Description

A vibrating screening and processing equipment for tea production with controllable movement range

Technical field

The invention relates to the technical field of tea refining and processing, specifically a vibrating screening and processing equipment for tea production with controllable movement range.

Background technique

Since ancient times, Chinese people have a tradition of drinking tea. Tea has become one of the indispensable drinks in Chinese people's daily life. Drinking tea can refresh the mind, enhance memory, and help digestion. Tea is made by picking the buds or new leaves of the tea tree as raw materials and going through a series of production processes. The tea making process is: picking - withering - fermentation - finalization - Rolling-drying-(primary tea)-refining-processing-packaging. The appearance of primary tea is not good-looking and the quality is unstable. Therefore, in order to improve the quality of tea, it will be refined before sale. The basic steps of primary tea refining include screening, winnowing, cutting and rolling, sorting, and picking. Drying, blending, even stacking and boxing, etc.

Screening is the main operation of Maocha finishing technology. Any Maocha finishing process is related to screening technology, and screening can affect the quality. The purpose is to distinguish the length, thickness, and weight of tea leaves. Due to irregular factors such as the variety, season, and quality of raw tea leaves, there are uneven old and tender leaves, different length, roundness, thickness, and thin specifications, and the tendons, stems, base, slices, and A mixed phenomenon; at this time, the appearance and inner quality of the tea leaves should be further improved to better meet the needs of the consumer market. Therefore, the value of refined tea is much higher than that of Maocha, and the economic benefits of Maocha are best exerted.

When improving the appearance and internal quality of tea leaves, the raw tea leaves can be placed on the sifting machine, and the vibration of the sifting machine is used to make the tea strips jump up and down the screen surface. The tea that meets the specifications passes through the sieve holes and falls to the bottom of the sieve. The thick tea The strips remain on the screen surface, and the vibration of the screening machine can spread the tea strips placed on the screen surface evenly on the screen surface. Since the vibration amplitude of the screening machine is fixed, the vibration amplitude cannot be adjusted according to the production requirements when sifting tea; in addition, the shape of the tea strips During screening, some curly tea strips are easily stuck in the sieve holes and cannot fall out, which adds obstacles to tea screening.
