Please carefully read the items marked with ★ or our company will not take any

responsibility for any results caused by them.

2. Structure and operating principle:

(I) Structure

This series of unit are mainly composed of automatic control, heating and pressing,

adjusting, driving and vacuum oil filtering parts (See figure 1) ；

1. The automatic control part consists of air break switch, AC contactor,

temperature controller and circuit automatic protection device (See figure 3)

2. The heating and pressing part consists of heater, squeezing bolt, squeezing bolt

and assembly of complete machine.

3. The driving part consists of principal axis, reduction gear box, belt pulley and

motor wheel;

4. The adjusting part consist of stretching screws, adjusting nuts, hand grip and

locknuts (See figure 4 and 6)

5 The vacuum oil filtering part consists of vacuum pump and pipelines of oil

filtering drum. (See figure 5)

(II) Operating principle

After slowing down, the power is passed to main axle and the squeezing bolt on

principal axle will rotate to push the oil plants between screw threads to continuously

advance. And the pressure will become greater and greater for the gradually reduced

space between pressing chamber and squeezing bolt and increasing oil plants density.

During pressing, heat is generated because of the friction among oil plants grains and

between oil plants and parts. So the two main factors for oil pressing technology :

pressure and heat are created, which will destroy the histiocyte of oil plants, press the

oil spill out from oil thread and push the cake out of the mouth. When the spilled oil

flows to the top of filtering drum through oil pan, the vacuum pump will draw the air

out of the drum to create negative pressure in the drum. Then the oil is pumped into

the drum through filter cloth and the pure oil is obtained for the oil residue has been

separate on the filter cloth.

3. Assembly:

(1) When the assembly is made, sufficient space shall be available all round the oil

press for working staff to conduct operation;

(2) First adjust the four anchor bolts (A) under the engine base to place the machine at

horizontal position, then adjust the filtering drum to horizon (See figure 1);

Manual book of oil press

5

(3) After the assembly, ground wire in 0.5-1m depth shall be made 3-5 m away from

the machine prior to operation.

4. Operation and use:

(1) Before use, it is necessary to carefully read the operating manual instruction and

be familiar with the performance emphasis and operating methods;

(2) Before starting-up, a complete inspection on the machine shall be made to make

sure that there are no loosened fasteners and inflexible handles. When turning around

the belt pulley with hand, all running parts shall be in good condition without any

abnormal noises. Then fill up the reduction gear box with # 20 machine oil;

(3) Loosen the locking nuts; turn around the stretching screw anticlockwise to make

the conical surfaces of squeezing bolt and cake outlet closely contact, then screw out

the stretching screw 2-3mm clockwise. After screwing up the nuts, prepare to start up

machine.

(4) Open the door of electric appliance and open the air break switch of power in the

case (placed in a suitable location) to switch on the power of complete machine;

(5) Adjust the temperature controller to 120-200℃ for pressing (depends on different

kind of oilseeds). Turn the master heating switch to heat the machine. When the

temperature of the machine reaches the fixed value, the light on the temperature

controller will change from green light on and red light off to red on and green off.

The temperature set up for the machine is 120-200℃. In winter, please switch on the

oil pan to increase the temperature for oil flowing down;

(6) Press the positive rotation button of main engine; it will start to run at

anticlockwise direction.

(7) The new assembled machine shall have 2-8 hours pressing. Slowly put the used

cake material （rapeseed cake, soybean cake, cotton seed cake or cotton shell and

paddy shell）into the hopper and repeated for times to polish the pressing chamber and

easily making out cakes. Do not put the oilseeds directly into the hopper when starting

to press;

(8) The material shall be slowly put into the hopper. The machine shall be

immediately shut down to clear up the hamper when abnormal noises happen or the

squeezing bolt axis was locked because of heavy feeding. The machine can be

restarted up after assemble. Forcefully pulling machine or reversal pouring materials

are strictly forbidden. During normal pressing, regular pattern shall be achieved.

Control the cake thickness between 0.5-2mm and there is no residue in low pressure

section but few residues in high pressure section with the proportion of residue

against oil not higher than 10%. The temperature of pressing chamber can reach

120-200℃, so the blue smoke shall be piped out by piping line from hood shield and

the hot cake shall be timely spread out to avoid spontaneous combustion. When the

temperature of the machine is too high because of long time working, electric fan

shall be used to cool down;

（9）While the squeezed oil flows to the oil filter, the button of the vacuum pump

shall be pressed to run. Then the air in the oil filter drum is pushed out, bringing about

the negative pressure. Therefore, the oil on it spontaneously flows into the oil filter

drum, leaving the oil residue on the filter cloth. After the squeezing, the vacuum pump

shall be stopped when the oil is pumped off. And the valve on the oil filter drum is

required to be opened (figure 5, 3, 4), on the filter cloth there is dry residual. The oil

filter will become clean by scraping off such residual with scraper. Then the neat oil

emit fro the bottom valve (figure 5, 5, 6);

(10) Stop

Before the stopping, the feeding shall be stopped, as well as opening the cake outlet.

Then a bit of cake scraps shall be put in and the cake materials in the squeezing

chamber shall be discharged until there is no cake put out. At this time, the machine

can be stopped. After the machine is stopped, the stretching bolt shall be rotated

clockwise one to three circles, and then cut off the power.

5. Maintenance:

(1) The lubrication shall be checked every 50 working hours. The oil cup on the

reduction box shall not lack oil. The grease shall be applied for the bearing of

stretching bolt of squeezing bolt through the hole on stretching bolt. Dry grinding is

prohibited.

(2) All lubricating parts shall be protected from dust and other impurities. The

oil in the reduction box shall be checked every year. If they are deteriorated, all of

them shall be changed.

(3) When the production reduces, or it is not normal to put out cake or oil, the

squeezing bolt shall be drawn out to check the abrasion of squeezing bolt, squeezing

bolt and cake outlet. The parts that are worn and torn shall be timely changed.

(4) Residual cakes shall be cleared away after every shift of work and the dust

and oil sludge on the machine surface shall be wiped up.

(5) If the machine will be stored for a long time after the production season,

they shall be provided with maintenance and the squeezing bolt, squeezing bars and

cake outlet shall be removed and washed, as well as applied with oil and put in dry

place.

(6) The power switch shall be cut down when to check, repair or change parts.

Maintenance with power is prohibited.

6. Squeezing methods of some main oils (for information only) :

(Ⅰ) Requirements of pretreatment procedure before squeezing the oil material

1. Drying and choosing for oil material.

The oil material shall be dried in the sun and winnowed to be clean, making

the moisture less than 10%, impurity not more than 0.5%. In particular, many users

neglect the choiceness, an indispensable pretreatment procedure, considering it is

nonessential. However, as for the oil material that is not chosen, the dust will block

the oil way, and the sand will quicken the abrasion of parts, not only having

influence on the normal work, but also shortening the useful life of squeezing bolt,

squeezing bolt and cake outlet.

2. Husking and peeling.

Peeling such oil material with shell as cottonseed and peanut will improve the

handling capacity and oil yielding rate of oil press.

3. Crushing and flaking

This machine may press oil without this procedure, especially the rapeseed, which

will be not produce obvious effect without flaking. However, as for other materials,

the flaking will be good for improving handling capacity and oil yielding rate.

4. Cooking

While the machine is applicable to cold press, the production rate and oil yielding rate

of hot press will rank above that of cold press. When the material is being cooked, the

fire power shall be appropriate and the stirring shall be even so as to prevent from

being burnt or being burnt outside while being uncooked inside.

(Ⅱ) Squeezing methods of some main oilseeds

1. Sesame

Before squeezing, the seed shall be cooked to be light gray with crack and oil will

come out if pinched. While the seed is being cooked, intense fire shall be adopted, and

the temperature shall be 120-150℃, and the cake thickness shall be 0.7-1.5mm. If it is

appropriately cooked, the oil will smoothly flow out without any residual and the cake

may be with strip shape. And the oil will be pressed out only for one time.

2. Rapeseed

For the moisture in the material of south and north is different, about 4-6% water

shall be added in north and no water added in south (depend on the inherent moisture)

before cooking. Intense fire shall be adopted to cook the seeds until they are hot

enough to burn the hands and cracks come forth, then small fire is used to cook them

to be brownish red. It is not allowed to add water during the cooking. The temperature

of the seeds that is too pressed shall be 100-120℃, and the moisture, about 1-15%.

Whether it is appropriately cooked or not, it can be determined by the oil flowing and

cake output. If it is appropriate, the oil flowing and cake output is smooth and there is

no residual in oil basically. In addition, the cake thickness is 1-1.5mm with flack

shape of brownish red

3. Groundnut kernels

The groundnut kernels shall be soaked before cooked. During the cooking, they

shall be added right amount of water to make them keep good flexibility and

sufficient moisture. When the kernels can separate from the skin and crush into two

half by pinching, they can be pressed. The cake thickness shall be 0.7mm with strip

regulating. And the oil output is smooth.

4. Soybean

The oil material shall be cooked to be light yellow before being cooked, and the

temperature shall be 100-120℃, and the cake thickness, 0.7mm. It shall be pressed

out of all oil only for one time. But the cake materials pressed for one time is too

parched, lots of proteins are lost. Therefore, twice press method is generally adopted.

The soybean shall be 60-70% cooked. The temperature for press shall be 80-100℃,

moisture, 5-6%, the cake thickness each time 1.5-2mm and the cake thickness for the

second time, 0.7mm. The cake is with strip regulate shape. The oil yielding rate is

high, and the handling capacity, great.

8. Dismantling easily worn parts :

(1) Dismantle and install the machine body

Dismantling: Pull out the worm after stopping working; screw out the bolt

connecting the bracket and the machine body; tie the machine with a rope and wooden

bar. Screw out the two nuts connecting the machine body and supporting block for

positioning (pull out the positioning end from the supporting block for positioning

along the machine body vertically), so the machine body can be dismantled.

Installing: The installation procedure is the opposite with the dismantling. But

attention should be paid to the fastening connections. Tighten the two bolts

connecting the body and bracket, but other fasteners, including bolts and nuts should

not be tightened until worm axle is installed and against the pyramidal surface of the

cake outlet.

After the machine body is installed, check the central line of the chamber is in

alignment with the center of bracket, supporting block for positioning and gearbox etc.

Judgment can be made by looking at if the worm can be smoothly moved in and out

to adjust screw rod. If not, loosen the bolts connecting the bracket, gearbox,

supporting block and the mount.

(2) Dismantle and install the squeezing bar

Dismantling: Move out the machine body. Hit one quadrangular squeezing bar with

an iron piece and a hammer until the bar comes off and other bars will come off

naturally. Same methods can be applied to dismantle low-pressure bars. Then clean

supporting mount of the body, bore of heating rings, pressing bars and cake outlet

(Please see Figure 6);

Installing: Chamber is comprised of pressing bars with high and low pressure, whose

shape has four types: A, B, C, and D. The type A and C is hexagonal prism. Type A’s

oil thread is deep and long and is all installed in low-pressure section, and the deeper

ends should be close to oilseeds inlet and no inversion is allowed. Type C’s oil thread

is short and shallow and should all be assembled in the low-pressure section. Type B

and D are both quadrangular and have no grooves. When assembling, type A and

type C’s position and direction should not be wrong. (Please see Figure 7).

After machine body, bracket and supporting block for positioning are as, hexagonal

prism and quadrangular press bars should be installed in staggered arrangement and

are kept to the inner wall of the machine body. Attention should be paid to the edges

of press bars which need to protected from damage. In case one side is damaged,

turn it over to use continually. Press bars should be installed in such a way that a

quadrangular one can be hit in with a wooden hammer in appropriate forces (See

Figure 8). If it is loose, adjust shims. Prevent shims from being deformed due to

the pressure of chamber and leakage might occur. After the press bars are installed,

Manual book of oil press

11

inner circle should be even and smooth. When the last squeezing bar is installed,

protect the inner wall of body from being damaged.

(3) Dismantling and installing worm axle

Dismantling: Loosen the nuts and screw out the worm axle and pull out the nut,

take off flat keys and then worm can be taken off. Sometimes due to the poor seal

between the worms, the residues of oil cake might be stuck and make it difficult to

dismantle. So dismantling should be made when the machine is hot. Two persons

grasp the two handles respectively and turn the main worm axle facing down; put a

support on the ground and lift the handle and hit down, and worm will come off.

Installing: Clear the main axle, worm hole and key seat. Install 4 x 10mm keys first

and then worms in order. Please see Figure 4 for the installing position and direction.

Put them naturally. If it is over tight, clear axles and worm holes and see if there are

burrs. Remove those burrs and put them back again. After the worm is installed,

place the flat keys and screws into place. When the worm axle is installed and

against the pyramidal surface of the cake outlet, uses a spanner to tighten the nuts

anti-clockwise.

(4) Dismantling and installing bearing

Dismantling: Take off the end cover, loosen the handle and remove the cap, and put

a hard wooden bar of 20-30mm diameter into the hole and keep it closely against the

main axle ends; hit the other end of the wooden bar with a hammer to move the

bearing out of screw rod; put out the stop washer in the locking nut and loosen the

nuts, take off the bearings and bushings in order (See Figure 4).

Installation: the opposite of the dismantling.
