Description

Technical Field

[0001] The utility model belongs to the technical field of tea making, and in particular relates to a vibration screening device. Background Art

[0002] Pu'er tea is a representative brand and characteristic industry of Yunnan, and is also a key component of Yunnan's tea industry. In recent years, based on rich germplasm resources, superior ecological environment and profound cultural heritage, the Pu'er tea industry has developed rapidly. Despite its resource advantages, it still faces many problems in the deep processing of Pu'er tea.

[0003] "Pile fermentation" is a process for making Pu'er ripe tea, and it is also a key process for forming and establishing the special quality of Pu'er ripe tea. The three dynamic forces of enzymes, microorganisms, and moisture and heat work together to cause the mutual transformation of substances in the leaves, especially the result of the auto-oxidation of polyphenols, thus forming the unique flavor of Pu'er ripe tea. The essence of pile fermentation of ripe tea is the action of microorganisms and enzymes: it is the combined action of extracellular enzymes and heat formed by microbial metabolism and the material metabolism of the microorganisms themselves that causes extremely complex changes in the substances contained in the tea leaves, forming the unique quality and taste of ripe tea.

[0004] Before pile fermentation, the dust and larger stone particles in the sun-dried green tea need to be removed, but now it is generally removed manually, which is relatively inefficient. Utility Model Content

[0005] The utility model aims to provide a vibration screening device, which can remove dust and larger stone particles in sun-dried green tea with high removal efficiency.

[0014] Furthermore, one end of the front sub-screen close to the opening and one end of the rear powder screen away from the opening are connected together through a connecting rod.

[0015] Furthermore, four vibration springs are provided, and the four vibration springs are fixed at four corners of the base.

[0016] Furthermore, two connecting frames are fixed to the lower side of the vibration frame, and the connecting frames include a first connecting rod and a second connecting rod. One end of the first connecting rod is fixedly connected to the lower side of the vibration frame, and the other end is fixedly connected to the second connecting rod. The first connecting rod is inclined from top to bottom away from the opening side, and one end of the second connecting rod away from the first connecting rod is fixedly connected to the lower side of the vibration frame. The second connecting rod is inclined from top to bottom toward the opening side, and a fixed connecting plate is fixed between the two second connecting rods, and the vibrator is fixed on the fixed connecting plate.

[0017] Furthermore, it also includes a receiving plate, which is fixed on the lower side of the vibration frame and is located below the vibration screen.

[0018] Furthermore, two vibrators are provided.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] (1) Place the sun-dried green tea on the vibrating screen, and the vibrator starts to vibrate, so that the sun-dried green tea on the vibrating screen vibrates, and the dust and larger particles of stone fall from the sieve holes after being screened, thereby filtering out the dust and larger particles of stone in the sun-dried green tea, and the screening efficiency is high;

[0021] (2) Since the vibrating screen is tilted downward toward the opening, when screening, first place the sun-dried green tea on the side of the vibrating screen away from the opening. In this way, the sun-dried green tea will gradually move toward the opening with the vibration, and be screened while moving until it moves out of the opening. The screened sun-dried green tea can be caught on the opening side to facilitate the next step of processing;

[0022] (3) When screening, first place the sun-dried green tea on the front sieve for screening. Since the vibrating screen is tilted downward toward the opening side, the sun-dried green tea that has been screened by the front powder screen will enter the rear sieve for secondary screening, making the screening cleaner.
