A continuous shaping system and control method for pearl tea based on automatic weighing

Abstract

The invention relates to a system and a control method for continuous shaping of pearl tea based on automatic weighing. The system includes a PLC control unit, initial frying unit, cooling unit, and re-frying unit. Automatic feeding is realized by setting vertical elevators, weighing conveyors, material distribution mechanisms, and vibrating conveyors in the initial frying unit and re-frying unit. , unloading, automatic pot re-frying, realize the continuous shape of pearl tea production, greatly improve the production efficiency and quality of pearl tea. The control method includes the control process of the initial frying and feeding link, the initial frying link, the spreading and cooling link, the second frying and feeding link and the second frying link, and the control method makes the above-mentioned shaping system more automatic.

Description

technical field [0001] The invention belongs to the field of tea processing equipment, and in particular relates to a continuous bead tea forming system based on automatic weighing and a control method. Background technique [0002] Pearl tea is a variety of green tea stir-fried green tea round green tea. The frying of bead tea is mainly completed by the double-pot curling machine, which mainly relies on the swinging frying plate to stir-fry the tea leaves in the pot, so that the tea leaves are gradually curled and formed into a spherical shape. At present, this type of machinery is produced by a stand-alone machine with a low degree of automation. It is mainly manifested in: it cannot be automatically weighed and loaded, and manual feeding is required during the processing process. The weight of the feeding is mainly estimated by experience, and the accuracy of feeding weight is not enough; Manual unloading is required after shutdown, and the machine cannot realize automat...

AI Technical Summary

Problems solved by technology

At present, this kind of machinery is produced by a single machine with a low degree of automation. The main performance is that: it cannot automatically weigh and load the material, and it needs to be manually loaded during the processing. It is necessary to manually unload the material after stopping the machine, and the machine cannot realize automatic discharge; in the process of mixing and re-frying, it is also carried out manually, and it is impossible to realize automatic mixing

This not only increases the labor intensity of the staff, but also has a large error in manual feeding, and it is impossible to quantitatively feed tea of ​​equal quality to multiple double-pot Quhao machines.

The unevenness of tea distribution seriously affects the quality of tea and the efficiency of production

The above problems hinder the application of this kind of machinery in the tea production line, resulting in the inability to realize continuous and automatic production of the pearl tea shaping process
