Description

Technical Field

[0001] This utility model relates to the field of hesperidin production technology, and in particular to a hesperidin spray drying device. Background Technology

[0002] Hesperidin is an extract from the dried young fruit of *Citrus aurantium* and its cultivated varieties or sweet orange, belonging to the Rutaceae family. In some hesperidin production processes, the young fruit powder and the extract are mixed in a certain proportion to form a stock solution. The stock solution is then refined and spray-dried to finally obtain hesperidin powder.

[0003] Traditional drying methods involve using spray drying equipment to dry the raw liquid. Spray drying equipment includes a tower with atomizing nozzles at the top and a cyclone separator at the bottom. The raw liquid is transported to the atomizing nozzles via pipeline, atomized, and sprayed into the tower, while simultaneously, high-temperature drying gas is introduced into the tower. The high-temperature drying gas exchanges heat with the atomized water droplets, causing the water droplets to evaporate and yield hesperidin powder, while the drying gas becomes moistened. Finally, the cyclone separator separates the hesperidin powder from the gas.

[0004] However, during the spray drying process, relying solely on the diffusion and heat exchange between the high-temperature drying gas and water mist within the tower results in some of the high-temperature drying gas being discharged from the cyclone separator without being effectively utilized, leading to a waste of resources. Utility Model Content

[0005] In view of the above problems, this utility model provides a spray drying device for hesperidin.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A hesperidin spray drying device is provided, comprising a tower body, a feed pipe for injecting raw liquid at the top of the tower body, one end of the feed pipe extending into the tower body and connected to an atomizing nozzle, an air duct for introducing drying hot air on the side wall of the tower body, a hot air blower connected to one end of the air duct, a cyclone separator connected to the bottom of the tower body, an air outlet pipe at the top of the cyclone separator and a material collection device connected to the bottom, a stirring roller for stirring and mixing drying hot air and water mist rotatably arranged below the air duct and the atomizing nozzle in the tower body, a blocking component for prolonging the residence time of hot air in the tower body is also provided below the stirring roller in the tower body, and a first driving component for driving the stirring roller to rotate on the tower body.

[0008] Furthermore, the blocking component includes multiple baffles, which are staggered on the inner walls of both sides of the tower body in a vertical direction. The baffles are inclined so that the end of the baffle closest to the side wall of the tower body is higher than the other end of itself, and the multiple baffles form a flow guiding channel inside the tower body.

[0009] Furthermore, the tower body is equipped with a vibration assembly for shaking off hesperidin powder. The vibration assembly includes multiple hammers, and multiple mounting plates corresponding to the hammers are provided on the outer wall of the tower body. The multiple hammers are horizontally and linearly slidably mounted on the corresponding mounting plates. The mounting plates are equipped with a second driving component for driving the hammers to move and strike the tower body to vibrate.

[0010] Furthermore, the tower body is provided with a heating device for heating the stirring roller. The heating device includes an electric heating rod. The rotating shaft of the stirring roller is horizontal, and the stirring roller is rotatably connected to the inner wall of one side of the tower body. An installation groove is opened at the end of the stirring roller away from the first driving member. The electric heating rod is horizontally arranged on the inner wall of the other side of the tower body, and one end of the electric heating rod extends into the installation groove.

[0011] Furthermore, the collection device includes two collection boxes, a discharge pipe at the bottom of the cyclone separator, two branch pipes on the discharge pipe for connecting the two collection boxes respectively, and valves on both branch pipes. A drawer for collecting hesperidin powder is horizontally and linearly slidably installed inside the collection box.

[0012] Furthermore, the drawer is equipped with a heating plate for heating the hesperidin powder.

[0013] The beneficial effects of this invention are as follows: When the drying hot air and water mist exchange heat, rotating the stirring roller can fully mix the drying hot air and water mist, preventing some hot air from being discharged unused, thus improving the utilization rate of hot air and saving resources; after the water mist is heated and dried, the hesperidin powder inside is precipitated and can enter the cyclone separator along with the moist hot air for separation. The hot air is discharged from the outlet pipe, while the hesperidin powder is retained in the collection device; during the drying process, the blocking component can prolong the residence time of the hot air in the tower, thereby reducing the heat loss in the tower.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] This application discloses a hesperidin spray drying device, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a tower body 1, with a feed pipe 2 at the top for injecting the raw liquid. One end of the feed pipe 2 extends into the tower body 1 and is connected to an atomizing nozzle 21. A duct 3 for introducing hot drying air is installed on the side wall of the tower body 1, with a hot air blower 31 connected to one end of the duct 3. A cyclone separator 4 is connected to the bottom of the tower body 1, with an air outlet pipe 41 at the top and a material collection device at the bottom. An agitator roller 6 is rotatably installed inside the tower body 1, below the duct 3 and the atomizing nozzle 21, for mixing the hot drying air and water mist. Below the agitator roller 6, a baffle is installed inside the tower body 1 to prolong the residence time of the hot air within the tower body 1. A first driving component 8 is installed on the tower body 1 to drive the agitator roller 6 to rotate.

[0021] In this embodiment, the raw liquid can be injected into the atomizing nozzle 21 through the feed pipe 2, and atomized into water mist through the atomizing nozzle 21. Simultaneously, high-temperature drying hot air can be introduced into the tower body 1 through the hot air blower 31. During heat exchange between the drying hot air and the water mist, rotating the stirring roller 6 ensures thorough mixing of the drying hot air and water mist, preventing unused hot air from being discharged, thus improving hot air utilization and saving resources. After the water mist is heated and evaporated, the hesperidin powder within it precipitates out and can enter the cyclone separator 4 along with the moistened hot air for separation. The hot air is discharged from the exhaust pipe 41, while the hesperidin powder remains in the collection device. During the drying process, the obstruction device prolongs the residence time of the hot air in the tower body 1, thereby reducing heat loss within the tower body 1.

[0022] Specifically, the blocking component includes multiple baffles 7, which are staggered vertically on the inner walls of both sides of the tower body 1. The baffles 7 are inclined so that the end of the baffle 7 closest to the side wall of the tower body 1 is higher than the other end of itself, and the multiple baffles 7 form a flow guiding channel inside the tower body 1.

[0023] In this embodiment, the flow path of hot air within the tower 1 can be extended via the guide channel, thereby prolonging the hot air residence time. Simultaneously, some of the precipitated hesperidin powder can fall onto the baffle 7 and then along the guide channel into the cyclone separator 4 below.

[0024] Furthermore, the tower body 1 is equipped with a vibration assembly for shaking off hesperidin powder. The vibration assembly includes multiple hammers 9, and multiple mounting plates 20 corresponding to each hammer 9 are welded to the outer wall of the tower body 1. The multiple hammers 9 are horizontally and linearly slidably mounted on the corresponding mounting plates 20, and the mounting plates 20 are equipped with a second driving member 10 for driving the hammers 9 to move and strike the tower body 1 to vibrate.

[0025] In this embodiment of the application, during the spray drying process of hesperidin, multiple hammers 9 reciprocate to strike the outer wall of the tower body 1, which causes the tower body 1 to vibrate, so that the hesperidin powder remaining on the inner wall of the tower body 1 and the baffle 7 can fall into the cyclone separator 4 below, thereby improving the utilization rate of hesperidin powder.

[0026] Furthermore, a heating device for heating the stirring roller 6 is provided inside the tower body 1. The heating device includes an electric heating rod 30, the shaft of the stirring roller 6 is horizontal, and the stirring roller 6 is rotatably connected to the inner wall of one side of the tower body 1. A mounting groove 61 is provided at the end of the stirring roller 6 away from the first driving member 8, and the electric heating rod 30 is horizontally arranged on the inner wall of the other side of the tower body 1, with one end of the electric heating rod 30 extending into the mounting groove 61.

[0027] In this embodiment, the stirring roller 6 is rotatably connected to one side wall of the tower body 1, and the electric heating rod 30 is fixedly connected to the other side wall of the tower body 1, allowing the stirring roller 6 to rotate relative to the electric heating rod 30. During the rotation of the stirring roller 6, the electric heating rod 30 can heat the stirring roller 6, further improving the heating efficiency of the water mist.

[0028] In this embodiment, the first driving component 8 includes a drive motor, which is mounted on the outer wall of the tower body 1, and the output shaft of the drive motor is connected to the stirring roller 6 for transmission. The second driving component 10 includes a drive cylinder, which is horizontally mounted on the mounting plate 20, and the piston rod of the drive cylinder is bolted to the hammer 9.

[0029] Reference Figure 4 The collection device includes two collection boxes 5. A discharge pipe 42 is provided at the bottom of the cyclone separator 4. Two branch pipes 43 are provided on the discharge pipe 42 to connect the two collection boxes 5 respectively. Each branch pipe 43 is equipped with a valve 431. A drawer 51 for collecting hesperidin powder is horizontally and linearly slidably arranged inside the collection box 5.

[0030] In this embodiment, the two valves 431 are opened and closed alternately, allowing the two collection boxes 5 to collect hesperidin powder from the tower body 1 in turn. When the valve 431 on one branch pipe 43 is closed, the operator can remove the drawer 51 and take out the hesperidin powder. At this time, the valve 431 on the other branch pipe 43 is opened, and the corresponding collection box 5 can continue to collect the powder.

[0031] To ensure that the hesperidin powder in the collection box 5 remains dry, a heating plate 52 for heating the hesperidin powder is provided in the drawer 51.

[0032] The implementation principle of the hesperidin spray drying equipment in this application embodiment is as follows: When the drying hot air and water mist exchange heat, rotating the stirring roller 6 can fully mix the drying hot air and water mist, avoiding the discharge of some hot air without being utilized, thus improving the utilization rate of hot air and saving resources; after the water mist is heated and dried, the hesperidin powder in it is precipitated and can enter the cyclone separator 4 along with the moist hot air for separation. The hot air is discharged from the air outlet pipe 41, while the hesperidin powder is retained in the collection device; during the drying process, the residence time of the hot air in the tower body 1 can be extended by passing through the blocking component, thereby reducing the heat loss in the tower body 1.
