FOOD EXTRUSION PROCESSING: AN OVERVIEW

FOOD EXTRUSION PROCESSING: AN OVERVIEWByBon-Jae Gu, School of Food Science, Washington State University. Ryan J. Kowalski, School of Food Science, Washington State University. Girish M. Ganjyal, School of Food Science, Washington State UniversityFS264 EFS264E | Page 1 | EXTRUSION Processing: An OverviewSummaryExtrusion processing is a commonly used processing technology in the food industry with a wide number of applications. It is a processing system that utilizes a single screw or a set of screws to force food materials through a small opening.

The most common extruder types used in food processing are single-screw extruders and twin-screw extruders. A single-screw extruder consists of only one screw housed in the barrel that often has a fluted or grooved design. Additionally, the screw in a single-screw extruder is usually designed with a decreasing pitch to create compression.

With a single screw extruder the hopper is filled and the screw takes in the material at the rate it wants. Such a scheme, called flood feeding, is often not possible with twin screw machines. This is because the very positive feeding characteristics of twin screw machines may result in very high forces being generated.

Single Screw Extruder (courtesy of Dr. Harold Giles) Post Extrusion Equipment Once the extrudate leaves the die it can either be set to the shape to be pro-duced or have its shape altered and then set to shape. The equipment that does this is called the ‘post extrusion equipment’ or the ‘haul off’ and in terms

The single screw extruder is basically a volumetric pump. It is not a positive displacement device. Variations in feeding result in variations in output. Solid conveying, melting, pumping and mixing occur simultaneously and are inter-dependent.

Screw The basic functions of the screw are: (1) To transport the polymer from the feed hopper to the extruder outlet. (2) To bring about the melting of the polymer. (3) To carry out any mixing required during the process. (4) To generate a stable and homogeneous supply of polymer melt.
