Method and apparatus for processing foods into tubular shape

摘要

A method and an apparatus for processing food into a tubular shape is provided in which a die for processing the food includes a guide plate having a material outlet and a cylindrical feed pin having a water outlet at its center co-axially housed in the material outlet. The guide plate and feed pin cooperatively define a ring-like opening. Food material is extruded out of the ring-like opening in a tubular shape. Simultaneously, hot water is expelled out of the water outlet of the feed pin, flows into and fills a hollow inside the tubular food material. The hot water in the hollow prevents the wall of the tubular food material from collapsing and also accelerates coagulation of the food material. Food material is thus continuously processed into a tubular shape. An extruding die for performing the described method is also provided. $$
