Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fish meal preparation, in particular to an oil-water separation device for fish meal preparation. Background Art
[0002] Fish meal is a powder obtained by crushing, cooking, separating and drying one or more fish meats. It is rich in protein and is often used as a raw material for fish or other poultry feed. In addition to protein, fish meat, which is used as a raw material, also contains oil. In the preparation process of fish meal, fish oil and protein water need to be separated so as to dry fish meal from the protein water. At present, the commonly used oil-water separation methods mostly adopt the form of filter membranes. After the mixed liquid flows through the filter membrane, the oil will be filtered, and the protein water can pass through the filter membrane, thereby achieving oil-water separation. The ordinary filtering method is inefficient and it takes a long time for the protein water to pass through the filter membrane. Therefore, some processing plants have also introduced centrifugal separation equipment to separate protein water and oil by centrifugation. However, the filter membrane used in the centrifugal process is basically only a single layer. After multiple oil-water separations, the equipment needs to be suspended to clean or replace the internal filter screen, resulting in the equipment needing to be shut down for a long time, unable to separate oil and water, and delaying the processing of fish meal. Utility Model Content
