Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a smoking method and apparatus for using pine resin in a smoking oven for smoking.

To explain the present invention in detail with reference to the drawings, four or six dry distillation tanks 3 made of heat-resistant metal are attached to the upper part of the fire opening 2 at the bottom of the smoker kiln 1, depending on the size of the kiln, and exhaust holes 5 are installed. A gas pipe 4 with a hole opened is connected and attached to the dry distillation tank 3 so that the exhaust hole 5 faces downward, and the gas generated from the dry distillation tank 3 is placed so as to flow into the exhaust hole 5.

A heating tank 15 is installed near the kiln, a lid 21 with a hole in the center is prepared, a circular rope part 19 is inserted into the hole 22,
Place the rosin in the hanging rope part 19 on a medium weighing scale. Install the electric pump 17, pipe the oil pipe IO from the heating tank 15 to the dry distillation tank 3 so that the electric pump 17 can supply oil, and connect the return oil pipe 20 from the middle of the oil pipe IO to the upper center of the heating tank 15. The oil outlet should be directed downwards, and the oil should be installed so that it is discharged directly below the inside of 161!19. A return oil valve 23 is installed near the parting point of the return oil pipe 20. An oil stop valve 14 is installed closer to the kiln than the oil pipe lOO branching point, and a pressure adjustment valve 13 is installed beyond that.
Attach a pressure gauge 12 near the kiln. A thermometer 18 is attached to the lower part of the heating tank 15 so that the heating temperature can be checked.A steam pipe 16 for sending steam from the boiler for heating is attached in a spiral shape, and a stop valve 20 is attached to enable heating. Leave it there.

First, when the kiln is about to finish firing, pour kerosene or heavy oil from the opening of the rope part 19 into the kiln.
07χ~307, open the steam valve 20, send high-temperature steam through the steam pipe 16, heat it while watching the thermometer 18, and when the temperature reaches around 50°C, pour 1 pine resin into the rope part 19.
0kg = put around 15kg, oil stop valve 14
Close the door and start the electric pump. Kerosene or heavy oil is sucked up from the lower part of the heating tank 15, passes through the oil pipe IO, returns to the oil pipe 20, and flows down vigorously onto the pine resin in the will 19. The heated pine resin gradually begins to dissolve and become sticky. It becomes a strong liquid and passes through the mesh together with kerosene or heavy oil, mixes with kerosene or A heavy oil, enters the heating tank 15, is sucked up again from the heating tank 15 by the electric pump 17, and is discharged into the rope section 19. Since the mixture is stirred by repeating the circulation, a smooth mixed oil with less stickiness can be created. If the time is right for fumigation, the oil pipe l
Open the oil stop valve 14 of O, gradually open the pressure regulating valve 13 while watching the pressure gauge 12, and feed the mixed oil into the dry distillation tube 3. The mixed oil that entered the dry distillation tube 3 becomes a hydrocarbon gas that vaporizes in the dry distillation tube 3, passes through the gas pipe 4, is discharged from the discharge hole 5, diffuses, and comes into contact with the fired product and thermally decomposes, producing a silver-colored A film is applied and fumigation is performed. Heating tank! When the temperature in Step 5 reaches 80°C to 90°C, the pine resin is completely liquefied, and when mixed with kerosene or heavy oil, it loses its stickiness and becomes a smooth oil. Since kerosene or A-heavy oil and pine resin have different specific gravities, the circulation is continued without stopping the return oil valve 23 until the smoking is completed, and the smoking is continued while stirring. As the smoking progresses, open the pressure regulating valve 13 to increase the amount of oil, and after smoking for 1 hour to 1 hour and 30 minutes, stop the electric pump 17 to finish smoking, and close the incubation hole of the kiln to seal it. Finish the fumigation work.

Since ancient times, pine resin containing a lot of pine resin has been used as the best material for smoking roof tiles. Using cedar wood or miscellaneous wood would result in tiles with a lackluster finish, so although they were used for burning, they were not used for smoking.

In recent years, smoking kilns have also been designed to burn LP gas and oil, and since LP gas and oil are used for smoking, the kilns have been designed so that they cannot use pine resin. If today's kilns were designed to be filled with pine resin, they would be larger and more expensive, and the work would require a lot of labor, making them unsuitable for practical use. If only pine resin were to be used for smoking, the method would be to heat it to a liquid state and pour it into the kiln, but it would turn into a mushy liquid, but it is very sticky and even if you send it with an electric pump, the oil pipe would be clogged. Not distributed. Even if you force the kiln through once, the remaining oil in the oil pipe and electric pump will cool and solidify by the time you fire the next kiln, making it unusable. Also, liquid mixed oils made by processing pine resin with other oils are commercially available, but mixed oils containing a large amount of pine resin are highly sticky and cannot be heated through small oil pipes, making it difficult to distribute. Especially in winter, oil tends to solidify.

In the present invention, solid pine resin or powdered pine resin is mixed with kerosene or heavy oil, heated, turned into a smooth oil, and can be easily smoked using a small oil pipe or device. By heating even sticky oil with a high rosin content,
It becomes a smooth oil. Also, the temperature during smoking in the kiln is
900℃～l.

Smoking is carried out at a high temperature of 1,000 degrees Celsius, so if cold oil is sent into the kiln, the fired product will spall, resulting in defective products, but if hot oil is sent into the kiln, spalling will not occur.

The purpose of the present invention is to heat solid/powdered pine resin and highly sticky pine resin mixed oil with kerosene or heavy oil to improve distribution and simplify the work, thereby producing a glossy fumed product. It is to obtain.
