Description

Technical Field

[0001] The utility model relates to the technical field of peony seed oil production, and more specifically, to a peony seed oil dewaxing device. Background Art

[0002] Peony seed oil, also known as peony oil, is a woody nut plant oil extracted from peony seeds. It is made from peony kernels through pressing, crude oil filtration, decolorization, deodorization, dewaxing, precision filtration and other processes. The purpose of dewaxing is to ensure the freezing stability and transparency of the refined oil; the general dewaxing process is to heat the peony seed oil first, so that the wax that has been precipitated is completely dissolved in the oil, and the oil that has been cooled to a certain temperature is further cooled in the crystallization tank at a certain cooling rate. During the cooling process, the wax crystallizes and precipitates, and then the oil with precipitated wax is filtered, generally using a bag filter or a plate and frame filter. In the crystallization process, in order to ensure that the collision between the precipitated wax molecules is increased and the wax-containing oil is cooled evenly, it is necessary to stir appropriately. But the speed should not be too fast, otherwise it will break the crystallized particles, which is not conducive to crystallization.

[0024] Example 1

[0025] A peony seed oil dewaxing device, its structure is as follows Figure 1-3As shown, it includes: a crystallization tank 1 with a top cover 11, a cooling mechanism 2 for cooling the crystallization tank 1, a support frame 3 for supporting the crystallization tank 1 and the cooling mechanism 2, a driving mechanism 4 arranged above the top cover 11, a stirring mechanism 5 connected to the driving mechanism 4, and a feeding pipe 6 and a discharging pipe 7 connected to the crystallization tank 1 and arranged at the upper end and the lower end thereof, wherein the stirring mechanism 5 includes: a rotating shaft 51 connected to the driving mechanism 4, a stirring blade I 52 fixed to the upper half of the rotating shaft 51, and a stirring blade II 53 fixed to the lower half of the rotating shaft 51;

[0026] The stirring blades I 52 and II 53 are arranged perpendicular to the rotating shaft 51 and inclined to the horizontal plane;

[0027] The stirring blades I 52 and II 53 have inclination angles opposite to the horizontal plane.

[0028] In actual application, the rotating shaft 51 passes through the bearing arranged on the top cover 11 and extends downward into the crystallizer 1; the upper half of the rotating shaft 51 is provided with three stirring blades I52 at the same height, and the lower half of the rotating shaft 51 is fixed with three stirring blades II53 at the same height; each stirring blade I52 is arranged obliquely downward along the rotation direction of the rotating shaft 51, so that when the rotating shaft 51 rotates, the peony seed oil in the upper half of the crystallizer 1 rotates downward at the center, and rotates upward when close to the inner wall of the crystallizer 1; each stirring blade II53 is arranged obliquely upward along the rotation direction of the rotating shaft 51, so that When the shaft 51 rotates, the liquid in the lower half of the crystallizer 1 rotates and flows upward at the center, and rotates and flows downward when close to the inner wall of the crystallizer 1; the peony seed oil in the upper and lower parts of the crystallizer 1 moves in different directions and is more likely to cross-flow with each other, so that the wax molecules therein collide with each other and accelerate the crystallization speed; the top cover 11 is detachably connected to the crystallizer 1 by bolts 111, and a boss is provided on the lower surface of the top cover 11 to cooperate with the opening along the top of the crystallizer 1, which is convenient for positioning and installation of the top cover 11, and a sealing ring is provided at the opening along the top of the crystallizer 1 to seal the opening of the crystallizer 1.

[0029] Working principle: First, the peony seed oil enters the crystallization tank 1 from the feed pipe 6; secondly, the peony seed oil in the crystallization tank 1 is slowly cooled to 5-10°C by the cooling mechanism 2, and the peony seed oil is kept at this temperature for a period of time to crystallize the wax. During the cooling and crystallization process, the driving mechanism 4 drives the stirring mechanism 5 to rotate slowly, so that the wax molecules in the peony seed oil collide with each other, the crystallization speed is accelerated, and the peony seed oil is cooled more evenly; finally, the peony seed oil after cooling and crystallization is discharged from the discharge pipe 7.

[0030] By arranging stirring blades I 52 and II 53 with inclination angles opposite to the horizontal plane on the same rotating shaft 51, the wax molecules in the peony seed oil in the crystallization tank 1 can collide with each other better, thereby accelerating the crystallization speed, making the peony seed oil cool more evenly, and only one stirring mechanism 5 connected to the top cover 11 is required for stirring, which facilitates the maintenance and cleaning of the stirring mechanism 5 of the device and improves work efficiency.

[0031] Example 2

[0033] The cooling pipe 22 is arranged in a spiral shape around the outer wall of the crystallization tank 1 .

[0034] Working principle: the coolant in the cooling pipe 22 enters the water pump from one end, is pushed into the refrigerator for cooling through the water pump, and the cooled coolant flows into the cooling pipe 22 from the other end of the cooling pipe 22 to cool the peony seed oil in the crystallizer 1, and finally the coolant flows back to the refrigerator through the water pump, so that the coolant circulates and cools the crystallizer 1; the spiral cooling pipe 22 surrounding the outer wall of the crystallizer 1 and the circulating cooling structure make the cooling effect better, and because the cooling pipe 22 is arranged on the outside of the crystallizer 1 and does not contact the peony seed oil, it can avoid wax crystallization on the surface of the cooling pipe, affecting the cooling and crystallization effects, and increasing the cleaning work.

[0038] In practical applications, the width of the flexible silicone layer close to the inner wall of the crystallization tank 1 is 1-5 mm.

[0039] Working principle: During the dewaxing process of peony seed oil, the stirring mechanism 5 stirs the peony seed oil inside the crystallizer 1 while cleaning the inner wall of the crystallizer 1 to improve the stability of the device; in the process of cooling and dewaxing, it is prevented that wax crystals aggregate and crystallize on the inner wall of the crystallizer, resulting in the wax body remaining on the inner wall of the crystallizer after the peony seed oil is discharged, affecting the cooling and dewaxing effect of the crystallizer 1 when it is used next time, and affecting the use of the device.
