A relative humidity detection sensor 46 is installed near the exhaust port 33 of the drying chamber unit 12 to detect the relative humidity of the exhaust discharged from the exhaust port 33.

  A method of using the dryer configured as described above and a method of controlling drying will be described below with reference to FIGS.

  When the yield is small and only one drying chamber unit 12 is sufficient, one drying chamber unit 12 is fixed or connected to the hot air generator 11. The drying chamber unit 12 accommodates the drying tray 3 in which shiitake mushrooms are arranged in the drying chamber 25 in advance. The drying chamber unit 12 is moved on the rail 27 in a state where the door 29 is closed, and is fixed or connected to the hot air generating device 11 by the attaching / detaching bracket 42. The hot air branch 37 and the hot air junction 39 of the drying chamber unit 12 are closed by the respective shut-off dampers 38 and 40.

  The drying process of shiitake is roughly divided into early, middle and late stages. Adjust the displacement and drying temperature at each stage.

  In the initial stage of drying, the air supply and exhaust ports are fully opened so that the exhaust amount becomes the maximum amount. As shown in FIG. 4, the opening amount of the intake damper 23 is maximized, the intake port 21 is fully opened, and the hot air circulation port 35 is fully closed. The drying start temperature is 40 to 45 ° C.

  By driving the blower 17, the outside air is taken into the hot-air generator 11 from the outside air inlet 20 through the fully opened inlet 21. Then, the hot air is dried by the furnace 15 and the heat exchanger 16 heated by the flame of the burner 14, passes through the hot air outlet 22 and the hot air inlet 30, and passes from the lower space of the drying chamber unit 12 to the rectifying plate 32. It blows up from the bottom through the hole 32a. Meanwhile, heat is given to shiitake to evaporate the water. The maximum amount of intake air is exhausted from the fully open exhaust port 34 to the outside by opening the ceiling exhaust damper 33 to the maximum. Meanwhile, the relative humidity sensor 46 installed near the exhaust port 34 detects the relative humidity around the exhaust port 34 and sends a detection signal to the control panel 18. As time passes, as shown in the graph of FIG. 10, the relative humidity around the exhaust port 34 decreases smoothly from the initial 90% level.

When the middle stage of drying is reached and the relative humidity around the exhaust port 34 reaches a set value of 30% or less as shown in the graph of FIG. 10, the control panel 18 is driven based on the detection signal from the relative humidity sensor 46. A control signal is sent to the motor, and, as shown in FIG. 5, the opening amount of the intake damper 23 is halved, and both the intake port 21 and the hot air circulation port 35 are opened by half. Exhaust amount from the exhaust port 3 4 1/2, 1/2 of the total amount of hot air sent to the drying chamber 25 is taken from the intake port 2 1, 1/2 is circulated through the hot air circulation port 35. The exhaust damper 33 is halved as the wind pressure decreases, and closes the exhaust port 34 half. As a result, only the amount taken from the intake port 21 is exhausted outside the machine. Thereafter, the relative humidity of the exhaust from the exhaust port 34 decreases with time. When the set value reaches 15% or less, based on the detection signal from the relative humidity sensor 46, the control panel 18 sets the intake damper 23 to 1/3 opening.

  In the late drying stage, the air supply and exhaust ports are fully closed, and the air in the machine is fully circulated. When the relative humidity of the exhaust gas from the exhaust port 34 becomes 10% or less, based on the detection signal from the relative humidity sensor 46, the intake damper 23 is set to the minimum opening by the control signal from the control panel 18 as shown in FIG. The intake port 21 is fully closed, and the hot air circulation port 35 is fully opened. The wind pressure with respect to the exhaust damper 33 returns below the set pressure, and the exhaust port 34 is fully closed. As a result, almost all the air in the machine circulates. If no change in humidity is observed for 2 to 3 hours thereafter, the drying operation is stopped.

  A series of control operations from the start to the end of drying as described above can be executed by a selection program incorporated in the control panel 18. The user can execute the automatic operation by arbitrarily selecting a program in a dry matter state from a plurality of dry programs prepared. As a selection program, there is a program and small fish for Hiyoko for drying shiitake mushrooms (small shiitake mushrooms that don't get wet in the rain and with little water) and Amiko (it's a big shiitake mushrooms that gets wet in the rain and has a lot of water) Prepare a program for drying.

  Next, when the yield is large and one drying chamber unit 12 is insufficient, the drying chamber unit 12 is added. The succeeding drying chamber unit 12 is fixed to or coupled to the leading drying chamber unit 12 by means of a detachable fitting 42. The hot air branch port 37 and the hot air junction port 39 of the head drying chamber unit 12 are fully opened by depressing the respective shut-off dampers 38 and 40, thereby allowing the drying chamber units 12 and 12 to communicate with each other. On the other hand, the hot air branch port 37 and the hot air junction port 39 of the subsequent drying chamber unit 12 are fully closed by raising the respective shut-off dampers 38 and 40. 7 shows a state in which the air supply / exhaust port is fully opened in the initial stage of drying, FIG. 8 shows a state in which the air supply / exhaust port is half open in the middle of drying, and FIG.

  As shown in each figure, part of the hot air introduced from the hot air generator 11 to the lower part of the head drying chamber unit 12 passes through the hot air branch port 37 and the hot air inlet 30 at the lower part of the subsequent drying chamber unit 12. Then, the water is branched and supplied to the lower space of the subsequent drying chamber unit 12, and the inside of the subsequent drying chamber unit 12 is blown up from the bottom to the top. As a result, the two drying chamber units 12 can be combined and dried efficiently. In the initial stage of drying shown in FIG. 7, the entire amount is discharged from the exhaust port 34 of each drying chamber unit 12 to the outside of the machine, and in the middle stage of drying shown in FIG. 8, the hot air flows through the hot air return port 36 and the hot air circulation port 35. A half of the total amount is circulated with the generator 11. In the later stage of drying shown in FIG.

  Further, by combining the two drying chamber units 12, it is possible to perform drying in accordance with the dry matter state. For example, the first drying chamber unit 12 can be used for a large amount of Moe Shiitake with a large amount of moisture, and the subsequent drying chamber unit 12 can be used for a small amount of Hywa Shiitake with a small amount of water, and these can be dried at the same time.

  For example, when the air volume adjustment damper 31 of the hot air introduction port 30 of the head drying chamber unit 12 is turned down and fully opened, and the air volume adjustment damper 31 of the hot air introduction port 30 of the subsequent drying chamber unit 12 is erected to be half open, It is possible to increase the amount of hot air that blows up the interior of the first drying chamber unit 12 from the bottom to the top, and to reduce the amount of hot air that blows up the interior of the subsequent drying chamber unit 12 from the bottom to the top. In this manner, by adjusting the air volume in each drying period (initial stage, middle period, and late stage) in units of units, the dry matter stored in the head drying chamber unit 12 and the dry matter stored in the subsequent drying chamber unit 12 are adjusted. The drying operation based on the optimal air volume adjustment according to the state becomes possible.

  The dryer according to the present invention can be used as a dryer for crafts such as bamboo products and dried flowers in addition to drying agricultural and fishery products and processed products.
