What do you mean by extrusion technology?

Extrusion technology is gaining increasing popularity in the global agro-food processing industry, which employs mixing, forming, texturing and cooking to develop a novel food product. Extrusion cooking is a high-temperature short-time (HTST) process which inactivates enzymes and reduces microbial contamination.

How does extrusion technology work?

Extrusion is used in food processing, forcing soft mixed ingredients through an opening in a perforated plate or die designed to produce the required shape. The extruded food is then cut to a specific size by blades. The machine which forces the mix through the die is an extruder, and the mix is known as the extrudate.

What is an example of extrusion?

Everyday examples of extrusion can be seen when toothpaste is squeezed out of a tube, icing is pushed out of an icing bag and “Playdo” shapes are made. Extrusion moulding of plastics is used to make any long shape that has a constant cross section. Perhaps most common plastic extruded is PVC.

What is extrusion food processing?

Summary. Extrusion 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.

What are the advantages of extrusion?

Advantages of extrusion

  • Low cost per part.
  • Flexibility of operation.
  • In hot extrusion, post execution alterations are easy because product is still in heated condition.
  • Continuous operation.
  • High production volumes.
  • Many types of raw materials can be used.
  • Good mixing (Compounding)
  • Surface finish obtained is good.

What is the principle of extrusion?

Extrusion is a metal forming process in which metal or work piece is forced to flow through a die to reduce its cross section or convert it into desire shape. This process is extensively used in pipes and steel rods manufacturing. The force used to extrude the work piece is compressive in nature.

What is pipe extrusion process?

A pipe extrusion line consists of a number of pieces of equipment. An extruder converts the polyethylene raw material to a continuous tubular melt by extrusion through an annular die. The molten pipe then proceeds through a sizing or calibration device (which fixes its dimensions) to a cooling trough.

What are the advantages and disadvantages of extrusion?

While the extrusion molding process offers advantages to manufacturers, it has disadvantages as well.

  • Advantage – Low Cost. Extrusion molding has a low cost relative to other molding processes.
  • Advantage – Flexibility.
  • Advantage – Post- Extrusion Alterations.
  • Disadvantage – Size Variances.
  • Disadvantage – Product Limitations.
