[Prior art]

 In order to maintain freshness of fresh products such as fish and shellfish during transportation and standby, fresh products are generally cooled using brine ice.

Conventionally, in order to produce salt water ice, a salt water ice producing apparatus comprising, for example, a drum type scraping ice maker and a salt water supplying apparatus for supplying salt water to the ice maker is used.

[0004] The salt water supply device includes a water tank, and the salt and raw water (fresh water) are supplied to the water tank, and the raw water and the salt are stirred to generate salt water. Then, the salt water is supplied to the ice maker by an appropriate pump.

[0005] In an ice maker, salt water is supplied into a hollow drum cooled to a temperature below the freezing point of salt water to form a thin film of salt water ice on the inner surface of the drum, and the salt water ice is set in the drum. The flakes of salted ice were obtained by scraping off the blades.

[0011]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The apparatus for producing salt water ice of the present invention includes a water tank (1) for storing raw water, an ice maker (3) connected to the water tub (1) via a water supply pipe (2), and an ice maker. An ice storage (4) for storing the ice generated by (3).

The water tank (1) is supplied with raw water (fresh water) from a water source (not shown).

A pump (13) is arranged in the water supply line (2) so as to supply the raw water stored in the water tank (1) to the ice maker (3). A mixer (5) is arranged upstream of the pump (13) in the water supply pipe (2), and an ozone generator (6) is connected to the mixer (5). A salt water supply device (7) is connected to the water supply line (2) downstream of the pump (13) via a salt water supply line (11). Although the detailed illustration of the salt water supply device (7) is omitted, salt and fresh water are supplied to the salt water supply device (7), and the supplied salt and fresh water are mixed by the stirring device (7a). High concentrations of salt water are produced. The concentration of the salt water generated by the salt water supply device (7) can be freely adjusted.

A salt water tank (8) for storing salt water is provided downstream of a connection between the water supply pipe (2) and the salt water supply pipe (11).

Further, a part of the raw water flowing through the water supply pipe (2) is placed in a water tank (upstream) downstream of the pump (13) and upstream of a connection between the water supply pipe (2) and the salt water supply pipe (11). A return line (12) for returning to (1) is provided. The return path (12) is provided with a ceramic filling machine (9) filled with porous electromagnetic wave-generating ceramic granules, and raw water passing through the ceramic filling machine (9) is returned to the water tank (1).

Although the detailed illustration of the ice maker (3) is omitted, the ice maker (3) is of a drum-type scraping type and has a refrigerator. By operating the refrigerator, the ice maker (3) is operated. Flake or granular salt water ice is generated from the salt water supplied to 3).

The ice storage (4) is connected to a cooling device (10), and the cooling device (10) generates cooling air at -5 ° C. or lower. A fan (15) is connected to the cooling device (10), and air cooled by being blown into the cooling device (10) by the fan (15) is blown into the ice storage (4) to store the ice. (4) The temperature inside is set to −5 ° C. or less.

In the brine ice producing apparatus having the above-described configuration, air containing low-concentration ozone (preferably about 0.08 to 0.05 ppm) generated by the ozone generator (6) is supplied to the mixer (5) in the raw water. Is blown into Then, the air and the raw water are mixed by a mixer (5) to generate a gas-liquid mixture, and various bacteria of the raw water are ozone sterilized. Then, the gas-liquid mixture is pressurized and stirred by the pump (13). In this way, the solubility of the ozone-containing air in the raw water is increased, and the dissolved oxygen and ozone concentrations in the raw water are increased. Furthermore, the action of ozone imparts a bactericidal effect to the raw water.

Part of the raw water in which the ozone-containing air is dissolved is returned to the water tank (1) through the ceramic filling machine (9). Raw water that has passed through the ceramic filling machine (9) has an increased gas-liquid contact ratio. As a result, in the raw water supplied again from the water tank (1), the dissolved oxygen in the raw water becomes supersaturated when the ozone-containing air is blown. In addition, the sterilization effect is imparted to the raw water by the electromagnetic waves (far infrared rays) irradiated by the ceramic itself.

The remaining raw water is mixed with the high-concentration salt water generated by the salt water supply device (7) to become salt water to be supplied to the ice maker (3). This salt water is stored in a salt water tank (8) as required, and then supplied to an ice maker (3).

In the ice maker (3), flake or granular salt water ice is produced, and the produced salt water ice is stored in the ice storage (4). At this time, since the temperature in the ice storage (4) is kept below -5 ° C, the salt water ice will not melt.

In the salt water ice obtained as described above, supersaturated oxygen and a small amount of ozone are contained in the ice. The released oxygen and a small amount of ozone are released from the saltwater ice, and sterilization of fresh products and growth of various bacteria are suppressed.

The ice maker used in the salt water ice producing apparatus of the present invention is not limited to the drum type scraping type ice maker.

[0025]

[Effect of the invention]

 According to the salt water ice producing apparatus of the present invention, since the ozone generator (6) is connected to the water supply line (2) upstream of the connection with the salt water supplying apparatus (7), supersaturated oxygen and a small amount of By containing ozone, it is possible to produce salt water ice free of various bacteria and having a high sterilizing effect.

When the ozone generator (6) is connected to a mixer (5) provided upstream of a connection with the salt water supply device (7) in the water supply pipe (2), ozone and raw water Are mixed to form a gas-liquid mixture, and various bacteria in raw water are efficiently ozone sterilized.

Further, a water supply pipe is provided downstream of a connection between the water supply pipe (2) and the ozone generator (6) and upstream of a connection between the water supply pipe (2) and the salt water supply device (7). If a return line (12) is provided to return a part of the water flowing through the channel (2) to the water tank (1), and a ceramic filling machine (9) is provided in the return line (12), raw water, ozone and When the ozone-containing air is blown, the dissolved oxygen in the raw water becomes supersaturated. In addition, the sterilization effect is imparted to the raw water by the electromagnetic waves (far infrared rays) emitted by the ceramic itself.
