TUNNEL OVEN

CONVECTION

Indirect forced air convection tunnel oven is suitable for baking of products ranging from soft dough products through hard/sweet to enzyme type cracker and combined with sections of the multi-burner system to form a hybrid solution for snack type products.

Tunnel oven consist of assembled modular structure supported by steel frame fixed to the floor. As a consequence of the heating, the baking chambers have the possibility to dilate, thanks to a specially designed “sliding” system.

Chambers and the combustion groups are constructed from materials suitable for operation at high temperatures.

Thermal insulation of rock wool or ceramic fibers is enclosed by protection panels and stainless steel covers.

Convection oven indirectly applies the temperature, obtained into the combustion chamber via a burner and via a stainless steel fan for air circulation. This heat is separated by a shutter into top and bottom pressure chambers. Each one of the pressure chambers can be independently controlled to maximize the energy efficient application to the product.

Presence of a heat exchanger coupled with the re-circulation of air from the baking chamber via the combustion chamber, allows rapid response to temperature fluctuations.
Idle head includes a system of pneumatic tensioning.

Towing group, positioned on the output head, is composed of a motor controlled by inverter and a towing device that can be manually activated in case of emergency.
Whole system is controlled by an electrical panel placed near the oven.

CYCLOTHERMIC

Cyclotherm tunnel oven is suitable for baking of products ranging from cupcake, Swiss roll and other sponge products, extruded, wire cut and rotary moulded soft dough products through to hard/sweet and bread.

Oven consist of assembled modular structure supported by steel frame fixed to the floor. As a consequence of the heating, the baking chambers have the possibility to dilate, thanks to a specially designed “sliding” system. Chambers and the combustion groups are constructed from materials suitable for operation at high temperatures.

Thermal insulation of rock wool or ceramic fibers is enclosed by protection panels and stainless steel covers.

Tunnel oven baking chamber is constructed to include segregated channels through which the heat from the power module is transferred to the radiators placed above and below the oven conveyor. A sufficient number of channels is provided to supply a balanced thermal load. Cyclotherm oven applies the temperature, obtained into the combustion chamber via a stainless steel burner and via a re-circulation fan to the top and bottom radiators (sheaf of tubes). Heat transfer to the two radiators is independently controlled.

Idle head includes a system of pneumatic tensioning.
Towing group, positioned on the output head, is composed of a motor controlled by inverter and a towing device that can be manually activated in case of emergency.

Whole system is controlled by an electrical panel placed near the oven.

DIRECT GAS

Direct gas fired tunnel oven is suitable for baking of products ranging from soft dough products through hard/sweet to cracker, soda cracker and baked (not fried) snack type products. The combination with cyclotherm or convection sections can be used as hybrid solutions for baked snack type products.

Tunnel oven consist of assembled modular structure supported by steel frame fixed to the floor. As a consequence of the heating, the baking chambers have the possibility to dilate, thanks to a specially designed “sliding” system.

Chambers and the combustion groups are constructed from materials suitable for operation at high temperatures.
Thermal insulation of rock wool or ceramic fibers is enclosed by protection panels and stainless steel covers.

Heat transmission inside the oven is achieved thanks to the combustion generated by the burners positioned on the top and the bottom of the baking chamber.

Multi-burner gas oven is supplied with combined system with controlled ignition, self-checking spark and flame, burner safety system to each single burner, conforming with worldwide safety regulations.

Idle head includes a system of pneumatic tensioning.
Towing group, positioned on the output head, is composed of a motor controlled by inverter and a towing device that can be manually activated in case of emergency.

Whole system is controlled by an electrical panel placed near the oven.

HYBRID

The Hybrid Oven system is used to match two or more different heating systems.

The baking flexibility is highlighted in the thermal settings, with the possibility of differentiating the temperature of each zone, by moving air inside the baking chamber and managing the vapor suction system in each individual zone.

The following combinations of tunnel oven can be obtained:
– Direct flame + cyclothermal
– Direct flame + Cyclothermal + Convection
– Cyclothermal + Convection

Between a heating circuit and the next one, a protective shutter is placed in order to avoid air movements and temperature interferences.

HIGH TEMPERATURE

This special tunnel oven has been designed and realized for the products as like pizza, pita, piadina and similar that require high temperature and brief baking time.

Oven consist of assembled modular structure supported by steel frame fixed to the floor. As a consequence of the heating, the baking chambers have the possibility to dilate, thanks to a specially designed “sliding” system.

Chambers and the combustion groups are constructed from materials suitable for operation at high temperatures.

Thermal insulation of rock wool or ceramic fibers is enclosed by protection panels and stainless steel covers.

Heat transmission inside the oven is achieved thanks to the combustion generated by the radiant burners positioned on the top and the bottom of the baking chamber.

The heat transmitted to the product follows two principles:
– Irradiation: due to the temperature difference between the surface of the panel and the product;
– Convection: by the heated air that has been in contact with the flame.

Each baking zone is equipped with independent temperature control for both groups of burners positioned on the top side of the baking chamber and on the bottom.

Vapors and fumes created in the chamber, are extracted by a channel positioned longitudinally of the oven, connected to a chimney and equipped with suction fan and shutters.
Product transport is provided with stone conveyor chain.
Idle head includes a system of pneumatic tensioning.
Towing group, positioned on the output head, is composed of a motor controlled by inverter and a towing device that can be manually activated in case of emergency. Whole system is controlled by an electrical panel placed near the oven.
