Method and apparatus for oil-free production of food products in a rotary impingement oven

摘要

A rotary air impingement oven enables volume production of oil-free food products including those from root crops such as potato chips. The over contains a cage-like drum with perforate, containing product therein, are exposed to temperature and velocity controlled impinging process vapor which is withdrawn continuously during drum rotation. The food products within the drum are urged by an internal baffle towards the drum discharge during rotation
