How much oil could be extracted from 50 kilograms of the rapeseed?

 

  In general, 50 kg of rapeseed will yield around 37 catties of oil while the yield of oil is around 40%, which is enough to make forty catties worth of oil. It is largely dependent on the quality of the rapeseed used and the grade of the equipment for oil pressing. In accordance with the standard of the nation the oil content of 1st Grade is is 40 percent, 2nd grade oil content 39 percent, 3rd Grade oil content 38 percent, 4th grade's oil content is 37% the 5th grade's oil content amount of oil is percent, the content of oil for grade 6 is percent, the oil content for the 7th grade is 34 percent while the content of oil for the grade 8 level is 33% percent.

 Improve the oil yield from rapeseed.

 Its oil production from rapeseeds is typically just 30 to 40 percent. Utilize the techniques below to increase the oil yield by 25 percent.

 1. Eliminate impurities. The rapeseed's sediment can absorb oils during the process, thus decreasing the yield of oil. So, any impurities like the rapeseed's sediment must be eliminated prior to processing.  seed oil presses for sale

 2. Manage the fire. In general, when you fry the rapeseeds in a pot, it's only out of the pan when all rapeseeds have been cooked. some rapeseeds may stay on the base of the pot and become burned in each batch. So, when the seeds are cooked to the point that they're mature and ready to be cooked, the stove on top should be opened, while the lower tuyere needs to be shut off to stop the flame. The method for doing this is to build an open slot that can be moved on the inside of the mouth of the stove, and then embed the movable iron plate. If a large fire is needed, lift the iron plate to close the mouth of the stove; If a low-fire is required, set the iron plate in place to shut off your air intake. oil refinery machine

 3. Enhance the equipment for oil pressing. If you are refitting the screw press to utilize the 95 type vertical shaft oil press the previous No. 6 screw press could be utilized instead in place of the no. 5 screw press. This could increase the internal pressure and cause the oil outlet to move back 8-10cm. By this alone, every 100kg of rapeseed could create 1-2kg of oil. cold press oil machine

 4. Press the hot substance. The molecules of oil are active at temperatures that are high. The temperature of rapeseed which has just been removed from the oven is 108 degrees, and you are able to squeeze more oil when it's still hot. It is therefore recommended to limit the quantity of fried seeds per pot between 40 and 50kg, so that it is press simultaneously at all the time to make sure that the hot material is being pressed. camellia seed oil

 5. A proper amount of bran in the right amount. The rapeseed is high in oil contentand slides quickly when pressurized into the press cylinder. Then, the rapeseed cake is released from the press before the oil has been squeezed. In this way, 5kg of grain bran may be mixed in the rapeseed for every 100kg, good rapeseed may mix with greater while bad rapeseed is mixed with lesser. The bran should be in good condition and free of any debris and the ash needs to be removed through the process of sieving. Bran addition can reduce the speed at which rapeseed slides which means it will help squeeze out more oil. The oily feet that appear after the oil has been mixed with the bran and squeezed between rapeseeds may also increase the yield of oil.
