Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressed flower drying device for drying plants such as flowers, leaves and stems at high speed.

[0002]

2. Description of the Related Art In a conventional pressed flower drying method, a plant is sandwiched between a large number of laminated dry sheets enclosing a desiccant and pressure is applied from above and below, and the plant is placed in a drying chamber and dried while being heated if necessary. It was

[0003]

In the conventional pressed flower drying method, since a plant is sandwiched between dry sheets and a large number of them are piled up and put together in a drying chamber while applying pressure,
The drying process took time and effort. The problem to be solved by the present invention is to solve these problems of the conventional pressed flower drying method and to provide a pressed flower drying apparatus capable of performing the drying process simultaneously and continuously.

[0004]

Means for Solving the Problems The gist of the present invention which has solved the above problems is as follows: 1) A heat source for heating a drum surface is arranged inside a rotary drum, and a plant is sandwiched and conveyed on the outer peripheral surface of the rotary drum. A pressed flower drying device characterized in that the pressed flower carrier having water absorption is sent in close contact. 2) The heat source is a plurality of electric heaters so that the inner surface of the contact part of the pressed flower carrier of the rotating drum is irradiated. The pressed flower drying device according to the above 1), wherein the fan is provided outside the rotary drum, the fan being provided in the rotary drum so as to be separated by a predetermined distance and blowing air toward the surface of the contact portion of the pressed flower carrier.

[0005]

According to the present invention, a plant such as a flower stalk is sandwiched between water-absorbing belt / sheet-shaped pressed flower carriers and is sent to a rotary drum, and the rotary drum rotates in close contact with the outer peripheral surface of the rotary drum. Since there is a heat source inside, the surface of the rotating drum is heated, and the pressed flower carrier that is in close contact with it is also heated, and the moisture and humidity of the pressed flower are strongly absorbed by the heated pressed flower carrier, and are vaporized by the heat. Evaporate. In this way, the water of the plant is strongly absorbed, rotates with the rotating drum while vaporizing and evaporating, and the pressed flowers are strongly and quickly dried.
In particular, in the case where a fan is installed outside the rotating drum to blow air toward the pressed flower carrier, the pressed flower carrier is kept water by blowing away the steam, moisture, and water generated from the surface of the pressed flower carrier with air.・ Prevents a decrease in water absorption and drying power due to high humidity, and increases the water absorption and drying power of the pressed flower carrier. When the pressed flower carrier is sent together with the rotary drum, they are separated and the next processing is performed.

Embodiments of the present invention will be described below with reference to the drawings. In the present embodiment, as the pressed flower carrier, a color endless belt impregnated with a color holding agent for fixing and maintaining the color of the pressed flower or a color treatment agent such as a fresh colorant for discoloring or vibrating the color, and water absorption and moisture absorption A long dry endless belt is stacked and the plant is sandwiched between the endless belts. Further, a color retention agent is used as a color treatment agent, and a dry endless belt is used which is impregnated with anhydrous magnesium sulfate and then dried. Further, as a heat source, six electric heaters having a wavy reflecting surface on the rear side are arranged in the rotary drum. Two fans are provided on the outside of the rotary drum to blow air to the pressed flower carrier portion which is in close contact with the rotary drum. 1 is an explanatory view of the embodiment, and FIG. 2 is a sectional view taken along the line AA of FIG.

In the figure, 1 is a rotary drum having a diameter of about 80 cm,
Reference numeral 2 is an electric heater for heating the surface of the rotary drum 1, 3 is a rotary drive shaft of the rotary drum 1, 4 is a dry endless belt made of cloth impregnated with anhydrous magnesium sulfate and is in a dry state, 5
Is an endless belt for color of cloth or non-woven fabric impregnated with a color-retaining agent such as anthocyan, 6 is a pressed flower, 7 is a pressed flower placement carrying-in surface on which a pressed flower 6 (undried plant) of the dry endless belt 4 is placed, 8 The discharge surface of the pressed flower 6 of the color endless belt 5, and 9 is the rotary drum 1.
A fan that blows air toward the fan to disperse vapor and vaporized components to improve drying efficiency, 10 is a color holding liquid tank that stores a color holding agent such as anthocyan, 11 is a guide roller, and 12 is a pressed flower carrier.

In this embodiment, as the dry endless belt 4 of the pressed flower carrier 12, a belt made of cloth and impregnated with anhydrous magnesium sulfate solution and dried is used. The pre-dried / pressurized pressed flowers 6 or the collected plant bodies are manually placed on the pressed-flower loading / carrying-in surface 7 of the dry endless belt 4.
The pressed flower 6 is wound on the rotary drum 1 while being dried little by little. In the rotary drum 1, the pressed flower 6 is sandwiched between the color endless belt 5 and the dry endless belt 4 (see FIG. 2) to form the pressed flower carrier 12 and is wound around the rotary drum 1 to be attached to the outer peripheral surface of the rotary drum. It comes into close contact and is sent as the rotary drum 1 rotates. The color retaining agent of the endless color belt 5 of the pressed flower carrier 12 holds and maintains the color so that the pressed flower 6 does not touch the pressed flower 6 and discolor or fade. At the same time, the pressed flowers 6 are rapidly dried due to heat from the rotary drum 1 and absorption of water and moisture by the anhydrous magnesium sulfate cloth of the dry endless belt 4 of the pressed flower carrier 12 on the outer periphery. Further, the fan 9 blows off the moisture, steam, and moisture on the surface of the pressed flower carrier 12 with air to enhance the water absorbing power and the drying power.

With this rotary drum 1, pressed flower carrier 12
Is heated and dried for several tens of seconds to several hundreds of seconds, the pressed flower 6 is placed on the color endless belt 5 and sent out, and is discharged from the carry-out surface 8. The color endless belt 5 is dipped in the color retaining liquid tank 10 to be impregnated with the color retaining agent. In this embodiment, the color retention and the drying process can be performed simultaneously and continuously in several tens to several hundreds of seconds.

[0010]

As described above, according to the present invention, the drying treatment can be continuously carried out, and the work of drying pressed flowers can be made extremely efficient.
