Multilayer multi-line nature-imitated synchronous withering device used for processing black tea

Abstract

The invention provides a multilayer multi-line nature-imitated synchronous withering device used for processing black tea, which comprises a machine frame, an air inlet, an air outlet and a draught fan. The invention is characterized in that the machine frame is made into a structure of a multi-line cabinet type withering frame, the middle parts of the cabinet type withering frame are withering chambers, a multilayer drawer type placing frame is arranged in each line of the withering chamber, a withdrawable drawer type drying sieve is movably arranged in each layer of the drawer type placing frame, air inlet openings are arranged at the periphery of the bottom under the cabinet type withering frame, a plurality of wet air collection covers are arranged on the top above the cabinet type withering frame, exhaust pipelines at equal intervals are connected at all outlet openings of the wet air collection covers, and windward machines are arranged at public outlet openings of the equal distance exhaust pipelines. The invention can prepare good fermentation conditions for the fermentation work procedure after the beginning of kneading and entwisting, and has the advantages of reasonable structure, easy regulation and control, small area of occupied ground, high yield (the tea green processing amount of one withering machine can be used for six kneading and entwisting machines) and no influence by climatic elements. Each layer of fresh leaves has equivalent and uniform wind exertion and water removal, ideal effects such as sanitary produced tea, high yield, good quality and the like can be reached, and the invention is applicable to the withering processing of Fujian Tanyang Kung Fu black tea and black tea of other varieties.

Description

1. Technical field [0001] The invention relates to a tea product processing machinery, in particular to a multi-layer and multi-row imitation natural synchronous withering device for processing black tea of ​​the genus "Tanyang Gongfu" or black tea of ​​the genus Oolong. 2. Background technology [0002] People in the tea industry know that many fermented teas (or non-fermented teas), especially the first process in the production and processing of black tea, are withering. Withering, the moisture of raw tea leaves is slowly and continuously dissipated. Naturally withered tea leaves are of particularly high quality, but the beach covers a large area, inevitably biting by mosquitoes and flies and scattered dust, and is greatly affected by weather and environmental factors, such as continuous cloudy and rainy days, humid and cloudy days, and windless days. Tea leaves wither time is long and yield is low, and quality can't be guaranteed, also has a strong impact on withering q...

AI Technical Summary

Problems solved by technology

Naturally withered tea leaves are of particularly high quality, but the beach covers a large area, inevitably biting by mosquitoes and flies and scattered dust, and is greatly affected by weather and environmental factors, such as continuous rainy days, humid cloudy days, windless days, The withering time of tea leaves is long and the yield is low, the quality cannot be guaranteed, and the quality of withering is seriously affected;

Drying by sunlight directly affects the tea leaves, which requires manual continuous drying. Otherwise, the temperature will vary, which will easily cause the tea leaves to die green, uneven water flow, heavy bitterness, and mosquito bites, dust scattered and affect the quality of tea; 3. Air conditioning Water sieve withering, although the temperature can be controlled, still has the disadvantages of large floor space, high energy consumption, and low yield; The quality of tea is not as good as natural withering

[0003] In order to improve the yield and quality of withering, so as to achieve good physical and biochemical withering effects, tea processing industry or scientific research personnel from all over the world have developed many tea withering machines, and applied for Chinese patents: including: tea fast withering machine (Patent No. 94202626.8), tea leaves withering automatic drying device (patent No. 200720008033.6), a kind of tea withering treatment equipment (patent No. 200720006387.7), tea automatic withering device (patent No. 200720008218.7), etc., these above-mentioned withering machine devices mostly adopt sprocket chain conveyor belt The power drive mechanism has the advantages of saving space, no mosquito bites and dust pollution, hygienic and clean, high withering efficiency, large output, etc., but it also has the advantages of high energy consumption, complicated assembly and daily maintenance. In addition, using the above-mentioned withering equipment Artificial withering of tea greens is still difficult to guarantee superior withering quality, and there is still a considerable gap compared with natural withering, because the quality of withering will be affected by temperature, humidity, thinning thickness of fresh tea leaves, withering time, etc. The influence of many factors such as the gradual dehydration speed of tea green
