Description

Technical Field

[0001] The utility model relates to the field of freeze-drying machines, and particularly relates to a freeze-drying machine convenient for cleaning. Background Art

[0002] A freeze-drying machine is a device that uses physical principles to separate and remove moisture from materials. By lowering the temperature of the materials, the moisture in them directly sublimes from a solid state to a gaseous state, thereby achieving the purpose of drying. This process mainly includes three steps: precooling, freezing, and dehydration. Precooling is the process of lowering the temperature of the materials, freezing is cooling the materials below their freezing point so that the moisture directly changes from a solid state to a gaseous state, and dehydration is the process of the moisture evaporating from the materials and being pumped out by a vacuum pump.

[0003] After retrieval, a freeze-drying machine with the publication number CN219810160U specifically discloses a freeze-drying machine: including a freeze-drying machine body, the projection of the freeze-drying machine body in the top view direction presents a rectangle, and adjustable support walking mechanisms are provided at the four bottom corners of the freeze-drying machine body. The structure is novel and uniquely designed. The universal walking wheels are separated from the support surface, and the annular support pad contacts the support surface, enabling the freeze-drying machine body to be stably placed, facilitating the adjustment of the overall placement stability of the device, adapting to uneven ground. When the universal walking wheels contact the support surface and the annular support pad is separated from the support surface, the whole device is convenient to move and switch states, has high practicability, is worthy of promotion, and has high commercial value.

[0004] During the use of existing freeze-drying machines, since the internal cleanliness of the freeze-drying machine directly affects the quality of freeze-dried products and the accuracy of experimental results, if not cleaned regularly, residual impurities, microorganisms, or residues from previous experiments may contaminate subsequent samples, resulting in cross-contamination and thus affecting product quality. Currently, the cleaning of existing freeze-drying machines is to disassemble the sealing cylinder and the material tray for manual cleaning, and the freeze-drying machine in the above comparative case also lacks a method for conveniently cleaning the sealing cylinder and the material tray. In the long term, this not only increases the labor intensity of workers but also prolongs the cleaning time.

[0005] Therefore, it is very necessary to invent a freeze-drying machine convenient for cleaning to solve the above problems. Content of the Utility Model

The entire cleaning process is realized through an outer sealing cylinder, an inner cleaning ring, a cleaning nozzle, an outer liquid inlet pipe, a cleaning water tank, a pressurizing water pump, a water pumping pipe, and a water supply pipe, reducing the labor intensity of workers. The operator only needs to dry the outer sealing cylinder, the material bottom tray, and the upper material tray after cleaning. Such a combination enables the freeze dryer to have the ability to be conveniently cleaned and shortens the overall cleaning time, so as to solve the problem that in the prior art, during the use of a freeze dryer, since the internal cleanliness of the freeze dryer directly affects the quality of freeze-dried products and the accuracy of experimental results, if not cleaned regularly, residual impurities, microorganisms, or residues from previous experiments may contaminate subsequent samples, resulting in cross-contamination and thus affecting product quality. The existing freeze dryers are all cleaned by manually disassembling the sealing cylinder and the material tray, and the freeze dryer in the above comparative case also lacks a method for conveniently cleaning the sealing cylinder and the material tray.

Detailed implementation manners

[0027] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0028] The present utility model provides a freeze-drying machine as shown in Figures 1-5 Figure, which includes a freeze-drying machine body 1, the main body for freeze-drying materials;

[0029] A display controller 2, which is arranged outside the freeze-drying machine body 1 and is used to adjust the freeze-drying machine body 1. And an upper table board 3 is fixedly installed above the freeze-drying machine body 1. An embedded groove 4 is opened inside the upper table board 3. An embedded block 6 is movably connected inside the embedded groove 4. One end of the embedded block 6 is fixedly installed with an outer sealing cylinder 7;

[0030] A liquid outlet pipe 15, which is arranged outside the outer sealing cylinder 7 and is used to discharge the liquid after cleaning. And an inner cleaning ring 16 is fixedly installed inside the outer sealing cylinder 7. A cleaning spray head 17 is arranged inside the inner cleaning ring 16. An outer liquid inlet pipe 18 is fixedly installed outside the inner cleaning ring 16;

[0031] The cleaning water tank 19 is arranged outside the freeze-drying machine body 1 and is used to provide cleaning liquid for the outer sealing cylinder 7. A pressurized water pump 20 is fixedly installed above the cleaning water tank 19. One end of the pressurized water pump 20 is fixedly installed with a water suction pipe 21, and the other end of the pressurized water pump 20 is fixedly installed with a water supply pipe 22. The water supply pipe 22 can be connected to the outer liquid inlet pipe 18, so that the pressurized water pump 20 can extract the liquid in the cleaning water tank 19 and then send it to a plurality of inner cleaning rings 16 and cleaning nozzles 17 for spraying, directly flushing the internal impurities and dirt. The flushed impurities and dirt will flow out along the liquid outlet pipe 15 outside the outer sealing cylinder 7.

[0032] As Figure 1 , Figure 2 and Figure 3 shown, the embedded block 6 fixedly installed at the bottom of the outer sealing cylinder 7 is snap-fitted with the embedded groove 5 opened inside the freeze-drying tank 4. The embedded block 6 and the embedded groove 5 are used in cooperation, and the outer sealing cylinder 7 can be quickly installed through the embedded groove 5 and the embedded block 6. A fixing block 8 is fixedly installed outside the outer sealing cylinder 7, and a positioning bolt 9 penetrates above the fixing block 8. The fixing block 8 and the positioning bolt 9 can strengthen the stability of the connection between the outer sealing cylinder 7 and the upper table board 3. A fixing card slot 10 is opened inside the freeze-drying tank 4, and a fixing card block 11 is movably connected inside the fixing card slot 10. One end of the fixing card block 11 is fixedly installed with a material bottom tray 12. The structure of the material bottom tray 12 is simple and easy to operate. If a malfunction occurs, it is also convenient for maintenance personnel to replace and repair it in time without delaying the normal use of the device.

[0033] As Figure 1 , Figure 4 and Figure 5 shown, a manual telescopic rod 13 is fixedly installed above the material bottom tray 12, and an upper material tray 14 is fixedly installed at the top of the manual telescopic rod 13. According to the current size of the material, the manual telescopic rod 13 can be manually rotated to adjust the distance between the material bottom tray 12 and the upper material tray 14, so as to place materials of different sizes for freeze-drying work. The number of cleaning nozzles 17 is set to be multiple, and the multiple cleaning nozzles 17 are arranged in a circular array on the inner cleaning ring 16. The multiple groups of cleaning nozzles 17 are inside the outer sealing cylinder 7, and the internal impurities and dirt can be cleaned more cleanly.

[0034] Working principle of this utility model: First, take out this freeze dryer and connect it to the external power supply. First, remove the blockage from the cold air outlet in the freeze-drying tank 4, and then install the material bottom tray 12 and the upper material tray 14 on the freeze-drying tank 4 through the fixed card slots 10 and the fixed blocks 11. Then, according to the size of the current material, manually turn the manual telescopic rod 13 to adjust the distance between the material bottom tray 12 and the upper material tray 14, so as to place materials of different sizes for freeze-drying work. Then, after the materials are placed, quickly install the outer sealing cylinder 7 through the embedded groove 5 and the embedded block 6. The external fixed block 8 and the positioning bolt 9 can strengthen the stability of the connection between the outer sealing cylinder 7 and the upper platen 3. After the preparation work is completed in this way, the freeze-drying machine body 1 can be started, and the cold air is controlled by the display controller 2 to flow out from the freeze-drying tank 4 to carry out the freeze-drying work on the materials. When the materials need to be cleaned after freeze-drying, the materials can be taken out first, and the blockage at the cold air outlet in the freeze-drying tank 4 can be reinstalled to avoid the inflow of cleaning liquid. Then, the water supply pipe 22 can be connected to the external liquid inlet pipe 18, and then the switch of the pressurized water pump 20 is turned on to make the pressurized water pump 20 pump the liquid in the cleaning water tank 19 and send it to the multi-group internal cleaning rings 16 and the cleaning nozzles 17 for spraying. The multi-group cleaning nozzles 17 are inside the outer sealing cylinder 7 and can clean the internal impurities and dirt more cleanly. The impurities and dirt washed down will flow out along the liquid outlet pipe 15 outside the outer sealing cylinder 7. In this way, the labor intensity of workers is reduced in the whole process. Only the operator needs to dry the outer sealing cylinder 7, the material bottom tray 12 and the upper material tray 14 after cleaning. Finally, after completing all the installation and use work of the freeze dryer according to the above operations, turn off the switch of the pressurized water pump 20. If it is not used for a long time, cut off the external power supply. Just like this, the use process of this convenient-to-clean freeze dryer is completed.

[0035] Only some exemplary embodiments of the present utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
