Technical Field

[0001] The utility model relates to the field of traditional Chinese medicine processing, in particular to a sterilization and drying device for traditional Chinese medicine decoction pieces. Background Art

[0002] In the past, the sterilization and drying of traditional Chinese medicine decoction pieces mainly adopted the methods of natural drying and steaming. Natural drying relied on sunlight and air circulation to remove moisture and achieve a certain sterilization effect. However, this method was greatly restricted by weather conditions, with low efficiency and incomplete sterilization. For example, in some traditional Chinese medicine workshops, the traditional Chinese medicine decoction pieces were spread on bamboo trays and placed in the sun for drying. If there was rainy weather, the drying process would be delayed, and the decoction pieces might even become moldy. Although the steaming method could sterilize to a certain extent, it was easy to damage the effective components of traditional Chinese medicine, affecting the medicinal efficacy. Moreover, the operation was cumbersome and not suitable for large-scale production;

[0003] The prior art adopted a drum dryer, but the rotation of the medicinal materials in the drum would cause damage to the medicinal materials and loss of medicinal properties. The utility model solves the above problems. Summary of the Utility Model

The drying cylinder 1 is rotatably connected within a bearing frame 2. A end cover 3 is locked and fastened at the discharging end of the drying cylinder 1. Stirring rods 4 and discharging guiding vanes 5 are connected to the inner wall of the drying cylinder 1. The outside of the drying cylinder 1 is connected to power through a gear ring 6. Inside the closed end of the drying cylinder 1, a semi-cylinder one 7 and a semi-cylinder two 8 are rotatably connected. The semi-cylinder one 7 and the semi-cylinder two 8 are combined into a complete circle with one on top and the other at the bottom. The semi-cylinder one 7 and the semi-cylinder two 8 are respectively connected to the air outlet end and the air inlet end of a blower 9, and through holes are provided on the curved surfaces of the semi-cylinder one 7 and the semi-cylinder two 8;

[0020] Place the traditional Chinese medicine materials in the drying cylinder 1 and fasten the end cover 3. Turn on the heating element inside the drying cylinder 1 and turn on the power connected to the gear ring 6. The gear ring 6 drives the drying cylinder 1 to rotate. While the drying cylinder 1 is rotating, the heating element keeps working, and the circuit conduction can be achieved through a rotating conductive ring in the prior art. The drying cylinder 1 drives the stirring rods 4 to rotate. The stirring rods 4 stir the medicinal materials and lift them upward. Turn on the blower 9. The blower 9 sucks in the hot air from the lower part through the semi-cylinder two 8 and blows out the hot air upward through the semi-cylinder one 7. The medicinal materials lifted to the upper part are blown by the upward hot air, and the residence time in the air is greatly extended. While the drying effect is better, the impact received during falling is reduced, protecting the medicinal materials.

[0021] The semi-cylinder two 8 is connected to the air inlet end of the blower 9 through an elbow one 10, and a water absorption filter material 11 is provided inside the elbow one 10;

[0022] The water absorption filter material 11 adsorbs the steam, keeps the inside of the drying cylinder 1 airtight, and maintains the temperature inside the drying cylinder 1.

[0023] The semi-cylinder one 7 is connected to the air outlet end of the blower 9 through an elbow two 12. The lower surface of the elbow two 12 is connected to the fixed end of a cylinder 13.
