Description

The invention relates to devices for producing essential oils, including fir.

Known mobile fir plant PPU-1, consisting of a steam generator - boiler KB-100, distillation vat, with fir branches laid inside. The distillation vat is made in the form of a cylindrical sealed container in which an overpressure of 0.6 atmospheres is maintained. For the convenience of loading and unloading, the distillation vat is mounted on hinges and can be rotated in a vertical plane. The hinge shafts are connected to the side surface of the distillation tank, and the hinge body is fixed to the bed. The lid of the tub is retractable, mounted on a trolley moving on a rail. To raise and lower the lid of the vat, screws with handwheels mounted on the trolley are installed above it. To supply steam from the KV-100 boiler to fir branches, there is a steam piping system and a steam cutter located under the fir branches (1).

A disadvantage of the known device is that it is not effective when working in winter conditions, cumbersome. Steam leaks in the steam piping system, and the temperature of the transported steam decreases. The steam cutter does not create uniformity in the supply of steam to the area of fir branches. As a result, the displacement of essential oils by steam from the pores of the green mass of fir branches does not occur evenly. The procedure for sealing the distillation vat with a lid mounted on top is complicated.

The known principle of installing a steam generator inside the apparatus, in which steam leakage in the steam piping system is eliminated. The casing of the device is sealed (2).

The essence of the invention lies in the fact that the steam generator installed inside the sealed container of the distillation tank is made in the form of a liquid atomizer and thermal energy storage device located above the heat energy emitter. The radiator of thermal energy is formed by the inner surface of the lid of the distillation vat and is installed under the vat. Traction nuts that are connected to the screws are fixed on the side surface of the cover, and the screws are fixed on the bed and can be turned by the handwheels.

The drawing shows a fir plant. The fir plant consists of a bed 1. On the bed 1, a distillation vat 2 is installed with fir branches laid inside 3. Distillation vat 2 is made in the form of a cylindrical tank in which overpressure is maintained. For ease of loading and unloading, the distillation vat 2 is mounted on hinges 4 and can be rotated in a vertical plane. The axle shafts 5 of the hinge 4 are connected to the side surface of the distillation tank 2, and the body 6 of the hinge 4 is fixed to the bed 1. Under the distillation tank 2 there is a cover 7. On the side surface of the cover 7 are traction nuts 8 that are connected to the screws 9. Screws 9 mounted on the frame 1 and can be turned by handwheels 10. A heat source 11 is mounted in the bottom of the lid 7. The outer surface of the lid 7 is insulated with heat-insulating material 12, and the inside is equipped with a heat energy emitter 13. Above the heat energy emitter and 13 are mounted fluid spray 14 and heat accumulator 15. At the bottom of the distillation tank 2 mounted parootvodnoy port 16.

Firing installation works as follows. The distillation vat 2 is filled with fir branches 3. When the inner space of the vat 2 is full, it is turned upside down on hinges 4. Then the lid 7 is advanced towards the tank 2, turning the screw 9 with the handwheel 10. The tank 2 is hermetically sealed with the cover 7. Then, water is sprayed to the liquid atomizer 14, which is sprayed over the radiator 13. Under the action of heat energy, the water droplets turn into steam. Passing through the thermal energy storage 15, the steam heats up even more, turning into superheated steam. The pressure in the distillation tank 2 rises and reaches the worker, in which there is an intensive process of steam passing through the spores of fir branches 3 and saturating it with essential oils. The resulting vapor-gas mixture is displaced from the tank 2 through the branch pipe 16 into the refrigerator and condenses. After the expulsion of the vapor-gas mixture from the tank 2, the lid 7 is pulled out, the tank 2 on hinges 4 is rotated 90 ° in a vertical plane. Spent fir branches 3 are removed from the tub 2.

The reconstruction of the PPU-1 firmaking plant makes it possible to alleviate the working conditions of workers and reduce labor intensity during work in winter conditions.
