Mechanical Screw Presses ( Oil Expellers ) are commonly used for extraction of oil from various oil seeds, nuts, beans etc. either for full press or pre-press. Full press extraction screw presses / expellers are generally used by small and medium capacity oil mill plants while pre press extraction with solvent extraction process is generally used by large capacity plants.
UMAS offers equipment and systems for full press and pre-press oil mill plants. Maximum oil is removed in full press process (using Oil Expellers) leaving the cake with about 5-8 % oil content. For the solvent extraction process, the preparation process is almost the same as that for full press process with the difference that the pressed material shall contain residual oil in the range of 15-20%. Such material is fed into the solvent extraction plant where the remaining oil is reduced to 0.5 to 1.5% depending on various factors.
UMAS MAX SERIES OIL EXPELLERS ARE ALL STEEL FABRICATED MACHINES WITH EXTERNAL GEAR BOX , CAST STEEL CHAMBERS AND CAKE THICKNESS CONTROLLER. THE MACHINES CAN BE SUPPLIED WITH A GEAR BOX MANUFACTURED BY RENOWNED COMPANIES OR OUR OWN MANUFACTURED GEAR BOX .
Capacity 8-10 TPD in Single Pressing.
Cookers / Heating Kettles are used for proper heating and conditioning of the oil seeds prior to expelling. Controlled heat and moisture open up the oil bearing cells for maximum oil yield.
A bucket elevator is a mechanical conventional conveying solution to lift material up to a certain elevation. Elevators are used in oil mills for lifting seed or cake and to feed the machines / equipments automatically.
A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a "flighting", usually within a tube, to move liquid or granular materials. Screw and Redler conveyors are used for conveying the seeds , cake and oil with foots automatically.
For efficient and automatic weighing and bagging of cake.
A unique device for removing/replacing Worms and Collars from the Expeller Shaft. Different sizes of Worm Pullers available for different brands and capacities of Expellers. All hydraulically operated.
Besides manufacturing spares for their own machinery / equipment, UMAS also manufacture spares for other popular brands of oil mill machinery and its clients are fully satisfied with the quality and performance of the products.
