Description

Technical Field

[0001] This application relates to the technical field of bee pollen processing equipment, specifically to a continuous bee pollen drying device. Background Technology

[0002] Bee pollen is a pollen-like substance collected by bees from plant flowers and processed by them. It is rich in nutrients such as protein, amino acids, and vitamins, and is widely used in food, health products, and cosmetics. Drying is a crucial step in the processing of bee pollen.

[0003] Traditional methods of drying bee pollen have several problems. For example, natural sun-drying is not only time-consuming and susceptible to weather conditions, but also makes the pollen vulnerable to contamination from dust and impurities, affecting product quality. Existing drying equipment is often intermittent, unable to achieve continuous production and resulting in low efficiency. Furthermore, some drying equipment dries bee pollen unevenly, leading to over-drying and nutrient loss in some areas, while under-drying affects subsequent storage and use. In addition, existing drying equipment is not energy efficient, resulting in energy waste and increased production costs. Therefore, developing a continuous bee pollen drying device that achieves continuous, uniform drying and high energy efficiency is of significant practical importance. Utility Model Content

[0004] This invention addresses the problems of long drying time, low efficiency, uneven drying, and energy waste in existing bee pollen drying processes by providing a continuous bee pollen drying device.

[0005] The objective of this utility model is mainly achieved through the following solution:

[0006] A continuous bee pollen drying device includes a hollow drying chamber with a shelf for holding bee pollen inside. A feed inlet is located on one side of the drying chamber, and a cover is movably connected to the feed inlet. A horizontally arranged air inlet pipe is connected to the side of the drying chamber opposite to the feed inlet. A circulating air pipe is connected to the top of the end of the air inlet away from the feed inlet, and the other end of the circulating air pipe is connected to the top of the drying chamber near the feed inlet. A heating element and a draft fan element are sequentially arranged inside the air inlet pipe along the airflow direction.

[0007] Preferably, the shelf includes multiple shelves arranged from top to bottom, with gaps between adjacent shelves for placing bee pollen, and multiple through holes evenly distributed on the shelves.

[0008] Preferably, the end of the air inlet pipe near the drying chamber is connected to an enlarged section, which connects to the interior of the drying chamber. The enlarged section has a hollow frustum-shaped structure, and its diameter gradually increases along the direction of airflow.

[0009] Preferably, support frames are installed on both sides of the bottom of the air intake pipe, and the top of each support frame is provided with an arc-shaped plate that matches the outer wall of the air intake pipe, and the support frame and the air intake pipe are fixed by the arc-shaped plate.

[0010] Preferably, the heating components are provided in two groups along the length of the air intake pipe, and each group of heating components includes a multi-layer filter screen plate arranged along the length of the air intake pipe. An electric heating rod is connected between the multi-layer filter screen plates in each group, and multiple electric heating rods are evenly arranged circumferentially along the axial direction of the filter screen plate.

[0011] Preferably, the air intake assembly is an axial flow fan.

[0012] Preferably, the inner wall of the drying oven and the inner wall of the door are both provided with a heat-insulating coating.

[0013] Preferably, the end of the air intake pipe furthest from the drying chamber is movably connected to an inspection door.

[0014] In summary, compared with the prior art, the present invention has the following beneficial technical effects:

[0017] (3) The present invention provides an enlarged section between the air inlet pipe and the drying chamber, which slows down the flow rate of hot air entering the drying chamber and makes the distribution more uniform, thereby further improving the drying effect;

[0018] (4) The present invention provides a heat-insulating coating on the inner wall of the drying oven and the lid, which reduces heat loss, improves energy utilization efficiency, and reduces production costs;

Detailed Implementation

[0025] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0026] Example 1:

[0027] like Figure 1 , 3 As shown, this utility model discloses a technical solution: a continuous bee pollen drying device, including a hollow drying box 1. The drying box 1 has a rectangular structure, and its bottom is fixed to the ground by bolts. A shelf 2 for holding bee pollen is placed inside the drying box 1. A feed inlet 3 is opened on the right side of the drying box 1. A cover door 4 is rotatably connected to the feed inlet 3 by a hinge. The inner side wall of the drying box 1 and the inner side wall of the cover door 4 are both provided with a heat insulation coating 14, which can reduce heat loss and improve energy utilization efficiency. In this application, a polyurethane foam heat insulation coating or an aerogel heat insulation coating is used.

[0028] The left side of the drying chamber 1 is connected to a horizontally arranged air inlet pipe 5. The top of the end of the air inlet pipe 5 away from the feed inlet 3 is connected to a circulating air pipe 6 through a flange. The circulating air pipe 6 has an L-shaped structure. The other end of the circulating air pipe 6 is connected to the top of the drying chamber 1 near the feed inlet 3, forming a gas circulation channel. The air inlet pipe 5 is provided with a heating component and a fan assembly 13 in sequence along the airflow direction. The heated air is introduced into the drying chamber 1 through the fan assembly 13 to dry the bee pollen.

[0029] Specifically, the shelf 2 includes multiple shelves 7 arranged from top to bottom. The shelves 7 are all welded to the shelf 2, and there is a gap between two adjacent shelves 7 for placing bee pollen. The shelves 7 are evenly provided with multiple through holes to facilitate the passage of hot air, so that the bee pollen can fully contact the hot air and achieve uniform drying.

[0030] Specifically, in this embodiment, the air intake component 13 adopts an axial flow fan, which has the characteristics of large air volume and low energy consumption, and can meet the airflow requirements of this device.

[0031] Specifically, the left end of the intake pipe 5 is connected to an inspection door 15 via a hinge, which facilitates the inspection of the operation of the heating components inside the intake pipe 5.

[0032] Example 2:

[0033] like Figure 1 , 2 As shown, this utility model discloses another technical solution, a continuous bee pollen drying device, which differs from embodiment 1 in that the right end of the air inlet pipe 5 is connected to an enlarged section 8 through a flange, and the enlarged section 8 is connected to the inside of the drying chamber 1. The enlarged section 8 has a hollow frustum-shaped structure, and its diameter gradually increases along the airflow direction. This structural design can slow down the flow rate of hot air entering the drying chamber 1, make the distribution more uniform, and further improve the drying effect.

[0034] Specifically, support frames 9 are installed on both sides of the bottom of the air intake pipe 5. The top of the support frame 9 is integrally provided with an arc-shaped plate 10 that is adapted to the outer wall of the air intake pipe 5. The support frame 9 and the air intake pipe 5 are fixed by the arc-shaped plate 10. The arc-shaped plate 10 is connected to the air intake pipe 5 by bolts to ensure the stability of the air intake pipe 5.

[0035] Example 3:

[0036] like Figure 3 , 4 As shown, this utility model discloses another technical solution, a continuous bee pollen drying device, which differs from embodiment 1 in that the above-mentioned heating components are provided in two sets along the length of the air inlet pipe 5, or more than two sets can be installed according to the actual situation. Each set of heating components includes a multi-layer filter screen plate 11 arranged along the length of the air inlet pipe 5. Electric heating rods 12 are welded or bolted between the multi-layer filter screen plates 11 in each set, and multiple electric heating rods 12 are evenly arranged circumferentially along the axis of the filter screen plate 11. Multiple sets of heating components can fully heat the air, increase the temperature of the hot air, and thus improve the drying efficiency. The diameter of the filter screen plate 11 is the same as the inner diameter of the air inlet pipe 5, and the filter screen plate 11 plays the role of supporting the electric heating rod 12 and filtering impurities, and can perform multiple filtrations on the air.

[0037] To facilitate the installation and maintenance of the heating and air intake components, an opening is provided at the bottom of the air intake pipe 5 corresponding to the heating and air intake components 13. Both the heating and air intake components 13 are fixedly mounted on the mounting plate with bolts. The mounting plate is adapted to the corresponding opening and can be detachably fixed to the corresponding opening with bolts.

[0038] The electric heating rod 12 and the axial flow fan in this application both adopt existing technology. Their specific structure or working principle can be derived by those skilled in the art through conventional means, and will not be described in detail here.

[0039] The continuous bee pollen drying device provided by this utility model is used by first opening the cover door 4, pulling out the shelf 2 from the drying chamber 1, and evenly placing the bee pollen to be dried on the tray. Small holes are opened on the bottom and sides of the tray. Then, the tray containing the bee pollen to be dried is placed on the multi-layer shelf 7. Close the cover door 4, start the electric heating rod 12 and the air intake assembly 13. The electric heating rod 12 heats the air in the air inlet pipe 5. The two sets of heating components make the air fully heated. The air intake assembly introduces the heated air into the drying chamber 1 through the air inlet pipe 5 and the expansion section 8. Hot air is evenly distributed inside the drying chamber 1, passes through the holes on the shelf 7, and comes into full contact with the bee pollen, removing the moisture from the bee pollen. Then, the rising hot air enters the air inlet pipe 5 through the circulating air pipe 6, is heated again, and enters the drying chamber 1, forming a circulation. During the drying process, the drying temperature and airflow speed can be controlled by adjusting the power of the electric heating rod 12 and the rotation speed of the fan assembly 13 according to the drying status of the bee pollen. After drying is completed, the electric heating rod 12 and the fan assembly 13 are turned off, the cover door 4 is opened, the shelf 2 is pulled out, and the dried bee pollen is taken out.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
