Description

[Detailed Description of the Invention] The present invention provides an automatic continuous noodle boiling machine that is integrally equipped with a refrigeration device as a water supply source for cooling boiled noodles, and uses the refrigeration device as a cold-heat pump that serves as both a refrigeration machine and a heat pump. The present invention relates to a method and device for saving fuel in an automatic continuous noodle boiling machine, which makes it possible to recover and reuse heat and water that were wasted in the past as effectively as possible.

In conventional automatic continuous noodle boilers, raw udon noodles are generally boiled in boiling water heated by steam to a temperature of 100°C or higher, and then the boiled noodles are boiled in a cooling tank to improve the flavor and to prevent the growth of bacteria. Usually, they are placed in a container and washed with room-temperature water.

However, this type of conventional equipment uses room-temperature water for the heating boiler, which has the drawbacks of high fuel consumption and a long time required to start the boiling process. In the case of boiled noodles that are washed with water at room temperature, the temperature of the noodles after washing is relatively high, which may deteriorate the flavor of the product, and bacteria may easily grow, resulting in a lack of long-term storage. In addition, the heat content of the boiled eggs and the water after the cold water treatment are wasted, resulting in extremely low economic efficiency.

The present invention was newly devised in view of the above-mentioned circumstances, and includes a freezing device integrated into an automatic continuous noodle boiling machine.
The refrigeration equipment is used as a cold heat pump that doubles as a refrigerator and a heat pump, and while the refrigeration equipment continuously produces and supplies water for cooling boiled noodles at approximately 0°C, it also works as a heat pump to automatically preheat boiler water at room temperature to a high temperature. This method greatly improves the quality of boiled noodles and extends the shelf life of boiled noodles, while also recovering as effectively as possible the heat and water that was wasted in the past. It is an object of the present invention to provide a method and device for saving fuel in an automatic continuous noodle boiling machine, which can be reused and greatly save the thermal energy required for the automatic continuous noodle boiler.

Next, the operation of the present invention will be explained.

To start the boiling process, first, the required amount of water is supplied to each tank (boiling tank 1, boiled noodle cooling tank 4, freezing tank 9, heating tank 14, and hot water tank 16) and the boiler, and the boiler 2 is ignited to produce steam. It is fed to the indirect heating pipe 3 via the connecting pipe 2a, and the refrigeration device B is operated.

As described above, the temperature of the boiling water in the boiling tank 1 is the set temperature, for example, 100°C, and the water temperature in the boiling noodle cooling tank 4 is the set temperature, for example, 0°C.
5, the first endless belt 5 and the second endless belt 5 for transferring boiled noodles are reached.
The endless belt 6 is rotated to start the boiling work.

In this case, the boiled balls in a high temperature state transferred by the first endless belt 5 are transferred to the second endless belt 6 and are rapidly cooled with 0°C cold water while passing through the cooling tank 4. Boiled noodles are firm and have an excellent flavor, and since the noodles after cooling are discharged at a lower temperature (approximately 10°C) than when cooling with room temperature water, bacterial growth is significantly reduced and long-term storage is possible. You can get good quality products.

On the other hand, the water after the above cooling process absorbs the heat held by the boiled balls and reaches a high temperature (approximately 10 degrees Celsius).
This water is sucked up by the circulation pump 10a and returned to the freezing tank 9 via the return pipe 10, and then further lowered to cold water at 0°C by the endothermic action of the evaporator 7. Since the water is continuously circulated and supplied into the cooling tank 4 through the cooling tank 4, the water temperature in the cooling tank 4 is always maintained at a low temperature.

In addition, since the heat taken from the heat held by the boiled balls is absorbed by the evaporator 7 of the refrigeration cycle, the refrigerant in the evaporator 7, such as liquid ammonia, is vaporized at a low temperature and becomes ammonia gas. is pressurized by the compression pump 12, becomes high-temperature, high-pressure superheated ammonia gas, enters the condenser 8 installed in the heating tank 14 of the heated water production device B2, and heat exchange is performed within the heating tank 14. It becomes saturated ammonia gas and further becomes liquid ammonia, which reaches the evaporator 7 via the expansion valve 13.

Since this refrigeration cycle operates continuously, the temperature of the room-temperature water stored in the heating tank 14 is gradually increased to become high-temperature hot water (approximately 50° C.).

This hot water is stored in a hot water tank 16 via a connecting pipe 17, and is also supplied to the boiler 2 as preheated water by a water supply pump 18a.

Therefore, the time required to start the next boiling operation is significantly shortened.

The hot water stored in the hot water storage tank 16 can be used as water for cleaning equipment after work or as hot water for the boiling tank 1 by opening the heated water outlet valve 20 as needed. To make cleaning work of equipment in winter comfortable and easy, and to dry equipment quickly after cleaning even in summer, and to maintain its hygiene completely.

In summary, the present invention integrally incorporates a refrigeration device into an automatic continuous noodle boiling machine, uses the refrigeration device as a cold heat pump that also serves as a refrigerator and a heat pump, and uses approximately 0.5 oz of boiled noodle cooling water as the refrigeration machine. In addition to being able to continuously manufacture and supply boiler water as a heat pump, it can preheat and supply boiler water to a high temperature, thereby greatly improving the quality of boiled noodles and extending the shelf life of boiled noodles. The heat and water that was previously wasted can be recovered and reused as effectively as possible, and the thermal energy required for automatic continuous noodle boiling machines can be greatly saved, and the The time required to start boiling can be significantly shortened,
In addition, the preheated water can be used to clean the equipment and pour hot water into the boiling tank after the work is completed, providing extremely useful novel effects.
