A microwave heating device and operation method for automatic material feeding and discharging

Abstract

The invention belongs to the technical field of food heating equipment and provides a microwave heating device allowing automatic feeding and discharging and an operating method. The microwave heating device comprises a drive control circuit, a main heating circuit, an automatic feeding device, an inlet sensor, a heating chamber, an automatic discharging device and an outlet sensor. The automatic feeding device, the main heating circuit and the automatic discharging device are connected with the drive control circuit respectively. The automatic feeding device comprises a feeding channel, a counterweight block, a counterweight seal plate and a balance plate. The heating chamber comprises a heating box, cooling thin holes, a magnetron, a heating base plate, a reset hole, a cooling fan, a thermocouple, a waveguide, a rotating disc motor and a transformer. The automatic discharging device comprises a bottomless pushing plate, a push rod motor, an electric push rod, an outlet door, a discharging channel, a discharge port and two reset monitoring switches. The microwave heating device has the advantages that manual operation is not required, working efficiency is high, time and labor are saved, and full-automated working is achieved.

Description

technical field [0001] The invention belongs to the technical field of food heating equipment, and in particular relates to a microwave heating device and an operation method for automatic material feeding and discharging, which are convenient for staff to replace inventory, convenient for consumers to operate, and low in failure rate. Background technique [0002] With the development of society, people's requirements for living standards are getting higher and higher. In order to ensure food hygiene, most foods need to be heated before eating; at present, household microwave ovens are the most widely used in the field of food heating, which can increase the heating speed of food, but the preparation work before and after heating needs to be done manually , there is a low degree of automation, the problem of troublesome operation. [0003] The core of the existing household microwave heating technology is to rely on the magnetron to generate high-frequency electromagnetic ...

AI Technical Summary

Problems solved by technology

[0003] The core of the existing household microwave heating technology is to rely on the magnetron to generate high-frequency electromagnetic waves to heat things, and use the chip to control the on-off time of the main circuit to control the heating power. However, these operations are all done by manual selection, and the degree of automation is low. Troublesome operation, low work efficiency, time-consuming and labor-intensive
