Small extrusion machine

Types of small extrusion machines

The small extrusion machine refers to a compact device or equipment that can be used in the extrusion process of leading materials. There are two common types of small extrusion machines as follows:

• Food small extrusion machines

  The food small extrusion machine is a small device that can widely be used in the food industry or related areas. It can be used to produce various food products, such as grains, bread, pasta, beans, and so on. The food small extrusion machine is able to change the structure of food material by high temperature and pressure. It is not only able to change the taste and flavor of the food but also can improve the nutritional value of it at the same time. Furthermore, the machine is capable of producing food with different shapes and sizes through diverse molds and cutters. This creates great opportunities for people to develop and design new food products. Overall, small extrusion machines for food are important devices in food processing factories. They help produce various food products, improve food quality, and meet the needs of different customers.

• Plastic small extrusion machines

  The plastic small extrusion machines are designed to process plastic materials. They are widely applied in the production of plastic products, such as pipes, profiles, sheets, and films. These machines work by melting the plastic materials and then pushing them through the die for cooling and solidification. Plastic small extrusion machines are available in various types and specifications to satisfy different production requirements and scale of operations. They have the advantages of high efficiency, continuous operation, and precision control. In summary, plastic small extrusion machines play an indispensable role in the plastic processing industry. They facilitate the manufacturing of diverse plastic products, thereby satisfying various industrial and commercial demands.

Specification and maintenance of small extrusion machines

Specification of small extrusion machines

• Die and cutter: Small extrusion machines come with dies of various sizes and shapes to form specific food products. Cutters then slice the extruded product to the desired length.
• Temperature control: These machines feature temperature control systems that regulate the temperature of the extruder barrel and die. Proper temperature control is essential for achieving the desired food texture and quality.
• Feeding system: The feeding system includes a hopper and conveyor belt that ensure a continuous and uniform supply of raw materials to the extruder. Some small extrusion machines have a preconditioner that moistens and warms the feedstock before it enters the extruder.
• Power source: Small extrusion machines can be powered by electricity, gas, or diesel. Power requirements vary depending on the machine's size and production capacity.
• Worm gear motor: A small extrusion machine will come equipped with a worm gear motor that is responsible for feeding, cutting, and pushing the food item in the die. Normally made of stainless steel, it resists corrosion and lasts long. It can be chosen in different speeds, depending on the type of food that will be extruded.
• Cutting mechanism: The cutting mechanism in a small extrusion machine can be a rotary or paddle cutter or a flat cutting mechanism. It is usually designed as a stainless steel blade with a sharp edge for clean, precise cuts. The type of cutting mechanism will vary according to the process needs.

Maintenance of small extrusion machines

To keep the small extrusion machine running smoothly and producing quality extruded food, a regular maintenance schedule should be followed.

• Daily clean: After the production is over for the day, all parts of the machine that have come into contact with food should be cleaned. Hot, soapy water is usually enough, but in some cases, a chemical descaler might be necessary.
• Weekly oiling: All moving parts of the small food extrusion machine should be oiled weekly to ensure smooth, frictionless movement and prevent excess wear and tear.
• Monthly inspection: Parts like conveyor belts, screws, and other moving components should be examined monthly to check for damages or any signs of excessive wear and tear. They should be immediately repaired or replaced to avoid hindering the production process.

Uses of small extrusion machines

• Food industry

  Small food extrusion machines are widely used in the food industry to make various food products like snacks, pet food, pasta, and morning breakfast cereals. For example, extrusion machines for snacks can process corn, wheat, rice, and other raw materials into puffed snacks, fried snacks, progress intricate shapes, and improve the chewing texture. Furthermore, small extrusion machines are also employed in the food industry for food chromatography and other testing purposes.

• Plastic industry

  In the plastic polymers industry, small extrusion machines can knead, foam, and extrude polymeric materials and other plastic materials into films, pipes, sheets, and other products. Besides, mini extrusion machines are convenient for researchers to test the behavior and performance of different plastics when they are extruded.

• Rubber industry

  Small rubber extrusion machines can shape, foam, and process mixture materials, such as making rubber seals, gaskets, and other products. They play a crucial role in the early stages of product development and prototyping in the rubber industry.

• Medical industry

  Small plastic extrusion machines can produce various medical products, including catheter tubes, medical pipes, etc. These products usually feature high precision, sterility requirement, and quality control, which can be achieved by small extrusion machines.

• Research and development

  Small extrusion machines are commonly used in research and development laboratories. In universities, scientific research institutes, and technical colleges, they can be used to explore new materials and processes, as well as to optimize and improve existing extrusion technologies.

• Other emerging small extrusion uses

  The 3D printing extrusion machine is mainly used to print food, medical, and personalized products. At the same time, the plasma arc welding wire feeding extrusion machine can produce welding wires. Moreover, the micro-extrusion machine is used to manufacture micro-scale components in the electronics, optics, and microdevices industries.

How to choose small extrusion machines

Several factors should be considered before purchasing or sourcing a custom small extrusion machine for sale.

• Production output and scalable capability:

  A small extrusion machine with scalable capabilities enables the gradual increase of production output as market demand grows, typically without the need for major equipment upgrades or modifications. Fitting a unit with this feature can be beneficial and economical, as it will enable the business to meet market demand by simply increasing its production capacity.

• Versatility:

  Many small extrusion machines have versatile capabilities and can process different types of materials, such as plastics, food, and chemicals, which can be a great advantage for businesses, as they will be able to work with various materials without the need for separate equipment.

• Quality control systems:

  Typically, a small plastic extrusion machine is fitted with quality control components like pressure sensors, temperature monitors, and moisture detectors, which are essential for maintaining consistent product quality and minimizing defects. Having this component can be quite advantageous to the overall production process, as it can help reduce product rejects and manufacturing waste.

• Maintenance and service:

  Investing in an extrusion machine with low maintenance requirements and high reliability can help minimize downtime and production interruptions. A small food extrusion machine that is easy to clean, maintain and operate can significantly reduce production costs by streamlining manufacturing processes and minimizing the need for routine equipment repairs.
