The course of work of the present invention is: timer is connected motor 20, starting automatically.Rotation along with motor.Four weights 16, begin to rotate.At centrifugal action lower heavy punch 16, by connecting rod 15, the tapered valve 11 in garden, upwards lift, valve is closed automatically.Infuser begins to the wet dregs of rice of rotary drum discharging.The wet dregs of rice fall into behind the rotary drum under centrifugal action solvent through mesh 7, be thrown toward housing 2.Solvent is run into housing 2 backs and is sunk to falling in the cyclic solvent collector groove 13, through communicating pipe 23.Flow into solvent and accumulate jar.Squeezing into infuser in 24 leaches again.Timer disconnects drive motors 20 stalls after 2～3 minutes, and weight 16 falls, and garden awl valve 11 falls and opens automatically.The wet dregs of rice through drying through the garden tapered valve 11 discharge and ° send the evapo-separated machine oven dry.So move in circles.

In the prior art.Because the wet dregs of rice are directly sent into exsolution drying the evapo-separated machine after infuser is discharged; Consume a large amount of heat energy on the one hand.Solvent is dried by the fire in the wet on the other hand dregs of rice.Solute in the solvent is adsorbed in the residual dregs of rice again.The raising that dregs of rice Residual oil is relative.

Employing the present invention can throw away a part of solvent in the wet dregs of rice and solute can improve oil yield about 0.3%.Only consume a part of electric energy (is example with the soybean) 10,000 tons of oil plants of every processing and can overcharge back about 4.8 ten thousand jin in soya-bean oil.Can increase about 50,000 yuan of profits more and save evapo-separated machine heat energy more than 30%.10,000 tons of oil plants of every processing.Can economize on coal more than 100 tons.And can reduce the residual molten content of the dregs of rice.

Carry out the dregs of beans of low temperature desolventizing except that possessing above advantage to preserving soybean protein.Also will help low temperature desolventizing.

The simple declaration of accompanying drawing: this Figure of description Fig. 1, the three-dimensional slightly diagrammatic sketch of practical application vertical section of the present invention.The plane that cooperates of Fig. 2 rotating shaft spline sample emboss pit and garden tapered valve spline sample emboss pit.The engage side view of the tapered valve in Fig. 3 rotating shaft garden, weight

The automatic input of the wet dregs of rice, the isolation with the wet dregs of rice after the separated from solvent is a core of the present invention.According to characteristics of the present invention: rotary drum 10, rotating speed should be on per minute 3000 right side of turning left.Rotating speed low humidity dregs of rice light specific gravity, the centrifugation factor is little, to the many large-scale infusers of each discharge also be unfavorable for being subjected to centrifugal force controlled the tapered valve 11 in garden, folding.Drive motors 20, adopting timer to control start-up time should be before the each discharge of infuser.Should be able to reach rated speed during the infuser discharge.Rotate again after the infuser discharge finishes and stopped automatically in 2-3 minute.The cone angle of bottom of the drum should be between 80 °-90 °, in order to avoid discharge is not smooth.The volume of rotary drum will have surplus.In order to avoid the wet dregs of rice are thrown out of during drum rotating.Mesh 7 is decided on material properties.

The tapered valve 11 in garden should account for 1/2nd to 2/3rds of rotary drum 10.Tapering is between 80 °-90 °.Should fall during unlatching about 15-20 centimetre in order to avoid discharge is not smooth.When closing and the contact-making surface of rotary drum want tight, prevent that the wet dregs of rice from entering by dishing out in the slit in the molten collector groove 13 of ring-type.

Parallel the getting final product in lower edge of the interior edge of cyclic solvent collector groove 13 and the tapered valve 11 in garden.

Weight 16, be directly to control circular cone valve 11, folding.The size decision of the size of weight centrifugal force and hammerhead jib length acceleration of gravity according to the maximum weight of material in infuser one lattice and when falling.The tapered valve 11 in garden is not washed open in the time of should be able to guaranteeing infuser maximum discharge.Four weights can increase weight quantity in the time of can not satisfying.The tapered valve 11 in garden is closed the angle that should have between back weight and the horizontal plane about 5 °.

The fixed pivot up and down 1.17 of centrifugal device rotating shaft 8, enough intensity should be arranged.Bearing should seal or the axle envelope.Weight falls at present, and fixed pivot should not collide with weight.
