Description

Technical Field

[0001] This utility model relates to the technical field of tea processing equipment, and in particular to a tea residue screening device for tea processing. Background Technology

[0002] As a traditional Chinese beverage, the quality of tea processing directly determines the product's market value and drinking experience. Tea sieving is a crucial step in tea processing, primarily used to separate tea leaves and other impurities. With the large-scale development of the tea industry, mechanized sieving equipment has gradually replaced traditional manual sieving, effectively improving sieving efficiency and becoming an essential piece of equipment in modern tea processing.

[0003] Currently, most existing tea residue screening devices use screens with fixed apertures, separating tea leaves from residues through rotation. However, these devices have several drawbacks in practical applications. For example, firstly, the fixed aperture size prevents flexible adjustment based on the processing needs of different tea varieties and sizes, resulting in poor versatility. If different sizes of tea need to be screened, the equipment must be replaced, further reducing its practicality. Secondly, some screening devices lack effective protective structures, allowing dust generated from tea residues to easily disperse during screening, polluting the working environment and potentially being inhaled by operators, affecting their health. A search revealed that the technical solution provided by utility model application number CN202321150086.7 also suffers from the aforementioned problems. Utility Model Content

[0031] Those skilled in the art should connect all electrical components in this case to their compatible external power supply via wires, and should select a suitable controller according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0032] Working principle: During operation, open the box cover 10, then loosen and remove the pipe cap 7 on the feed pipe 6. Pour the tea leaves to be screened into the inner sieve cylinder 8 through the feed pipe 6 for storage. Tighten the pipe cap 7 and close the box cover 10. Then start the motor 3, driving the drive shaft 4 to rotate the outer sieve cylinder 5 and the inner sieve cylinder 8 as a whole. This causes the tea leaves to roll inside the inner and outer sieve cylinders 8 and 5. During this process, the tea leaves are separated through the sieve holes on the inner and outer sieve cylinders 8 and finally fall into the drawer 9 for storage. Simultaneously, the dust generated during separation is isolated by the box body 1 and the box cover 10, reducing the impact of dust on the working environment. If necessary, loosen the nut 16, and under the restoring force of the compressed spring 15, drive the pressure block 17 along the threaded column 13. The device moves outward, causing the pin 18 to disengage from the insertion hole 12, thus releasing the limiting effect between the inner screen cylinder 8 and the outer screen cylinder 5. Then, it pushes the pressure block 17 along the inside of the arc groove 11, causing the screen holes on the outer screen cylinder 5 and the inner screen cylinder 8 to misalign. After adjustment, the nut 16 is tightened again, causing the pressure block 17 to drive the pin 18 to insert into the corresponding insertion hole 12 at this moment, and compressing the spring 15, thereby limiting the position of the outer screen cylinder 5 and the inner screen cylinder 8 again. At this time, because the screen holes on the outer screen cylinder 5 and the inner screen cylinder 8 are misaligned, the sieving aperture of the device for tea leaves is changed, so that the device can be used to sift the broken tea leaves of various sizes. At the same time, the tea leaves that have already been sieving broken leaves can be sieving again according to the above steps. At this time, the size of the tea leaves can be separated, with the larger ones remaining inside the inner screen cylinder 8, while the smaller ones fall through the screen holes into the drawer box 9 for storage.
