Barrel & Screw For Hot Melt Extrusion Process For Pharmaceutical Drug Formulation

Barrel & Screw Manufacturing Material For Food and Pharmaceutical Extruder

1 . Description

Since the food extruder and the pharmaceutical extruder are both powdery solid materials or granular solid materials to be fed, compared with the extrusion of ordinary polymer materials, they bear more severe shear wear and matching wear; and because these materials often still contain a certain amount of water or even a certain amount of salt, the barrel and screw are in alkaline corrosion conditions. Therefore, the barrel and screw of food extruder and pharmaceutical extruder need to be resistant to both wear and corrosion specially. Martensitic stainless steel with high corrosion resistance and high hardness has become our first choice for manufacturing the food barrel and screw.

 

The hardness of the 440C series stainless steel after quenching can reach HRC58~62, and it has excellent wear and corrosion resistance. It can be suitable for manufacturing that needs to withstand high wear resistance, high load, high torque, and under the action of acid and salt corrosive media, can be made the barrel, screw and die for the food extruder.

3 . Comparsion of the output (LDPE)

Barrel Screw For Hot Melt Extrusion Process For Pharmaceutical Drug Formulation 0

Pressure is generated if resin passes over the barrier, forcing any air in the melted resin back to the feed side and effectively preventing the intrusion of air bubbles on the sub flight side. This is highly effective with resins that generate bubbles such as PS, PA, PET and EVOH.

Bimetallic Treatment of Screw

The bimetallic screw for extruder twin screw is a kind of screw spray welding a 2~3mm-thick alloy coat on the screw flight of output area for the screw . The Bimetallic treatment has excellent corrosion resistance, abrasion resistance and high working temperature. And its useful service life is greatly improved contrast to the common nitrided screw.
