The object of the present invention is to provide a method for manufacturing solid milk having suitable hardness for practical use by manufacturing powdered milk having good compaction moldability.In the manufacturing method of solid milk of the present invention, powdered milk for manufacturing solid milk is produced (S100), and then solid milk is produced by produced powdered milk. This manufacturing process (S100) comprises a gas dispersal process (S112) and a spray drying process (S114). In the gas dispersal process (S112), a prescribed gas is dispersed into liquid milk which is an ingredient of the powdered milk. In the spray drying process (S114), the liquid milk having a dispersed prescribed gas is sprayed, and the sprayed liquid milk is dried. By performing these processes, powdered milk is obtained. Solid milk is manufactured by solidifying the powdered milk.本發明的目的是提供一種藉由製造具有良好壓實成型性的奶粉製造具有適於實務使用的合適硬度之固形乳的方法。在本發明固形乳的製造方法中，生產用於製造固形乳的奶粉，隨後由所生產的奶粉生產固形乳。奶粉製造過程包括氣體分散過程和噴霧乾燥過程。在氣體分散過程中，指定氣體分散至作為奶粉原料的液態乳中。在噴霧乾燥過程，噴霧具有所分散之指定氣體的液態乳，並乾燥所噴霧的液態乳。藉由執行此等過程而獲得奶粉。固形乳係藉由固化奶粉而製造。
