Gas-fired continuous tunnel furnace is baking devices used for food production such as moon-cakes, cakes, hamburgers, and toasts. The length of the continuous tunnel furnace can be customized according to the customer's production capacity. lt incorporates an advanced safety system with features such as intelligent ignition, automatic exhaust extraction of residual waste gas, flame failure detection, and pressure monitoring. KC-SMART is a distinguished China continuous tunnel furnace supplier, known for its advanced production capabilities and commitment to quality.

Zero-pressure Proportional Gas-fired Tunnel Furnace: 

Based on the centralized air supply tunnel oven, it adds components such as a proportional motor and an air-fuel valve. The gas passes through he air-fuel valve, achieving a pressure equal to the normal atmospheric pressure before combustion. After the air and gas are fully mixed, they are burned in the furnace through the burner tube. It boasts stable pressure, sufficient gas combustion, stable flames, low energy consumption, low failure ate, precise temperature control, and multi-stage adjustable fire in the rear area, ensuring uniform product color.

As a trusted manufacturer and customized continuous tunnel furnace supplier, we focus on precision and efficiency in every product.

1. Adopting intelligent and PID control, as well as combustion proportion control,the zero-pressure proportional tunnel furnace achieves precise temperature control.

2. The furnace chamber utilizes aluminum plate to radiate heat energy, resulting in higher thermal efficiency and a reflectivity of 50%-70%. This saves energy, stabilizes the temperature inside the furnace, and reduces heat transfer to the exterior. It also avoids food contamination caused by paint peeling on the furnace chamber.

3. The conveyor chain and guide rail are made of manganese steel, which is wear-resistant at high temperatures and extends the service life by 30%-50%.

4. High-quality insulation cotton is used to increase thickness, reducing heat loss and external heat transfer, thereby saving energy consumption.

5. The rear section of the combustion fire tube uses adjustable multi-stage fire, allowing for adjustment of firepower size, which facilitates product quality adjustment.

6. The last two zones are equipped with hot air circulation, resulting in a more uniform color of the baked products.

7. The working principle of the zero-pressure proportional tunnel furnace is to fully mix air and natural go through a proportional motor and zero-pressure valve before combustion, ensuring complete gas combustion and thus saving energy consumption.

Q: What are the key differences between the Centralized Air Supply Gas-Fired Tunnel Oven and the Zero-Pressure Proportional Tunnel Oven?

A: The main difference lies in their temperature control systems. While both ovens offer precise temperature control and stable flame combustion with a hot air circulation system for even product coloration, the Zero-Pressure Proportional Tunnel Oven features an additional proportional motor and an air-fuel ratio valve, enabling even more precise temperature adjustments.

Q: How does the hot air circulation system ensure even baking in your continuous tunnel furnace?

A: The hot air circulation system within our continuous tunnel furnace ensures that heated air is evenly distributed throughout the oven chamber. This not only promotes uniform baking but also helps achieve consistent product coloration and texture. The continuous circulation of hot air minimizes temperature gradients, resulting in superior baking quality.

Q: Are your continuous tunnel furnaces energy-efficient?

A: Yes, our tunnel ovens are designed with energy efficiency in mind. The stable flame combustion and precise temperature control minimize energy waste. Additionally, the efficient hot air circulation system contributes to faster heat transfer, further reducing energy consumption.

Q: Can your tunnel ovens handle large-scale production requirements?

A: Absolutely. Our continuous tunnel furnaces are built to withstand heavy-duty use in commercial and industrial settings. Their continuous conveyor belt design allows for seamless product flow, making them ideal for high-volume production lines.

Q: What safety features do your continuous tunnel furnace incorporate?

A: Our continuous tunnel furnaces come equipped with multiple safety features, including but not limited to overheat protection, flame failure detection, and emergency stop buttons. These features ensure the safe operation of the oven and protect against potential hazards, such as fire or excessive heat build-up.
