Tunnel bakery oven Meincke Turbu 4.0

convectionpizzabaked goods

Overview
The Meincke Turbu 4.0 is an indirect-fired convection tunnel oven designed for industrial baking of biscuits, cookies, cakes, pizzas, pies and similar products. It separates combustion gases from baking air via a heat exchanger to maintain consistent baking temperature and hygiene.

Key benefits

• Optimized heat transfer for uniform baking through a double-damper airflow control system.
• Modular 2 m prefabricated units enabling flexible line configuration and straightforward extensions.
• High repeatability of set-ups and recipe transfer based on long-term oven development experience.

Highlight features
Heating principle: Burner heats a combustion chamber; heat is transferred to a separate heat-exchanger room so combustion gases do not contact baking air. Heated air is circulated to the baking chamber to provide controlled convection heat.

Ventilation system: An adjustable damper and fan system distributes hot air to top and bottom ducts. Oven air is continuously exhausted, mixed with fresh air and returned to the heat exchanger; baking fumes are evacuated via a flue.

Using different types of heat: Primary heat transfer is by convection; conductive heat from the hot baking band and thermal radiation from plenums also contribute. Burner temperature, top/bottom air distribution and humidity profile are adjustable to adapt heat transfer to product requirements.
