Pressed to open new oil press to use

 First, the purchase of oil press
A good oil press oil processing enables the user removed a lot of trouble . The selected model can be processed rapeseed , soybean , peanut , cottonseed, oil seed and other granular . First look at the time of purchase whether the machine's exterior paint evenly , check the machine 's parts are missing , and then turn the large pulley by hand , making it more than several turns to check whether there is extra virgin bore iron and other foreign matter , whether stuck phenomenon , while paying attention to the gear box gear is normal.
Second, oil press installed correctly
Before installation, respond to newly acquired peanut oil press machine to conduct a thorough clean-up. Out of the spindle , shed on the pressing cage, screw with emery cloth to squeeze the outer surface , an inner surface and screw feeder polished smooth . Greasing of all lubricating parts , gearbox lubricants are added , the varieties and grades shall conform to the requirements of the manual . After sanding smooth round row , in the installed position must be arranged according to the original , can not be misplaced , because the rows are arranged round the location and order of performance for oil extraction great relationship . Round row after installed with compression nut pressed , pressed discs in oil extraction degree to squirm when appropriate. Oil press after the above treatment, can be fixed with anchor bolts in the foundation. In the installation, the motor pulley to be aligned pulleys and oil press , moderately , rotation in the right direction , the tightness of the belt should be adjusted appropriately .
Third, the use of oil press
Use oil press , you should first prepare all assistive devices and containers, check and adjust belt tightness . Then start the motor , so that the machine empty running about 15min to check pressing screw shaft speed . Average speed should be around in 33dmin . Note idling gears meshing gear box and the sound is normal, the bearing parts and motors are normal. Oil press idling, the motor current should be about 3A . If current is too high , you should immediately stop checks, adjustments and then boot .
Load is normal, around 50kg ready rapeseed or soy , ready hopper . Note: when you start squeezing the feed can not be too fast, otherwise the sudden increase in pressure within the pressing chamber , pressing screw shaft can not rotate , causing blockage pressing chamber , and even squeeze cage rupture, a major accident . Thus begins the compression , the feed should be evenly slowly put into the hopper , the oil press for running-in . So repeatedly , sustained more than 3 ~ 4h , the oil press temperature gradually increased , and even take smoke ( this is normal ) . Start squeezing when pressing chamber temperature low, slow twist , withered section stud on the handle to increase the thickness of the cake , while increasing billet juice into the water until the pressing chamber temperature . Rose to about 90 ℃ , oil press after the normal operation , the thickness of the cake can be adjusted to 1.5 ~ 2.5mm, and tighten the fastening nut .
Oil press machine normal operation, the high oil content of fuel oil are mostly concentrated in the former group of rows and rows of round place . Department of rows out of fuel oil accounts for about 60% of the total , the front row at the group round about 30% ; while the end of the discharged oil is small, not a line into droplets , oil color is very clear . Can be repeated two or three times virgin rapeseed or soy Youzha do , during which more diesel oil can be uniformly doped materials embryo crushing , cutting to remain uniform , avoid erratic , otherwise it will affect the life of the oil press and oil yield .
During operation should always check the oil press cake out of the situation and control the moisture billet is neither too high nor too low. Normally the cake should be flaky, by pressing screw shaft side smooth , the other side has a lot of hair pattern. If the cake loose weakness, or the cake shapeless, darker color , hand pinch Serve fragments , indicating little billet water ; such as the cake soft, National Cheng Kung University flake, or increase the oil bubble , Minga is said too much water . Under normal circumstances, between the rows of circles with little or no slag slag , slag in row at the bar , such as the description of the slag was fine flake more water , the powder residue indicates less water . In addition, changes in position to see the oil squeezed out of water is appropriate, when squeezed into the water is too high or too low , the oil positions are backward .
Fourth, to meet the requirements of pretreatment process
Parison into juice , it must pass pretreatment process , pre- press machine will directly affect the quality of work and the oil yield . Different pre-treatment step of oil have different requirements, but including the following items:
1 . Cleanup. Oil entering the processing plants contain some impurities ( sand , gravel , iron , etc. ) , if not carefully cleaning , oil press internal parts will accelerate wear and reduce oil yield , and even cause malfunctions and accidents. Its supporting equipment: cleaning sieve , stone machine, magnetic separator , etc.
2 . Sheller . For shelled oil, should be peeled before pressing, this can increase the production capacity and oil yield . Its supporting equipment: Sheller , separation sieve , separating machines.
3 . Broken. Some oils can be squeezed into the monolith , but after crushing, flaking and then squeezed , can significantly improve the oil yield . Its supporting equipment: crushers, flaking machines.
4 . Steaming and roasting . Steaming and roasting is to improve the oil yield important part , a common approach is to first oil wetting , and then dried by frying pan , so that the requirements to process oil into virgin moisture and temperature, and its supporting equipment: steaming wok , Broiling pan .
