Oil pressing machine

 Model  6BYL-95 Coconut oil press machine

Description

The machine is applicable for the pressing of Coconut.Also can be used to produce cottonseed, sesame, peanut, soybean, etc.The machine is mainly comprised of feeding chute, pressing cage, pressing shaft, gear box and main frame, etc. The meal enters the pressing cage from the chute, and be propelled, squeezed, turned, rubbed and pressed, the mechanical energy is converted into heat energy, and gradually expels the oil out, the oil flows out the slits of pressing cage, collected by the oil dripping chute, then flows into oil tank. The cake is expelled out from end of the machine.The machine is of compact structure, moderate floor area consumption, easy maintenance and operation.

Pressing process  

Coconut→clean→crack (or particle milling)→flaking→cooking→pressing→crude oil→filtering→finished oil

Oration principle and structure
1.Oration 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. 

2.Maintenance and Assembly/disassembly of Main parts
2.1 Pressing cage (round plates, square rods holder)
Rotate the screw shaft and remove it from the chamber. Loose the lock nut on the outlet end by rotating it counter-clock wise using a 24 mm diameter bar, loose  four M14bolts, remove ten M16 bolts which are used to connect upper and lower cases. However, after removing upper case, round plates and square rods holder can be pulled out.
2.2 Remove square rods:
After removing the holder, tap the end of one rod and take it out, then others will be   easily removed.
2.3 Assembly of rods:
 Erect the rod holder vertically and make its side with oil grooves locate downwards, better on a wooden plate, then put square rods  to touch holders inner wall circumferentially with their grooves downwards again. However, grooves of every two adjacent rods should not be touched. Then insert shins (by a hammer) properly into rods gap to let than firmly touch rods holders inner wall. As a matter of fact, whole inner wall of rods should be smooth.
2.4 Assembly of the cage:
 Put the groove side of rod the holder to face the machine body, and then insert round plates as per marks on them. Put lock nuts on to contact plates and then mount the upper case. Tighten bolts one by one.

Operating
1 Feeding must be steady and slow at the beginning to avoid blocking.

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.

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.
