  • Patent number: 6381975
    Abstract: Disclosed is an ice dispenser in which an agitating device (11) is operated only when necessary to thereby prevent ice cubes in an ice storage vessel (18) from sticking together, allowing ice to be smoothly discharged from the ice storage vessel (18). The ice dispenser includes an ice-making device (1), the ice storage vessel (18), an ice discharge port (41), an agitating device (11) for agitating the ice in the ice storage vessel (18), and an operation control device (30) which operates the agitating device (11) at the time of ice discharge or ice-making operation and which causes, when no ice-making operation is being performed, the agitating device (11) to operate after an interval of a predetermined first set time for a predetermined second set time by timer means (TM 1, TM 2), wherein when the agitating device (11) is stopped by stopping the ice discharge or ice-making operation, the operation control device (30) resets the timer means (TM 1) to start the first set time.

  • Patent number: 6257009
    Abstract: An ice dispenser operates an agitator only when necessary so as to prevent ice in an ice storage compartment from fusing and sticking to each other, thereby ensuring smooth release of ice from the ice storage compartment. The ice dispenser is formed of an ice maker, an ice storage compartment, an ice releasing port, an agitator for agitating ice in the ice storage compartment, and an operation controller. The controller operates the agitator when releasing ice and making ice, and causes the agitator to operate for a predetermined second set time after allowing an interval of a predetermined first set time to pass by using a timer means when no ice is being made. The operation controller resets the timer means to start counting the first set time when an ice release or an ice making operation is stopped and the agitator is stopped.

  • Patent number: 5798028
    Abstract: A production system of electrolyzed water includes an electrolyzer the interior of which is subdivided into an anode chamber and a cathode chamber by means of a cation permeable membrane, a diluted brine tank arranged to store an amount of diluted brine to be supplied into the anode and cathode chambers of the electrolyzer, first and second water supply conduits connecting the brine tank to the anode and cathode chambers respectively, and first and second electrically operated hydraulic pumps provided on the first and second water supply conduits to supply the diluted brine from the brine tank into the anode and cathode chambers. To prevent an electric motor for the hydraulic pumps from corrosion caused by backward flow of electrolyzed water in the production system, the hydraulic pumps are deactivated upon the lapse of a predetermined time after application of the DC voltage to an anode and a cathode in the anode and cathode chambers has been interrupted.

  • Patent number: 5792343
    Abstract: A brine supply system including a first brine tank to store diluted brine of a predetermined concentration to be supplied into an electrolytic brine treatment device and a second brine tank to store an amount of saturated brine at a predetermined concentration. When the level of diluted brine becomes a lower limit level, the first brine tank is supplied with fresh water from an external supply source of water until the level of diluted brine becomes an upper limit level and is intermittently supplied with a predetermined amount of the saturated brine from the second brine tank. Based on a previously memorized supply time of the fresh water, a supply frequency and a supply interval of the saturated brine for the memorized supply time are calculated to maintain the diluted brine at the predetermined concentration even when the first brine tank is being supplied with the fresh water.

  • Patent number: 5665419
    Abstract: A material consisting mainly of protein and water is supplied into an extruder through a supply port, mixed by screws and extruded from an extrusion port. The extrusion port is provided with a die including a plate having a plurality of holes. A mixture extruded from the extrusion port is provided with a fibrous orientation. The die has a cooling mechanism for cooling the mixture extruded from the extruder. The obtained protein material is heated and compression-molded by a pressing machine, and a protein food having a meat-like texture and mouth feeling is produced. Thus, a high-protein, low-calorie protein food having a meat-like complex texture and mouth feeling can be produced by a simple process.

  • Patent number: 4838702
    Abstract: An electric control apparatus for an icecream-making machine wherein a stirring paddle is settled in an icecream-forming container in conditions for thermal exchange with an evaporator of a refrigerating system and is driven by an electric motor to whip icecream ingredients stored in the container. The electric control apparatus is arranged to detect the rotational speed of the paddle for producing a pulse signal at a period inversely proportional to the detected rotational speed, to produce an output signal when 1/n of the period of the pulse signal is more than a predetermined period of time and to cease production of the output signal when 1/n of the period of the pulse signal becomes less than the predetermined period of time, and to permit supply of an electric power to the motor when production of the output signal is ceased and to cut off the supply of the electric power to the motor in response to the output signal.
