Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drying machine for persimmons, which is used for drying peeled persimmons (so-called peeled fruits) when manufacturing persimmons.

[0002]

2. Description of the Related Art In the Toyama prefecture, when manufacturing persimmons,
Peel the harvested raw persimmon, connect the two peeled fruits with a thread, hang the thread on the dried rod and hang a large number of peeled fruits on the dried rod at appropriate intervals, A method is used in which a dried rod is hung in a well-ventilated outdoor area in a shelf shape and dried in the sun (natural drying), and then finished by briquette drying or electric drying.

Further, recently, in some parts, the sun ray drying sheet 1 is not dried (at all or almost), and as shown in FIG.
A pair of peeled fruits 10 in a box-shaped frame 2 that can be closed with
And a method for directly electrically drying the peeled fruit by a far-infrared heater 12 installed on the inner bottom portion of the frame body 2, in which a large number of drying rods 11 are hung at appropriate intervals in the vertical and horizontal directions (depth direction in the drawing). Machines are also used.

The above-mentioned direct drying method and machine have the effects that the drying period can be greatly shortened and the energy cost can be remarkably reduced as compared with the conventional thermal power drying method using an oil heater. In addition, since far infrared rays penetrate to the center of the persimmon and the whole is dried, it has the advantages that it can completely remove the astringent taste, has a good taste, has a bright color, and has a much longer shelf life than conventional products.

[0005]

However, in the above dryer for persimmon, since the far infrared heater is installed at the bottom of the frame body, when peeled fruits are hung at the same interval in the entire frame body, Far-infrared rays are less likely to reach the peeled fruits and the peeled fruits at the peripheral portion, and the dried state of the peeled fruits may vary, and mold may grow on the peeled fruits at the upper portion or the peripheral portion.

Therefore, as shown in FIG. 2, the peeled fruit 10 is hung only at the central portion of the bottom side drying rod 11 close to the far infrared heater 12, and the peeling fruit 10 is hung to the outer side as far as the upper side drying rod 11. Peeled fruit 1 so that the entire inside has an inverted cone shape
A method of suspending 0 and applying uniform convection heat and far infrared rays to any peeled fruits 10 to eliminate the variation in the dryness is not completely eliminated. In addition, there is a drawback that the number of drying treatments each time is reduced.

Therefore, the present invention has been made based on the above circumstances, and it is possible to efficiently eliminate the variation in the drying condition without impairing the high drying treatment capacity, and to efficiently produce a large amount of good quality persimmons. The purpose is to provide a dryer for use.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, a dryer for persimmon according to the present invention comprises a horizontal main shaft and a driven shaft at the upper and lower portions of a box-shaped frame covered with a heat ray reflective sheet that can be opened and closed. The shaft is supported in parallel with the shaft, a motor with a reducer for rotating the drive shaft is installed in a proper place in the frame, and sprockets are attached to the ends of both shafts. To each endless chain, attach the ring body to the outer peripheral side of each endless chain at appropriate intervals via support pieces,
It is characterized in that a drying rod for hanging a peeled persimmon is hung across horizontally opposed ring bodies, and a far-infrared heater is installed at least at the bottom of the frame body.

[0009]

In the dryer for persimmons according to the present invention, the drying rod is horizontally inserted freely in the ring body provided on the outer peripheral side of the endless chain via the support piece, and when the endless chain rotates in the vertical direction,
The dry pole keeps a certain posture without interlocking with the endless chain,
Persimmons hung on a dry pole are in a constant state without falling.

Further, since the dried rod hanging the peeled persimmon rotates vertically with the endless chain inside the box-shaped frame covered with the heat ray reflective sheet, which persimmon is set by the far infrared heater installed in the frame. Is also heated in the same way, and each persimmon receives far infrared rays from all four directions as well.

Therefore, in this dryer, the persimmons are evenly hung on each of the dried rods supported by the endless chain,
A large amount of persimmon can be dried quickly and evenly.

[0012]

EXAMPLES Hereinafter, the dryer for persimmons according to the present invention will be described in detail. As shown in FIG. 1, the dryer of the present invention supports a horizontal driving shaft 3 and a driven shaft 4 in parallel in the upper and lower parts of a box-shaped frame body 2 covered with an openable / closable heat ray reflection sheet 1 to form a frame. A motor 5 with a reducer for rotating the driving shaft 3 is installed at a proper position in the body 2, and a sprocket 6 is attached to the end portions of both shafts 3 and 4, and a sprocket corresponding to the vertical direction of both shafts 3 and 4 is installed. An endless chain 7 is hung between 6 and 6, and an annular body 9 is attached to the outer peripheral side of each endless chain 7 at appropriate intervals via support pieces 8 so as to straddle the annular bodies 9 and 9 facing each other in the horizontal direction. A dry rod 11 for hanging the persimmon 10 after peeling is loosely inserted, and a far-infrared heater 12 is installed at least at the bottom of the frame 1.

Here, the heat ray reflection sheet 1 has heat rays (mainly far infrared rays) on the inner surface side of a synthetic resin sheet having excellent heat resistance.
In order to reflect well, processing such as vapor deposition of metal aluminum is performed to form a shape slightly larger than that according to the outer shape of the box-shaped frame body 2, and a slide fastener 13 for opening and closing is formed.
Is attached. A surface fastener or the like may be used instead of the slide fastener 13 for opening and closing the heat ray reflective sheet 1.

The frame body 2 is assembled in a vertically long box shape by using an angle plate or the like, a bottom wall 14 is provided at the bottom portion, and horizontal frames 16 are attached to the upper and lower portions of both side surfaces so as to face each other. . A far-infrared heater 12 is installed in the center of the bottom wall 14, and a motor 5 with a speed reducer is installed in the periphery of the heater.
Further, bearings 15 for the driving shaft 3 and the driven shaft 4 are fixed to the horizontal frames 16 facing the upper and lower portions of both side surfaces.

The motor 5 with reduction gear and the driving shaft 3 are connected via a power transmission member 17 such as an endless chain (or belt), and the motor 5 with reduction gear is turned on to connect the driving shaft 3 with the driving shaft 3. The endless chain 7 and the driven shaft 4 rotate slowly together with the sprockets 6 of the shafts 3 and 4.

Further, the far-infrared heater 12 has a side surface (a lateral side for fixing the bearing 15 mentioned above) facing not only the bottom portion but also the vertically moving rod 11 along the rotation direction of the endless chain 7 in order to accelerate drying. (It is different from the side surface provided with the frame 16) or the ceiling part.

The dryer of the present invention has the above-mentioned structure. In use, first, a large number of peeled persimmons 10 connected by two threads are prepared, and the slide fastener 13 is lowered to obtain the heat ray reflective sheet 1. Open, and hang the prepared persimmons 10 on the dried pole 11 at a reasonable height. When the dried pole 11 is full, rotate the endless chain 7 a little and move to the next empty dried pole 11. Is moved to an appropriate height, the persimmons 10 are also hung on the dried poles 11 at appropriate intervals over the entire length, and this is repeated in order, and the persimmons 10 are evenly hung on all the dried poles 11.

Alternatively, a set of two pairs of persimmons 10 connected by a thread are hung on a drying rod 11 at appropriate intervals over the entire length in advance, and the required number of the drying rods 11 are horizontally opposed to each other. The rings 9 and 9 are inserted one after another. Also in this case, the endless chain 7 is rotated little by little and the next drying rod 11 is rotated.
The ring bodies 9 to be inserted are moved to an appropriate height.

After the persimmon 10 has been hung, the heat ray reflective sheet 1
Closed, switch on the motor 5 with reduction gear and the far-infrared heater 12, and slowly rotate the persimmon 10 hanging on the drying rod 11 together with the endless chain 7 in the vertical direction,
It is dried by hot air (convective heat) emitted from the far infrared heater 12 and heat rays (far infrared).

In this case, all the persimmons 10 rotate up and down in the frame 2 and receive the hot air from the far infrared heater 12 equally well. Further, the heat ray is repeatedly reflected in the frame body 2 by the heat ray reflection sheet 1, and any persimmon 10 receives the heat ray from all sides. Therefore, if the dryer of the present invention is used, a large amount of persimmons can be dried quickly without variation.

[0021]

As described above, the drying machine for persimmons according to the present invention is provided with a pair of endless chains which vertically rotate in a box-shaped frame covered with a heat ray reflecting sheet, and removes the persimmons after peeling. A large number of hanging drying poles are horizontally pivoted by an annulus attached to both endless chains at appropriate intervals, a far infrared heater is installed at least at the bottom of the frame, and the endless chain is dried by the far infrared heater while rotating. Since the persimmons of the poles are dried, even if the persimmons are evenly applied to each of the dried poles, all the persimmons receive the heat and heat rays of the far-infrared heater equally and dry without variation.

Therefore, unlike the conventional dryers, it is not necessary to hang the persimmons in an inverted conical shape leaving a useless space in the dryer in order to eliminate the variation in drying, and a large amount of persimmons are dried. It is possible to hang it evenly inside the machine and dry it quickly and evenly, and it is possible to efficiently produce high quality persimmons.
