Embodiment 1

[0023] See Figures 1 and 2. The electromagnetic drum cleaning machine of the present invention consists of a steel cylinder 1, a heating coil 2, a heat insulating material 3, a decorative plate 4, a guide wheel 5, a far-infrared temperature sensor 6, a transmission device 7, a frame 8, an electric control cabinet 9, and guide vanes The outer layer of the steel cylinder 1 is covered with a heating coil 2, the inside of the steel cylinder 1 is welded with a guide vane 10, and the outer layer of the heating coil 2 is wrapped with a heat insulating material 3, and the outermost layer is passed through The decorative plate 4 fixed on the frame 8 by screws forms the main structure of the electromagnetic drum cleaning machine. The guide wheel 5 is connected with the transmission device 7, and the two are connected by a chain 11 to realize the transmission of power from the transmission device 7 to the main structure. , to promote the rotation of the steel cylinder 1, the transmission...

Embodiment 2

[0026] Referring to Fig. 1, during actual operation, during the rotation of the drum 1, the temperature of the three sections of the steel drum 1 can be set respectively through the main control cabinet 9, and the temperature of the three sections of the steel cylinder 1 can be set through the far-infrared temperature sensor 6 of each section. Monitor and feed back to the electric control cabinet 9 to realize the precise control of the temperature of the three sections of the steel cylinder 1 to meet the needs of fresh leaves of different varieties and tenderness.

Embodiment 3

[0027] Embodiment 3 comprehensive performance comparison:

[0028] 1. Taking the drum-type greening equipment as an example, comprehensively compare the performance differences of different heating methods:

[0029] heating

[0030] heating

[0031] 2. Combining electromagnetic heating technology with far-infrared temperature measurement technology, compared with the combination of traditional secondary heating and thermocouple temperature sensing technology, it can not only increase the heat conversion rate by about 30% in the heating link, but also because of the use of far-infrared temperature measurement Technology, more rapid and more accurate response to the temperature of the heated object, narrowing the temperature fluctuation range of the heated object, so that energy can be saved by 1-5% in the temperature control link. In addition, the organic combination of electromagnetic heating and far-infrared temperature measurement enables precise temperat...

Abstract

The invention provides a heating and temperature detecting method in tea processing, which applies electromagnetic heating and far infrared temperature detecting, wherein the electromagnetic heating comprises thermal insulation material, a heating coil, a magnetic conductive object and the like, and the far infrared temperature detecting comprises a far infrared temperature sensor and a temperature display device or a control device. The invention provides an electromagnetic roller steaming machine which consists of a steel cylinder, the heating coil, the thermal insulation material, a decorating plate, a guide pulley, the temperature sensor, transmission device, a stander, an electronic control cabinet and a guide vane strip; and the steel cylinder is heated in a way of electromagnetic heating, and the temperature of the steel cylinder is monitored in real time by the far infrared temperature sensor. The method has high energy conversion efficiency, little unavailable energy loss and no smoke and harmful gas emission, greatly reduces the air temperature of a workshop, and improves the work environment of the workshop; and furthermore, the method is sensitive and rapid in temperature response, can effectively reduce the fluctuation range of the temperature of the steel cylinder, is beneficial to accurately adjusting and controlling the electronic control cabinet, effectively improves the quality of enzyme-denatured leaves, and is even in deactivation of enzyme. Therefore, tea has obvious aroma and emerald green color.

Description

technical field [0001] The invention belongs to the field of tea processing, and relates to a tea processing method, in particular to a method for heating and measuring temperature in tea processing. Background technique [0002] The essence of tea processing is to use fresh leaves as raw materials, and use artificial means to make the water in the fresh leaves gradually lose until it reaches a specific limit. This process is accompanied by a series of complex physical and chemical changes such as the decomposition and transformation of endoplasmic components, and finally forms the specific flavor quality of tea. In production and processing, the heat treatment of tea in-process is an extremely important content. Processes such as greening, stripping, and drying all involve high-temperature treatment, which has a significant impact on the quality of the final finished tea. [0003] At present, the heating methods of tea processing machinery mainly include wood burning, coal...
