Tea rolling and shaping method and equipment

Abstract

The invention discloses a tea rolling and shaping method comprising the following steps: installing an extrusion bag capable of being extruded into a pressure container; dividing the inner space of the pressure container into a first space and a second space for hydraulic pressure by utilizing the extrusion bag, wherein the first space is used for containing tea; placing the tea to be rolled intothe first space; pumping liquid into the second space, and compressing and rolling the tea in the first space by means of the static pressure of the liquid; removing the liquid in the second space soas to relieve pressure, and scattering and loosening the tea in the first space by means of overturn or vibration; repeatedly pressurizing and reliving pressure at least one time; taking out the tea;and finishing the process of rolling the tea. The invention also discloses a tea rolling and shaping equipment. The invention has the advantages of simple structure, low construction cost, even rolling and shaping, convenient and safe operation, low labour intensity and high working efficiency.

Description

technical field [0001] The invention relates to a method for rolling and forming tea leaves and equipment used therein. Background technique [0002] In the production process of tea leaves, especially Tieguanyin tea leaves, after the tea leaves are greened (fried tea), it is necessary to knead and shape the tea leaves, that is, to squeeze and rub the tea leaves through pressure to promote the deformation and destruction of the tea leaves. , and the process of bending and shrinking the shape of the tea leaves into a pellet shape. In order to realize this process, the prior art adopts multiple mechanical equipment such as rolling-type speed-packing machines, flat-plate kneading machines, pendulum-type grinding disc forming machines, and hydraulic piston-type speed-packing machines (being called tea pressing machines) etc. recently. [0003] These devices use mechanical parts to crush or squeeze the tea leaves in some kind of motion. And these mechanical parts form pressure ...

AI Technical Summary

Problems solved by technology

And these mechanical parts form pressure and movement through various mechanical mechanisms such as gear transmission, screw push, hydraulic cylinder push, etc. The transmission, movement, and support system composed of many mechanical parts are complex, and the main body of the equipment is all moving equipment. Complex, large area, high cost

Judging from the effect of kneading and forming, tea bags in existing equipment are compressed by limited movement and tangible mechanical parts, and there is always a situation of uneven compression

Moreover, the prior art requires professionals to operate, which is time-consuming and labor-intensive, and accidents of pinching hands occur from time to time, and the convenience and safety of the operation are poor.

In addition, the kneading machine and the breaking machine of the prior art are completely separated, and the tea (package) can only be carried back and forth between the speed packing machine and the breaking machine manually, which significantly increases labor intensity and working hours
