The material to be dried is dried by the circulating air.

  In this air circulation, the area of the vent holes 33, 33, 33 of the left side panels 30A, 30B, 30C is small, and the area of the vent holes 43, 43, 43 of the right side panels 40A, 40B, 40C is large to some extent. The air velocity flowing into the drying chamber SP4 from the vent holes 33, 33, 33 is high, and the air in the drying chamber SP4 smoothly passes through the vent holes 43, 43, 43. The object is dried by air flowing from left to right at a substantially constant speed, and the object to be dried is appropriately dried. Further, the size of the vent holes 43, 43, 43 of the right side panels 40A, 40B, 40C is increased toward the lower side. In this case, if the size of the vent holes 43, 43, 43 of the right side panels 40A, 40B, 40C is the same, the air resistance becomes smaller in the vent hole 43 located on the upper side near the suction port 63, and the drying chamber SP4. Much of the air flowing inside is directed toward the upper vent hole 43 having a small resistance. However, in this embodiment, by increasing the size of the vent hole 43 as it goes downward, the air resistance of all the vent holes 43 is made substantially the same, and the air flowing in the drying chamber SP4 flows from the left to the right side. It flows smoothly in the direction. Therefore, also in this respect, the material to be dried is appropriately dried.

  Further, when the internal temperature reaches the upper limit temperature that is higher than the predetermined drying set temperature by a predetermined temperature, the energization to the heater 52 is cut off, and the temperature of the circulating air gradually decreases. The internal temperature also decreases. When the internal temperature reaches the lower limit temperature that is lower than the set temperature by a predetermined temperature, the heater 52 is energized again and the circulating air is heated to raise the temperature, and the internal temperature gradually increases accordingly. . Thereafter, the internal temperature is maintained substantially at the set temperature by intermittent energization control of the heater 52. Therefore, the material to be dried in the drying chamber SP4 is appropriately dried.

  Further, during the operation of the dryer, a deodorizing heater (not shown) of the deodorizing unit 53 is energized to raise the temperature of the catalyst (not shown), and the oxidative decomposition of the odor component starts from the state where the temperature of the catalyst reaches about 80 ° C. When the temperature rises to about 300 ° C., complete combustion decomposition takes place. If the amount of air passing through the deodorizing unit 53 is large, it becomes difficult to maintain the temperature of the catalyst at about 300 ° C. Therefore, the area of the ventilation port 29a on the suction side of the deodorizing unit 53 is made relatively small, and the deodorizing unit 53 The amount of air passing through is limited.

  When drying of the object to be dried is completed in this way, the operator rotates the front wall 11 to open the front wall 11, and the tray receiver 34 and the right side panels 40A, 40B of the left side panels 30A, 30B, 30C. , 40C, the tray 80 placed and supported on the tray receiver 44 is taken out. Then, the object to be dried in the tray 80 is taken out. Thereafter, a new object to be dried is accommodated in the tray 80, and the tray 80 is placed on and supported by the tray receivers 34 and 44. And the front wall 11 is closed as mentioned above, and drying of a to-be-dried object is restarted. Through such operations and operations, the objects to be dried are sequentially dried.

  When such an object to be dried is repeatedly performed, the inside of the dryer, in particular, the walls of the ventilation paths SP1 and SP2 and the drying chamber SP4, that is, the flat plate portion 21a and the mounting portions 21b and 21c of the left mounting member 21, and the right mounting. The flat plate portion 22a and mounting portions 22b and 22c of the member 22, the inner surface of the front wall 11, the inner surface of the back wall 12, the inner surface of the lower surface wall 16, the inner surface of the upper plate 27, the left side panels 30A, 30B and 30C, Dirt adheres to the right side panels 40A, 40B, 40C and the like. When the dryer is used for a certain period of time in order to clean such dirt, the left side panel 30A, 30B, 30C and the right side panel 40A, after the tray 80 is taken out from the housing 10 are removed. 40B and 40C are removed from the left side mounting member 21 and the right side mounting member 22, respectively.

  In removing the left side panels 30A, 30B, 30C, first, the left side panel 30A is lifted so that the upper pins 23a, 24a are positioned below the through holes 31, 32, and then the left side panel 30A is moved to the right side. The upper pins 23a, 24a are disengaged from the through holes 31, 32 by moving to the left side panel 30A from the left mounting member 21. Next, by engaging the left side panel 30B with the through holes 31 and 32 of the middle pins 23b and 24b by the same operation as that of the left side panel 30A, the left side panel 30B is detached from the left mounting member 21. Remove. Finally, the left side panel 30C is released from engagement with the through holes 31 and 32 of the lower pins 23c and 24c by the same operation as the case of the left side panel 30A, and the left side panel 30C is moved to the left mounting member. Remove from 21. As described above, the left side panels 30A, 30B, and 30C are removed in this order because the lower end of the left side panel 30A is engaged with the upper end of the left side panel 30B so as to overlap. This is because the lower end portion of 30B overlaps and engages with the upper end portion of the left side panel 30C.

  In the removal of the right side panels 40A, 40B, 40C, as in the case of the left side panels 30A, 30B, 30C, the through holes 31 of the upper pins 25a, 26a, the intermediate pins 25b, 26b, and the lower pins 25c, 26c, The right side panels 40A, 40B, and 40C are removed from the right side mounting member 22 in this order. Also in this case, the right side panels 40A, 40B, and 40C are removed in this order because the lower end of the right side panel 40A is engaged with the upper end of the right side panel 40B so as to overlap. This is because the lower end of 40B overlaps and engages with the upper end of the right side panel 40C.

  After removing the left side panels 30A, 30B, and 30C and the right side panels 40A, 40B, and 40C from the left side mounting member 21 and the right side mounting member 22 in this way, the operator cleans dirt inside the dryer. In particular, the walls of the ventilation paths SP1 and SP2 and the drying chamber SP4, that is, the flat plate portion 21a and the mounting portions 21b and 21c of the left mounting member 21, the flat plate portion 22a and the mounting portions 22b and 22c of the right mounting member 22, The dirt adhering to the side surface, the inner surface of the back wall 12, the inner surface of the lower wall 16, the inner surface of the upper surface plate 27, etc. is washed. Simultaneously with this cleaning, the fallen objects falling in the interior of the housing 10, particularly in the ventilation paths SP1 and SP2 and the drying chamber SP4 are also removed. Further, the operator also cleans the dirt adhering to the removed left side panels 30A, 30B, 30C and right side panels 40A, 40B, 40C.

  By such washing and removal of fallen objects, inside the dryer, in particular, the walls of the ventilation paths SP1 and SP2 and the drying chamber SP4, that is, the flat plate portion 21a and the mounting portions 21b and 21c of the left mounting member 21, and the right mounting member 22 Plate portion 22a and mounting portions 22b and 22c, the inner surface of the front wall 11, the inner surface of the back wall 12, the inner surface of the lower wall 16, the inner surface of the upper plate 27, the left side panels 30A, 30B, and 30C, the right side It is preferable in terms of hygiene because generation of mold, growth of bacteria, etc. in the panels 40A, 40B, 40C and the like can be prevented.

  After the left side panels 30A, 30B, 30C and the right side panels 40A, 40B, 40C are cleaned, the left side panels 30A, 30B, 30C and the right side panels 40A, 40B, 40C are replaced with the left side mounting member 21 and the right side mounting member 22. Attach to. When attaching the left side panels 30A, 30B, 30C, first hold the left side panel 30C, the lower portions of the through holes 31, 32 are opposed to the lower pins 23c, 24c, and the left side panel 30C is moved to the left side. The tips of the lower pins 23c, 24c are passed through the through holes 31, 32. Thereafter, the operator moves the left side panel 30C downward, engages the upper portions of the through holes 31, 32 with the lower pins 23c, 24c, and suspends the left side panel 30C to the lower pins 23c, 24c. Next, the left side panel 30B is suspended from the middle pins 23b and 24b by the same operation as that of the left side panel 30C. In this case, the upper end portion of the left side panel 30C is inserted into the gap between the lower end portion of the left side panel 30B and the lower end portion of the vertical portion 34a of the lowermost tray receiver 34.

  Next, the operator suspends the left side panel 30A from the upper pins 23a and 24a by the same operation as that of the left side panel 30C. Also in this case, the upper end portion of the left side panel 30B is inserted into the gap between the lower end portion of the left side panel 30A and the lower end portion of the vertical portion 34a of the lowermost tray receiver 34. As described above, the left side panels 30C, 30B, and 30A are attached in this order by overlapping and engaging the lower end of the left side panel 30B with the upper end of the left side panel 30C and the left side panel 30A. This is because the lower end portion of the left side panel 30B is overlapped with and engaged with the upper end portion of the left side panel 30B.

  The right side panels 40C, 40B and 40A are attached to the lower pins 25c and 26c, the middle pins 25b and 26b and the upper pins 25a and 26a in this order in the same manner as the left side panels 30C, 30B and 30A. The right side panels 40C, 40B, 40A are suspended and attached to the attachment portions 22b, 22c of the right attachment member 22. Also in this case, the right side panels 40C, 40B, 40A are attached in this order in such a manner that the lower end of the right side panel 40B is overlapped and engaged so as to face the upper end of the right side panel 40C, and the right side panel 40A. This is because the lower end portion of the right side panel 40B is overlapped with and engaged with the upper end portion of the right side panel 40B. Thus, after attaching left side 30A, 30B, 30C and right side panel 40A, 40B, 40C to left attachment member 21 and right attachment member 22, respectively, it dries a new thing to be dried using a drier. Is possible.

  In drying the object to be dried, standard left side panels 30A, 30B, and 30C were attached to the left attachment member 21 of the dryer so that the object to be dried was dried. However, depending on the type of the object to be dried, the left side panels 30D, 30E as shown in FIGS. 10A, 10B, and 10C can be used instead of any or all of the left side panels 30A, 30B, 30C. , 30F can be selectively attached to the left attachment member 21 to dry the object to be dried. In this case, if the size of the ventilation holes 33 (total area of the plurality of ventilation holes 33) of the left side panels 30A, 30B, 30C, 30D, 30E, and 30F is small, the static pressure of the air in the ventilation path SP1 increases. The air velocity discharged from the vent hole 33 into the drying chamber SP4 (tray 80) is increased. Conversely, if the size of the vent holes 33 (total area of the plurality of vent holes 33) of the left side panels 30A, 30B, 30C, 30D, 30E, and 30F is large, the static pressure of the air in the ventilation path SP1 is increased. The air velocity discharged from the vent hole 33 into the drying chamber SP4 (tray 80) is lowered.

  When the object to be dried is a heavy object such as fish or meat, it is preferable that the air velocity is high. On the other hand, when the object to be dried is a light object such as a leaf or thin vegetable, it is preferable that the air velocity is low. Further, if the size, shape, position, or total area of the vent holes 33 of the left side panels 30A, 30B, 30C, 30D, 30E, and 30F are different, there is a difference in the air flow in the drying chamber SP4 (tray 80). Arise. Therefore, various objects to be dried can be appropriately dried by selectively attaching the left side panels 30A, 30B, 30C, 30D, 30E, and 30F to the left attachment member 21 according to the type of the object to be dried. it can. Note that the left side panels 30D, 30E, and 30F are configured in the same manner as the left side panels 30A, 30B, and 30C with respect to portions other than the vent hole 33, and therefore, the left side mounting members 21 of the left side panels 30D, 30E, and 30F. The attachment and detachment with respect to is performed in the same manner as the left side panels 30A, 30B, 30C.

  In the dryer according to the embodiment configured and operated as described above, the upper pin 23a of the left attachment member 21 is inserted into the through holes 31, 32 of the left side panels 30A, 30B, 30C, 30D, 30E, 30F. The left side panels 30A, 30B, 30C, 30D, 30E, 30F are connected to the upper pins 23a, 24a, the middle pins 23b, 24b by penetrating the 24a, middle pins 23b, 24b and the lower pins 23c, 24c. The left side panels 30A, 30B, 30C, 30D, 30E, and 30F are attached to the left side mounting member 21 by being suspended from the lower pins 23c and 24c. Further, the upper pins 25a, 26a, the middle pins 25b, 26b and the lower pins 25c, 26c of the right attachment member 22 are passed through and engaged with the through holes 41, 42 of the right side panels 40A, 40B, 40C. The right side panels 40A, 40B, and 40C are suspended from the upper stage pins 25a and 26a, the middle stage pins 25b and 26b, and the lower stage pins 25c and 26c, and the right side panels 40A, 40B, and 40C are attached to the right side mounting member 22. . Therefore, the left side panel 30A, 30B, 30C, 30D, 30E, 30F and the right side panel 40A, 40B, 40C can be easily attached to and detached from the left side mounting member 21 and the right side mounting member 22, respectively. The left side panels 30A, 30B, 30C, 30D, 30E, 30F and the right side panels 40A, 40B, 40C can be easily cleaned.

  Further, the left attachment panel 21 is provided with divided left side panels 30A, 30B, 30C, 30D, 30E, and 30F, and the right attachment member 22 is provided with divided right side panels 40A, 40B, 40C is attached. Therefore, even if the left side panels 30A, 30B, 30C, 30D, 30E, and 30F and the right side panels 40A, 40B, and 40C are relatively heavy members, such as iron plates and stainless steel plates, the left side panels 30A and 30B. , 30C, 30D, 30E, 30F and the right side panels 40A, 40B, 40C can be configured relatively lightly. Accordingly, the left side panels 30A, 30B, 30C, 30D, 30E, 30F and the right side panels 40A, 40B, 40C can be easily removed from the left side mounting member 21 and the right side mounting member 22, and the left side mounting member 21 and It can be easily attached to the right attachment member 22.

  Furthermore, in the dryer according to the embodiment, the left side panels 30A, 30B, 30C, 30D, 30E, and 30F, and the left side panels 30A, 30B, and 30D other than the lowermost of the right side panels 40A, 40B, and 40C. , 30E, 30F and the right side panels 40A, 40B, the lower end portions thereof overlap with the upper end portions of the left side panels 30B, 30C, 30D, 30E, 30F and the right side panels 40B, 40C, respectively. Thus, it was made to attach with respect to the left side attachment member 21 and the right side attachment member 22. According to this, a gap between a pair of left side panel and right side panel located adjacent to each other in the vertical direction can be eliminated, and the passage of the left side panels 30A, 30B, 30C, 30D, 30E, and 30F from the ventilation path SP1. Air can accurately flow into the drying chamber SP4 (tray 80) through the air holes 33, and dry from the drying chamber SP4 (tray 80) through the vent holes 43 of the right side panels 40A, 40B, and 40C. The air in the chamber SP4 (tray 80) can be accurately discharged to the air passage SP2.

  The implementation of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the object of the present invention.

  In the dryer according to the above-described embodiment, as described above, the air resistance decreases toward the vent holes 43 of the right side panels 40A, 40B, and 40C located on the upper side near the suction port 63, and the air flowing in the drying chamber SP4. Many tend to be directed toward the upper vent hole 43 having a small resistance. In order to prevent the upward air flow, a wind guard may be provided. The wind control guard is composed of, for example, a rectangular plate-like member formed of a metal material such as synthetic resin or stainless steel, and is placed on the upper surface of each tray 80 or on the left side above each tray 80. The surface panels 30A, 30B, 30C, 30D, 30E, 30F and the right side panels 40A, 40B, 40C may be detachably attached. According to this, the air flowing into each tray 80 is diverted downward by the wind control guard without flowing into the upper tray 80. As a result, as compared with the dryer according to the above-described embodiment, the air flows more accurately from the left to the right in each tray 80, and drying of an object to be dried becomes better.

  In addition, when this wind guard is provided, liquids such as seasoning liquid, meat juice, fruit juice, sweetener, boiled juice, etc. and small pieces of the dried material from the dried materials placed in each tray 80 are the bottom plate of the tray 80. Even if it falls downward from the through-hole 81a of the part 81, the wind control guard provided between the tray 80 located below receives the liquid and the small piece. Therefore, the fallen liquid and small pieces are not attached to or mixed with the material to be dried placed on the tray 80 positioned below, and the material to be dried placed on the tray 80 located below is not mixed. It will no longer deteriorate and become defective. And drying seafood, meat, agricultural products, processed foods, etc. at the same time will not affect the objects to be dried placed on other trays 80. Things are obtained. In addition, since the wind guard can be attached and detached, it can clean dirt adhering to the upper surface, can prevent odor from remaining on the wind guard, and can prevent the occurrence of mold and the growth of bacteria. It becomes hygienic.

  In the above embodiment, left side panels 30D, 30E, and 30F other than the standard left side panels 30A, 30B, and 30C are prepared for the left side panel. Although the face panels 30A, 30B, 30C, 30D, 30E, and 30F are selectively used, only the standard right side panels 40A, 40B, and 40C are prepared for the right side panel. However, with respect to the right side panel, the standard right side panels 40A, 40B, and 40C are different from the right side panel having the air holes 43 that differ in at least one of the size, shape, position, and total area. The right side panels 40A, 40B, 40C and the other right side panel may be selectively attached to the attachment portions 22b, 22c of the right attachment member 22 in advance. These right side panels 40A, 40B, 40C and the other right side panels change the air flow in the drying chamber SP4 (tray 80) depending on the size, shape, position or total area of the vent holes 43. Therefore, by selectively using the right side panels 40A, 40B, 40C and the other right side panels, the drying state of the objects to be dried can be changed, and various objects to be dried can be appropriately dried. Become.

  In the above-described embodiment, the left side panels 30A, 30B, and 30C (or 30D, 30E, and 30F) and the right side panels 40A, 40B, and 40C are placed on the left side mounting member 21 and the right side mounting member 22 respectively. I tried to install it. However, instead of this, the number of divisions of the left side panel and the right side panel is further increased, and four or more left side panels and right side panels are attached to the left side mounting member 21 and the right side mounting member 22, respectively. May be. Conversely, the number of divisions of the left side panel and the right side panel may be reduced, and the following left side panel and right side panel may be attached to the left side mounting member 21 and the right side mounting member 22 respectively. In particular, when the height of the dryer (housing 10) is low, the left side panel and the right side panel may be attached to the left side mounting member 21 and the right side mounting member 22 respectively. Further, even in the case of this embodiment and the above-described modification, regarding the number of tray receivers 34 provided on the left side panel and the right side panel, five or more tray receivers other than four or three or less tray receivers are used. You may make it provide.

  In the above embodiment, the through holes 31, 32, 41, 42 provided in the left side panels 30A, 30B, 30C, 30D, 30E, 30F and the right side panels 40A, 40B, 40C are circular at the bottom. And a long hole in the vertical direction in which the upper part is formed into a small-diameter circle. However, the upper pins 23a, 24a, 25a, 26a, the middle pins 23b, 24b, 25b, 26b and the lower pins 23c, 24c, 25c, 26c provided on the mounting members 21, 22 are penetrated and left on the left side in a retaining state. Surface panels 30A, 30B, 30C, 30D, 30E, 30F and right side panels 40A, 40B, 40C are upper pins 23a, 24a, 25a, 26a, middle pins 23b, 24b, 25b, 26b and lower pins 23c, 24c, 25c. 26c, the shape of the through holes 31, 32, 41, 42 may be different from the shape of the above embodiment. For example, a long hole that is long in the vertical direction, such as a triangular shape or a rectangular shape, may be used. The cross-sectional shapes of the upper pins 23a, 24a, 25a, 26a, the middle pins 23b, 24b, 25b, 26b and the lower pins 23c, 24c, 25c, 26c are not circular but are other shapes such as a square shape. Also good.

  In the above embodiment, the shape of the vent holes 33, 43 of the left side panels 30A, 30B, 30C, 30D, 30E, 30F and the right side panels 40A, 40B, 40C is circular or oval. The shape of the pores 33 and 43 may be various shapes other than circular and oval, for example, an ellipse, a quadrangle, and a polygon. Furthermore, in the above embodiment, the sizes and positions of the vent holes 33 and 43 are exemplified by specific numerical values, but the sizes and positions of the vent holes 33 and 43 are changed to various sizes and positions other than those illustrated. Also good.

  Further, in the above embodiment, the left side mounting member 21 and the right side mounting member 22 are provided with the bottom plate portions 21a and 22a, and the bottom plate portions 21a and 22a are tightly fixed to the inner side surfaces of the left side wall 13 and the right side wall 14 respectively. . However, the bottom plate portions 21a and 22a are eliminated, and the mounting portions 21b, 21c, 22b and 22c of the left side mounting member 21 and the right side mounting member 22 are tightly fixed to the inner side surfaces of the left side wall 13 and the right side wall 14. Also good. In this case, the ventilation path SP1 is formed between the inner side surface of the left side wall 13 and the left side panels 30A, 30B, 30C, 30D, 30E, 30F. The ventilation path SP2 is formed between the inner side surface of the right side wall 14 and the right side panels 40A, 40B, 40C.

  Moreover, in the said embodiment, although the tray 80 was comprised in the box shape which consists of the baseplate part 81, side wall part 82,83,84,85, the upper frame 86, the lower frame 87, and the protrusion part 88, plate shape which has a through-hole. The tray 80 may be configured by only the members, that is, the bottom plate portion 81. Further, instead of the flat bottom plate portion 81, a wire net having a through hole through which liquid or the like can pass may be used. A flat wire mesh may be used as the tray 80. That is, the tray 80 is detachably attached to the left side panels 30A, 30B, 30C, 30D, 30E, and 30F and the right side panels 40A, 40B, and 40C, can be easily cleaned, and places an object to be dried. Various members can be used as the tray 80 as long as the member has a through-hole through which liquid from an object to be dried can pass.

  In the above embodiment, the blower 51 sends the air through the deodorizing unit 53, the cooler 65, the cooling fan 67, and the heater 52 to the air passage SP1, and the left side panels 30A, 30B, 30C, from the air passage SP1. Air is allowed to flow into the drying chamber SP4 (tray 80) through the vent holes 33 of 30D, 30E, and 30F, and from the inside of the drying chamber SP4 (tray 80) through the vent holes 43 of the right side panels 40A, 40B, and 40C. Air was allowed to flow out to the ventilation path SP2. However, instead of this, the air flow may be reversed. In other words, the deodorizing unit 53, the cooler 65, the cooling fan 67, the heater 52, and the blower 51 are reversed in the positional relationship in the left-right direction. The air is sent to the ventilation path SP2, and air is caused to flow into the drying chamber SP4 (tray 80) from the ventilation path SP2 through the vent holes 43 of the right side panels 40A, 40B, 40C. From the left side panels 30A, 30B, 30C, 30D, 30E, 30F, the air may flow out to the ventilation path SP1.

  Moreover, in the said embodiment, the heater 52 was provided and the airflow which circulates through ventilation path SP1, drying chamber SP4, ventilation path SP2, space SP3, and cooling chamber SP5 was made into hot air. However, when drying an object to be dried that is not preferable, such as shirasu, the heater 52 may be eliminated and the object to be dried may be dried by cold air or an air flow at a normal temperature.

  Furthermore, in the said embodiment, to-be-dried material was dried with the airflow which circulates ventilation path SP1, drying room SP4, ventilation path SP2, space SP3, and cooling room SP5. However, if the outflow of air to the outside is not a problem, the deodorizing unit 53, the cooler 65, the cooling fan 67, and the like are eliminated, and the air from the outside is blown to the air passage SP1 by the blower 51, and the drying chamber SP4. The air that has flowed into the ventilation path SP2 from inside the (tray 80) may be discharged to the outside from the ventilation path SP2.
