Solid milk and method for manufacture thereof

Abstract

A method for manufacturing solid milk includes a gas dispersal process (S 112 ) for dispersing a prescribed gas into liquid milk; a spray drying process (S 114 ) for obtaining powdered milk by spraying the liquid milk after the gas dispersal process (S 112 ), and drying the sprayed liquid milk; a compaction molding process (S 130 ) for obtaining a solidified compaction molded body of powdered milk produced by compacting powdered milk after the gas dispersal process (S 112 ) and the spray drying process (S 114 ); in which the powdered milk obtained by performing the gas dispersal process (S 112 ) and the spray drying process (S 114 ) is bulkier than the powdered milk obtained without the gas dispersal process (S 112 ).
