    Overcooker product

    The Laitram Machinery CoolSteam® Technology uses a forced convection method. In this process, a low-temperature mixture of air and steam is constantly circulated inside the chamber, distributing heat efficiently and uniformly. Product is cooked, blanched or pasteurized consistently using less steam than traditional methods, and maintaining high quality products.

    Products cooked using the CoolSteam® Technology maintain a lower internal temperature, so the outside of the product does not become overcooked. As a result, more of the product’s natural moisture is retained and texture, taste and appearance are superior.
