaded rod 18 to rotate, and the limiting square groove 20 and the positioning rod 19 play a role in rotation limiting the movable square rod 17. Therefore, as the threaded rod 18 rotates, the movable square rod 17 moves upward or downward along the threaded rod 18, thereby driving the push plate 2 to move upward or downward. Since the push plate 2 acts as a piston plate, the birch sap steam will not pass through the push plate 2 to reach the top of the push plate 2.

[0023] The specific implementation process is as follows:

[0024] When using Figure 1The installation device shown in the figure is grounded when in use, and the coolant is sent from the liquid inlet pipe 4 into the flow channel 15 through an external coolant source and a pump. The coolant flows along the flow channel to take away the heat on the heat-conducting ring 3, and then is discharged from the liquid discharge pipe 16, thereby completing the cooling of the inside of the processing box 1. Birch sap steam is input through the air inlet pipe 5, and the birch sap steam is used to cool the inside of the processing box 1 to form a paste. A part of the paste will adhere to the inner wall of the heat-conducting ring 3. After a period of time, the servo motor 21 can be started to drive the push plate 2 to move downward, thereby scraping off the paste attached to the heat-conducting ring 3, so that the paste gathers at the bottom of the processing box 1, and then the push plate 2 can be restored to its original state. While continuing the cooling treatment, when the push plate 2 moves, the solenoid valve 14 of the ventilation pipe 13 on the processing box 1 or the ventilation pipe 13 on the box cover 12 can be opened according to actual conditions to facilitate the stable movement of the push plate 2; after cooling, turn on the control switch 10, control the servo motor 21 to drive the push plate 2 to move downward, so that the paste in the processing box 1 can be quickly discharged from the processing box 1, and the push plate 2 can scrape off all the paste attached to the side wall of the processing box 1; subsequently, the box cover 12 can be opened to clean the processing box 1, and when the device needs to be moved, it is only necessary to control the cylinder 7 to drive the mounting plate 9 and the universal wheel 8 to move downward, and then the universal wheel 8 can be grounded to quickly push the device.

[0025] The technical solution performs heat exchange through the heat-conducting ring 3, inputs coolant through the flow channel 15 to cool the inside of the processing box 1, and then cools the steam. A push plate 2 is provided, and the push plate 2 can be driven downward by the servo motor 21 to drive the threaded rod 18 to rotate, so that the paste attached to the side wall of the heat-conducting ring 3 can be scraped off, thereby improving the heat exchange efficiency, making it easier for the heat-conducting ring 3 to take away the heat in the processing box 1, and facilitating the subsequent cooling and condensation of the steam, thereby improving the processing efficiency; the birch sap steam is prevented from assisting the threaded rod 18 by means of the limiting square rod, the positioning rod 19 and the push plate 2, thereby improving the stability of the device. At the same time, the paste attached to the inner wall of the processing box 1 can be scraped off by the push plate 2, so that the paste can be quickly discharged from the processing box 1, thereby improving the convenience and practicality of use. Support feet 6 and universal wheels 8 are provided, so that the device can be placed stably for use and convenient for rapid movement, and the universal wheels 8 do not need to be grounded for a long time, thereby improving the stability of use and the service life of the universal wheels 8; the air pressure inside the processing box 1 can be adjusted through the ventilation pipe 13, which improves the safety of use and facilitates the movement of the push plate 2; the conical setting of the bottom of the processing box 1 facilitates the rapid discharge of the paste.

[0026] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here.
