Using Methods and Processes of Hydraulic Press Machine

Hydraulic press is also known as hydraulic oil, sesame oil machine. Hydraulic oil press is a kind of oil press which has the most simple operation, the highest oil output rate and the least replaceable parts, each time the amount of extract is less (1-15 kg / times), time is short (8-12 minutes / time). It is a professional equipment for high oil seeds, such as sesame, peanut, walnuts, almonds, pine nut, tea seeds, etc.

Hydraulic Oil press Working Features

Hydraulic oil press operation, the processing of raw materials from the hopper into the pressure chamber. Under the action of the screw thread rotation, the material is gradually pushed from the feeding end to the cake end, and the volume of each section in the pressing chamber is gradually reduced. Because the screw thread continuously into the blank pressing chamber, such resistance push product pressure, compressed material embryo, the oil squeezed out.

 

Prior to the use of hydraulic oil press, the first should be ready for all auxiliary equipment and containers, check and adjust the tightness of the transmission belt. Then start the motor, make the machine running 15min or so, check the speed of the screw shaft, general speed should be around 33d/min. When you want to pay attention to the gear box gear meshing and the sound is normal, the bearing parts and the motor is normal. Oil press operation, motor current should be about 3A. If the current is too high, should immediately stop check, adjust and then boot. After the normal load, ready about 50kg of rapeseed or soybeans and then put into the hopper. Note: the feed should not be too fast at the beginning of the press, Otherwise, the pressure inside the chamber increases suddenly, Screw shaft does not move, causing pressing chamber blocked, even the cage is broken, the occurrence of major accidents. Therefore, the beginning of compression, the feed should be evenly and slowly into the hopper, so that oil press running. So repeatedly, for 3h ~ 4h  above, the press temperature gradually increased, and even smoke (which is normal). When the press is pressed, the temperature of the chamber is low, so that the handle can be moved slowly, and the handle on the screw rod can be enlarged to increase the thickness of the cake, at the same time, the water content of the raw material is increased, the temperature of the pressing chamber is raised to about 90℃, and the cake thickness can be adjusted to a value of 1.5 to 2.5mm after the oil press is in normal operation, then tighten the fastening nut.

After the normal operation of the hydraulic oil press, the oil content of high oil is mostly concentrated in the row and the front row. About 60% of the total oil output is in the row, and the former is about 30%; The end of the discharge of oil drops is very few, not a line, color is very clear. Two or three times can be repeatedly pressed rapeseed oil or soya bean juice, during which can be squeezed oil containing more evenly mixed material in the embryo. The material should be kept uniform, avoid too much or less, otherwise it will affect the life and oil extraction rate. During the operation of the oil pump to check the cake, and control the moisture content of raw materials. Normal out of the cake should be flaky, by pressing the screw shaft is a smooth side, the other side has a lot of hair. If the cake is loose and weak, or out of the cake is not formed, the color is deep, with a pinch of hand into pieces, which means that the raw material has too little water; If the cake is weak, into a large shape, or the oil bubble increased, it means the water is too much. Under normal circumstances, no residue or little slag exhausting, in a row at the slag, such as slag flakes that were more water, less water then slag powder. In addition, it can be seen from the changes in the location of the oil into the water is suitable, When the water pressure is too high or too low, the oil position is moved backwards.

Press Range of Hydraulic Press and Advantages

Hot pressed oil:sesame, flax, peanuts, wheat germ, corn germ, etc;

Cold pressed oil:pine nuts, almond, olive, walnut kernel, camellia seed, macadamia nuts, etc.

Spices and herbs:wild pepper, mustard seed, purple perilla, etc.

Good oil:Pure physical press, high oil yield, cold pressing process does not produce temperature, does not destroy the organic components of oil, good oil, less impurities, high cake value, a wide range of applications.

Easy operation, high efficiency：Mechanical and electrical integration design, low failure rate, high degree of automation, from the loading to the cake can be completed within 8 minutes, beautiful appearance, simple operation (one person can operate more than one.)

Note of Using Hydraulic Oil Press

1.External power supply must be solid, the layout should be reasonable and safe;

2.When the machine is started up or oil is pressed, the top plate must be completely closed. The top plate should be fully opened when the cake is out;

3.When the equipment is found in the work, please check the shutdown, see the hydraulic system and the motor drive fixed screws are loose, the pipeline is leaking;

4.At the end of the day, please clean the barrel and prevent oil residue, blocking oil seam;

5.Press out the end of the cake when the plunger is not too high to prevent the hydraulic oil out;

6.Add the specified brand of hydraulic oil, the timing of the hydraulic oil filter, clean the tank, found that hydraulic oil should be promptly added;

7.If the pressure gauge is found to be abnormal, stop the operation in time and inform the staff to repair it;

8.Before the test machine, the user must be in accordance with the provisions of the local power grid reliable grounding or zero line;

9.During the operation of the equipment, do not open the electrical cabinet or fuel tank.
