Description

Technical Field

[0001] The invention relates to the field of tea processing, in particular to a hot air furnace. Background Art

[0002] Tea, as one of the most popular drinks in the world, has a long history and rich cultural connotations. Tea originated in China. For thousands of years, its planting, production and drinking methods have been constantly evolving and developing. From the initial medicinal use to later becoming a drink in daily life, tea has gradually integrated into people's lives. There are many types of tea, the most common ones are green tea, black tea, oolong tea, white tea, black tea, etc.; Green tea; such as Longjing and Biluochun, are not fermented, retaining the natural color and nutrients of tea, and have a fresh and refreshing taste; Black tea; such as Keemun black tea and Zhengshan Xiaozhong, after complete fermentation, the soup color is bright red and the taste is mellow, Oolong tea; such as Tieguanyin and Dahongpao, the semi-fermentation process makes it have both the fragrance of green tea and the mellowness of black tea, White tea; represented by Baihao Yinzhen, is simple to process and has a cool tea nature, Black tea; such as Pu'er, after a long period of pile fermentation, it has a unique aged fragrance and Health benefits: The quality of tea depends on many factors, including the variety of tea trees, the growing environment, the picking time and the production process. High-quality tea usually comes from high-altitude, pollution-free tea gardens. The tea is picked freshly and evenly, and the production process is even more critical. From withering, rolling to baking, every link requires careful control by experienced craftsmen to ensure that the color, aroma, taste and shape of the tea are in the best state. Drinking tea is not only a taste enjoyment, but also beneficial to health. Tea is rich in tea polyphenols, caffeine, vitamins and other nutrients, and has multiple functions such as anti-oxidation, refreshing the mind, lowering blood lipids and losing weight, and preventing cardiovascular diseases. Different teas have slightly different health effects.

[0003] In short, tea, as a gift from nature, has become an indispensable part of people's lives with its rich varieties, unique flavor and numerous benefits, conveying warmth and beauty. The tea making process is extremely delicate. The basic production process includes: withering → spreading → shaking → making green tea → killing green tea → rolling → drying → raw tea and other processes. However, the hot air furnace used for making green tea is a device that heats the incoming cold air into hot air and outputs it through a heating device. In the process of frying tea, the hot air in the hot air furnace needs to be used to dry or shake the tea leaves, thereby increasing the quality of the tea. Tea is a kind of plant leaves that can be brewed with boiling water, making the tasteless boiled water have a fresh fragrance. After tea became known to people, more and more teas appeared, and drinking tea became something that Chinese people were keen on. However, tea leaves need to be processed before drinking so that they can become dry and can be brewed with boiling water. Therefore, electric hot air furnaces are needed to process tea leaves. Hot air furnaces are mainly used to generate high-temperature hot air for heating purposes, including drying tea leaves and Chinese herbal medicines, withering tea leaves, etc. There are many steps in tea processing. The hot air furnace is connected to the withering machine to wither and dry the tea leaves. The hot air furnace generally adds heat to the furnace through a heating device. The residual heat inside the hot air furnace after processing is wasted, and the utilization rate of the factory's thermal energy is low.

[0004] Therefore, it is necessary to provide a hot blast stove to solve the above technical problems. Summary of the invention

[0026] A temperature indicator 6 is fixedly mounted on the other side of the surface of the smoke exhaust fan 4 .

[0027] Hot air furnace startup operation 1. Turn on the power and check whether the power supply is normal; 2. Check whether the high temperature fan and induced draft fan are rotating in the forward direction; 3. Open the furnace door 8 and put some selected particles into the furnace, and ignite them with fuel; 4. After ignition, turn on the smoke generator 4 and the pellet machine 3 at the same time. It is recommended to set it at gear 6-7. When the temperature indicator 6 shows that the temperature reaches 180°C-240°C, the main fan 5 is started immediately.

[0028] The wind force of the main fan 5 should be adjusted according to the moisture content and output of the tea leaves, and the temperature is also adjusted by adding or subtracting the speed regulator 7 of the pellet machine. In normal use, the heat recovered after two hours may increase. Here, pay attention to the changes in the temperature indicator 6. If the temperature is too high, please lower the gear of the pellet machine speed regulator 7. If the tea leaves are too dry, it means that the air volume is too large. It is recommended that under normal circumstances, the inverter be adjusted to 400 Hz to keep the pellet burner pipeline unobstructed and prevent blockage.

[0029] Hot air furnace shutdown operation 1. Turn off the pellet burner and wait for the furnace to cool completely; 2. After cooling, turn off the smoke exhaust fan and main fan, and turn off the power supply; 3.

[0031] When the main furnace 1 is closed for use, the heat is transferred to the withering machine through the exhaust pipe 11 to achieve heat circulation.

[0032] The main furnace 1 burns pellets, and an inner tank is arranged inside the main furnace 1, which can provide thermal efficiency and the temperature can reach 800 degrees. The main furnace 1 is connected to the fixing machine through the air inlet pipe 12 and the exhaust pipe 11. The fixing machine is provided with a dehumidifying device. The dehumidifier draws away the moisture through the pipeline, and then the hot air in the moisture is discharged into the interior of the auxiliary compartment 2 through the air inlet pipe 12. The auxiliary compartment 2 then blows the hot air into the main furnace 1, and the heat inside the main furnace 1 is transmitted to the fixing machine through the exhaust pipe 11, thereby realizing efficient utilization of the heat cycle.

[0033] Compared with the related art, the hot blast stove provided by the present invention has the following beneficial effects: The present invention provides a hot blast furnace, which introduces the heat discharged from the fixing machine into the interior of the main furnace 1 through the air inlet pipe 12, and guides the residual heat in the main furnace 1 into the fixing machine through the exhaust pipe 11, thereby realizing heat circulation. The auxiliary compartment 2, the feeding fan 9 and the combustion-supporting fan 10 supply heat to the main furnace 1, thereby improving the heating effect of the hot blast furnace, realizing efficient utilization of the heat cycle, and improving the practicability of the device.

The support plate 143 is in contact with the surface of the bottom of the auxiliary compartment 2, and the second universal wheel 144 moves upward with the support plate 143. The second universal wheel 144 no longer contacts the ground, so that the supporting feet at the bottom of the auxiliary compartment 2 support the ground. When the support plate 143 moves, it drives the connecting plate 131 to move, and the connecting plate 131 drives the connecting ring block 132 and the first universal wheel 133 to move together.

[0045] Compared with the related art, the hot blast stove provided by the present invention has the following beneficial effects: The present invention provides a hot blast furnace, which controls the output shaft of the hydraulic cylinder 142 to move downward through an external power supply, pushing the support plate 143 to move downward, and the support plate 143 drives the second universal wheel 144 to move downward and support the ground, and the support plate 143 drives the auxiliary device 13 to move downward together, so that the first universal wheel 133 at the bottom of the connecting ring block 132 supports the ground, and the main furnace 1 and the auxiliary compartment 2 are suspended in the air, and the user can push the hot blast furnace to move and transport through the universal wheel.
