Preparation of oil bearing material prior to its extraction is often under estimated by many processors. To achieve the best results in solvent extraction, the way in which the row material is prepared is almost as important as extraction equipments itself.
The feed stock should have a particle size small enough to enable the solvent to reach right up to the core, but at the same time not so small as to constitute 'fines' should have fairly uniform particle size in order to 'pack well' in the extractor and form a homogenous bed and should possess good percolation characteristics. Too big pieces in the feed results in high residual oil content in meal as the solvent may not be able to penetrate to the core. And too small particles or fines will lead to poor percolation and channeling effect, thus resulting in poor performance of the plant.
Fully conscious of the importance of proper preparation, glamptech have, after a long experience, developed a complete range of preparatory equipment suited for each type of raw material. Expeller cakes. Expeller cakes are adequately handled by cake breaker (702) and roller mill (703). In the former, two pairs of spiked rolls made in special alloy, running on heavy bearings and with driving mechanism, break the large pieces of cakes in the smaller pieces. These pieces are further broken down into smaller pieces in the roller mill (703), in which special corrugated rolls are utilized. The resulting product is eminently suited for extraction.
Soybeans processing requires cracking, cooking and flaking operations. Glamptech cooker is a multistage vertical vessel with steam heated bottom plates and specially designed live steam injection arrangement so arranged that the entire surface of material is uniformly covered by steam. The intrinsically designed agitator assembly moves the material and makes it pass from stage to stage. Automatic level adjustment and regulation devices are provided.
The cracked and cooked Soybeans thus obtained are transported to next operation of flaking. Flaker machine is used for flaking various prepared oil seeds thus breaking down the cellular structures and exposing larger area for efficient oil extraction. The machine comprises of one pair of chilled cast iron, dynamically balanced rolls mounted on heavy. I housings supported by suitable bearings. The gap between the rolls is adjusted as per the requirements with the help of hydraulic power pack fitted with pressure switch to generate pre-determined pressing power. Glamptech hydraulic flaker produces quality flakes of approximate 0. 25 mm to 0. 3 mm thickness, which is mo:,! Suitable for efficient extraction process.
Ricebran is powdery material which does not allow percolation of solvent easily. Glamptech pelletizing machine is specially designed for producing porous pellets with good percolation characteristics.
