Tunnel furnace electrical control system and method thereof

Abstract

The invention discloses a tunnel furnace electrical control system and a method thereof. The tunnel furnace electrical control system comprises a programmable controller and a transmission chain, wherein the transmission chain is driven by a driving motor to rotate, the programmable controller is electrically connected with the driving motor, a tunnel furnace is provided with a plurality of heating areas, each heating area is equipped with an independent fire tube heater, a cold end temperature compensation device, a temperature collector, a strong exhaust fan and a blower. The temperature collectors collect the current area temperature and feedback the current area temperature to the programmable controller; and the programmable controller outputs control signals to the fire tube heaters, the cold end temperature compensation devices, the strong exhaust fans and the blowers correspondingly, and controls the operation of the fire tube heaters, the strong exhaust fans, the cold end temperature compensation devices or the blowers. According to the tunnel furnace electrical control system and the method thereof, most of the interference and uncertainty factors can be overcome, and satisfactory accuracy and temperature are achieved.

Description

technical field [0001] The invention relates to the field of food processing equipment, in particular to an electrical control system for a tunnel furnace and a method thereof. Background technique [0002] Bread is generally a food made by grinding and heating five grains (usually wheat). With wheat flour as the main raw material, yeast, eggs, oil, sugar, salt, etc. as auxiliary materials, the baked food is made into dough by adding water, and processed through division, forming, proofing, baking, cooling and other processes. Generally, baking furnaces or tunnel furnaces are used, which are widely used due to the advantages of simple one-time molding operation. [0003] The heating components of the existing bread-baking tunnel ovens generally only use a single control method, but unified electric heating production is not suitable for all bread-making environments, resulting in unsatisfactory bread produced, and the conveyor belt chain in the tunnel oven is continuously ...

AI Technical Summary

Problems solved by technology

[0003] The heating components of the existing bread-baking tunnel ovens generally only use a single control method, but unified electric heating production is not suitable for all bread-making environments, resulting in unsatisfactory bread produced, and the conveyor belt chain in the tunnel oven is continuously In a high temperature state, the conveyor belt is easily damaged, making the service life of the tunnel furnace not long

If the residual gas in the previous tunnel furnace was not cleaned up in time, it is easy to cause an explosion if the production starts directly
