Product Description
The single-screw extruder is a common extrusion equipment.Its working principle is to rotate and push materials through a single screw in the extrusion barrel to achieve mixing,plasticization and extrusion of materials.Here are some key points about single screw extruders:
Structure and working principle:A single-screw extruder consists of an extrusion barrel and a screw.The screw is located in the extrusion barrel and rotates to push the material forward.During the extrusion process,the material interacts with the barrel wall and screw to generate friction and shearing forces,thereby achieving plasticization and extrusion of the material.
Wide scope of application:Single-screw extruder is suitable for extrusion processing of a variety of materials,including plastics,rubber, food,cosmetics,etc.For the food industry,it can be used to manufacture noodles,puffed food,candy,chocolate and other food products.
Versatility: The single-screw extruder can adjust parameters such as screw speed, temperature and pressure to meet the processing requirements of different materials and products. At the same time, molds of different shapes and sizes can be replaced to produce products of different forms.
Simple operation and maintenance: Compared with twin-screw extruders, single-screw extruders have a simpler structure and are relatively easy to operate and maintain. Regular cleaning, lubrication and inspection are usually all that is required to ensure proper operation of the equipment.
Application Display
Single-screw extruders are suitable for extrusion processing of a variety of foods, including but not limited to the following categories:
Pasta foods: Single-screw extruders can be used to make various pasta foods, such as noodles, pasta, wonton wrappers, dumpling wrappers, etc. By adjusting the working parameters of the extruder and the shape of the mold, noodles and crusty foods of different shapes and thicknesses can be produced.
Puffed food: Single-screw extruders are widely used in the puffed food industry. It can extrude starch, grains and other raw materials into flakes or filaments, and then make puffed foods such as potato chips, rice cakes, breakfast cereals, etc. through puffing and drying processes.
Candy and Chocolate: Single-screw extruders are commonly used in candy and chocolate production to create various shapes of candy and chocolate products. It can extrude syrup, chocolate and other materials into specific shapes of candies or chocolate blocks, and obtain the final product by cooling and solidifying.
Cakes and Biscuits: Single screw extruders also have applications in cake and biscuit manufacturing. It can be used to make biscuit dough and produce biscuits of various shapes and textures through extrusion and cutting processes. At the same time, the single-screw extruder can also be used to make the cake body and fillings.
In addition, single-screw extruders can also be used to manufacture fruit and vegetable juices, meat products, dairy products, ice cream, condiments and other food products. For each food product, the working parameters of the extruder and the mold shape may need to be adjusted appropriately to meet the processing requirements of different food products.
Product Advantages
Simple structure: The single-screw food extruder consists of a screw and an extrusion barrel. The structure is relatively simple and easy to operate and maintain.
Wide scope of application: The single-screw extruder is suitable for the extrusion processing of many food raw materials, including powdery, granular, liquid and even semi-solid food raw materials.
Flexible adjustment: The working parameters of the single-screw extruder, such as screw speed, feed volume, extrusion temperature, etc., can be adjusted and controlled according to different food raw materials and product requirements.
Efficient energy consumption ratio: Compared with other types of extrusion equipment, single-screw extruders can usually achieve efficient extrusion processing with lower energy consumption, helping to reduce production costs.
Molding flexibility: The single-screw extruder can produce food products of various shapes and specifications, such as biscuits, bread, cookies, etc., by replacing molds of different shapes and sizes.
Easy to clean and maintain: The cleaning and maintenance of the single-screw extruder is relatively simple, reducing the workload of the operator and improving production efficiency.
