Abstract: An AC electric field-assisted refrigerating container comprises: an outer container casing made of metal and having a storage chamber thereinside; an inner container casing formed of a dielectric panel and disposed inside the outer container casing; cooling means to cool an inside of the storage chamber; a plurality of insulated electrodes each formed by densely covering an entire circumference of an electrode plate with an insulator and disposed on an inner wall of the inner container casing; and a transformer for supplying an AC of 10 to 20 VA, at a voltage of 2000 to 4000 V and a frequency of 50 to 60 Hz, wherein the transformer has a ground terminal; wherein the refrigerating container is configured to cause AC discharge from the insulated electrodes to form an AC electric field inside the storage chamber, wherein, as a result of the AC discharge, electrons are supplied to the inner container casing formed of the dielectric panel, and then flow throughout the inner container casing, thereby allowing the e

Abstract: Disclosed is a drying apparatus equipped with linear drive mechanisms to drive spray nozzles in the direction perpendicular to the direction in which a wet object is transferred in the drying box. Each spray nozzle has a long discharge slit elongated in the direction in which the wet object is transferred. Two opposed nozzles are provided at each of the entrance and exit of the drying box. Each nozzle has an elongated slit traversing the width of the wet object in the direction perpendicular to the transporting direction, the opposed surfaces of the nozzles being so inwardly oblique that the gap between the opposed surfaces is larger at the inner edge than the outer edge.

Abstract: Disclosed is a high-speed drying apparatus for drying objects which are rinsed with non-volatile or volatile liquid. The drying apparatus is capable of quickly drying such objects at a reduced cost, not permitting their oxidation. First, the rinsing liquid remaining on objects is substantially removed, still allowing small quantities of rinse to remain thereon. The substantial removal step is immediately followed by the complete removal of the still remaining liquid in the super dry atmosphere.
