Abstract: 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.

Abstract: A solid milk may include 0.5 wt % to 4 wt % of free fat, wherein a total fat content, including the free fat, is 5 wt % or higher. The solid milk may have a porosity of 30% to 50% and a solubility of 5 seconds to 180 seconds, where the solubility is defined as a time required to dissolve the solid milk completely when the solid milk is placed in 100 mL of water at 50° C. and shaken at a rate of 1.5 cycles/sec and an amplitude of 30 cm. The solid milk may have a hardness of 30 N to 300 N, where the hardness is defined as a force causing fracture when a load is applied in a direction in which a surface area of a fracture surface of a sample becomes minimal.

Abstract: A solid milk combining sufficient strength with sufficient solubility can be obtained basically by compacting and molding only powdered milk as an ingredient under a condition where porosity and free fat content thereof are controlled within fixed ranges and then humidifying and drying to produce a solid milk with a porosity of 30% to 50%. The solid milk has a moisture content of 1 wt % to 4 wt %.

Abstract: A method for manufacturing solid milk includes a gas dispersal process (S112) for dispersing a prescribed gas into liquid milk; a spray drying process (S114) for obtaining powdered milk by spraying the liquid milk after the gas dispersal process (S112), and drying the sprayed liquid milk; a compaction molding process (S130) for obtaining a solidified compaction molded body of powdered milk produced by compacting powdered milk after the gas dispersal process (S112) and the spray drying process (S114); in which the powdered milk obtained by performing the gas dispersal process (S112) and the spray drying process (S114) is bulkier than the powdered milk obtained without the gas dispersal process (S112).

Abstract: A powder compression molding machine is configured such that a plurality of lower and upper punches 61, 41 are allowed to enter a plurality of through-die holes 31 provided in first and second molding die sections 32, 33 of a slide plate 3 in a compression molding zone 21 to compressively mold powder and the slide plate 3 is slid to push out compacts downward and collect them in compact discharge zones 22a, 22b. Even when powder is compressively molded at a low compression force into solids having high porosity, compacts can satisfactorily be molded and collected without crumblingness, the compacts having sufficient high porosity and being dissolvable in water or the like.

Abstract: The present invention suggests a method for treating a liquid food, which is suitable for efficiently and effectively decreasing the dissolved oxygen concentration in liquid foods having high foaming property and low defoaming property such as skim milk. The dissolved oxygen concentration of the liquid food is decreased by putting the liquid food into a decompression vessel while heating the liquid food to a temperature higher than or equal to the saturation temperature (boiling point) of the liquid food under the decompression atmosphere in the decompression vessel, or putting the liquid food into a decompression vessel while depressurizing the decompression vessel to a pressure lower than or equal to the saturation vapor pressure of the liquid food at the temperature of the liquid food.
