Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fish oil extraction, in particular to a separation device for fish oil extraction. Background Art
[0002] Fish oil is extracted primarily from fatty fish (such as anchovies and sardines), processed marine fish scraps (such as cod and salmon), and freshwater fish scraps (such as tilapia and basa). Furthermore, cod liver oil is extracted primarily from shark liver, mackerel liver, and large yellow croaker liver. The fish oil extraction process involves a separator to separate the fish oil from water and other substances.
[0003] Existing fish oil extraction and separation devices usually use a pressing method to extract fish oil. Steamed fish is placed in a press to squeeze out the fish oil. During the process of squeezing the fish meat to extract the oil, there is no device to assist in squeezing and separating the fish oil. As a result, the separation rate of the fish oil from the fish is slow, which reduces the extraction efficiency.
[0004] Moreover, there is still water in the fish oil after pressing, and the existing oil-water separation usually uses evaporation to evaporate the water. During the evaporation process, the fish oil and water need to be steamed at high temperature for a long time. Multiple steamings will accelerate the reaction of unsaturated fatty acids in the fish oil with oxygen in the air, leading to oxidation and reducing the nutritional value of the fish oil. Therefore, it is necessary to propose a separation device for fish oil extraction to solve the above problems. Utility Model Content
