Description

Technical Field

[0001] This utility model relates to the technical field of deacidification equipment, and in particular to a low-temperature alkali refining and deacidification equipment for sea buckthorn fruit oil. Background Technology

[0002] Sea buckthorn fruit oil, a natural oil rich in unsaturated fatty acids, vitamins, and other active ingredients, owes its quality directly to the scientific nature of its deacidification process. Low-temperature alkali refining deacidification, which maximizes the retention of active ingredients, has become one of the core processes in the refining of sea buckthorn fruit oil. However, existing technologies still have many problems to be solved in practical applications. One issue is that the low-temperature control system of existing equipment is not well-designed, lacking an efficient structure that combines heat preservation and uniform cooling. This causes the temperature inside the tank to fluctuate easily due to external environmental influences, which not only disrupts the stability of the alkali refining reaction but also induces oxidation of heat-sensitive active ingredients in the sea buckthorn fruit oil. The process suffers from several problems: firstly, degradation, significant cold loss, and low energy efficiency, making it difficult to meet the refining requirements of high-quality sea buckthorn fruit oil; secondly, existing stirring mechanisms are mostly single-function designs, failing to achieve sufficient dispersion and efficient contact between the two phases, resulting in incomplete deacidification reaction; and thirdly, in traditional processes, soap residue separation, residual alkali washing, and oil drying are dispersed in multiple independent devices, making the materials prone to oxidation and deterioration during material transfer, which not only increases the equipment footprint and production operation complexity but also causes problems such as insufficient separation precision and uneven washing, affecting product quality stability and production efficiency.

[0019] Working Principle: Using this invention, firstly, the mounting holes 6 on the protective cavity 5 are aligned with the corresponding fixing holes 8 on the upper surface of the dissolving tank 1. Bolts 9 are then threaded into the mounting holes 6 and fixing holes 8 to securely install the protective cavity 5 on the upper surface of the dissolving tank 1. Subsequently, the low-temperature control system is activated. The vacuum insulation jacket 2, fitted onto the outer wall of the dissolving tank 1, forms a sealed, heat-insulating space. The spiral cooling pipes 4 within the jacket 3 circulate coolant, evenly conducting heat through the spirally distributed pipes to cool the interior of the dissolving tank 1. Simultaneously, the vacuum insulation jacket 2 prevents external heat intrusion, ensuring a stable low-temperature alkali refining environment within the dissolving tank 1, providing suitable temperature conditions for the deacidification reaction of sea buckthorn fruit oil. The rotating motor 13 inside the protective cavity 5... After the circuit is powered on, the rotating shaft 12 connected to its output end rotates within the shaft cavity 10 opened on the upper surface of the dissolving tank 1, thereby driving the shaft column 11 installed inside the dissolving tank 1 to rotate synchronously. The bottom of the shaft column 11 is fitted into the stabilizing ring 17 installed on the outer surface of the bottom of the static separation mesh tank 16. The stabilizing ring 17 provides bottom support for the shaft column 11 to prevent it from shifting during operation. After the sea buckthorn fruit oil to be deacidified and the alkali solution are put into the static separation mesh tank 16 inside the dissolving tank 1, the inclined stirring blades 14 fixedly connected to the outer wall of the shaft column 11 rotate with the shaft column 11, pushing the material in the static separation mesh tank 16 to form an overall circulation, avoiding local material stagnation. At the same time, the toothed elliptical blades 15 on the shaft column 11 rotate at high speed, generating a shearing effect on the material and dispersing the alkali solution into tiny droplets. The contact area between seabuckthorn fruit oil and alkali solution is significantly increased, promoting a thorough alkali refining and deacidification reaction. The mixture after the deacidification reaction first undergoes preliminary filtration through the mesh of a static separation tank 16, trapping large soap shavings. The pre-purified mixture then flows through the static separation tank 16 into the area between the upper inclined plate 20 and the lower inclined plate 21, which are fixedly connected within the dissolving tank 1. At this time, the shaft 11, through the fixed columns 19 evenly connected along the circumference, drives the centrifugal separation tank 18 at the bottom to rotate synchronously. During rotation, the centrifugal separation tank 18 generates centrifugal force, throwing small soap shavings remaining in the mixture against the inner wall of the tank and trapping them. The pure seabuckthorn fruit oil, after two separations, then passes through the mesh of the centrifugal separation tank 18 and flows along... The inclined surfaces of the upper inclined ring plate 20 and the lower inclined ring plate 21 flow downwards. After the pure sea buckthorn fruit oil enters the washing chamber 22 fixedly connected to the bottom of the lower inclined ring plate 21, deionized water is introduced through the annular water pipe 23 at the connection end between the washing chamber 22 and the lower inclined ring plate 21. The atomizing nozzles 24, which are evenly arranged along the circumference of the annular water pipe 23, spray atomized water evenly into the sea buckthorn fruit oil in the washing chamber 22 through the corresponding connection holes 25 on the upper surface of the washing chamber 22. The atomized water fully contacts the fruit oil to neutralize the residual alkali in the fruit oil. The mixture after washing is guided to the edge by the guide cone bottom 26 fixedly connected to the bottom inner side of the washing chamber 22. It is filtered by the outer ring screen 27 fixedly connected between the guide cone bottom 26 and the washing chamber 22 to intercept the water residue generated during washing.After the water residue is removed, the sea buckthorn fruit oil enters the drying and collecting chamber 28 located at the bottom of the washing chamber 22. After water removal is completed in the drying and collecting chamber 28, it is finally discharged from the outlet 7 fixedly connected to the outer wall of one side of the drying and collecting chamber 28, completing the entire low-temperature alkali refining and deacidification process of the sea buckthorn fruit oil.
