(1) electric oven, electric toaster type oven heat source type of general term. General electric oven structure is relatively simple, composed of shell components, electric heating wire (or infrared ray tube), heat control switch, oven temperature indicators. Advanced electric oven last year under the fire, spray steam, timer, alarm and other special features adjusted. Its working principle is mainly through infrared heat radiation power conversion, furnace hot air convection heat transfer and thermal conductivity of the metal plate inside the furnace, such a mature product color. The toaster is very easy to use, adaptable, emissions and the use of toxic substances, the product is clean and hygienic.

(2) gas coke oven gas oven, gas oven heat source, usually single-story structure, the bottom and both sides of the combustion baking device, automatic ignition and temperature control function, the temperature as high as 300 ° C. It is through the combustion of gas radiant heat, hot air convection oven oven metal conduction and heat conduction, so that a mature product color and maturity. Gas oven preheating faster, easier to control the temperature, low production costs, but this oven clean and healthy work more difficult.
