The present invention relates to a rotary drum type soft ice maker, and more particularly, to a rotary drum type soft ice maker which makes powder ice powder by freezing de-icing water and maximizes the cooling efficiency of the coolant.

In a conventional apparatus for manufacturing powdery ice, a rotating ice drum is formed by freezing the water film formed on the surface while the compressed refrigerant vaporizes in the rotating drum while the cylindrical rotating drum is rotated in a state of being accommodated in the rotating drum. It was possible to manufacture the powdered ice by cutting the frosted film by the disposed cutting edge.

In order to freeze the ice film on the surface of the rotary drum, spray nozzles for spraying the coolant are arranged at predetermined intervals.

However, since the injection nozzles are mounted in a separate refrigerant supply mode in which each refrigerant is supplied, a plurality of refrigerant supply pipes corresponding to the arranged injection nozzles must be inserted into the rotary drum, so that the rotary drum is enlarged, There has been a problem that the control equipment for supplying the refrigerant having a constant pressure and temperature becomes complicated.

In addition, since a large-capacity compressor must be used in order to supply the refrigerant with a sufficient pressure to each refrigerant supply pipe, not only the cost of constructing the cooling facility is increased but also the power consumption required for driving the compressor is increased, .

2 is a side cross-sectional view showing a configuration of a rotary drum type soft ice maker according to a preferred embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

It should be construed in accordance with the principles of the present invention that it is possible to define the present invention in a manner that is consistent with the technical idea of the present invention. And it is to be understood that various equivalents and modifications may be substituted for them at the time of filing the application.

The rotary drum type soft ice maker 100 according to the preferred embodiment of the present invention is configured such that the coolant supplied to the capillary tube 130 is distributed to each injection nozzle 150 through the branch pipe 140, 1 and 2 (a) and 2 (b) are views showing an ice making apparatus according to a second embodiment of the present invention. A coolant supply pipe 120, a capillary tube 130, a branch pipe 140, a spray nozzle 150, and a coolant suction pipe 160, as shown in FIG.

First, the rotary drum 110 is a base member that provides a space for manufacturing the powdery ice 20, and is formed into a cylindrical shape having a closed evaporation space 111 therein, and a ice-making plate 112 is formed around the rotary drum 110 And is horizontally disposed on the upper portion of the head 30 in a rotatable manner. On one side thereof, a cutting edge 113 for scraping freezing ice from the ice making plate 112 is provided.

The rotary drum 110 is disposed on the upper portion of the head 30 and is positioned so as to be submerged in the iced water 10 stored in the head 30 and is rotated by the driving motor ) On the surface of the substrate.

The supporter 30 is connected to an ice-making water supply module 182 for supplying ice-making water 10 such as water, beverage or milk and a ice-making water supply line L3 to periodically supply the ice- So that a certain amount of deicing water 10 can always be stored.

In addition, an ice receiving vessel 40 for receiving the powdery ice 20 generated by scraping of the frozen ice is disposed at a lower position of the cutting edge 113.

The refrigerant supply pipe 120 is a pipe for supplying the refrigerant necessary for manufacturing the powdery ice 20 and is inserted into the rotary drum 110 and connected to the capillary 130 to supply the refrigerant.

2, the refrigerant supply pipe 120 is connected to the refrigerant circulation module 181 for supplying the compressed refrigerant and the refrigerant supply line L1, and is supplied with a predetermined amount of the refrigerant and injected into each capillary 130 do.

The refrigerant circulation module 181 is a module for supplying refrigerant to the refrigerant supply pipe 120 and recovering the refrigerant discharged through the refrigerant suction pipe 160. The compressor 181 compresses the refrigerant to a high pressure and circulates the refrigerant, And a condenser (not shown) for cooling and liquefying the compressed refrigerant.

The capillary tube 130 is disposed inside the rotary drum 110 and has one end connected to the refrigerant supply pipe 120 and the other end aligned with the extended horizontal length of the rotary drum 110, The branch pipe 140 branches from the other end of each capillary tube 130 toward the inner surface of the ice making plate 112 into a plurality of flow paths.

The injection nozzle 150 is connected to an end of each branch pipe 140 and injects the refrigerant supplied toward the inner surface of the ice making plate 112.

As shown in the drawing, each injection nozzle 150 is preferably spaced apart at equal intervals along the extended horizontal length of the rotary drum 110 in consideration of the spray angle. In addition, it is preferable that the region where the coolant is injected from each injection nozzle 150 is continuously connected.

The refrigerant suction pipe 160 is a duct for collecting the refrigerant sprayed by the spray nozzle 150 in the evaporation space 111 of the rotary drum 110. The refrigerant suction pipe 160 is inserted into the rotary drum 110, A plurality of suction holes are formed along the extended longitudinal direction to suck the injected refrigerant.

Here, the refrigerant suction pipe 160 is connected to the refrigerant circulation module 181 through a refrigerant recovery line L2 to discharge the refrigerant.

The refrigerant supplied to the capillary 130 as described above is distributed to the respective injection nozzles 150 through the branch pipe 140 and uniformly sprayed to the entire ice making plate 112 of the rotary drum 110 to form a uniform ice film Thereby making it possible to manufacture powdered ice having a constant particle size and to increase the cooling efficiency, thereby miniaturizing the cooling equipment such as the compressor.

Since the respective injection nozzles 150 are spaced equidistantly along the extended horizontal length of the rotary drum 110 in consideration of the spray angle, the positions of the ice-making plates 112 opposed to the respective spray nozzles 150 It is possible to cool the entire ice-making part of the ice making plate 112 to a predetermined cooling temperature.

It is preferable that the injection nozzle 150 has an injection port having a diameter that is relatively larger than a diameter of the capillary tube 130 and preferably has an injection port having a diameter that is about twice the diameter of the capillary tube 130 Do. Therefore, it is possible to realize the effect of eliminating the loss of the expansion pressure and being widely sprayed on the surface of evaporation and evaporating within a short time.

When the refrigerant is injected into the rotary drum 110, the lubricating oil is deposited in the rotary drum 110, and the rotary drum 110 is rotated. The cooling effect of the heat exchanger 110 can be reduced. In addition, the refrigerant injected into the rotary drum 110 may be settled on the bottom surface while a part of the refrigerant is liquefied.

The rotary drum type soft ice maker 100 according to a preferred embodiment of the present invention is provided with a recovery pipe 170 for recovering lubricating oil and coolant 190 that are pumped in the rotary drum 110, .

As shown in the drawing, one end of the return pipe 170 is inserted into the rotary drum 110 and extended to a lower position, and the other end is connected to the refrigerant suction pipe 160 or the refrigerant recovery line L2 And sucks and discharges the lubricating oil and coolant 190, which are accumulated on the bottom surface of the rotary drum 110. Since the lubricating oil and the coolant 190 remained in the rotary drum 110 can be removed through the recovery pipe 170, the cooling efficiency can be improved by the relatively high temperature of the lubricating oil retained in the rotary drum 110. [ Can be effectively prevented from lowering.

Since the capillaries 130 and the injection nozzles 150 are linearly spaced apart from each other along the extended horizontal length of the rotary drum 110, the distance between the capillaries 130 and the injection nozzles 150 is different from that of the refrigerant supply pipe 120 for supplying the refrigerant. There is no other choice. In this case, when the diameters of the capillary tube 130 and the injection nozzle 150 are the same, the injection pressure of the coolant supplied to the capillary tube 130 and the injection nozzle 150, which are far from the coolant supply tube 120, The injection pressure may be lowered relatively.

In order to prevent such a phenomenon in the rotary drum type soft ice maker 100 according to the preferred embodiment of the present invention, when the diameter of each capillary tube 130 is the same, each injection nozzle 150 is connected to the refrigerant supply tube 120, The larger the diameter of the jet opening is, the larger the diameter of the jet opening can be.

Alternatively, when each injection nozzle 150 is provided with an injection port having the same diameter, each of the capillaries 130 can have a gradually larger diameter as the separation distance (extended length) from the refrigerant supply pipe 120 is increased .

Since each injection nozzle 150 or each capillary 130 has a jet opening having a gradually larger diameter or a larger diameter as the distance from the refrigerant supply pipe 120 to which refrigerant is supplied is increased, The effect of uniforming the injection pressure of the coolant injected through each injection nozzle 150 can be provided.

The branch pipe 140 and the capillary pipe 130 are disposed inside the rotary drum 110 and supported by the support frame 121 fixed to the refrigerant pipe 120 or the refrigerant suction pipe 160, So that it can be fixedly installed more stably.

As described above, although the present invention has been described with reference to specific embodiments and drawings, it is to be understood that the present invention is not limited thereto and that various changes and modifications may be made without departing from the spirit and scope of the present invention by those skilled in the art. It is to be understood that various modifications and changes may be made without departing from the scope of the appended claims.
