CONSTITUTION:Unidirectional freezing operation is effected by cold air from the surface of water toward the lower part of the same by the heating effect of a heater 32 from the lower surface of a heat insulating tank 28 and when a driving device 40 is operated subsequently, an ice making pan 33 is pivoted and converted whereby water, not frozen yet, is separated and is discharged through a drainage pan 46 and a drainage pipe 47, which are provided below. Subsequently, when a water cutting pan 37, having ice thereon. is pivoted and turned over, the ice drops into an ice reserving box 50. On the other hand, when a vessel 70 for manufacturing ice cream is set and the driving device 40 is operated, the mix 78 of ice cream is cooled and agitated, then, the crystal of ice is pulverized while rolling the mix by the rotating effect of the spiral rotary body 66.

Abstract: PURPOSE:To permit the selective use of an automatic ice cream manufacturing device by a method wherein a repeatedly swinging agitating vane is replaced with a vessel, whose upper surface is opened and whose bottom surface is provided with a curved configuration coinciding with the locus of motion of an agitating vane and both end surfaces are curled inwardly continuously with the curved surface of the bottom surface. CONSTITUTION:When mix 35 is thrown into a vessel 33 and a driving device 13 is operated, a driving motor 24 is started and a reduction gear 25 is also rotated in conjunction with the motor 24. When the reduction gear 25 is rotated, an agitating vane 30, connected to a last stage gear, starts swinging motion. The vessel 33 for manufacturing ice cream, which is provided instead of the ice reserving box of an automatic ice making device and made of a metal such as aluminum or the like, is provided with an upper opening and a bottom surface having curved configuration coinciding with the locus of the motion of the agitating part 32 of the agitating vane 30 while both end parts are curled so as to be continuous with the configuration of the curved surface. An automatic ice cream manufacturing device 34 is constituted of the driving device 13, a frame 21, the agitating vane 30 and the vessel 33.

Abstract: PURPOSE:To improve freshness retentivity by forming a cold air duct in a support of a shelf provided in a freezing chamber and introducing part of cold air to be fed from a cooler to a door shelf. CONSTITUTION:At a normal time, a compressor 9 and a blower 11 are turned ON, OFF based on a set value of a temperature sensor 13 in a freezing chamber 6, cold air cooled by a cooler 10 is fed by the blower 11, and rapidly cooled so that the chamber 6 and a rapidly cooling chamber 18 hold a predetermined temperature (e.g. -20 deg.C). In this case, part of the cold air by the blower 11 is introduced from a cold air inlet 28 to a cold air duct 27 provided at a support 26 of a shelf 25 to cool a door shelf 22. Foods contained in door pockets 23a, 23b are so cooled as to hold the predetermined temperature (e.g. -20 deg.C) by a special purpose cold air duct 27 irrespective of a containing amount in the chamber 6, and hence an equivalent quality to that in the chamber 6 can be held. Thus, freshness retentivity can be held.
