Sterilizing apparatus and manufacturing apparatus for liquefied product

A sterilizing apparatus comprising:

• a cylindrical casing having openings at both ends thereof;
• cover bodies respectively having through holes detachably mounted on said openings of said cylindrical casing;
• a heating portion comprising a heating element having a first inlet through which a raw material to be heated is introduced, and a first outlet through which a heated raw material is discharged, and a heating means for heating said heating element;
• a cooling portion comprising a cooling element having a second inlet through which a raw material to be cooled is introduced, and a second outlet through which a cooled raw material is discharged, and a cooling means for cooling said cooling element;
• a heat insulating material interposed between said heating portion and said cooling portion respectively provided in said casing, an outer diameter of said heat insulating material being smaller than an inner peripheral surface of said casing;
• wherein said heating element and said cooling element each concentrically comprises a pair of larger and smaller diameter heat transfer discs having a plurality of polygonal chambers thereon which are open at fronts thereof, in each pair said larger and smaller diameter heat transfer discs being coupled to each other face to face, wherein said chambers of said larger and smaller diameter transfer discs are alternately arranged with one another so as to communicate with one another, and said larger diameter heat transfer disc has a circulation hole formed at a center of said heat transfer disc;
• wherein said larger diameter heat transfer discs are disposed in said casing and peripheries of said larger diameter heat transfer discs are brought into close contact with said inner peripheral surface of said casing;
• wherein said circulation hole of said heating element serves as said first inlet and circumferential openings define between said larger and smaller diameter heat transfer discs serve as the first outlet, and said circulation hole of said cooling element serves as said second inlet and said circumferential openings between said larger and smaller diameter heat transfer discs serve as said second outlet;
• wherein an inner space defined between said heat insulating material and said inner peripheral surface of said casing serves as a raw material connecting passage for connecting said first outlet of said heating element and said second inlet of said cooling element, in which said first inlet and said first outlet of said heating element communicate with said through holes;
• a first heating chamber, which is heated, contacts a rear surface of said larger diameter heat transfer disc of said heating element in said heating means;
• a second heating chamber, which is heated, contacts a rear surface of said smaller diameter heat transfer disc;
• a first cooling chamber, which is cooled, contacts the rear surface of said larger diameter heat transfer disc of said cooling element in said cooling means;
• and
• a second cooling chamber, which is cooled, contacts the rear surface of the smaller diameter heat transfer disc, of said cooling element in the cooling means.
