Temperature control tea leaf roller continuous enzyme-deactivation machine

Abstract

The invention discloses a temperature control tea roller continuous enzyme-deactivation machine, which comprises a furnace body, a roller arranged in the furnace body and a heating device for heating the roller, wherein the heating device comprises a plurality of normally-open heating units which are normally open in an enzyme-deactivation process and a temperature control heating unit which can be opened and closed in the enzyme-deactivation process. According to the invention, according to a principle that starting current is more than rated current and rated current is more than running current, the heating units are divided into the normally-open heating unit and the temperature control heating unit, so that the problems that in the existing temperature control technology, installed power is all controlled by the temperature control device, the temperature controller is frequently started and closed, electric energy is in a frequent starting current state for a long time, the pot temperature fluctuation range of the enzyme-deactivation machine is large, and the energy consumption is increased are solved.

Description

technical field [0001] The invention relates to a tea greening machine, in particular to a tea roller continuous greening machine which is convenient for temperature control. Background technique [0002] At present, in the domestic tea processing industry, the automation and cleaning of mechanical equipment has become a trend. Coal (firewood) for processing machinery has been replaced by clean energy such as electric energy and gas, especially electric energy with the highest degree of cleanliness. The continuous greening machine has been popularized in the domestic tea processing industry. There are two electric heating methods, one is electric heating material furnace cavity heating; the other is direct heating by electromagnetic induction drum. There are two methods of temperature control. One is the fixed (normally open) electrical power according to the model layout of the mechanical equipment, that is, after the power is turned on, all the electrothermal materials wi...

AI Technical Summary

Problems solved by technology

This method is affected by the peak and valley periods of the power line and the changes in the electric energy load of the workshop, and the temperature of the greening machine pot is extremely unstable; the second is to set up a temperature control device according to the electrical power required by the layout of the mechanical equipment model, and all the electric heating materials pass through the temperature control. When the temperature is higher than the set value, all power is turned off; when the temperature is lower than the set value, all power is turned on

Although this method avoids the impact of the peak and valley periods of the power line and the changes in the power load of the workshop, the thermostat is frequently turned on and off, and the electric energy is out of the frequent starting current state for a long time, and the temperature of the greening machine fluctuates greatly.
