A dielectric method of drying a hot plastic food extrudate comprises extruding the hot plastic food material from a food extruder, passing the extruded hot plastic food material while the material is still plastic to a dielectric heating apparatus which is in close proximity to the food extruder, and subjecting the hot plastic food material to dielectric heating.

A continuous process for producing pretzels is disclosed in which an essentially dry mixture containing flour, corn starch hydrolysates and salt is introduced into an extruder; water is injected into the extruder barrel to bring the water level of the mixture to between 19% and 25%; the material is extruded at non-cooking temperature to form a self-supporting ribbon of extrudate; the extrudate is sprayed with a caustic solution; and the sprayed extrudate is baked. The claimed process is adaptable to the continuous production of a filled pretzel product.
