Abstract
Produce consolidating of vegetable oil at the use lixiviation process---in the liquid extraction process, also contain the solvent about 30% in the wet dregs of rice that material is discharged by infuser after extracting.Also contain a spot of solute in these solvents.
The present invention is the centrifugal device of a device in the automatic discharges material of energy of utilizing weight control of the wet bottom, dregs of rice exit of infuser.The wet dregs of rice are thrown out of through the centrifugal action solvent of this device.Through collecting, extract the oil yield that can improve oil plant.Save heat energy.
Description
Produce in the leaching process of vegetable oil at the use lixiviation process.Material is sent into infuser and is sprayed successively through solvent.Oil content successively decreases successively after the fresh solvent spray.Draining the wet dregs of rice is discharged by the infuser exhaust end.Send evapo-separated machine that solvent is taken off most oven dry and become the residual dregs of rice of finished product.
Owing to still contain solvent about 30% in the wet dregs of rice after infuser drains, also contain a spot of solute.After the wet dregs of rice are admitted to evapo-separated machine.Solvent is dried by the fire.Solute is adsorbed on the residual dregs of rice again.
The objective of the invention is to reduce the content of solvent from the wet dregs of rice that infuser is discharged.Contained solute also corresponding reduction can reduction dregs of rice Residual oil improves oil yield in the wet like this dregs of rice.Save the heat energy that is used to evaporate this part solvent in the evapo-separated machine.
Introduce the present invention in detail below in conjunction with Figure of description.
1, centrifugal device top fixed pivot.2, housing 3, ring flange.4, discharge funnel.5, rotary drum.6,9 rotary drums and rotating shaft fulcrum.7, mesh, 8, the centrifugal device rotating shaft.Confinement plate on the awl valve of 10 gardens.11, the tapered valve in garden.12, the spline sample emboss pit on the tapered door in rotating shaft and garden.13, cyclic solvent collector groove.14, confinement plate under the tapered valve in garden.15, connecting rod.16, weight.17, centrifugal device bottom fixed pivot.18, rotating shaft garden bevel gear.19, driving shaft garden bevel gear.20, drive motors.21, driving shaft.22, observation window and working hole.23, cyclic solvent collector groove and solvent are accumulated the communicating pipe of jar.24, solvent is accumulated jar.25, connecting rod and the tapered valve in garden is connected.26, connecting rod is connected with weight arm.27, weight arm and spline sample emboss pit be connected 28, edge in anti-the throwing.
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.
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.
Two garden bevel gears 18.19 should be installed sheath.Driving shaft 21, should install sheath and bearing.
Solvent is accumulated solvents in jars 24. and can be sneaked into fresh solvent and leach.The solute that contains about 2 ‰ of fresh solvent is little to leaching effect influence like this.Also can reduce the spray flux of fresh solvent, solvent be accumulated solvents in jars 24. squeeze into separately and immerse infuser and leach again.
Test method of the present invention:
Get from the wet dregs of rice exit of infuser 1 kilogram not drying drain the wet dregs of rice.Be divided into two parts.Portion is put into the per minute 3000 right centrifuge that turns left and is got rid of and took out oven dry in 2~3 minutes.The directly oven dry of another part.Chemically examine two parts of dregs of rice Residual oils in the residual dregs of rice respectively, relatively two results of laboratory test.
Action wants fast in the test, makes the wet contained solvent of the dregs of rice remain on 30% temperature as far as possible and remains on about 50 ℃ and ' otherwise can influence result of the test.
