Description

Technical Field

[0001] The utility model relates to the technical field of spray drying, and more specifically, to a low-temperature spray drying device. Background Art

[0002] Low-temperature spray drying is a device that atomizes liquid substances into fine particles through a sprayer and then dries them quickly under low-temperature conditions. It is a common drying technology that is suitable for heat-sensitive substances, drugs, food, cosmetics and other fields. For example, pig blood immunoglobulin is an immunoglobulin extracted from pig blood. Immunoglobulin is an antibody produced in humans and animals that can be used to treat and prevent certain diseases. Drying at low temperatures can effectively retain the activity and stability of immunoglobulin.

[0003] Among them, it was found through searching that the patent application number CN202223274672.0 discloses a low-temperature spray drying device for plant extracts, including a drying tower, the bottom of which is welded with a bottom plate through legs, and a centrifugal fan is fastened and installed at the edge of the top surface of the bottom plate;

[0004] When the structure is in use, a scraping mechanism is formed by setting a protective shell, a servo motor, a first shaft, a scraper plate, a second shaft, a first bevel gear, a second bevel gear, a connecting rod and a spiral blade. By starting the servo motor, the output end of the servo motor drives the second shaft to rotate. Since the second bevel gear of the first shaft is meshed and connected with the first bevel gear of the second shaft, the first shaft can drive the two scrapers to perform a large-scale circular scraping operation on the tower wall under the action of the connecting rod, and the spiral blades at the bottom of the first shaft can maintain the smoothness of the discharge end of the drying tower. Through the setting of the protective shell and the servo motor located on the outer wall of the drying tower, the adhesion of dry particles to the driving components can be reduced. However, when the structure is in use, it is not easy to divert materials of different particle sizes, which makes it difficult to divert materials when the structure is in use and not convenient enough when in use. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a low-temperature spray drying device, aiming to solve the problems raised in the above-mentioned background technology.

[0006] The utility model is implemented in this way. The utility model provides the following technical solutions: a low-temperature spray drying device, comprising a low-temperature dryer body, on which a flow guide drying component is arranged;

[0007] The diversion drying assembly includes a plurality of limit plates arranged side by side in the main body of the low-temperature dryer, and each of the limit plates is provided with a filter plate for filtering the material, and the plurality of filter plates are arranged side by side from large to small in aperture;

[0008] A controller is provided on the top of the low-temperature dryer body, an atomizing nozzle is provided inside the low-temperature dryer body, a pump located inside the low-temperature dryer body is provided on one side of the controller, and the top of the pump extends to the top of the low-temperature dryer body, a control button installed on the low-temperature dryer body is provided on one side of the pump, and the control button is detachably connected to the low-temperature dryer body, and a plurality of conduits for diversion are provided on one side of the surface of the low-temperature dryer body, and one end of each of the conduits extends to the input end of the pump.

[0009] It can be seen that in the above technical solution, the raw liquid is injected into the pump through the conduit, and the pump is started to transport it to the atomizing nozzle and sprayed out through the atomizing nozzle. The liquid substance is atomized into fine particles through the atomizing nozzle, and then quickly dried in a low temperature environment and passed through each filter plate. The pore sizes of the filter plates are arranged side by side from large to small, so that the low-temperature dryer body can reduce the thermal decomposition, oxidation and other reactions of the heat-sensitive substances while maintaining the activity and stability of the substances. In addition, during the drying process, it is also convenient to classify them, thereby improving the convenience of the device when in use.

[0010] Optionally, in a possible implementation, a pressure plate is provided on one side of the top surface of the low-temperature dryer body, the pressure plate is movably connected to the low-temperature dryer body through a shaft pin seat, a sealing gasket is provided on the side of the shaft pin seat facing the low-temperature dryer body, and an extension block is provided at the end of the shaft pin seat on the other side of the shaft pin seat, a limit handle for positioning is provided on the extension block, a locking block is provided on one side of the surface of the low-temperature dryer body, a locking hole threadedly connected to the limit handle is provided on the locking block, and a pressure gauge for pressure relief is provided at one end of the low-temperature dryer body;

The setting of the controller facilitates the control of the temperature of the low-temperature dryer body when in use, thereby improving the convenience of the device when in use.

[0012] Technical effects and advantages of the utility model:

[0013] By setting up the diversion drying component, compared with the prior art, the raw liquid is injected into the pump through the conduit, and the pump is started to transport it to the atomizing nozzle and sprayed out through the atomizing nozzle. The liquid substance is atomized into fine particles through the atomizing nozzle, and then quickly dried in a low temperature environment;

[0014] The pore sizes of the filter plates are arranged side by side from large to small, so that the low-temperature dryer body can reduce the thermal decomposition, oxidation and other reactions of heat-sensitive substances while maintaining the activity and stability of the substances;

[0015] In addition, during the drying process, the smaller the particles are and the larger the surface area, the faster the drying process can be, thereby quickly converting the liquid substance into solid powder, making it easier to classify the solid powder and increasing the convenience of the device when in use.
