Canola oil press machine processing process
1, hot pressing: canola a cleanup - frying seeds a pressing - filtration - finished canola oil;
Operating instructions: canola selection of Specification 30 mesh / inch screen for screening, so that the rapeseed contains less than 0.5% impurities, and then in the softening, softening rapeseed moisture content of 9% or so, and then steam frying, steaming and frying so that the temperature of the oil to 110-120 degrees, the moisture content of l-1.5% or so, you can go into the oil press for pressing. Such as the use of cylinder frying pan, rapeseed can be directly into the cylinder frying pan into the flat bottom frying pan can be cleaned to remove impurities. However, add 2-3% of water when frying seeds, frying to 110-120 degrees, that is, can be pressed out of the pan. Hot pressing can use the following methods to determine whether the rapeseed is well fried. With two boards rubbed rapeseed, if the shell kernel separation, kernel into a dark yellow color is appropriate, if the kernel into powder is too dry, if the shell and kernel are not separated is too wet.
2, cold pressing: rapeseed - cleaning - pressing - filtration - finished canola oil;
Operating instructions: cold pressing when the rapeseed will be cleaned up to remove impurities, there is no need to frying pan for frying material, cold pressing of rapeseed moisture content will directly affect the oil efficiency. Oil efficiency, so determine the wet and dry oil is very critical, generally into the press before the water content of rapeseed control in 5-8%, with the earth method to determine the water content of rapeseed high and low, you can use your fingernails to squeeze the rapeseed if there is a ringing sound, and divided into two pieces, there is oil extrusion for the water content of the right, if into the powdered part of the water content is less too dry, if into a flat shape, then the water content of the water content of the high and too wet.
Problems that are likely to occur in the pressing process: rapeseed oil content up to 33-40% or so, the general hot press according to the instructions of the operating manual operation will not appear abnormal phenomena, if the cold press due to improper operation or the oil content of water is not suitable for rapeseed oil press body temperature is not good, there will be running slag, back to the oil or feed phenomena such as smooth, then you can refer to the cold press of peanut kernels. The cold press of peanut kernel can be referred to for treatment.
The oil press machine should be adjusted before the start of the press screw shaft and cake clearance, so that the press screw shaft forward against the cake mouth, and then backward 2 to 3 turns, so that the gap is controlled in the 0.5 to 1.0 mm, so that the oil yield can be guaranteed, which is the most important thing that customers want to see.
Before the oil into the press, you should keep the oil press idling for ten minutes to confirm that there is no abnormality, and then the oil is evenly introduced to make the press chamber grinding heat. The wet and dry of the oil needs to be judged by the operator, and adjust the body temperature accordingly, the press chamber temperature reaches 80 degrees Celsius can start pressing.
Pressing: should slowly adjust the thickness of the oil cake, different varieties of oil, the number of presses are different, the thickness of the cake is generally controlled between 0.25-0.5 mm. When the work is considered satisfactory, you can trigger the hand lever to lock the adjusting nut, will increase the feed to the normal amount of feed.
When you find that there is a blockage in the cake outlet, you should stop feeding, pull out the feed regulator plate, remove the material stored in the feed outlet, and then slowly withdraw the main shaft to remove the blockage in the press chamber. When pressing sesame, peanut and other oil materials with high oil yield, it can be pressed several times until the oil materials are pressed clean.
Working with a wooden stick to pound the feed opening to prevent clogging of the mouth, and strive to feed evenly, and timely removal of residue leakage, recovery of dregs can be put back into the hopper to continue to press. Before stopping the machine to stop feeding new material, but the need to press all the residual cake in the chamber discharge, before increasing the gap between the cake, so that the excess oil residue in the chamber discharge.
After the shutdown of the oil press maintenance work is also very critical, should be extracted from the press screw shaft, clean up the press chamber and the residue in the gap, to ensure that the press chamber is clean. Work about 3 months, should be cleaned drive shaft of the two bushings, the bearings will be filled with butter, adjust the concentricity of the press screw shaft and the press chamber, the press screw shaft and cake ring wear serious should be replaced; press bar single-sided wear up to 2 mm can be changed to use the face of the oil press both sides are worn out to change the press bar.
How to choose rapeseed oil press
1, whether intelligent control? Whether frying, oil extraction, oil filtration integration?
If you are still choosing the traditional old-fashioned manually operated oil press, you are out. Three-in-one intelligent commercial oil presses have long overcome the old-style oil presses of various criticisms, such as: the technical requirements to be. Frying, oil extraction, oil filtering separate operation, labor intensity and so on. One key operation, is so cow.
2, whether it can be automatically cleaned?
Can you imagine the old oil press is a lifetime? Because of the cast iron parts, can not be cleaned, a wash full of rust, so the machine squeezed out of the oil, you dare to eat? Three-in-one intelligent commercial oil presses choose aluminum alloy and stainless steel, automatic cleaning, out of the real oil is assured.
3, is it suitable for a variety of materials? Whether small quantities can also be squeezed?
Previously, to open an oil mill or oil factory, at least peanut oil press, sesame oil press, rapeseed oil press, etc., because each kind of oil press can only squeeze a kind of material, 50 pounds of each press, which invariably lost a lot of customers, a family a month where you need so much oil? Now it is not the same, three-in-one intelligent commercial oil presses minutes into the material, just a matter of pressing the button, the small amount is no longer a problem, the size of the customer a handful of profit is still a problem?
4, whether 220v electricity? Is the volume of lightweight, free to move?
Old oil presses are almost always 380v, cast iron construction, stupid and bulky. To buy a machine but also reconnected to the electricity, the amount of work, maybe the cost is more expensive than the machine. If one day you want to move the machine, tell you, no way, if it is not too much trouble, looking for a moving company may be able to, the labor is not worth it. Three-in-one intelligent commercial oil press 220v home electricity, lightweight, move at will, where you want to extract oil where you want to go, only you can not think of, no can not go.
5. Does the oil come out clear? Does it need to be precipitated?
Clear oil or not decided to sell your products, precipitation or not decided to sell your time. Imagine the old-fashioned oil press out of the oil black, waiting for it to filter, waiting for it to precipitate, vegetables are cold, customers ran away. Now three-in-one intelligent commercial oil press out of the oil straight out of the supermarket to sell oil, the speed is also leveraged, how to choose, still need me to tell you?
6, can high temperature sterilization?
Yes, I'm right, high temperature. I've never heard of it, I think the old oil press press simply did not have this statement, but also high temperature sterilization, do not create bacteria is good. The so-called technological progress is like this, three-in-one intelligent commercial oil press can already high temperature sterilization, chuck kill everything.
