Description

Technical Field

[0001] The utility model relates to the technical field of green tea processing, in particular to green tea processing and grinding equipment. Background Art

[0002] Green tea is one of the main types of tea in China, and its characteristics are clear soup and green leaves. Green tea powder is a product made by processing green tea leaves into powder. This can greatly improve the utilization rate of tea, because powdered tea leaves can be more easily dissolved in water, thereby releasing more beneficial ingredients such as tea polyphenols, caffeine, amino acids, etc.

[0003] In the process of green tea grinding, the tea leaves are crushed and ground, which will produce a lot of fine particles and dust. The fine parts of the tea leaves and the dust will be dispersed with the air flow. These dusts will not only affect the operating environment, but also may have a negative impact on the taste and quality of the green tea powder. In the process of green tea processing and grinding, dust collection is a very important step, which is of great significance to improving the purity and quality of green tea powder. The dust collection operation can be achieved through special dust collection equipment, which can effectively collect these fine dust and tea fragments, thereby keeping the operating environment clean and hygienic. In addition, dust collection can also prevent the green tea powder from being contaminated, ensuring its purity and quality.

[0004] In the prior art solution, the vacuum cleaner matched with the grinding equipment generates a strong airflow through air pump adsorption, and the airflow forms a negative pressure inside the vacuum cleaner. Due to the effect of the negative pressure, the air near the vacuum cleaner is sucked into the equipment. The vacuum cleaner is usually equipped with a filter. When the air and dust mixture passes through the filter, the dust and fine particles are intercepted on the filter, and the air is discharged to the outside of the equipment through the filter. However, the filter in the vacuum cleaner needs to be cleaned regularly. If the dust and fine particles attached to the filter cannot be cleaned in time, the overall vacuuming effect and filtering effect will be affected. Summary of the invention

[0005] The purpose of the utility model is to provide a green tea processing and grinding device, which can ensure that the fine parts of tea leaves and dust are fully adsorbed by timely cleaning of the filter screen, thereby ensuring the taste and quality of green tea powder, so as to solve the problems raised in the above-mentioned background technology.

[0032] By adopting the above technical solution, when the grinding cylinder 1 is grinding, the dust suction pump 203 is started, and the dust suction pump 203 is connected with the inside of the dust suction box 202, so that negative pressure can be formed inside the dust suction box 202, so that the fine tea leaves and dust generated inside the grinding cylinder 1 can be adsorbed through the dust suction box 202 and the dust suction pipe 204. When the adsorbed fine tea leaves and dust mixture passes through the filter 205, the dust and fine particles are intercepted on the filter 205, and the air is discharged to the outside of the dust suction box 202 through the filter 205 by the dust suction pump 203.

[0033] Specifically, Figure 1-Figure 3 As shown, the output end of the driving shaft 8 is located below the driving groove plate 901 and is provided with a grinding assembly 7. The grinding assembly 7 includes a driving disc 701 fixed to the output end of the driving shaft 8. Three grinding pressure plates 706 are fixed to the lower end surface of the driving disc 701. A brush head 705 is fixedly installed at one end of the grinding pressure plate 706 away from the driving shaft 8. A plurality of grinding balls 704 are also embedded in the lower end surface of the driving disc 701. Three feeding holes 702 are opened inside the driving disc 701. A driving rod 703 is fixedly installed on the inner wall of the grinding cylinder 1, and the driving rod 703 is fixedly installed on the inner wall of the grinding cylinder 1. The lower end surface of 03 fits with the upper end surface of the driving disk 701, and a discharge pipe 5 corresponding to the lower end surface of the driving disk 701 is pierced on the inner wall of the grinding cylinder 1. A screening net 51 is embedded in the end of the discharge pipe 5 close to the grinding cylinder 1. The bottom end of the driving shaft 8 is connected to the grinding bottom plate 6 through a differential, so that the grinding bottom plate 6 can be driven to rotate. The rotation speed of the grinding bottom plate 6 and the driving disk 701 are different. In this way, the green tea can be ground between the grinding bottom plate 6 and the driving disk 701. A feed valve pipe 4 is fixedly pierced on the upper end of the grinding cylinder 1.

[0034] By adopting the above technical solution, the semi-finished green tea powder that has undergone preliminary processing is introduced into the grinding cylinder 1 through the feed valve tube 4, and the semi-finished green tea powder can be accumulated on the driving disk 701. The rotation of the driving disk 701 can make the semi-finished green tea powder evenly enter the driving disk 701 and the grinding bottom plate 6 through the three feed holes 702. The setting of the driving rod 703 can avoid the accumulation of green tea at the feed hole 702. The rotation speeds of the driving disk 701 and the grinding bottom plate 6 are different. The rotation of the driving disk 701 can drive the grinding pressure plate 706 to rotate. The grinding pressure plate 706 grinds the green tea between the grinding bottom plate 6 and it.

At the same time, the green tea powder accumulated at the screening net 51 can be scraped to other positions by brushing, so that the green tea powder can be ground again.

[0035] Working principle: When in use, the semi-finished green tea powder that has undergone preliminary processing is introduced into the grinding cylinder 1 through the feed valve tube 4, and the semi-finished green tea powder can be accumulated on the driving disk 701. The rotation of the driving disk 701 can make the semi-finished green tea powder evenly enter the driving disk 701 and the grinding bottom plate 6 through the three feed holes 702. The rotation of the driving disk 701 can drive the grinding pressure plate 706 to rotate, and the grinding pressure plate 706 grinds the green tea located between the grinding bottom plate 6 and it. At the same time, the grinding balls 704 can rotate under the action of the grinding pressure plate 706, and the double grinding of the green tea is achieved through the contact between the grinding balls 704 and the green tea. The fully ground green tea powder can be discharged through the discharge pipe 5. When the cylinder 1 is grinding, the dust suction pump 203 is started, and the dust suction pump 203 is connected with the inside of the dust suction box 202, so that negative pressure can be formed inside the dust suction box 202, so that the fine tea leaves and dust generated inside the grinding cylinder 1 can be adsorbed through the dust suction box 202 and the dust suction pipe 204. The servo motor 3 can drive the drive shaft 8 to rotate, and the drive shaft 8 can drive the drive groove plate 901 to rotate. There are embedded balls 909 sliding in the groove ring in the drive groove plate 901. The embedded balls 909 slide in the groove ring from deep to shallow, so as to push the connecting rod 906 to move. The extension of the connecting rod 906 can push the cleaning frame 907 to move, and the brush 908 installed on the cleaning frame 907 can brush the filter 205 to move.
