PURPOSE:To obtain a feed without giving off a bad smell even on presercvation for a long period, by pouring brewed lees into an oil, replaceng water and an alcohol with the oil under specific reduced pressure conditions, and taking the lees from the oil. CONSTITUTION:Brewed lees, e.g. SAKE lees, beer cake, low-class distilled spirit less or whisky lees, are poured into an oil, e.g. an animal oil, fish oil or vegetable oil, preheated at 90 deg.C or above, and heated with the heated oil as a heating medium under stirring and reducing the pressure. In the initial process for reducing the pressure, dehydration is carried out under low reduced pressure conditions. The vacuum degree is then increased to replace water and alcohol in the brewed lees with the oil. The resultant brewed lees after the dehydration and removal of the alcohol is taken out and pressed in a press, e.g. a screw press, or centrifuged, etc. to separate the oil. The separated lees are then pulverized, and used directly or mixed with an optional feed to give a feed. |
