The Bread Baking Tunnel Oven is an industrial continuous automatic baking equipment specially designed for large-scale and standardized production of Nang bread. It overcomes the limitations of traditional handmade Nang pits, such as low production capacity and high energy consumption. Through a conveyor system, Nang dough pieces move continuously through a long heating chamber, enabling large-volume, uninterrupted, and automated baking production.

Application

Industrialized Professional Nang Bread Factories

Used for large-scale centralized production of various Xinjiang-style Nang breads, such as oil Nang, meat Nang, sesame Nang, and Wo Wo Nang, followed by nationwide distribution.

Central Kitchens and Large Food Processing Plants

Used for producing frozen and cold-chain Nang products, as well as pre-made bakery products supplied to restaurant chains, supermarkets, and retail channels.

Food Export Enterprises

Meets the requirements of international food transportation, including standardized production, stable quality, and extended shelf life for long-distance export.

Standards

Food Machinery Safety and Hygiene Standards

The equipment must comply with national food machinery safety and hygiene standards, such as:

GB 16798-1997 — Safety and Hygiene Requirements for Food Machinery

All parts inside the oven that come into contact with food must be made of food-grade stainless steel, such as SUS304 stainless steel.

Electrical and Gas Safety Standards

The complete machine must comply with electrical safety standards such as:

GB 4706.1

For gas-heated models, strict compliance with gas pipeline safety and explosion-proof requirements is required, including safety features such as explosion-proof vents, ignition safety interlocks, and flame protection systems.

Environmental Protection and Energy Consumption Standards

The equipment must comply with national and local industrial furnace emission standards. Exhaust emissions and noise levels must meet environmental protection requirements.

Features

Highly Simulates Traditional Nang Pit Heating Conditions

The equipment adopts a multi-zone independent temperature control system, usually equipped with quartz infrared heating, hot air circulation, or specially designed refractory panels. It accurately reproduces the traditional Nang pit heating environment, including upper and lower heating effects, ensuring Nang bread with a crispy exterior, soft interior, and uniform coloring.

Efficient Continuous Automated Production

The entire process, including feeding, baking, and unloading, is fully automated. Conveyor speed and temperature are controlled through PLC intelligent variable-frequency control, allowing seamless integration with upstream equipment such as dough pressing machines and pattern stamping machines.

Energy Saving, Environmental Protection, and Precise Temperature Control

Compared with traditional coal-fired or charcoal-fired Nang pits, the tunnel oven provides lower carbon emissions and improved environmental performance. The high-density insulation layer reduces heat loss and can save approximately 20%–30% energy compared with conventional ovens.

Comprehensive Safety Protection

The equipment is equipped with multiple intelligent safety protection systems, including:

Over-temperature alarm

Gas pressure low-pressure protection

Flame failure protection

Other automatic safety warning systems
