Description

Technical Field

[0001] This utility model relates to the field of spray drying technology, and more specifically, to a spray dryer for solid beverage production. Background Technology

[0002] A spray dryer is a device that can simultaneously dry and granulate. The pressure, flow rate, and nozzle size of the feed pump can be adjusted according to process requirements to obtain spherical particles of a specific size ratio. The spray dryer is a type of continuous atmospheric pressure dryer. It uses special equipment to spray liquid material into a mist, allowing it to contact hot air and be dried. It is used to dry some heat-sensitive liquids, suspensions, and viscous liquids, such as milk, eggs, tannins, and pharmaceuticals. It is also used to dry fuels, intermediates, soap powder, and inorganic salts.

[0003] However, the air intake of existing spray dryers is fixed. The air intake cannot be changed during use, as this would affect normal operation and thus reduce the working efficiency of the spray dryer. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a spray dryer for solid beverage production, which can easily adjust the size of the air vent and thus adjust the air volume entering from the air vent, thereby improving the working efficiency of the spray dryer.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a spray dryer for solid beverage production, comprising a machine body, an air volume regulating component provided at the air outlet of the machine body, the air volume regulating component comprising a rotating disk and a fixed disk provided at the air outlet, a plurality of fixed plates rotatably connected to the fixed disk, a plurality of rotating rods rotatably connected between the fixed plates and the rotating disk, and a drive component for driving the rotating disk to rotate within the machine body, the fixed disk having a spray outlet communicating with the air outlet inside, the plurality of fixed plates being arranged in a circular array on the fixed disk and used to block the spray outlet, the machine body having a cavity for the air volume regulating component to move within, the rotating disk being rotatably connected within the cavity, the fixed disk being fixedly connected within the cavity, and the drive component driving the rotating disk to rotate within the cavity, thereby causing the fixed plates to rotate on the fixed disk.

[0006] By adopting the above technical solution, when the spray dryer is not in use, several fixed plates are located on the fixed plate and block the spray outlet. When the spray dryer needs to be used, the operator adds the solid beverage raw materials to be processed into the machine body through the feed inlet, and then turns on the drive component of the air volume adjustment component. This causes the drive component to drive the rotating plate to rotate in the cavity, which in turn drives several rotating rods to rotate. These rotating rods then pull the fixed plates on the fixed plate to rotate, thus no longer blocking the spray outlet. After adjusting to a suitable spray outlet size, the drive component is turned off, and the rotating plate and rotating rods... The moving rod and fixed plate no longer rotate, so the opening of the drive component drives the rotation of the rotating disk, which in turn drives several rotating rods to pull several fixed plates to rotate. The rotating disk can be adjusted to different angles to open and close several fixed plates on the fixed plate. The fixed plates can completely cover the spray outlet or completely open the spray outlet, and can also partially block the spray outlet to adjust the amount of spray entering the spray outlet. This allows for adjustment of the air volume of the spray dryer, thereby adjusting the processing efficiency of solid beverages and improving the working efficiency and effect of solid beverage processing.

[0007] The present invention is further configured such that the inner diameter of the spray outlet is the same as the inner diameter of the air vent of the machine body.

[0008] By adopting the above technical solution, when several fixed plates do not block the spray outlet, the air inlet of the machine body corresponds to the spray outlet, so as to realize a large amount of spraying in the spray dryer to improve the efficiency of solid beverage processing. Then, the spray volume of the spray dryer can be adjusted by adjusting the diameter of the spray outlet through the function of the air volume adjustment component.

[0009] The present invention is further configured such that: the driving component includes a motor disposed in the machine body and a gear fixedly connected to the output shaft of the motor; a plurality of locking teeth that mesh with the gear blocks are provided on the outer peripheral wall of the rotating disk; and the plurality of locking teeth are distributed in a ring array on the rotating disk.

[0010] By adopting the above technical solution, the operator turns on the motor using a reversing switch, causing the motor to rotate and drive the gears to rotate within the cavity. The gears then mesh with several teeth on the outer wall of the rotating disk, causing the disk to rotate within the cavity. This, in turn, causes the rotating rods and fixed plates to rotate, opening the spray outlet. The diameter of the spray outlet increases, and once adjusted to a suitable size, the motor is turned off. When the spray outlet diameter needs to be adjusted again, the reversing switch is pressed again, causing the motor's output shaft to rotate in the opposite direction. The gears then rotate clockwise, driving the rotating disk. This rotation of the disk drives several rotating rods, and the fixed plates, along with the rotating disk, block the spray outlet, reducing its diameter. This adjustment continues until the spray dryer is no longer in use, and the motor, along with the rotating disk, blocks the spray outlet, thus adjusting the spray volume and improving the efficiency and quality of solid beverage production.

[0011] The present invention is further configured such that: a plurality of limiting rods are provided in the cavity, and a limiting groove is provided on the rotating disk for the limiting rods to move.

[0012] By adopting the above technical solution, several limiting rods are inserted into the limiting grooves opened on the rotating disk. As the rotating disk rotates, and the rotating disk is always inserted into the limiting rods, the stability of the rotating disk during rotation can be guaranteed by the action of several limiting rods. The fixed plates will also be more stable when opening and closing the spray outlet.

[0013] The present invention is further configured such that: a plurality of balls are provided in the limiting groove and are in contact with the outer wall of the limiting rod, and the plurality of balls are rotatably connected in the rotating disk.

[0014] By adopting the above technical solution, when the rotating disk rotates with the rotation of the gear, the limiting rod will contact several balls and cause the balls to roll. The rotating disk will rotate while the balls are in contact with the limiting rod, thus ensuring the smoothness of the rotating disk's rotation. This will make the opening and closing of the adjusting plate smoother, thereby enabling the timely opening and closing of the spray outlet and adjusting the diameter of the spray outlet.

[0015] The present invention is further configured such that: a fixing block with a diameter larger than the limiting groove is provided at the end of the limiting rod away from the rotating disk.

[0016] By adopting the above technical solution, the setting of the fixing block can prevent the limiting rod from separating from the limiting groove when it moves in the limiting groove. This not only ensures the stability of the rotating disk when it moves, but also ensures the stability of the fixing plate when it opens and closes.

[0017] The present invention is further configured such that each of the aforementioned fixing plates has a plurality of ventilation holes.

[0018] By adopting the above technical solution, the setting of several vent holes can facilitate the spray from the spray dryer to pass through the vent holes opened in the fixed plate, thereby improving the spray discharged by the air volume regulating component.

[0019] The present invention is further configured such that each of the aforementioned fixing plates has an inclined surface in the direction of the air outlet.

[0020] By adopting the above technical solution, the inclined plane allows the spray from the spray dryer to be sprayed in the direction of the inclined plane, so that the inclined plane can play a certain guiding role.

[0021] In summary, this utility model has the following beneficial effects: under the action of the air volume adjustment component, it is possible to conveniently adjust the size of the air outlet and thus adjust the air volume entering from the air outlet, thereby improving the working efficiency of the spray dryer and facilitating the adjustment of air volume to improve the production efficiency of solid beverages.

[0029] The present invention will now be described in detail with reference to the accompanying drawings.

[0030] A spray dryer for solid beverage production, referenced Figures 1-3 The system includes a body 1, and an airflow regulating component is provided at the air outlet 4 of the body 1. The airflow regulating component includes a rotating disk 2 and a fixed disk 3 located at the air outlet 4, several fixed plates 8 rotatably connected to the fixed disk 3, several rotating rods 9 rotatably connected between the fixed plates 8 and the rotating disk 2, and a drive component for driving the rotating disk 2 to rotate within the body 1. The fixed disk 3 has a spray outlet communicating with the air outlet 4 inside. Several fixed plates 8 are arranged in a ring array on the fixed disk 3 and are used to block the spray outlet. The body 1 has a cavity 5 for the airflow regulating component to move within. The rotating disk 2 is rotatably connected within the cavity 5, and the fixed disk 3 is fixedly connected within the cavity 5. The drive component drives the rotating disk 2 to rotate within the cavity 5, which can drive the fixed plates 8 to rotate on the fixed disk 3. The inner diameter of the spray outlet is the same as the inner diameter of the air outlet 4 of the body 1.

[0031] The drive assembly includes a motor installed inside the body 1 and a gear 7 fixedly connected to the output shaft of the motor. The outer peripheral wall of the rotating disk 2 is provided with a number of teeth that mesh with the tooth blocks. The teeth are arranged in a ring array on the rotating disk 2.

[0032] The cavity 5 is provided with several limiting rods 11. The rotating disk 2 is provided with a limiting groove 10 for the limiting rods 11 to move. Several balls are provided in the limiting groove 10 and are in contact with the outer wall of the limiting rods 11. The balls are rotatably connected in the rotating disk 2. A fixing block 6 with a diameter larger than the limiting groove 10 is provided at the end of the limiting rod 11 away from the rotating disk 2.

[0033] Several fixed plates 8 are provided with several ventilation holes 12, and several fixed plates 8 are provided with inclined surfaces in the direction of the air outlet 4.

[0034] Working principle: When the spray dryer is not in use, several fixed plates 8 are located on the fixed plate 3 and block the spray outlet. When the spray dryer needs to be used, the operator adds the solid beverage raw materials to be processed into the machine body 1 through the feed inlet, and then turns on the drive component of the air volume adjustment component. This causes the drive component to drive the rotating plate 2 to rotate in the cavity 5, which in turn drives several rotating rods 9 to rotate. The rotating rods 9 then pull the fixed plates 8 on the fixed plate 3 to rotate, no longer blocking the spray outlet. After adjusting to a suitable spray outlet size, the drive component is turned off, and the rotating plate 2 and rotating rods 9... And the fixed plate 8 no longer rotates, so that the opening of the drive component drives the rotation of the rotating disk 2, which in turn drives several rotating rods 9 to pull several fixed plates 8 to rotate. The rotating disk 2 can be adjusted to different angles to open and close several fixed plates 8 on the fixed disk 3. The fixed plates 8 can completely cover the spray outlet or completely open the spray outlet. At the same time, they can also partially cover the spray outlet to adjust the amount of spray entering the spray outlet. This allows the air volume of the spray dryer to be adjusted, thereby adjusting the processing efficiency of solid beverages and improving the working efficiency and effect of solid beverage processing.

[0035] The operator turns on the motor using the reversing switch, causing it to rotate. This rotation drives gear 7 within cavity 5, which in turn meshes with several teeth on the outer wall of rotating disk 2, causing disk 2 to rotate within cavity 5. Disk 2 then rotates rotating rod 9 and fixing plate 8, opening the spray outlet. The nozzle diameter increases, and once adjusted to a suitable size, the motor is turned off. To readjust the nozzle diameter, the reversing switch is pressed again. When the output shaft of the drive motor rotates in the reverse direction, the gear 7 changes from rotating counterclockwise to clockwise, driving the rotating disk 2 to rotate. The rotation of the rotating disk 2 at this time will drive several rotating rods 9 to rotate, and several fixed plates 8 will block the spray outlet as the rotating disk 2 rotates. At this time, the diameter of the spray outlet is reduced, thereby adjusting the diameter of the spray outlet. Until the spray dryer is no longer used, the drive motor will block the spray outlet with several fixed plates 8 as the rotating disk 2 rotates, thereby adjusting the spray volume of the spray dryer and improving the efficiency and quality of solid beverage production.

[0036] Several limiting rods 11 are inserted into the limiting grooves 10 opened in the rotating disk 2. As the rotating disk 2 rotates, and the rotating disk 2 is always inserted into the limiting rods 11, the stability of the rotating disk 2 during rotation can be guaranteed by the action of several limiting rods 11. The fixed plates 8 are also more stable when opening and closing the spray outlet.

[0037] When the rotating disk 2 rotates with the rotation of the gear 7, the limiting rod 11 will contact several balls and cause the balls to roll. The rotating disk 2 will rotate while the balls are in contact with the limiting rod 11, thus ensuring the smooth rotation of the rotating disk 2. This also makes the opening and closing of the adjusting fixing plate 8 smoother, allowing the spray outlet to be opened and closed in a timely manner and the diameter of the spray outlet to be adjusted. The setting of the fixing block 6 prevents the limiting rod 11 from separating from the limiting groove 10 when it moves within the limiting groove 10. This not only ensures the stability of the rotating disk 2 during movement but also the stability of the fixing plate 8 when it opens and closes.

[0038] The arrangement of several vent holes 12 allows the spray from the spray dryer to pass through the vent holes 12 on the fixed plate 8, thereby improving the spray discharged by the air volume regulating component. The inclined surface allows the spray from the spray dryer to be sprayed in the direction of the inclined surface, so that the inclined surface can play a certain guiding role.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
