Structure of the Screw Oil Press

 

Screw type oil press machine is mainly composed of feeder, gearbox, pressing cage, screw shaft and machine stand etc. Pressing chamber is the key part of the machinery which including pressing cage and a screw shaft rotating in the cage. You can also equip the expeller with motor, diesel engine, or electrical control cabinet as you like. An electric cabinet can help control the whole working procedure.

 

How Does a Screw Oil Press Work?

A screw type oil making machine that presses oil seeds through a caged barrel-like cavity. Raw materials enter one side of the press and waste products exit the other side. The machine uses friction and continuous pressure from the screw drives to move and compress the seed material. The oil seeps through small openings that do not allow seed fiber solids to pass through. Afterward, the pressed seeds are formed into a hardened cake, which is removed from the machine.

The Feeder of the YZS Oil Pressing Machinery

The picture shows the inside part of the feeder for our YZS-Series oil pressing machinery. It is not just simple reversed fastigiated container to let the materials let down itself, but with a screw device and a stirring rod in the middle of the machine. When you turn on the oil press, put the materials in the feeder, the screw device will turn round to help feed the materials to go down to the chamber of the oil press smoothly and effectively. With this device, it avoids the blocking in the feed inlet of the feeder, improve the effect of the machine highly, and the stirring rod also have certain effect on mixing the materials before pressing oil.

Preparatory Work Before Starting an Oil Press

 

Tighten every bolt,nut, check is there any loose or damage in the parts. Lubricate sheave and turn it make sure it is movable or intervented with other parts.
Remove any foreign articles, e.g. stones, iron scraps etc. to avoid damaging the machine.
Before operating, adjust clearance between screw shaft and cake outlet ring by return the shaft for 2-4 circles when they touched against each other. After adjustment, operation the machine idly for 5 minutres, make sure there is no any unusual sound, and then feed in.

 

 

Pressing Methods for Some Main Material

 

Soybeans: There are two ways of extruding soybean oil. They are hot pressing and cold pressing. (1) Hot Pressing:  Soybeans – Selecting – Prepressing – Heating -- Pressing.
First select soybeans and remove foreign particles, then soften the material by breaking and adding water of 7- 8% and
then steam them to 115C, beans will be ready for pressing.
(2) Cold Pressing:Soybeans -- Selecting-- Pressing (in case of adequate water content).

 

 

Rape Seeds: Methods of hot pressing and cold pressing can also be used to extruding rapeseed oil. Hot pressing is recommended for the reason that oil extracted by the method of hot pressing is of higher quality and higher oil output rate.

(1) Hot Pressing:  Rapeseeds – Selecting – Prepressing – Heating -- Pressing.
When using the method of hot pressing, to remove foreign particles by selection, then check water content as described above , in
case of too dry.  Add 2.5-3% of water, normally two times extruding is enough.

(2) Cold Pressing:  Rapeseeds -- Selecting-- Pressing (in case of adequate water content).
When using the method of cold pressing, pre-press and heat the seeds after selecting the material. Add 2-3% .of water and await
till look coffee color and temperature 110- 120C, then ready for pressing.

 

 

Groundnuts Kernel: Cold and hot pressing are both available, but hot pressing methods have better effect than cold pressing. Firstly crack or pre-press groundnut kernels then steam them for 1.5-2 hours, temperature should control about 120C and the water content control about 3%. Normal pressing starts at temperature of 85C or crack them firstly and at a pol. add 7- 8% of water. Look coffee color will be ready for pressing. If groundnuts with shells, you should remove the shell in advance by a peanut sheller.
