Buyers can refer to the following types of soybean meal extractor which are commonly used for extracting oils from various oilseeds:
This is one of the most frequently used extraction methods. This extraction method uses a solvent, usually hexane, to extract oil from oilseeds. The seeds are first flaked, and then the solvent is mixed with the meal to extract the oil. Finally, the mixture is separated through distillation to obtain extracted oil and oil cake meal. This method is cost-effective and efficient, especially for large-scale production.
Expeller pressing is a mechanical extraction method that applies high pressure to oilseed to extract oil. This method leaves behind a residual meal that can be used as animal feed. The main advantage of expeller pressing is that it doesn't use chemical solvents, which makes the extracted oil purer and reduces the potential for solvent-related regulatory issues.
This type of extraction is similar to the traditional solvent extraction method but uses different solvents. These solvents include ethyl alcohol or other organic solvents to extract oil from oilseeds. The extracted soybean meal can be used to produce animal feed to supply nutrients like protein and amino acids. The extracted oil is usually refined further for human consumption.
The cold meal extractor method uses lower temperatures to extract oil. This method helps preserve the nutritional value of the oil. Cold pressing is suitable for extracting oil from seeds that are smaller in size like mustard, sesame, and flaxseeds.
Wet extraction is a method that uses a liquid to extract oil from oilseeds without applying heat or solvents. This method helps reduce the quantities of toxins found in meals and oils. It is often used for seeds like oil palm fruit and coconuts.
Soybean extract can be used in the following industrial applications:
Soybean meal extractors remove oil from the beans to produce a high-protein feed for livestock and poultry. Buyers should consider soybean meal pellets that have a high protein content of approximately 44% to 48% for cattle, poultry, fish, and swine feed. This is because of the essential amino acids, vitamins, and minerals that soybean meal contains.
In food processing, soybean meal extractors are used to produce soy flour, soy protein isolate, and textured vegetable protein (TVP) for meat alternatives. Soy protein is a popular ingredient because it is a vegetarian source of high-quality protein. It also contains all essential amino acids for muscle development and overall body wellness.
In biorefineries, soybean meal extractors are used to produce green chemicals, biofuels, and bio-based products. For example, fatty acids and alcohol from resin extraction can be converted to biodiesel. Other soybean meal co-products can be converted to bioethanol and biogas as a renewable energy source.
Soybeans also contain phytochemicals like isoflavones that are extracted for pharmaceuticals. Isoflavones are compounds that serve as phytoestrogens and are commonly used in hormone replacement therapies and treatments of menopause-related symptoms. Soy lecithin, a phospholipid derived from soybean oil, is also used as an emulsifier in drug formulations to improve the solubility and bioavailability of medications.
Some soybean oil is then processed into high-performance industrial oils and lubricants for machines, engines, and equipment. This is because they offer excellent lubrication properties and environmental benefits over petroleum-based products. Also, fatty acids from soybean oil can be converted into biodiesel and other renewable fuels, contributing to greener energy alternatives.
It is important for buyers to understand the characteristics of soybean meal extractors so they can identify which one suits their needs the most. Here are some key specifications and features to consider:
Capacity
The extraction capacity of the soybean meal extractor varies by model. Smaller scale extractors have capacities of around 100 kg to 300 kg per hour. On the other hand, larger industrial extractors can process over 10 tons of soybeans per hour to cater to large oil extraction plants.
Energy Consumption
Most soybean meal extractors have an energy-efficient design to help reduce operational costs. The efficiency level varies by the type of extractor, for example, solvent extractors usually have lower energy consumption rates than mechanical press extractors.
Oil Yield
This yield is the amount of oil that can be extracted per kilogram of soybean seeds. The oil yield also depends on the method of extraction used. For example, solvent extraction yields approximately 0.5 kg of oil per kg of soybean. While mechanical pressing only yields around 0.4 kg of oil per kg of soybean.
Residual Meal Oil Content
After extraction, some oil may remain in the soybean meal. Note that residual oil content usually varies depending on the extractor used. For example, solvent extractors leave about 0.5% to 1% oil in the meal. While mechanical presses leave around 1% to 2% oil in the meal.
Dimensional Specifications
The dimensional specifications of soybean meal extractors for sale on Alibaba.com vary by model. However, small-scale extractors are usually approximately 2 meters in length and 1 meter in width. On the other hand, large industrial extractors can reach lengths of 10 meters or more. They also measure 2 meters in width.
Buyers should first carefully read the user manual of the soya bean oil extraction machine for installation guidance and safety precautions. The manuals usually provide detailed steps on how to install the components. The manual also informs users about the maintenance required for the extractor. Buyers can refer to online videos and tutorials that provide more installation and maintenance demonstrations in user-friendly ways.
Some common maintenance requirements include lubricating components like screws, blades, and motors to ensure smooth operation. Oil leaks, unusual noises, or changes in extraction efficiency are signs to look out for that indicate there is a problem in the extractor. Furthermore, users should not attempt to repair the extractor if they don’t understand the mechanics. Instead, they should call a professional to come and fix the machine.
Buyers looking to buy oil seed extractors can request the following customizations if they don’t find suitable meal extractors in stock:
Material customization plays a significant role in developing an efficient extractor that can resist high temperatures, pressures, and even corrosion. Therefore, buyers looking to place bulk orders can request for this soybean extractor machine to be made from high-graded stainless steel, alloy steel, or an improved version of steel that minimizes wear and tear. Additionally, the materials should have a good heat resistance level. This can help maintain the ideal temperature during extraction to prevent damage to the extractor.
Automatic extractors are designed with automatic loading and meal discharging systems, eliminating the need for manual labor. They are also equipped with advanced control systems to help users monitor critical parameters like meal and oil temperature, moisture content, and oil yield. Custom automatic extractors can also be integrated with existing ERP systems in oil extraction plants for improved workflow. Manual extractors, on the other hand, give users more control over the extraction settings.
Depending on the scale of buyers' operations, they can request for engine oil extractor motors to be customized with different power ratings. Smaller scale meal extractors use motors with power ratings of 1 to 5 kW. On the other hand, large-scale extractors use motors with power ratings of over 30 kW. Additionally, buyers can choose between electric and diesel-powered motors depending on the availability of electrical power in the working environment and their personal preferences.
Buyers can request the ideal size for the soybean meal extractor to be customized based on their space requirements and oil extraction capacity. Therefore, small-scale farmers should consider small oil extraction machines that are approximately 1 meter in length and width. On the other hand, large oil extraction plants should get large meal extractors that can produce a high oil extraction capacity.
The only disadvantage of customizing a soybean meal extractor is that it takes a longer time for the meal extractor to be delivered. As for the advantages, the buyer gets to enjoy a machine that is tailored to their requirements. This allows them to work efficiently and give high productivity. Customizations also help the extractor incorporate the latest technologies for improved performance and energy efficiency.
No. It is not advisable for users to perform maintenance on the soybean meal extractor themselves. Going straight to quacks to fix the meal extractor can have negative consequences on its performance and efficiency. Therefore, users should hire professionals. There is a possibility that the mechanics behind the extractor are advanced. So, it is best to let experts handle them.
The extraction method and extraction parameters are the two most significant factors that affect the residual oil content in soybean meal. The extraction method determines how efficiently the oil is extracted. While extraction parameters like temperature, time, and solvent-to-meal ratio significantly affect oil extraction efficiency.
Yes, buyers can customize the frame of soybean meal extractors to make them portable by equipping them with wheels. Airtight frames are also mounted on wheels to make them portable. This enables the extractor to be moved easily. However, the wheels are heavy-duty. This is because the extractor is heavy in weight and the work it does is also tough.
The factors farmers should consider are the power requirements of the meal extractor and the available power supply on the farm. Farmers also have to consider the efficiency of the motor and whether it has any special features like variable speed control to help them regulate the extraction process.
