Description

Technical Field

[0001] The invention belongs to the technical field of osmanthus processing and relates to a drying device, in particular to a low-temperature vacuum anaerobic extraction dynamic drying device and a drying process for osmanthus. Background Art

[0002] Osmanthus is a plant. It can be used as a medicinal material and has medicinal value. At the same time, osmanthus can be used to make sachets, which have the effect of improving the smell in the air. Osmanthus needs to be processed before use. Different items made from osmanthus need to undergo different processing. In the process of making sachets, osmanthus needs to be dried. Drying can increase the shelf life of osmanthus. The drying of osmanthus requires the use of an osmanthus low-temperature vacuum anaerobic extraction dynamic drying device.

[0003] The patent application with publication number CN209246569U discloses a vacuum low-temperature drying device for sulfur-free dried osmanthus, comprising: a bottom plate, one end of an L-shaped bracket is fixed to the upper end of the bottom plate, the lower side of the other end of the L-shaped bracket is fixedly connected to the motor through a motor bracket, the motor is fixedly connected to the L-shaped bracket, the output shaft of the motor is fixedly connected to the middle of the horizontal block of the T-shaped block, the vertical block side of the T-shaped block is hinged to one end of a circular shaft, the other end of the circular shaft is fixed to the upper part of one side of the connecting block, the lower side of the connecting block is hinged to the horizontal axis of the U-shaped connecting block, and the two vertical rods of the U-shaped connecting block are fixedly connected to the upper side of the square block.

[0037] The sweet osmanthus to be processed is poured into the flip ring 201 from the inner feed port 3, and then the inner top cover 205 is covered. The flip ring 201 is driven to rotate by starting the motor 1 202. The rotation of the flip ring 201 drives the limit shaft 203 and the breaking rod 204 to rotate, and at the same time, the sweet osmanthus inside can be driven to rotate. The sweet osmanthus falls down after the flip ring 201 rotates to the highest point of the flip ring 201, and the sweet osmanthus falling from the high point inside the flip ring 201 falls on the breaking rod 204. The osmanthus hits the breaking rod 204, which can facilitate the breaking of the osmanthus, which is beneficial to the rapid drying of the osmanthus.

The bottom plate 501 can heat the internal space of the drying kettle 1 through the sealing plate 506. After the internal space of the drying kettle 1 is heated, the heat can be transferred to the inside of the turning ring 201 through the screening vents 4, which can facilitate the low-temperature drying of the turned sweet osmanthus flowers in the turning ring 201. At the same time, the impurity particles in the drying kettle 1 fall on the sealing plate 506 on the discharge port 6 due to their own gravity. By starting the fan 504, the air in the conveying pipe 503 flows, and the conveying The air flow inside the delivery pipe 503 drives the air flow inside the dust collection hole 8, and the air flow inside the dust collection hole 8 drives the impurity particles on the sealing plate 506 to enter the delivery pipe 503 through the dust collection hole 8.

The material unloading plate (1802) is located between the two telescopic rods (1801) and has a through hole (19) in the middle part which is sleeved on the outside of the conveying pipe (503). The telescopic end of one of the telescopic rods (1801) is fixedly equipped with a motor 2 (1803) whose output shaft is fixedly connected to the side wall of the material unloading plate (1802).

9. The osmanthus low-temperature vacuum anaerobic extraction dynamic drying device according to claim 8, characterized in that: The bracket (17) is provided with an osmanthus storage box (20) located below the blanking plate (1802).

10. A low-temperature vacuum anaerobic extraction dynamic drying process for sweet osmanthus based on the drying device according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: the motor 1 (202) drives the flipping ring (201) to rotate, and the flipping ring (201) drives the limit shaft (203), the breaking rod (204) and the osmanthus to rotate, the flipping ring (201) and the breaking rod (204) flip the osmanthus, and at the same time the screening vent (4) screens the impurities in the osmanthus, and the impurities fall into the drying kettle (1) through the screening vent (4) and onto the sealing plate (506) located in the discharge port (6); Step 2: while the turning ring (201) is rotating, the heating wire (502) is started, the heating wire (502) heats the bottom plate (501) through the installation cavity (7), the bottom plate (501) heats the inside of the drying kettle (1) through the sealing plate (506), after the space inside the drying kettle (1) is heated, the inside of the turning ring (201) is heated through the screening vents (4), and the osmanthus flowers inside the turning ring (201) are turned over and dried at a low temperature at the same time; Step three: At the same time, the fan (504) is started to drive the air flow in the conveying pipe (503), and the airflow in the conveying pipe (503) drives the air flow in the dust suction hole (8), and the impurities on the sealing plate (506) enter the conveying pipe (503) through the dust suction hole (8) along with the airflow, and the impurities in the conveying pipe (503) enter the impurity storage box (505) along with the airflow through the fan (504).
