Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.

Fig. 1 shows a device for producing powdered ice, which is a constitution for explaining an embodiment of the present invention.

The apparatus for manufacturing a powder ice in which the embodiment of the present invention is applied includes a drive source 1, a drum 3, a water tank 5, a cutter 7, and a cooling device 9.

The driving source 1 may be installed inside the case C, and a motor may be used. The driving source 1 is coupled to a sprocket on a driving shaft and can transmit a rotational force to the drum through a chain coupled to the sprocket.

The drum 3 is provided with a space therein and quenching is performed by the cooling device 9 so that ice can be produced on the outer circumferential surface. The water bottle 5 supplies water to the outer periphery of the rotating drum 3, in which a part of the drum 3 is contained, and supplies water to the outer periphery of the drum 3 to freeze the ice. It is preferable that the water bottle 5 is installed at the lower part of the drum 3. [

And a cutter 7 is disposed at a position adjacent to the outer periphery of the drum 3. [ The cutter 7 serves to cut frozen ice on the outer peripheral surface of the drum 3.

The cutter 7 has a cylindrical shape and includes a first cutter 11 having a spiral cutter disposed on the outer peripheral surface thereof and a second cutter 13 disposed on the outer periphery of the drum 3 and having a cutting edge.

The first cutter 11 can be rotated by receiving the driving force of the driving source 1. [ The first cutter 11 is spaced apart from the drum 3 by a predetermined distance to cut the frozen ice on the outer periphery of the drum 3 to form a piece of ice. It is preferable that the first cutter 11 has a cylindrical shape, and the outer peripheral surface of the first cutter 11 has a spiral continuous cutting value.

The second cutter 13 is provided with a cutting edge to cut frozen ice on the outer periphery of the drum 3 to a predetermined thickness to produce powdery ice such as snow.

The cooling device 9 serves to quench the drum 3. 2, the cooling device 9 for cooling the drum 3 in the embodiment of the present invention includes a compressor 11, a condenser 13, an expansion part 15, an evaporator 17, An internal heat exchanger 19 may be included.

The compressor (11) can compress the refrigerant to a high temperature and a high pressure and transfer the refrigerant to the condenser (13).

The condenser 13 is connected to the compressor 11 and the refrigerant pipe P1 to dissipate the heat of the refrigerant to the outside.

The expansion unit 15 is connected to the condenser 13 and the refrigerant conduits P2 and P3 to expand the refrigerant. In the embodiment of the present invention, the expansion part 15 may be formed of a spray nozzle (not shown) for spraying the coolant into the drum 3. [

The evaporator 17 serves to cool the drum 3 by absorbing the external heat of the expanded refrigerant. The evaporator 17 has a structure in which the drum 3 is quenched while absorbing external heat from the drum 3 when the refrigerant is injected into the drum 3 by the jet nozzle constituting the expansion part 15 .

The internal heat exchanger 19 is installed in refrigerant lines P 2 and P 3 connecting the condenser 13 and the expansion portion 15 and refrigerant lines P 4 and P 5 connecting the evaporator 17 and the compressor 11 Heat transfer of the refrigerant can be achieved. That is, the internal heat exchanger 19 includes an inner case 23 constituting a liquid-receiving chamber 21 and an outer case 27 constituting a liquid-separating chamber 25.

It is preferable that the liquid chamber 21 is connected between the refrigerant conduits P2 and P3 connecting the condenser 13 and the bulging portion 15. [ And the liquid separation chamber 25 is connected between the refrigerant conduits P4 and P5 connecting the evaporator 17 and the compressor 11. [ At the same time, it is preferable that the liquid separation chamber 25 is arranged so as to surround the outer surface of the liquid chamber 21. That is, the outer case 27, which constitutes the liquid separation chamber 25, is disposed in a sealed space while surrounding the outer circumference of the inner case 23 constituting the liquid-receiving chamber 21.

The inner case 23 may be made of a metal material having excellent heat transfer. Therefore, the heat of the refrigerant passing through the liquid chamber 21 can be transferred to the refrigerant passing through the liquid separation chamber 25.

The operation of the embodiment of the present invention will be described as follows.

The drum 3 is rotated by the driving force of the driving source 1. [ Since the drum 3 is partly locked in the water tank 5, water is continuously supplied to the outer circumferential surface. The drum 3 is quenched by the cooling device 9. The water on the outer peripheral surface of the drum 3 rapidly freezes while the drum 3 is cooled rapidly. Then, the frozen ice on the outer periphery of the drum 3 is cut by the cutter 7 to produce a piece ice or powder ice. That is, the chipped ice is made by the first cutter 11, and the powdered ice is made by the second cutter 13.

The process of quenching the drum 3 by the cooling device 9 will now be described in more detail.

The cooling device 9 compresses the refrigerant at a high temperature and a high pressure by the compressor 11 and transfers it to the condenser 13 through the refrigerant line P1. The refrigerant having passed through the condenser 13 passes through the liquid chamber 21 through the refrigerant line P2. The refrigerant having passed through the liquid chamber 21 is transferred to the expansion portion 15 by the refrigerant line P3. The expansion portion 15 is made up of an injection nozzle (not shown), and the coolant is injected into the drum 3 by the injection nozzle.

The refrigerant is gasified while being injected into the drum 3. Then, the drum 3 is rapidly cooled while absorbing the external heat, so that the water on the outer peripheral surface of the drum 3 is frozen. That is, the drum 3 functions as the evaporator 17.

The refrigerant injected into the drum 3 is transferred to the liquid separation chamber 25 through the refrigerant line P4. The refrigerant transferred to the liquid separation chamber 25 can absorb the heat of the liquid chamber 21 and is transferred to the compressor 11 through the refrigerant pipeline P5.

At this time, the refrigerant passing through the liquid separation chamber 25 absorbs the heat of the refrigerant passing through the liquid-receiving chamber 21 and is transmitted to the compressor 11, so that the liquid-receiving chamber 21 can serve as a receiver. The liquid separation chamber 25 may serve as a liquid separator. That is, the refrigerant passing through the liquid chamber 21 and the liquid separation chamber 25 is heat-exchanged, thereby maximizing the efficiency of the evaporator 17.

Therefore, the embodiment of the present invention maximizes the cooling efficiency of the drum 3, so that the ice can be frozen on the outer circumferential surface of the drum 3 to produce high-quality piece ice or powder ice.

The embodiment of the present invention can reduce the number of parts by reducing the number of parts by constituting the liquid-receiving chamber 21 and the liquid-separating chamber 25 as a single part, thereby reducing the number of parts during assembly work of the refrigerating cycle. Maintenance costs can be reduced.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And it goes without saying that the invention belongs to the scope of the invention.
