Technical Field

[0001] The utility model relates to the technical field of production of traditional Chinese medicine lipid-lowering drugs, in particular to vacuum equipment for production of traditional Chinese medicine lipid-lowering drugs. Background Art

[0002] The main principle of the vacuum freeze dryer is to evaporate the water in the material through the vacuum drying process in a frozen state, thereby converting it into a dry product. This process involves three key factors: freezing, vacuum and heating. The purpose of freezing is to keep the material in a low-temperature state. The purpose of the vacuum is to extract the air around the material to create a vacuum state, and the heating is to heat the material through a heater so that the water evaporates. The vacuum freeze dryer is increasingly used in food, medicine, biological products, chemical industry and other fields, thanks to its ability to retain the original biological activity, physical structure and chemical properties of the material, and is especially suitable for the treatment of heat-sensitive substances.

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution: a vacuum device for the production of traditional Chinese medicine lipid-lowering drugs, including a drying barrel 1 and a vacuum pump 2. Legs 10 are fixedly connected to the bottom of the drying barrel 1. A variable-frequency condensation box 4 is arranged on the left side of the drying barrel 1. A condensation pipe 5 is fixedly connected to the top of the variable-frequency condensation box 4. The condensation pipe 5 is fixedly connected to the left side inside the drying barrel 1.

[0030] In this embodiment: By providing the heat-insulating cotton 11 on the outer side of the gas transmission pipe 304, when the water vapor passes through the gas transmission pipe 304, its temperature will not be reduced due to the conveying distance, resulting in a reduction in the defrosting efficiency.

[0031] As a technical optimization scheme of the present utility model, an exhaust port 12 is fixedly connected to the top of the drying barrel 1.

[0032] In this embodiment: After the defrosting is completed, the water vapor inside the barrel can be discharged through the exhaust port 12.

[0039] As a technical optimization solution of the present utility model, linkers 17 are bolted to the rear side of the front conveying bracket 8 and the front side of the rear conveying bracket 8 respectively.

[0040] In this embodiment: Through the linker 17, two or more conveying brackets 8 can be made to enter or pull out of the drying barrel 1 together. The linker 17 is bolted to the two conveying brackets 8, and a rotating shaft is provided in the middle for easy turning.

[0041] Working principle: First, the sliding rails 7 in the drying barrel 1 are docked with the sliding rails 7 on the production line, so that the conveying bracket 8 drives the drying tray 9 with materials to enter the interior of the drying barrel 1. The closing door 15 is rotated through the handle 16 to close the drying barrel 1. Then, cold air is conveyed to the condensing pipe 5 through the variable-frequency condensing box 4 and enters the drying barrel 1 to cool the materials preliminarily. After that, the drying barrel 1 is evacuated by the vacuum pump 2 so that the internal air pressure of the barrel reaches the vacuum standard to start the freeze-drying operation. After the operation is completed, the closing door 15 is opened, and the conveying bracket 8 close to the closing door 15 is pulled, and the inside of the barrel is pulled out together through the linker 17. Then the closing door 15 is closed, and the heating plate 301 is started to heat the stored water in the water storage crucible 302 to generate water vapor. Then, the water vapor is filtered and purified through the filter screen 14. After that, the water vapor is conveyed into the air pipe 304 by the air extraction pump 303, and the outside of the air pipe 304 is provided with a heat-insulating cotton 11 to keep the water vapor warm. After the water vapor enters the drying barrel 1, it can heat and melt the frost attached to the inner wall of the drying barrel 1. The melted water falls into the collection tank 305 through the mesh bag 13. Finally, the exhaust port 12 and the drain port 306 are opened to discharge the water vapor and the melted water, and the freeze-drying operation and the defrosting operation are ended.

[0042] The above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
