Abstract

The invention discloses an automatic control device of a steam generator, and relates to the technical field of control over the steam generators for food processing. The automatic control device comprises a micro processor, a wireless communication module, a PC machine, a PWM driving circuit, a chopper circuit, a heating sheet, a boiler, a relay, a water feeding pump, a pressure sensor, a temperature sensor, a water level sensor and a signal conditioning circuit. The control device disclosed by the invention collects temperature, water level and pressure signals of the boiler through the sensors and transmits the signals to the micro processor; the micro processor controls the PWM driving circuit and the chopper circuit to heat water in the boiler through the electric heating sheet; the micro processor controls the relay and the water feeding pump to supply water to the boiler, so as to realize automatic control over the steam generator; the control device is high in reaction speed; and by the adoption of two-stage control of the micro processor and the PC machine, the steam pressure can be stably controlled.

Description

technical field [0001] The invention relates to the technical field of steam generator control for food processing, in particular to an automatic control device for a steam generator. Background technique [0002] A steam generator refers to a mechanical device that uses heat energy (such as electric energy) from fuel or other energy sources to heat water into steam. Steam generators are mainly classified according to fuel, and can be divided into electric steam generators, fuel steam generators, and gas steam generators. generator etc. The existing steam generator uses electric heating plates to heat the water in the furnace to make it into the required steam, and the purpose of controlling the generated steam pressure is achieved by controlling the temperature. However, the slow response speed of the control device and the poor computing power of the MCU lead to extremely unstable steam pressure. Contents of the invention [0003] The present invention provides an auto...
