Abstract: A production system of electrolyzed water of the type which includes a first brine tank arranged to store an amount of saturated brine, a second brine tank arranged to be supplied with the saturated brine from the first brine tank through an electrically operated pinch valve and fresh water from an external source of water through an electrically operated water supply valve for storing an amount of diluted brine, and an electrolyzer arranged to electrolyze the diluted brine supplied from the second brine tank for production of electrolyzed water.

Abstract: A production system of electrolyzed ion water wherein acid ion water and alkaline ion water are produced by electrolysis of water or brine between a pair of electrodes in an electrolyzer and discharged through discharge conduits for use in appropriate manner, and wherein DC voltage between the electrodes is inverted in polarity to eliminate contaminants adhered to the negative electrode in the electrolyzer. In the production system, invert ion water produced in the electrolyzer at a cleaning mode is discharged in such a manner as to be used as proper ion water, and the contaminants are eliminated without causing entry of the invert ion water into a storage tank of proper ion water.

Abstract: A production system of electrolyzed water which includes a first brine tank arranged to store an amount of saturated brine, a second brine tank arranged to store an amount of diluted brine prepared by dilution of the saturated brine supplied from the first brine tank and an electrolyzer for electrolyzing the diluted brine supplied from the second brine tank. In the production system, an electric controller is adapted to maintain the level and concentration of diluted brine in the second brine tank and to correct the concentration of the diluted brine in accordance with a temperature of the diluted brine or pH of electrolyzed water produced in the electrolyzer.

Abstract: An auger type ice making mahine has a refrigerator, an ice making cylinder for forming a layer of ice in cooperation with the refrigerator, and a top ice storage chamber in communication with the ice making cylinder for storing ice discharged therefrom. A bottom ice storage chamber is disposed below the top ice storage chamber for receiving and storing ice transferred from the top ice storage chamber. The top ice storage chamber is equipped with a top ice storage level detector for detecting the amount of ice stored within the top chamber, an ice dispensing gate mechanism capable of dispensing ice pieces stored in the top ice storage chamber outwardly therefrom, and an ice transfer system capable of transferring ice pieces from the top ice storage chamber to the bottom ice storage chamber. The bottom ice storage chamber is provided with a bottom ice storage level detector for detecting the amount of ice stored within the bottom chamber.
