Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an apparatus for dry-distilling various crude drug raw materials to produce a chemical solution.

[0002]

[Prior Art]

 Conventionally, there has been a method of producing a drug solution by dry distillation of crude drug raw materials. In this method, Japanese paper and other materials are drummed on top of donburi, and crude drug ingredients are piled up.A charcoal fire or the like is placed on the top of the crude ingredient to gradually smoke the crude drug ingredients. However, the chemical solution was condensed through the Washi paper into the donburi and was collected.

However, such a method has a small scale and is inefficient because it is carried out by using existing equipment, and since it is heated by using a charcoal fire, the quality of the product is not stable and the yield is also high. There were few.

[Problems to be solved by the device]

 According to the present invention, when a crude drug raw material is dry-distilled based on the traditional technique as described above to produce a chemical liquid, a large amount of the crude drug raw material is effectively heat-treated to efficiently recover a stable quality liquid chemical. It is an object of the present invention to provide an improved carbonization device capable of performing the above.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the herbicide distillation device of the present invention comprises a cooling tank having an inlet and an outlet of cooling water, and a cradle that holds an interval along which the cooling water can flow along the inner wall of the cooling tank. A container for condensing liquid medicine, and a cylindrical body with a lower end formed in a shape to fit the upper end of the container for condensing liquid, an electric heater provided on the inner surface, and an inorganic filter plate detachably provided on the bottom The raw material heating container and the lid having an outer diameter smaller than the inner diameter of the raw material heating container and provided with an electric heater on the lower surface are sequentially stacked.

Further, by providing a connecting member for fixing the chemical liquid condensing container to the cooling tank, it is possible to ensure that the chemical liquid condensing container does not become unstable even if buoyancy acts on the chemical liquid condensing container in the cooling tank containing water. The carbonization device can be assembled. Furthermore, by configuring the upper edge of the body of the chemical liquid condensing container and the lower edge of the body of the raw material heating container via a heat insulating packing, the thermal efficiency and the condensation efficiency can be further enhanced.

If a chemical liquid outlet plug is provided at the bottom of the chemical liquid condensing container, the operation of taking out the chemical liquid condensed in the container becomes extremely easy. In the device of the present invention, the inorganic filter plate provided at the bottom of the raw material heating container has a fine mesh so that the raw material placed on it does not fall out, and the smoke generated by carbonization can pass freely, and the heat resistance is high. It is desirable that the material has a property, and for example, a woven cloth made of glass fiber is suitably used.

[Action]

 In the crude distillation device of the present invention, first, a cooling tank is installed, cooling water supply and drainage pipes are connected, and a chemical liquid condensing container is installed therein. Next, the container for condensing the liquid chemical is fixed to the cooling tank using the connecting member. After that, a heat insulating packing is attached to the upper edge of the body of the chemical liquid condensing container, and a raw material heating container with an inorganic filter plate attached to the bottom is connected to it. The raw material heating container is filled with crude drug raw material, the lid is placed on it, and while supplying cooling water to the cooling tank, an electric current is passed through the electric heater of the raw material heating container and the electric heater of the lid to supply the crude drug. When the raw material is heated, the crude drug raw material is in a steamed state, and volatile components are generated and pass through the filter plate with smoke, enter the container for condensing the liquid medicine, and are condensed on the inner wall surface.

【Example】

 An example of the crude distillation device of the present invention will be described with reference to FIG. In the figure, reference numeral 1 is a cooling tank, which is provided with a cooling water inlet port 2 and a cooling water outlet port 3 on its side wall and bottom portion so that the cooling water 4 filled in the cooling tank 1 can be replaced. Is becoming In the cooling tank 1, an enameled chemical liquid condensing container 6 is placed on a pedestal 7 and is fixedly connected by a hook-shaped connecting member 5. The cradle 7 is provided with a cooling water flow hole 7a so that not only the side wall but also the bottom surface of the chemical liquid condensing container 6 can be sufficiently cooled. Further, a stopper 6b for withdrawing the condensed chemical liquid 8 is provided at the bottom of the chemical liquid condensing container 6.

The upper end portion 6 a of the chemical liquid condensing container 6 is enlarged so that a heat insulating packing 9 can be attached thereto, and further, the bottom portion of the cylindrical raw material heating container 10 can be fitted through the packing 9. It is like this. A claw 10a is projected on the inner side of the bottom of the raw material heating container 10 so as to receive the wire mesh plate 11 and the glass fiber woven cloth 12 which are fitted together. A heating zone 10b incorporating an electric heater is attached to the inner surface of the side wall of the raw material heating container 10. Reference numeral 13 denotes a lid body having an electric heater incorporated therein, which is placed on the crude drug raw material 14 filled in the raw material heating container 10.

In the carbonization apparatus configured as described above, when the crude drug raw material 14 is filled and then the cooling water 4 is caused to flow in the cooling tank 1 and each electric heater is energized to heat the crude drug raw material 14, Smoke 14 in a steamed state passes through the glass fiber woven cloth 12 and is cooled on the inner surface of the chemical liquid condensing container 6, and the chemical liquid 8 is condensed and accumulated at the bottom. After the crude drug raw material 14 is carbonized in this way, the electric heater is de-energized and allowed to cool, the apparatus is disassembled and the chemical liquid 8 collected in the chemical liquid condensing container 6 is recovered.
