What are the common faults of peanut pressing machines 2024-07-23 16:19:03 internet

The oil press refers to the machine that uses the role of mechanical external forces to improve the temperature and activate the oil molecules, and the oil squeezed out of the oil from the oil.As the name implies, the peanut oil press is a oil press with peanuts as the oil presses.As one of the main oils, peanuts are used as raw materials by many communities. Therefore, the scientific use of peanut oil press has become important.The following will introduce the installation instructions of the peanut oil machine and the common failure of peanut oil press for reference.
Peanut oil machine principle
Peanuts are native to South America and are an important high -oil separation with shell soft oil.The peanut content is 65%-75%, the oil output rate is 40%-48%, and the protein contains 25%-31%. It is one of the most important rod oil and protein resources.Peanuts are a high -oil crop. The internal oil is surrounded by spherical or granular shapes in the cells. In the process of being squeezed by the outside world, this layer of film and cell wall are broken together. Peanut oilIt flows out of the crack; during the squeezing process, the oil in the peanuts is squeezed out, the peanuts become crispy and hard, and the original elasticity is lost; while the peanuts have more fiber, after applying pressure, and peanuts with peanuts after applying pressure, and peanuts with peanuts.The surface is separated, so that the peanuts are easy to fall off; in the process of squeezing, the peanuts suffer from the pressure rather than the shear force, so there is no crushed benevolent phenomenon and it is easy to restore the original state.
Instructions for installation of peanut oil oil machines
1. Before use, you must read the instruction manual carefully to be familiar with the performance characteristics and operation methods of the machine.
2. Before turning on, a comprehensive inspection must be performed. The fasteners must not be loose. The handle rotates flexibly. Rotate the belt wheel with the hand. Each operating part should be normal, and there must be no abnormal noise. Then add 30#engine oil to the reducer.
3. Remove the lock -up nut and rotate the screw in counterclockwise (adjust the handle to rotate the time clockwise, the gap between the cake becomes narrow, adjust the handle to rotate smoothly, and the gap of the cake becomes wide) to make the cone surface of the squeeze tightened the cake ring.The cone surface, then rotate the screw (3-5 laps) clockwise, and then tighten the nut to prepare to boot.
4. The machine is connected to the three -phase and four -line power supply. After the power supply is connected, the main axis should be rotated counterclockwise. Regardless of any situation, the machine must have a good grounding device, otherwise it cannot be turned on.
5. Adjust the temperature control meter
The temperature required to be pressed is 120 ℃ -180 ℃ (depending on the oil) to open the heating switch to the host heating position, heating and heating the machine. At this timeWhen the set temperature is set, and the red light is turned off, the temperature of the machine is automatically controlled and maintained at the set temperature. When the temperature is low in winter, the heating switch is turned on to all the heating position of the host, so that the temperature of the oil dish is increased, which is convenient for oil to facilitate the oil plateLeave the liquid.
6. Press the main motor button (open the host to the positive position) to start operation. The rotation direction should be rotated counterclockwise.
7. After the new oil machine is installed, a 4-8 hour grind is made. The method is to use the squeezed oil cake to slowly feed from the fighting fight, repeatedly squeeze it back, so that the squeezing is polished. Remember to start grinding.The material is directly poured into the material, and it is advisable to grab it with your hand to prevent the screw stuck from death.If the feeding is too fierce, an abnormal noise or a threaded stuck appears in the squeeze bore, and you should stop immediately, eliminate obstruction, or re -assemble and then start the grinding. Forcibly forcibly trailer.
8. When squeezing normally, keep the feed evenly. Do not too much or air -proof.At this time, the machine load is normal, runs smoothly, and the sound is rhythmic.The cake is smooth, the low -pressure section is basically residue, and there are a small amount of oil residue in the high pressure section, but the proportion of the residue in the oil is not more than 10%.The cover is discharged from the smoke pipe.Squeeze the hot cakes to spread out in time, do not rush to pile or transport it, otherwise it will produce natural phenomena.When the continuous working time is long and the machine temperature is too high, the cooling measures such as a fan of electric fans should be taken.
9. When the oil flowing out of the oil flowing into the oil filter, press the vacuum pump button, the vacuum pump begins to run, the air in the oil filter is pulled out, the internal pressure is formed in the oil filter barrel, and the oil above the oil is naturally pumped into the filter filter.The oil device, and the oil residue is isolated on the filter cloth. After the pressure is squeezed, after the oil is pumped, turn on the valve on the oil filter, stop the vacuum pump operation, form a dry residue on the filter cloth, scrape it with a spatula, and you can use a spatula to remove it.The bottom valve in the pure oil device in the oil filter is released.
10. Torter.Stop the feed before stopping, and then put a small amount of cake crumbs. After the remaining ingredients are exhausted, the cake mouth will no longer be out of the cake to stop.After stopping, the screw is adjusted out of the clockwise 1-3 lap to disconnect the power.
Common faults of peanut oil oil machines
The oil press consists of two parts: hydraulic and squeeze machine. Its common faults and exclusion methods are as follows.
1. Insufficient hydraulic pump pressure
the reason is:
① There are stains or poor contact with the oil -out door; ② The inlet and outbound oil valves on the squeeze machine are in poor contact with the valve seat or the non -tightness causes the oil return; ③ The gap between the small piston and the pump body is too large.The corresponding exclusion method is: ① grind after removing and washing to make it close; ② Gourge the oil valve stuffed and valve seats on the piercing press, so that it is tight or tightened; ③ replace the new pump.
2. The hydraulic pump cannot be pumped on the oil
the reason is:
① The oil filtration network is blocked; ② The oil is used for a long time, and the sediment is attached to the input door to make the throttle dense; ③ the oil in the fuel tank is too thick or the sky is cubic; ④ insufficient oil in the fuel tank; ⑤ hydraulic pressureThe pump is not vacuum.The corresponding method of exclusion is: ① cleaning the oil filtering net; ② replace the new oil or release the old oil; filter and clean the oil living door, and grind it to make it close;Add a sufficient amount of oil to the fuel tank; ⑤ pull out the small piston, inject the oil and press it.
3. The pressure gauge pointer cannot be maintained, and the rapid decrease
the reason is:
① The safety valve is not sealed; ② Poor contact with the oil stuff and steel balls in and out of the oil valve; ③ The oil pipe joints and the hydraulic cylinder puff and the hydraulic cylinder have not been tightened; ④ The three -way oil return valve is inaccurate with the steel ball.The corresponding exclusion method is: ① grinding safety valve to make it close; ② grind the inlet and out of the oil valve to be tightly fit; ③ Tighten the oil pipe joints and hydraulic cylinder snail;
4. Rock rod push up
the reason is:
① Poor contact with the oil ball with the steel ball; ② the spring head is separated from the steel ball.The corresponding elimination method is: ① grind the oil valve and change the new steel ball; ② expand the spring head.
5.
the reason is:
① The steaming temperature of the oil is not suitable, the temperature of the ingredients is too low, and the water content of the cake is too high;The corresponding method of exclusion is: ① Adopt the appropriate steaming direction to increase the material temperature above 85 ° C, and the water content is less than 7%; ② pay attention to the thickness of the cake when making cakes;Reduce pressure.
6. The oil is leaked from the gap between the hydraulic cylinder and the piston
the reason is:
① The mouth of the leather bowl is incorrectly installed; ② the leather bowl is damaged.The method of exclusion is: reinstall the leather bowl and replace the new leather bowl.
7 Security valve failure
The reason is: ① The oil is not clean and the dirt is attached to the surface; ② the spring loses the elasticity; ③ the adjustment of the screw is not loose to the prescribed pressure;The corresponding exclusion method is: ① Disassembling and cleaning, such as valve port and valve needle damage should be grinded; ② replace the spring; ③ re -adjust the screw to make the pressure reach 40MPa; ④ re -grind the valveEssence
