The raw materials for making fish oil preparations are commonly found in mackerel, herring, tuna, flounder, salmon, cod liver, whale blubber, seal oil, etc. A small amount of vitamin E is usually added to play an antioxidant role. The fish oil separated by pressing still contains a small amount of protein, mucus, phospholipids, FFA, pigments and odor components, which is called crude fish oil. It cannot be eaten directly or used as a raw material for medicine.

Then, the two movable plates 20 and the two lower pressing blocks 22 are rotated along with the two movable shafts 19 respectively until the two lower pressing blocks 22 correspond to the positions of the two limiting holes 21, and then the two screw rods 17 are rotated by the two hand wheels, thereby driving the two lifting plates 18 to move downward, and at the same time driving the two movable shafts 19, the two movable plates 20 and the two lower pressing blocks 22 to move downward, thereby enabling the two lower pressing blocks 22 to enter the inside of the two limiting holes 21 respectively and squeeze the perforated disc 15 downward, and at the same time, the first filter screen cylinder 6, the second filter screen cylinder 7 and the third filter screen cylinder 8 can be squeezed and fixed by the squeezing cover 13.
