Embodiment 1

[0026] Embodiment 1: as figure 1As shown, a tea processing system based on precise moisture control includes a constant flow feeding system, a processing system, and a moisture detection and control system. The constant flow feeding system is used to adjust or control the feeding amount and transportation speed of materials and maintain the amount of incoming materials. Constant, the feeding amount can be achieved through the unified cooperation of temporary storage and lifting devices, metering tubes and dynamic electronic scales. The transportation speed is controlled by the conveying mechanism, such as the conveying drive motor of the conveyor belt. The processing conditions include the processing temperature value of the processing system, The processing parameters related to moisture control in the processing system, such as the heating power of the processing machine, etc., make the processing parameters tend to be stable. The moisture detection and control system can in...

Embodiment 2

[0028] Embodiment 2: Take the finishing link as an example, such as figure 2 , image 3 As shown, a tea processing technology based on precise moisture control, when the material passes through the moisture detector on the conveyor belt before entering the greening system, the moisture detector obtains the real-time moisture content MC1 value of the material before entering the greening system and feeds it back to the controller ;When the material is discharged after finishing, when it passes through another group of moisture detectors, the moisture detector will obtain the real-time moisture content MC2 value of the material from the finishing system and feed it back to the controller; after the controller receives the MC1 value The intelligent algorithm judges whether the value of the real-time moisture content MC1 exceeds or is lower than the first preset value; after the controller receives the value of MC2, the intelligent algorithm judges whether the value of the real-t...

Embodiment 3

[0029] Embodiment 3: In actual use: a tea processing technology based on precise moisture control, which controls temporary storage and lifting devices, metering tubes, and belt conveyors by the controller to keep the incoming materials constant, and passes through the moisture detection signals before and after the processing machine. Then feed back to the processing machine and adjust the parameters of the processing equipment through the algorithm to ensure the stability and uniformity of moisture after processing. After the fresh leaves stand green, they pass through the temporary storage and lifting device, and are installed at the temporary storage and lifting device or at the exit of the conveyor. The photoelectric sensor sends out a signal to control the speed of the temporary storage and lifting device to lift the conveyor belt, and realize the automatic tea delivery flow. Control, there is a dynamic electronic scale under the metering tube, the material first falls fr...

Abstract

The invention provides a tea processing system and process based on accurate moisture control. The tea processing system comprises a constant-flow feeding system, a processing system and a moisture detection control system. The real-time moisture content of a material before entering the processing system and the real-time moisture content of the material after processing are obtained; whether thevalue of the real-time moisture content is higher than or is lower than a first preset value is judged; whether the value of the real-time moisture content is higher than or is lower than a second preset value is judged; and corresponding operation parameters of the processing system are adjusted based on the moisture content, so that the value of the real-time moisture content of the material which enters the processing system after being adjusted is always within the second preset value when the material exists the processing system. According to the invention, stability control of the processing technology is realized, and closed-loop control of the processing process is realized through real-time monitoring and management of the water content, so that the water content of tea leaves in the processing process is always kept in an ideal interval so as to obtain the best process control and processing quality.

Description

technical field [0001] The invention relates to the technical field of tea processing technology, in particular to a tea processing system and technology based on precise moisture control. Background technique [0002] During the processing of Pu-erh tea, according to the requirements of the process, fresh leaves need to be processed, and the control of water during processing is particularly critical, such as the step of killing greens, the step of fermenting in piles, and the step of tidal water in the process of pressing tea. Currently, The degree of processing is mainly judged by manual experience, and there is no real-time feedback and adjustment of equipment according to the incoming material situation to ensure the uniformity and stability of moisture after processing. [0003] In the finishing process, the quality of finishing directly affects the quality of finished tea. Greening is the most important process in the primary production of tea. How to improve its qua...
