What Are the Machines Used for Getting Edible Oil?

Online, May 24, 2013 (Newswire.com) - Generally, there are two types of machines that can be used for oil extracting: hydraulic oil press and screw oil press. Below are a general introduction to these machines for your reference.

Hydraulic Oil Press Structure

Hydraulic oil press is mainly composed of three parts:

1.Main body: including bottom-board, column, pressing chamber, drip tray and nuts.

2.Hydraulic transmission device: consists of transmission shaft, worm wheel, worm, gear pumps,

high-pressure pump, relief valve, etc.

3.Electrical system: important part of the press which supplies power with least energy cost.

Hydraulic Oil Press Characteristics and Performance

1. Widely applied to press peanuts, sesame, rape seeds, almond, etc.

2. Reasonablely designed pressing chamber ensures high oil yield.

3. The drip tray is equipped with heating controlling system which can adjust the temperature of crude oil; thus it can work at any season.

Screw Oil Press Working Procedure

Screw oil press uses the electric motor or diesel generator set as the engine. Before pressing, pre-processing is necessary to get cleaner oil seeds. At the same time, you can turn on the heater switch to pre-heat the pressing cage. About 10 minutes later, when the temperature is high enough to meet the pressing degree, the operator can feed the oil seeds into the machine either by labor or by alto elevator (can ensure the continuous feeding). With the constantly feeding and rotation of the screw shaft, the space between the rings and the pressing screws is much smaller, which tightly squeezes oil from the seeds.

Screw oil press can be divided into two types: screw oil press and integrated screw oil press. The main difference lies in an integrated screw oil press usually consists of an electric cabinet control system and an oil filtering vat.
