Description

Transport methods, transport support methods, transport support devices and programs

The present invention relates to a transportation method, a transportation support method, a transportation support device, and a program.

Currently, packages such as fruits and vegetables are being transported from the shipping base to the destination by a refrigerated transport vehicle. In refrigerated transportation using a refrigerated transport vehicle, the refrigerating temperature of the luggage varies depending on the position where it is loaded in the vehicle, and the refrigerating effect is reduced due to loading / consolidating and unloading. In addition, when a refrigerated transport vehicle is used, the luggage may be transshipped on the way, or the luggage may be left at room temperature upon arrival. Therefore, even if the luggage is kept cold, it is difficult to maintain the low temperature state to the destination.

Therefore, in recent years, a refrigerant storage space for storing refrigerants such as dry ice, ice, ice packs, and cold storage materials has been provided in a heat insulating container for storing luggage, and the refrigerant stored in the refrigerant storage space is cooled to the luggage. (For example, see Patent Documents 1 to 4). By adopting such technology, it is said that the low temperature of the luggage can be maintained by the cold air supplied from the refrigerant.

Japanese Unexamined Patent Publication No. 2004-43020 Japanese Unexamined Patent Publication No. 2008-256336 Japanese Unexamined Patent Publication No. 2015-9838 Japanese Patent No. 6436822

However, when the conventional technology as described in Patent Documents 1 to 4 is adopted, it is necessary to prepare a refrigerant such as dry ice in advance or to replenish or replace it in the middle, and preparation and replenishment of such a refrigerant. -The replacement work was complicated. Further, since the refrigerant storage space is provided in the heat insulating container, the space for storing the luggage is narrowed, so that the load capacity of the luggage is reduced and the transportation efficiency is lowered.

The present invention has been made in view of such circumstances, and provides a transportation method capable of maintaining a low temperature state of an object without using a refrigerant such as dry ice and realizing high transportation efficiency. The purpose is to provide. Another object of the present invention is to provide a method, an apparatus and a program capable of accurately setting precooling conditions for a perishable product when transporting the perishable product at room temperature to support the perishable transport at room temperature.

In order to achieve the above object, the transportation method according to the present invention includes a precooling step of precooling an object, a surrounding step of surrounding the precooled object with a heat insulating material panel, and an object surrounded by a heat insulating material panel. It includes a transport process for transport. In the precooling step, the object can be precooled in the range of −60 to 20 ° C.

By adopting such a method, the pre-cooled object can be surrounded by the heat insulating material panel and transported, so that the object can function as a refrigerant in the space inside the heat insulating material panel. Therefore, the object can be transported even during transportation. The low temperature state can be maintained. Therefore, for example, even when the outside air temperature is higher than the temperature of the object, it is possible to prevent the object from being heated by the outside air temperature, and it is possible to prevent the quality of the object from deteriorating. Further, even when the outside air temperature is lower than the temperature of the object, it is possible to prevent the object from being supercooled by the outside air temperature, and it is possible to prevent chilling injury of the object (for example, fruits and vegetables). In this method, since it is not necessary to use a refrigerant such as dry ice, it is possible to omit the work of separately preparing the refrigerant and replenishing / replacing the refrigerant in the middle, and the refrigerant storage space can be omitted. It is possible to increase the load capacity of the vehicle and realize high transportation efficiency.

In the transportation method according to the present invention, in the precooling step, when the temperature of the object (landing temperature) at the time of arrival at the destination is set, the outside air temperature and the object are achieved so that the landing temperature is achieved. The precooling temperature can be set by calculating the heat transfer based on the amount (bulk density and volume) of the object, the specific heat of the object, the transportation time, and the heat resistance value of the heat insulating material panel.

If such a method is adopted, the precooling temperature can be appropriately set based on the outside air temperature and the like so that the temperature of the object (landing temperature) at the time of arrival at the destination is achieved.

In the transport method according to the present invention, in the precooling step, the objects can be divided into at least two target groups, and the target groups can be precooled under different precooling conditions. At this time, in the siege step, the objects precooled in the precooling step can be surrounded by different heat insulating material panels.

If such a method is adopted, the object group can be transported in the pre-cooling temperature zone suitable for maintaining the freshness.

In the transport method according to the present invention, in the precooling step, the objects can be divided into at least two target groups, and the target groups can be precooled under different precooling conditions. At this time, in the surrounding step, the object group precooled in the precooling step can be surrounded by the same heat insulating material panel.

In the transportation method according to the present invention, in the encircling step, the ratio of the volume of the object to the total volume of the space inside the heat insulating panel is set to 30% or more, or the density of the object inside the heat insulating panel is set. It can be set to 30 kg / m ^{3 or more.}

When such a method is adopted, the ratio of the volume of the object (bulk occupancy) to the total volume of the space inside the heat insulating panel is set to a specific value (30%) or more, or the object inside the heat insulating panel is used. Since the density of is set to a specific value (30 kg / m ³ ) or more, the desired refrigerant effect can be maintained. If the bulk occupancy is less than 30% or the density is ^{less than 30 kg / m 3} , the desired refrigerant effect cannot be maintained, which is not preferable.

In the transportation method according to the present invention, in the encircling step, a heat insulating material panel made of a heat insulating material having a thermal resistance of ^{50 m 2 · K / W or less can be used.}

When such a method is adopted, the object is surrounded by a heat insulating material panel made of a heat insulating material having a specific thermal resistance (50 m ² · K / W or less), so that the heat insulating effect can be effectively maintained.

In the transportation method according to the present invention, in the encircling step, a heat insulating material panel made of a heat insulating material having ^{a thermal resistance of 0.3 m 2 · K / W or more per 10 mm in thickness can be used.}

If this method is adopted, thermal resistance can be secured even if the thickness of the heat insulating material panel is reduced, and the transportation capacity can be increased.

In the transportation method according to the present invention, in the encircling step, a heat insulating material panel made of a heat insulating material having a bending strength of ^{0.15 N / mm 2 or more can be used.}

When such a method is adopted, since the object is surrounded by the heat insulating material panel made of the heat insulating material having a specific bending strength (0.15 N / mm ² or more), the deformation of the heat insulating material panel during transportation is suppressed and the vibration occurs. -It is possible to absorb impact and suppress crushing, reliably protect the object, and effectively maintain the heat insulating effect.

In the transportation method according to the present invention, in the siege step, the object can be surrounded by an airtight housing having a gas exchange rate of 1 time / hour or less, which is composed of a heat insulating material panel.

When such a method is adopted, since the object is surrounded by a housing having a specific airtightness (gas exchange rate of 1 time / hour or less) composed of a heat insulating material panel, the gas concentration (for example, CO ₂ concentration) in the housing is increased. Can be controlled. Therefore, for example, when the object is fruits and vegetables, the respiration of fruits and vegetables can be suppressed to maintain the freshness.

Further, the transportation support method according to the present invention is a method executed by a computer to support normal temperature transportation of perishables, and is request information including information on the type and amount of perishables and information on the transportation destination. It includes an acquisition process for acquiring the above, a calculation process for calculating the pre-cooling condition when pre-cooling the perishable product based on the request information, and an output process for outputting the pre-cooling condition.

Further, the program according to the present invention is a program for causing a computer to execute the transportation support method described above.

It is provided with a calculation unit for calculating the pre-cooling condition when pre-cooling the perishable product based on the request information, and an output unit for outputting the pre-cooling condition. In addition, "normal temperature transportation" in this specification includes transportation without cooling or heating. For example, the transportation may be carried out by using a transportation means or the like which does not have a cooling device, or may be carried out by using a transportation means or the like which does not have a heating device.

When such a configuration and method are adopted, request information including information on the type and quantity of perishables and information on the transportation destination is acquired, and precooling conditions for precooling perishables based on the acquired request information. Can be calculated and the calculated precooling condition can be output. Therefore, it is possible to output an accurate pre-cooling condition by inputting the request information provided by the client and provide the output pre-cooling condition to the perishables keeper. Then, the custodian who receives the provision of such pre-cooling conditions can appropriately pre-cool the perishables before shipment under the accurate pre-cooling conditions, so that it is possible to maintain the quality of the perishables at the transportation destination.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following embodiments are merely suitable application examples, and the scope of application of the present invention is not limited thereto.

<Transportation method>
First, the transportation method according to the embodiment of the present invention will be described. The transportation method according to the present embodiment is a method of transporting a predetermined object in a pre-cooled state, and includes a pre-cooling step of pre-cooling the object, a surrounding step of surrounding the pre-cooled object with a heat insulating material panel, and the like. It includes a transportation process for transporting an object surrounded by a heat insulating panel. The objects are, for example, fruits and vegetables, meat, fresh fish, beverages, processed foods, grains, cosmetics, pharmaceuticals, flowers, tea leaves, coffee beans, etc., and these are stored in a housing (cardboard box, iron container, etc.). Also includes.

In the pre-cooling process, the object is pre-cooled within the range of -60 to 20 ° C. For example, when the object is fruits and vegetables, it is pre-cooled in the range of 0 to 15 ° C in the pre-cooling process, and when the object is meat or fresh fish, it is pre-cooled in the range of -60 to 10 ° C in the pre-cooling process. When the object is a beverage (such as canned coffee or paper pack beverage), it is pre-cooled in the range of -5 to 5 ° C in the pre-cooling process, and when the object is a processed food (such as chilled food). Pre-cool in the pre-cooling process within the range of -5 to 5 ° C, and if the object is grains (such as rice and wheat), pre-cool in the pre-cooling process within the range of 5 to 15 ° C, and the object is cosmetics. In some cases, the pre-cooling process precools in the range of -20 to 20 ° C, and if the object is a pharmaceutical product, the pre-cooling process precools in the range of -60 to 10 ° C, and the object is a flower. In the pre-cooling process, pre-cool in the range of 0 to 15 ° C, if the object is tea leaves, pre-cool in the pre-cooling process in the range of -20 to 15 ° C, and if the object is coffee beans. Precool in the range of -20 to 15 ° C in the precooling step.

In the precooling process, when the temperature of the object (landing temperature) at the time of arrival at the destination is set, the outside air temperature and the amount (bulk density and volume) of the object are achieved so that the landing temperature is achieved. The precooling temperature can be set by calculating the heat transfer based on the specific heat of the object, the transportation time, and the heat resistance value of the heat insulating material panel. In this way, the precooling temperature can be appropriately set based on the outside air temperature and the like so that the temperature of the object (landing temperature) at the time of arrival at the destination is achieved. Further, in the precooling step, the objects can be divided into at least two target groups, and the target groups can be precooled under different precooling conditions.

In the siege process, the objects precooled in the precooling process can be surrounded by different heat insulating material panels. For example, put cabbage and carrots pre-cooled to 5 ° C in the first heat-insulated container, put peppers and tomatoes pre-cooled to 10 ° C in the second heat-insulated container, and put onions pre-cooled to 1 ° C in the third heat-insulated container. , These first, second and third heat insulating containers can be transported by one transport vehicle. In this way, the object group can be transported in the pre-cooling temperature zone suitable for maintaining the freshness (in contrast, the conventional refrigerating vehicle can transport the object group in only one pre-cooling temperature zone).

Further, in the siege step, the object group precooled in the precooling step can be surrounded by the same heat insulating material panel. In this way, one object group acts as a cooling agent for the other object group, and it can be transported while maintaining the freshness as a whole. This is especially effective when a group of objects with different heat capacities are mixedly loaded. For example, a group of objects that are precooled to 3 ° C and are difficult to change in temperature (for example, potatoes) and a group of objects that are precooled to 1 ° C and are easily changed in temperature (for example, leafy vegetables such as spinach) are mixedly loaded in one heat insulating container. Can be transported.

In the siege step, the ratio of the volume of the object to the total volume of the space inside the heat insulating panel (bulk occupancy) is set to 30% or more, or the density of the object inside the heat insulating panel is set to 30 kg / m. ^{Set to 3} or more. Since the bulk occupancy of the object is set to a specific value or more or the density of the object is set to a specific value or more in this way, the desired refrigerant effect can be maintained. If the bulk occupancy is less than 30% or the density is ^{less than 30 kg / m 3} , the desired refrigerant effect cannot be maintained, which is not preferable.

In the siege process, a heat insulating panel made of a heat insulating material having a thermal resistance of ^{50 m 2 · K / W or less is used.} Since the object is surrounded by the heat insulating material panel made of the heat insulating material having a specific thermal resistance in this way, the heat insulating effect can be effectively maintained. Further, in the encircling step, a heat insulating material panel made of a heat insulating material having ^{a thermal resistance of 0.3 m 2 · K / W or more per 10 mm in thickness can be used.} In this way, the thermal resistance can be secured even if the thickness of the heat insulating material panel is reduced, and the space for storing the luggage can be increased.

Further, in the encircling step, a heat insulating material panel made of a heat insulating material having a bending strength of ^{0.15 N / mm 2 or more is used.} Since the object is surrounded by the heat insulating material panel having a specific bending strength in this way, it is possible to suppress the deformation of the heat insulating material panel during transportation and to absorb vibrations and shocks to suppress crushing. It is possible to reliably protect the object and effectively maintain the heat insulating effect. Further, in the siege step, the object is surrounded by an airtight housing having a gas exchange rate of 1 time / hour or less, which is composed of a heat insulating material panel. Since the object is surrounded by the housing having a specific airtightness in this way, the gas concentration (for example, CO ₂ concentration) in the housing can be controlled. Therefore, for example, when the object is fruits and vegetables, the respiration of fruits and vegetables can be suppressed to maintain the freshness.

After that, the heat insulating container 1 containing the object is transported to a predetermined destination using a refrigerated transport vehicle or the like (transportation process).

When the object is transported to a predetermined destination using the heat insulating container 1, the top plate 50 of the heat insulating container 1 is first removed, and then the front plate 10 and the side plates 30 are removed from the

grooves

61 and 63 of the pedestal 60, respectively. As shown in FIG. 4, a laminated body P composed of a front plate 10, a side plate 30, and a top plate 50 is formed. Next, the laminated body P is loaded on the first support portion 81 of the support member 80 by using the second support portion 82 as a guide. At this time, since the height of the second support portion 82 of the support member 80 is substantially the same as the height of the laminated body P when all the parts are aligned, the shortage of the plates constituting the laminated body P is visually observed. Can be easily recognized with.

In the transportation method according to the above-described embodiment, the precooled object is surrounded by a heat insulating material panel (front plate 10, rear plate 20, side plate 30, bottom plate 40, and top plate 50) to be insulated. Since the object can function as a refrigerant in the space inside the material panel (internal space of the heat insulating container 1), the low temperature state of the object can be maintained even during transportation. Therefore, for example, even when the outside air temperature is higher than the temperature of the object, it is possible to prevent the object from being heated by the outside air temperature, and it is possible to prevent the quality of the object from deteriorating. Further, even when the outside air temperature is lower than the temperature of the object, it is possible to prevent the object from being supercooled by the outside air temperature, and it is possible to prevent chilling injury of the object (for example, fruits and vegetables). In this method, since it is not necessary to use a refrigerant such as dry ice, it is possible to omit the work of separately preparing the refrigerant and replenishing / replacing the refrigerant in the middle, and the refrigerant storage space can be omitted. It is possible to increase the load capacity of the vehicle and realize high transportation efficiency.

Further, in the transportation method according to the embodiment described above, a heat insulating material panel (front plate 10, rear plate 20, side plate 30, bottom plate) made of a heat insulating material having ^{a specific bending strength (0.15 N / mm 2 or more).} Since the object is surrounded by 40 and the top plate 50), deformation of the heat insulating material panel during transportation can be suppressed, vibration and impact can be absorbed to suppress crushing, and the object can be reliably protected and insulated. The effect can be maintained effectively.

Further, in the transportation method according to the embodiment described above, in order to surround the object with a housing (insulation container 1) having a specific airtightness (gas exchange rate of 1 time / hour or less) composed of a heat insulating material panel. , The gas concentration in the housing (for example, CO ₂ concentration) can be controlled. Therefore, for example, when the object is fruits and vegetables, the respiration of fruits and vegetables can be suppressed to maintain the freshness.

Can also be composed of insulation panels). Further, in the above embodiment, an example in which the support member 80 having an L-shaped cross section is adopted has been shown, but such a support member is not essential, and the object may be surrounded only by the heat insulating material panel. At this time, it is preferable to surround the object with a housing having a specific airtightness composed of a heat insulating panel having a specific thermal resistance and bending rigidity.

<Transport support device>
Next, the functional configuration of the transport support device 100 according to the embodiment of the present invention will be described with reference to FIG.

The transportation support device 100 according to the present embodiment is for supporting the normal temperature transportation of precooled fresh products, and is an information acquisition unit for acquiring various information such as request information sent from the requester C or the like. 101, an information calculation unit 102 for calculating various information such as pre-cooling conditions, and an information output unit 103 for outputting various information such as pre-cooling conditions calculated by the information calculation unit 102 to the custodian P and the like. It is provided with various databases 104 (request information database 104A, fresh product information database 104B, transportation information database 104C, packing information database 104D) for recording various information. The “fresh product” in the present embodiment means foods and the like that deteriorate due to temperature changes during transportation, and for example, fruits and vegetables (vegetables and fruits), meat, fresh fish, grains, tea leaves, coffee beans, flowers and the like. including. Further, the "fresh product" in the present embodiment shall also include frozen foods.

The information acquisition unit 101 functions to acquire the request information sent from the requester C and to receive various information input from the user of the transportation support device 100, and the information acquisition unit 101 functions to receive the communication unit 140 (in FIG. 6). It is composed of an input unit 150 (described later in FIG. 6) and an input unit 150 (described later). As shown in FIG. 5, the request information is _{input from the terminal UC owned by the requester C} to the information acquisition unit 101 of the transportation support device 100 via the communication network N. The terminal U _C, it is possible to use various electronic apparatuses having an information display unit and an information input unit and the communication unit (desktop PC, a notebook PC, a smart phone, etc.). The communication network N is an information communication network capable of connecting a plurality of computers to each other, and may be a global information communication network such as the Internet. The request information acquired through the information acquisition unit 101 is stored in the request information database 104A.

Request information includes information on the type and quantity of perishables. For example, "cucumber (600 kg)", "green pepper (300 kg)", "eggplant (200 kg)", "lettuce (200 kg)", "potato (150 kg)" and the like are included in the request information. In this embodiment, perishable information (for example,) related to perishables such as “corn” and “okla” that have a large amount of breathing and perishables such as “soybeans” that are easily rubbed by vibration during transportation (for example). "Respiratory heat" and "friction heat") are recorded in the perishables information database 104B, and when these perishables are included in the request information, the perishables information related to the perishables can be obtained from the perishables information database 104B. It is read and used to calculate the precooling conditions described later. In addition, the request information includes information on the transportation destination (location information of the transportation destination, etc.).

The information calculation unit 102 precools the fresh product based on the request information acquired by the information acquisition unit 101 and the information (fresh product information, transportation information, packing information) read from various databases 104 based on the request information. It functions to calculate the pre-cooling conditions. Specifically, the information calculation unit 102 calculates the transportation time required to transport the perishable product to the transportation destination and the temperature fluctuation of the perishable product during transportation, and precools based on the transportation time and the temperature fluctuation. Calculate the conditions.

The transportation time required to transport the perishables to the transportation destination includes preset initial information (location information of the perishables storage location, transportation vehicle) in addition to the information on the transportation destination included in the request information. It can be calculated based on information on various types of transportation (transportation route, transportation distance, etc.) set from information on the transportation destination, etc. These initial information and information related to transportation are recorded in the transportation information database 104C as transportation information, and when information about the transportation destination is input as request information, the transportation information about the transportation destination is read from the transportation information database 104C. It is designed to be used. For example, the location information of the storage location of fresh products is "Nobeoka City, Miyazaki Prefecture", the location information of the transportation destination is "Ota Ward, Tokyo (Ota Market)", and the transportation route is "land route and route". In this case, the estimated transportation distance can be calculated as "1050km", and the average cruising speed is assumed to be "70km / h" based on the specifications of the transportation vehicle, so the transportation time is calculated as "15 hours". To.

The temperature fluctuations of perishables during transportation include the heat entering during transportation inside the heat-insulating container 1 (see FIGS. 1 to 4) for transporting perishables and the fresh food stored in the heat-insulating container 1. It can be calculated based on the weight and specific heat of the product. Here, the heat entering into the heat insulating container 1 during transportation can be calculated based on the air temperature inside and outside the heat insulating container 1, the heat transfer area of the heat insulating container 1, and the heat transfer rate. The heat transfer coefficient of the heat insulating container 1 can be calculated based on the heat transfer coefficient inside and outside the heat insulating container 1 and the thickness and thermal conductivity of the heat insulating material constituting the heat insulating container 1. The heat of entry may take a negative value. That is, when heat is emitted from the heat insulating container 1 during transportation, the ingress heat becomes a negative value.

The heat transfer rate C _HTR of the heat insulating container 1 is determined by the design specifications of the heat insulating container 1. That is, the heat transfer coefficient inside the heat insulating container 1 is C _HTI , the heat transfer coefficient outside the heat _{insulating container 1 is C HTO} , and the heat insulating material panels constituting the heat insulating container 1 (front plate 10, rear plate 20, side plate already described). 30, bottom plate 40 and the thickness _{T H} of the top plate 50), when the thermal conductivity of the insulating panel _{C TC,} that the heat transfer coefficient _{C HTR} of the heat insulating container 1 is calculated by the following equation (1) ..
_{_{_{C HTR = 1 / {1 /}}} C HTO + (T H / C TC)} + 1 / C HTI ... (1)
_{The user of the transportation support device 100 calculates the heat transfer rate C HTR} of the heat insulating container 1 at the stage when the design specifications of the heat insulating container 1 are finalized, inputs the value through the information acquisition unit 101, and inputs the value to the transportation support device D. It can be recorded as packing information in the installed packing information database 104D.

Further, the temperature of I _T in the interior of the heat insulating container _1, the temperature O _T at the outside of the heat insulating container _1, when the heat transfer area of the heat insulating container 1 A _T, to, come during transport inside the insulated container 1 It enters heat H _P is calculated by the following equation (2).
_{_{_{H P = (O T -I T}}} ) × A T × C HTR ... (2)
The heat transfer area _{AT of the} heat insulating container 1 can also be recorded in advance in the packing information database 104D as packing information. The temperature I _T in the interior of the heat insulating container 1, it is possible to employ a product temperature (1 hour ago at the time of for example calculation) of fresh products housed in the heat insulating container 1. The temperature O _T at the outside of the heat insulating container 1, can be employed air temperature is input as the request information transport destination.

Then, assuming that the weight of the perishable product stored in the heat insulating container 1 is W and the specific heat of the perishable product is S, the temperature fluctuation ΔT of the perishable product during transportation is calculated by the following mathematical formula (3).
_{ΔT = (H P / W)} × S ... (3)
The specific heat S of the fresh product is recorded in the fresh product information database 104B as the fresh product information, and when the type of the fresh product is input as the request information, the specific heat S of the fresh product is read from the fresh product information database 104B. It is used to calculate temperature fluctuations. When the fresh product is a vegetable, its specific heat S can be assumed to be the same value as the specific heat of water.

The temperature fluctuation may take into account the respiration heat generated by the perishable product per unit time. Such respiratory heat may use a constant value, or may be expressed as a function of the _{temperature inside the box, the CO 2 concentration, or the like.} As a specific value of respiratory heat, for example, the value described in Journal of Agricultural Machinery Society 55 (2): 69-75, 1993 69 can be used. Further, the temperature fluctuation may take into account the frictional heat during transportation. Such frictional heat can be calculated from the friction coefficient for each product type, the surface pressure according to the packing state of fresh products, the movement speed, the amount of frictional heat per unit movement, and the like.

In this way, the precooling condition can be calculated using the information on the respiration heat and frictional heat of the perishable product set based on the request information (information on the perishable product). Therefore, when the "breathing heat" cannot be ignored because the fresh product has a large amount of breathing such as "corn" and "okra", or when the fresh product is rubbed by vibration during transportation like "soybean". Pre-cooling conditions can be accurately calculated even when "friction heat" cannot be ignored because it is easy to use.

The information calculation unit 102 uses the above mathematical formulas (1) to (3) based on the request information acquired by the information acquisition unit 101 and the information read from various databases 104 based on the request information during transportation. The temperature fluctuation ΔT of fresh products can be calculated. When the temperature fluctuation ΔT is positive, it is also called “temperature rise”, and when ΔT is negative, it is also called “temperature fall”. Then, the information calculation unit 102 calculates the precooling condition based on the temperature fluctuation ΔT calculated in this way and the separately calculated transportation time. At this time, the information calculation unit 102 can calculate the pre-cooling condition so that the temperature of the perishable product (temperature at the time of landing) at the time of arrival at the transportation destination satisfies a predetermined condition. As an example, the precooling condition can be calculated so that the landing temperature is less than a predetermined threshold value. For example, when the fresh product is a potato and the temperature fluctuation ΔT when the calculated transportation time elapses is “5 ° C”, the landing temperature of the potato is set to be less than a predetermined threshold value (10 ° C). , Set (calculate) the initial product temperature T ₀ of the potato to "5 ° C". The initial product temperature T ₀ referred to here is an example of precooling conditions. The threshold value used here can be recorded in the perishables information database 104B for each type of perishables.

In addition, the information calculation unit 102 can calculate the pre-cooling condition so that the integrated temperature of the perishable product until it arrives at the transportation destination satisfies a predetermined condition. As an example, the precooling condition can be calculated so that the integrated temperature becomes less than a predetermined threshold value. In this case, information calculating unit 102, temperature fluctuation [Delta] T 1 of fresh products every preset time, for example, from transport start time every _hour, [Delta] T _2, ..., and calculates the [Delta] T _N, the temperature fluctuation [Delta] T ₁ , ΔT ₂ , ..., Hourly fresh product temperature T ₁ , T ₂ , ..., _TN is calculated, and these hourly fresh product temperatures T ₁ , T ₂ , ..., T _{The integrated temperature ΣT is calculated by integrating N up} to the time when transportation is completed. _{The perishable product temperature T 1} one hour after the start of transportation is obtained by adding _{the temperature fluctuation ΔT 1} for 0 to 1 hour to the initial product temperature T _0. _{Further, the product temperature T 2} of the perishable product 2 hours after the start of transportation is obtained by adding _{the temperature fluctuation ΔT 2} of 1 to 2 hours to the product temperature T _{1 1 hour later.} Similarly, product temperature _{T N} of perishables after N time from the transport start, (N-1) to the product temperature _{T N-1} after time (N-1) adding the temperature variation [Delta] T _N of ~ N times Obtained by doing. The information calculation unit 102 calculates the _{integrated temperature ΣT by integrating the perishable product temperatures T 1} , T ₂ , ..., _TN every hour until the transportation is completed, and the calculated integrated temperature ΣT is predetermined. _{The initial product temperature T 0} of the perishable product can be set (calculated) so as to be less than the threshold value of. The threshold value used here can also be recorded in the perishables information database 104B for each type of perishables.

The information calculation unit 102 may repeat the simulation by changing _{the initial product temperature T 0} once set in order to optimize the landing temperature (or integrated temperature) of the perishable product. For example, if the initial product temperature T ₀ of a certain fresh product is set to "0 ° C", the landing temperature is calculated as "5 ° C", and if the initial product temperature T ₀ is set to "5 ° C", the landing temperature is "10". In the case where it is calculated as "° C" and the initial product temperature T ₀ is set to "10 ° C" and the landing temperature is calculated as "15 ° C", if the quality of the fresh product is "10 ° C" or less, it will not deteriorate. In such a case, it is possible to avoid deterioration of the fresh product when it arrives at the transportation destination without setting _{the initial product temperature T 0} _{to "0 ° C", so that the initial product temperature T 0} is set. It is possible to avoid extra precooling by setting it to "5 ° C". The information calculation unit 102 can also change the content (kg) of the perishable product and the design specifications of the heat insulating container 1 as necessary during the simulation. Further, the information calculation unit 102 may estimate (calculate) the pre-cooling condition by statistical processing, machine learning, or the like by using the correlation history between the request information when the perishables were transported in the past and the pre-cooling condition. Good.

The “pre-cooling condition” in the present embodiment _{is not limited to the initial product temperature T 0} , but includes the storage condition of the perishable product before the start of transportation (including not only “pre-cooling” but also “preheating”). Can be done. The pre-cooling conditions are, for example, _{the set temperature of the pre-cooler for pre-cooling the fresh product to a predetermined initial product temperature T 0} , the pre-cooling temperature of the heat insulating container 1 for storing the fresh product, and the fresh product for each predetermined weight (predetermined volume). It is also possible to adopt the pre-cooling temperature of the packing box for packing in small portions as the pre-cooling condition. The storage conditions include the set temperature of the precooler for preheating the perishable product to a predetermined initial product temperature T ₀ , the preheating temperature of the heat insulating container 1 for storing the perishable product, and the perishable product for each predetermined weight (predetermined volume). It is also possible to adopt the preheating temperature of the packing box for packing in small portions.

The initial product temperature T ₀ (pre-cooling condition) can be calculated for each type of perishable product. In this case, the initial product of the case (the worst case in which the temperature fluctuates most easily) in which only one type of fresh food is stored in the heat insulating container 1 in a predetermined volume and the remaining space in the heat insulating container 1 is assumed to be air. The temperature T ₀ is calculated. If such a method is adopted, the temperature fluctuation of each perishable product can be suppressed compared to the worst case when other kinds of perishable products are stored in the remaining space (all perishable products have a larger specific heat than air and have a higher temperature than air). This is because it is hard to fluctuate). _{In addition, the initial product temperature T 0} is calculated for each type of perishable product using the above method, the average value of the initial product temperature T ₀ for all types is calculated, and the average value is used as the precooling temperature (precooling) of the heat insulating container 1. It can be adopted as a condition). At this time, instead of adopting the average value, the initial product temperature T ₀ of the heaviest fresh product may be used as a representative value, and the representative value may be adopted as the pre-cooling temperature (pre-cooling condition) of the heat insulating container 1.

It is composed of 160 (described later in FIG. 6).

As the terminal _UP, as with the terminal U _C , various electronic devices having an information display unit, an information input unit, and a communication means can be adopted.

In this example, the case where the transportation support device 100 is composed of one computer will be described, but the transportation support device 100 may be composed of a plurality of computers. For example, the display unit 160 may be composed of a plurality of displays. Further, the configuration shown in FIG. 6 is only an example, and it is not necessary to have a part of these configurations. Further, a part of the configuration may be provided in a remote place.

<Transport support method>
Subsequently, a transportation support method using the transportation support device 100 according to the present embodiment will be described with reference to the flowchart of FIG. 7.

First, the information acquisition section 101 of the transport support apparatus 100 acquires the request information sent from the terminal U _C held by the requester C through the communication network N (request information acquisition step: S1). The request information acquired in the request information acquisition step S1 includes information on the type and quantity of perishables and information on the transportation destination.

Next, the information calculation unit 102 of the transportation support device 100 calculates the pre-cooling condition for pre-cooling the perishable product based on the request information acquired in the request information acquisition step S1 (pre-cooling condition calculation step: S2). In the pre-cooling condition calculation step S2, the transportation time required to transport the perishable product to the transportation destination and the temperature fluctuation of the perishable product during transportation are calculated based on the request information and the like, and the transportation time and the temperature fluctuation are calculated. The precooling condition is calculated based on this. The specific calculation method of the precooling condition is as described above. That is, the information calculation unit 102 first calculates the heat transfer coefficient based on the heat transfer coefficient inside and outside the heat insulating container 1 and the thickness and thermal conductivity of the heat insulating material panel constituting the heat insulating container 1. Next, the ingress heat is calculated based on the air temperature inside and outside the heat insulating container 1, the heat transfer area and the heat transfer rate of the heat insulating container 1. Next, the temperature fluctuation is calculated based on the calculated ingress heat and the weight and specific heat of the perishable product stored in the heat insulating container 1. After that, based on the calculated temperature fluctuation and the separately calculated transportation time, the temperature of the perishables at the time of arrival at the transportation destination (or the integrated temperature of the perishables until the arrival at the transportation destination) is a predetermined threshold value. The precooling condition (for example, initial product temperature T ₀ ) is calculated so as to be less than.

Then, the information output unit 103 of the transport support apparatus 100, the pre-cooling condition calculated by the pre-cooling condition calculation step S2, and outputs to the terminal U _P held by the custodian P via the communication network N (pre-cooling condition output step: S3 ). The custodian P who has been provided with the pre-cooling conditions can pre-cool the perishable products before shipment according to the pre-cooling conditions, and can ship the perishable products when the pre-cooling is completed.

It should be noted that the required total volume (number of heat insulating containers 1) can be calculated based on the type and weight of the perishable product to be transported by using the information calculation unit 102 of the transportation support device 100 according to the present embodiment. For example, if the fresh produce to be transported is "cucumber (600 kg)", "green pepper (300 kg)", "eggplant (200 kg)", "lettuce (200 kg)", "potato (150 kg)", it is as follows. Calculate the total volume.

First, when subdividing "cucumber (600 kg)" into 15 L (10 kg) packaging boxes, 60 packaging boxes are required, and the total volume of these 60 packaging boxes is 900 L. Next, when subdividing "green peppers (300 kg)" into 10 L (4 kg) packaging boxes, 75 packaging boxes are required, and the total volume of these 75 packaging boxes is 750 L. Next, when subdividing "eggplant (200 kg)" into 15 L (8 kg) packaging boxes, 25 packaging boxes are required, and the total volume of these 25 packaging boxes is 375 L. Next, when subdividing "lettuce (200 kg)" into 30 L (10 kg) packaging boxes, 20 packaging boxes are required, and the total volume of these 20 packaging boxes is 600 L. Finally, when subdividing "potato (150 kg)" into 15 L (15 kg) packaging boxes, 10 packaging boxes are required, and the total volume of these 10 packaging boxes is 150 L. Therefore, the total required volume is (900 + 750 + 375 + 600 + 150 =) 2775L. Assuming that the volume of one heat insulating container 1 is 1500 L, two heat insulating containers 1 are required to store all the fresh produce having a total volume of 2775 L.

When the type and weight of the fresh products to be transported are input, the information calculation unit 102 of the transportation support device 100 refers to the weight and volume of each packing box for each fresh product stored in the table in advance. Then, the total volume of each fresh product and the total volume thereof (total volume) are calculated, and the information regarding the total volume (the number of required heat insulating containers 1) is provided to the custodian P via the information output unit 103. Can be done. Upon receiving such information, the custodian P can appropriately distribute the perishables into the two heat insulating containers 1.

For example, the keeper P sorts the heavy fresh foods (“cucumber (600 kg)” and “green pepper (300 kg)”) into the two heat insulating containers 1, and then the volume and weight in each heat insulating container 1 are increased. The remaining perishables can be sorted so that they are almost even. For example, the first heat insulating container 1 is divided into "cucumber (600 kg: 900 L)" and "eggplant (200 kg: 375 L)", while the second heat insulating container 1 is "pepper (300 kg: 750 L)". "," Lettuce (200 kg: 600 L) "and" potato (150 kg: 150 L) "can be sorted (first sorting method).

Alternatively, the keeper P can divide the weight of each perishable product by the required number of heat insulating containers 1 (2 pieces) to determine the packing amount in each heat insulating container 1. That is, in each of the two heat insulating containers 1, "cucumber" is 300 kg (450 L), "green pepper" is 150 kg (375 L), "eggplant" is 100 kg (187.5 L), and "lettuce" is 100 kg (300 L). 75 kg (75 L) of "potato" can be sorted (second sorting method).
