JPH0678734A - Method for drying flowering fern - Google Patents

Abstract

PURPOSE:To efficiently dry flowering fern. CONSTITUTION:A beam crosspiece 1 is laid in a rotary barrel 11 made of steel plate, flowering fern 12 is raised up to the top by the crosspiece and dropped. On the other hand, hot air from a heat exchanger 4 is supplied from a side wall at the one-side of the rotary barrel 1 and exhausted from a side wall at the other side. The flowering fern in the rotary barrel is rubbed and dried. Since the flowering fern is effectively dried with hot air controlled at a given temperature by the operation, the product is improved.

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mainspring dryer.

2. Description of the Related Art Japanese Patent Application No. 57-49

[0002]

In the devices described in the prior art, firewood is used as a heat source for drying the mainspring. Therefore, it was necessary to constantly replenish firewood and control the temperature, which was a labor-intensive task. It is practically impossible to always keep the temperature at the specified temperature because the temperature is controlled by firewood. Further, since the rotary drum is composed of a perforated plate, there is a drawback that fine powder is scattered outside the drum and drops onto the bonfire. Furthermore, since there is a bonfire at the bottom of the rotating body when taking out the product, it has to be avoided and it is inconvenient to handle. The conventional technique has the above-mentioned problems, and the present invention has been made in view of such problems of the conventional technique. The purpose thereof is to reduce the labor of the drying operation. By controlling the drying temperature to a predetermined temperature, it is an object of the present invention to provide an apparatus capable of manufacturing higher quality products.

[0003]

In order to achieve the above-mentioned object, the mainspring dryer according to the present invention has an outer periphery made of an iron plate and is provided inside a cylindrical rotary cylinder having a door provided at a part of the outer periphery. A single or a plurality of crosspieces are provided, and a heat exchanger having a temperature adjusting function provided near the rotary drum supplies hot air from one side wall opening of the rotary drum and discharges it from the other side wall opening of the rotary drum. It is characterized in that a speed change device for changing the speed is provided.

[0004]

The mainspring stored in the rotating drum is scraped up by the crosspiece as the rotating drum rotates, and falls to the lower portion at the central side of the upper portion. This operation is repeated while the rotary cylinder rotates. As a result, the mainspring is kneaded, the cotton is removed, the mainspring is dried by the hot air from the side wall of the rotary drum, and the cotton is discharged from the hot air outlet.

EXAMPLES Examples will be described with reference to the drawings. FIG. 1 shows a schematic front view of a mainspring dryer in the case of a method of sucking hot air from the heat exchanger 4 with a fan 6. Figure 2
Shows a schematic front view of a mainspring dryer in the case of a method in which a fan for pushing hot air is attached to the heat exchanger 4 and hot air is pushed into the rotary drum 1. In this case, the fan is unnecessary. The mainspring 12 is charged into the rotary drum 1 from the mainspring charging chute 3, and is lifted up to the upper portion by the crosspiece 11 in the rotary drum 1 and falls. While the rotary drum 1 is rotating, this operation is repeated and the mainspring is twisted and the cotton 13 is removed. On the other hand, the hot air from the heat exchanger 4 is supplied into the rotary drum 1 and discharged. At this time, the mainspring 12 is dried, and the cotton 13 is discharged to the outside of the rotary drum 1 together with the exhaust of hot air. The hot air is controlled to a predetermined temperature by a temperature controller (not shown). Further, the dried product can be easily taken out of the rotary drum 1 by opening the mainspring take-out door 2.

[0006]

Since the present invention is constructed as described above, there is an effect that the labor can be saved and hot air of a predetermined temperature can be supplied by the temperature controller, so that the quality can be improved.
