Configure to supply. 13n is a wind fan motor.

  As shown in FIGS. 3 and 5, a controller (control unit) 40 is mounted on the upper surface of the wind tunnel with a detachable bolt or the like. A controller 40 operation panel 41 is provided in front of the burner wind tunnel 14. The operation panel 41 includes a tension switch 42, a ventilation switch 43, a drying switch 44, a discharge switch 45, and a stop switch 46. The switch group is used to switch to various operation modes and to stop the operation. In addition, if the emergency stop switch 47 is provided and the emergency stop switch 47 is operated, the entire aircraft operating unit can be stopped almost simultaneously.

  In addition to these switches 42 to 47, a tension amount setting switch 48 for setting the tension amount, a moisture setting switch 49 for setting the final finishing moisture value, and a drying setting switch 50 (drying speed in the case of drought drying) Is set to fast, normal, and slow, and in the case of other grain drying, for example, a drying speed set in advance in association with varieties such as wheat and barley is set. Furthermore, timer increase / decrease switches 51 and 52 are provided for drying the finished product according to the processing time without depending on the moisture value.

  The moisture detecting means employs a single-grain moisture sensor 53, measures the moisture value in units of a predetermined number of grains every predetermined time, averages the detection results for a predetermined number of times, calculates the moisture value, and operates the operation panel 41. The display unit 54 alternately displays the detected hot air temperature and the like. In addition, the control unit 40 is configured to be able to determine the variation in moisture from the moisture value of one grain or to determine the number of immature grains, and these are displayed by three LEDs 55 and 56.

  In addition to inputting operation mode information and the like from the switch of the operation panel 41 to the control unit 40, detection information is input from various sensors to control the fuel supply amount of the vaporizing burner 13 and to transfer the grain. Is configured to control the operation.

  Next, the effect | action of the grain dryer K of the said structure is demonstrated. The grain thrown into the tension hopper (not shown) is tensioned into the storage tank 2 via the elevator 17, the upper transport device 32, and the like that are driven by turning on the tension switch 42. When the squeezing of the grain is completed, the process proceeds to a drying operation. In the previous stage, the setting of the grain type and the desired dry finish moisture value are set by the moisture setting switch 49 and the drying setting switch 50.

  When the drying switch 44 is turned on after the setting operation is completed, the elevator 17, the upper / lower transport devices 25 and 31, the feeding valve 7 and the like are started to be driven, and the burner 13 is also driven so that the hot air flows into the drying chamber 3. It is supplied toward the entrance of the hot air chamber 6 which is a rhombus space.

  Here, the flame of the burner is hot-aired by the rotation of the suction fan 15 and flows into the hot-air chamber 6 while being mixed with the external air appropriately introduced, and the hot air acts on the grains flowing down through the flow-down passages 5 and 5. A drying action is performed.

  The drying action by the hot air is performed before and after the grain flow passages 5 and 5, and the hot air that has passed through the grain flow passages 5 and 5 is exhausted through the exhaust chambers 16 and 16. The grain dried in the drying chamber 3 is returned again to the storage tank 2 via the lower conveying device 25, the elevator 17 and the upper transfer spiral 31 of the cereal collecting chamber 4, and undergoes a tempering action. Such a process is repeated and drying is completed when a predetermined moisture value is reached.

  As shown in the control block diagram of FIG. 6, on the input side of the control unit 40, a switch input such as the tension switch 42, a moisture sensor 53 input, a digital sensor input such as a grain flow sensor outside the figure, Besides having an analog sensor input typified by a temperature sensor such as an outside air temperature, a card reading / writing device 57 is connected to the control unit 40 via an input circuit and an output circuit. On the other hand, the output side has a suction fan and a grain circulation system motor output, a feed valve motor output, a burner combustion system output, and a display unit. 58 is a memory, and 59 is a communication device.

  A plurality of grain dryers K configured as described above are installed and operated in a predetermined farmer A, and the small farms B and C in the vicinity contract with the farmer A without having a private dryer. In this system, the dryer K can be used. Further explanation based on FIG. 7, Farmer A has a plurality of units (5 units of dryers K1 to K5 in the illustrated example), and while drying their own harvested grains, Has signed a usage contract and is using these B or C dryers. Each farmer performs user registration in consideration of his / her own experience and surrounding conditions, and contracts and uses the dryers K1 to K5 as a farmer.

  The card reading / writing device 57 is configured so that the magnetic card 60 owned by each user is detachably inserted and the data written in the card 60 is read by the control unit 40. That is, the magnetic card 60 is an example of a recording unit, and has a configuration in which user data and drying condition data are written. When there are a plurality of users B and C who have signed a use contract with the owner A's grain dryer in advance, write data that can identify A, B or C as user data, The type of drying control (drying speed control, constant temperature drying control, etc.) and the required control reference value (0.8% / hour, 20 ° C. difference from outside air temperature, etc.) are written. The card reading / writing device 57 of the control unit 40 calls the write data through the insertion port 57a of the card 60, and the control unit 40 recognizes the drying conditions. In the card 60, user information and operation information as basic information, that is, a code number assigned to the user, various drying operation modes (for example, a drying speed control operation mode, a constant temperature drying control mode, etc.) are selected in advance. It stores the dry operation mode. In addition to this, as special information, it is configured to execute, for example, hot air temperature correction control based on outside air humidity, automatic extension amount automatic setting control, and the like based on an external command signal, and further writes and inputs information described later. . Further, after the operation, the operation start time, operation end time, fuel consumption amount, etc. in each work mode can be written. FIG. 8 shows an example of the writing data. In the example shown in the figure, the drying information can be written together.

  At the end of the drying operation of the registered user, the owner of the dryer K calculates a charge based on a predetermined calculation standard, that is, a usage fee, and bills the registered user. At that time, in the display data of FIG. 8 (b) above, taking into account the conversion to the electricity bill by the operating time as the billing information, the price conversion from the fuel consumption amount as the other billing information, and the predetermined basic charge. Thus, the total amount is calculated, and these calculation formulas and the like are stored in the controller in advance and are calculated every time when the discharging operation is completed (FIG. 8C).

  A card reading / writing device 57 is provided in the vicinity of the operation panel 41 so that card information and reservation information can be displayed on the display unit. Therefore, by operating the reservation call switch 61 of the operation panel 41, reservation contents such as a user name and a reservation date and time are displayed on the display unit 54. When the reservation call switch 61 is configured on the operation panel 41, the reservation status can be confirmed and grasped, which is convenient for the user's work planning.

  The card 60 insertion operation is configured to be performed on the grain dryer K before a predetermined tension. That is, when the card 60 is inserted (step 101), it is determined whether or not there is a card input (step 102). When card information is read (step 103), user information is first confirmed and drying conditions are set (steps 104 and 105).

  When the above conditions are set, it is determined whether or not the operation is started (step 106). On the other hand, the control unit 40 starts the management of the usage time (step 107), and at the same time, the operation of tensioning, drying and discharging is performed. Management is executed (steps 108 to 110), and when this is completed, usage time management is ended (step 111). This end information is written to the card 60 together with the driving time (step 112), and user information and driving information are also written to the memory of the control unit 40 (step 113). When this series of processing is completed, the card 60 is automatically ejected (step 114). If the operation is not started in step 106, the process skips to step 114 and the card 60 is ejected (FIG. 9).

  In the system configuration of FIG. 7, each of the dryers K1 to K5 is provided with a dedicated controller 40, and these are connected to constitute a control device 62. The control device 62 is configured to connect various control units of the controllers 40, 40... And the card reading / writing devices 57, 57. It is connected to the Internet via the Internet, and necessary information can be exchanged by external communication means such as the portable terminal 64. By comprising in this way, it communicates between a user's portable terminal machine 64 and the controller 40 of the grain dryer K, and user information and driving | operation by the grain dryer K controller 40 side by the information from the portable terminal machine 64 It is configured to recognize the conditions and perform the operation, and to transmit the information of the controller 40 to the portable terminal 64. The central manager M is, for example, the owner of the dryers K1 to K5. The central manager M may be a system in which a sales company of the grain dryer K in the area is in charge of grasping the operation state and checking whether it is in a normal operation state. When configured as described above, the kernel dryer K including the controller 40 and the card reading / writing device 57 is connected to the network so that the operation can be managed, and a user other than the owner of the kernel dryer can be operated. When it is desired to use the dryer K, the empty state of the grain dryers K1 to K5 can be confirmed by the portable terminal 64, and the operation efficiency can be improved. In addition, it is good also as a structure which starts a drying operation based on applicable card | curd information by outputting a starting command signal to the controller 40 of the dryer K. FIG. In particular, when driving at night, it is convenient because the operation of the drying switch of the dryer K is not required.

  In the system configuration of FIG. 7, the contracted dryer is configured by a plurality of dryers K1 to K5. However, an administrator who collectively manages the dryers K11 to K14 owned by each farmer is placed to It may be used for contract farmers as well as for individual use (Fig. 10).

  Moreover, the example in the said FIG. 7 tries to prevent a quality fall as a structure which can store the receiving grain of the user who wants to use temporarily. Depending on the operating conditions of the grain dryer K of the individual farmer that the user who is a contract farmer wants to use, it may not be possible to dry immediately. In such a case, a ventilation tank T is prepared separately from the grain dryer K. In the same manner as the grain dryer K, the card 60 can be operated. That is, the controller 40 and the card reading / writing device 57 are configured in the ventilation tank T adjacent to the grain dryer K, and the ventilation operation process is performed on the condition of the card 60 input as in the dryer K operation. It is.

  Meanwhile, driving information can be included in the output information of information from the portable terminal 64. If it does in this way, transmission / reception of data will be attained without using media, such as a card | curd, by performing the said user's identification and driving | running condition determination using a portable terminal device of users other than an owner. That is, in contrast to the configuration in which the card reading / writing device 57 is provided and the dryer K is used by a plurality of arbitrary users other than the owner, in the case of FIG. 11, there is no contact between the portable terminal 64a and the controller 40. Data is transmitted / received (transmission / reception system), and the controller 40 side user information and driving conditions are recognized on the basis of information from the portable terminal 64 to perform driving. As a specific example of the transmission / reception system, data from the portable terminal 64a is transmitted by infrared irradiation or magnetic action by bringing the portable terminal 64a close to the detection unit of the controller 40.

  Accordingly, the drying condition data can be transmitted from the user's portable terminal 64 even during the drying, and the setting contents of the controller 40 can be changed. As shown in FIG. When the received data from 64a is read, it is determined whether or not the user involved in the transmission of the data is a registered person, and it is determined whether or not the user is a registered user and is in use, that is, a user currently in the drying process. If these are true, a message indicating that the received data is accepted is displayed (steps 201 to 205). The controller 40 reads the data necessary for the drying operation from the received data and performs the drying operation (step 206). If there is a change input, the setting is changed and the drying is performed (steps 207 and 208).

  When the user information transmitted by the external communication means does not correspond to the user information data set in advance on the dryer controller 40 side, the unique information (for example, portable terminal number) of the read external communication means is used as user information. A new user registration is executed to shift to the operation process. That is, the received data from the mobile terminal is read and the user information is confirmed (steps 301 to 302). If it is determined that the data is not registered on the controller side (step 303), there is a registration input together with a display indicating no registration. The user information is registered after obtaining the confirmation (steps 304 to 306). Thereafter, the operation is started after step 307 and appropriately processed (FIG. 13).

  FIG. 14 shows that the ventilation tank T is configured separately from the grain dryer K when the card dryer / controller 57 is provided in the grain dryer controller 40 to perform operation management based on the information of the card 60 read. When the grain dryer K is in use, a system that can be ventilated is used, and when the dryer K is free and can perform a drying operation, a means for contacting a user who is ventilated is configured. The user who is using the ventilation tank is configured so as to give priority to the subsequent drying operation.

  When driving information is included in the output information of the information from the portable terminal 64, the user can identify the user and determine the driving conditions by using the portable terminal 64 of the user other than the owner. Data can be transmitted and received without using a medium, but the example shown in FIG. 15 is configured to contact the user when the discharge operation is not performed even after a certain period of time has elapsed after the grain drying. That is, the drying is finished (step 401), the combustion system output and the motor system output for controlling the grain circulation are turned off (steps 402 and 403), and the completion information is transmitted to the portable terminal of the user related to the drying (step 404). ). Count the elapsed time from the end of drying, for example, combustion system output off (step 405), and determine whether or not the discharge start is performed by the presence or absence of discharged kernels (step 406) If the discharge operation is not performed even after a certain time has elapsed, the end information is transmitted to the user again (steps 407 and 408). With this configuration, the end information is communicated not only at the end of drying, but also when the discharge is not performed, thereby prompting the user to discharge quickly and efficiently operating the dryer. Can do.

  In addition, the driving information can be written in the portable terminal 64 and used to settle the usage fee. In FIG. 9, after a series of processes in steps 101 to 110 are executed, transmission data is read, user information is confirmed, and then, usage information is transmitted (steps 111 to 113). With this configuration, the controller 40 transmits / receives data to / from the user's portable terminal, and transmits the usage status, for example, operation time, fuel consumption, etc. from the controller 40 to the portable terminal 64 after the drying is completed. Thus, the user can confirm the charge on the portable terminal 64, and performs settlement later. An example of calculating the charge is the basic charge plus the electricity charge required for the operation time and the fuel amount for hot air drying as described above.

  Further, in the system including the ventilation tank T, information about the end of drying and the end of discharge in the grain dryer K is transmitted to a user who is using the ventilation tank T. That is, the ventilation tank which can ventilate separately from the grain dryer K is provided, and it comprises so that driving | operation with a card | curd is possible like a dryer. At this time, the controller 62 that manages the operation of the whole system determines the progress of drying of the grains already stuck in the grain dryer K, and if the ventilation tank T is in use, The user determines that the operation state of the grain dryer K is the end of drying or the end of discharge, and notifies the user that the dryer K can be used immediately or soon (FIG. 16). ). The transmission of the drying end information is also transmitted to the user related to the drying. At that time, the transmission time is accompanied. However, when the end time is late at night, it is assumed that the contact is made after waiting until early morning. By managing the time, it is possible to set an appropriate contact time, and the user is not worried.

  In addition, a drying operation reservation means is configured so that the user who is using the ventilation tank T is preferentially used for the subsequent use of the grain dryer K. The operation reservation starts the drying operation at the set time, and the reservation time can be set in the controller 40 of the dryer K. For example, when a user inserts a card, information related to the user and driving information are displayed on the display unit 54, and the display unit 54 is switched to a reservation time setting display by operating the reservation switch 61. The reservation can be completed by inputting the operation time, and drying starts at the time. Therefore, a user shall complete grain insertion by the said reservation time, and the controller 40 is the structure which can monitor for the timely utilization condition of the dryer K at any time, and can accept reservation so that drying work may not overlap.

  That is, when the insertion port 57a of the card 60 is configured in the controller 40 of the ventilation tank T and the card 60 is inserted (steps 501 and 502), the information written in the card is read and the user information is confirmed (step 501). 503, 504), ventilation is started by appropriately performing a switch operation for starting operation (step 505), and usage time management is started simultaneously (step 506). During this ventilation operation or before the start of ventilation operation, user reservation registration is performed so that it can be preferentially used when the grain dryer is free (step 507), and this reservation information is transmitted to the control device (step 508). Thereafter, the ventilation operation process is performed, and when the operation is completed, the operation completion process is performed, the use time management is completed, and the operation time is written in the card (steps 509 to 513). Therefore, by preferentially reserving the user who is using the ventilation tank T, it is possible to prevent a drop in grain quality of the user waiting for drying and to operate the drying system efficiently (FIG. 17).

  Due to the difference between the grain dryer K that can be reserved for operation and the grain dryer K that cannot be reserved, the dryer K that cannot be reserved is provided with a ventilation tank T. With such a configuration, a dryer that can be reserved is used for a user who uses it continuously or regularly, and a ventilation tank T is connected to the standard dryer K for a user in case of irregular use or emergency. Operate to use a system with Therefore, efficient system operation is possible according to the user's situation. In addition, if the dryer K and the ventilation tank T are provided side by side so that card operation can be performed as a set, deterioration of the grain quality of the user waiting for drying can be prevented, and the drying system can be operated efficiently.

  FIG. 18 shows a measure in the case of the dryer provided with the above-described drying operation reservation means when preparations such as grain insertion are not made even at the reservation time, and when the operation reservation is made, the operation reservation It authenticates that it is the user who concerns. For example, when a predetermined time before the reservation time is reached, authentication can be performed by comparing the user and the reservation time with previously inserted card information. By using the communication line means between the Internet and the portable terminal 64, the user's end information of the previous user is communicated to the user, thereby prompting the user to insert grains (steps 601 to 604). If the reservation user is not ready to dry the grain due to information such as the fact that the tension operation has not started even when the reservation time is reached, the end information of the previous user is notified once again just in case (step 606). If there is an answer and the reservation is cancelled, or if there is no answer and the fixed time elapses, the reservation is canceled as well. By configuring in this way, it is possible to quickly confirm the presence or absence of use of the reserved user, and it is possible to secure a dryer that can be used by performing reservation cancellation and efficiently operate the drying system. .

  In addition, with respect to the user related to the above-mentioned operation reservation, as the configuration in which the end information is communicated to the user's mobile terminal device etc. via the Internet or the like when the previous drying discharge operation ends, the work management of the reserved user And an efficient drying system operation is possible (FIG. 19).

  In the grain dryer T provided with the card reading / writing device 57, a situation where the operation is unexpectedly hindered is caused while the drying operation is continued based on the card information. For example, when the card is removed from the card insertion slot, that is, when the third party user is not aware, the card 60 is removed due to misunderstanding by the user in use, or the stop switch 46 is unexpectedly pressed. In the drying operation while reading from the card 60, the original data is lost, and there is a possibility that the drying cannot be continued. When the stop switch 46 is operated, the same confusion is caused. For this reason, the following improvements have been made. First, regarding various operation switch inputs, when user information is confirmed by the card reading / writing device 57 and there is user information, the operation switch input is accepted. Even if there is an operation switch input such as a tension switch, when user information is not input, this is not accepted (FIG. 20).

  Next, a description will be given of the control measures for the operation when the card is extracted during the drying operation. In FIG. 21, when the card 60 is inserted, the controller 40 reads the written information and the user information is confirmed (steps 701 to 704). When the tension switch 42 is operated, it is determined that the tension operation is performed, and each part drive motor is activated and output, and the tension operation processing is performed (steps 705 and 706). Similarly, when the drying switch 43 is operated, it is determined that the drying operation is performed, and the grain circulation system and the burner 13 necessary for the drying operation are activated to perform the drying operation process (steps 707 and 708). If a return request for the card 60 is made by operating the return switch 65 during the drying operation, the card 60 is removed from the insertion slot 57a (steps 709 and 710). Regardless of which operation switch is pushed by this extraction, reading of the operation switch is prohibited so that the drying operation is not hindered (step 711). When the drying process is completed and it is determined that the discharge operation is performed by the operation of the discharge switch, the discharge conveyance system is driven to discharge the dried grains to the outside (steps 712 to 715). When the discharge operation is completed, the operation information such as the operation time, the amount of fuel used, etc. is written on the card, but the presence or absence of a card is determined at the card insertion slot. In this case, the above information is written (steps 716 to 718), and then the card is ejected from the insertion slot (step 719).

  As described above, when the user using the dryer removes the card from the dryer, even if there is an input from the operation switch, it is prohibited to read the operation switch so that the operation switch does not operate. It is possible to prevent a situation in which the setting contents are changed during drying or the machine is stopped due to an operation other than the user who is operating or an erroneous operation.

  As described above, even if the configuration is such that the card 60 is removed and the input of the operation switch is prohibited, the operation input is accepted in the following cases, thereby enabling a rational operation of the machine. That is, (1) when the user's card 60 is removed from the card insertion slot 57a and the operation input is prohibited, the emergency stop switch 47 is excluded from the input prohibition. The machine can be safely stopped when an abnormality occurs (FIG. 22). (2) When the user's card is removed from the card insertion slot 57a and the operation input is prohibited, the reservation calling operation by the reservation switch 61 is excluded from the input prohibition, and the input is performed when operated regardless of the presence of the card 60. The other user can confirm the reservation information (FIG. 23). (3) When the user's card 60 is removed from the card insertion slot 57a and operation input is prohibited, a master card 66 capable of performing all operations of the dryer K is created. It is possible to accept, and even when the user is absent, it is possible to perform an operation such as a setting change even when an urgent setting change is unavoidable, and the work can be performed with peace of mind (FIG. 24).

  The example shown in FIG. 25 intends to use the grain dryer K as a storage tank. The grain dryer K is provided with a temperature control device 70 so that the temperature of the storage tank 2 part can be controlled. For example, a ventilation duct 71 that can introduce hot air from the burner is configured in the storage tank 2, and the controller 40 is configured to configure a storage operation mode and operate the mode as necessary. When the storage operation is selected (step 801), the temperature adjusting device is turned on to read the temperature in the storage tank, and when it is low, the operation output of the temperature adjusting device 70 by the burner is changed (steps 802 to 805). The temperature control device 70 is turned off in response to information on the end of operation, for example, stop output information by operating the portable terminal 64 or a stop switch provided (steps 806 and 807).

  FIG. 26 relates to an improvement in the configuration of the controller 40. That is, the controller 40 is provided separately for the operation unit 40a and the operation / display unit 40b, and data is exchanged between them by CAN communication, and an emergency stop switch 47 is provided on the operation unit 40a side. It becomes. Since it is a conventional integrated controller, there is no degree of freedom in mounting and operation position, and there was room for improvement because the controller could not be shared for display types such as LED or LCD. If configured, the user can perform operation and display confirmation at a preferred position, and the operation unit 40a does not choose an installation location, so the installation configuration of the dryer K itself is simplified. Further, by performing data transmission / reception by CAN communication as an individual controller, it is possible to reduce the routing of signal lines, improve noise resistance, and reduce the number of wires. In FIG. 27, the main controller 40A for controlling the drying, the burner controller 40B for controlling the fuel supply amount and the wind fan rotation, and the moisture for calculating the average value by converting the crushing resistance value of the grain into the moisture value. It is configured by the measurement controller 40C, and effects such as a reduction in the number of wires can be obtained in the same manner as described above.

  In addition, when comprised with these controllers, it can be set as the structure which detects the temperature sensor value used by control of each controller with the main controller 40A, and transmits to other controllers 40B and 40C as temperature data. Therefore, after the temperature sensor data used redundantly by each controller is detected by the main controller 40A and the temperature is calculated, it is transmitted to another controller. With this configuration, the temperature sensor data used by a plurality of controllers is detected by the main controller 40A, and the data transmission to the other controllers 40B and 40C can be performed, so that the routing of the signal lines can be reduced. Improve noise and reduce the number of wires. Specific examples of the temperature sensor include a grain temperature sensor necessary for the main controller 40A and the moisture measurement controller 40C, and a hot air temperature sensor and an outside air temperature sensor necessary for the main controller 40A and the burner controller 40B.

  FIG. 28 shows a configuration in which power necessary for the dryer 76 can be supplied by a fuel cell 77 attached to the machine. That is, the fuel cell 77 is supplied with hydrogen accompanying the reforming process of the city gas and oxygen accompanying the introduction of air, and combines the fuel cell stack 78 to generate power. The frequency of the electric current generated by this power generation is adjusted by the inverter 79 and then supplied to the grain dryer 76 to be used for starting up each part. On the other hand, the exhaust heat generated in the fuel cell stack 78 can be supplied to the grain dryer 76 by the blower 86 so as to be used as a heat source necessary for drying. Further, the supply line 82 from the inverter 79 to the grain dryer 76 is branched, and the supply line 84 is connected to a switchboard 83 on the way from commercial power to each household indoor wiring. When in use, it can be used as a household power source. In addition, a power storage unit 85 is configured on the output side of the fuel cell to supply the control device and the like. That is, the power required for the operation of a dryer such as a grain dryer is supplied by a fuel cell 77 attached to the machine, and a power storage unit 85 for storing a certain amount of electricity is provided after the fuel cell stack 78 to generate power. By adopting a configuration capable of supplying electric power when the dryer 76 is started or when the dryer 76 is started, the fuel cell 77 can be continuously operated even when power generation is stopped. Further, when the operation of the dryer 76 and the operation of the fuel cell 77 are performed in conjunction with each other, it can be used as an auxiliary power source until the output of the fuel cell 77 reaches a rating. This configuration can be applied to various machines that require a power source in addition to a dryer. Although city gas is used as a raw fuel for generating hydrogen, kerosene may be used.

  Waste heat from the blower 86 is provided so as to be branched and supplied to the hot air chamber 6 and the burner 13 of the dryer K. That is, the waste heat induced from the blower 86 through the duct 87 to the front side of the dryer K is bifurcated. One 87a is placed in the elevator 17 and the other 87b is placed in the burner wind tunnel 14. . Of these, the duct 87 b is further branched, the large-diameter duct 87 c is viewed at the entrance of the hot air chamber 6, and the small-diameter duct 87 d is connected to the support cylinder 13 c of the burner 13. Moreover, each branch part is equipped with the adjustment valves 88a and 88b, and is a structure which can adjust steplessly from a closed attitude | position to a maximum opening. Therefore, during the tension operation, by supplying mainly into the elevator 17, high-temperature wind acts even in the case of tension of high moisture grains, contributing to drying and steaming in the storage tank 2. To prevent. Moreover, since a part of the waste heat is also supplied to the hot air chamber 6, it is possible to prevent stuffiness by driving the feed valve and applying the high temperature air while performing so-called circulation tension. At the start of the drying operation, when the outside air temperature is low, the air is supplied to the support cylinder 13c of the burner 13 so that high-temperature air acts from the blower cylinder to the vaporization cylinder to improve fuel diffusion.
