A kind of agarwood tea scenting device

Abstract

The invention discloses an agarwood tea scenting device, which is composed of an aroma generating mechanism, a rectifying mechanism, a scenting mechanism and a scenting temperature control mechanism; the working principle is as follows: the agarwood in a heating tank is heated by a heating coil to evaporate volatile oil and mixed vapors of linalool, linalool and the like; after the mixed vapor enters a rectifier, the volatile oil vapor is condensed by a solution on a tower plate of the rectifier; the heat released during condensation causes part of the solution on the tower plate to evaporate, thereby increasing the vapor mass fraction of effective components; therefore, during the rising process of the mixed vapor, the volatile oil is continuously condensed, and the mass fraction of linalool and linalool vapor is continuously increased; after entering a local condenser, since the condensation medium is a heat transfer oil at 320-350°C, the vapor above 350°C is completely condensed, while the vapors of linalool and linalool, the effective components with a boiling point below 320°C, enter the interior of the aroma absorbing tank and are absorbed by tea balls at a low temperature, thereby completing the scenting process of the agarwood.

Description

Technical Field

[0001] The invention relates to the technical field of agarwood tea scenting, and in particular to an agarwood tea scenting device. Background Art

[0002] Agarwood is a precious spice and has been listed as the top of all fragrances since ancient times. Agarwood is a rare antibacterial and immune-enhancing medicinal material in nature. It has a fragrant smell and enters the lungs, kidneys, spleen, stomach, and meridians. It is the best medicinal material among qi-moving medicines. It can regulate the flow of qi in the human body and dredge the functions of internal organs. It is a very effective medicinal material for the lungs, kidneys, liver, stomach, intestines, heart, etc. The aroma of tea scented with agarwood enters the spleen, clears the mind and regulates qi, nourishes the five internal organs, relieves cough and resolves phlegm, warms the stomach and spleen, and relieves pain. It is a top-notch drink.

[0003] Traditional agarwood tea is made by heating agarwood to release its aroma, and then scenting the tea leaves to obtain agarwood tea. The quality of the agarwood leaf tea prepared is poor for the following reasons: (1) In addition to the active ingredients linalool and linalool, agarwood also contains volatile oils, especially a large amount of genkwain. Genkwain is a highly irritating substance and is currently used as a chemical product. Because the traditional method of scenting agarwood tea cannot remove the volatile oils in the agarwood leaves, the tea tastes poor and is spicy and irritating. (2) The two main components of agarwood, linalool and linalool, have boiling points of 198°C and 311°C, respectively. They are easily condensed on the surface of the scenting jar during the scenting process, and very few active ingredients can actually be absorbed by the tea leaves, wasting agarwood resources. Summary of the invention

[0004] The purpose of the present invention is to provide an agarwood tea scenting device that can distill volatile oil while allowing linalool and linalool to be completely absorbed by tea leaves, by utilizing the temperature difference between the boiling points of genkwain and the effective ingredients of agarwood.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

The oil end is communicated with the cooling end inlet of the local condenser (5), and the cooling section outlet of the local condenser (5) is communicated with the other side of the bottom end of the temperature control tank (1), forming a heat transfer oil circulation circuit. A temperature sensor (13) is provided on the outside of the aroma absorption tank (3), and the temperature sensor (13) is placed in the heat transfer oil (2) inside the temperature control tank (1). The temperature sensor (13) is connected to the circuit of the heater (15), forming a heat transfer oil heating device. The heat transfer oil circulation circuit and the heat transfer oil heating device constitute the temperature control mechanism of the device.

[0007] Preferably, the places where the heating tank (17), the rectifier (7), the local condenser (5), and the aroma absorption tank (3) are connected are all sealed and welded to form an integrated structure, and the interior is vacuum; the heating tank (17) is provided with a process valve, and the process valve is connected to a vacuum pump to form a vacuum extraction device.

[0013] Compared with the prior art, the present invention has the following significant effects:

[0014] (1) From the above technical solution, it can be seen that

[0015] During the high-temperature heating process, agarwood releases mixed vapor of volatile oil and effective ingredients such as linalool and linalool. After the mixed vapor is distilled by the distillation mechanism, the volatile oil is condensed into liquid, and the effective ingredients such as linalool and linalool enter the aroma absorption tank and are absorbed by the tea leaves. Therefore, the tea leaves no longer contain volatile oil but contain a large amount of linalool and linalool, which improves the taste and quality of the tea leaves.

[0016] (2) The present invention provides a temperature control mechanism on the outside of the aroma absorption can, so that the temperature of the surface of the aroma absorption can is kept at 320-350°C, thereby preventing linalool and linalool from being condensed on the surface, so that the effective ingredients are completely absorbed by the tea leaves.

[0017] (3) The present invention provides an anti-radiation coating on the inner side of the aroma absorption can, and the interior of the aroma absorption can is in a vacuum state, so that the tea leaves are in an insulated and low-temperature state, which is conducive to the tea leaves to better absorb the effective substances and also shortens the absorption time.

The device consists of an aroma generating mechanism, a distillation mechanism, a scenting mechanism and a scenting temperature control mechanism; a heating coil 10 is provided at the bottom of the heating tank 17, and agarwood 9 is placed on the heating coil 10, constituting the aroma generating mechanism of the device; a gas opening is provided at the top of the heating tank 17, and the gas opening is communicated with the bottom of the rectifier 7, and the top of the rectifier 7 is communicated with the bottom of the local condenser 5, constituting the distillation mechanism of the device; the top of the local condenser 5 is communicated with the bottom of the fragrance absorption tank 3, and a hanging line 11 is provided at the top of the fragrance absorption tank 3. A tea ball 12 is suspended on a suspension line 11, constituting a scenting mechanism of the device; a temperature control tank 1 is provided outside the scent absorbing tank 3, and heat transfer oil 2 is filled inside the temperature control tank 1, and the temperature of the heat transfer oil 2 is controlled to be 320-350°C; one side of the bottom end of the temperature control tank 1 is communicated with the top oil inlet end of the heat transfer oil tank 14, and the outlet end of the bottom of the heat transfer oil tank 14 is communicated with the oil inlet end of the heat transfer oil pump 16, and the oil outlet end of the heat transfer oil pump 16 is communicated with the cooling end inlet of the local condenser 5, and the cooling section outlet of the local condenser 5 is communicated with the other side of the bottom end of the temperature control tank 1, constituting a heat transfer oil circulation circuit; a temperature sensor 13 is provided outside the scent absorbing tank 3, and the temperature sensor 13 is placed in the heat transfer oil 2 inside the temperature control tank 1, and the temperature sensor 13 is connected to the circuit of the heater 15, constituting a heat transfer oil heating device, and the heat transfer oil circulation circuit and the heat transfer oil heating device constitute the scenting temperature control mechanism of the device.

[0021] Its working principle is as follows: the agarwood 9 in the heating tank 17 is heated by the heating coil 10, evaporating volatile oil and mixed vapors such as linalool and linalool. After the mixed vapor enters the rectifier 7, the volatile oil vapor is condensed by the solution on the tower plate of the rectifier 7. The heat released during condensation causes part of the solution on the tower plate to evaporate, thereby increasing the vapor mass fraction of the effective ingredient. Therefore, during the rising process of the mixed vapor, the volatile oil is continuously condensed, and the mass fraction of linalool and linalool vapor is continuously increased. After entering the local condenser 5, since the condensing medium is a heat transfer oil at 320-350°C, the vapor above 350°C is completely condensed, and the vapor of the effective ingredients linalool and linalool with a boiling point below 320°C enters the interior of the fragrance absorption tank 3 and is absorbed by the tea ball 12 with a low temperature, completing the scenting process of agarwood.

[0022] In order to avoid wasting the effective ingredients of agarwood, a temperature control tank 1 is provided outside the fragrance absorption tank 3. The temperature control tank 1 is filled with heat transfer oil 2. The temperature of the heat transfer oil 2 is controlled to be 320-350°C, so that the temperature of the surface of the fragrance absorption tank 3 is at 320-350°C, preventing agarwood alcohol and agarwood spirol from being condensed on the surface, so that the effective ingredients are completely absorbed by the tea leaves. The temperature sensor 13 transmits the real-time temperature signal of the surface of the fragrance absorption tank 3 to the heater 15. When the temperature of the heat transfer oil 2 decreases, the heater 15 is turned on to heat the heat transfer oil. The heat transfer oil with increased temperature first enters the local condenser 5 to condense the volatile oil, takes away the condensation heat, and then enters the temperature control tank 1, so that the heat transfer oil in the temperature control tank 1 is always at a temperature between 320-350°C.
