Problems solved by technology

[0004] In order to improve the problems of stacking odor in the above-mentioned prior art, how to effectively remove most of the stacking smell, how to solve the problem of difficult discharge after stacking, and realize the fully automatic processing of the stacking process as a whole is the purpose of the invention. After research and development, the human research and development team proposed a full-processing process, which can realize the automatic processing and continuous production of Pu-erh tea stacking links. Specifically, the present invention is realized in this way:

Embodiment 1

[0029] The fully automatic production and processing technology of Pu-erh tea in piles and air-drying includes the following steps:

[0030] Step S1, pre-treatment of tea raw material stacking: adjusting the moisture content of the tea material includes primary tide water and secondary tide water, ensuring that the moisture content of the tea material is controlled between 34% and 46%;

[0031] Step S2, storage and storage: tea materials are packed and transported into storage into a box-type fermentation warehouse for storage;

[0032] Step S3, stacking management: during the stacking process, intelligent sensors are used to obtain and adjust the stacking conditions in the stacking warehouse, and manage the time points and times of stacking in the stacking process; the intelligent sensors include temperature and humidity sensors, which are set at In the Wodui warehouse, it is uniformly monitored and processed by the controller to keep it in a state of constant temperature and...

Embodiment 2

[0037] On the basis of Example 1, preferably, in step S1, the primary dampening is tunnel-type dampening, and the moisture of the tea material is increased by 5% to 10%, so that the tea material is softened and softened, and the moisture content of the material after the initial dampening is obtained. Moisture content, after the second moisture regain, the moisture content of the tea material is precisely controlled between 20% and 25%.

[0038] The material box used in steps S2-S4 is a barreled material barrel with a detachable bottom plate, and several meshes or through holes are opened on the wall and bottom of the barrel; the material box used in steps S5-S6 is a square or rectangular material box.

[0039] Step S4 comprises the following steps: as image 3 As shown, the movable floor at the bottom of the barrel and the barrel body remain fixed and enter the discharging and unblocking station. After entering the station, they drive into the reversible and reversible convey...

Embodiment 3

[0056] On the basis of Example 1 or 2, the following steps are also included: the tea material is pre-steamed for 2-5 minutes; then the tea material is placed in a vacuum environment, and the ambient pressure is kept between 50-70kPa for a continuous 1-3 minutes; after step S2 is completed, inject negative pressure steam to contact the tea material, and keep the temperature of the negative pressure steam between 70-85°C for 1-3 minutes; or replace the negative pressure steam with hot air, inject The hot air with a temperature between 70-85°C is in contact with the tea material for 1-3 minutes; stop injecting steam or hot air, and gradually release the negative pressure until the standard atmospheric pressure is restored.

[0057] The specific steps of vacuum deodorization are as follows:

[0058] Step (1), pre-steaming the tea material before discharging and cooling after stacking or fermentation, the pre-steaming time is 1-5 minutes; the moisture content of the tea material a...

Abstract

The invention discloses a full-automatic Pu'er tea pile fermentation and airing production and processing technology. The technology comprises the steps of tea leaf raw material pile fermentation pretreatment, warehousing pile fermentation, pile fermentation management, pile turning, deblocking and discharging, vacuum impurity gas removal and tea material airing. The technical method and the operation process of automatic discharging are achieved in cooperation with mechanical equipment, so that the working procedure requirement that discharging is difficult to achieve from the charging container can be automatically completed through machinery, the discharging efficiency is improved, manual discharging operation is not needed, and time and labor are saved; the problems that caked and clustered materials are difficult to discharge completely and difficult to discharge are solved; an assembly line production automation mode of raw material preparation, water flushing, boxing, warehousing and pile fermentation, discharged material disintegration and pile turning, moisture regaining, warehousing and pile fermentation, discharged material deblocking, vacuum pile taste removal, spreading and airing, and discharged material warehousing of the Pu'er tea is realized on the whole, and an on-line automatic high-efficiency and high-quality Pu'er tea pile fermentation process is really realized.

Description

technical field [0001] The invention relates to an automatic process technology for the whole process of Pu'er tea stacking-turning-stacking-unblocking-spreading, in particular to a fully automatic production and processing process of Pu'er tea stacking-spreading. Background technique [0002] In the processing technology of cooked Pu-erh tea, the most critical link is the whole process from preparation for heaping to fermenting, turning over the heap, and drying. The heaping process is to artificially ferment Pu-erh tea naturally to achieve rapid aging the process of. The Wodui process seems simple, but it is very complicated. In the books and articles on Puer tea technology, it is simply summarized as "Wodui is to pile up the sun-dried green tea with water, cover it with sackcloth, and ferment it under the action of heat and humidity until it is transformed. craft". The emergence of the artificial stacking process is to meet the immediate consumption of Pu'er, shorten th...
