Description

Technical field:

[0001] The utility model relates to the technical field of vegetable oil deacidification tower equipment, in particular to an integrated deacidification tower device capable of producing ultra-high oryzanol rice oil. Background technology:

[0002] Oryzanol is a mixture of ferulic acid esters with triterpenoids as the main component, which has multiple physiological functions such as lowering blood lipids, lowering liver lipids, preventing lipid oxidation, and anti-oxidation.

[0003] Phytosterols are a type of unsaponifiable substance widely found in vegetable oils. Due to their anti-inflammatory, antioxidant, and periodontal bacterial growth inhibition effects, they are widely used in food, medicine, cosmetics, animal growth enhancers, and other fields.

[0004] Rice bran oil is extracted and refined from the rice bran and germ, a byproduct of rice processing. It is rich in various nutritionally active ingredients, such as oryzanol, phytosterols, vitamin E, squalene, and more. High oryzanol and phytosterol content is a key characteristic of rice bran oil. However, a sampling survey of rice bran oils currently on the market revealed that oryzanol and phytosterol content is generally labeled within the range of 3,000 ppm to 15,000 ppm, with a small number labeled at 18,000 ppm. No rice bran oils with higher oryzanol content have been found. With the promotion of oil and fat conservation and the integration of medicine and food, increasing the intake of medicinal ingredients such as oryzanol and phytosterols while maintaining a constant fat intake is a promising development.

[0005] However, most current methods are to produce high-oryzanol rice bran oil by optimizing the rice bran oil processing technology, and there are few solutions that can overcome the above problems and achieve the production of ultra-high-oryzanol rice bran oil by modifying the equipment. This urgently requires a solution that can further increase the oryzanol and phytosterol content in rice bran oil, produce ultra-high-oryzanol rice bran oil (oryzanol content ≥4%), break through the inherent oryzanol and phytosterol content limitations of crude rice bran oil, and is simple and easy to industrialize.

[0029] An annular distributor 16 is provided on the outer side of the upper end of the condensation hood 2, and the annular distributor 16 is connected to the outlet end of the circulating medium feed pipeline 18. The inlet end of the circulating medium feed pipeline 18, the constant temperature control valve 15, the pump 17, the air cooling tank 14, and the outlet end of the circulating medium discharge pipeline 19 are connected in sequence, and the inlet end of the circulating medium discharge pipeline 19 is connected to the circulating medium collecting tank 13; the extra-high-grain rice oil intermediate product collection tank II 11 is connected to the extra-high-grain rice oil intermediate product oil outlet pipeline 10, and the front end distributor 9 of the deacidification tower oil inlet pipeline 8 is placed at the lower part of the deflection mechanism and the upper part of the collector 22.

[0030] The baffle mechanism includes a baffle 6, which is placed on the upper part of the double-layer baffle 7. The baffle 6 is connected to the lower end of the discharge pipe 4 and the upper baffle 23 through fixed ribs 12 respectively.

[0031] The condensation cover 2 includes a conical main cover and an annular cover wall. The bottom end of the conical main cover is integrally connected to the annular cover wall, and the annular cover wall is placed outside the collector 22.

[0032] The condensation cover 2 is made of stainless steel.

[0034] The upper baffle 23 and the lower baffle 24 of the double-layer baffle 7 are spaced 2 cm apart from the condensation hood 2 .

[0035] The collector 22 is designed as an inverted cone-shaped collector with openings at the top and bottom.

[0036] The working principle of this utility model is as follows:

[0037] 1. The rice oil that has been degummed, dewaxed and bleached once enters the deacidification tower through the deacidification tower oil inlet pipeline 8. After being evenly distributed by the distributor 9, it interacts with direct steam from bottom to top under a high temperature of 255℃-260℃ and a vacuum with a residual pressure of ≤50pa, and the nutrients such as oryzanol and phytosterols with medium molecular weight and a small amount of large molecular weight rice oil heavy components are separated upwards along with the small molecular weight fatty acids.

[0038] 2. During the rising process, the light component bypasses the baffle mechanism and contacts the condensation cover 2 for condensation. The nutrients such as oryzanol and phytosterols that rise with the small-molecule fatty acids and heavy components such as a small amount of rice oil are cooled and liquefied along the condensation cover 2. The light component flows into the extra-high-gluten rice oil intermediate product collecting tank II 11, is collected into a temporary storage tank via the extra-high-gluten rice oil intermediate product oil outlet pipeline 10, and is subsequently decolorized, deodorized, and defatted to obtain the extra-high-gluten rice oil product. The extra-high-gluten rice oil in this patent refers to rice oil with an oryzanol content of ≥4%.

[0039] 3. The circulating medium used in this patent is preferably circulating rice oil. The cooled circulating rice oil (200°C) flows down the condensation hood 2 through the annular distributor 16 to keep the condensation hood 2 at the same temperature. The condensation hood 2 exchanges heat with the rising light component (about 260°C). After heat interaction in the deacidification tower, the nutrients such as oryzanol and phytosterols in the light component and a small amount of large molecular weight rice oil heavy components are separated and flow into the ultra-high-grain rice oil intermediate product collection tank II11 below, and finally enter the medium storage tank.

[0040] The circulating rice oil after heat exchange flows into the circulating medium collecting tank 13, enters the air cooling tank 14 through the circulating medium discharge pipeline 19, and is cooled to a preset temperature by the air coil, and then is pumped into the deacidification tower through the constant temperature control valve 15 by the pump 17. After being evenly distributed by the annular distributor 16, it flows downward along the condensation hood 2 to the circulating medium collecting tank 13, thereby condensing the material inside the condensation hood 2 at a constant temperature.

[0041] 4. When the light component rises, it will be forced to change its flow direction by the deflection mechanism, and the condensation cover 2 close to the surrounding area will move upward, thereby increasing the heat exchange area of ​​the condensation cover 2 and facilitating the collection of condensed rice oil.

[0042] The double-layered baffles 7 are designed to create a temperature difference between the upper baffles 23 and the lower baffles 24. The higher temperature of the lower baffles 24 does not affect the evaporation of light components, while the lower temperature of the upper baffles 23 does not affect the collection of condensed droplets. This creates a particularly large number of ultra-high-grain rice oil intermediate droplets at the fatty acid outlet, filler I 5. The ultra-high-grain rice oil intermediate produced here flows along fixed ribs 12 and baffles 6 to ultra-high-grain rice oil intermediate collection tank I. From there, it is collected via oil conduit 21 and then transferred to ultra-high-grain rice oil intermediate collection tank II 11.

[0043] The ultra-high oryzanol rice oil intermediate produced by the utility model can be processed into an ultra-high oryzanol rice oil finished product after subsequent processing. The oryzanol content can reach 4.8% and the phytosterol content can reach 3.9%, which is equivalent to the ultra-high oryzanol rice oil produced by adjusting the process.

[0044] It can be understood that the above specific description of the present invention is only used to illustrate the present invention and is not limited to the technical solutions described in the embodiments of the present invention. Ordinary technicians in this field should understand that the present invention can still be modified or replaced by equivalents to achieve the same technical effects; as long as the use requirements are met, they are within the scope of protection of the present invention.
