Detailed Description
As shown in figure 1, the ultrasonic reflux extraction device for camellia oil comprises a first-stage extraction tank 1, a second-stage extraction tank 2 and an evaporation tank 3, wherein the first-stage extraction tank and the second-stage extraction tank are respectively provided with a stirrer 4, and the bottoms of the first-stage extraction tank and the second-stage extraction tank are respectively provided with a filter screen 5; the top of the first-stage extraction tank is provided with a first feed inlet 6 and a first liquid inlet 7, the first-stage extraction tank is provided with a first discharge outlet 8 along the upper part of the filter screen, and a first suction filtration port 9 is arranged along the lower part of the filter screen; the top of the secondary extraction tank is provided with a second feed inlet 10 and a second liquid inlet 11, the secondary extraction tank is provided with a second discharge outlet 12 along the upper part of the filter screen, and a second suction filtration port 13 is arranged along the lower part of the filter screen; the second feed inlet 10 is communicated with the first discharge outlet 8 through a feed delivery pipe; a solvent return pipe 14 of the evaporation tank is communicated with a second liquid inlet 11, a second suction filtration port 13 is communicated with a first liquid inlet 7, and a first suction filtration port 9 is communicated with the evaporation tank 3; the first-stage extraction tank is provided with a heating jacket 15, and the second-stage extraction tank is provided with an ultrasonic generator 16.
In the structure, the first suction filtration port and the second suction filtration port are driven by the vacuum pump to lift air and filter. The conveying pipe is powered by a conveying pump.
When drawing, the tea-oil camellia seed that grinds gets into the one-level by first feed inlet earlier and draws the jar, pour into the solvent into by first inlet, heat the leaching to the tea-oil camellia seed, after the extraction a period, take out most solvent by first suction filtration mouth, get into the evaporating pot, separation tea-seed oil and solvent, the solvent gets into the back flow after the condensation, rethread second inlet pours into the second grade and draws the jar, and simultaneously, the tea-seed that has the surplus solvent in the one-level jar of drawing is mixed in the jar input second grade and is drawn the jar, carry out the ultrasonic wave in the second grade jar of drawing and draw.
Since the solvent extracts the oil by concentration diffusion, i.e. the difference between the oil concentration in the solvent and the oil concentration in the raw material. This scheme design second grade draws jar, and the grease concentration reduces in the raw materials after the jar draws through the first grade, gets into the second grade and draws the jar after, because separated the dissolved grease through the solvent of evaporating pot backward flow, consequently can keep with the concentration difference of grease in the raw materials, consequently can guarantee the extraction efficiency of second grade extraction stage. In the traditional scheme, in the later stage of solvent extraction, the concentration of oil in the solvent rises, the concentration of oil in the raw material falls, and the concentration difference in the later stage is reduced, so that the extraction efficiency is low, and even if the time is prolonged or ultrasonic-assisted extraction is adopted, the extraction efficiency is difficult to be greatly improved.
After the scheme is adopted, compared with the traditional scheme, the extraction time can be shortened by 20%, and the oil yield can be improved by 10%.
As a further improvement of the scheme, a heat exchanger 17 is connected between the second suction filtration port and the first liquid inlet, and the first suction filtration port is connected with the heat exchanger and then connected with the evaporation tank. The solvent temperature that first suction filtration mouth came out is higher, and the solvent temperature that the second suction filtration mouth came out is lower, and after the heat transfer, the solvent temperature that the second suction filtration mouth came out rose, and reentrant one-level extraction jar can reduce the heat-up time, further improves extraction efficiency.
As a specific selection of the heat exchanger in the improved scheme, the heat exchanger is a tubular heat exchanger, and the tubular heat exchanger has the advantages of high heat exchange efficiency and stable operation.
