Pu 'er tea automated management's pile storehouse

Technical Field

The utility model belongs to the technical field of tea production processing, a pile processing method is piled to tealeaves pile, especially a pile storehouse is piled to pu' er tea automated management is related to tealeaves.

Background

On the academic classification of tea products, ripe tea is classified as dark tea. The cooked tea is prepared by processing big-leaf sun-dried raw tea serving as a raw material through processes of pile fermentation and the like. Pile fermentation is a fermentation process in the process of making cooked puerh tea and is also a key procedure for determining the quality of the cooked puerh tea. The conventional operation of the pile fermentation process is as follows: firstly, uniformly wetting sun-dried green tea and stacking the green tea into a tea pile at a certain height; then covering the tea pile with covering materials such as hemp sheets and the like, and preserving the heat and moisture of the tea pile to ferment the tea under the action of damp heat. And when the temperature of the reactor core reaches a certain temperature and lasts for a certain time, deblocking and loosening, turning the reactor and cooling, and then forming the material pile again to continue pile fermentation. Repeating the steps for several times, and spreading for cooling and dehydrating to obtain cooked tea after the color and the content of the tea are converted to achieve the expected effect. The tea leaves in the pile fermentation gradually change from green to yellow, chestnut red and chestnut black along with the continuation of the pile fermentation process. The essence of the chemical changes of tea contents in the pile fermentation process is not clearly defined at present, and three expressions of enzymatic action, microbial action and damp-heat action exist in the tea science world, but the damp-heat action is generally considered to play a main role.

The tea after pile fermentation lacks luster before brewing, the color is dark chestnut during brewing, the color is uniform after brewing, and the leaf bottom is not elastic. From the color of the tea soup, the soup color of the pile tea product is from chestnut color to dark chestnut color, and the heavier the pile degree is, the darker the color of the tea soup is. From the taste, the pile-fermented tea has a special pile-fermented fragrance, the tea soup is smooth, the tongue surface has no special penetration, and no obvious level change.

At present, the piling mode used by most tea enterprises is mainly ground piling and is operated manually. The following outstanding problems exist:

1. the pile fermentation processing is carried out on the ground, the sanitary condition is poor, the tea material is easy to be mixed with sandy soil, small concrete blocks, rope ends, label strips, cigarette ends, fruit shells, chicken feathers, hair and other common ground impurities, the workload of picking the impurities in the subsequent refining processing is large, and the purity of the tea material is difficult to ensure.

2. The key parameters such as the moisture amount, the reactor temperature and the like are controlled by manual experience, the product quality fluctuation among batches is large, and the homogenization degree is not high.

3. The tea leaf wet water turning, mixing, piling, covering, pile turning and other work are all completed manually, the labor amount is large, and the labor intensity is high; and people frequently contact with the tea material, and hair, sweat and sole adhesive and the like easily fall into the tea material.

4. The manual stirring and pile turning mode is adopted, and a stirring tool and personnel trample to generate a large amount of broken tea materials. Statistics have been made by tea enterprises, and the breaking loss rate of tea in the pile fermentation link reaches more than 20%.

Some tea enterprises and scientific research institutions try to adopt a closed pot-type pile fermentation technology, the method solves the problem of sanitation, but completely abandons the advantages of the traditional pile fermentation method, the product quality is not ideal all the time, and adverse effects such as light tea flavor, sourness and the like sometimes occur. To date, such pile fermentation methods have not gained popularity and utility.

The feeding conveyor runs continuously; the conveyer belt of the reciprocating belt type distributing machine runs continuously, and the machine body does stepping reciprocating motion on the bracket. The two devices work cooperatively to realize continuous feeding of downstream devices. The feeding conveying equipment can be a belt conveyor, a vibrating conveyor or a lifting feeder. The machine body of the spreading machine reciprocates on a track above the pile fermentation bin, and automatic drill spreading of tea materials in the pile fermentation bin is realized through the cooperative match of a reciprocating belt type spreader.

The first process step: tea material stepping type continuous feeding

The feeding system consists of a feeding conveying device 5 and a reciprocating belt type distributing machine 8. Tea materials 4 are conveyed to a reciprocating belt type distributing machine 8 continuously through a feeding conveying device 5 along a material conveying direction 6 on a feeding conveyor and a material output direction 7 on the feeding conveyor, a conveying belt of the reciprocating belt type distributing machine 8 runs continuously along a conveying belt running direction 10 or 11 of the reciprocating belt type distributing machine, a machine body does stepping reciprocating motion on a support along a reciprocating direction shown by a machine body motion direction 9 of the reciprocating belt type distributing machine, and the spreading machine 12 is fed through the cooperative work of the two devices.
