As one of the manufacturers of tunnel ovens, SAIMAI's tunnel ovens range in working widths from 1050mm to 3300mm and can be configured for virtually any type of product. Our experience in tunnel oven technology allows us to design and commission the optimum baking solution for our clients. We offer heating systems that include, convection (indirect-heated), direct gas-fired and hybrid methods.

Saimai's new type tunnel oven is a direct heated oven for industrial bakeries. The required heat is created directly in the baking tunnel by means of modulating ribbon gas burners. The construction of the baking tunnel, divided into modules, guarantees an even heat transfer to the product.

Burners will have their service side on the right or left hand side of the oven, when viewed in baking direction.

Ignition System

It is automatically controlled by the burning program controller, and each burning pipe can be selected and turned on/off from the touch screen, so as to achieve precise control of the burning pipe on/off in each zone. Flame detection ensures gas is cut off when there is no flame in the combustion system. Each temperature zone is equipped with 1 set of gas treatment system and 1 set of air supply system. The gas after treated is in a zero pressure state; the air supply system provides a controlled air flow, and the air generates negative pressure when it flows through venturi. The gas is supplied in proportion to the air under the adsorption of negative pressure (i.e, the Venturi effect), and then they are ignited by an electric spark through the ignitor, thereby realizing combustion.

Gas Supply and Control System;

1. Adopted with the world leading brand DUNGS of Germany for safe and clean gas combustion, It develop and manufacture innovative system solutions for the gas industry components.
2. Each zone is equipped with an independent gas supply system to ensure that each zone is independently controlled.
3. After the gas is filtered by a filter, it passes through the gas regulator to reduce the pressure and meet the requirement of actual production.
4. The dual electromagnetic slow-opening valves is equipped to control the ON and OFF of gas supply.
5. The slow-opening valve can effectively prevent the sudden connection of the gas from impacting the gas pipeline, and a pressure protection switch is equipped for safety protection.

Our head quarter Saimai Company has been founded in China since 1976. We focused on rubber, painting, and coating for ships and bridges.
