Gas tunnel oven

Share to:

1)Material (appearance, inner throat, chain): All stainless steel, caching the pressure baked to the furnace for a long time to ensure that the internal and external plates are not deformed, improve corrosion resistance, chain plate delivery, large roller carbon steel chain plus gold envelope transmission, high temperature, wear resistance.

2)Inner: Adopting the vault design (this design has been applied for patent, patent number: ZL 2012 30159711.5), uniform thermal radiation, natural convection, no circular dead angle, get rid of conventional furnace circulating fan, uniform temperature, so that the bakery product is uniform To achieve the most perfect baking effect.

3)structure: Hotfire reflection design (this design has been applied for patent, patent number: ZL 2012 30159705X), prevents the furnace shift, deformed, increase the operating life of the stove, and ensure the product baking effect.

4)Ignition system:A: With an exclusive development of large mouth diameter 32mm straight-fired four-row fire hole seamless fire tube, strong fire, rapid temperature rise, take the second forced combustion method to ensure full combustion of fuel;

B: Exclusive customization high requirements igniter: 1, with the pre-sweeping function (before ignition, the fan is first predited to remove other gases in the fire, ensure the oxygen content in the air in the fire tube, improve the success rate of ignition ); 2, use a one-track ignition program, fundamentally prevents repeated ignition and eliminating safety hazards. Two points above, double insurance, and worry-free.

5)Control System:With Omron, Schneider, Siemens, Delta and other international cutting-edge electronic accessories brand, high quality use configuration, so that you should use your daily use. Intelligent control, the operating system is simple, and the alarm light and alarm are configured to prevent misuse. Anti-back fire safety control mode, automatic check of gas loss and fire failure alarm.

6)GAS combustion system: GAS force combustion system + automatic fuel-burning system to ensure gas fully combustion, automatically control CO2Safety value. Each combustion rod can automatically detect the burning state, so that you will freely inspect the trouble of test failure; if you reset it, you can use it to remove the fault, which is extremely convenient. Variety of gas variety, liquefied petroleum gas (LPG), natural gas (LNG), COAL GAS). The air supply pressure is as high as 3500Pa, the performance is stable, and the operation is reliable.

7)Insulation Materials: High-performance ceramic fiber blanket, aluminum silicate rock plate, the top plate of the furnace, the left and right side plate bottom plates, the thickness of the left and right panels is not less than 235 mm, the thermal insulation effect is good, during use, the outer surface temperature of the furnace is close to normal temperature, to ensure the production workshop The temperature is not affected by the equipment, ensuring the physical and mental health of employees, and improves production workshop.

8)Hot air circulation system: Increase the flow and heat exchange time of the furnace in the unit time, improve the heating speed of the baking product, achieving the purpose of environmental protection; can be opened or closed according to the process requirements of the baking product, or partially open, partially open , Can be flexibly applied according to the requirements of the barrier.

(Note: The length is determined according to the actual production needs and the size of the site)
