<About overview>

First, an outline of the food cleaning system according to the present embodiment will be described with reference to FIGS. 1 and 2. As shown in FIG. 1, the food cleaning system SYS includes a cleaning water generating device 1 that generates cleaning water, and a cleaning device (food cleaning device) 2 that cleans food with the cleaning water supplied from the cleaning water generating device 1. And. The cleaning water generator 1 and the cleaning device 2 are controlled by the control device 3. These devices 1 to 3 are provided, for example, in one housing 70 as shown in FIG.

The washing water generating apparatus 1 mainly includes a water receiving unit 11, an electrolysis unit 12, a heating unit 13, and a washing water supply unit 15. The water receiving unit 11 receives tap water as raw water. The water receiving part 11 is implement | achieved by the valve | bulb connected with the water pipe, for example. The heating unit 13 generates high-temperature hot water by heating the tap water received by the water receiving unit 11. The water to be heated may be purified water after being purified, or may be soft water after being softened. The temperature of the hot water is desirably in the range of 45 ° C. to 52 ° C., for example, about 50 ° C.

The electrolysis unit 12 generates electrolyzed water (electrolytic hyponitrous water) using the tap water received by the water receiving unit 11. In addition, the tap water used for the production of electrolyzed water may also be purified water after being purified, or may be soft water after being softened. The electrolysis unit 12 has, for example, an electrolysis tank (not shown) of a diaphragm, and electrolyzes a diluted saline solution in the electrolysis tank. When the saline solution is electrolyzed, hypochlorous acid having sterilizing power and hydroxyl radical having high oxidizing power are generated. Electrolytic hypochlorous acid is water containing these hypochlorous acid and hydroxyl radicals.

The washing water supply unit 15 has a tap water supply unit 16, an electrolytic water supply unit 17, and a hot water supply unit 18 as its functions. The tap water supply unit 16 supplies the tap water received by the water receiving unit 11 to the cleaning device 2. That is, water that does not pass through the heating unit 13 (for example, room temperature) is supplied to the cleaning device 2. The electrolyzed water supply unit 17 supplies the electrolyzed water generated by the electrolysis unit 12 to the cleaning device 2. As will be described later, since the electrolyzed water generated in the electrolyzing unit 12 is usually high in concentration, the electrolyzed water diluted with tap water or warm water is supplied to the cleaning device 2. The hot water supply unit 18 supplies the tap water heated by passing through the heating unit 13, that is, hot water, to the cleaning device 2. In this manner, the cleaning water supply unit 15 can supply three types of water, ie, electrolytic water, tap water, and hot water, as cleaning water to the cleaning device 2. In the present embodiment, when “tap water” is simply referred to, it represents water having a temperature lower than that of hot water (hereinafter referred to as “low temperature water”).

Here, in the present embodiment, the electrolysis unit 12 generates electrolyzed water by further using hot water in order to enhance the electrolysis reaction in the electrolytic cell. The warm water used for the production of electrolyzed water typically includes sodium chloride. Since the electrolysis part 12 produces | generates electrolyzed water using a salt solution, it is desirable to give the above-mentioned heating part 13 also the function to heat a salt solution. In this case, the electrolysis unit 12 generates electrolyzed water using normal temperature tap water from the water receiving unit 11 and high-concentration and high-temperature saline obtained from the heating unit 13. The temperature of the electrolyzed water produced is, for example, a medium temperature of 15 ° C. to 35 ° C.

The cleaning apparatus 2 includes a cleaning water tank 20 that stores food as an object to be cleaned, a water supply unit 21 that supplies cleaning water into the cleaning water tank 20, and a drive system 22 that drives the cleaning water tank 20 and the like. The water supply unit 21 receives the cleaning water supplied from the cleaning water supply unit 15 of the cleaning water generator 1 and supplies the received cleaning water into the cleaning water tank 20. The drive system 22 is controlled by the control device 3. As shown in FIG. 2, the housing 70 is provided with a food inlet 71 and a food outlet 72 that communicate directly or indirectly with the washing water tank 20. The movement of the food between the food inlet 71 and the food outlet 72 and the washing water tank 20 may be performed by, for example, a conveyor (not shown).

As described above, the cleaning water tank 20 is supplied with three types of cleaning water from the cleaning water supply unit 15 of the cleaning water generator 1, tap water, electrolytic water, and hot water. Therefore, in the present embodiment, the cleaning of food in the cleaning device 2 can be selectively performed using three types of cleaning patterns including a tap water cleaning pattern, an electrolytic water cleaning pattern, and a hot water cleaning pattern. This tap water cleaning pattern may be read as a low temperature water cleaning pattern.

In addition, when the hardness of the tap water (raw water) received by the water receiving unit 11 is high, the raw water cleaning pattern and the soft water cleaning pattern may be included in the tap water cleaning pattern. The electrolyzed water cleaning pattern may include a first sterilization pattern using low-temperature electrolyzed water and a second sterilization pattern using electrolyzed water having a higher temperature. In this case, the temperature of the first sterilization pattern is, for example, the temperature of raw water or less. The temperature of the second sterilization pattern is, for example, about the same as warm water (50 ° C.). In the following description, the first sterilization pattern is referred to as “low-temperature sterilization pattern”, and the second sterilization pattern is referred to as “high-temperature sterilization pattern”.

The type of cleaning pattern of the cleaning device 2 can be selected by the user. Therefore, the food cleaning system SYS of the present embodiment further includes an operation unit 30 for receiving an instruction from the user. As shown in FIG. 2, the operation unit 30 is provided on an exposed surface (for example, an upper surface) of the housing 70 and includes, for example, a plurality of operation buttons. The operation unit 30 causes the user to select at least one of the three types of cleaning patterns. An instruction signal from the operation unit 30 is input to the control device 3. On the exposed surface of the housing 70, a display unit 32 for displaying various types of information such as a cleaning pattern name selected by the user may be further provided.

The control device 3 controls the cleaning water generating device 1 so that the cleaning water corresponding to the cleaning pattern selected by the operation unit 30 is supplied from the cleaning water supply unit 15 to the cleaning device 2. Further, the control device 3 controls the cleaning device 2 so that the food stored in the cleaning water tank 20 is cleaned with the cleaning pattern selected by the operation unit 30. In FIG. 1, signal lines are indicated by broken-line arrows.

The control device 3 may be a general computer, and includes an arithmetic processing unit that performs various arithmetic processes, a storage unit that stores various types of data and programs, and a time measuring unit that performs a timing operation. (Neither shown).

The salt water generation unit 132 also has a water tank (not shown) that stores the soft water from the water softening unit 103. Salt is appropriately supplied from the salt supply unit 133 to the water tank of the salt water generation unit 132, and salt water close to saturation is stored. For example, a water amount sensor is provided in the water tanks of the hot water generating unit 131 and the salt water generating unit 132 and may be controlled so as to store predetermined amounts of hot water and saline, respectively.

The heating of the soft water in the water tank of the hot water generating unit 131 and the heating of the salt water in the water tank of the salt water generating unit 132 may be realized by a common heater (not shown) or independent heating. It may be realized by a vessel (not shown).

The high-temperature saline generated by the saline generator 132 passes through the saline supply path 44 and is supplied to the electrolyzer 12. In the electrolysis unit 12, high-concentration electrolyzed water is generated by electrolyzing soft water and high-concentration saline that have flowed into the electrolytic cell.

3, the saline solution supply path 44 may have a branch path 45 that leads to the water softening unit 103. By passing the branch path 45 and supplying high-temperature saline to the water softening unit 103, calcium and magnesium adhering to the ion exchange resin can be removed. A three-way valve (not shown) as a switching unit is provided at a connection portion between the main route of the saline supply route 44 and the branch route 45. The three-way valve is opened by the control device 3 only when the saline solution needs to be supplied to the water softening unit 103. The supply of the saline solution to the water softening unit 103 may be performed periodically or according to the state of the ion exchange resin.

As described above, when the cleaning water generating apparatus 1 includes the purification unit 101 and the water softening unit 103, the cleaning water supply unit 15 is configured as follows, for example.

The opening and closing of the three-way valve 62 is controlled by the control device 3. When supplying soft water, the three-way valve 62 is closed, and when supplying electrolytic water, the three-way valve 62 is opened. When the three-way valve 62 is opened, high-concentration electrolyzed water is dripped into the soft water passing over the soft water path 53. Therefore, the path 53 a located on the downstream side of the three-way valve 62 of the soft water path 53 also functions as a part of the electrolyzed water supply path 56.

As described above, since the temperature of the electrolyzed water generated in the electrolysis unit 12 is intermediate, the cooling unit 104 is provided on the downstream side of the three-way valve 62 in the soft water path 53. The cooling unit 104 may be provided across both the soft water path 53 and the raw water path 52 so that the purified water passing through the raw water path 52 can also be cooled.

A three-way valve 63 serving as a switching unit is also provided at the connection between the hot water passage 54 and the hot water confluence passage 57a. The opening and closing of the three-way valve 63 is also controlled by the control device 3 in the same manner as the three-way valve 62. When supplying warm water, the three-way valve 63 is closed, and when supplying electrolytic water, the three-way valve 63 is opened. When the three-way valve 63 is opened, high-concentration electrolyzed water is dripped into the warm water passing over the warm water path 54. A path 54 a located on the downstream side of the three-way valve 63 in the hot water path 54 also functions as a part of the electrolyzed water supply path 57.

Although not shown in FIG. 3, the water supply unit 21 of the cleaning device 2 shown in FIG. 1 is connected to the end 52 a of the raw water path 52, the end 53 b of the soft water path 53, and the end 54 b of the hot water path 54.

When the soft water cleaning pattern of the tap water cleaning pattern is selected from the end 53b of the soft water path 53 to the water supply unit 21, low temperature soft water is supplied, and the low temperature sterilization pattern is selected from the electrolytic water cleaning pattern. In this case, low-temperature electrolyzed water is supplied. When the warm water cleaning pattern is selected from the end 54b of the warm water path 54 to the water supply unit 21, hot water is supplied, and when the high temperature sterilization pattern is selected from the electrolytic water cleaning pattern, Electrolyzed water is supplied.

The water supply unit 21 may be configured by a single water supply pipe that selectively supplies the cleaning water from the paths 52 to 54 to the cleaning water tank 20, or the cleaning water from the paths 52 to 54 respectively. It may be composed of three water supply pipes for supplying water.

In the cleaning tank 201, a (sanitization) cleaning operation with the above-described cleaning pattern is performed. Since the cleaning water supply path when performing the cleaning operation in the cleaning tank 201 is shown in FIG. 3, the cleaning water supply path to the cleaning tank 201 is shown by a broken line in FIG. 4.

In the 50 ° C. washing tank 202, the food is rinsed with warm water to restore the freshness of the food. Hot water is supplied to the 50 ° C. washing tank 202 via the hot water path 54 shown in FIG.

<About operation>

Subsequently, the operation of the food cleaning system according to the present embodiment, that is, the food cleaning method will be described. FIG. 5 is a flowchart showing the food cleaning process in the present embodiment. This food washing process is realized by the control device 3 (specifically, the arithmetic processing unit) reading and executing a program stored in the storage unit.

Referring to FIG. 5, when operation unit 30 receives an instruction from the user, control device 3 receives an instruction signal from operation unit 30 (step S2). In the present embodiment, for example, at this time (that is, before the cleaning in the cleaning apparatus 2 is started), not only the cleaning pattern in the sterilization cleaning process but also the presence / absence of the 50 ° C. cleaning process is selected. The control device 3 temporarily stores the instruction content received from the user in the storage unit.

The control device 3 first determines which of the tap water cleaning pattern, the electrolytic water cleaning pattern, and the hot water cleaning pattern has been selected as the cleaning pattern in the sterilization cleaning process (step S4). If it is determined that the tap water cleaning pattern has been selected, the process proceeds to step S6. If it is determined that the electrolyzed water cleaning pattern has been selected, the process proceeds to step S14. If it is determined that the hot water cleaning pattern has been selected, the process proceeds to step S22.

In step S6, the control device 3 determines whether water softening is necessary. Whether or not water softening is necessary is selected by a user, for example. In this case, the operation unit 30 may include an operation button for instructing the raw water cleaning pattern and an operation button for instructing the soft water cleaning pattern. Alternatively, once the tap water cleaning pattern is selected in step S4, the presence or absence of water softening may be selected.

When it is determined that water softening is unnecessary (NO in step S6), the control device 3 controls the cleaning water generating device 1 so as to supply raw water to the cleaning device 2 (step S8). Specifically, the control device 3 opens the valve of the water receiving unit 11 and controls the purified water to pass through the raw water path 52. As a result, the water purified by the purification unit 101 is supplied to the cleaning device 2.

On the other hand, if it is determined that water softening is necessary (YES in step S6), the control device 3 controls the cleaning water generating device 1 so as to supply soft water to the cleaning device 2 (step S10).

The tap water cleaning operation is performed in the cleaning tank 201 shown in FIG. When this process ends, the process proceeds to step S30.

In step S14, the control device 3 determines whether or not the electrolytic water needs to be cooled. Whether or not the electrolytic water needs to be cooled is selected by a user, for example. In this case, the operation unit 30 may include an operation button for instructing a low temperature sterilization pattern and an operation button for instructing a high temperature sterilization pattern. Alternatively, once the electrolyzed water cleaning pattern is selected in step S4, the presence or absence of cooling may be selected.

If it is determined that cooling of the electrolyzed water is necessary (YES in step S14), the control device 3 controls the cleaning water generating device 1 so as to supply low temperature electrolyzed water to the cleaning device 2 (step S16). . Specifically, the control device 3 opens the valve of the water receiving unit 11 and performs control so that the soft water passes through the soft water path 53. Further, by opening the three-way valve 62 of the soft water path 53, high-concentration electrolytic water generated by the electrolysis unit 12 is added to the soft water generated by the water softening unit 103. Although the electrolyzed water to be added is at an intermediate temperature, since the cooling unit 104 is provided on the soft water path 53, low-temperature electrolyzed water diluted with soft water is supplied to the cleaning device 2.

On the other hand, when it is determined that cooling of the electrolyzed water is unnecessary (NO in step S14), control device 3 controls cleaning water generating device 1 so as to supply high-temperature electrolyzed water to cleaning device 2 (step S14). S18). When a certain amount of hot water is stored in the hot water generating unit 131, the control device 3 opens a tank valve (not shown) of the hot water generating unit 131 and controls the hot water path 54 to pass the hot water. . In addition, by opening the three-way valve 63 of the hot water path 54, high-concentration electrolytic water generated by the electrolysis unit 12 is added to the hot water generated by the hot water generation unit 131. Although the electrolyzed water to be added is at a medium temperature, the electrolyzed water at a high temperature diluted with soft water is supplied to the cleaning device 2 by being added to the warm water passing through the hot water passage 54 like an infusion.

When low-temperature or high-temperature electrolytic water is supplied to the cleaning device 2, the control device 3 starts the electrolytic water cleaning operation of the cleaning device 2 (step S20). The electrolyzed water cleaning operation is performed in the cleaning tank 201 shown in FIG. When this process ends, the process proceeds to step S30.

In step S22, the control device 3 controls the cleaning water generating device 1 so as to supply hot water to the cleaning device 2. Specifically, the control device 3 opens a tank valve (not shown) of the hot water generating unit 131 and performs control so that the hot water passes through the hot water path 54. Moreover, the warm water produced | generated by the warm water production | generation part 131 is supplied to the washing | cleaning apparatus 2 by closing the three-way valve 63 of the warm water path | route 54. FIG.

When the hot water is supplied to the cleaning device 2, the control device 3 starts the warm water cleaning operation of the cleaning device 2 (step S24). The warm water cleaning operation is performed in the cleaning tank 201 shown in FIG. When this process ends, the process proceeds to step S36.

In step S30, the control device 3 determines whether or not a 50 ° C. washing step is necessary according to the instruction from the user received in step S4. If it is determined that the 50 ° C. washing step is unnecessary (NO in step S30), the process proceeds to step S36. On the other hand, when it is determined that washing at 50 ° C. is necessary (YES in step S30), the control device 3 controls the washing water generating device 1 so as to supply warm water to the washing device 2 (step S32). The process here is the same as the process of step S22 in the warm water cleaning pattern.

When the hot water is supplied to the cleaning device 2, the control device 3 starts the hot water rinsing operation of the food by the cleaning device 2 (step S34). The warm water rinsing operation is performed in the 50 ° C. washing tank 202 shown in FIG. When the hot water rinsing operation is finished, the process proceeds to step S36.

In step S36, in order to perform the cooling process, the control device 3 controls the cleaning water generation device 1 so as to supply, for example, soft water to the cleaning device 2. When the low temperature soft water is supplied, the control device 3 starts the cooling rinse operation of the cleaning device 2 (step S38). The cooling rinse operation is performed in the cooling tank 203 shown in FIG.

When the cooling rinse operation is finished, the control device 3 performs the dehydration operation of the cleaning device 2 (step S40). The dehydration operation is performed in the dehydration tank 204 shown in FIG. When the dehydration operation is finished, the food in the dehydration tank 204 (washing water tank 20) is sent to the food take-out port 72 shown in FIG.

As described above, according to the present embodiment, food can be washed with a plurality of types of washing water in the sterilization washing step. For this reason, when sterilizing and washing food with electrolyzed water, the food may have a smell of lime, but the user can select a warm water washing pattern or tap water washing pattern depending on the type of food. Trouble can be solved. Examples of the type of food that tends to have a smell of lime include mushrooms.

Moreover, in this embodiment, after the food in which the freshness has fallen, the food can be rinsed with warm water in the 50 ° C. washing tank 202 after washing in the washing tank 201. Therefore, according to the food cleaning system SYS of the present embodiment, the freshness of the food can be recovered. Moreover, even when washing with electrolytic water is performed in the washing tank 201, it is possible to reduce or remove the odor of the salt by rinsing the food with warm water.

Moreover, since the warm water heated by the warming unit 13 of the washing water generating apparatus 1 can be used not only for the first washing operation but also for freshness recovery, it is efficient.

Moreover, the cooling rinse operation is performed in the cooling tank 203 also about the foodstuff which does not go through the 50 degreeC washing tank 202. FIG. Therefore, even if the dust or the like floating in the cleaning water in the cleaning tank 201 adheres to the food again, the dust or the like attached to the food can be removed by the cooling rinse operation.

Further, in the present embodiment, the soft water that has passed through the water softening unit 103 passes through the electrolysis path 43, and the saline generated by the soft water and salt passes through the saline supply path 44. Therefore, it can suppress that the scale which generate | occur | produces with the hardness component of water adheres to the electrolytic cell of the electrolysis part 12. FIG.

Moreover, in this Embodiment, the warming part 13 has both the warm water production | generation part 131 and the salt solution production | generation part 132, and can heat a soft water and salt solution simultaneously. Therefore, the washing water generating apparatus 1 (including the food washing system SYS) can be downsized.

Moreover, in the electrolysis part 12, since electrolyzed water is produced | generated using the salt solution heated in the heating part 13, the reactivity of the ion in an electrolytic vessel can be improved. This eliminates the need to inject an electrolytic solution for promoting electrolysis. Moreover, the washing efficiency of food when washing food with an electrolyzed water washing pattern can be increased.

Moreover, the food washing system SYS as shown in FIG. 2 is installed so that it can be seen by consumers at restaurants and food stores, thereby giving consumers a sense of security for the food provided. In order to further improve the sense of security for food, a transparent window 73 (FIG. 2) may be provided in the housing 70 so that consumers can see the state in which the food is washed in the washing water tank 20. In addition, when each of the tanks 201 to 204 shown in FIG. 4 is provided individually, a window portion 73 may be provided for each tank. Thereby, since the consumer can visually recognize how the food is washed through a plurality of steps, the reliability of the food can also be improved.
<Modification>

Hereinafter, modifications of the food cleaning system SYS according to the present embodiment will be described.

In the present embodiment, the user is allowed to select whether to use the soft water cleaning pattern among the tap water cleaning patterns, but the control device 3 depends on the hardness of tap water received by the water receiving unit 11. Thus, it may be determined whether softening is necessary. In this case, a hardness sensor (not shown) for measuring the hardness of tap water is provided in the water supply path 41 between the water receiving unit 11 and the purification unit 101, for example. The control device 3 may determine that tap water needs to be softened when the hardness measured by the hardness sensor is equal to or greater than a predetermined value.

For example, the cooling unit 104 is provided in the soft water path 53 (path 53a downstream of the three-way valve 62) so that low temperature electrolyzed water of about 4 ° C. can be supplied to the cleaning device 2. However, the cooling unit 104 may be provided in the tap water merging path 56 a from the electrolysis unit 12 to the three-way valve 62. In this case, the cooled high concentration electrolyzed water is added to normal temperature soft water.

Further, in this embodiment, the sterilization cleaning is performed (selectively) by both the low-temperature electrolysis water and the high-temperature electrolysis water. However, the sterilization cleaning may be performed by only one of them. Good. Alternatively, when the cooling unit 104 is not provided in the tap water supply path 51, the temperature of the electrolyzed water supplied from the tap water supply path 51 may be an intermediate temperature.

In the present embodiment, the electrolyzed water is generated using the saline solution heated by the heating unit 13 and the soft water at room temperature, but this is not restrictive. For example, electrolyzed water may be generated using normal-temperature saline and warm water generated in the heating unit 13. Or you may produce | generate electrolyzed water only by the salt solution heated from the heating part 13 by adjusting the density | concentration of the salt solution produced | generated by the heating part 13. FIG. In the latter case, it is desirable that the temperature of the saline solution generated in the heating unit 13 is controlled to be an intermediate temperature. This is because if the water temperature in the electrolytic cell is a high temperature close to 50 ° C., hypochlorous acid may be decomposed.

Further, as described above, in the present embodiment, it is assumed that the raw water received by the water receiving unit 11 is contaminated and has a high hardness, but when the degree of contamination of the received raw water is low The purification unit 101 and the purified water receiving unit 102 may not be included. Moreover, when the hardness of raw | natural water is low, the water softening part 103 does not need to be included in the washing water production | generation apparatus 1. FIG.

In the present embodiment, the cooling step and the dehydration step are essential steps. However, the user may select whether or not these steps are also necessary. Further, instead of or in addition to the dehydration step, a drying step for drying food by blowing air may be added.

Further, in this embodiment, the user individually selects the cleaning pattern in the sterilization cleaning process and the presence or absence of the 50 ° C. cleaning process, but this is not restrictive. For example, the user may select one of a plurality of courses such as a careful course and a simple course. In this case, for example, information indicating the process to be performed, the cleaning time in each process, and the type of cleaning pattern in the sterilization cleaning process is stored in advance in the storage unit of the control device 3. That's fine. Then, the user can clean the food easily and with an appropriate cleaning process only by selecting a course.

In the present embodiment, the control device 3 controls both the cleaning water generation device 1 and the cleaning device 2, but a control device may be provided for each of the devices 1 and 2. In this case, the food washing process shown in FIG. 5 can be realized by transmitting and receiving data and signals between the control devices.

Further, in the present embodiment, the food cleaning system SYS provided with the cleaning water generation device 1 and the cleaning device 2 has been described, but only the cleaning water generation device 1 or only the cleaning device 2 may be provided.

In the former case, the cleaning water supply unit 15 of the cleaning water generator 1 may selectively supply (outflow) tap water, electrolytic water, and hot water to the outside of the cleaning device 2 and the like. In other words, the flowing water portion from which the washing water flows out may be constituted by one flowing water pipe or may be constituted by three flowing water pipes. In this case, the cleaning water generation device 1 may include a control device that performs cleaning water generation control and supply control among the control performed by the control device 3.

Also in the latter case, the cleaning device 2 may include a control device that controls the operation of food using a plurality of types of cleaning water among the controls performed by the control device 3.

In the above description, at least three types of (disinfecting) cleaning patterns include an electrolytic water cleaning pattern, a tap water cleaning pattern, and a warm water cleaning pattern. There may be one kind. That is, the types of cleaning water supplied from the cleaning water generating device 1 may be two types of electrolyzed water and tap water regardless of temperature. In this case, the (sterilization) cleaning pattern in the cleaning device 2 includes only two types of cleaning patterns, that is, an electrolytic water cleaning pattern and a tap water cleaning pattern. The tap water cleaning pattern here represents either one of a low temperature water cleaning pattern for cleaning food with low temperature water and a hot water cleaning pattern for cleaning food with hot water.

If this tap water cleaning pattern is a low temperature water cleaning pattern, the warm water generating unit 131 may not be included in the heating unit 13. Moreover, although it is desirable that the saline solution is heated, the heating unit 13 itself may not be included in the washing water generating apparatus 1.

The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
