Hydraulic press, also known as hydraulic sesame oil machine, is now used in many places to crush Sesame, walnut and other high-grade oils. Hydraulic press belongs to the static oil production, the oil rate relative to the spiral press is low, the power consumption is small, the equipment is many and the area is large. However, the mechanism oil of liquid pressing oil has the advantages of simple structure and power saving, it can be applied to some scattered oil (such as rice bran, wild oil), and the need to maintain special flavor or nutrition of oil (such as cocoa beans, olive oil, sesame seeds, etc.) of the grinding slurry. In addition, it can be used for the separation of the press of the solid fat or wax bran.
Working principle of Hydraulic Press:
Hydraulic oil machine is to use hydraulic fluid pressure through the pump, the machine installed a temperature control device, Hydraulic Oil Press so that oil in high pressure and high temperature state of the extraction machinery. According to the driving power source of the oil pump, Hydraulic Oil Press there are two kinds of manual and electric;
Hydraulic sesame oil machine is the simplest operation in mechanical oil, the highest oil output rate, the replacement of the least vulnerable parts of a press, is currently a substitute for small grinding sesame oil manual operation of the most advanced equipment, because each squeeze less (1-15 kg/time), short time (8-12 minutes/time), particularly suitable for the current squeeze is sold. Pressure press is to stir up the fuel directly into the barrel of oil, the rapid manufacture of 100% pure balm, people witnessed the production process, buy the rest assured, Hydraulic Oil Press eat the peace of mind! The machine is dedicated to the crushing of sesame seeds, peanuts, walnut kernels, almonds, pine seeds, tea seeds and other high oil crops professional equipment.
Key points in the use of hydraulic press: When the hydraulic press runs, the material embryo from the hopper enters the crushing chamber. Under the action of screw thread rotation, Hydraulic Oil Press the feeding end is gradually pushed toward the cake end. The volume of each section of the cylinder is gradually reduced, and the screw thread continuously pushes the feed embryo into the pressing chamber, which pushes the product pressure, compresses the material embryo and squeezes out the oil.
Before using the hydraulic press, all the auxiliaries and containers should be prepared, and the tightness of the belt should be checked and adjusted. Then start the motor, so that the machine to air around 15min, check the speed of the screw shaft. General speed should be around 33dmin. Idling should pay attention to gear box gear meshing and sound is normal, the bearing parts and motor is normal. When the oil press idling, Hydraulic Oil Press the motor current should be around 3A. If the current is too high, should immediately stop inspection, adjust and then boot. No-load Normal, prepare 50kg or so of rapeseed or soybeans, ready to put into the hopper. Note: Starting to press the feed can not be too fast, or the pressure inside the cylinder suddenly increased, squeezing screw shaft, resulting in a squeeze, or even the crushing cage rupture, a major accident occurred. Therefore, when the beginning of compression, Hydraulic Oil Press feed should be evenly into the hopper, so that the oil press to run together. So many times, continue to 3~4h above, so that the temperature of the press gradually rise, even the smoke (this is the normal phenomenon). Start squeezing when the chamber temperature is low, you can slowly twist, the handle on the Spiral column, increase the cake thickness, while increasing the moisture into the feed, to be pressed to the chamber temperature. Up to 90 ℃ or so, Hydraulic Oil Press the normal operation of the oil press, the cake thickness can be adjusted to 1. 5~2. 5mm and tighten the fastening nut.
After the normal operation of hydraulic press, the oil with high oil content mostly concentrates in the row and the front group's round row. The oil in the row is about 60% of the total oil output, the former group is about 30% in the round row, and the end of the oil is very small, and the oil color is very clear. Hydraulic Oil Press Repeatedly squeeze two or three times can be rapeseed or soy oil squeeze out, during this period can be oily oil more evenly mixed with people
The material embryo is squeezed. When the material to keep evenly, should not be more or less, otherwise it will affect the life of the press and oil yield. In the course of operation to constantly check the cake situation, and control the moisture content of the embryo is not too high or low. Normal out of the cake should be flaky, Hydraulic Oil Press on the side of the squeezing screw shaft smooth, the other side has a lot of fur lines. such as out of the cake loose, or out of shape, the color of the deep, with the hands of a pinch that is a fragment, which indicates that the embryo material and water too little, such as the cake weak, into a large-scale, or oil foam increase, then the water too much. Under normal circumstances, the round row between the slag or very little slag, in the row out of slag, Hydraulic Oil Press such as the slag is a fine sheet of water, the powder slag shows that less water. In addition, the oil position changes can be seen whether the water is appropriate, when the water is too high or too low, the oil position is shifted backwards.
Squeeze range of hydraulic press oil: sesame, flax, peanut, wheat germ, corn germ, etc. cold-pressed oil: pine seeds, almonds, olives, walnut kernels, camellia seeds, macadamia nuts and other spices and Chinese medicine: pepper, mustard seeds, basil and other oil good: pure physical press, high rate of production, cold pressing process does not produce temperature, do not damage the organic components of oil, good oily, containing less impurities, Hydraulic Oil Press high cake value, wide application. Easy to operate, high efficiency: mechatronics design, low failure rate, high degree of automation, from the loading of the cake can be completed within 8 minutes, the appearance of exquisite, simple operation (one person can operate multiple units. ）
