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

Abstract

The invention relates to a pinhead tea continuous shaping system based on automatic weighing and a control method thereof. The system comprises a PLC control system, a primary roasting unit, a spreading and cooling unit and a re-roasting unit, wherein a vertical lifting machine, a weighing conveyor, a material distribution mechanism and a vibration type conveyor are arranged at the primary roasting unit and the re-roasting unit for realizing automatic feeding, discharging and automatic pot combination re-roasting; the continuous shaping of the pinhead tea production is realized; the productionefficiency and the pinhead tea quality are greatly improved. The control method comprises the control processes of a primary roasting feeding link, a primary roasting link, a spreading and cooling link, a re-roasting feeding link and a re-roasting link. Through the control method, the automation degree of the shaping system is higher.

Description

technical field [0001] The invention belongs to the field of tea processing equipment, and in particular relates to a continuous shaping system and control method for pearl tea based on automatic weighing. Background technique [0002] Pearl tea is a kind of fried green tea with round fried green in green tea. The roasting of pearl tea is mainly done by a double-boiler machine, which mainly relies on a swinging frying board to stir-fry the tea leaves in the pot, so that the tea leaves are gradually curled and shaped, and finally formed into a ball. 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 combining and re-frying, it is also carried ou...
