Description

Auger ice maker {AUGER TYPE ICE MAKER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auger ice maker, and more particularly, to an auger ice maker which scrapes and grows an ice layer that grows on an inner circumferential surface of an ice making machine from an inner circumferential surface of the auger and is scraped off by an upward pressure head.

Conventionally, in this type of auger ice maker, the ice scraped from the inner circumferential surface of the ice maker on the outer periphery of the auger is deposited in the spiral space between the upper and lower spiral blades, and is pushed to the upper pressurizing head and transported. It is known that the air escape port through which air escapes to the outside through the air escape hole of a main body shaft part is provided. This air release port is attached to the connecting portion of the spiral blade body.

That is, this type of auger ice maker fills the ice making water to a predetermined level L in the ice making container as illustrated in FIG. 2, and in this state is closely contacted with the outer circumference of the ice making container and wound by a refrigerant pipe fixed in a spiral shape. By cooling an ice bin to below freezing point, an ice layer grows on the inner peripheral surface of an ice maker.

The ice layer growing on the inner circumferential surface of the ice tray in the ice-making water filled with the ice-making water up to the predetermined level L is scraped off by the auger's spiral blade and is gradually accumulated in the spiral space between the spiral blades and pushed upward toward the pressure head. It is conveyed and introduced into the compression passage of this pressure head.

However, in recent years, with the advance of the cooling technology (icemaking technology) of the ice-cream container by the evaporator which becomes the spiral pipe wound on the outer peripheral surface of an ice-making container, the hardness of the ice layer formed by the growth by freezing on the inner peripheral surface of an ice-making container. (Hardness) and the like are improved, whereby the ice layer is not only scraped up to be cut by the auger's spiral blade, but also exists at a predetermined spiral pitch as illustrated in the enlarged view of FIG. In the height range of the spiral space between the spiral blades, the ice layer is scraped up so as to be peeled into thin pieces or plates, but as in the prior art, the air trapping hole is located at the base of the spiral blade and is installed on the outer periphery of the main body. It is difficult for air to escape quickly to the outside.

In addition, in the process of scraping and conveying the ice to the upper pressure head by the auger, if the air does not escape to the outside, the hard rod is introduced into the compression passage of the pressure head and most of the moisture is removed by compression. When adjusted to shape, it remains incorporated in the rod-shaped ice column, which is a major factor causing the deterioration of the ice quality.

The present invention has been made in view of such a conventional situation, and an object of the present invention is to provide a spiral space between upper and lower spiral blades in which an ice layer which is scraped off and peeled off in thin slices or plates by an auger from the inner circumferential surface of the ice making cylinder is peeled off. It is to provide an auger ice maker equipped with an auger which is improved so that the air present in the spiral space with the ice layer in the process of scraping up to the pressure head of the upper portion while being stacked to be stacked on the top.

In order to achieve the object, in the present invention, a vertical ice-making barrel, an auger disposed coaxially in the ice-making barrel, a refrigerant pipe closely wound on the outer circumference of the ice-making cylinder, and wound in a spiral shape, and an upper portion of the ice-making cylinder. In an auger ice maker having a pressurized head fixedly disposed on the side, the auger is a spiral blade made of a predetermined spiral pitch on the outer periphery of the main body portion, and is located approximately in the center between the upper and lower spiral blades. On the outer circumference of the body portion, an air bleed opening connected to the air bleed hole that is pulled out toward the upper end side along the axis of the body portion is provided.

Moreover, the blade thickness of the spiral blade which scrapes an ice layer and peels off from the inner peripheral surface of an ice maker is made into 1-3 mm.

According to such technical means, the ice layer peeled off by scraping thin slices or plates from the inner circumferential surface of the ice making container as the height range of the spiral space between the spiral blades existing above and below the auger is piled up to be stacked in the spiral space. When it is scraped and conveyed to the pressure head of the air, the air trapped in the spiral space by the ice layer quickly escapes to the outside through the air bleed hole from the air bleed opening that is opened in the main body part of the central portion of the spiral space.

An embodiment of the present invention will be described based on the drawings.

1 is a front view showing an example of an embodiment of the auger 1 in the auger ice maker of the present invention, Figure 2 is the overall configuration of the auger ice maker produced by embedding the auger 1 rotatably in the ice making chamber 2 A longitudinal sectional view showing an example of the.

This auger ice maker is in close contact with the outer circumference of the ice maker 2 and sends a reduced pressure refrigerant into the refrigerant pipe 3 fixedly mounted in a spiral shape to circulate. The ice maker 2 cools the ice maker 2 below the freezing point, and the ice making water sent to the ice maker 2 is The ice layer formed on the inner circumferential surface, and the ice layer formed by the growth due to the freezing is scraped upward by being peeled into thin slices or plates by spiral blades 1-2 of Auger 1, and the pressurized head 4 above the ice tray 2 Compression (dehydration) of the passageway 5 is introduced into the compression passage 5 of the rod, and most of the moisture is adjusted to the rod shape, the rod-shaped ice column hits the ice cutting section 6 of the upper compression passage 5 It consists of a chunk of chip-shaped ice of the appropriate size, and is constructed so that the chunks of ice are formed continuously. And this ice block is stored in the storage part which is not shown in figure.

Auger 1 consists of a main body 1-1 and a spiral blade 1-2 provided on the outer surface of the main body 1-1 with the required spiral pitch, and the small diameter shaft 1-10 of the upper part of the main body 1-1 is deiced. While being axially supported by a bearing 7 fitted into an axial bore of the pressure head 4 fixedly disposed in a state of being fitted into the upper end side of the cylinder 2, the small diameter shaft portion 1-11 of the lower end thereof fits into the axial bore of the support 8 described later. By being axially supported by the bearing 9, it is inserted into the shaft center in the ice making container 2 so that rotation is possible.

The small diameter shaft portion 1-11 at the lower end having the spline 10 is connected to the output shaft 12 of the drive motor by the spline joint 11, and rotates at a predetermined rotational speed (rpm) by the power from the output shaft 12 to make the ice making cylinder 2 This thin slice or plate-shaped thin sound X is shown in Fig. 2 while the ice layer growing by freezing on the inner circumferential surface of the film is peeled off in thin slices or plates by the ends of the spiral blades 1 and 2 parallel to the inner circumferential surface. As shown in the figure, it is piled up in the spiral space 13 between the upper and lower spiral blades 1-2 existing at a predetermined spiral pitch, and then scraped and transferred toward the upper pressure head 4 (see FIG. 2).

Then, in the present invention, the main body portion located approximately in the center between the upper and lower spiral blades 1-2 with the air releasing port 15 communicating with the air releasing hole 14 provided toward the upper end along the axis of the main body portion 1-1 of the auger 1 It can be installed on the outer periphery of 1-1.

The air vent 15 is scraped from the inner circumferential surface of the ice making machine 2 in a thin strip or plate shape, and the peeled sound X is piled up to be stacked in the spiral space 13 while being scraped and conveyed to the upper pressure head 4 to be removed. The air trapped in the spiral space 13 by X is gradually discharged to the outside through the air releasing hole 14 of the main body 1-1 shaft by lamination to the spiral space 13 of the thin sound X. On the upper half side, it is installed in communication with the air bleed hole 14 on the outer periphery of the main body 1-1 located approximately at the center between the upper and lower blades 1-2.

If the blade tip thickness of spiral blade 1-2 of Auger 1 is thin, the thinner side can reliably and easily peel off the ice layer from the inner circumferential surface of the bin 2 in a thin slice or plate shape. It is set to 1-3 mm.

That is, if the vertical blade tip thickness of spiral blade 1-2 is 1 mm or less, the strength against load that peels off the ice layer growing on the inner circumferential surface of ice making machine 2 is insufficient, and may be damaged in a short time. It is strongly pushed inward in the radial direction by the slowly growing ice layer by freezing. That is, due to excessive radial load in radial direction due to the growing ice layer, it is shaken at the rotation axis of Auger 1, or the ice layer is thinly sliced or plate-shaped from the inner circumferential surface of the ice making container 2. It is because there exists a possibility that it will become impossible to peel off.

The ice making container 2 is a stainless steel cylindrical tube which is vertically installed by bolting on the drive housing 16 via the support body 8 fixedly inserted at the lower side, and has an inlet 17 of the ice making water at the lower side. , The outlet 18 is provided, and the ice-making water is supplied from the inlet 17 so that the ice-making water is filled up to the predetermined level L in the ice making chamber 2 and the predetermined level L is kept constant. To be drained.

In addition, the upper side of the ice making chamber 2 has a compression passage 5 on the circumferential surface of which the cross-sectional area gradually decreases upwards, and the pressing head 4 having the tapered-shaped ice cutting portion 6 on the upper side is fixedly fixed by bolting or the like. It is installed and put into it, and the real sound X, which is pushed upward by the auger 1, is introduced into the compression passage 5 and is gradually compressed. Dehydration that removes most of the water is performed, and the ice column adjusted to a hard rod shape is continuously. This ice column hits the ice cut 6 at the top, resulting in an ice cube X cut into chips.

The refrigerant pipe 3 is wound in a spiral shape so as to be in close contact with the outer surface of the ice making container 2 and fixedly mounted by soldering. It is an evaporator that serves to cool down to the freezing point, and becomes a desirable metal pipe such as copper materials having high thermal conductivity, and is wound in a spiral shape on the outer circumference of the ice making bin 2, and a spiral gap between the ice making bin 2 along the spiral Is fixed to the ice tray 2 by soldering so that it is completely filled by the soldering material 19.

Incidentally, in this embodiment, this soldering is performed by so-called quenching, which is immersed in the furnace in which the molten soldering material is stored, and the soldering material 19 is rapidly introduced between the spirals to harden the gap completely. At the same time, the brazing material is adhered and hardened on the outer surface of the refrigerant pipe 3 so that the outer surface is surrounded by the solder film 20.

Next, the auger ice machine constructed as described above will be briefly described. As the thin blade is scraped off by the spiral blade 1-2 of the auger 1 from the inner circumferential surface of the ice maker 2, the upper and lower spiral blades 1-2 are peeled off. As shown in the enlarged view of FIG. 2, the upper side of the thin sound X stacked and stacked in the spiral space 13 between the guides is curved toward the main body portion 1-1 side of the oga 1 by the lower taper portion of the spiral blade 1-2. Ice powder is deposited on the lower side of the spiral space 13, and the air trapped in the spiral space 13 quickly escapes from the air outlet 15 opened in the main body 1-1 of the central portion thereof.

Therefore, the thin sound X, scraped off from the inner circumferential surface of the ice making container 2 and peeled off, is stacked and stacked in the spiral space 13 so as to block the upper side of the spiral space 13, and then scraped and transferred to the upper pressure head 4. In the process, it is possible to quickly and reliably withdraw air from spiral space 13. Accordingly, it is introduced into the compression passage 5 of the pressure head 4 and adjusted to a hard rod shape in which most of the water is removed by the compression dehydration in the passage 5, and is formed in the rod shape from the compression passage 5 to the ice cutting portion 6. There is no mixing of air into the pillars of ice that are pushed out. Therefore, high quality ice can be manufactured.

In the Auger-type ice maker of the present invention, the auger's spiral blade may be configured as described above to obtain the following effects.

The auger's main body of the auger is formed by the bottom taper of the spiral blade, which is stacked on the spiral space between the upper and lower spiral blades by scraping and peeling a thin piece or plate by the auger's spiral blade from the inner circumferential surface of the ice making machine. It is guided to be bent to the negative side, the ice powder is deposited on the lower side of the spiral space, the air trapped in the spiral space quickly escapes to the outside from the air escape port opening in the main body portion of the central portion.

Therefore, the ice layer scraped off from the inner circumferential surface of the ice making container in a thin strip or plate shape is stacked in this spiral space so as to prevent the upper side of the spiral space, and is stacked and stacked in the spiral space in the process of being scraped up by the upper pressure head and transported. The air can be taken out quickly and reliably.

Therefore, according to the present invention, an ice column is introduced into the compression passage of the pressure head and pushed toward the upper ice cutting portion from the compression passage while being adjusted to a hard rod shape in which most of the moisture is removed by compression dehydration in the passage. It is possible to produce high quality ice (ice chunks) of high quality without any air mixing.

In addition, according to the present invention, the ice layer can be scraped up and peeled off from the inner circumferential surface of the ice making machine in a thin piece or plate shape, and then scraped off by the pressurizing head, so that the ice layer is scraped off as in the conventional auger ice maker, and transferred to the pressurizing head. Compared to the conventional method, it is possible to provide an auger ice maker which produces high-quality ice (ice mass) while generating very few hard ice pillars in the state of being compressed (dehydrated) by the compression passage of the pressure head. .
