0.1Mpa, starts heat-conducting oil furnace simultaneously and starts to warm up；When oil temperature is raised to more than 130 DEG C, opens live (open) steam, start cold simultaneously
But water circulation system, closes deodorizing tank Inlet and outlet water valve, opens cooler water-inflow and drain valve on vacuum line；Control live (open) steam
Amount, must not make oil droplet be splashed to tank top；Continue to use heat-conducting oil heating simultaneously, until tank temperature rise to 180 DEG C about；Keep
This temperature, continues evacuation, and vacuum maintains -0.01Mpa；It is raised to 180 DEG C of beginning timing from temperature, deodorization time 6-8 is little
When；After deodorising process terminates, claw the unburned coal cinder in heat-conducting oil furnace, open cooling water turnover valve cooling deodorised oil,
After oil temperature drops to less than 70 DEG C, break deodorizing tank vacuum, with oil pump through accurate filter filtration after toward freezing oil tank buy oil into
Row freezing dewaxing.
8. the method for purification Fructus Hippophae skin residual oil as claimed in claim 1 is it is characterised in that described freezing dewaxing, including with
Lower step：Crystallize growing the grain, filtration and melt cured；
Described crystallization growing the grain process operations：Start freezing unit, open freezing unit, by ethanol coolant be refrigerated to -10 DEG C with
Under stand-by；Crystallization maturator fill deep fat after, record tank in oil temperature, if oil temperature is more than 70 DEG C, open coolant supply valve to
It is passed through coolant in maturator, first oil temperature is down to 70 DEG C, then according to requiring cooling rate to oil cooling in tank, open simultaneously and stir
Mix, 10 turns per minute, and carry out itemized record；If cooling rate is too fast, should take the circumstances into consideration to turn down coolant supply valve opening degree；Instead
It, open big；Require cooling slow, do not allow rapid cooling：" actual temperature " should try one's best close to " requiring cooling temperature "；Insulation
Stage should be fixed time and is passed through coolant into maturator, the no big change of keeping temperature；Temperature-fall period should often be patrolled freezing unit
Working condition, notes abnormalities and should process in time；Every crystallization maturator oiling corresponds to every batch deodorised oil, is forbidden to intersect oiling；
If finding, growing the grain situation is poor should again melt cured recrystallization growing the grain for a certain crystallization；
Filter progress operates：Clean out dewaxing filter, filter cloth is balanced suitable, do not allow filter cloth to have Fold, and will
Row is into a line for filter plate left and right edges；After inspection is errorless, prepare oil strain；Open the good fuel-displaced valve of maturator of growing the grain, opened
Filter pump terminal valve and return valve, filter pump outlet valve guides filter；Start filter pump to oil filter fuel feeding；Slow-action is opened
Open oil filter oil inlet valve, open degree is between 1/3--1/2；Then adjust filter pump and import and export reflux inlet, make pump discharge pressure
Power controls in 0.3Mpa；After all fuel-displaced water nozzles of oil filter have oil out after, observe the fuel-displaced situation of water nozzle；Fuel-displaced should be
Limpid, if finding to have the fuel-displaced muddiness of indivedual mouths should close this fuel-displaced water nozzle immediately；After 5-10 minute, with clean beaker from fuel-displaced
Mouth connects oily half cup, will contain rusting cup and shine light compared with oil reservoir in benefit observation cup；If finding suspended crystal in oil, should keep
Observe, until the transparent no suspended crystal of oil reservoir shows that in oil, cured crystalline substance is completely cleared, now should turn down oil inlet valve, and rapidly
Roily oil in oil-containing groove is discharged in roily oil case, then oil-containing groove is guided edible vegetable oil mouth, and inlet valve is recovered former open position, enter
Enter normal filtration；During normal filtration, it is still to observe the fuel-displaced situation of profit mouth at any time, find there is fuel-displaced muddiness, water nozzle should stand
Close；During filtration, inlet pressure can gradually rise, if having a large amount of permeability phenomenon between this stage filter plate and filter cloth, can
Suitably filter plate compression hydraulic system is opened and filter plate is compressed again；If inlet pressure rises to 0.4Mpa, can stop into
Oil, closes inlet valve, stops filter pump；By the filter oil-containing groove oil-out stopping filtering guiding roily oil mouth, and open oil-in
Place's compressed air valve is blown into compressed air into filter to carry out blowing cake；Starting to blow tolerance during cake should be less, now should be by oil-feed
The all fuel-displaced water nozzle that filter cuts out is opened, and first presses out unfiltered oil substantial amounts of in filter chamber, is then gradually opened compression
Air door, by Residual oil blow pressure in cured cake out；Whne the basic oil-free of fuel-displaced water nozzle out when can close compressed air, Ran Houjin
Row melts cured operation；By the complete liquidation of bright for the overflow connecing in cured groove oil to roily oil oil-containing groove；Simultaneously also will be clear for excess oil in oil-containing groove
Reason is clean；Periodically filtration roily oil is squeezed into and recrystallize after refrigerated cylinder；Squeeze into product tank by filtering edible vegetable oil；
Melt cured process operations：First boiler temperature be raised to more than 95 DEG C stand-by；After dewaxing filter end of operation, open
Enter hot water valve, start hot water circulating pump, carry out molten cured, molten cured during it is ensured that certain hot water temperature, treat all of go out cured
Mouth all no cured outflow when, open air cock, carry out blowback from oil-out, whne all of go out La Kou all no cured outflows when, can recognize
For molten cured finish, close hot water valve and heat-exchanger pump, it is normal for open cold water starting dewaxing filter is lowered the temperature until filter
Temperature；Carry out the filtration of subsequent cycle；The cured timely barrelling flowed out transports workshop.
