CYCLOTHERMIC TUNNEL OVEN
The cyclothermic TUNNEL oven is the most traditional tunnel oven and one of the most used in the world
Inside a room of combustion in steel and refractory combustion develops thanks to a modulating burner that can work gas or diesel. The combustion fumes are conveyed thanks to a fan with two upper tube bundles and lower in order to heat them and cook the product by radiation. the high thermal mass, flexibility of use of different fuels and independent upper and lower heat regulation, combined with humidity control accurate, has made this technology very popular for dry biscuits, shortbread, bread, cakes, cakes and other products. There reduced maintenance and ease of use make it suitable for many situations.
CONVECTION TUNNEL OVEN
The direct or indirect convection TUNNEL oven transmits heat through a flow of hot air that is generated in the furnace top of the area.
This flow of hot air is generated by a modulating gas burner (in the case of the direct convection) or from a heat exchanger where the indirect combustion and heating process takes place cooking air. The heated air is conveyed into the cooking chamber through ducts appropriately shaped and blown onto the product. The air is recovered through lateral ducts and then partially expelled and re-integrated with fresh air. Convection cooking favors fatty doughs such as shortbread, extruded products and pastry and is suitable for obtaining low humidity and uniform color on production.
ELECTRIC TUNNEL OVEN
The electric TUNNEL oven is the most environmentally friendly as it does not use fossil fuels
and is the absolute oven with the best temperature control and with the least maintenance required. Several toroidal resistors are installed transversely to the direction of travel of the oven both in the upper and lower part of the conveyor to allow you to cook flexibly. a PLC control system manages the modulation of the cooking zones while suction is guaranteed by a central duct that guarantees constant suction with the least possible turbulence.
DIRECT GAS TUNNEL OVEN
The direct flame TUNNEL oven is especially used in the production of crackers and laminates due to its high transfer of heat mainly by radiation.
Numerous sword burners are installed transversely to the direction of travel
of the tunnel oven both in the upper and in the lower part of the conveyor to allow cooking in a manner flexible according to needs. about 15% of these burners are tri-flame with the possibility of adjusting on the left, in the center and on the right the power and make the cooking of the product uniform over the entire width of the band. Every burner is equipped with a double gas safety valve and a dedicated flame control and can be used natural gas or LPG indiscriminately thanks to a simple recalibration of the mixer of each burner while aspiration it is guaranteed by a central duct that guarantees constant suction with the least possible turbulence.
CUSTOMIZED SOLUTION OF TUNNEL OVENS
The construction of special high temperature TUNNEL OVENS
for the cooking of nachos, tortillas and wraps also multi-level, tunnel ovens for the grilling and cooking of vegetables, and more, are part of the product portfolio that Laser can offer.
Laser is able to produce lines up to 4 meters wide for important productions
To satisfy all types of customers, Laser has adapted to different production widths. The sturdiness of the structure, combined with the care of the materials, offer the tranquility of an absolute quality product even for important productions.
MANY options and customizations can be integrated into the Laser TUNNEL ovens to facilitate cooking as well as maintenance and cleaning
Cleaning systems for belts or nets, tunnel oven unloading conveyors, automation complete with cooking parameters with pressure sensors are some of the options that you can to install. it is also possible to integrate the oven with steam injection systems, glazing via infrared burners, internal turbulence generation systems, and special designs suitable for particular products can be adopted to further customize the cooking of more complex products.
The tranquility of assembly of modular ovens
The assembly phase cannot be neglected
Laser produces modular ovens that can be transported in blocks that can be perfectly assembled at the customer’s company with greater ease, precision and time optimization.
Numerous conveyors can be used in laser TUNNEL ovens to support the cooking of the most demanding products.
From IPCO solid or perforated steel bands, to Z47 or CB3 or CB5 type nets, up to dedicated transport for trays or belts in plastic material it is possible to design the correct oven transport system for each product. automatic systems
tensioning and centering systems with intelligent operation, UPS systems for emergency product unloading,
cleaning brushes or scraper assemblies ensure that the useful life of the conveyor is maximized and costs are reduced maintenance and cleaning.
