Product Description

Screw Barrel for Food Processing and Extrusion

Single and twin screw extrusion is used to process a variety of foods for human and pet consumption. Common extruded foods include sausages, processed meats, dough, pasta, cereals, snack foods, candy and animal feeds. Ningbo 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.
