Brief Introduction
Food Extrusion is a form of extrusion used in food processing. It is a process by which a set of mixed ingredients are forced through an opening in a perforated plate or die with a design specific to the food, and is then cut to a specified size by blades. The machine which forces the mix through the die is an extruder, and the mix is known as the extrudate. The extruder consists of a large, rotating screw tightly fitting within a stationary barrel, at the end of which is the die.
Process
In the extrusion process, raw materials are first ground to the correct particle size, usually the consistency of coarse flour. The dry mix is passed through a pre-conditioner, in which other ingredients are added depending on the target product; these may be liquid sugar, fats, dyes, meats or water. Steam is injected to start the cooking process, and the preconditioned mix (extrudate) is then passed through an extruder. The extruder consists of a large, rotating screw tightly fitting within a stationary barrel, at the end of which is the die. The extruder's rotating screw forces the extrudate toward the die, through which it then passes. The amount of time the extrudate is in the extruder is the residence time.
History
The first extruder was designed to manufacture sausages in the 1870s. Packaged dry pasta and breakfast cereals have been produced via extrusion since the 1930s, and the method was applied to pet food production in the 1950s. It has also been incorporated into kitchen appliances, such as meat grinders, herb grinders, coffee grinders, and some types of pasta makers. A similar functional process occurs when using pastry bags.
Effects
Extrusion enables mass production of food via a continuous, efficient system that ensures uniformity of the final product. This is achieved by controlling various aspects of the extrusion process. It has also enabled the production of new processed food products and "revolutionized many conventional snack manufacturing processes". The extrusion process results in "chemical reactions that occur within the extruder barrel and at the die.

QW non-clogging sewage pump is a newly developed pump, based on the combination of the advanced technology from abroad and domestic features, which is good at energy-saving, anti-winding, no-clog, automatic installation and automatic control. This pump is excellent in transporting water with solid-particles and long fiber contained.
This pump has introduced special impeller structure and neo mechanical seals, to make it more efficient in delivering solid particles and long fiber contained water. Compared with traditional impeller, the new impeller, with spiral-flow type or double-leaf type that has an excellent delivery capacity, together with suitable volute, can improve the performance of the pump, running smoothly without any vibration.
Applications:
Sewage discharging of living plot
Sewage system of municipal works
Sewage system in factory and mine corporation
Waste water discharging of public facility
Unit to other water-discharging system
Features:
1. The impeller adopts particular large channel structure, so the drain capacity has been improved greatly. It can effectively pass the solid grain whose diameter is about 50%of the pump caliber.
2. The balanced rotor part and the proper bearing arrangement have effectively balanced the redial and axial load of pump, so it ensures the unit to run long and steadily with little vibration and low noise.
3. This type pump can adopt different installation forms according to the consumer's requirements: Single-pipe or double-pipe.
4. Mechanical seal adopts the latest material and is made with extra care. So its life is over 8000 hours.
5. The pump can be equipped with liquid-level automatic control cabinet according to the consumer's requirements.
6. The whole machine can be started and stopped automatically according to the changes of level. It doesn't need a special person to guard, so the application is quite convenient and it is easy to realize automatic management.
Note: Case of special temperature, pressure, high erosion etc, should be put forward in advance, so we can provide you more reliable models.
Working conditions:
Capacity scope: 2-800m/h
Head scope: 3-50m3
Medium temperature: -15~+60
Medium consistency: ≤ 1.3 X 103kg/m3
Rated speed: 980-2900r/min medium pH scope: 5-9
System pressure: ≤ 0.6mpa
Rotation: Clockwise rotation viewed from motor
Model Meaning
25: Pump mark of outlet diameter
8: Flow
22: Head
1.1: Matched motor power
NOTE: We supply you with custom-made pump, any inquiry will be highly welcome!

Extrusion enables mass production of food via a continuous, efficient system that ensures uniformity of the final product. Food products manufactured using extrusion usually have a high starch content. These include some pasta, breads (croutons, bread sticks, and flat breads), many breakfast cereals and ready-to-eat snacks, confectionery, pre-made cookie dough, some baby foods, full-fat soy, textured vegetable protein, some beverages, and dry and semi-moist pet foods.
