Description

The present invention relates to a rapid cooling shaved ice production apparatus using an ice layer forming rotary drum.

Patent Document 1 describes the basic principle of the present invention. The basic principle is that a water supply means for supplying water to a water receiving device, a rapid cooling means having a concentric long double cylinder, a refrigerant supplied from the rapid cooling means, and the refrigerant are used. An ice layer-forming rotating drum that forms a film-like ice layer on the outer peripheral surface while rotating the water supplied from the water supply means like a "water wheel" intersects the outer peripheral surface of the ice layer-forming rotating drum. It is composed of a cutting blade provided so as to continuously scrape off the film-like ice layer.

Therefore, the subject of the invention described in Patent Document 1 is that water can be supplied from above to the outer peripheral surface of the cooling drum via the water supply pipe 28b and the water supply receiver 28a to form a film-like ice layer, which is efficient. It is to provide a rapid cooling shaved ice production apparatus having a simple structure.

Then, the solution of the present invention substantially contacts the cooling drum 21 that forms an ice layer having a predetermined thickness on the outer peripheral surface while the outer peripheral surface is maintained at a temperature below the freezing point and rotates, and substantially contacts the outer peripheral surface of the cooling drum. The ice shaving blade 29 formed on the outer peripheral surface of the cooling drum, the water supply suit (receiver) 28a and the water supply suit (receiver) 28a in which the edges of both side surfaces and the front edge are substantially in contact with the outer peripheral surface of the cooling drum. It is characterized by including a water supply means 28 including a water supply suit 28a and a water supply pipe 28b for supplying water to a space formed by an outer peripheral surface of the cooling drum 21 (see FIG. 3). The reference numerals are those of Patent Document 1.

Although the invention of Patent Document 1 has an advantage that a film-like ice layer can be formed instantaneously and substantially evenly, it has the following problems.
(A) A cooling drum in which bearing members are attached to the left and right side walls of a vertically long housing, a cooling drum 21 is provided inside the housing via the bearing members, and an ice shaving blade 29 is provided in an inclined shape inside the housing. The cooling drum 21, the ice shaving blade 29, and the water supply means 28 are arranged in the vicinity of the upper side of the cooling drum 21 in order to supply water from above the outer peripheral surface of the 21. Etc. cannot be easily attached to the housing. Therefore, the production is troublesome. Moreover, the space portion of the front wall of the housing cannot be effectively utilized.
(B) For example, since a storage container for receiving "snow-like shaved ice" scraped by the ice shaving blade 29 is provided inside the housing, it is troublesome to put in and take out the storage container 30, and the entire device becomes large.
(C) Since the "snow-like shaved ice" falls into the storage container as it is, it accumulates in a specific place in the storage container. In addition, the storage container 30 cannot be manually or electrically moved to the desired position while the cooling drum 21 is rotating.
(D) The structure for preventing the gas rapidly vaporized in the internal space of the cooling drum 21 from leaking to the outside is not described. In addition, the compressor cannot be made powerful because there is no packing to maintain airtightness.
(E) In addition, there are no problems and configurations such as difficulty in controlling the water supply suit 28a so that the water does not overflow, and the use of soft and safe shaved ice water.

Patent Document 1: Japanese Unexamined Patent Publication No. 10-68564

The first object of the present invention is to form an ice layer by effectively utilizing the mounting space portion between the left and right protruding support portions provided on the front surface of the housing while taking advantage of the invention of Patent Document 1. Each member such as a rotary drum, a scraping blade, and a guide plate for shaved ice can be easily incorporated. As a result, the efficiency of manufacturing work and the miniaturization of the device are realized. At the same time, a container that receives the snow-like shaved ice that slides down from the shaved ice guide plate is arbitrarily placed in the space below the shaved ice guide plate on the front surface of the housing, and the position can be freely displaced by, for example, manually or using a turntable. It is possible to make it. Further, the vaporized gas injected into the internal space of the ice layer forming rotary drum and having lost the cooling temperature is prevented from leaking to the outside.

The second problem is to maintain sufficient "airtightness" so that the gas flowing in the internal space of the ice layer forming rotary drum does not easily leak to the outside even if the pressure of the compressor constituting the cooling means is increased. Is what you can do. Further, depending on the embodiment, the sealing material has excellent durability.
The third problem is to prevent the shaved ice water W flowing out from the introduction path having the on-off valve from "overflowing" or scattering from the water storage tray as much as possible. The fourth problem is to be able to produce "non-sticky (non-melting) fluffy" snow-like shaved ice using soft and safe shaved ice water.

In addition, ice layer formation that prevents the cooling heat of the ice layer formation rotary drum from escaping through the bearings, and even if the water storage tray is thin, the arc-shaped lower side of the ice layer formation rotary drum is always immersed in the shaved ice water. The purpose of preventing dust from adhering to the rotating drum, allowing the shallow water storage tray to be freely moved in and out, etc., is specified by the dependent term.

The rapid cooling shaved ice manufacturing apparatus of the present invention is provided horizontally in a mounting space portion between a housing having left and right protruding support portions and the protruding support portions via left and right bearing members, and is driven. The ice layer-forming rotating drum that rotates by the driving force of the motor and the ice layer-forming rotating drum that are horizontally arranged below the ice layer-forming rotating drum and are provided with a water supply unit in the housing through a water introduction path to "water for shaved ice". Is horizontally supported by the left and right protruding support portions so as to substantially contact the front side of the ice layer forming rotary drum, and the ice layer forming rotary drum The left and right protruding support portions so that the scraping blade for scraping the film-like ice layer formed on the outer peripheral surface and the "snow-like shaved ice" scraped by the scraping blade can be guided in a predetermined direction. On one side wall of the ice layer forming rotary drum, a tubular protrusion portion rotatably supported by one of the left and right bearing members is provided. The inner and outer elongated cylindrical tubes constituting the rapid cooling means are concentrically inserted into the tubular protrusions, and further formed on the outer peripheral surface of the outer elongated cylindrical tube and the tubular protrusions. A first sealing material is provided between the inner peripheral surface of the annular recess (claim 1). The effects of the invention will be described later.

In the above configuration, the second sealing material is arranged so as to be adjacent to the first sealing material in the axial direction of the elongated cylindrical tube, and one side surface of the second sealing material is the other side surface of the first sealing material. It is characterized in that it is crimped to a close contact state (claim 2). Even if the pressure of the compressor constituting the rapid cooling means is increased by this configuration, the "airtightness" can be sufficiently maintained so that the gas flowing in the internal space of the ice layer forming rotary drum does not leak to the outside.

Further, at least the first sealing material and the second sealing material are constituent members of the gland packing, and are pressed by a packing presser having a plurality of fixing tools screwed into the tubular protrusions so that the side walls facing each other are crimped to each other. (Claim 3). With this configuration, the degree of adhesion in the radial direction to the outer elongated cylindrical tube is increased, and the sealing material is not easily damaged, so that the durability of the device can be maintained.

Further, the water introduction path is provided with either an automatic or manual opening / closing valve, and a flow rate control member is connected to the opening / closing valve toward the water storage tray, and the opening at the upper end of the flow rate control member is large. On the other hand, the control opening at the lower end has a diameter smaller than that of the opening so that the water for shaved ice can flow into the water storage tray little by little (claim 4).

With this configuration, the amount of "shaved ice water" flowing out of the flow control member can be made to substantially correspond to the thickness and amount of the film-like ice layer formed on the outer peripheral surface of the ice layer forming rotary drum. In addition, the shaved ice water flowing out of the introduction path having the on-off valve can be prevented from "overflowing" or splashing from the water storage tray as much as possible.

In addition, the water supply section of the housing temporarily stores "shaved ice water" that has been softened with an ion exchange resin and from which germs have been removed by the filtration treatment section, and the water supply section has an open / close valve. The water introduction path is connected (claim 5). With this configuration, it is possible to produce fluffy snow-like shaved ice that is "delicious and safe" and does not melt immediately.

Further, the water storage tray having an upper end opening is characterized by having a flat portion for receiving "water for shaved ice" and a shallow recess continuous with the flat portion (claim 6). With this configuration, the lower part of the ice layer forming rotary drum can always touch the "shaved ice water" that has flowed into the shallow recess like a water wheel. In addition, even if the storage tray is made thin, the arc-shaped lower side of the ice layer forming rotary drum can always be submerged in the shaved ice water.

Further, the left and right bearing members are formed into a tubular body having a flange portion by using a synthetic resin material (claim 7). With this configuration, the heat of the ice layer forming rotary drum can be prevented from escaping through the bearing.

Further, the mounting space portion of the protruding support portion is provided with a cover that covers the exposed outer peripheral surface of the ice layer forming rotary drum and the scraping blade (claim 8). With this configuration, it is possible to prevent dust from adhering to the ice layer forming rotary drum.

Further, the outer elongated cylindrical tube injects the refrigerant pressure-fed from the compressor housed in the housing into the internal space of the ice layer forming rotating drum through a small injection hole in a vaporized state. The elongated cylindrical tube inside is characterized in that the vaporized gas that has been injected into the internal space and has lost the cooling temperature is received through the suction port and returned to the compressor housed in the housing. (Claim 9). With this configuration, the refrigerant can be effectively used.

The present invention can take advantage of the basic principles and the invention described in Patent Document 1. Then, by effectively utilizing the mounting space between the left and right protruding support portions provided on the front surface of the housing, each member such as the ice layer forming rotary drum, the scraping blade, and the shaved ice guide plate can be easily used. It can be attached to the left and right protruding supports. As a result, it is possible to improve the efficiency of manufacturing work and reduce the size of the device. At the same time, a container that receives the snow-like shaved ice that slides down from the shaved ice guide plate is arbitrarily placed in the space below the shaved ice guide plate on the front surface of the housing, and the position is freely displaced, for example, manually or by using a turntable. be able to. Further, it is possible to prevent the vaporized gas injected into the internal space of the ice layer forming rotary drum and having lost the cooling temperature from leaking to the outside. Depending on the embodiment, since the shaved ice water W is used, it is possible to produce a fluffy snow-like shaved ice that is "delicious and safe" and does not melt immediately.

The outer elongated cylindrical tube 29 sends the refrigerant pumped from the compressor 12 housed in the housing via the heat exchange means 13 to the ice layer forming rotary drum 5 via one or a plurality of small injection holes 29a. The elongated cylindrical tube 28 injects into the internal space in a vaporized state, while the elongated cylindrical tube 28 receives the vaporized gas injected into the internal space and has lost the cooling temperature through one or more suction ports 28a.

Next, FIG. 15 is a schematic explanatory view of the rapid cooling means 11 that is cyclically connected to the layer-forming rotating drum 5. In FIG. 15, reference numeral 12 denotes a compressor that is installed in the first storage portion 2 of the housing and that compresses the refrigerant. The compressor 12 has, for example, a tank body, a condenser for condensing the compressed refrigerant, a condenser fan for discharging the heat generated by the condenser during condensation, an expansion valve, and the like.

Reference numeral 13 denotes a heat exchange means that is arranged in the first storage portion 2 so as to be adjacent to the compressor 12 and is connected to the compressor 12 via one of the refrigerant supply pipes 33. The refrigerant heat-exchanged by the heat exchange means 13 is sent to the outer elongated cylindrical pipe 29 via the other refrigerant supply pipe 33 and the two-way joint 32. The refrigerant sent to the outer elongated cylindrical tube 29 is vigorously ejected into the internal space of the ice layer forming rotary drum 5 through the small injection hole 29a, whereby the outer peripheral surface of the ice layer forming rotating drum 5 is, for example, It is cooled to about -14 degrees. The vaporized gas, which is vigorously ejected into the internal space of the ice layer forming rotary drum 5 and has been deprived of the generated heat, enters the elongated cylindrical tube inside from the suction port 28a, and enters through the two-way joint 32 and the return pipe 34. It is cyclically returned to the compressor 12.

The type of the refrigerant is not particularly limited, and for example, a commonly used hydrocarbon-based refrigerant, carbon dioxide refrigerant, or the like can be appropriately selected and used. Further, as the compressor 12, since the gland packing 31 is used for one of the bearings 7 in the embodiment, a large (strong) compressor 12 can be used.

Finally, the scraping blade 47 and the guide plate 48 will be briefly described. The scraping blade 47 is horizontally supported by the left and right protruding support portions 3b of the housing 1 so as to substantially contact the front side of the ice layer forming rotary drum 5, and rotates on the outer peripheral surface of the ice layer forming rotating drum 5. The membranous ice layer 50 rapidly formed inside is scraped off. Here, "to make substantially contact" has a meaning including the case where they are physically slightly separated from each other. In the embodiment, the scraping blade 47 is located orthogonal to the outer peripheral surface so as to be located below the central axis of the ice layer forming rotary drum 5. It is preferable that the angle of the tip of the scraping blade 47 is appropriately set, such as slightly upward or / or slightly downward corresponding to the rotation direction of the ice layer forming rotary drum 5.

In the embodiment, the scraping blade 47 is positioned below the center line in the axial direction of the ice layer forming rotary drum 5 and on the front side of the outer peripheral surface of the ice layer forming rotating drum 5. Further, when the "snow-like shaved ice 50a" is scraped off, the ice layer forming rotating drum 5 rotates in the direction of the arrow as shown in FIG. 3, but when the film-like ice layer 50 is completely scraped off, the arrow It rotates in the opposite direction. Therefore, the control unit can control not only the rotation speed but also the rotation direction depending on the signal from the input unit.

As shown in FIG. 13, the guide plate 48 is preferably integrally provided on the surface of the scraping blade 47. Further, the guide plate 48 has a horizontally long rectangular opening 49 through which a shallow water storage tray 25 can be taken in and out.

The 48a is an inclined base plate having the opening 49 and formed in a slightly tapered shape toward the lower end, and the inclined base plate 48a is provided on the inner wall surface of the left and right protruding end portions 3b of the housing 1. It is fixed appropriately. 48b is a pair of left and right surrounding plates fixed to the left and right end portions of the inclined base plate 48a, and these surrounding plates 48b are bent so as to approach each other from the central portion to the lower end portion.

Therefore, for example, the guide plate 48 can freely put in and take out the shallow water storage tray 25 at the time of washing, and can also take the “snow-like shaved ice 50a” scraped off by the scraping blade 47 in a predetermined direction (accepting container). It is possible to guide to the opening of 10).

The present invention is used, for example, to produce "non-sticky (non-melting) fluffy" snow-like shaved ice for commercial use.
