Each is capable of making at a charge sixteen cakes, measuring about 28 in. by 12 in. and weighing 10 to 111b. each. The press rams are 16 in. in diameter and work under a pressure of 2 tons per square inch. The presses stand in a steel tank sunk into the floor. The expressed oil is caught in this tank and is drawn thence by an oil pump and forced into storage vessels. These vessels have a capacity of 50 tons, and are provided with oil taps and with additional taps whence may be drawn any mucilage which may settle out from the oil on standing. The cakes taken from the press are stripped of their bagging, and one by one are placed on the table of a power-driven paring machine F. With these machines we will deal presently. Their function is to pare off the extra oily edges of the cakes so as to trim the cakes to a more or less uniform size, and further, to recover the oily edge portions for additional treatment. The parings are passed into an edge runner G where they are reduced again to the form of meal. This meal is then returned by means of the elevator H to the kettle C, where it is mixed with a fresh charge. The edge stones are of Derbyshire grit 4 ft. in diameter by 12 in. thick. Besides reducing the parings to the form of meal, they are also used to treat likewise any broken or damaged cakes arising from the working of the presses., Hydraulic pressure is supplied to the presses by a set of horizontal belt-driven pumps J. No accumulators are used. The base of these pumps forms a cistern, whence the pumps draw their supply of pressure fluid--oil usually--and to which the exhaust from the presses is delivered. In working oil presses there are two distinct periods....show more
