Embodiments for Carrying Out the Invention

[0010] Hereinafter, the joint drying and preparation facility 1 according to the embodiment of the present invention will be described with reference to the drawings. In addition, the thickness, dimensions, etc. of each member are appropriately omitted for the purpose of explanation.

[0011] As shown in FIG. 1, the joint drying and preparation facility 1 includes a water supply device 10, a building unit 20 including at least a silo 21 capable of heating the water supplied from the water supply device 10, a heat pump 60 connected to the building unit 20 for discharging warm air and sending the cooled water to a plurality of heat exchangers 30, 40 and a dust collector 50, and a dryer 70 for drying grains to which warm air is sent from the heat pump 60. In this specification, the "building" includes a building.

[0012] The water supply device 10 includes a pump for sending out the water supplied to the water supply device 10, a motor as a driving device for driving the pump, and an inverter as a frequency converter for driving the motor at a variable speed (none of which are shown). The water supply device 10 is connected to a pipe 10a through which water passes when the water supply device 10 sends water to the building unit 20 through an opening (water supply port) formed in the water supply device 10, a pipe 10b through which water passes when the water is sent from the heat exchangers 30, 40, and a pipe 10c through which water passes when the water is sent from the dust collector 50 to the water supply device 10 through an opening (water receiving port) formed in the water supply device 10. In addition, the water supply device 10 includes a backflow prevention valve for water disposed in the water receiving pipe, a filter (strainer) fitted to the water receiving port, and a backflow prevention valve for water provided at the water supply port which is the discharge port of the pump (none of which are shown). The filter is used to physically separate the solids contained in the water used in the dust collector 50 from the water. When the preset required amount of water is supplied to the water supply device 10, the water supply to the water supply device 10 from outside the device is stopped.

[0013] The building unit 20 may include at least one building selected from the group consisting of a parking lot 22 and a country elevator 23 in addition to the silo 21.

[0014] The parking lot 22 and the country elevator 23 are facilities provided near the silo 21 and the dust collector 50. The parking lot 22 is a facility formed by asphalt-paving the surface of a certain area of land. The country elevator 23 is a building provided at least near the silo 21 and is a facility used for storing grains and the like.

[0015] Pipes (heat pipes 24) for conveying water are arranged under the wall surfaces of the silo 21 and the country elevator 23 and under the asphalt of the parking lot 22. By circulating the heat pipes 24, water is heated using solar thermal energy.

[0016] When the silo 21, the parking lot 22, and the country elevator 23 are each erected, as shown in FIGS. 2(A) and (B), they are arranged in a linear or delta shape in plan view. At this time, in order to expose the above facilities to the sunlight necessary for achieving the effects of the present invention, the user of the co-drying preparation facility 1 appropriately selects an arrangement that can maximize the surface area of the side surface and / or upper surface of the above facilities irradiated with sunlight from sunrise to sunset.

[0017] The heat pipes 24 arranged on the wall surfaces of the silo 21 and the country elevator 23 are preferably arranged along the orbit of the sun in order to efficiently utilize solar thermal energy. In addition, the heat pipes 24 arranged under the asphalt of the parking lot 22 are arranged at a sufficient depth in order to heat the water flowing inside the heat pipes 24 using solar thermal energy.

[0018] The dust collector 50 is of a wet type. The heat pump 60 sends cold water to the dust collector 50 and injects it inside the dust collector 50, thereby reducing the temperature inside the dust collector 50. Also, this can suppress the growth of fungi and reduce malodor. Further, by bringing the exhaust of the dryer into contact with the shower of the dust collector 50, part of the heat of the exhaust of the dryer can be recovered.

[0019] The cold water used in the dust collector 50 is then sent to the water supply device 10 through the pipe 10c.

[0020] The heat pump 60 exchanges heat with the water sent from the building unit 20 and generates cold water and warm air. The heat pump 60 extracts heat from the warm water to produce warm air. This warm air is used as a heat source for drying the grains. Also, the warm water heated by the heat pump 60 turns into cold water.

[0021] Also, the heat pump 60 sends cold water to the heat exchangers 30 and 40 respectively.

[0022] The heat exchangers 30 and 40 exchange heat between the cold water and the air. The heat exchanger 40 exchanges heat with the cold water sent from the heat pump 60 to generate cold air and even colder water, and sends the cold air into the silo 21 to cool the grains inside the silo 21. The cold water generated here is sent to the water supply device 10.

[0023] The heat exchanger 30 exchanges heat with the cold water sent from the heat pump 60 through a route different from the route connecting the heat exchanger 40 to the heat pump 60 to generate cold air and even colder water, and sends the cold air into the dryer 70 to cool the inside of the dryer 70. The heat exchanger 30 may not be used when there is no grain in the silo. Also, the cold air generated by the heat exchange is used for the dryer 70 that has entered the cooling process to accelerate the rate of decrease in the grain temperature after drying. The cold water generated here is sent to the water supply device 10.

[0024] The cold water sent from the heat exchangers 30 and 40 and the dust collector 50 is sent to the building unit 20, heated using solar energy while passing through the heat pipe 24, and circulates.

[0025] The dryer 70 is a rectangular parallelepiped container for storing and drying grains. A duct 61 used for blowing the warm air from the heat pump 60 is connected to the dryer 70. Also, ventilation holes are formed for exhausting the air used for drying the grains and for circulating the air inside the dryer 70.

[0026] In addition, the dryer 70 is provided with an opening / closing mechanism for accommodating and taking out grains. The dryer 70 is formed of a heat-resistant material. Thereby, even if the temperature of the warm air is relatively high, the effect of drying the grains can be achieved.

[0027] Note that the present invention is not limited to the above-described form, and various modifications and applications are possible.

[0028] In the present embodiment, the parking lot 22 has been described as a facility provided in the vicinity of the silo 21, the dust collector 50, and the country elevator 23, but it is not limited thereto. For example, if the parking lot 22 can heat water using at least solar heat energy, as shown in FIG. 3, it may be provided so as to encompass these facilities.

[0029] In the present embodiment, the pipe 10b has been described as a pipe through which water passes when being sent from the water supply device 10 to the heat exchangers 30 and 40, but it is not limited thereto. For example, as shown in FIG. 4, it may be a pipe through which water passes when being sent from the heat exchangers 30 and 40 to the building unit 20.

[0030] In addition, the pipe 10c has been described as a pipe through which water passes when being sent from the dust collector 50 to the water supply device 10, but it is not limited thereto. For example, it may be a pipe through which water passes when being sent from the dust collector 50 to the building unit 20.
