Description

Keemun black tea refined automatic production line

technical field

The utility model relates to tea making equipment, in particular to an automatic production line for refining Keemun black tea.

Background technique

Tea refining, as the name implies, is to carry out fine processing on the basis of primary raw tea. The fresh leaves can be made into raw tea after primary processing and can be drunk. The purpose of refinement is to collect and blend raw tea from various places according to market requirements, and carry out post-processing to make it meet the sample grade requirements and product quality standardization. Specifically, the refined requirements are to classify grades, trim shapes, remove minor impurities, moderately dry, improve fragrance, and adjust quality. Tea refining is a very complicated work. Each single tea leaf generally needs to go through more than a dozen or more processes to ensure the quality of the final product. Each process requires complex processing in the processing equipment. Existing refining processes still rely on pure handwork, and existing refining equipment is independent of each other, that is, each process exists independently, and after one process is completed, the tea leaves need to be transferred to another process for processing. This method not only has extremely low processing efficiency, but also cannot guarantee the quality of the refined tea leaves, and has higher requirements for labor.

Drying is the first important process in the refining process of Keemun black tea, and it is also one of several key processes. Drying is mainly a process of evaporating and taking away the water in the tea raw materials by passing hot air into the tea raw materials. Its main purpose is to lose the water content of tea leaves, increase the aroma of tea leaves, etc. During the drying process, temperature is the main factor affecting the drying quality, and the heating effect is dominant, which plays a very important role in the formation of tea quality. , because the drying process is not only a process of dehydration and drying of tea leaves, but also a process of forming more chemical components and good aroma. Therefore, the drying effect directly affects the quality of tea.

Tea evenly stacking equipment is the equipment that mixes the dried tea leaves of each sieve according to the proportion into the finished tea that meets the standard sample. Heaper, drum-type tea even-heaper, automatic blending-type tea even-heaper, box-type tea even-heaper and silo-type tea even-heaper, among which driving-type tea even-heaper is used more. The driving-type tea evenly heaping machine is a tea evenly heaping machine that spreads tea by driving. It is composed of driving tea spreading belts, combining buckets, transmission pipes, etc. The number and size of the combining buckets are determined by the number of piles in each batch. When working, The teas of each sieve size to be blended are lifted and transported to the driving tea spreading belt on the top of the mixing bucket through the transmission pipe. The driving vehicle moves back and forth along the longitudinal direction of the mixing bucket, and the tea leaves on the tea spreading belt are continuously and evenly sprinkled layer by layer. After all the tea leaves are sprinkled in each bucket, open the door at the bottom of the bucket to let the tea fall down to achieve the purpose of mixing evenly. The multiple buckets of the leveling machine in the existing technology are not arranged in a straight line, which makes it impossible for the tea leaves to be transported by a conveyor belt after falling from the pile opening door, and manual assistance is required, which is relatively inefficient. Even pile effect is not good.

The tea processing equipment is basically made of steel materials, so there will be a lot of iron filings mixed in the tea during the tea processing process, which will seriously affect the quality of the tea and greatly reduce the grade of the tea, so the tea must be removed. Iron filings in the tea, especially in the production of high-grade tea, even very little iron filings are not allowed. The iron filings in the tea can be removed by screening and manual selection, but this method of removing iron The efficiency is low, the work intensity is high, and the iron removal effect of this method is not ideal in addition.

Screening can make the quality of the produced tea more uniform. Currently, the most commonly used screening technology in the tea processing industry often only uses one standard to screen tea, which results in uneven thickness of tea raw materials after screening. , There are many impurities, which greatly reduces the impurity removal rate, and also increases the difficulty of processing in the later process.

After sieving, the tea leaves need to be subpackaged. When subpackaging, it is necessary to ensure that the quality of each subpackaged tea leaves is equal, at least not too different, so the tea leaves must be weighed first. In the prior art, the tea leaves are generally weighed. The artificial method is very inefficient and wastes a lot of manpower.
