Food Gas Tunnel Furnace

A Food Gas Tunnel Furnace is a large-scale industrial continuous baking and heating equipment designed for modern food production lines. It uses pipeline natural gas or liquefied petroleum gas (LPG) as the energy source and continuously conveys materials into the tunnel-shaped baking chamber through a continuously running conveyor system.The equipment adopts a microcomputer intelligent control system to achieve precise segmented temperature adjustment. With uniform heat distribution and stable baking performance, it is especially suitable for modern food factories requiring high production capacity and continuous automated production.

Product Applications

This equipment is widely used for large-scale continuous baking of various food products, including:

1. Bakery Products

Bread, cakes, mooncakes, biscuits, toast, baguettes, and other baked goods.

2. Snack Foods

Roasted nuts, dried meat slices, dried fish, puffed foods, pizza, and other snack products.

3. Traditional Chinese Pastries

Sesame cakes, flatbreads, and various Chinese-style pastries.

Product Parameters

The following are parameters of standard models. Customized designs are available according to production capacity requirements.

Product Features

1. High Efficiency and Energy Saving

The furnace adopts an advanced direct-fired combustion system or hot air circulation combustion system, providing high thermal efficiency and significantly reducing energy costs compared with traditional electric ovens.

2. Independent Temperature Control

The tunnel furnace is divided into multiple temperature zones. The upper and lower heating systems can be controlled independently to meet the baking requirements of different food products at various stages.

3. Large Production Capacity

With continuous feeding and discharging on the production line and variable frequency conveyor speed control, the production capacity is several times or even dozens of times higher than that of conventional deck ovens.

4. Safe and Intelligent Operation

Equipped with a fully automatic ignition system, flame failure protection, over-temperature alarm, and gas leakage detection system to ensure safe production.

FAQ 

Q1: Compared with an electric heating tunnel furnace, which one is more cost-effective?

A: Under normal circumstances, the operating cost of a gas tunnel furnace is 30%~40% lower than that of an electric tunnel furnace. However, the initial equipment investment and gas pipeline installation costs are higher. It is more suitable for large-scale and long-term production.

Q2: How should the length and width of the furnace be selected?

A: The selection depends on the product type, individual product weight, and expected hourly production capacity. We will calculate the required baking area according to the production output and recommend a suitable furnace length and width.

Q3: If a sudden power failure occurs during baking, will the food inside the furnace be burnt?

A: No. The equipment is equipped with a manual crank handle or emergency backup power interface. In case of power failure, the conveyor belt can be operated manually or through backup power to safely move the products out of the furnace.

Q4: Is the safety level of a gas tunnel furnace high?

A: Yes. The equipment is equipped with imported Japanese/European gas valve assemblies as standard, featuring multiple safety protection mechanisms, including ignition failure lockout, automatic gas shut-off after accidental flameout, forced exhaust protection, and other explosion-proof safety functions.

Q5: What is the difference between a mesh belt and a chain plate conveyor? Which one should be selected?

A: The mesh belt provides excellent air permeability and faster heat penetration, making it suitable for lightweight foods such as biscuits and bread placed directly on the conveyor.

The chain plate conveyor has higher load capacity and better flatness, making it suitable for products baked with molds, such as cakes and mooncakes.
