Food Extruder Machine

Normal Snack Food
Food extrusion machines are used to produce a wide range of products such as snacks, breakfast cereals,
Meat and cheese analogues, complementary foods, baby foods and other textured foods.

Confectionery
These devices can be used to produce chewy, gelatinized products such as pectin and licorice from a mixture of sugar, glucose and starch. The heat causes it to gelatinize the starch, dissolve the sugar and evaporate excess water, which is drained from the machine. The texture of the candy can range from soft to stretchy, the shape can be changed by changing molds, and a variety of flavors and colors can be added.

Breakfast Cereal
There are two types of breakfast cereals: ready-to-eat cold cereals and hot cereals (traditional cereals). To reduce home prep time, extruded cereals are cooked and modified by flaking, toasting, puffing, chopping or extruding, making breakfast a less time-consuming process.

Meat Analogs
Cultured meat, also known as meat substitutes, simulated meat, cultured meat or simulated meat, approximates the quality and chemical properties of a certain aesthetically specific type of meat. They are made from soy protein or gluten, added with starch, flavorings, etc., steamed, and extruded.

Single Screw Extruder
The single-screw extruder consists of a feeder, a single extruder barrel, a screw, a temperature and pressure control unit, a motor and a gear device. This type of extruder has a feed zone; a compression zone; and a melting or plasticizing zone. It has a slow extrusion speed and is generally used for the production of small amounts of ingredients. The material residence time is long and is suitable for extrusion processing of pellets.

Twin-Screw Extruders
It consists of two parallel screws of equal length rotate inside the same barrel, usually the internal surface of the barrel of twin screw extruders is smooth. It is more complicated than single screw extruders, provides much more flexibility and better control. Twin-screw extruders are used for high moisture extrusion, products that include higher quantities of components such as fibres, fats, etc. and more sophisticated products.

Conveyor Belt Food Extruder
The conveyor belt food extruder is probably the most common type of machine used to make snacks. It's simple to use, requiring little setup time and making it easy to produce high-quality snacks quickly and efficiently. The conveyor belt food extruder typically uses a series of rolls to push the snacks through the machine, which results in high-quality products that are evenly shaped and uniform in size.

Rotary Food Extruder
The rotary food extruder is similar to the conveyor belt snack food extruder in that it uses a series of rolls to push the snacks through the machine. However, the extruder features a rotating drum that helps to form the snacks into their desired shapes and sizes, so it is often preferred by businesses.

(1)During the extrusion process, the raw material is first ground to the correct particle size, usually the consistency of semolina.

(2)The dry mix passes through a preconditioner, where other ingredients are added depending on the target product, including liquid sugar, fat, dyes, meat, or water.

(3)Steam is injected to start the cooking process, cooking the combined ingredients.

(4)The preconditioned mixture (extrudate) is passed through an extruder, forcing the extrudate toward and through the die.

(5)The extrudate is cut to the desired length by a blade at the extruder output, which rotates around the die opening at a specific speed.

(6)The product is cooled and dried, becoming firm while maintaining porosity.
