The tunnel oven is one of our industrial & commercial bakery baking oven. We can customized according your capacity.

Indirect heated convection oven:

The burner heats the combustion chamber and the heat exchange, then the air which will be blown into the bake chamber is heated through the heat exchanger.


Direct fired oven:

Direct fired oven, use the burner tubing heating principle, effective to ensure evenly baking, uniform color, use negative pressure combustion principle, the safety of the oven operation is ensured.

1. The usage of the tunnel oven:

Suitable for loaf bread, buns, baguette, croissant, cakes, pita bread, Arabic bread, bagel, tortilla etc.

2. The advantage of proportion of zero-pressure gas-fired tunnel oven:

1) Insulation System:

A: Using rock wool insulation hybrid cotton,take access method for modular,more full of cotton insulation insulation properties, device power consumption to a minimum.

B: The inner wall of the oven used in all high reflection efficiency 1.5mm thick and 304 stainless steel bore, ensure the furnace during baking heat loss to a minimum.

2) Drive section:

A: The transport conveyor is the chain plate form, it use Hangzhou Donghua chain belt(European technology, customized professional manufacturers),advantages of low noise, wear-resistant high temperature of 500 degrees, chain material collected 40Cr alloy materials, after tested, ultimate tensile load reaches 100KN longer life, better stability, give customers more peace of mind.

B: Chain plate with hot rolled plate bending from 3.0, surface appearance, high strength, flexural resistance, proper storage of heat, stable transfer amount fiery end, the furnace temperature equilibrium. Four bolt connection.

C: SEW reducer and matching motor powered, frequency stepless speed can be precisely controlled by the baking time, good acoustics, high stability.

D: Conveyor using 65Mn spring tension way, the flexibility to automatically adjust the tightness of the conveyor belt, the chain operated more in line with the requirements of mechanics, running more smoothly.

3) Exhaust systems:

A: According to the arrangement of the baking process food inflation hair, stereotypes dehydration, color three stages, exhaust pipe arranged in three stages.

B: Exhaust hood using natural air ejector exhaust hood design, ensure reasonable nature row tide, using exhaust hood exhaust pipe design, not directly connected to the furnace smoke pipe tobacco pipe, but connected to the exhaust hood, around of exhaust hood may enter natural air. Because the furnace temperature and altitude smoke tube forming hot outside temperature difference stress, continuous upward flow of hot air, exhaust hood external natural cold air into supplemented by the exhaust hood, so that the smoke pipe gas flow kinetic energy increases, exhaust more smoothly reasonable, the real heat loss without affecting the premise of rational water vapor discharge, excess water vapor in the furnace if it can not reasonably discharge but will reduce the oven temperature to produce steam emission beneficial during baking products, avoid dripping water vapor to the product, the impact of product shelf life.
