Stream down type ice making machine

Abstract

A stream down type ice making machine having an ice making plate in which an ice making region is defined between a pair of vertical ribs, the pair of vertical ribs being spaced apart in the width direction and projecting from an ice making face and an evaporator disposed meanderingly in the back face opposite to the ice making face of the ice making plate, the ice making region of the ice making plate is cooled by cyclically supplying the evaporator with a refrigerant as well as ice-making water is supplied to flow down thereon so that many a lump of ice is produced on the ice making region, wherein protrusions projecting to the ice making region side and having a slope formed on the upper face thereof, the slope being inclined from above to down as being away from the ice making face, are provided in the vertical rib.

Description

BACKGROUND OF THE INVENTION [0001] 1. Technical Field [0002] This invention relates to a stream down type ice making machine that produces lumps of ice in an ice making region by flow-supplying an ice-making water in the ice making region of an ice making plate in which an evaporator is arranged in the back face thereof. [0003] 2. Description of the Related Art [0004] As the ice making machine for producing lumps of ice continuously, there is known a stream down type ice making machine, wherein a pair of ice making plates are arranged vertically opposite to an evaporator being sandwiched therebetween, the evaporator constituting a freezing system, and an ice-making water is spray-supplied onto the surface (the ice making face) of each of the ice making plates to be cooled with refrigerant, the refrigerant being cyclically supplied to the evaporator, thereby forming a lump of ice, and then the obtained lump of ice is peeled off to be discharged by falling. [0005] In the deicing opera...

AI Technical Summary

Benefits of technology

[0006] The projecting height from the ice making face of the protrusion needs to be such an adequate size that the lump of ice having run over the protrusion will not be caught by the lump of ice of the downside. Namely, if the projecting height is inadequate, the lump of ice will be caught by the lump of ice of the downside, so that it will not fall promptly, thereby causing such problems as that the deicing time becomes long to decrease the daily ice making capacity, that the amount of lump of ice melting wastefully on the ice making face increases thereby to decrease the daily ice making capacity and to produce ice of abnormal shape, and that the power consumption and the amount of consumed water increase.

[0008] Namely, the present invention has been proposed, in view of the problem inherent in the conventional art described above, to resolve this suitably, and is intended to provide a stream down type ice making machine capable of facilitating falling of lumps of ice without producing distortion and the like in the ice making face.

Problems solved by technology

Namely, if the projecting height is inadequate, the lump of ice will be caught by the lump of ice of the downside, so that it will not fall promptly, thereby causing such problems as that the deicing time becomes long to decrease the daily ice making capacity, that the amount of lump of ice melting wastefully on the ice making face increases thereby to decrease the daily ice making capacity and to produce ice of abnormal shape, and that the power consumption and the amount of consumed water increase.

However, if high protrusions are molded in the ice making face by press work, distortion and the like are produced in the ice making face, thereby causing a problem affecting the ice making capacity.
