Single and twin screw extrusion is
used to process a varity of foods for human and pet consumption. Common
extruded foods include sausages, processed meats, dough, pasta, cereals,
snack foods, candy and animal feeds. JINYI manufactures monolithic
Stainless steel screw barrel sets for ultra pure applications.
Food process extruders for the
most part are single or twin screw design. There are various different
equipment types and many custom designed machines. Each machine is
configured for the specific application. General types include single
screw cooking, continuous pasta, dough, pelletizing extruders and co and
counter rotating twin screw extruders. It is imperative to use
acceptable alloys for the construction of the component surfaces that
come into contact with the food materials being processed. The barrel ID
surface must be compatible with the feed screw and the material being
worked. Of equal importance is resistance to abrasion and corrosion
wear. Pitting of the ID surface can cause a stagnation of the material
being processed leading to degradation and contamination. Significant
abrasion wear can result in foreign elements being present in the end
product.
Our food processing screws barrels are in various size with high durability and corrosion resistance.
We use the supreme quality raw
material to manufacture food processing screw barrel. The accurate
dimensions given by our highly skilled professionals, the superior
finish make all our clients happy and satisfied with our delivered
products.
