Spiral Oven


Cooking, heating, browning: The spiral oven from JBT ALCO slowly and gently runs products through the cooking process by means of a spiral conveyor belt that can be extended if required. That way, large quantities of your product will be cooked, roasted, browned, or just steam-cooked very evenly in the spiral oven with circulating air and/or steam. The smart spiral system makes optimum use of the available space, so that maximum production capacity is achieved in the smallest possible space. At the same time, the distance between the individual levels and therefore the possible product height can be flexibly varied by selecting the number of levels. That way, even larger products such as whole chicken, burgers, or lasagna get their appetizing brownness and succulent consistency.


Our spiral oven heats, cooks, and browns products through circulating air and/or steam. Adjust the spiral belt guide individually to product quantity and size.

Perfectly suitable for:
meat loaf, whole chickens, burgers, nuggets, bacon, lasagna, pretzels
