摘要： PROBLEM TO BE SOLVED: To provide a circulating type grain dryer capable of preventing burning-scorching of a grain and overheat of a grain gathering chamber by instantly performing coping treatment without causing a time lag when the drying grain stays in the grain gathering chamber of a high temperature. SOLUTION: This circulating type grain dryer 1 has a refining chamber 2, the grain gathering chamber 3, a far infrared radiation radiating part 5, and grain circulating means 7, 8, and 9. A grain stay detecting device is arranged in the grain gathering chamber 3. This grain stay detecting device has a state change detecting means 11 and a cooling means 14 for detecting a state change in the grain gathering chamber 3 by a change in a flowing state, for example, a change in a presence range and a temperature change in the grain when the grain stays on a grain gathering plate 10.

摘要： PROBLEM TO BE SOLVED: To discriminate abnormality in a burner by making use of external ambient temperature in a grain dryer. SOLUTION: In a circulating grain dryer, a burner 15 is disposed in a duct front 14 opposite to one end of a hot air chamber 5, air for burning operation is blown into the burner 15 via slits in the duct front 14, and an external temperature sensor 16 is arranged at an inlet port of air for burning operation adjoining to a burning section of the burner 15. External temperature data is detected for controlling drying process, average variation in the external temperature is calculated while detecting the external temperature at a predetermined interval in the external temperature sensor 16, and the average variation is compared with a latest detected external temperature. If the external temperature rises to a predetermined temperature level or higher at a predetermined period of time, the burner is discriminated to be in abnormal burning operation and the burner 15 is stopped.

摘要： PROBLEM TO BE SOLVED: To enhance detection accuracy of the outer air temperature sensor of a circulation grain dryer. SOLUTION: In a circulation grain dryer, an outer air inlet box 18 is disposed above a duct front 14 facing the hot air chamber 5 of a drying chamber 2, a burner 15 is disposed in the duct front 14 and a large number of slits 19, 19, ... are made in the upper surface 14a and the left/right side faces 14b, 14b of the duct front 14 so that outer air flows in through the slits 19, 19, ... An outer air temperature sensor 16 is disposed above the upper surface 14a of the duct front 14 at a part where the outer air passes toward the slits 19, 19, ...Since the effect of combustion heat from the burner 15 on the outer air temperature sensor 16 is reduced, temperature detection can be stabilized and since the outer air temperature sensor 16 can detects an extremely high temperature, failure of a suction fan for circulating drying air can also be detected.

摘要： PROBLEM TO BE SOLVED: To suitably control in a filling-up mode based on a load detection of a drive motor at the time of grain flowing. SOLUTION: The grain dryer comprises a feeding motor for driving a feeding mechanism based on a drive switch operation, a drive motor for driving other grain circulating mechanism and an exhausting unit, a structure for switching the feeding motor and the drive motor to drive states so that a grain to be dried can be filled up in this state, and a motor load detecting means for detecting loads of the drive motor. In this case, when a predetermined overload is exhibited based on a detected result of the detecting means, the feeding motor is controlled to be stopped. Then, after a predetermined time is elapsed after the drive motor is stopped or when the load of the drive motor is reset to a predetermined value or less, the feeding motor is reset to be driven.

摘要： PURPOSE:To improve the accuracy of grain moisture at the time of delivery, by determining the amplitude of a waveform width of a moisture signal voltage when the maximum value of the voltage is outside allowance limits, and by taking in said maximum value as the data for calculation of the moisture when the waveform width is larger than a prescribed value. CONSTITUTION:Measuring electrode rolls 1 are rotated by the drive of a motor 8 of a moisture meter, grains are supplied one by one to the rolls 1, and a moisture signal voltage E corresponding to one grain is outputted from a resistance-voltage conversion circuit 2. This voltage E is subjected to A/D conversion 4, and the maximum value M is detected out of converted values thereof and stored 6. In a waveform width detection circuit 3, the rise and fall of the voltage E are detected respectively and a waveform proportional to the size of the grain is determined and stored 6. When the maximum value M is within allowance limits, each maximum value M is taken in as the data for calculation of moisture. When the maximum value M of the voltage E is outside the allowance limits, on the other side, it is taken-in as the data for calculation of the moisture when the detected waveform width of the voltage E that is stored 6 exceeds a value that is set 5, and a mean moisture value is calculated on the basis of these data.

摘要： PURPOSE:To accurately measure the content of water of a grain by forming one of a gap formed between outer peripheral surface parts of detection rolls widely and the other narrowly, and changing the grain guide supply position of a supply guide according to the shape of a dry grain. CONSTITUTION:For example, when the content of water measuring instrument is used for a drying machine, some of grains being dried are sent to the conveying device of a water measuring instrument and then supplied to the supplying guide 1. The grains are sent to the gap 4 between the outer peripheral surface parts of the detection rolls 2 and 3 by the guide 1 and smashed while the water value of the smashed grains is detected. Then when the contents of grain water is detected, the position of supply from the guide 1 to the gap 4 is adjusted according to the kind and grain size of the grains to be dried. Thus, the grains to be dried are supplied from the guide 1 to the best position according to the kind and size of the grains and the smashing state of the grains is made constant.

摘要： PURPOSE:To make the extraction of a shutter easily as well as to facilitate cleaning inside an elevating case, by installing a shutter can which makes the shutter adhere to a bottom port and closes it at a insert process terminal part of the shutter opening or closing the elevating case bottom port. CONSTITUTION:A U-shaped shutter 4 opening or closing a bottom port is installed in the bottom of an elevating case 3 free of insertion. And, in an outer circumferential part of a bottom end of the elevating case 3, there is provided with a U-shaped shutter receiving plate 27 which receives the shutter 4. An upper edge of a projecting wall 25 of this shutter receiving plate 27 is formed into a shutter can part 5 made to come into a gradually up-grade state at a terminal part from an insert process starting end of the shutter 4. Therefore, when the shutter 4 is inserted thereinto, it is lifted up at an insert process terminal part and made to adhere to a bottom opening and closed. Then, it is joined to the receiving plate 27 by a lock bar 29. With this constitution, extraction of the shutter 4 becomes facilitated, thus cleaning for the inside of the elevating case at the time of selecting grain types comes easy.

摘要： PURPOSE:To detect stably the water value of grains by positioning a conveyance roll below a supply device when the water value of grains is detected by a detection roll and moving the conveyance roll from below the supply device when the water value detection is not performed. CONSTITUTION:When a grain water measuring instrument is used as a grain dryer, some of grains which are circulated in the dryer and dried are supplied from the dryer onto the conveyance roll 4 through the supply device and sent into a spiral groove 2 in the outer peripheral surface of the roll 4, one by one, by the spiral groove 2 and a guide plate 5; and they are conveyed and guided along the groove 2 and supplied onto the detection roll 6, which detect the water value of crushed grains repeatedly at specific time intervals while crushing the grains. Remaining grains which are not sent in the groove 2 fall from a spiral groove 3 and returned into the dryer, so that they are circulated and dried together with grains in the dryer. Further, when the water value of the grains is not detected, the roll 4 moves from below the supply device and grains supplied from the supply device are not send in the groove 2, but returned into the dryer through a grain water measuring instrument and dried together with grains in the dryer.
