Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea processing technology, and in particular to a dustproof green tea cooling rack. Background Technology
[0002] The spreading of fresh leaves is an important step in the initial processing of green tea. After picking, the fresh leaves need to be spread in a ventilated place to evaporate some of the moisture, making the leaves soft and releasing the grassy smell. This creates favorable conditions for the effective inhibition of enzyme activity and the formation of the tea's appearance and internal quality in the subsequent fixation process. Furthermore, the timely cooling of the tea leaves after fixation and drying is also an important step in the green tea processing, laying the foundation for the formation of the clear tea soup and green leaves.
[0003] However, existing green tea cooling racks have shortcomings in use. First, they lack a structure to protect against dust, leaving fresh leaves exposed and prone to accumulating dust and impurities, resulting in poor cleanliness. Second, during the cooling process, the tea leaves often pile up and bulge within the rack, leading to poor drying in certain areas and affecting the quality of the finished tea. Therefore, a dustproof green tea cooling rack is proposed to address these issues. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a dustproof green tea cooling rack, which aims to improve the existing green tea cooling racks that lack a structure to block dust. When the fresh leaves are cooled, they are exposed and their surfaces are easily covered with dust and impurities, resulting in poor cleanliness. In addition, during the cooling process, the tea leaves in the rack often pile up and bulge, which leads to poor dehydration of some tea leaves and affects the quality of the finished tea.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dustproof green tea cooling rack, comprising a frame body, wherein several outer rails are fixedly connected to both sides of the inner wall of the frame body, and inner rails are slidably connected to the inner walls of two outer rails at the same height, and a slide block is installed at the bottom end of each of the two inner rails, a sliding component is installed on the inner wall of the slide block, a perforated frame is installed between the two sliding components, and a vibration motor is fixedly installed on both sides of the bottom end of the perforated frame, a ventilation component is installed on the rear side of the frame body, and a door cover is hinged to the front side of the frame body;

A fan is fixedly installed in the middle of the rear side of the fabric cover, and the output end of the fan is connected to the interior of the fabric cover. Several air outlets are evenly provided on the inner wall of the frame near the fabric cover.
[0007] As a further description of the above technical solution:
[0008] The sliding assembly includes a slider and two support springs. The slider is fixedly connected to one side of the perforation frame and is slidably connected to the inner wall of the slide block. Support springs are fixedly connected to both sides of the inner wall of the slide block, and one end of each of the two support springs is fixedly connected to both ends of the slider.
[0009] As a further description of the above technical solution:
[0010] Several ventilation openings are provided on both sides of the frame, and the inner walls of the ventilation openings are fixedly connected with side dustproof nets.
[0011] As a further description of the above technical solution:
[0012] A front dustproof net is fixedly connected to the surface of the door cover.
[0013] As a further description of the above technical solution:
[0014] A filter screen is engaged at the input end of the fan.
[0015] As a further description of the above technical solution:
[0016] Electromagnets are fixedly installed on one side of the inner wall of the frame corresponding to the ends of several outer rails, and an iron plate is fixedly connected to one end of the inner rail.
[0017] As a further description of the above technical solution:
[0018] The electromagnet is magnetically connected to the iron sheet.
[0019] As a further description of the above technical solution:

Multiple perforated frames 12 are distributed vertically to process green tea leaves in batches for cooling. Dustproof nets are installed on the side ventilation openings 3 and the front door cover 2 of the cooling rack to meet ventilation requirements while preventing dust from entering. The fan 16 at the rear of the cooling rack can be turned on, and the outside air is filtered by the filter screen 17 to remove dust and impurities before being introduced into the air distribution shell 15 and then discharged from several air outlets. The air is evenly blown into the cooling rack at 18 points to promote air circulation, thereby effectively reducing the moisture content of the tea leaves while preventing dust and impurities from entering and improving the cleanliness of the tea leaves. By activating the electromagnet 7 to attract the iron plate 13 at the end of the inner rail 8, the position of the slide 9 can be restricted. Then, the vibration motor 14 at the bottom of the perforation frame 12 is activated. With the cooperation of the slide bar 10 and the support spring 11, the perforation frame 12 can be moved back and forth, thereby flattening the raised green tea leaves in the frame, making the dehydration process more uniform and ensuring the quality of the finished tea leaves.
