[0010] A waste oil recovery system incorporating a waste oil evaluation system and a waste oil evaluation method according to one embodiment of the present invention will now be described with reference to the accompanying drawings. This waste oil recovery system recovers waste oil stored in a customer's waste oil tank and evaluates the quality of the waste oil. In particular, this waste oil recovery system is configured to evaluate waste oil stored in a waste oil tank after one or more waste treatment processes based on the flow rate of each process and the deterioration and liquidity of the cooking oil discarded in each process. In this embodiment, the waste oil recovery system is assumed to be a waste oil tank installed in a building (e.g., a department store or a complex building) that houses multiple stores, such as fried food stores and restaurants, and each store in the building disposes of its cooking oil into a single waste oil tank (hereinafter referred to as the cooking oil disposal system).

[0011] Before describing the waste oil recovery system 1, we will first explain how cooking oil is disposed of in a building where the oil is collected. As shown in FIG. 1, a waste oil tank 16 is installed at the collection source. Each store in the building is equipped with one or more fryers 17. The waste oil tank 16 is connected to each fryer 17 via piping 18, and stores the cooking oil discarded from each fryer 17 as waste oil. In other words, one waste oil tank 16 is shared by multiple stores in this cooking oil disposal system. The waste oil recovery system 1 recovers and evaluates the waste oil stored in the waste oil tank 16. The fryer 17 is an example of a cooking appliance.

[0012] (Configuration of waste oil recovery system) The waste oil recovery system 1 includes a recovery vehicle 11, a mobile terminal 12 carried by a recovery operator aboard the recovery vehicle 11, a recovery management server 13 connected to the mobile terminal 12 via a network NW and managing the recovery operations performed by the recovery vehicle 11, and a plurality of flow meters 14 and a plurality of deterioration level sensors 15 installed on each flyer 17 of each store in the building where the oil is recovered. The recovery operator is the person who operates the recovery vehicle 11. In this embodiment, a tank truck equipped with a storage unit for storing waste oil is used as the recovery vehicle 11. The waste oil recovery system 1 is an example of a waste oil evaluation system that evaluates waste oil stored in a waste oil tank 16. The flow meter 14 is an example of a flow rate detection unit.

[0013] The plurality of flow meters 14 are disposed on the piping 18 between the waste oil tank 16 and each fryer 17, and detect the flow rate (waste amount) of cooking oil from each fryer 17 to the waste oil tank 16. Specifically, each flow meter 14 is disposed on a branch piping to which each fryer 17 is connected, and is configured to be able to individually detect the flow rate from each fryer 17. Each flow meter 14 is also connected to the collection management server 13 via the network NW, and transmits flow rate data consisting of the detected flow rate and the time of detection (year, month, day, hour, minute, second) to the collection management server 13. In this embodiment, each flow meter 14 stores the flow rate data as a log, and upon receiving an information request signal from the collection management server 13, transmits the stored flow rate data to the collection management server 13.

[0014] A plurality of deterioration level sensors 15 are installed in the oil tank of each fryer 17 and detect the deterioration level of the cooking oil in the oil tank of each fryer 17. The deterioration level sensors 15 detect, for example, TPM (polar compound content), PV (peroxide value), AV (acid value), CV (carbonyl value), AnV (anisidine value), iodine value, tocopherol content, viscosity, viscosity increase amount, color (coloring), transparency, amount of volatile components, and amount of smoke generated as the deterioration level. Each deterioration level sensor 15 is connected to the collection management server 13 via the network NW and transmits deterioration level data consisting of the detected deterioration level and the time of detection (year, month, day, hour, minute, and second) to the collection management server 13. In this embodiment, each deterioration level sensor 15 stores the deterioration level data as a log, and upon receiving an information request signal from the collection management server 13, transmits the stored deterioration level data to the collection management server 13.

[0015] 2, the collection management server 13 is, for example, an information processing device including a communication unit 21, a storage unit 22, and a control unit 23. The communication unit 21 communicates with the mobile terminal 12, the plurality of flow meters 14, and the plurality of deterioration level sensors 15 via the network NW.

[0016] The storage unit 22 is configured with, for example, a hard disk, and stores various data related to the management of collection operations. In this embodiment, the storage unit 22 has a collection date and time database 31, a flow rate database 32, a deterioration degree database 33, and a disposal processing database 34.

[0017] 3(a), the collection date and time database 31 stores the latest collection date and time of cooking oil for the waste oil tank 16. That is, the collection date and time database 31 stores the latest collection date and time of the waste oil tank 16 in association with the identification information of the waste oil tank 16. The latest collection date and time is recorded, for example, upon receiving a collection completion report from the mobile terminal 12.

[0018] 3(b), the flow rate database 32 is a database that stores flow rate data (flow rate and detection time) acquired from each flow meter 14. In detail, as shown in the figure, the flow rate database 32 stores the flow rate data acquired from each flow meter 14 in association with the identification information of the waste oil tank 16, fryer 17, and store corresponding to each flow meter 14.

[0019] 3(c), the deterioration level database 33 is a database that stores deterioration level data (deterioration level and detection time) acquired from each deterioration level sensor 15. In detail, as shown in the figure, the deterioration level database 33 stores the deterioration level data acquired from each deterioration level sensor 15 in association with identification information of the waste oil tank 16, fryer 17, and store corresponding to each deterioration level sensor 15.

[0020] 4, the waste treatment database 34 is a database that stores various information about the waste treatment of disposing of cooking oil from the fryer 17 to the waste oil tank 16. In this embodiment, the waste treatment database 34 stores the start time and end time of each waste treatment, the flow rate, deterioration level, liquidity level, and quality evaluation value of the cooking oil to be disposed of in each waste treatment, as well as identification information of the waste oil tank 16, fryer 17, and store that perform each waste treatment.

[0021] The control unit 23 is composed of a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), etc., and controls each unit of the collection management server 13. As shown in Fig. 2, the control unit 23 executes a predetermined program to function as a flow rate data acquisition unit 41, a deterioration level data acquisition unit 42, a waste treatment specification unit 43, a treatment flow rate determination unit 44, a treatment deterioration level determination unit 45, a treatment liquidity determination unit 46, a treatment evaluation value calculation unit 47, a waste oil evaluation unit 48, a purchase price calculation unit 49, and a schedule creation unit 50. The treatment deterioration level determination unit 45 and the treatment liquidity level determination unit 46 are examples of an edible oil determination unit.

[0022] The flow rate data acquiring unit 41 controls the communication unit 21 to acquire flow rate data from the flow meters 14. In this embodiment, the flow rate data acquiring unit 41 transmits an information request signal to the flow meters 14, receives the flow rate data transmitted from the flow meters 14 in response to the information request signal, and acquires the flow rate data. The flow rate data acquiring unit 41 also records the flow rate data acquired from each flow meter 14 in the flow rate database 32 in association with the identification information of the waste oil tank 16, fryer 17, and store corresponding to each flow meter 14.

[0023] The deterioration level data acquisition unit 42 controls the communication unit 21 to acquire deterioration level data from the deterioration level sensors 15. In this embodiment, the deterioration level data acquisition unit 42 transmits an information request signal to the deterioration level sensors 15, receives the deterioration level data transmitted from the deterioration level sensors 15 in response to the information request signal, and acquires the deterioration level data. The deterioration level data acquisition unit 42 also records the deterioration level data acquired from each deterioration level sensor 15 in the deterioration level database 33 in association with the identification information of the waste oil tank 16, fryer 17, and store corresponding to each deterioration level sensor 15.

[0024] The waste treatment specification unit 43 specifies the waste treatment of cooking oil from each fryer 17 to the waste oil tank 16 based on the flow rate data of each flow meter 14 stored in the flow rate database 32. Specifically, each section in the flow rate data where the flow rate continues to be equal to or greater than a certain amount is specified as one waste treatment. Then, the waste treatment specification unit 43 records, in the waste treatment database 34, the start date and time and the end date and time of each specified waste treatment, as well as identification information of the waste oil tank 16, fryer 17, and store that perform each waste treatment, in association with each identified waste treatment.

[0025] The treatment flow rate determination unit 44 determines the flow rate (waste amount) of cooking oil in each waste treatment based on the flow rate data of each flow meter 14 stored in the flow rate database 32 and the start date and time and end date and time of each waste treatment recorded in the waste treatment database 34. For example, the treatment flow rate determination unit 44 calculates the flow rate of cooking oil in the waste treatment by extracting and integrating the flow rates detected between the start date and time and the end date and time of the waste treatment from the flow rate data of each flow meter 14. The treatment flow rate determination unit 44 also records the determined flow rate of each waste treatment in the waste treatment database 34.

[0026] The process deterioration degree determination unit 45 determines the deterioration degree of the cooking oil to be disposed of in each waste treatment process based on the deterioration degree data stored in the deterioration degree database 33 and the start date and time of each waste treatment process recorded in the waste treatment database 34. For example, the process deterioration degree determination unit 45 extracts the deterioration degree of the cooking oil at the start date and time of each waste treatment process from the deterioration degree data of each deterioration degree sensor 15, and determines the extracted deterioration degree as the deterioration degree of the cooking oil to be disposed of in each waste treatment process. The process deterioration degree determination unit 45 also records the determined deterioration degree of each waste treatment process in the waste treatment database 34.

[0027] The processed liquidity determination unit 46 determines the SFI value of the edible oil to be discarded in each disposal process. For example, the brand of edible oil to be discarded in each disposal process is identified based on ordering information and delivery information for the edible oil, and the SFI value of the edible oil is obtained from the identified brand based on ingredient information provided by the manufacturer. The processed liquidity determination unit 46 also records the determined SFI value of each disposal process in the disposal process database 34. The SFI value is an example of liquidity. In this embodiment, the SFI value is used as the liquidity, but the iodine value, constituent fatty acid composition, melting point, or softening point may also be used as the liquidity. That is, the liquidity is determined by using any one of the SFI value, iodine value, constituent fatty acid composition, melting point, and softening point.

[0028] The treatment evaluation value calculation unit 47 calculates the quality evaluation value of the edible oil to be disposed of by each waste treatment based on the deterioration level and SFI value of each waste treatment stored in the waste treatment database 34. For example, the quality (properties) of waste oil is evaluated as better the higher the SFI value and worse the higher the deterioration level, so the value obtained by dividing the SFI value by the deterioration level is used as the quality evaluation value of the edible oil for each waste treatment.

[0029] The waste oil evaluation unit 48 evaluates the quality of the waste oil currently stored in the waste oil tank 16 based on the flow rate and quality evaluation value of each waste treatment stored in the waste treatment database 34. For example, it extracts one or more waste treatments performed on the waste oil tank 16 from the latest collection date and time to the present, multiplies the flow rate and quality evaluation value for each of the extracted one or more waste treatments, and then divides the sum of these multiplied values ​​by the total flow rate of the one or more waste treatments to calculate the quality evaluation value of the waste oil. Note that in this embodiment, the quality of the waste oil stored in the waste oil tank 16 through waste treatments from multiple fryers 17 is basically evaluated, so the quality of the waste oil is basically evaluated based on the flow rate and quality evaluation values ​​of the waste treatments from the multiple fryers 17.

[0030] The purchase price calculation unit 49 calculates the purchase price of the waste oil stored in the waste oil tank 16 based on the evaluation value evaluated by the waste oil evaluation unit 48 and the amount of waste oil stored in the waste oil tank 16. For example, the evaluation value is multiplied by a predetermined coefficient to calculate the unit price of the waste oil, and this is then multiplied by the amount of stored waste oil to calculate the purchase price of the waste oil. Note that the amount of stored waste oil used in this calculation may be calculated based on flow rate data, or may be detected by an oil amount sensor (not shown) provided in the waste oil tank 16.

[0031] The schedule creation unit 50 creates a cooking oil collection schedule based on the latest collection date and time stored in the collection date and time database 31 and the past flow rate data stored in the flow rate database 32. For example, based on the past flow rate data, it determines the consumption trend of cooking oil in each fryer 17, and predicts the collection time when collection will be necessary based on the determined consumption trend and the latest collection date and time. Then, based on the predicted collection time, it determines the collection date and time for the waste oil tank 16 and creates a collection schedule including the collection date and time. The created collection schedule is sent to the mobile terminal 12, and the collection worker collects cooking oil from the waste oil tank 16 in accordance with the collection schedule.

[0032] (Explanation of waste oil evaluation operation) Next, with reference to Fig. 5, a description will be given of the waste oil evaluation operation by the collection management server 13. This waste oil evaluation operation is an operation for evaluating the quality of the waste oil currently stored in the waste oil tank 16. The waste oil evaluation operation is an example of a waste oil evaluation method.

[0033] 5, in the waste oil evaluation operation, first, the collection management server 13 acquires flow rate data relating to the waste oil tank 16 from each flow meter 14 using the flow rate data acquisition unit 41 (S1) (flow rate acquisition step). For example, it transmits an information request signal to each flow meter 14, and in response receives and acquires the flow rate data transmitted from each flow meter 14. After acquiring the flow rate data, it records the acquired flow rate data in the flow rate database 32 in association with the identification information of the waste oil tank 16, the fryer 17, and the store (S2).

[0034] Once the flow rate data has been recorded in the flow rate database 32, the deterioration level data acquisition unit 42 acquires deterioration level data relating to the waste oil tank 16 from each deterioration level sensor 15 (S3). For example, an information request signal is sent to each deterioration level sensor 15, and in response, the deterioration level data transmitted from each deterioration level sensor 15 is received and acquired. Once the deterioration level data has been acquired, the acquired deterioration level data is recorded in the deterioration level database 33 in association with the identification information of the waste oil tank 16, the fryer 17, and the store (S4).

[0035] After the deterioration level data is recorded in the deterioration level database 33, the waste treatment identification unit 43 identifies the waste treatment from each fryer 17 to the waste oil tank 16 based on the flow rate data of each flow meter 14 stored in the flow rate database 32 (S5). For example, each section in the flow rate data where the flow rate continues to be equal to or greater than a certain amount is identified as one waste treatment. After the waste treatment is identified, the start date and end date and time of each waste treatment, as well as identification information of the waste oil tank 16, fryer 17, and store that perform each waste treatment, are associated with each identified waste treatment and recorded in the waste treatment database 34 (S6).

[0036] Thereafter, the treatment flow rate determination unit 44 determines the flow rate of the edible oil in each waste treatment based on the flow rate data of each flow meter 14 stored in the flow rate database 32 and the start date and time and end date and time of each waste treatment recorded in the waste treatment database 34 (S7). For example, the flow rate of the edible oil in that waste treatment is calculated by extracting and integrating the flow rates detected between the start date and time and end date and time of the waste treatment from the flow rate data of each flow meter 14. Once the flow rate of each waste treatment has been determined, the determined flow rate for each waste treatment is recorded in the waste treatment database 34 (S8).

[0037] After the flow rate of each waste treatment is recorded in the waste treatment database 34, the treatment deterioration level determination unit 45 determines the deterioration level of the edible oil to be disposed of in each waste treatment based on the deterioration level data stored in the deterioration level database 33 and the start date and time of each waste treatment recorded in the waste treatment database 34 (S9) (edible oil determination step). For example, the deterioration level of the edible oil at the start date and time of each waste treatment is extracted from the deterioration level data of each deterioration level sensor 15, and the extracted deterioration level is determined as the deterioration level of the edible oil in each waste treatment. After the deterioration level of each waste treatment is determined, the determined deterioration level of each waste treatment is recorded in the waste treatment database 34 (S10).

[0038] After the deterioration level of each waste treatment is recorded in the waste treatment database 34, the treatment liquidity level determination unit 46 determines the SFI value of the edible oil to be disposed of in each waste treatment (S11) (edible oil determination process). For example, based on the order information and delivery information of the edible oil, the brand of edible oil to be disposed of in each waste treatment is identified, and the SFI value of the edible oil is obtained from that brand based on the ingredient information provided by the manufacturer. After the SFI value of each waste treatment is determined, the determined SFI value of each waste treatment is recorded in the waste treatment database 34 (S12).

[0039] After determining and recording the deterioration level and SFI value for each waste treatment, the treatment evaluation value calculation unit 47 calculates the quality evaluation value of the edible oil to be disposed of by each waste treatment based on the deterioration level and SFI value for each waste treatment stored in the waste treatment database 34 (S13). For example, the quality evaluation value of the edible oil is calculated by dividing the SFI value by the deterioration level. After calculating the quality evaluation value for each waste treatment, the calculated quality evaluation value for each waste treatment is recorded in the waste treatment database 34 (S14).

[0040] Once the quality evaluation value of each waste treatment is recorded in the waste treatment database 34, the waste oil evaluation unit 48 evaluates the quality of the waste oil currently stored in the waste oil tank 16 based on the flow rate and quality evaluation value of each waste treatment stored in the waste treatment database 34 (S15) (waste oil evaluation step). For example, one or more waste treatments carried out for the waste oil tank 16 from the most recent collection date and time to the present are extracted, and the flow rate and quality evaluation value for each of the extracted one or more waste treatments are multiplied, and the sum of the multiplied values ​​is divided by the total flow rate of the one or more waste treatments to calculate the quality evaluation value for the waste oil.

[0041] After calculating the evaluation value of the waste oil, the purchase price calculation unit 49 calculates the purchase price of the waste oil stored in the waste oil tank 16 based on the calculated evaluation value of the waste oil and the amount of waste oil stored in the waste oil tank 16 (S16). For example, the evaluation value is multiplied by a predetermined coefficient to calculate the unit price of the waste oil, and this is then multiplied by the amount of stored waste oil to calculate the purchase price of the waste oil. This completes the waste oil evaluation operation.

[0042] (Actions and Effects of the Embodiments) As described above, according to the configuration of the above embodiment, the waste oil stored in the waste oil tank 16 after one or more waste treatment processes is evaluated based on the flow rate for each waste treatment process detected by the flow meter 14 and the deterioration level and SFI value of the edible oil discarded in each waste treatment process. This allows the quality and mixing ratio of the edible oil mixed into the waste oil to be determined and the waste oil to be evaluated. This makes it possible to accurately and easily evaluate the waste oil stored in the waste oil tank 16. This promotes the reuse of edible oil and contributes to environmental conservation.

[0043] In addition, since the waste oil recovery system 1 is equipped with multiple flow meters 14 and deterioration sensors 15 according to the number of fryers 17, the waste oil stored in the waste oil tank 16 can be evaluated more accurately.

[0044] Furthermore, the schedule creation unit 50 is configured to predict when the waste oil tank 16 needs to be collected by utilizing the flow rate data of the flow meter 14 used to evaluate the waste oil. Therefore, there is no need to provide a special flow meter 14 to predict when the waste oil tank 16 needs to be collected, and the waste oil collection system 1 can be configured simply.

[0045] In addition, by adopting a cooking oil disposal method in which cooking oil is disposed of from the fryers 17 of multiple stores in the building into a single waste oil tank 16 installed in the building, there is no need to collect cooking oil from the waste oil tank 16 for each store, which makes it possible to further reduce the frequency of cooking oil collection.

[0046] (Other embodiments) Although the embodiments of the present invention have been described above, the invention according to the claims is not limited to the above-described embodiments. It should be noted that not all of the combinations of features described in the embodiments are necessarily essential to the means for solving the problems of the invention. The present invention can be implemented by modifying it as appropriate within the scope of its spirit.

[0047] For example, in the above embodiment, both the degree of deterioration and the degree of liquidity are determined, and the waste oil is evaluated based on both the degree of deterioration and the degree of liquidity. However, it is also possible to determine only one of the degree of deterioration and the degree of liquidity, and evaluate the waste oil based on either the degree of deterioration or the degree of liquidity.

[0048] In the above embodiment, the processing liquidity determination unit 46 is configured to identify the brand of edible oil and obtain the liquidity of the edible oil from the brand, but it may be configured to identify the type of edible oil and obtain the liquidity of the edible oil from the type. Also, a liquidity sensor may be provided in the fryer 17 to directly detect and obtain the liquidity.

[0049] Furthermore, in the above embodiment, the waste oil stored in the waste oil tank 16 by the most recent disposal treatment after collection is evaluated, but if the waste oil in the waste oil tank 16 cannot be completely collected during the cooking oil collection operation for the waste oil tank 16, waste oil may remain in the waste oil tank 16 after collection. In this case, it is preferable to evaluate the waste oil by taking into account the amount and quality of the waste oil remaining after collection in addition to the flow rate and quality evaluation value of each disposal treatment.

[0050] In the above embodiment, the collection management server 13 is configured to have the flow rate data acquisition unit 41, the deterioration level data acquisition unit 42, the waste treatment specification unit 43, the treatment flow rate determination unit 44, the treatment deterioration level determination unit 45, the treatment liquidity determination unit 46, the treatment evaluation value calculation unit 47, the waste oil evaluation unit 48, and the purchase price calculation unit 49. However, the customer's information processing device may have some or all of these. In other words, the customer may use the waste oil evaluation system and the waste oil evaluation method of the present invention to understand the quality and purchase price of the waste oil.

[0051] Furthermore, in the above embodiment, the quality evaluation value is used to calculate the purchase price, but the quality evaluation value may be notified. That is, the waste oil recovery system 1 (waste oil evaluation system) may be further provided with an evaluation result notifying unit that notifies the evaluation result (evaluation value) of the waste oil by the waste oil evaluation unit 48. For example, the evaluation result notifying unit may be configured to notify the customer of the evaluation result of the waste oil by the waste oil evaluation unit 48.

[0052] Furthermore, in the above embodiment, cooking oil is disposed of from a plurality of stores into a single waste oil tank 16, but cooking oil may be disposed of from only a single store into the waste oil tank 16. Furthermore, in the above embodiment, cooking oil is disposed of from a plurality of fryers 17 into a single waste oil tank 16, but cooking oil may be disposed of from only a single fryer 17 into the waste oil tank 16. In other words, the waste oil evaluation system and waste oil evaluation method of the present invention can be applied to waste oil tanks 16 for these types of cooking oil disposal.

[0053] Furthermore, in the above embodiment, cooking oil is disposed of in the waste oil tank 16 from the fryer 17, but cooking oil may be disposed of in the waste oil tank 16 from other cooking appliances.

[0054] Furthermore, in the above embodiment, cooking oil is disposed of in the waste oil tank 16 from cooking equipment in the store, but cooking oil may also be disposed of in the waste oil tank 16 from cooking equipment in a factory such as a central kitchen or a fried food manufacturing factory.

[0055] (Summary of the embodiment) Next, the technical concepts grasped from the above-described embodiments will be described using the reference numerals and the like in the embodiments.
