Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for producing and supplying cooling water used in various food industries. BACKGROUND OF THE INVENTION [0002] Cooling water is used for the brewing water and water for sake brewing and the washing water for cut vegetables. This cooling water is produced by cooling by passing through a heat exchanger connected to a refrigeration apparatus.Specifically, a cooling path is constructed between the heat-insulating structure of a cold storage tank and the heat exchanger. The stored water in the cold storage tank is sequentially circulated and cooled, and the cooled stored water in the cold storage tank is supplied as cooling water for various food industries. In the cooling water production and supply system described above, even if the circulating water is cooled to 0 ° C. by the heat exchanger, the temperature of the water initially injected into the cooling tank is usually the outside temperature, and therefore the cooling water Even if the cooling water is stored in the cold storage tank by operating the supply system, considering the economic effect,
The temperature of the cooling water stored in the cold storage tank is limited to 2 ° C. [0004] Cooling water used in various food industries is desirably at a water temperature close to 0 ° C, at which the viable number of various bacteria is drastically reduced. For example, in sake brewing, desired fermentation progress can be easily achieved, and in cut vegetables, it is effective to maintain freshness. However, in the above-mentioned conventional system, 2 ° C. is normal as described above, and it is not economically feasible or difficult to obtain cooling water at 0 ° C. without changing the system. Even if it is assumed that a water temperature of 0 ° C. is possible,
Partial freezing is caused by fine solids mixed into the first injection water. Accordingly, the present invention proposes a novel system capable of supplying 0 ° C. cooling water. [0007] A cooling water supply system according to the present invention comprises a cooling circuit having a filter and a circulation pump interposed between an adiabatic cooling tank (primary tank) and a cooling device. In addition, a discharge three-way valve is interposed in the circulation path, a discharge pipe is connected to a cooling water storage tank (secondary tank) with a cooling mechanism, and cooling water is supplied from the storage tank. Things. [0008] Water is poured into the primary tank, the water is circulated through a circulation path, cooled to a predetermined temperature (2 ° C), and stored in the primary tank. Cooling water of 0 ° C. or less in the circulation path (because fine solids that become nuclei for freezing have been removed by passing through a filter, so that it does not freeze unless a shock is applied even at 0 ° C. or less) by switching the three-way on-off valve , And store it in a secondary tank. Since the secondary tank is provided with a cooling mechanism, the water temperature is maintained at 0 ° C. or less, and the stored 0 ° C. cooling water is supplied to a predetermined use location. Next, an embodiment of the present invention will be described. The cooling water supply system shown in the embodiment includes a primary cooling mechanism and a secondary cooling mechanism. [0010] The primary cooling mechanism has a circulation configuration,
A circulation pump 2, a filter 4, a cooling device 5, a circulation path 2 connected to a cold storage tank (primary tank) 1 having an insulating structure
It has a three-way valve 6 for removal. The primary tank 1 is provided with an appropriate water injection mechanism 11 and is connected to a circulation path 2 on the inlet and outlet sides. The circulating pump 3 is a power source for circulating water for a predetermined amount, and the filter 4 employs a high-performance filter capable of removing fine solids. The cooling device 5 includes a known refrigerator main body 51,
The heat exchanger 52 includes a heat medium whose temperature has been lowered by the refrigerator main body 51 and a heat exchanger 52 for exchanging heat with water. Of course, a structure may be employed in which the heat medium cooled by the main body 51 of the heat exchanger 52 is used as a cooling source of the heat exchanger as it is, or the high-pressure heat medium itself is released and decompressed in the heat exchanger to directly reduce the pressure. A structure that obtains a low temperature may be used. A circulating pump 2 and a filter 4 are connected and connected to the water outlet side of the primary tank 1 in order, and a water outlet side of the filter 4 is connected to a heat exchanger 5.
2 and connected. Further, on the water intake side of the heat exchanger 52, a flow path communicating the water discharge side of the heat exchanger 52 with the primary tank 1, and a flow path communicating the water discharge side of the heat exchanger 52 with a secondary tank 8 described later. The three-way valve 6 is connected to switch between the three-way switching, and the three-way valve 6 is connected to the primary tank 1 to form a circulation path. The secondary cooling mechanism comprises a cooling water storage tank (secondary tank) 8 provided with a small cooling device 7, and the small cooling device 7 winds a cooling coil around an outer peripheral portion of the secondary tank 8. This prevents the temperature of the cooling water in the secondary tank from rising. The secondary tank 8 is connected to a take-out pipe 9 on the switching side of the take-out three-way valve 6, and an on-off valve 8 is connected to the cooling water supply side.
1 and a supply pipe 82 is connected thereto. The water is once removed by the primary cooling mechanism.
Cooled down to about ° C, stored in the primary tank 1, taken out of the cooling circulating water from the middle of the primary cooling circulation, stored and stored by the secondary cooling mechanism, and supplied a predetermined (0 ° C) cooling water appropriately according to use. Like that. More specifically, first, the primary tank 1
, And is cooled by passing through the heat exchanger 52, and returned to the primary tank 1. Therefore, by circulating the water for an appropriate time, the first water at the outside air temperature can be cooled to a predetermined temperature (2 ° C.) and stored in the primary tank 1. The cooling water in the primary tank 1 contains fine solids in the supply water itself.
At a temperature of ℃, freezing occurs with the fine solids as nuclei. For this reason, even if the cooling water is cooled to 0 ° C. or less by the heat exchanger 52, the cooling water stored in the primary tank 1 is kept at about 2 ° C. Next, the water discharge side of the heat exchanger 52 and the secondary tank 8
And a three-way valve 6
Switch. The water passed through the heat exchanger 52 is 0
Even if the temperature is cooled to not more than 0 ° C., the fine solids which are the nucleus of the freezing are removed by passing through the filter 4. . Since the secondary tank 8 has a heat insulating structure and is provided with the small cooling device 7, it is maintained and stored at 0 ° C. Of course, the service water is appropriately supplied to the primary tank 1 corresponding to the storage of the cooling water in the secondary tank 8, and the three-way valve 6 is appropriately switched to store the desired cooling water. As described above, since the cooling water of 0 ° C. or lower is stored in the secondary tank 8, the on-off valve 81
Are released from the supply pipe 82 to be used for a predetermined application. Note that the specific structure of the cooling devices 5 and 7 and the structure for assembling them into the tank are arbitrarily determined. As described above, according to the present invention, a cooling circulation path including a filter and a circulation pump is provided between an adiabatic cooling tank (primary tank) and a cooling device.
A cooling water supply system in which a three-way extraction valve is interposed in the circulation path, an extraction pipe is connected to a cooling water storage tank with a cooling mechanism (secondary tank), and cooling water is supplied from the storage tank.
The cooling water having a water temperature of 0 ° C. or less can be stored in the secondary tank, and the stored cooling water at 0 ° C. can be used for a desired application.
