Patent number: 5707672Abstract: A method for sterilizing and packing a solid food comprises the steps of charging a solid food in a retainer, whose upper portion is opened, in a layer having an approximately uniform thickness, sterilizing the retainer through heating, cooling it with cooling air and/or cooling water, transferring the solid food contained in the retainer to a sterilized packaging container and then aseptically sealing the container. The method permits efficient and rapid heating and cooling of a solid food because of the direct contact between steam or cooling air and/or cooling water and the food without causing a problem such that the packaging container becomes dirty during the sterilization through heating and does not give out any remaining bad smell. Therefore, excess softening and/or destruction of the solid foods as well as any deterioration thereof due to decomposition and alteration of the nutritive substances and flavoring substances present therein can thus be limited to the lowest possible level.Type: GrantFiled: August 24, 1995Date of Patent: January 13, 1998Assignee: House Foods CorporationInventors: Masao Taguchi, Yoshitaka Hirano, Koji Sengoku, Masayuki Nakatani, Mahito Orii, Akifumi Fujita
