At the same time, the aroma equipment used still has certain defects in moisture and ash removal, temperature detection, etc. Therefore, it is necessary to solve this problem. Summary of the invention
[0003] The purpose of the present invention is to provide a method for improving the aroma of tea leaves, which can be used to solve the above technical problems.

DETAILED DESCRIPTION
[0025] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described in conjunction with the following embodiments. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention. As used herein, the terms "parallel" and "perpendicular" are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors.
[0026] The present invention also provides a tea aroma enhancement method, which specifically comprises the following steps: analyzing the material properties of tea raw materials, determining parameter standards for aroma enhancement treatment of the tea raw materials, starting an automatic aroma enhancement system and setting the operating parameters of the automatic aroma enhancement system, preheating an aroma enhancement machine 20 and adding tea raw materials into a feeding hopper 11, and after the aroma enhancement machine 20 is preheated, starting a material separation unit 10 to automatically perform quantitative material separation on the tea raw materials and adding materials into each aroma enhancement machine 20 according to the determined parameter standards, the aroma enhancement machine 20 operates according to the determined parameter standards to complete the aroma enhancement treatment of the tea, and the tea leaves after the aroma enhancement treatment are collected and sorted into tea leaves of different specifications and qualities by a post-processing unit 30.
[0027] The detailed operation is as follows: the parameter standards include the amount of tea added during aroma treatment, aroma temperature, aroma time, and drum speed; the material properties include the size of the tea leaves, the freshness of the tea leaves, and the moisture content of the tea leaves. The A material transfer conveyor belt 12 is started to take the tea raw materials in the hopper 11, and the material dividing conveyor belt 13 receives the tea raw materials transported by the A material transfer conveyor belt 12 and measures the received amount. When the received amount reaches the parameter standard, the A material transfer conveyor belt 12 stops taking the tea raw materials from the hopper 11, and the material dividing conveyor belt 13 runs to deliver the parameter standard amount of tea raw materials accumulated on it to the unloaded tea box machine for aroma treatment. After the tea raw materials on the material dividing conveyor belt 13 are completely unloaded, the A material transfer conveyor belt 12 is started again to take the tea raw materials, and this is repeated.
[0028] The tea raw materials are measured by installing the material distribution conveyor belt 13 on the material distribution bracket, installing the material distribution bracket on the material rack and installing the weighing sensor 14 on the mounting foot of the material distribution bracket. A dehumidification component A is installed at the tail end of the drum to remove moisture and dust generated during the aroma treatment inside the drum, and a dehumidification component B is set on the upper drum box part 201 to remove moisture and dust between the drum and the drum box.
[0029] By setting A and B air distribution devices beside the A and B far-infrared heating devices 206, the wind blown by the A and B air distribution devices cools down the A and B far-infrared heating devices 206, thereby increasing the service life of the A and B far-infrared heating devices 206; at the same time, the heated wind enters the area between the drum and the barrel box, accelerating the removal of moisture and dust in the barrel box. The far-infrared temperature detection device set at the inlet end of the drum is used to detect the temperature of the tea leaves in the drum during the aroma treatment, thereby improving the accuracy of temperature detection. The collecting conveyor belt 33 is used to collect the tea leaves discharged from each aroma machine 20, and then transferred to the tea wind classifier 31 through the B material transfer conveyor belt 32 for wind classification of the tea leaves. After the aroma machine 20 has been running for a period of time, the dust in the lower barrel box part 202 is removed by blowing air through the soot blowing nozzle 204 set on the aroma machine 20. The temperature measurement requirements of different types of tea leaves can be adapted by adjusting the direction of the infrared temperature measuring device.
[0030] There are still some difficulties in implementing the above-mentioned method in the traditional aromatizing machine, so the present invention also improves some defects of the traditional aromatizing machine 20 and provides a system for automated aromatizing processing.
[0031] Specific as Figure 1 , 2As shown, a tea automatic aroma treatment system includes a material distribution unit 10 for adding tea raw materials and feeding the aroma machine 20 according to the required quality; an aroma unit for aroma treatment of tea; a post-processing unit 30 for collecting the tea after aroma treatment and transporting it to the next process for post-processing; a detection unit, including monitoring the parameters of the aroma treatment, and a control unit 40 for setting the parameters of the aroma treatment, analyzing and processing the data detected by the detection unit, and regulating the operating status of each unit. The monitoring unit is composed of various sensors, such as temperature sensors, speed sensors, timers, etc. The control device can be a control cabinet, and a PLC control board is arranged in the control cabinet. The control board has been written into the corresponding operating program, so the operator can set and change the system parameters by pressing the button on the control cabinet, and the operation is convenient and fast. The above scheme provided by the present invention can realize the automatic aroma treatment of tea, improve the quality of tea and reduce the production cost of tea.
[0032] Specifically, the aroma machine is a drum-type far-infrared aroma machine. The aroma machine 20 includes an aroma machine frame 20, on which a barrel box and a drum rotatably installed in the barrel box are arranged.

The A and B dehumidification components can effectively improve the efficiency of aroma treatment and the amount of material in a single drum.
[0033] Detailed, such as Figure 3 , 4As shown, the A dehumidification component includes a dehumidification fan 218 disposed at the rear end of the fragrance drum, a dehumidification cover 211 is disposed on the outer side of the dehumidification fan 218, and a first dehumidification port is disposed at the top of the dehumidification cover 211. The dehumidification fan 218 is installed on the driving shaft that drives the drum to rotate, and the dehumidification cover 211 includes an upper cover body and a lower cover body, the upper cover body is an inverted bucket-shaped structure, and the lower cover body is an open box-shaped cover disposed at the rear end of the fragrance drum, and the upper part of the lower cover body is connected to the upper cover body as a whole. The B dehumidification component includes a vertically arranged second dehumidification port disposed on the upper part of the upper cylinder box 201. The second dehumidification port is arranged at intervals on the upper cylinder box 201 along the length direction of the drum. The upper part of the cover wall of the lower cover away from the drum is arranged in a mesh structure, that is, the connection with the upper cover is arranged in a mesh structure. It also includes a separator 217 for separating particles and dust from the smoke discharged by the A and B dehumidification components. The separator 217 includes a separation pipe arranged in a vertical shape, and a connection port for connecting the A and B dehumidification components is arranged in the middle of the separation pipe, and the upper end of the separation pipe constitutes a discharge port for exhausting smoke. A regulating plate valve 219 is arranged at the discharge port for adjusting the opening and closing size of the discharge port. A discharge port for discharging the separated and collected particles is arranged at the lower end of the separation pipe, and an opening and closing type dehumidification door is arranged at the discharge port. There are two second dehumidification ports, and the first and second dehumidification pipes arranged in a vertical shape are arranged on the second dehumidification port, respectively. The first and second connecting pipes are arranged oppositely on the pipe wall of the separation pipe, and the first and second connecting pipes are arranged obliquely and the inclination directions of the two are opposite. The lower end of the first connecting pipe 215 is connected to the upper end of the first dehumidification pipe 213 near the front end of the drum, and the first dehumidification port is connected to the lower end of the second connecting pipe 216 through the corrugated connecting pipe 212. The lower end of the second connecting pipe 216 is also connected to the upper end of the second dehumidification pipe 214 near the rear end of the drum. The regulating plate valve 219 is composed of a valve plate rotatably installed in the separation tube, and an adjusting handle for rotating the regulating valve plate is arranged outside the separation tube. The bottom of the separation tube is arranged in a blocking shape, and a debris discharge port is arranged at the bottom, and a plug-in-shaped debris discharge door is arranged at the outlet of the debris discharge port, and the debris discharge port is opened and closed by pulling and inserting the debris discharge door.
[0034] like Figure 5As shown, a further solution is that a cleaning device for cleaning the ash accumulated on the lower drum box portion 202 is provided. The lower drum box portion 202 has a U-groove structure inside, and the U-groove structure is used to accommodate the lower semicircle of the drum. An ash outlet is provided in the middle of the bottom of the U-groove structure, and an ash collecting trough for collecting dust is provided at the ash outlet. The cleaning device is used to move the dust accumulated at the bottom of the groove outside the ash outlet to the ash outlet for discharge. The height of each part around the bottom of the groove gradually decreases toward the ash outlet. The inner surface of the U-groove structure is an insulation layer. By blowing, the dust accumulated on the insulation layer can be blown to the ash outlet for discharge, thereby solving the problem of dust accumulation. Arc-shaped A and B plate portions are provided at both ends of the U-groove structure, and the cleaning device includes a ash blowing nozzle 204 provided on the A plate portion and the B plate portion. The intersection line of the A plate portion and the U-groove structure is marked as line A 203 (the intersection line of the A plate portion and the inner side of the U-groove structure, the same below), and the intersection line of the B plate portion and the U-groove structure is marked as line B. The soot blowing nozzle 204 is arranged adjacent to line A 203 and / or line B. The soot blowing nozzle 204 is arranged at intervals along line A 203 and / or line B. The cross-sectional size of the soot blowing nozzle 204 gradually decreases along the flow direction of the airflow. The direction of gas flow in the sootblower 204 is recorded as direction A, and the projection of direction A in the A1 plane is recorded as line A1. Line A1 is arranged obliquely and the end of the side close to the center of the drum is lower in height. The A1 plane is a plumb plane and the center line of the drum is located on the A1 plane. The projection of direction A in the A2 plane is recorded as line A2, and line A2 is a horizontal plane. A cover 205 is provided on the outside of the inlet end of the sootblower 204. The cover 205 is rotatably mounted on the A plate portion and / or the B plate portion. The cross section of the sootblower 204 is a quadrilateral shape (such as a mouth shape). In this way, after the aroma machine 20 has been running for a period of time, the cover 205 is opened, the outlet of the blower is connected to the air blowing nozzle, and the air is blown by the blower, so that the accumulated dust is gathered at the ash outlet for collection and discharge.
[0035] Two soot blowing nozzles 204 are respectively arranged on the A and B plate parts, and the first and second installation vacant parts are respectively arranged on the two side groove walls of the U groove structure, the height of the first installation vacant part is greater than the height of the second installation vacant part, and the A far-infrared heating device 208 arranged horizontally in the radiation heating direction is installed in the first installation vacant part, and the B far-infrared heating device 206 with the radiation heating direction obliquely pointing upward to the upper side of the first installation hole part is installed in the second installation vacant part, and the air blowing nozzle is arranged adjacent to the side wall on the side where the first installation vacant part is located. The two air blowing nozzles arranged on the A plate part are recorded as A1 and A2 air blowing nozzles, the height of the A1 air blowing nozzle matches the height of the lower side of the first vacant installation part, the height of the A2 air blowing nozzle is less than the height of the A1 air blowing nozzle, and the inclination of the gas flow direction in the A1 air blowing nozzle is greater than the inclination of the gas flow direction in the A2 air blowing nozzle. Similarly, the two blowing nozzles arranged on the B plate are denoted as B1 and B2 blowing nozzles. The height of the B1 blowing nozzle matches the height of the lower edge of the first vacant mounting portion. The height of the B2 blowing nozzle is less than that of the B1 blowing nozzle. The inclination of the gas flow direction in the B1 blowing nozzle is greater than that inclination of the gas flow direction in the B2 blowing nozzle. This arrangement can better meet the different cleaning requirements of different parts of the U-groove structure and ensure the reliability of cleaning. The ash collecting trough and the A and B far-infrared heating devices 206 are all drawer-type assembly.
[0036] like Figure 6 As shown, a further solution is as follows: the material distribution unit 10 includes a material distribution conveyor belt 13 and a material transfer conveyor belt 12 arranged in a horizontal shape, the aroma machine 20 is respectively arranged at both ends of the material distribution conveyor belt 13, the material transfer conveyor belt 12 is arranged at the discharge end and the middle part of the material distribution conveyor belt 13, and the material transfer conveyor belt 12 is provided with a feeding hopper 11 for adding tea raw materials at the feeding end. The material distribution conveyor belt 13 is installed on the material distribution bracket, and a weighing sensor 14 is arranged on the material distribution bracket.
[0037] The detailed operation is as follows: the aroma machine 20 is respectively set at the two ends of the material distribution conveyor belt 13, and the amount of material transferred to the material distribution conveyor belt 13 by the A material transfer conveyor belt 12 is detected by the weighing sensor 14. When the weight of the material accumulated on the material distribution conveyor belt 13 reaches the weight required by the aroma machine 20 for a single time, the A material transfer conveyor belt 12 stops transferring the material to the material distribution conveyor belt 13. At this time, the material distribution conveyor belt 13 is adjusted to rotate forward or reverse, so as to realize the reliable and orderly feeding of tea leaves into the two aroma machines 20. The height of the material distribution conveyor belt 13 is greater than the height of the aroma machine 20. The aroma machine 20 is set on the side of the material rack. The material distribution conveyor belt 13 is assembled on the material distribution bracket. The two ends of the material distribution bracket are respectively assembled and installed on the upper part of the material rack through the weighing sensor 14. The two sides of the material distribution conveyor belt 13 are provided with material baffles, and the two material baffles and the upper belt surface of the material distribution conveyor belt 13 form an open groove structure. The material transfer device is composed of a gooseneck conveyor belt, the lower end of the gooseneck conveyor belt is provided with a horizontally arranged loading section, the upper end of the gooseneck conveyor belt is provided with a horizontally arranged unloading section, the unloading section and the material distribution conveyor belt 13 are arranged vertically and correspondingly, and the middle part of the material distribution conveyor belt 13 receives the material unloaded from the unloading section. The feeding device is composed of a feeding hopper 11 arranged at the loading section, and the unloading section constitutes the bottom of the feeding hopper 11.
[0038] Two material distribution hoppers are also fixedly arranged on the material rack. The two material distribution hoppers are arranged at the two ends of the material distribution conveyor belt 13 respectively to receive the tea leaves unloaded from the two ends of the material distribution conveyor belt 13. The material distribution hopper includes a material distribution hopper body 15 and a material distribution conduit arranged at the bottom of the material distribution hopper body 15. The material distribution conduit is in a folded shape and includes a first guide section 16 and a second guide section 17. The upper end of the first guide section 16 is fixedly connected to the bottom of the material distribution hopper body 15. The inclination of the first guide section 16 matches the inclination of the bucket wall of the material distribution hopper body 15 away from the aroma machine 20. The inclination of the second guide section 17 is less than that of the first guide section 16. The lower end of the second guide section 17 extends to the middle of the upper drum of the aroma machine 20. The material distribution hopper is preferably implemented in the above manner. This operation mode can better guide the tea leaves and avoid the tea leaves blocking the material distribution conduit when the amount of tea leaves added is large. At the same time, it can be reliably avoided with the guide plate arranged at the front section of the drum to avoid affecting the unloading of the tea leaves. In this way, the radial dimension of the material distribution conduit can be set smaller to avoid affecting moisture discharge and temperature detection by the infrared temperature measuring device.
[0039] Further, such as Figure 7As shown, the upper barrel box part 201 is provided with A and B far-infrared heating devices 206, and the A and B air distribution devices are provided beside the A and B far-infrared heating devices 206. The airflow generated by the A and B air distribution devices is introduced into the barrel box after being preheated or heated by the A and B far-infrared heating devices 206. Through the A and B far-infrared heating devices 206, not only can the A and B far-infrared heating devices 206 be cooled, but also the dust and moisture in the aroma machine 20 can be discharged, thereby improving the aroma treatment effect of tea leaves. The heating direction of the A far-infrared heating device 208 is obliquely upward and points to the tea distribution area in the drum. The lower barrel box part 202 is provided with A and B installation chambers, and the A installation chamber is connected to the inside of the barrel box through the A installation vacant part provided on the lower barrel box part 202, and the A far-infrared heating device 208 and the A air distribution device are installed in the A installation chamber. The A far-infrared heating device 208 is installed on a sliding bracket, a sliding rail is provided in the A installation chamber, and the sliding bracket is slidably installed in the sliding rail in a horizontal direction perpendicular to the center line of the drum. The wall of the A installation chamber away from the drum is arranged to be composed of a detachable A installation plate, and the A air distribution device is installed on the A installation plate. The A air distribution device is composed of the A fans 209 arranged on the A installation plate. The heating direction of the B far-infrared heating device 206 is horizontally directed to the tea cloth area in the drum. The B installation chamber is connected to the inside of the drum box through the B installation vacant part provided on the lower drum box part 202, and the B far-infrared heating device 206 and the B air distribution device are installed in the B installation chamber. The B air distribution device is composed of the B fans 207 respectively provided on the two B chamber walls, and the two B chamber walls are two chamber walls arranged perpendicular to the center line of the drum on the B installation chamber. The B far-infrared heating device 206 can also be adjusted and assembled in a horizontal direction perpendicular to the center line of the drum. In detail, three A fans 209 are arranged on the A mounting plate, and two B fans 207 are arranged on each B side wall. This distribution mode can better achieve the functions of heat dissipation, dust removal and moisture discharge, and at the same time can make the structure of the entire device more compact.
[0040] A further solution is that the post-processing unit 30 includes a collecting conveyor belt for collecting the tea leaves unloaded from the aroma machine 20 and a B transfer conveyor belt 32, the discharge end of the collecting conveyor belt and the feed end of the B transfer conveyor belt 32 are arranged correspondingly, and the discharge end of the B transfer conveyor belt 32 is connected to a tea sorting machine.
