ABSTRACT:
An extruder for food, having; a rotary cylinder fitted to a tip of an extrusion nozzle for extruding a food material; at least one feed opening formed in the outer periphery of the rotary cylinder, from which a different food material is fed; a stationary cylinder so fitted as to cover the feed opening in slidable contact with the outer periphery of the rotary cylinder, and having a circular space formed around the corresponding outer periphery of the rotary cylinder; and a feed pipe from which the different food material is fed into the circular space of the stationary cylinder. This extruder enables application of a variety of patterns of a spiral, wavy or like form, with use of such a simple structure that the rotary cylinder and the stationary cylinder are fitted to the tip of a nozzle. Due to the simplicity in the structure, it is also possible to perform with ease maintenance such as cleaning.
