ABSTRACT:
A batch process for making fish meal products, which does not pollute the environment, is described. All operations are conducted in equipment not open to the atmosphere and the liquids and gases produced are treated to remove odors. Fish is precooked in a cooker and the steam and vapors are conveyed to scrubbers where the foul-smelling gases are rendered innocuous. The pre-cooked fish meat in the cooker is pressed to removed press liquid which is treated to recover oil, fish meat and stickwater. The pressed fish meat in the cooker is then dried and removed as a product. The stickwater is evaporated under vacuum to recover dry water-soluble fish materials as a product and the overhead vapors are chemically treated to remove odors.
