Vapor tank
 A vapor tank for processing a product by heating the same through exposure to vapor serving as a heat transfer medium. The vapor tank includes at least one partition wall separating a vapor chamber filled with vapor and a heating chamber for processing the product by heating the same for supplying a sufficient saturated vapor to the product. The partition wall is formed with openings for allowing the saturated vapor to be injected therethrough from the vapor chamber into the heating chamber where the product is enveloped by the saturated vapor. The vapor tank is provided with a recovery device for recovering the vapor flowing out of the tank through an inlet and an outlet for introducing and discharging the product into and out of the tank with a high degree of vapor recovering efficiency and with a minimum loss of energy. The vapor tank is also provided with a mechanism for externally supplying air currents to prevent the vapor from flowing out of the tank through the inlet and the outlet.
