Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a freeze-type dryer used for tea processing. Background Art

[0002] Tea processing is a delicate and complex process involving multiple links. Different types of tea (such as green tea, oolong tea, and black tea) require different degrees of fermentation or oxidation. The tea leaves after withering need to be dried to reduce the moisture content in the tea leaves and increase the shelf life and stability of the tea leaves. After other processing steps, tea leaves usually contain a certain amount of moisture. The working principle of the freeze dryer is to freeze the moisture of the tea leaves into ice by placing them in a low-temperature environment. This can effectively preserve the nutrients and natural aroma of the tea leaves at low temperatures.

[0003] Since a large amount of tea leaves need to be frozen, the tea leaves are often piled up on the surface of the shelf, that is, they are piled up and stored inside the freeze dryer for the subsequent freezing process. The tea leaves may form certain lumps inside the freeze dryer. These lumps may cause some tea leaves to be heated unevenly and the drying effect to be inconsistent, thereby reducing the production efficiency of the freeze dryer for tea processing. Therefore, a freeze dryer for tea processing is designed. Utility Model Content

Both sides of the two positioning rings 10 are provided with arc plates 11, and the bottom ends of the four arc plates 11 are provided with a plurality of tilting rods 12. The plurality of tilting rods 12 can respectively stir the tea placed on the surface of the shelving rack 6 to prevent the tea from sticking together and agglomerating during the condensation process. The tea can be dried more evenly by stirring, and the tea can be kept loose, which is conducive to uniform drying.

[0024] Example 2:

[0025] Based on the first embodiment, Figure 1 and Figure 4As shown, a torsion rod 14 is provided on one side of the two lifting cylinders 9, a plurality of recessed holes 13 are provided on the surface of the rotating shaft 8, and a running groove 16 is provided on the surface of the two shelving racks 6. The rotating shaft 8 moves inside the two running grooves 16. The utility model is a freeze-drying machine for tea processing. By providing an anti-drop plate 3, a heat dissipation panel 15, a recessed hole 13 and a torsion rod 14, the lifting cylinder 9 can move up and down at one end of the rotating shaft 8, thereby adjusting the position height of the arc plate 11. After the plurality of tilting rods 12 reach the appropriate position, one end of the torsion rod 14 is embedded in the corresponding recessed hole 13, and the two are threadedly connected.

[0026] Working principle: Tea processing is a delicate and complex process involving multiple links. Different types of tea require different degrees of fermentation and oxidation processes. After withering, the tea leaves need to be dried to reduce the moisture content in the tea leaves and increase the shelf life and stability of the tea leaves. After other processing steps, the tea leaves usually contain a certain amount of moisture. The working principle of the freeze dryer is to freeze the moisture of the tea leaves into ice by placing them in a low-temperature environment. This can effectively preserve the nutritional components and natural aroma of the tea leaves at low temperatures. Since the amount of tea leaves that need to be frozen is relatively large, the tea leaves often accumulate on the surface of the shelf rack 6, that is, they are stored inside the freeze dryer body 1 for subsequent freezing processes. The tea leaves may form certain clumps inside the freeze dryer. These clumps may cause some tea leaves to be heated unevenly and the drying effect to be inconsistent, which reduces the production efficiency of the freeze dryer for tea processing. To this end, the two shelf racks 6 are slidably installed inside the freeze dryer body 1. The top shelf rack 6 is supported by two positioning side plates 5. The rotating shaft 8 is located between the two running slots 16. After starting the servo motor 7, it drives the rotating shaft 8 connected to its output shaft to drive, thereby driving the The two lifting cylinders 9 rotate synchronously, and the arc-shaped plate 11 installed therewith also moves, which drives a number of tilting rods 12 to rotate. The tilting rods 12 can respectively stir the tea leaves placed on the surface of the shelf rack 6 to prevent the tea leaves from sticking together and agglomerating during the condensation process. By stirring, the tea leaves can be dried more evenly, keeping the tea leaves in a loose state, which is conducive to uniform drying and improves the production efficiency of the freeze dryer for tea processing. The lifting cylinder 9 can move up and down at one end of the rotating shaft 8, so that the position height of the arc-shaped plate 11 can be adjusted. After the tilting rods 12 reach the appropriate position, One end of the torsion rod 14 is embedded into the inside of the corresponding recessed hole 13, and the two are threadedly connected, so that the rotating shaft 8 and the lifting cylinder 9 can be limited and fixed. After the flip sealing door 2 is sealed with the freeze-drying machine body 1, one side of the two anti-drop plates 3 is respectively abutted against one side of the two shelving racks 6 to prevent the tea from falling out. During the drying process, the freeze-drying machine body 1 removes moisture from the tea by freezing and evaporation. This process will generate a certain amount of heat. The purpose of the heat dissipation panel 15 is to help effectively dissipate and discharge this heat to prevent the internal temperature of the equipment from being too high, which will affect the drying effect and equipment life.
