Large Screw Oil Press

 

Our Large scale screw oil press is a continuous oil expeller equipment used widely in cooking oil mill, suitable for cottonseed, rapeseed, castor bean, sunflower seeds, peanut and other oilseeds with high oil content.

One of the main advantages of a large scale screw oil press is its ability to process a large quantity of oilseeds in a short period of time. These machines typically have a high processing capacity, ranging from several hundred kilograms to several tonnes of oilseeds per day. The large-scale production capability of screw oil presses makes them ideal for commercial edible oil production.

Another advantage of large scale screw oil presses is their efficiency in oil extraction. The machines use mechanical pressure to crush the oilseeds and extract the oil from them. The oil is then filtered and purified to produce high-quality edible oil. The use of mechanical pressure ensures that the oil retains its natural flavor, aroma, and nutritional value, making it a healthier option for consumers.

Model ZX screw oil press is the large-sized equipment of continuous press and have obtained ISO9001-2000 authentication.

It’s suitable for pressing cottonseed, rapeseed, tung seed, sunflower seed, groundnut seed and other high oil contained plants.

Its characteristics are high capacity, low power consumption, low cost in running, the construction of the press cake is soft but not fragmentary, and the solvent is apt to infiltrate, lower oil in cake. It’s the excellent choose of press equipment for the large and medium-sized oil factory.

 large screw oil press process characteristics

1. this machine has high capacity, low power consumption, low operation cost, pre-pressed cake structure loose but not crushed;

2. easy to solvent penetration, residual oil rate is low, is the ideal of small and medium-sized oil plant equipment.

Main Structures

The pre-squeezing machine is made up of the following main components: steamer, feeding mechanism, squeezing cage, squeezing screw shaft (including the cake adjustment mechanism) and transmission.

1. Steamer

This equipment is a vertical three-tier steamer, similar to a typical vertical auxiliary steamer, mounted on a bracket of the frame. Its drive motor is included in the total driveline and steaming can adjust the temperature and moisture of the raw material before it enters the press chamber so that it reaches the requirement of pressing.

2. Feeding Mechanism

The working part of the feeding mechanism is between the discharge port of the steamer and the feeding end of the squeezing shaft. It consists of the squeezing shaft with screw blades at the lower end and the falling cylinder. The entrance of the cylinder has a rotary control valve for controlling the falling flow. There is a hopper under the valve, from which the falling conditions can be observed and the material could be taken out as samples during pressing.

3. Squeezing Cage and Squeezing Screw Shaft

The squeezing cage and squeezing screw shaft are the main components of this equipment. Firstly, the material is pressed down by the feeding mechanism and continuously enters into the space between the squeezing cage & the squeezing screw shaft (called squeezing chamber). Due to the rotation of the squeezing screw shaft and the squeezing chamber gradually reduce the gap, the material is under intense pressure and most of which is pressed out of oil, next, the oil would flow out through the gap of squeeze cage.
