Small Peanut Oil Presser Machine Stainless Steel Made to Last High Oil Yield.
Screw oil press works by physical squeezing,with obvious advantages of low investment,high oil yield,easy to operate,easy to maintain and wide application ,e.g peanut,rapeseeds,soybeans,cotton seeds,tung seeds,palm kernels etc.
This model 6YL-80 oil press is an advanced spiral oil press, characterized by its high oil output rate with good l quality, simple design, easy to use and continuous operation.
This seed oil press can be used to press various raw materials, can be used as peanut oil press, beans oil press, rape seed oil press, cotton seeds oil press, sunflower seed oil press, coconut oil press, grass seed oil press and etc.
Application:
This screw oil press is advanced expeller which is widely used in pressing oil from vegetable oil seeds, such as soybean, peanut, sunflower seeds, cotton seeds, sesame, tea seeds, copra, jatropha seeds, castor seed, etc. And the product oil is for both edible and biodiesel fuel purpose. It has advantage of high efficiency, low consumption, simple operating, stable function, easy maintenance, high productivity and high oil output.
Advantage:
1.Simple and easy operation,one key to start without other operating
2.The residual oil content does not exceed 7 percent
3.Reliable transmission systems are mostly helical gears with greater torque
4. Pure copper motors are more powerful and less failure rate
5. Reasonable design and configuration of strip and round row ensure faster oil output and higher oil yield
6. Stainless steel oil guide plate is cleaner and more sanitary
7. Advanced automatic stirring forced feeding system ensures the uniformity and continuity of feeding
8. Convenient and labor-saving adjustment and disassembly system facilitates product adjustment and maintenance
| Oil name | Handling capacity per 24 hours (Kg) | Oil production per 100 kg | Residual oil percentage of dry cake (%) | |
| rapeseed | Hot Press | 1900-2400 | 30-35 | 7.5-8 |
| peanut | Hot Press | 1900-2400 | 35-45 | 7 |
| Soya bean | Hot Press | 1800-2300 | 10-14 | 6.5-7 |
| sesame | Hot Press | 1900-2400 | 44-47 | 6.5-7.5 |
| cottonseed | Cold pressing | 900-1200 | 10-14 | 5.5-6.5 |
Extruding methods of several raw material:
1 Bean : two ways , cold and hot extruding.
(1) Cold extruding :bean-selecting-pressing (in case of adequate water content).
(2) Hot extruding : bean-selecting-per-pressing-heating(steaming etc)-pressing.
Firstly, selecting beans and remove foreign particles, then soften by breaking and adding water of 7-8%,and then steam them to 115C; beans will be ready for extruded.
2 Rape seeds: also, cold and hot extruding for your choice, but normally hot extruding is recommended.
Cold extruding : selecting -pre-pressing.
Hot extruding: selecting -pre -pressing-heating(steaming etc)-pressing.
When hot extrusion, 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.
When cold extrusion, after selecting , to pre-press and heat them, During heating, add2-3%of water and await till look coffee color and temperature 110-120C, then ready for pressing.
3 Groundnuts kernel, cold and hot extrusion are both available ,yet prefer hot pressing. When hot pressing ,firstly crack or pre-press, then steam for 1.5-2 hours, temperature about 120C.water content 3%will be good. Normal pressing starts at temperature of 85C. or crack them firstly and at a pot, add 7-8%
of water, look coffee color will be ready for pressing.
4 Groundnuts: remove shell first and remove red peel of the kernel ,then press for two times, Sound indicates it is too wet and need drying. In the case of poor cake moving out, mix about 20%of with them may help.
operation principle:
When oil presses operating prepared material enters extruding chamber from the hopper and then moves forwards by the rotating pressing screw and is pressed. Under the high-pressure condition in the chamber ,friction between material and screw ,between material and chamber will be created ,which also creates friction and relative movement among material particles. On the other hand, root diameter of the pressing screw caries larger from one end to the other ,hence. When rotating ,it not only pushes particles moving forwards but turns them outwards as well ,meanwhile ,particles adjacent the screw will rotation along with screw' rotating ,causing every particle inside the chamber to possess different speed. Therefore relative movement among particle creates heat which is necessary during manufacturing because of helping protein change property ,damage colloid ,increase plasticity ,decrease oil's elasticity ,resulting in high oil productivity.
Machine Operation:
1 preparations before operating
1.1 12kg of lubricant needs to be filled into the gearbox.
1.2 After installing the machine, check whether lubricant has been filled in, bolts have been tightened, and handles are operable.
1.3 Check large pulley whether it is loose or blocked, repair it if necessary.
1.4 Adjust the tightness of the belt, switch on the motor and check its rotation direction.
1.5 Loosen the lock nut and tighten the screw to its end, then loose it for3-4circles and then tighten it again for half circle to assure the gap of the residue cake outlet.
2 Operating
2.1 Feeding must be steady and slow at the beginning to avoid blocking
2.2 In the case no cake is extrude outward,return back the screw for 1-2circle .If there is still no cake is observed,machine needs to be shut down and checked ,However, in any case, operating the machine backward is absolutely prohibited normally ,cake looks like tile but not sticky ;thickness is 1-2mm ,inner side is smooth ,out side creases and no oil the surface is allowed.
Cake thickness adjustment: Rotating the adjusting handle clockwise will make the cake thicker, otherwise will make it thinner. Each circle of adjustment (by adjustment bolt left hand T 165x6)will change the thickness 0.4-0.5mm.
2.3 When machine is operating, oil extruding and residue outlet need be checked
Frequently .Normally, most of oil will flow outward from square rods and several front round plates. Broken cake residue indicates the material is too dry; steam emerging from the cake residue indicates that it is too wet; In any case, water content in the raw material must be adjusted from time to time.
Slag slice emerging indicates too much water content and power-like slag low water content .Loose round plates will cause too much slag flowing outwards. However, adequate water content will cause slag flowing outwards from square rods; little slag from round plates is allowed. In a word, water content affects oil output rate, it needs adjusting properly.
3 stopping
3.1 Repeatedly move screw forwards and backwards for several times and let all material resided in the chamber goes out and adjust the cake to the possible thinnest, then stop the machine.
3.2 When machine stops caused by any accident, power supply must be shut down first, then rotate large pulley manually backwards, let the material return out. Then pull out the shaft and clean it. In the case the shaft could not be pulled out, remove the upper case and loose lock nut, separate round plates and clean them one by one.
Failures and removal
| NO | Failures | Reasons | Removal |
| 1 | Sudden stop, shaft blocked |

1.Carefully operating as per the manual. 2.Note motor sound and current value |
| 2 | Low oil output |
|
1.Operating as per the manual. 2.Loosen tightening nut to drive slag off. 3.Replace worn parts. |
| 3 | Oil return to hopper |
|
1.Loosen tightening nut. 2.Adjust cake thickness and add cakes into chamber to drive oil off |
| 4 | Oil spot on cakes |
|
1.Operating as per the manual 2.Loose tightening nut. 3.Replace worn parts |
| 5 | Dark and viscous oil |
|

| 7 | Raw material can be fed |
|
1.operating as per manual 2.cotton seeds prepared |
| 8 | Cracked residue appears at the outlet severely |
|
1.operating as per manual 2.replace worn parts |
Safety:
Following items are strictly requested to be obeyed.
1 During operating, hands or metal rods are strictly prohibited to enter the hopper to touch cakes.
2 Tightening the screw shaft to its dead end is prohibited before starting or during operating, which might cause slag outlet to contact cake outlet ring, resulting in wearing.
In the case of storage, oil dirt on machines surface and slags on each part need to be taken off. Paint
rust-resisting grease and keep in dry place. Case needs to be covered to prevent dirty foreign particles from entering.
