Tunnel Oven Manufacturer

As a trusted tunnel oven manufacturer with over 40 years of industry expertise, Wenva Machine delivers advanced automated baking equipment designed for high-efficiency and consistent biscuit production. Our tunnel ovens are engineered with precision, incorporating insights from leading European and Japanese baking technologies, while adhering strictly to international quality standards.

Tunnel ovens are long, continuous baking systems designed for high-volume production of biscuits, cookies, crackers, and other baked goods. These ovens use either gas, electricity, or thermal oil as a heat source and are ideal for large-scale industrial food production due to their efficiency, reliability, and uniform heat distribution.

At Wenva Machine, we understand that the baking process is the heart of biscuit manufacturing. That’s why we’ve dedicated decades to innovating and refining our tunnel ovens to ensure perfect baking results in every batch.

How to Use a Tunnel Oven

Operating a tunnel oven is straightforward with Wenva’s user-centric design. Here's a general overview of how our tunnel ovens are used in biscuit production:

Preheat the Oven: Set the desired temperature zones using the touchscreen panel. The oven will gradually heat up to the required levels.

Conveying the Dough: Shaped biscuit dough is placed on the conveyor belt, which moves at a programmable speed through the oven.

Zone Baking: The tunnel oven is divided into multiple temperature-controlled zones. Each section bakes the product in a staged manner—starting from rising, to moisture evaporation, and finally to color development.

Discharge & Cooling: Baked biscuits exit the oven onto a cooling conveyor before packaging.

Each tunnel oven from Wenva is pre-programmed with baking profiles, allowing operators to easily switch between different recipes with minimal manual intervention.
