Název projektu: Podpora společnosti J4 s.r.o. na zahraničních trzích

Registrační číslo projektu: CZ.01.2.111/0.0/0.0/16_047/0008908

Popis projektu: Projekt je realizován v rámci Operačního programu Podnikání a inovace pro konkurenceschopnost. Předmětem předkládaného projektu je zvýšení konkurenceschopnosti společnosti J4 s.r.o. na zahraničních trzích, a to pomocí podpory účasti firmy na 7 mezinárodních veletrzích v letech 2017 až 2019. Účast na vybraných veletrzích přispěje společnosti k novým zakázkám, zvýšení obratů a také k celkovému růstu společnosti. Projekt je spolufinancován Evropskou unií.

Cyclothermic tunnel ovens with a band width of 0,6 – 4m are the widest ranging type of tunnel ovens.

Cyclotherm tunnel ovens

They are intended for higher volumes of production and for baking all common and uncommon types of bakery products.

Configuration of baking oven

Baking cyclothermic ovens are especially designed to suit the requirements for the course of the temperature curve and in the way so that the technology requirements for the baking of the specific product should be met. By appropriate arrangement of heating zones and of position of the tower, it is possible to achieve as well as quite different temperature curves, all can be discussed with our specialists during the project of the line.

Ovens are generally equipped with steam zone, two helical bevel gear boxes for the band drive, wire mesh bend, burners Weishaupt and stainless steel sheeting. As an option we can equip the tunnel oven with duotherm, extended steam zone, forced exhaust of vapours and with many other accessories, that is shown in Accessories and additional executions of the ovens.

Axonometric profile of a single tower, cyclothermic baking band oven PPP with mechanical tensioning of the wire mesh band, with steam zone and band drive with two shaft mounted helical bevel gearboxes:
