Description

The present invention relates to an auger type ice making machine, and more particularly to an auger-type ice making machine which is improved so as to reliably produce ice pieces having desired hardness and size.

(B) Conventional technology Conventionally, in this type of ice making machine, in a cooling cylinder, ice shaved by an auger is compressed by a plurality of ice compression passages provided at an upper portion thereof to form ice pieces. I have. A specific conventional example is disclosed in Japanese Utility Model Laid-Open No. 54-134954. According to the publication, a spiral blade is provided inside the cooling cylinder 10.
A pressing head 30 having a rotating shaft 18 (that is, an ice-breaking auger) provided with 16 and having a compression passage 32 formed at the upper end of the cooling cylinder 10 for compressing the ice-cut pieces guided by the spiral blade 16 is formed.
In the auger-type ice making machine equipped with, the compression passage 32 is formed by alternately arranged thick and thin projections 34a, 34b, and the lower end of each projection 34a, 34b has a tapered blade 3.
6,38.

FIG. 4 is an external view showing the configuration of the conventional pressing head, and FIG. 5 is an explanatory view showing a pattern of ice compression performed by the pressing head. The pressing head has a function of rotatably supporting the upper part of the rotary shaft of the helical blade. Therefore, in the present specification, the pressing head will be referred to as an upper bearing and the helical blade will be referred to as an ice shaving auger. First, first projecting pieces 2 are provided at equal intervals on the peripheral surface of the upper bearing 1 in FIG. A plurality of ice passages 3, 3,... Are formed between the projection pieces 2 therebetween. The protruding piece 2 is relatively thick and has a tapered blade 4 at the lower portion. Therefore, this first projection piece
The first and second tapered blade surfaces 4A, 4A opposing each other are the first.
Is formed. On the other hand, this first projection piece
The second protruding pieces 6, 6,... Protrude in the middle of the ice passage 3 where the straight surfaces 4B, 4B of 2, 2,. Second
The projection piece 6 is thinner and shorter than the first projection piece 2. Moreover, the lower portion also has tapered blades 7, 7,.... Therefore, a part of the straight surfaces 4B, 4B of the first protrusions 2, 2,... And the second protrusions 6, 6,.
The second ice compressing section 8,
8 (see FIG. 5) is formed, and the tip of the ice passage 3 is divided into two portions so as to form an ice shaping passage in which the straight surfaces 4B and 7B of the projecting pieces 2 and 6 face each other. Reference numeral 10 denotes a fixing screw mounting hole for fixing the upper bearing 1 to the cooling cylinder, which is formed in the thick first protrusion 2.

By the way, due to the above-mentioned prior art (Japanese Utility Model Application Laid-Open No. 54-134954) and the structure of the upper bearing 1 shown in FIG. 4, the ice is compressed twice to obtain relatively hard ice. The reason will be described with reference to FIG. That is, the ice shavings moved in the cooling cylinder by the ice shaving auger are first divided at the cutting edges of the tapered blades 4 of the first projecting pieces 2, 2,. It enters the compression parts 5,5… and the tapered blades 4,4…
The first ice compression is performed along the blade surfaces 4A, 4A. The ice mass rising while being compressed is then divided by the cutting edge of the second protruding piece 6 to have a predetermined size, and each of the divided ice masses enters the ice shaping passage thereabove. That is, this second
The projections 6 also serve to cut ice pieces which are initially compressed into two pieces. The entry of the separated ice block is performed along the blade surface 7A of the tapered blade portion 7 of the second projection piece 6, 6,..., And this portion, that is, the second ice compression portion 8, 8
Then, the second compression of ice pieces is performed. In this way, as the ice compression is gradually performed and further proceeds, the separated ice blocks are subjected to a shaping process at the opposing straight surfaces 4B and 7B thereon, cut by the azide data provided at the upper portion, and are cut to an appropriate size. And stored in an ice storage.

That is, the first compression is the area indicated by the diagonally downward slash, while the second compression is the area indicated by the diagonally downward slash,
In the region where the two intersect, the first and second compressions are proceeding simultaneously. In any case, double ice compression is performed in the conventional structure.

(C) Problems to be Solved by the Invention However, in the conventional device described in the above-mentioned publication, the second projecting piece that divides the ice piece into a predetermined size is an ice piece compressing passage composed of the first projecting pieces. , Ice pieces are compressed twice as described above, and the resulting ice pieces become harder than normal flake ice. Therefore, when slightly soft flake ice of a predetermined size is desired, it cannot be provided. Further, since the ice compression is performed twice, the resistance received from the ice compression passage is increased, and smooth ice production is hindered, and the amount of ice produced per day is reduced, which is not suitable for mass production.

An object of the present invention is to provide an auger-type ice maker which has been made in view of the above points and which can surely produce ice pieces having desired hardness and size.

(D) Means for Solving the Problems According to the present invention, ice growing on the inner wall of a cooling cylinder is scraped by rotating an auger for ice shaving provided in the cylinder and is sent upward, and the ice chips are removed from the ice. In an auger-type ice making machine that guides and compresses a plurality of ice passages formed on a peripheral surface of an upper rotating shaft of the auger provided at an upper part of a cooling cylinder to produce ice pieces, a plurality of ice passages are provided on a peripheral surface of the upper rotating shaft. The ice passage is formed by projecting a first projection piece, and an ice compression portion is formed by an opposing tapered surface provided below each of the projection pieces.
A second projection is provided in an area above the upper end of the projection to separate compressed ice blocks pushed out from the ice passages.

(E) Operation The ice chips scraped by the auger are sent upward,
When the ice enters the ice passage formed by the projection piece and rises along the tapered surface formed at the lower portion of the projection piece, ice compression is performed.

Ice compaction is performed only once, and the resulting ice mass is soft. In this way, the ice block further moves upward, after being pushed out of the upper end of the ice passage after ice shaping, is divided by the second projection piece located ahead of the ice block, and becomes several ice pieces. In this way, a soft ice piece having a desired size can be produced. In the ice making process, the ice is compressed only once, so that there is little resistance due to the passage of the ice pieces, the transition is smooth, and a large amount of ice can be continuously made.

(F) Example Hereinafter, an example of the present invention will be described with reference to the drawings.

First, an outline of an auger type ice making machine embodying the present invention will be described with reference to FIG. Note that the same or equivalent components as those in the related art shown in FIGS. 4 and 5 are denoted by the same reference numerals. Reference numeral 15 denotes a cooling cylinder in which a refrigeration evaporating pipe 16 is wound around the outer surface, and the periphery thereof is surrounded by a heat insulating wall. Reference numeral 17 denotes a water supply pipe for supplying water into the cooling cylinder 15, which is supplied from a water tank 19 provided with a water level control sensor 18, and supplied with a water supply valve 20 by the water level control sensor 18.
Is opened and closed and replenished from a water pipe. 21 is an auger for ice cutting rotatably arranged inside the cooling cylinder 15, and 1 is an auger.
A plurality of ice passages 3 are formed in the outer periphery of the upper bearing that supports the upper rotating shaft 22A of the shaft 22 in the axial direction. 23 is a drive motor for transmitting rotation to the auger 1 via a speed reducer 24, 25 is a shooter provided in communication with the upper opening of the cooling cylinder 15 and having an ice discharge cylinder 27 on the side, and an ice compression passage 3. Temporarily accept the ice block sent from 3. Reference numeral 26 denotes an agitator connected to the upper rotating shaft 22A of the auger 21.

Next, the structure of the upper bearing 1 according to the present invention will be described with reference to FIG. 1 and FIG. In other words, the second
The projection 6 is an ice passage formed by the first projections 2,2.
Are not arranged in the inside of the first protruding pieces 2, 2 but are provided at positions above the upper ends of the first protruding pieces 2, 2. Thereby, the first
The ice passage 3 formed between the projecting pieces 2 is composed of an ice piece compressing section 30 facing the tapered blade surfaces 4A, 4A and an ice piece shaping section 31 facing the straight faces 4B, 4B. The ice shavings pushed up from the cooling cylinder 15 are subjected to ice compression only once and immediately sent to the ice shaping process. Therefore, the compressed ice block in the ice passage 3 is softer than before. Thus, the first projection 2,
When the second piece 6 comes out from the upper end of the second piece, the soft compressed ice block is divided into two pieces of ice blocks having substantially the same size. Here, the second protrusion 6 only acts to break the ice pieces, but does not have the second ice compressing action as in the prior art.

As described above, it is possible to generate ice pieces having a required size which is softer than the conventional one. Since there is only one ice piece compression unit 30, the resistance due to it is reduced compared to the conventional one,
Passing over the ice smoothly takes place. Therefore, a large amount of ice chips can be made, and the production capacity increases.

(G) Effects of the Invention As described above, according to the present invention, the plurality of first protrusions provided on the peripheral surface of the upper bearing form the ice piece compression portion, and the first piece of the ice piece compression portion is formed. Since the second projection piece is provided at the position to divide the compressed ice block coming out of the ice piece compression section into one or a plurality of pieces, the ice shaving pieces pushed up from the cooling cylinder are formed by the ice piece compression section. As a result of being compressed only once, it comes out softly and is divided, so that a soft piece of ice having a predetermined size can be formed. Since the ice is compressed only once and the resistance of the ice passage is considered to be small, the smooth passage of the ice pieces is ensured and the amount of ice making increases. As described above, an auger-type ice making machine that solves the conventional disadvantages at once is provided by a simple configuration in which a projection piece for separating ice pieces, which was conventionally in the ice piece compression passage, is installed at a position protruding upward therefrom. it can.
