The main differences between a tunnel furnace and an oven come down to physical structure, baking method, and production efficiency.
Physical structure
An oven is usually an open square or rectangular box. Its structure is simple, which makes operation and cleaning easier. A tunnel furnace is much larger. It includes an automatic feeding system that moves products into the chamber, along with other sections.
Baking method
An oven can handle baking, roasting, smoking, and similar operations. It offers high flexibility. A tunnel furnace is mainly used for baking food in large batches. It provides an efficient baking method and greater capacity.
Production efficiency
An oven is easy to operate, but it cannot meet large-scale production needs. A tunnel furnace suits large-scale, high-temperature baking. Its baking efficiency is far higher than an oven, and it can produce food of more consistent quality.
Hansheng Automation can machine custom conveyor components, drive parts, and heat-resistant fixtures for tunnel furnaces from customer drawings, in single pieces or small batches.
Beyond the applications above, our precision component customization covers more than one industry. We machine yacht precision components, RC car precision components, food machinery parts, tobacco packaging machinery parts, filling machinery parts, printing machinery parts, and medical device parts. Hansheng Automation works from customer drawings and delivers one-off or batch parts to the required material, tolerance, and surface finish. Our scope is precision components, not complete machines.
