At present, we often see a variety of edible oils in our lives. In the manufacturing process, the machine has also changed with the technological changes of the new era, and many varieties have appeared. A new type of hydraulic press has appeared on the market. The shortcomings of the previous hydraulic press have been improved in all aspects. The machine continues to maintain the advantages of simple structure and long service life of the hydraulic press. The oil produced is rich in aroma and dry, and does not foam when eaten, which is very popular among consumers. The following are some models:

How to choose an oil press? Classification of oil presses

1. Hydraulic oil press, which has basically been replaced by the screw oil press mechanism. It is a static hydraulic oil extraction, with low oil rate, small single machine, and high equipment oil pressure. The area is large, the workshop needs to be insulated, and the operating conditions are poor. However, hydraulic oil has the advantages of simple structure and low power consumption. It is suitable for drying some dispersed oils (such as rice sugar, wild oil) and oils that need to maintain special flavor or nutrition (such as cocoa beans, olive oil, sesame, etc.). In addition, it can also be used to squeeze oil or wax to separate bran.

2. Screw oil press

How to choose an oil press? Oil press classification
Screw oil press is one of the most widely used oil press equipment. It has the advantages of continuous processing, large output, short working time, high oil yield and low labor intensity. The main component of the screw press is the pressing chamber, which consists of an extrusion chamber and a screw shaft rotating in the extrusion chamber. Its working process is to use the reduction of the spiral lead of the screw shaft or the gradual increase of the root circle diameter to continuously reduce the volume of the compression chamber space, thereby producing a compression effect. The oil is squeezed out of the groove of the press cage, and the residue is pressed into debris, which is continuously discharged from the end of the press shaft.

3. New screw oil press

3.1. Increase the size of the extrusion chamber: adjust the pitch, increase the pressure of the extrusion chamber, and further improve the oil yield.

3.2. Improve the level of pressing: from the original two times to three times, from the original three times to four times and five times, the yield of finished oil is effectively improved.

3.4. The pressure chamber is equipped with an oil guide groove: The pressure chamber of the equipment is equipped with an oil guide groove, which can quickly separate the oil from the filter cake, improve the oil yield, and prevent the squeezed oil from soaking into the filter cake residue again.
