Description

Technical Field

[0001] This utility model relates to the field of agricultural product processing equipment technology, and in particular to a bee pollen drying device. Background Technology

[0002] Bee pollen is a natural nutritional product formed by bees collecting plant pollen, mixing it with saliva and nectar. It is rich in protein, vitamins, minerals, and active ingredients, and has high nutritional and medicinal value. However, fresh bee pollen has a high water content, and if not dried promptly, it is prone to mold growth and spoilage. Therefore, drying is a crucial step in bee pollen processing, requiring a rapid and uniform reduction of its moisture content while ensuring the preservation of its nutritional components.

[0003] Currently, several bee pollen drying devices have been proposed. One such device, with publication number CN210425896U, combines heating and stirring. A stirring mechanism continuously agitates the bee pollen during drying to improve uniformity. However, this device still has limitations in practical use: due to the fixed movement of the stirring mechanism, the bee pollen is unevenly distributed inside the drying chamber. The heating element is only located within the inner wall of the drying tank, resulting in lower drying efficiency for the pollen in the central area and faster drying at the edges, leading to an overall uneven drying effect. Utility Model Content

[0004] To overcome the drawback of uneven drying, this invention provides a device for uniformly drying bee pollen.

[0005] A bee pollen drying device includes a drying tank with a detachable maintenance assembly in the middle. A feed hopper is connected to the top of the drying tank. A first motor and a hot air blower are installed on the top of the drying tank. A hollow rotating rod is rotatably connected inside the drying tank. The top of the hollow rotating rod is connected to the output shaft of the first motor, and an air inlet is opened at the upper end of the hollow rotating rod. One end of an air supply pipe wraps around the hollow rotating rod, and the other end is connected to the air outlet of the hot air blower. The air supply pipe is rotatably connected to the hollow rotating rod, and both ends of the air supply pipe are sealed. Several stirring rods are connected to the hollow rotating rod, and the stirring rods are in communication with the interior of the hollow rotating rod. A baffle is sealed at the end of each stirring rod. An intermittent venting assembly is provided at the lower end of the drying tank to seal the through hole at the bottom of the hollow rotating rod.

[0006] Furthermore, it is particularly preferred that the intermittent venting assembly includes a time relay, a mounting plate is connected to the lower end of the drying tank, the time relay and a second motor are mounted on the bottom of the mounting plate, the time relay is wired to the second motor, the output shaft of the second motor is connected to the sealing plate, and the sealing plate is sealed to the bottom of the hollow rotating rod.

[0007] Furthermore, it is particularly preferred that the outer ring of the sealing plate is fitted with a sealing gasket.

[0008] In addition, particularly preferably, it also includes an exhaust pipe, one end of which is connected to the bottom of the dryer and wraps around the intermittent venting assembly and the hollow rotating rod, and the other end is bent around the dryer and vents upward.

[0009] Furthermore, it is particularly preferred that the device also includes a pull rope, one end of which is connected to the stirring rod and the other end of which is connected to the baffle.

[0010] Furthermore, it is particularly preferred that the stirring rod has a transparent observation window on its side.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. By combining the hollow rotating rod, stirring rod, and hot air blower, hot air is evenly distributed inside the stirring rod, forming a dynamic heat conduction structure, achieving simultaneous heating of bee pollen inside and out, and ultimately achieving uniform drying.

[0013] 2. By using the intermittent venting component, the sealing plate opens and closes periodically, forming a pulsed hot air circulation, which achieves efficient replacement of waste gas and ultimately achieves the purpose of energy saving and efficiency improvement.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: A bee pollen drying device, such as Figures 1-5 As shown, the system includes a drying tank 1, a maintenance assembly 2, a feed hopper 3, a first motor 4, a hollow rotating rod 5, a stirring rod 6, a baffle 7, a hot air blower 8, an air supply pipe 9, and an intermittent venting assembly 11. The drying tank 1 has a detachable maintenance assembly 2 in the middle, which mainly consists of two sealed arc plates enclosing the middle part of the drying tank 1. Both the maintenance assembly 2 and the bottom of the drying tank 1 are equipped with heating pipes to heat the interior. The bottom of the drying tank 1 has a discharge port, and the top of the drying tank 1 is connected to the feed hopper 3. The top of the drying tank 1 is equipped with the first motor 4 and the hot air blower 8. A hollow rotating rod 5 is rotatably connected inside the drying tank 1, and the top of the hollow rotating rod 5 is connected to the first motor 4. The output shaft of motor 4 is connected, and multiple air inlets 10 are opened around the upper end of hollow rotating rod 5. One end of air supply pipe 9 is sleeved on the outside of the air inlet 10 of hollow rotating rod 5, and the other end is connected to the air outlet of hot air blower 8. Air supply pipe 9 is rotatably connected to hollow rotating rod 5, and both ends of air supply pipe 9 are sealed to other components to ensure the utilization rate of hot air flow. Nine stirring rods 6 are connected to hollow rotating rod 5, with three stirring rods 6 forming a layer. The angle between stirring rods 6 is 60 degrees, and stirring rods 6 are connected to the inside of hollow rotating rod 5. Baffles 7 are sealed at the ends of stirring rods 6. An intermittent venting component 11 that seals the bottom through hole of hollow rotating rod 5 is provided at the lower end of drying tank 1.

[0022] like Figure 2 and Figure 5As shown, the intermittent venting assembly 11 includes a mounting plate 111, a time relay 112, a second motor 113, and a sealing plate 114. The mounting plate 111 is connected to the lower end of the drying tank 1. The time relay 112 and the second motor 113 are mounted on the bottom of the mounting plate 111. The time relay 112 is wired to the second motor 113. The output shaft of the second motor 113 is connected to the sealing plate 114. The sealing plate 114 is sealed to the bottom of the hollow rotating rod 5. The time relay 112 periodically starts the second motor 113 according to a preset program, driving the sealing plate 114 to reciprocate. When the sealing plate 114 rotates to the closed position, its end face is tightly fitted with the bottom end face of the hollow rotating rod 5, forming a closed space, forcing hot air to remain inside the hollow rotating rod 5 and the stirring rod 6 for continuous heat conduction. When rotated to the open position, the sealing plate 114 separates from the end face to form an exhaust gap, and the accumulated waste gas is rapidly discharged through the exhaust pipe 13 under the action of air pressure. This intermittent motion forms a pulsed heat exchange mode, which both prolongs the residence time of hot air and ensures timely renewal of exhaust gas.

[0023] like Figure 5 As shown, it also includes a sealing gasket 12. The sealing plate 114 is fitted with a sealing gasket 12 on its outer ring. The sealing gasket 12 is made of high-temperature resistant silicone material and undergoes elastic deformation during the rotation and closing process of the sealing plate 114.

[0024] like Figure 2 As shown, it also includes an exhaust pipe 13, one end of which is connected to the bottom of the dryer tank 1 and wraps around the intermittent venting assembly 11 and the hollow rotating rod 5, while the other end bends around the dryer tank 1 and exhausts upwards.

[0025] like Figure 4 As shown, it also includes a pull rope 14, one end of which is fixed to the stirring rod 6 and the other end is connected to the baffle 7. The pull rope 14 is made of stainless steel wire braided structure, which ensures that the baffle 7 can be completely separated from the stirring rod 6 for drainage operation, and also prevents the parts from falling due to accidental slippage.

[0026] like Figure 4 As shown, it also includes an observation window 15, and the side of the stirring rod 6 is provided with an observation window 15 made of transparent material.

[0027] The staff pours the bee pollen to be dried into the drying tank 1 through the feed hopper 3, and then turns on the first motor 4 and the hot air blower 8. The hot air provided by the hot air blower 8 enters the hollow rotating rod 5 through the air supply pipe 9, and is dispersed along the hollow rotating rod 5 into the stirring rod 6, thereby increasing the temperature of the hollow rotating rod 5 and the stirring rod 6. The first motor 4 drives the hollow rotating rod 5 and the stirring rod 6 to rotate, and together with the heating equipment inside the drying tank 1, the bee pollen is heated from multiple directions. The bee pollen in the middle can also absorb the heat from the hollow rotating rod 5 and the stirring rod 6, evaporate its own moisture, and achieve drying. The evaporated moisture escapes from the feed hopper 3 at the top.

[0028] To further ensure the utilization rate of hot air, time relay 112 controls the opening and closing of the second motor 113 to achieve intermittent rotation of the sealing plate 114. When the sealing plate 114 contacts the bottom of the hollow rotating rod 5, the airflow stays inside the hollow rotating rod 5 and the stirring rod 6. After the sealing plate 114 separates from the hollow rotating rod 5, the airflow is ejected from the bottom of the hollow rotating rod 5 and connects to the outside along the exhaust pipe 13. The sealing gasket 12 can optimize the sealing effect between the sealing plate 114 and the hollow rotating rod 5. After the bee pollen is dried, all electrical equipment is kept on except for the first motor 4. The outlet of the drying tank 1 is opened, and the dried bee pollen enters the collection container from the outlet. Finally, the first motor 4 is turned off.

[0029] The hot air contains a certain amount of moisture. When the hot air comes into contact with the cold stirring rod 6, it releases heat, and the water vapor condenses into water droplets, which eventually gather at the end of the stirring rod 6. After the drying tank 1 finishes drying, the drying tank 1 is opened through the maintenance component 2, and the baffle 7 is removed to collect the moisture inside the stirring rod 6. When removing the baffle 7, the pull rope 14 can hang the baffle 7 to prevent it from being lost. Before opening the baffle 7, the observation window 15 is used to observe and understand the water accumulation of different stirring rods 6. The stirring rods 6 with water accumulation are collected. After the water accumulation is cleaned up, the baffle 7 is covered, and the drying tank 1 is sealed through the maintenance component 2.

[0030] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
