Ⅰ. Soybean Oil Extruder Machine is a common equipment in the modern oil processing industry, mainly used to extract oil from soybeans. This equipment separates the oil from soybeans by mechanical extrusion. Compared with the traditional pressing method, the extruder has the advantages of high efficiency, energy saving, and environmental protection, so it occupies an important position in oil production.
Soybean Oil Extruder Machine is not only suitable for the production needs of small and medium-sized oil mills, but also can meet the requirements of large-scale industrial production. It is widely used in edible oil production, feed processing, and biodiesel. In the modern oil industry, extruders, as the core equipment for oil extraction, have great market demand.
Ⅱ. Working principle of Soybean Oil Extruder MachineThe working principle of Soybean Oil Extruder Machine mainly relies on mechanical energy to separate the oil from the raw material. The specific process is as follows:
1. Soybean cleaning and pretreatment:
- Before entering the extruder, the raw soybeans need to undergo a series of cleaning and pretreatment. First, remove impurities in soybeans, such as dust, stones, metal fragments, etc., through equipment such as vibrating screens and magnetic separators. Then the soybeans are shelled and crushed, and pressed into flakes to increase the oil extraction rate.
2. Heating and conditioning:
- The crushed soybeans are properly heated and tempered to soften the oil cell structure in the soybean flakes. This process is usually completed in a steaming pan to improve the fluidity of the oil and make it easier to squeeze out of the soybean flakes.
3. Extrusion and oil separation:
- The treated soybean flakes enter the spiral chamber of the extruder. Under the strong pressure of the spiral shaft, the material is subjected to high temperature and high pressure, and the oil is squeezed out and discharged through the oil outlet in the machine body. In this process, the oil and solid materials are effectively separated, and the oil content of the extruded bean cake is low, and the residual oil rate is usually around 5%.
4. Oil filtration and collection:
- The extruded raw soybean oil usually contains impurities and suspended matter, so it needs to be coarsely filtered through preliminary filtration equipment to remove larger solid particles. The oil after coarse filtration can be further entered into the refining stage for deep treatment such as degumming, deacidification, and decolorization to obtain high-quality soybean oil.
5. By-product processing:
- The by-products produced by the extruder are mainly soybean cake (also known as soybean meal), which is rich in protein and is usually used as animal feed or further processed into high-protein powder.
III. Types and characteristics of Soybean Oil Extruder MachineAccording to the processing technology and production scale, soybean oil extruders can be mainly divided into the following categories:
1. Single screw extruder:
- This type of extruder uses a single screw shaft to squeeze out the oil from soybeans. The single screw extruder has a simple structure and is easy to operate, suitable for small and medium-sized oil mills. This model has a moderate output and is suitable for factories with low daily processing volume.
2. Twin screw extruder:
- The twin screw extruder adopts a twin-shaft extrusion method, with a large output and suitable for large-scale production. This extruder has a high oil extraction rate and high efficiency, and is suitable for industrial production with a large daily processing volume.
3. Multifunctional extruder:
- This type of equipment can not only be used for the extrusion of soybean oil, but also can process other oil crops, such as peanuts, rapeseed, sunflower seeds, etc. Multifunctional extruders are suitable for the production of a variety of oils and fats, especially for those enterprises that need to flexibly adjust production lines.
Ⅳ.Main features of Soybean Oil Extruder Machine:
- High efficiency and energy saving: The extruder quickly completes the separation of oil and fat under high temperature and high pressure, with high production efficiency and low energy consumption.
- High degree of automation: Modern soybean oil extruders are mostly equipped with automatic control systems, which can realize automatic operation and reduce labor costs.
- Durable equipment: The extruder is mostly made of high-quality stainless steel and high-strength materials, which is corrosion-resistant and has a long service life.
- Good environmental performance: During the production process of the extruder, the emission of waste gas, waste residue and wastewater is low, which meets environmental protection requirements.
Application fields of Soybean Oil Extruder Machine
Soybean Oil Extruder Machine is widely used in the following fields:
1. Edible oil production:
- Soybean oil is one of the most consumed vegetable oils in the world, and soybean oil extruder is a key equipment in the edible oil production line. The soybean oil produced by the extruder can be directly used in cooking, food processing and other fields after further refining.
2. Biodiesel:
- In recent years, with the enhancement of environmental awareness, the demand for biodiesel has continued to rise. Soybean oil extruder can be used to extract raw oil and provide a source of oil for the production of biodiesel.
3. Feed processing:
- The soybean cake produced after extruding soybeans is rich in protein and is a high-quality animal feed raw material. Soybean meal is widely used in animal husbandry and aquaculture as a by-product.
4. Food industry:
- Extruders can not only be used for the production of soybean oil, but also for the processing of products such as soybean protein powder through different processes to meet the food industry's demand for plant protein.
Ⅴ. How to choose a suitable soybean oil extruderWhen choosing a Soybean Oil Extruder Machine, the following key factors should be considered:
1. Production scale:
- Choose the appropriate equipment type and output according to your production needs. Small factories can choose single screw extruders, while large factories need to consider double screw or multi-function extruders.
2. Equipment quality:
- The material, processing accuracy and durability of the extruder determine the service life and production efficiency of the equipment. It is recommended to choose equipment from well-known brands to ensure reliable quality.
3. Oil extraction rate:
- The extraction rate is directly related to production costs and economic benefits. An efficient extruder can minimize residual oil and reduce waste.
4. Automation degree:
- If the production scale is large, you can consider purchasing equipment with a higher degree of automation to improve production efficiency and reduce labor costs.
5. After-sales service:
- Choose a supplier with good after-sales service to ensure that the equipment can receive timely maintenance and technical support during operation.
As the core equipment in soybean oil production, soybean oil extruder machine has the characteristics of high efficiency, energy saving and environmental protection. It is widely used in many fields such as edible oil production, biodiesel manufacturing and feed processing. Choosing a suitable soybean oil extruder machine can help enterprises improve production efficiency, reduce operating costs, and improve product quality. In the future, with the continuous advancement of technology, soybean oil extruder machine will play a more important role in the oil processing industry.
