Oil expeller/screw press is a mechanized system to extract an oil from seed/ raw material. For small and medium scale industry, the oil expeller is the backbone to extract vegetable oil.
Hitesh International is the leading manufacturer and exporter of complete oil extraction plants from India.
Our oil expeller has been designed by conducting vast research to achieve high oil extraction rates, less maintenance and economical prices.
1 : Preparation of seed
2 : Extraction
3 : Filtration
Kernel/seed/ cake preparation is very essential before feeding the raw material into an expeller for crushing to extract the oil. The preparatory section consists of seed cleaning to remove the impurities or trash from the kernel/ seed/nuts. After this nut will goes to decorticator or ripple mill, this machine will remove the outer shell from the nuts so that proper oil extraction can be done while feeding the kernel/ nuts into an oil expeller.
1 : Mustard
2 : Soyabean
3 : Coconut/ copra
4 : Groundnuts
5 : Palm kernel
6 : Rape seeds
7 : Corn germ
8 : Castor seeds
9 : Sunflower
10 : Jatropha
11 : Canola
Hitesh International engaged in manufacturing of oil expeller capacity 2tons per day(2TPD-150TPD).
Oil seed /nuts received from preparatory section will goes to cooker/dryer. The purpose is to maintain the moisture level below 7degrees for efficient crushing of the seed. Oil seed cells will be opened after heating the seed in cooker which results in an easy and better oil extraction. Now the oil seeds will enter into the oil expeller via feed hopper for continuous feeding into oil expeller. The fundamental principle of oil expeller is to compress oil seed via continuous pressure from screw drive. By the medium of continuous pressure, the oil comes out from the oil seed through barrel bars inside the chamber.
The cake which comes out from the expeller normally called oil cake will go to the second pressing and third pressing depends upon the oil content in oil seeds. In oil expeller it is not possible to extract all the oil from oil seeds. Few percentages of oil always remain in the cake which can extract via solvent extraction plant.
The design of worm assembly and press cage chamber is not similar for most of the oil seeds. Hitesh International oil expellers are specially designed as per quality and oil content in the oil seeds which results in high oil extraction at low cost.
Vibro separator
It is a screaming device that vibrates about its Centre of mass. The fundamental principle of vibro separator is to do separation of solids from slurry and sizing of powders. Our vibro separator comes with superior separation efficiency with less maintenance and low power consumption.
# | Screen size | Power |
---|---|---|
1 | 24” | 0.5HP |
2 | 30” | 0.5HP |
3 | 36” | 0.5HP |
4 | 48” | 1.5HP |
5 | 60” | 1.5HP |
6 | 72” | 3.0HP |
Hitesh International manufactures and exports large variety of filter press machines for the separation of solids from liquids. Once the oil comes from vibro separator to filter press small impurities are still present in the oil which is pumped to filter press for final filtration with the help of plunger pump.
1. Superior quality cast iron plates are used.
2. Higher filtration rate.
3. Plates are machined and grinded for accuracy which avoids leakages.
