Why Pay Attention To Twin-screw Extruders?

Why pay attention to twin-screw extruders?

1. Focus on industry needs:

At a time when the leisure puffed food, breakfast cereals, pet food and other industries are developing rapidly, manufacturers have put forward higher requirements for the efficiency, stability and versatility of processing equipment. As a core equipment integrating mixing, maturation, molding and other functions, the twin-screw extruder can accurately match diversified production needs and become the key to industry upgrading.

2. Why apply twin screw extruder?

The twin-screw extruder has become the core equipment for the production of puffed food due to its high production capacity, flexible adaptability and stable performance. Jinan Arrow Machinery's ETT, SLT and other series of models cover multiple fields such as snack foods and pet feed through differentiated configurations, providing strong support for enterprises to reduce costs and increase efficiency. With the iteration of technology, this type of equipment will further promote the development of the food industry towards intelligence and diversification.

3. How does a food extruder work?

The core working process of a twin-screw extruder can be summarized as four stages: material conveying, mixing and shearing, heating and maturation, and molding and extrusion. When the food raw materials enter the barrel, the two intermeshing screws rotate in the same or opposite directions driven by the motor, and push the materials forward through the friction between the screw ridges and the inner wall of the barrel. During the conveying process, the special thread structure of the screw subjects the material to strong shearing, compression and stirring, achieving uniform mixing of different raw materials. At the same time, the heating device outside the barrel (such as electric heating or steam heating) and the friction heat generated by the shearing of the material work together to rapidly increase the temperature of the material and complete the maturation, gelatinization or puffing reaction. Finally, the material that meets the process requirements is extruded through the die under the thrust of the screw, and is processed by the cutting device to form a food product of a specific shape.

4. What are the advantages of twin screw extruder?

• From the application scenario, this type of equipment can cover leisure puffed foods 、breakfast cereals (corn flakes)、plant protein products、pet food and aquatic feed .The extruder is suitable for large, medium and small food processing plants, pet food production enterprises and other production entities of different sizes. In food industry-intensive areas , as well as markets with strong demand for pet food, the application of twin-screw extruders is particularly extensive.

• High degree of automation: From the transportation, mixing, extrusion of raw materials to the molding and cutting of products, the entire production process can be precisely controlled through an intelligent control system, which greatly reduces manual intervention and improves production efficiency and product quality stability.

5. What sets us apart?

As a representative of the industry, Jinan Arrow Machinery has formed six series of twin-screw extruders, including ETT and SLT, to meet different grades of needs through differentiated configurations. Its high-efficiency series models have become the mainstream of the market with its production capacity advantages, which has also made the technical characteristics and application value of twin-screw extruders the focus of industry discussions.

(1) Core advantages of equipment: a comprehensive breakthrough from technology to performance

• High-efficiency series (E type): By optimizing the screw design, the material throughput is increased by 20%-30%, and the output is increased by more than 20%-30% at the same time.

• Adjustable aspect ratio: Different aspect ratios (barrel length / screw diameter) are suitable for different product types. The number of barrel sections can be adjusted according to the product type and the required output, thus achieving "one machine with multiple outputs"

(2) High-quality configuration and durability

• Material of core components: The threaded section material is wear-resistant and has excellent performance; key components such as the barrel and mandrel are made of Asia-Pacific stainless steel to ensure food hygiene and safety.

• Patented design: The distribution box has a unique patented design with a low failure rate and a design life of more than 36,000 hours; the elastic coupling is equipped with a yellow warning shield, taking into account both safety and stability.

(3) Intelligence and ease of operation

• Flexible heating method: Supports electric heating (such as ETT, SLT series) or steam heating (such as WYT series), and can accurately control the temperature according to product requirements.

• Control mode adaptation: The ETT series host is standardly equipped with a touch screen, and the SLT series host can be optionally controlled by buttons, which is simple and easy to operate.
