Description

Cooling water manufacturing equipment {Tank for making cooling water}

The present invention relates to a cooling water manufacturing apparatus, and more particularly, a means for installing an evaporator unit in water of cooling water stored in a cooling water tank, and can cool the cooling water to a temperature close to the freezing point, and in particular, the evaporator unit is installed. The cooling water tank is separated into a plurality of circulation chambers, and a plurality of stirrers for circulating water into the plurality of circulation chambers are installed so that the water circulating in the plurality of circulation chambers by each of the plurality of agitators flows quickly. Cooling water can be efficiently produced by supplying and circulating cooling water in the tank water tank to store agricultural products at a low temperature, and at the same time, cooling water at a low temperature in an aquatic reservoir for agricultural products that stores agricultural products at a low temperature. It relates to an improved cooling tank manufacturing apparatus for supplying and circulating the cooled water.

In general, companies that manufacture and process noodles-type foods such as tofu foods and udon noodles use cooling water to cool the prepared foods and then package them.

Conventionally, a cooling water production tank was constructed with a structure in which a refrigerant circulation pipe is piped in a zigzag shape inside the tank where water is stored.This is because the piping structure of the refrigerant circulation pipe installed inside the cooling water storage tank is very complex. It has been pointed out as a problem that it takes a lot of time and manpower, and that it takes a lot of manufacturing cost, and it has been pointed out that it is difficult to cool water to a temperature close to freezing point.

In order to solve the above problems, the applicant of the present invention has proposed a cooling water manufacturing apparatus of Utility Model Registration No. 20-0420043.

However, in order to install the primary cooling unit and the secondary cooling unit corresponding to the evaporator inside each of the pre-cooling tank and the main cooling tank, the above-described prior art directly enters the inside of the pre-cooling tank and the main cooling tank. Since it must be installed by assembling the support frame body and multiple cooling pipes, it took a lot of time and effort to install the primary and secondary cooling units inside the pre-cooling tank and main cooling tank described above, as well as the inside of the tank. It has been pointed out as a problem that it is very difficult and difficult to install piping in a confined space.

In order to solve all the problems that appear in the prior art (No. 20-0420043) as described above, the applicant of the present invention has proposed a cooling water manufacturing apparatus of Patent Publication No. 10-2014-0038609.

However, in the prior art disclosed in the above-described published patent publication, since the evaporator unit installed in a state immersed in water stored in the cooling water tank directly cools the water, it is possible to cool the water to a temperature close to the freezing point. Because the stirring operation of the underwater agitator installed at the bottom of the cooling water tank cannot circulate the entire water stored in the cooling water tank at the same flow rate, the water in the area directly affected by the rotating blades of the above water agitator The water flows quickly, but in the area less affected by the agitator, the water flows slowly or becomes stagnant.

Therefore, in the prior art described in the above publication, the water in the area close to the evaporator unit is directly cooled to a temperature close to the freezing point because the cooling effect of the evaporator unit acts directly. The water in the area is cooled slowly because the cooling effect of the evaporator unit does not work properly. Also, the water in the area directly affected by the rotating blades of the underwater agitator installed on the inner bottom of the cooling water tank is Although it flows quickly, the water in the area less affected by the rotor blades flows slowly or becomes stagnant. In this case, the water in the area where the cooling effect of the evaporator unit directly acts is directly affected by the rotating blades of the underwater agitator and quickly When flowing, water does not freeze even if the cooling effect of the evaporator unit acts directly, but unlike this, water in the area not affected by the rotating blades of the underwater stirrer is freeze while being directly affected by the cooling effect of the evaporator unit. The phenomenon will appear. Accordingly, water that is less affected by the underwater agitator among the water stored in the cooling water tank is supercooled and freezes occur. As a result, only some of the water stored in the cooling water tank circulates, and water not circulating slowly circulates or As a result, it is pointed out as a problem that the entire water stored in the cooling water tank cannot be uniformly cooled to a temperature close to the freezing point since it becomes stagnant.

Meanwhile, a prior art for storing agricultural products using cooling water by the applicant of the present invention has been proposed as Registered Patent Publication No. 10-1325917, but the above-described prior art (Patent Publication No. 10-2014-0038609) includes agricultural products. There is a lack of a configuration for circulating cooling water in the stored agricultural product low temperature storage tank, and thus the inability to circulate the cooling water in the agricultural product low temperature storage tank is emerging as a problem to be improved.

Registered Utility Model Publication No. 20-0420043 (2006. 07. 03. Announcement) Unexamined Patent Publication No. 10-2014-0038609 (announced on March 31, 2014) Registered Patent Publication No. 10-1325917 (announced on November 07, 2013)

The present invention was proposed by solving all the problems in the prior art as described above, and further improved to supply and circulate cooling water to the aquatic storage of agricultural products in which agricultural products are stored, and also to reduce the cooling water stored in the cooling water tank near the freezing point.
