Abstract
In cooler used for coating a product such as food with a uniform layer of a liquid coating material, the mass of the product is measured either in the cooling chamber or just before it is introduced into the cooling chamber; the mass of a liquid cryogen which will suffice, when introduced into the cooling chamber and into contact with the product, to reduce the temperature of the mass of product to a first predetermined temperature below the melting point temperature of the coating material is calculated; the introduction of the calculated mass of liquid cryogen into the cooling chamber is controlled and the product is thereby cooled to the first predetermined temperature prior to application of a predetermined mass of coating material onto the cooled product to provide a coating thereon.
