A deacidification device for deacidification process of rice bran oil

Abstract

The invention discloses a deacidification device used in the deacidification process of rice bran oil. The oil mist nozzle comprises a nozzle body, a first ring wall, a second ring wall, an outlet, a conical bottom, and a conical column. It is characterized in that : The left side of the second ring wall is provided with a pressure plate for closing the left end of the second ring wall, the side of the inner periphery of the nozzle body close to the outlet is provided with a conical bottom, the conical bottom and the second ring wall , The first swirl chamber is formed between the pressure plates, the second swirl chamber is formed between the conical bottom and the outlet, the left side of the conical bottom is provided with a conical column, and the outer periphery of the conical column is provided with a swirl structure , the second ring wall is provided with a plurality of first radial through holes distributed along the circumferential direction, and the tapered bottom is provided with a plurality of second radial through holes distributed along the circumferential direction. The oil mist nozzle of the present invention can increase the atomization pressure through the design of the spiral swirl wheel and the swirl plate, can significantly improve the atomization effect of the oil mist, and the atomization particle size is finer and the atomization is more uniform.

Description

technical field [0001] The invention relates to the technical field of rice bran oil deacidification / deodorization process, in particular to a deacidification device used for the deacidification process of rice bran oil. Background technique [0002] Rice bran oil (also known as rice germ oil, rice oil) is stored between rice husks and embryos. After rice processing, it exists in the by-products of rice bran and rice germs, which are extracted and then refined. Rice oil is rich in oryzanol, phytosterols, and natural vitamin E, among which the content of oryzanol reaches 3000ppm-7000ppm, which is extremely low in other vegetable oils. Oryzanol can reduce total cholesterol and blood lipids, and has unique effects of regulating nerves, calming sleep, and effectively relieving fatigue. In the refining and deacidification process of rice bran oil, how to retain oryzanol as much as possible is a problem that needs to be solved. For example, prior art CN102492546A discloses a meth...

Problems solved by technology

[0003] However, the existing oil mist nozzles have the problems of insufficient atomization and insufficient uniformity of atomization, and further design and improvement are needed to improve the atomization effect of oil mist
