Our spiral oven serves for cooking and/or browning your products with steam, hot circulating air, or both. Its spiral belt guide allows plenty of room in our oven for products, which are cooked in a gentle way. Authentic, unusually fast smoking is also possible through an external smoking system.

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. Several successively activated spirals allow for cooking over different climate zones. In addition, you can set the gap between the individual spiral levels exactly and smoke your product through an external smoking system with an individual intensity and color. That way, even larger products like whole chicken, burgers, or lasagna get their appetizing brownness and succulent consistency.

Perfectly suitable for meatloaf, whole chicken, burgers, nuggets, bacon, lasagna, pretzels
