As regards the practical implementation of the cold water unit: the cold water unit 2 comprises a second storage tank and a refrigerant unit, the second storage tank is used for storing cold water, the refrigerant unit is connected with the second storage tank and is used for reducing the temperature in the second storage tank, so the required cold water can be effectively obtained through the embodiment, in addition, the refrigerant unit comprises a compression unit, a condenser, an expansion valve and an evaporation unit, the evaporation unit absorbs heat from the outside, the evaporation unit generates a refrigeration effect on the second storage tank, the compression unit compresses refrigerant gas, high-pressure and high-temperature refrigerant gas flows into the condenser, the condenser can be connected with the first storage tank, and the first storage tank is heated by utilizing the heat energy emitted by the condenser; in any case, the cold water unit 2 referred to in this specification is used for providing cold water, regardless of the means.

The above description is an implementation of adjusting the temperature of two food machines at the same time, and when three food machines need to be adjusted at the same time, a third distribution manifold is further provided, and the implementation of the third distribution manifold is similar to the first distribution manifold and the second distribution manifold, so that the description is omitted here, and so on when more than four food machines need to be adjusted at the same time.
When the first food machine a and the second food machine B need hot water to adjust the temperature, the first valve assembly 33 and the third valve assembly 43 are opened, and the second valve assembly 34 and the fourth valve assembly 44 are closed, so that only one hot water unit 1 is used to adjust the temperature of the first food machine a and the second food machine B. When the first food machine a and the second food machine B need to be switched to cold water for temperature adjustment, the first valve assembly 33 and the third valve assembly 43 are closed, and the second valve assembly 34 and the fourth valve assembly 44 are opened, in this case, only one cold water unit 2 is used for temperature adjustment of the first food machine a and the second food machine B. Therefore, the greatest advantages of the invention are as follows: no matter how many food machines are, only one hot water unit 1 and one cold water unit 2 need to be built to supply each food machine for use, which not only has better competitiveness in terms of cost, but also can reduce the whole volume to solve the defects of the background technology.
In order to prevent the output temperatures of the cold water unit 2 and the hot water unit 1 from being too high or too low, the invention further comprises a temperature control unit, wherein the temperature control unit is provided with a first temperature interval set value of the first food machine A and a second temperature interval set value of the second food machine B, the temperature control unit obtains a heat source temperature control value according to the highest of the first temperature set value and the second temperature set value and a first control margin temperature value, and when the temperature of the first storage tank is higher than the heat source temperature control value, the hot water unit 1 is controlled to stop operating; in addition, the highest one of the first temperature set value and the second temperature set value is added with a restart heating margin temperature value to obtain a restart heating operation value, when the hot water unit 1 stops operating and the temperature of the first storage tank is lower than the restart heating margin temperature value, the hot water unit 1 is controlled to restart heating operation, and in addition, the restart heating margin temperature value is lower than the first control margin temperature value; the temperature control unit obtains a cold source temperature control value by subtracting a second control margin temperature value according to the lowest one of the first temperature set value and the second temperature set value, and controls the cold water unit 2 to stop operating when the temperature of the second storage tank is lower than the cold source temperature control value; in addition, the lowest of the first temperature set value and the second temperature set value is subtracted by a restart cooling margin temperature value to obtain a cold source restart cooling operation value, and when the cold water unit 2 stops operating and the temperature of the second storage tank is higher than the cold source restart cooling operation value, the cold water unit 2 is controlled to restart cooling operation.
For example, when the first temperature interval set value is 20 ℃ to 60 ℃ and the second temperature interval set value is 15 ℃ to 55 ℃, the heat source temperature control value is 60 ℃ plus the first control margin temperature value, and the restart heating operation value is 60 ℃ plus the restart heating margin temperature value, taking this specification as an example, the first control margin temperature value is preferably 10 ℃, the restart heating margin temperature value is preferably 5 ℃, so that the heat source temperature control value is 70 ℃ and the restart heating operation value is 65 ℃. For example, the cold source temperature control value is 15 ℃ minus the second control margin temperature value, the cold source restart cooling operation value is 15 ℃ minus the restart cooling margin temperature value, and taking this specification as an example, the second control margin temperature value is preferably 10 ℃, the restart cooling margin temperature value is preferably 5 ℃, so the cold source temperature control value is 5 ℃, and the cold source restart cooling operation value is 10 ℃. In addition, the invention can further utilize an automatic control principle, when the hot water temperature of the hot water unit 1 is 70 ℃, the hot water unit 1 is controlled to stop working, when the hot water temperature is reduced to 65 ℃, the hot water unit 1 is restarted, similarly, when the cold water temperature is 5 ℃, the cold water unit 2 stops working, when the cold water temperature is increased to more than 10 ℃, the cold water unit 2 is restarted, and therefore, the power consumption of the invention can be reduced through an automatic control function.
For example, the sticky food usually has a specific temperature-time adjustment curve, and generally, after the sticky food is heated to a certain temperature, the sticky food is kept at a uniform temperature for a moment, and then is cooled to another temperature, the uniform temperature is kept for a moment, and the temperature is slightly increased, so that the crystal structure and the surface gloss of the thick food can be changed, and the mouthfeel of the thick food can be improved. In order to make the food machine have better heating effect, the invention is further provided with a first temperature detector for detecting the temperature in the first food machine A, and is also provided with a second temperature detector for detecting the temperature in the second food machine. The temperature control unit is provided with a first temperature time curve of the first food machine A and a second temperature time curve of the second food machine B, and controls the opening and closing of the first valve body set 33 and the second valve body set 34 according to the detection result of the first temperature detector and the first temperature time curve; the temperature control unit controls the opening and closing of the third valve body set 43 and the fourth valve body set 44 according to the detection result of the second temperature detector and the second temperature-time curve.
For example, when it is determined that the temperature of the first food machine a needs to be raised currently according to the first temperature-time curve, the first valve assembly 33 is activated and the second valve assembly 34 is closed, so that the temperature in the first food machine a is raised to the temperature required by the first temperature-time curve; on the contrary, when it is determined that the temperature of the first food machine a needs to be lowered, the first valve set 33 is closed and the second valve set 34 is opened, so that the temperature in the first food machine a is lowered to the temperature required by the first temperature-time curve. The temperature adjustment of the second food machine B is analogized from the above, and is not described again.
In addition, the temperature required by the first food machine a can be adjusted by mixing cold water and hot water, for example, when the temperature of the first food machine a is adjusted at 40 degrees, because water at 40 degrees falls between the ranges of the temperatures of the water amounts provided by the hot water unit 1 and the cold water unit 2, the hot water provided by the hot water unit 1 and the cold water provided by the cold water unit 2 can be mixed at the output end of the first distribution manifold 3 by adjusting the opening degrees of the first valve body group 33 and the second valve body group 34, and then the mixed water is delivered to the first food machine a for temperature adjustment. Similarly, when the second food machine B has similar conditions, the description is omitted. Therefore, the overall temperature adjustment of the invention is more flexible, so as to meet various different temperatures required by various food machines.
Referring to fig. 1, next, referring to the embodiment of water quantity backflow, according to the present invention, a fifth valve body set 121 is preferably disposed on a communication path between the first backflow manifold 12 and the first food machine a, and a seventh valve body set 221 is preferably disposed on a communication path between the second backflow manifold 22 and the first food machine a; a sixth valve body group 122 is arranged on a communication path between the first return manifold 12 and the second food machine B, and an eighth valve body group 222 is arranged on a communication path between the second return manifold 22 and the second food machine B. Therefore, the present invention can control the amount of water flowing back to the hot water unit 1 or the cold water unit 2 by adjusting the fifth to eighth valve body groups 121, 122, 221, 222.
In order to prevent the temperature inside the hot water unit 1 or the cold water unit 2 from being greatly affected by the amount of water flowing back, the present invention further provides a third temperature detector and a fourth temperature detector, wherein the third temperature detector detects the temperature of the amount of water flowing through the first food machine a, the fourth temperature detector detects the temperature of the amount of water flowing through the second food machine B, and the temperature control unit controls the actuation of the fifth to eighth valve body sets 121, 122, 221, and 222 according to the detection results of the third temperature detector and the fourth temperature detector and in cooperation with the outlet water temperatures of the hot water unit 1 and the cold water unit 2.
For example, when the temperature control unit determines that the temperature of the water flowing through the first food machine a is closer to the temperature in the hot water unit 1, the fifth valve block set 121 is opened and the seventh valve block set 221 is closed, and similarly, when it determines that the temperature of the water flowing through the first food machine a is closer to the temperature in the cold water unit 2, the seventh valve block set 221 is opened and the fifth valve block set 121 is closed, so that the water flowing back to the hot water unit 1 or the cold water unit 2 does not change the inherent temperature greatly, thereby achieving the energy saving effect as a whole. Similarly, the operations of the sixth valve body group 122 and the eighth valve body group 222 are analogized as above, and are not described again. In addition, in order to avoid the shortage of the water in the hot water unit 1 or the cold water unit 2, the present invention may also adjust the operation of the fifth to eighth valve body groups 121, 221, 112, 222 according to the water amount in the hot water unit 1 or the cold water unit 2.
In addition, as shown in fig. 1, a cooling unit 5 is preferably disposed at a section of the output end of the second return manifold 22, where the cooling unit 5 may be, for example, a fan, a tower fan, a heat dissipation fin set, and so on, and all of the cooling units 5 having the cooling effect are referred to in this specification, and the work load of the cold water unit 2 is reduced by first reducing the temperature of the second return manifold. In addition, the first to eighth valve body sets 33, 34, 43, 44, 121, 122, 221, 222 preferably have two on-off valves 331, 332 and a flow valve 333, respectively, and the flow valve is disposed between the two on-off valves, so that when any one of the components of the present invention requires maintenance, the on-off valves can be selectively closed to prevent water from flowing therethrough.
The invention has the following advantages:
firstly, the temperature adjusting operation of a plurality of food machines and tools can be synchronously performed through the hot water unit 1 and the cold water unit 2, and the temperature adjusting operation of different foods and different heating ranges can be simultaneously performed.
Secondly, in the temperature adjusting process, the flow rate of the cold source and the heat source can be controlled, so that the temperature change is consistent with the specific temperature time characteristic curve of the food.
And thirdly, along with the temperature-time characteristic curve of the food, the food can be automatically heated, maintained and cooled, and the temperature and the time are controlled until the final temperature is reached.
And fourthly, energy sources are effectively utilized, so that energy sources can be saved, and the requirement change of the temperature of the matched food can be quickly regulated and controlled.
In summary, the present application is consistent with the principles defined by the patent laws, and the following descriptions are only illustrative of the preferred embodiments of the present invention, and the scope of the present application is defined by the claims.
