Provided is a method for producing a compressed body of a powder capable of improving a hardness while suppressing a decrease in production efficiency of the compressed body of the powder. A compressed bodyof a powder is compression molded by compressing a powder supplied into die holesby a lower punchand an upper punch. In the compression molding, a first compression and a second compression following the first compression are performed. In the first compression, the compression is performed at a first compression speed, and in the second compression, the compression is performed at a second compression speed that is lower than the first compression speed.

Method for producing compressed body of powder

A solid food is a solid food having a solid form obtained by compression molding and hardening a food powder, in which a specific surface area voxel ratio of the solid food is configured such that an average value A from a surface of the solid food to a depth of 2 mm is smaller than an average value C from a depth of 4 mm from the surface of the solid food to a depth of 6 mm, and a rate of decrease (C−A)/C×100 of the specific surface area voxel ratio obtained by dividing a difference (C−A) between the average value C and the average value A by the average value C is 9.5% or less.

Solid food, compression-molded food powder product, solid milk, and compression-molded powdered milk product having reduced fracture stress

A method for producing a solid food having a solid form obtained by compression molding a food powder includes: compression molding the food powder to form a compression molded body of the food powder; and performing a hardening treatment on the compression molded body of the food powder, in which the hardening treatment includes placing the compression molded body of the food powder under an environment of a humidity of 100% RH or less and a temperature of higher than 100° C.

Method for producing solid food product, and method for producing solid milk including hardening treatment

A solid food is a solid food having a solid form obtained by compression molding a powder, in which in a case where a drop test in which the solid food is dropped onto a drop face is repeated until the solid food is broken, the number of times of dropping leading to breakage when a dropping energy density per unit fracture stress EF is 2×10[(J/m)/(N/m)] is 3 times or more, the number of times of dropping leading to breakage when EF is 1×10[(J/m)/(N/m)] is 10 times or more, and the number of times of dropping leading to breakage when EF is 5×10[(J/m)/(N/m)] is more than 30 times, EF being obtained by dividing a dropping energy density in the drop test by a fracture stress of the solid food.

An atomization devicecomprises a casing, a rotordisposed rotatably with respect to the casing, and a statordisposed on the same axis line with the rotor. The rotorincludes a first rotor cylinder portionand a second rotor cylinder portionwhich have a plurality of through-holes provided in peripheral walls thereof and which are disposed concentrically. The statorincludes a main-stator cylinder portionand an inside sub-stator cylinder portionwhich have a plurality of through-holes provided in peripheral walls thereof and which are disposed concentrically. The rotoris fixedly positioned with respect to the casing. The statoris movable by a lifting/lowering meansin the axial line L direction.

Atomization device

An object of the present invention is to develop a mechanism capable of more effectively performing processing such as emulsification, dispersion, dissolution, atomization, mixing, or stirring on a processing object with fluidity using an atomization device including a rotor-stator type mixer while an inside of a processing tank is maintained in a pressured state, at atmospheric pressure, or in a vacuum state, and occurrence of a negative pressure state on a center side (inner diameter side) of a rotor is actively suppressed or prevented. An atomization device comprises a rotor-stator type mixer in a processing tank. The atomization device performs processing such as emulsification, dispersion, atomization, mixing, or stirring on a processing object with fluidity using the rotor-stator type mixer while an inside of the processing tank is maintained in a pressured state, at atmospheric pressure, or in a vacuum state. The atomization device has a mechanism in which the rotating rotor makes the processing object flow at a predetermined pressure or higher.
