Application of roots water ring vacuum unit in physical refining of rice bran oil
The roots water ring vacuum unit is used for the physical refining of rice bran oil, with low operating power, low protection, sensitive and inconvenient device, which increases production profit and obtains good economic benefit. The production of waste oil, to achieve the national standard four – level refined rice bran oil requirements. This unit is suitable for use in small-scale physical refining production line. Physical refining requires that the vacuum absolute pressure is less than or equal to 200Pa, so in the grease production year, the water ring vacuum pump, the soda water series vacuum pump can not meet the requirements, the normal use of water vapor injection vacuum pump. However, the operating profit of water vapor injection vacuum pump is high, it needs to be equipped with medium and small sized steam boiler, which is not applicable to some medium oil plants.
Root vacuum pump is widely used in vacuum distillation, vacuum volatilization and dewatering crystallization in chemical industry, and it is seldom used in oil industry. We have equipped root water ring vacuum unit in the rice bran oil physical refining deacidification production line, increased the production profit, produced the new national standard four – level refined rice bran oil. This unit is suitable for use in small-scale physical refining production line.
Roots type vacuum pump is a non – internal compression of the air – filled variable – capacity vacuum pump. It USES two figure-eight rotors to curl up in the pump housing to create the effect of inhalation and exhaust. It makes it impossible to discharge the gas into the atmosphere indirectly, and it needs to be used in tandem with the former vacuum pump. The gas is pumped into the atmosphere through the front stage vacuum pump. work, is pumped gas from the air inlet into the spinor and pump body, then a spinor and pump body to separate gas and air inlet, was separated from the gas, in the spinor always fills the air in them, were sent vent.
The roots water ring vacuum unit can be used for physical refining and deacidification of rice bran oil on a small scale. It has a sensitive device, low operating power and low protection. The waste oil produced can meet the requirements of the national standard four-level refining rice bran oil, which is applicable to the small-scale physical refining production line.
