Continuous kneading production line of differential cone spiral kneading push type oolong tea

Abstract

The invention discloses an oolong tea continuous kneading production line of differential cone screw kneading and propelling type. Existing oolong tea kneading force control relies too much on operator experience. The screw barrel and the tapered screw shaft of the present invention rotate at differential speeds; the external thread crests of the tapered screw shaft and the internal thread tops and bottoms of the screw barrel are alternately opposed to form a large and a small cavity alternately, so that the tea leaves are placed in the screw barrel. While advancing in the axial direction, it is accompanied by radial movement; the space between the cone screw shaft and the screw barrel changes from large to small along the direction from the input end to the output end of the screw barrel. With the continuous rotation of the screw barrel and the cone screw shaft, the tea leaves are rolled and twisted. When the tea leaves are closed, the kneading force gradually increases, so that the tea leaves are spiraled into strips and shaped by rolling; when the tea leaves travel to the output end of the spiral barrel, the edges of the pressing plate play a role of kneading and provide irregular pressing force; the control module sends the pressure sensor signal Compared with the preset kneading force, control the recycle speed and kneading force. The invention realizes continuous rolling of tea leaves and has good rolling effect.

Description

technical field [0001] The invention belongs to the technical field of oolong tea processing, and specifically relates to a differential-speed cone-spiral kneading and propelling oolong tea continuous kneading production line. The core part adopts a cone-screw shaft and a spiral barrel to carry out differential-speed spiral kneading and forming of tea leaves, which is helpful for the formation of oolong tea. Granular shape that meets the requirements. Background technique [0002] The processing of oolong tea mainly goes through the processes of withering, greening, roasting, rolling, speed bagging, bagging and drying; among them, rolling is the shaping process of the initial production of oolong tea, which is processed by a rolling machine and relies on external forces to make the tea leaves Kneading becomes lighter, rolling into strips, forming its tight and curved shape; at the same time, part of the tea juice is squeezed and attached to the surface of the leaves, which a...

Problems solved by technology

Kneading is the most labor-intensive, time-consuming, and energy-intensive process in the processing process. The control of kneading force depends too much on the experience of the operator, especially for operators who lack experience. The material quality is uneven and the processing effect is not ideal, which affects the product quality and cannot guarantee the consistency of product quality

The entire processing process requires a lot of manpower and material resources, which is time-consuming and labor-intensive and cannot be operated continuously. The processing efficiency is low, and it does not meet the development vision of the new era of manufacturing that is environmentally friendly, efficient and sustainable.
