Oil Succination Machine
Using mechanical pressure and heat rather than chemical solvents, these machines extract oils from seeds and nuts. They also peel the products and separate lightweight shells from heavier nut insides.
Features include a waste oil piston pump with on/off valve, vacuum gauge for monitoring the unit performance, extra large capacity suction filter and 3 m of suction hose.
Oilseed Press
Most oil-rich seeds and nuts can be pressed with a mechanical screw press. Unlike hydraulic presses, this machine uses friction and continuous pressure to move and compress the raw materials through a caged barrel-like cavity. It extracts oil from the seed and forms it into a hardened cake that’s then removed. This process can achieve higher oil yields than hydraulic presses.
Seeds must be pretreated or cooked before pressing to reduce moisture content and ensure proper oil extraction. Anderson offers a wide range of conditioning equipment that accelerates cooking times and reduces the cost of heating and conditioning oilseeds. This includes our Extruder, which heats, cooks and dries in a single step. Most oilseeds benefit from cooking before pressing, but fibrous, low protein crops such as palm kernel and copra need less time to help rupture the cells that hold the oil inside them.
Manufacturers suggest removing the barrels and screws and cleaning them after shutting down the press to avoid contamination or buildup. However, if the feed flow to the press has been shut off OIL SUCTION MACHINE and the press is going to be restarted soon (within a week), leaving the press alone may be sufficient.
After the feed flow is turned on, it will take several seconds to over a minute for the meal and oil to start flowing out of the oil holes in the barrel. It is important to wait until the squeezing volume slows down significantly and then stop the flow of oil.
Oilseed Extractor
Oilseed extractors are used in the production of a wide variety of products including food, feed, nutraceuticals, cosmetics and industrial lubricants. Extraction is accomplished either mechanically using a screw press or by solvent extraction. Solvent extraction is the standard practice in today’s modern oilseed-processing plants. Mechanical oil expression is rarely used except for small on-farm operations.
Solvent extraction utilizes selected organic solvents which dissolve the oil from pretreated oilseeds or pre-pressed cakes. The resulting mixture is called miscella and it is discharged from the extraction vessel. The miscella is then pumped to the desolventizer tower where it is stripped of solvent by heating. The separated vapor and the crude extracted oil are collected in separate vessels.
Extraction can be a batch or continuous process. Generally, it is best to heat the seed prior to the press in OIL SUCTION MACHINE order to reduce the amount of energy needed for expressing the seed and to maximize oil yield. The optimum temperature range is 100 to 160 degrees.
Many different types of extractors are available on the market. Some are rotary or horizontal belt type while others are percolation or continuous loop types. All these types work to obtain high oil yields with low undesirable components and to produce a quality meal product. Extractors are designed to be efficient and economical to operate.
Oilseed Separator
Most oilseeds have a husk or shell that contains a small amount of oil. The husks reduce oil yield in the extraction process, and they cause increased wear of the extraction equipment due to their abrasiveness. Hulls also release soluble compounds into the extracted oil that affect the flavor, color and wax content of the pressed cake. Dehulling increases the efficiency and capacity of oil production.
In order to prepare the seeds for oil extraction, the seed must be cleaned, dried and dehulled. The seed must then be reduced in size by a variety of methods such as shaking conveyor belts, coarse screens and reels or vacuum. Usually the seed is then cracked and cooked to give it proper elasticity for pressing. This stage is also known as tempering. This process increases the yield of pressed cake, improves flaking performance and increases extraction efficiency.
The conditioned/cooked seed must then be separated into its components: oil and solids. To separate the oil, a separator is used. The solids are collected in the sediment holding space of the vessel. A specialized separator can be used for refining of press oil and seed oil to obtain a high quality product. The agitation, special baffling and coalescing packs that are fitted to separators allow for effective separation of nonsolution gas that may be mechanically locked in the oil by surface tension and oil viscosity.
Oilseed Filter
As the oilseeds go through the various steps of processing, they may leave some solid particles in the oil. Filtration equipment like plate and frame filters or a decanter centrifuge is used to remove these remaining solids and impurities from the crude oil. This oil can then be filtered again to ensure the final product is as pure as possible. Commercial edible cooking oils are typically known as RBD oil because they are Refined, Bleached and Deodorized. This process removes any residual solvent traces as well as unwanted flavors, colors and odors leaving you with a clean, neutral tasting cooking oil.
Solvent Extraction
There are several different methods of solvent extraction including hexane, butylene and isopropyl alcohol which are all commonly used. However, public concerns over the use of organic solvents as well as government scrutiny has led to the search for alternative techniques. One of these alternatives is the percolation extractor which works much like a coffee percolator. Heated solvent is poured over the prepared oilseed and then redirected through it again in a countercurrent pattern. This removes more and more of the solids and leaves you with a higher quality of crude oil.
After the crude oil is extracted, it goes through a series of refining processes to improve its color and flavor. Some of these refining steps include degumming (removal of phospholipids), neutralization, bleaching and deodorization. These are all steps which are beyond the scope of a small-scale producer and would be too costly and time consuming.
