The method is to introduce high-temperature steam or inert gas into the oil. After stirring, the free fatty acids are taken out by the steam or inert gas, and then separated by condensation. Compared with other separation methods, such as extraction, filtration and crystallization, its advantage is that it does not require the use of other solvents other than the system components.

[0025] The first aspect of the utility model provides a distiller for deacidification of fish oil, such as Figure 1 , Figure 3 , Figure 5 As shown, it comprises a base 1 and a distillation tank 2 arranged on the base 1, wherein a heating chamber and a distillation chamber are respectively arranged in the distillation tank 2, a plurality of heating tubes 3 are installed inside the heating chamber, a heat conducting plate 4 is fixedly installed between the heating chamber and the distillation chamber, a discharge pipe 5 is installed on the top of the distillation tank 2, a liquid inlet pipe 6 is also arranged at the side end of the distillation tank 2, and an air inlet pipe 7 is also arranged below the liquid inlet pipe 6;

[0026] A transverse stirring blade 8, wherein the transverse stirring blade 8 is rotatably installed in the distillation chamber through a driving assembly;

[0027] A lifting part 9, a guide post 10 is fixedly connected to the middle of the lifting part 9, the guide post 10 is slidably arranged on the heat conducting plate 4, and a tension spring 11 is connected between the guide post 10 and the lower end surface of the heat conducting plate 4;

[0028] The longitudinal stirring blade 12 is fixedly mounted on the lifting part 9 , and the longitudinal stirring blade 12 is placed above the heat conducting plate 4 , and the lower end of the transverse stirring blade 8 is intermittently in contact with the upper end of the lifting part 9 .

[0029] In this embodiment, the driving assembly includes a driving motor 13, a driving wheel 14 and a driven wheel 15. The driving motor 13 is installed on the top of the distillation tank 2 through a mounting frame, and the driving wheel 14 is installed on the output end of the driving motor 13. A rotating shaft 16 is also rotatably installed on the top of the distillation tank 2, and the driven wheel 15 is installed on the rotating shaft 16.

The transverse stirring blade 8 is installed at the lower end of the rotating frame 18.

[0030] In this embodiment, when in use, the fish oil to be deacidified enters from the liquid inlet pipe 6, and then high-temperature water vapor or inert gas is introduced into the distillation tank 2 through the air inlet pipe 7. At the same time, the driving motor 13 is started so that its output end drives the driving wheel 14 to rotate, and in turn drives the rotating frame 18 to rotate through the synchronous belt 17, the driven wheel 15 and the rotating shaft 16, and then drives the horizontal stirring blade 8 to stir the fish oil in the distillation chamber in a horizontal direction.

[0034] In this embodiment, if Figure 4 , Figure 5 As shown, a plurality of avoidance gaps are provided on the lifting part 9, and the avoidance gaps are used to prevent the lifting part 9 from having rigid contact with the heating tube 3 during the lifting process.

[0035] In addition, preferably, Figure 2 As shown, an observation window 20 is provided at the side end of the distillation tank 2 to facilitate observation of the fish oil level inside the distillation tank 2 and its mixing status with the high-temperature gas, so as to timely replenish high-temperature water vapor or inert gas and the fish oil to be deacidified.
