In addition, the present invention can utilize the principle of automatic control to control the temperature of the hot water in the hot water unit 1 when the temperature is 70°C. Unit 1 stops working, and restarts the hot water unit 1 when the hot water temperature drops to 65°C. Similarly, when the cold water temperature is 5°C, the cold water unit 2 stops working, and when the cold water temperature rises to 10°C When above, restart the cold water unit 2, so that the power consumption of the present invention can be reduced through the automatic control function.

Since each food requires different heating temperatures, especially for the pursuit of delicious food, each food even has its own time-temperature curve. For example, viscous food usually has a specific temperature-time adjustment curve, usually heated to a certain temperature first After one temperature, maintain the uniform temperature for a while, then lower the temperature to another temperature, maintain the uniform temperature for a while, and then slightly increase the temperature, so as to change the crystallization structure and surface gloss of the thick food, and improve the taste. In order to allow the food machine to have a better heating effect, the present invention further provides a first temperature detector to detect the temperature in the first food machine A, and a second temperature detector to detect the temperature in the first food machine A. 2.

For example, according to the first temperature-time curve, it is judged that the temperature of the first food appliance A needs to be increased at present. At this time, the first valve body group 33 will be activated, and the second valve body group 34 will be closed, so that the first food product The temperature in the appliance A rises to meet the temperature required by the first temperature-time curve; otherwise, when it is judged that the first food appliance A needs to lower the temperature, the first valve body group 33 will be closed and the second valve body group 33 will be opened. The valve body group 34 is used to lower the temperature in the first food appliance A to the required temperature satisfying the first temperature-time curve. The temperature adjustment of the second food machine B is analogous to the above, and will not be repeated here.

In addition, the present invention can also adjust the required temperature of the first food machine A through the mixing of hot and cold water. Temperature, for example, when the temperature of the first food appliance A is preferably adjusted at 40°C, since the water at 40°C falls within the range of the water temperature provided by the hot water unit 1 and the cold water unit 2, at this time By adjusting the opening of the first valve body group 33 and the second valve body group 34, the hot water provided by the hot water unit 1 and the cold water provided by the cold water unit 2 can be distributed in the first distribution manifold 3 The output end is mixed, and then transported to the first food machine A for temperature regulation. In the same way, when the second food machine B has a similar situation, it will not be repeated by analogy.

For example, when the temperature control unit judges that the temperature of the water flowing through the first food appliance A is closer to the temperature in the hot water unit 1, it will open the fifth valve body group 121 and close the first food appliance A. The seven valve body group 221, similarly, when it is judged that the temperature of the water flowing through the first food appliance A is relatively close to the temperature in the cold water unit 2, the seventh valve body group 221 is opened and the fifth valve is closed Body group 121, so that the amount of water flowing back to the hot water unit 1 or the cold water unit 2 will not greatly change the inherent temperature, so that the overall energy saving effect is achieved.
