[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dryer for foods, particularly a dryer suitable for drying a mainspring.

[0002]

[Prior art and its problems]

 Conventionally, as a mainspring dryer, a processing cylinder, which is ventilated through a mesh stretched around the circumference of the cylinder as shown in Japanese Patent Publication No. 59-29206, is rotatably mounted on a shaft, and a bonfire is fired from the lower part of the processing cylinder. Hot air and smoke are introduced into the processing cylinder to dry the mainspring, and a winder that causes wind due to the rotation of the processing cylinder is attached to the outer periphery of this processing cylinder, and this ventilation body promotes ventilation into the processing cylinder. There is something like this. In addition, the one previously proposed by the present applicant in Japanese Patent Application No. 3-234020 is that a crosspiece parallel to the axis of one or more rotary drums is provided in the rotary drum whose outer periphery is formed of a steel plate and is attached to the rotary drum. Hot air is supplied from one of the rotating drums from a heat exchanger with adjustable temperature, discharged from the other, and the mainspring in the rotating drum is dried by scraping and dropping the mainspring in the rotating drum. .

The former of the above-mentioned conventional devices uses hot air from a bonfire as a heat source for drying the mainspring, and the labor required to replenish the wood for the bonfire or to control the temperature for that purpose is undeniable. Since a single dryer dries red, blue, and green, there are 3 types of drying methods. Since the processing cylinder is made of porous plates, part of the main body is inside the holes. The mainspring may be damaged by the rotation of the processing cylinder when it is inserted into the machine, and there is also a problem in taking it out because there is a bonfire at the bottom of the processing cylinder.

Further, in the latter of the conventional devices, since the rotary drum is formed of a steel plate, when the mainspring scraped by the rotation of the rotary drum is dropped by the crosspiece during drying, it directly drops onto the steel plate. Since there is no shock absorber, the mainspring that has fallen may be damaged.Furthermore, since no consideration was given to the relationship between the mounting of the crosspiece and the hot air that is supplied, the mainspring that was thrown into the rotating drum was totally damaged. However, there is a problem that the drying mode is not performed in the same state.

[0005]

[Problems to be solved by the device]

 The present invention solves the above-mentioned problems of the conventional device, improves the drying efficiency, prevents the mainspring from being damaged during drying, and ensures that the entire mainspring in the rotary cylinder is uniformly dried. The purpose is to provide a mainspring dryer with improved commercial value.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the mainspring dryer according to the present invention is a mainspring dryer in which hot air for drying is supplied from one side of the rotary drum and sucked from the other side, and the inner circumference of the rotary drum is A large number of bamboo racks are laid side by side on the entire circumference of the surface and fixed, and three strips for scraping the material to be dried are evenly spaced from the upper part of the bamboo rack with a predetermined inclination angle with the axial direction of the rotating cylinder. When the objects to be dried inside the rotary drum are scraped up by the above-mentioned objects for scraping up the objects to be dropped and fall, they are dropped onto the bamboo racks in the areas divided by the above-mentioned bars. It is characterized in that the number of rotations of the rotating drum is controlled, and that the inclination of the bar for scraping the dried object is an inclination in the direction of blocking the flow of hot air for drying. is there.

[0007]

[Action]

 In the mainspring dryer according to the present invention, bamboo bamboo is laid on the entire inner circumference of the rotary cylinder, so that the axis of the rotary cylinder is evenly spaced on the inner circumference of the rotary cylinder at the time of drying and in the direction of blocking the flow of hot air for drying. The mainspring, which is scraped up by the three scraping bars for the material to be dried that are inclined with respect to and falls from the approximate center of the upper part of the rotating cylinder, falls on the bamboo rack on the inner circumference of the rotating cylinder. There is no risk of damaging the mainspring by being buffered. In addition, since each bar for scraping the dried object attached to the inner circumference of the rotary drum is inclined in a direction that blocks the flow of the hot air for drying, the mainspring scraped by the bar is heated by the suction force of the hot air. There is no danger of being attracted to the discharge side of the rotating drum, and it is made to fall from the approximate center of the upper part of the rotating drum. Furthermore, when the mainspring scraped up by the inclined bar falls, Since the mainspring does not fall at the same time, the falling mainspring is scattered by the hot air and can be dried efficiently.

[0008] Furthermore, the rotation of the rotary drum during drying is such that when the main body scraped up by the three bars falls, it falls into an area defined by the three bars. Since the speed was controlled, the mainspring etc. that fell could be scraped up immediately by the next crosspiece, which could be carried out efficiently.

The outer plate 24 having an opening for the take-out door 9 is provided on the outer periphery of the bent piece 13 on the peripheral edge of the side plate 12 on the motor 8 side and the peripheral bent piece 15 on the side plate 18 on the hot air side. Is fixed by rivets or the like to form the rotary cylinder 1.

A large number of bamboo pieces are divided in the longitudinal direction on the entire inner peripheral wall of the outer plate 24 forming the above-described rotating body 1, and the upper surfaces of the divided pieces are each shaped like an instep (hereinafter referred to as bamboo pieces). 25, 25, 25, ... are laid side by side in the longitudinal direction and fixed, and further, avoiding the opening of the take-out door 9 of the rotating body 1 and dividing the rotating body into three equal parts. The bars 26a, 26b, and 26c for scraping the dried object, which are inclined with respect to the axis so as to block the flow direction of the hot air over the entire width of the rotary cylinder 1 in the axial direction, are used as the bamboo racks 25, 25, ...・ ・ Fixed from the upper surface. The fixing means is provided with a plurality of bolt holes in each of the crosspieces, and the bolts 27 are inserted through the bolt holes and the holes formed in the outer plate 24 to fix the bolts from the outside of the rotary drum 1 with nuts. ing. Further, the height of the crosspiece has a height required to scrape the mainspring.

A mirror plate 20 fixed to the frame 2 by a mounting portion 35 is loosely fitted in the opening 16 of the side plate 18 on the hot air side, and a wire mesh 30 is stretched below the mirror plate 20. Further, a hot air supply opening 31 is opened, and an inspection port 32 and a mainspring supply shoot opening 33 are formed in the upper part. Then, the hot air from the heat exchanger 5 is supplied into the rotary cylinder 1 through the hot air opening 31 described above, and the hot air is sucked by the rotation of the fan 6 provided on the motor 8 side.

Further, the main shaft 4, which is fixed to the side plate 12 on the motor side of the rotary drum 1 via the main shaft support plate 19, is rotatably supported by the frame 2 via bearings, and the side plate 18 on the hot air side of the rotary drum 1 is flat. Since the portion 17 is rotatably supported by the cylinder receiving roller 3 mounted on the frame 2, the rotary cylinder 1 is rotated by the main shaft 4 and its rotation is rotatably supported by the cylinder receiving roller 3. Therefore, the rotation is extremely smooth. Further, the rotation speed of the rotary cylinder 1 can be changed by a normal transmission mechanism.

Since the mainspring dryer according to the present embodiment is configured as described above, a predetermined amount of mainspring, which is an object to be dried, is put into the rotary drum 1 from the mainspring supply chute 10 to drive the motor 8 and the heat exchanger. 5, the motor 8 is operated to rotate the rotary drum 1 at a predetermined rotational speed and the fan 6 to rotate the hot air from the heat exchanger 5 through the opening 31 of the end plate 20 on the hot air side of the rotary drum 1. The air is supplied into the rotary drum 1, sucked by the fan 6 in the axial direction of the rotary drum 1, hot air is blown to the mainspring in the rotary drum 1, and the hot air is discharged to the outside of the machine.

On the other hand, the mainspring introduced into the rotary drum 1 is attached to the three bars 26a, 26b, 26c for scraping the dried objects attached to the inner circumference of the rotary drum 1 as the rotary drum 1 rotates. The mainspring that has been further scratched and dropped is dropped from the substantially cylindrical top of the rotary drum 1, and the operation is repeated. Since each of the above-mentioned strips for scraping up dried objects 26a, 26b, 26c is inclined with respect to the axis in the direction of blocking the flow of hot air, the mainspring scraped up by the above-mentioned strips is the hot air discharge side. In addition, the mainsprings that are scraped up by the scraping bar 26 are not scraped at the same time, but a part of them is scraped up and repeatedly dropped. However, the mainspring scraped up to the upper part by the crosspiece does not fall at the same time due to the tilt of the crosspiece. Therefore, the mainspring dropped is scattered and efficiently exposed to hot air.

In the above-described mainspring drying, the mainspring scraped up by the bar 26 for scraping the dried object and dropped is dropped onto the bamboo rack 25 laid on the inner peripheral wall of the rotary drum 1, so the mainspring is bamboo bamboo. The main body is scratched by the bar 26a, for example, at a position where the mainspring scraped up by the bar 26 for scraping the object to be dried falls. If it is raised, the fall position is adjusted so as to fall while being partitioned by the crosspieces 26b and 26c. That is, since the rotating speed of the rotary drum 1 is controlled so that the dried drum always falls into the area defined by the three strips 26a, 26b, and 26c for scraping up the dried object, the mainspring and the like that have fallen are It can be carried out efficiently because it can be scraped up with a dry product scraping bar.

When it is necessary to know the degree of drying during the mainspring drying, it is possible to inspect through the inspection port 32 provided on the end plate 20. When the degree of drying is confirmed and the product is dried, The operation of the motor 8 and the heat exchanger 5 is stopped, the rotation of the rotary drum 1 is stopped, the take-out door 9 is opened, and the dried product mainspring is taken out. By repeating such operations, a large amount of mainsprings can be efficiently processed.

[Effect of device]

 In the mainspring dryer according to the present invention, hot air is supplied from one of the rotary drums into which the mainspring, which is the material to be dried, is supplied, and the hot air is sucked from the other, and bamboo bamboo is laid on the entire inner circumference of the rotary drum. At the same time, the inner circumference of the rotating drum is divided into three equal parts, and the strips for scraping the dried object are tilted with respect to the axis of the rotating drum in the direction of blocking the flow of hot air from the upper surface of the bamboo rack. Since it is fixed, the mainspring scraped up by the crosspiece is securely drawn up without being attracted to the hot air discharge side, and the mainspring scraped up by the crosspiece falls from the approximately cylindrical top of the rotating drum. However, when it falls, it is scattered by the hot air and surely dries.

When the mainspring is dropped, since bamboo sticks are laid on the inner circumference of the rotating body of the present invention, the falling mainspring is buffered by the bamboo sticks and is not damaged. Also, since the rotation speed of the rotating drum is controlled so that the fall position of the wound mainspring falls into the area defined by the three scraping bars for the material to be dried, the drying is performed efficiently. It is something that will be done.
