Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an apparatus for producing salt water ice used for cooling fresh seafood to maintain its freshness.

BACKGROUND ART Conventionally, freshwater ice has been commonly used as ice for preserving the freshness of fresh seafood during transportation or while it is on standby.
However, the epidermis of seafood moves water in and out according to the principle of osmotic pressure by balancing internal and external pressure, so especially in the case of fresh seafood,
It is known that when this comes into contact with freshwater ice, the fresh water is absorbed into the body, promoting chemical changes and rapidly reducing freshness.

Therefore, in order to overcome this problem, methods such as interposing a plastic film between freshwater ice and seafood, sprinkling salt on seafood, and even spraying seawater on seafood are being carried out. There is.

Problems to be Solved by the Invention However, with the above-mentioned conventional means, freshness preservation is incomplete, and the work is extremely troublesome and requires a lot of manpower.

Therefore, various attempts have been made to produce saltwater ice, but conventional ice making machines have problems with uniform quality due to factors such as the difference in freezing point temperature and specific gravity between freshwater and saltwater, and corrosion of the icemaker by saltwater. It was extremely difficult to obtain 100% of salt water ice.

Therefore, the present invention provides an apparatus for producing salt water ice that can easily obtain high quality salt water ice that can be used as is to maintain the freshness of fresh seafood, and that has a compact structure and does not require a large installation space. The purpose is to

Means for Solving the Problems In order to achieve this object, the present invention provides an ice maker that produces ice flakes or powder from raw water, a salt supply machine that adds salt to the produced ice, and a salt supply machine that adds salt to the produced ice. A stirring freezing machine that stirs and mixes salt water and salt water in a cold atmosphere to produce salt water ice, and an ice storage box that stores the produced salt water ice are arranged one above the other in a frame.

Function According to such a configuration, ice produced from raw water (fresh water) by the ice maker is sent to the stirring freezing machine after salt is added by the salt supply machine. In this stirring freezing machine, ice and salt are stirred and mixed in a cold atmosphere to form a salt-containing layer on the outside of the freshwater ice in the center, and a surface layer of fresh water on the outside of this layer. Flake-like or granular salt water ice with an ice layer formed thereon is obtained. The resulting brine ice is sent to an ice storage for storage.

At this time, the ice maker, salt feeder, stirring icer, and ice storage are arranged one above the other within the frame, making the entire device compact and requiring only a small amount of installation space. . In addition, the transportation of ice making materials and manufactured brine ice from the ice maker to the salt supply machine, from the salt supply machine to the stirring ice machine, and from the stirring ice machine to the ice storage
This can be done by the action of gravity, and therefore no special conveyance device is required.

It is possible to produce ice flakes or granules from raw water. A sterilization activation device 3 is connected to the ice making machine 1 for supplying raw water to the ice making machine. This sterilization activation device 3 activates raw water, such as underground water or tap water, supplied from a raw water inlet 4 by inhaling a large amount of ozonized air into the raw water,
And it is stored temporarily. Note that if the quality of the raw water is good and no sterilization activation treatment is required, this device 3 can be omitted. In that case, all you need to do is install a water storage tank.

A vertical transfer path 5 connected to the ice maker 1 is provided below the ice maker 1, and a salt supply device 6 is connected to the transfer path 5.
This salt supply machine 6 supplies salt such as coarse salt to the ice produced by the ice making machine 1 and passed through the transfer path 5.

A horizontal stirring ice-freezing machine 7 connected to the transfer path 5 is provided below the transfer path 5. The stirrer icer 7 has a cooling jacket 8 on its outer surface, and is cooled by brine passing through the inside of the cooling jacket 8. Further, the stirring/freezing machine 7 is composed of a screw mixer, and the transfer path 5
The ice supplied from the ice and the salt added to the ice are stirred, and the ice and salt are mixed together to produce salt water ice.

A refrigerator 9, a brine tank 10, and a cooling pump 11 for cooling the brine to the cooling jacket 8 are disposed below the stirring/freezing machine 7. Ethylene glycol solution or the like is used as the brine.

Further, below the stirring freezing machine 7, an ice storage 12 is provided for storing the salt water ice produced by the stirring freezing machine. The ice storage 12 is made of a heat insulating material such as vacuum insulation material (VSI).

1 to 3 show a specific example of the construction of a salt water ice production apparatus based on the present invention. In these FIGS. 1 to 3, 13 is a frame, which is installed on a floor surface 14. The frame is 3 up and down
It has a multi-stage structure with supporting parts 15, 16, and 17 in stages.

The upper support part 15 has an ice maker unit 18 which includes the ice maker 1 shown in FIG. It is provided. 26 is a condenser unit for the refrigerator 2.

A stirrer and icer 7 is attached to the middle support section 16. At the top of the supply side of the stirring freezing machine 7,
The lower end of the salt addition unit 19 including the transfer path 5 and the salt supply machine 6 is connected. The upper end of this salt addition unit 19 passes through the upper supporting section 15 and is connected to the lower end of the ice maker unit 18.

The lower support section 17 includes a refrigerator 9 for brine, a brine tank 10 and a cooling pump 11.

The raw water supplied to the sterilization activation device 3 is subjected to sterilization treatment by mixing ozone-containing air there. The raw water that exits the sterilization activation device 3 is sent to the ice maker 1
The ice is sent to the ice cubes, where it is made into flakes or granules.

The ice is then dropped in the above-mentioned form into the transfer channel 5, into which coarse salt from the salt feeder 6 is added while moving downwards. The ice that has passed downward through the transfer path 5 is dropped into the supply side of the stirring/freezing machine 7.

The internal temperature of the stirrer freezing machine 7 is maintained at about -10°C by brine flowing through a cooling jacket 8. In this cooling state, ice and coarse salt are stirred,
After uniform mixing, flaky or granular brine ice is obtained.

The obtained salt water ice is sent to the discharge section 21 of the stirring freezing machine 7.
The ice is dropped into the ice storage 12 through the ice inlet 22. The ice is then stored in an ice storage 12 made of a material with excellent heat insulation properties such as a vacuum insulation material, and is taken out from the door 20 of the ice storage 12 for use.
