Description

A kind of rice bran oil positive/negative-pressure combination exsolution apparatus

Technical field

The utility model belongs to fat and oil processing equipment technical field, and it is de- to relate more specifically to a kind of rice bran oil positive/negative-pressure combination Dissolving device.

Background technique

Rice oil is also known as rice bran oil or rice embryo oil, is to be obtained by rice bran using solvent extraction and the technique deep processing of physical refining , be agricultural product auxiliary product deep processed product, the nutrition such as oleic acid, linoleic acid and phytosterol and oryzanol rich at Point, the genuine piece and paddy gold being known as in edible oil.

However, extract and refining Rice oil needs solvent, using being recycled under the hot conditions of negative-pressure vacuum to solvent, Obtain the Rice oil of high-purity；However needing to maintain high negative pressure state using high negative pressure suction filtration, energy consumption is higher, and if negative It presses through height and will lead to grease and be also extracted, lead to the loss of material and be unfavorable for applying for solvent, how negative pressure is too low to lead Cause have a small amount of dissolvent residual in grease.

Summary of the invention

To solve the above problems, overcome the deficiencies in the prior art, the utility model provides that a kind of separative efficiency is high and energy Low rice bran oil positive/negative-pressure combination exsolution apparatus is consumed, can be effectively solved asking for dissolvent residual and solvent loss in tradeoff grease Topic.

The utility model solve above-mentioned technical problem the specific technical proposal is: the rice bran oil positive/negative-pressure combination precipitation Device, including cyclone separator and U-tube, the cyclone separator include solvent inlet, heavy out and light phase export, spy Sign is that the cyclone separator includes cyclone separator I and cyclone separator II, the heavy out of the cyclone separator I with The solvent inlet of cyclone separator II is connected by U-tube, and pressure is arranged to 0.03Mpa, the rotation in the cyclone separator I Pressure in stream separator II is arranged to -0.03Mpa, the height of the U-tube be greater than 7m, the cyclone separator I it is molten Agent import is connected with solvent-laden rice bran oil, and the temperature of solvent-laden rice bran oil is 100 DEG C, the density of the solution in the U-tube For 0.85-0.95g/cm3.

Further, the difference in height of the solvent inlet of the heavy out and cyclone separator II of the cyclone separator I For 0-10cm.

Further, the solvent boiling point in the cyclone separator and U-tube is lower than 100 DEG C.

The beneficial effects of the utility model are: two cyclone separators for being arranged to positive/negative-pressure are cleverly utilized in the present apparatus The U-tube for cooperating preset height is controlled without peripheral hardware water pump and valve, had not only been realized the effect of gravity flow but also had been guaranteed the effect of fluid-tight； The effect of fluid-tight avoid grease rapidly enter negative pressure cyclone separator cause positive pressure cyclone separator fail, so as to cause negative pressure Cyclone separator light phase export pressure is excessive, greatly reduces separative efficiency；The heavy out and eddy flow of the cyclone separator I The difference in height of the solvent inlet of separator II is 0-10cm；It ensure that the stability of gravity flow；The eddy flow for being arranged to positive pressure point After solvent in grease is carried out initial gross separation from device, under the effect effect of fluid-tight, negative pressure cyclone separator is slowly entered, negative Remaining solvent is separated from grease under the action of pressure.

Detailed description of the invention:

Attached drawing 1 is the utility model structure diagram；In attached drawing:

1. light phase export, 2. cyclone separators II, 3. heavy outs, 4. solvent inlets, 5. cyclone separators I, 6. U-tube.

Specific embodiment:

To keep the purposes, technical schemes and advantages of the utility model implementation clearer, 1 more comprehensively with reference to the drawings Ground description.In the description to the utility model, it is to be understood that term " center ", "upper", "lower", "left", "right", The orientation or positional relationship of the instructions such as " rear ", " lower-left ", " upper right ", "outside" is to be based on the orientation or positional relationship shown in the drawings, It is merely for convenience of describing the present invention and simplifying the description, rather than the device or element of indication or suggestion meaning must have Specific orientation is constructed and operated in a specific orientation, therefore should not be understood as the limitation to scope of protection of the utility model.This Outside, term " first ", " second ", " third " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.

Specific embodiment of the present utility model: the rice bran oil positive/negative-pressure combination exsolution apparatus, including cyclonic separation Device and U-tube 6, the cyclone separator include solvent inlet 4, heavy out 3 and light phase export 1, it is characterised in that the rotation Stream separator includes cyclone separator I 5 and cyclone separator II 2, the heavy out 3 and cyclonic separation of the cyclone separator I 5 The solvent inlet 4 of device II 2 is connected by U-tube 6, and pressure is arranged to 0.03Mpa, the eddy flow point in the cyclone separator I 5 It is arranged to -0.03Mpa from the pressure in device II 2, the height of the U-tube 6 is greater than 7m, the solvent of the cyclone separator I 5 Import 4 is connected with solvent-laden rice bran oil, and the temperature of solvent-laden rice bran oil is 100 DEG C, the density of the solution in the U-tube 6 For 0.85-0.95g/cm3.

Further, the height of the solvent inlet 4 of the heavy out 3 and cyclone separator II 2 of the cyclone separator I 5 Degree difference is 0-10cm.

It should be noted that the utility model is a kind of rice bran oil positive/negative-pressure combination exsolution apparatus, when specific works,

1. the grease containing solvent is heated to 100 DEG C, squeezed by the solvent inlet 4 of cyclone separator I 5, keeps eddy flow The pressure of separator I 5 is 0.03Mpa, and most solvent is flowed out after gasifying in the high temperature environment by light phase export 1；Density is The grease containing a small amount of solvent of 0.85/cm3 enters U-tube 6 by the heavy out 3 of cyclone separator I 5；

2. another outlet of U-tube 6 is connected by pipeline with the solvent inlet 4 of cyclone separator II 2, cyclonic separation Negative pressure is taken out in device II 2 to -0.03Mpa, the grease containing a small amount of solvent is pumped into U-tube 6, at this time due under the action of negative pressure, A small amount of solvent gasification forms air column in U-tube 6, and air column is isolated under the fluid-tight barrier of fluid column with cyclone separator I 5； And cyclone separator II 2 is slowly entered under the action of pressure difference, it is flowed out, is sloughed molten by the light phase export 1 of cyclone separator II 2 The grease of agent is flowed out by the heavy out 3 of cyclone separator II 2；

3. working principle therein are as follows: the pressure of cyclone separator I 5 is 0.03Mpa, takes out negative pressure in cyclone separator II 2 To -0.03Mpa, the grease density containing a small amount of solvent is 0.85/cm3, then according to the pass of pressure and density and grease pillar height degree Known to system: 0.06Mpa can lead to the oil column height that the grease that grease density is 0.85/cm3 generates 7.06 meters, at this point, if U-shaped The height of pipe 6 is lower than 7.06 meters, then grease directly can quickly suck cyclone separator II 2 by air pressure, so as to cause cyclonic separation Device I 5 loses separating effect, and all solvents can flow out under negative pressure state by the light phase export 1 of cyclone separator II 2, Pressure is excessive and has a large amount of dissolvent residual；Therefore, the height of U-tube is that can avoid the generation of the above problem greater than 7m.
