Problems solved by technology

[0013] The purpose of the present invention is to solve the various defects of the existing energized coil electromagnetic heating type degreening machine, and proposes an electromagnetic degreening machine with variable magnetic field. Compared with the working mode of energized coil electromagnetic heating, it is fixed on the drum by the electromagnetic coil Surroundings, the conductor cutting magnetic field generates an AC voltage, which does not require excessive drum processing accuracy and additional brush devices. Compared with the working method of electric heating tube heating, it can alleviate the national power shortage, reduce production costs, save resources, and protect the environment.

Abstract

The invention discloses an electromagnetic fixation machine with a variable magnetic field. The machine comprises a driving motor, a frame, a first belt, a second belt, a roller, a shell, a spiral coil, a conductor, a permanent magnet, a permanent magnet fixing piece, a first driving belt wheel, a second driving belt wheel, a rotating disc, a supporting base and a reduction gearbox, the shell is horizontally arranged on the frame, the roller is sleeved by the shell, one end of the roller is provided with a driving shaft, and the outer side of the roller is provided with the spiral coil according to power requirements; the other end of the roller is provided with the conductor; and the permanent magnet fixing piece is fixed on the rotating disc, the rotating disc and the roller are coaxially arranged, the two permanent magnets are arranged at two ends of the permanent magnet fixing piece, and the N poles and the S poles of the two permanent magnets are arranged in opposite directions. The electromagnetic fixation machine adopts the permanent magnet as a stator, the driving motor drives the conductor attached to a roller as a rotor, the rotor continuously cuts different magnetic poles of the permanent magnet to generate alternating current, and the spiral coil is utilized to form a vortex electric field to heat the roller.

Description

technical field [0001] The invention relates to the field of green tea removal, more specifically, to an electromagnetic green removal machine with a variable magnetic field. Background technique [0002] The greening of tea leaves is one of the primary production processes of tea leaves. Its main purpose is to destroy and passivate the oxidase activity in fresh tea leaves through high temperature, keep the enzymes such as tea polyphenols in fresh leaves oxidized, and evaporate part of the water in fresh leaves, so that The tea leaves become soft, easy to knead and form, and at the same time emit green odor, which promotes the formation of good aroma. [0003] The current finishing technology is divided into two kinds of manual finishing and mechanical finishing. At present, except for a few well-known teas that use manual de-enzyming technology, most teas are de-enzymed by machinery. There are a variety of tea degreening machines on the market, including drum-type de-gree...
