Technical Field
[0001] This utility model belongs to the field of food drying technology, and in particular relates to an anhydrous glucose drying device. Background Technology Anhydrous glucose is a replacement product for monohydrate glucose. Compared with monohydrate glucose, it has the advantages of no pyrogen reaction, less impurity content, and higher purity. In the pharmaceutical industry, glucose injection and glucose sodium chloride injection made from anhydrous glucose can be used to supplement energy when food intake is reduced or unable to be consumed for certain reasons. It also has good medical effects on hypoxia, starvation ketosis, and dehydration.
[0002] Currently, fluidized bed drying is the main drying equipment used by anhydrous glucose production enterprises. However, there are some shortcomings in its use: 1. The material flow is discontinuous and poorly dispersed, resulting in insufficient contact between the material and hot air, making it difficult to ensure the uniformity of drying; 2. The residence time of the material in the drying zone is short, and the moisture cannot be fully evaporated, affecting the drying effect. Utility Model Content To solve the above-mentioned technical problems, this utility model provides an anhydrous glucose drying device, and the technical solution adopted is as follows: An anhydrous glucose drying device includes a cylinder, an upper cylinder cover at the upper end of the cylinder, a conical discharge cylinder at the lower end of the cylinder, a drive motor above the upper cylinder cover, a connecting rod connected to the drive motor below the upper cylinder cover, and multiple rotating plates arranged sequentially from top to bottom in the connecting rod. Each rotating plate has a discharge groove, and the discharge grooves in each rotating plate are alternately staggered at 90 degrees, 180 degrees, 270 degrees, and 360 degrees from top to bottom. On one side of the cylinder, a heating box is provided above each of the rotating plates except the bottommost one, and an air inlet box is provided above the bottommost rotating plate; on the other side of the cylinder, an exhaust box is provided corresponding to the heating box and the air inlet box; a connecting plate is provided on one side of the cylinder, and a baffle plate extending into the cylinder is provided on the inner side of the connecting plate corresponding to the top of each rotating plate.
[0003] Furthermore, one side of the exhaust box is provided with an exhaust pipe that connects all the exhaust boxes, and the exhaust pipe can centrally discharge the hot and humid exhaust gas collected in each exhaust box.
[0004] Furthermore, the heating chamber is equipped with a heating tube, and a temperature controller is located on the outside of the heating chamber. When the heating tube is powered on, it can generate hot air to provide a heat source for the drying process. Its power can be adjusted according to the actual drying needs.
[0005] Furthermore, an air inlet pipe is provided on one side of the heating box, connecting all the heating boxes and the air inlet box. The air inlet pipe can deliver the clean airflow processed by the air purification device to the heating box and the air inlet box respectively.
[0006] Furthermore, the number of rotating plates is 4-8, and the multiple rotating plates are arranged at equal intervals. The number of rotating plates can be flexibly selected according to the height of the cylinder and the drying efficiency requirements. The equidistant arrangement can make the residence time of the material in each section of the cylinder evenly distributed.
[0007] Furthermore, the heating box, air inlet box, and exhaust box are all equipped with arc-shaped filter screens at their openings, which can disperse airflow and capture large dust particles.
[0008] Furthermore, the cylinder has an opening for inserting a baffle plate.
[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, the material drop troughs of the rotary plate are distributed in an alternating staggered manner at a specific angle, so that the material can form a continuous and dispersed flow in the cylinder as it falls with the rotation of the rotary plate, prolonging the residence time of the material in the cylinder, allowing the material to fully contact the hot air, thereby improving the drying uniformity of the material.
[0010] 2. In this utility model, the air inlet box above the bottom rotating plate introduces purified room temperature airflow, which can cool down the high temperature material that is about to be discharged, avoid the material from "heating up and absorbing moisture" during storage, and ensure the stability of the finished product.
[0011] 3. In this utility model, the filter screen at the exhaust box opening can initially capture large glucose dust particles, and the bag filter connected after the exhaust pipe can deeply capture fine glucose powder. The collected powder can be dried and reused, which reduces material waste and dust emissions. Attached Figure Description

Detailed Implementation
[0014] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0015] As attached Figure 1-5 As shown.
[0016] An anhydrous glucose drying device includes a cylinder 1, an upper cylinder cover 2 at the upper end of the cylinder 1, a conical discharge cylinder 3 at the lower end of the cylinder 1, a drive motor 22 above the upper cylinder cover 2, and a connecting rod 21 connected to the drive motor 22 below the upper cylinder cover 2. Multiple rotating plates 23 are arranged sequentially from top to bottom in the connecting rod 21, and the multiple rotating plates 23 are arranged at equal intervals.
[0017] The rotary plate 23 is provided with a material drop chute 24. From top to bottom, the material drop chute 24 in each rotary plate 23 is alternately staggered at 90 degrees, 180 degrees, 270 degrees and 360 degrees, respectively, to ensure that the material can form a continuous and dispersed flow in the cylinder 1 during the process of the material falling with the rotary plate 23, prolonging the residence time of the material in the cylinder and improving the drying uniformity.
[0018] The number of rotating plates 23 is 4-8. The more rotating plates 23 are set, the longer the material stays in the cylinder 1.
[0019] On one side of the cylinder 1, except for the bottommost rotating plate 23, a heating box 5 is provided above each of the other rotating plates 23. An air inlet box 6 is provided above the bottommost rotating plate 23. An air inlet pipe 4 is provided on one side to connect the heating box 5 and the air inlet box 6. The air inlet box 6 has the same structure as the heating box 5, except that a heating pipe 51 is provided inside the heating box 5, and a temperature controller is provided on the outside of the heating box 5.
[0020] An exhaust box 71 is provided on the other side of the cylinder 1, corresponding to the heating box 5 and the air inlet box 6, and an exhaust pipe 7 is provided on one side to connect all the exhaust boxes 71.
[0021] Arc-shaped filter screens 9 are provided at the openings of the heating box 5, the air inlet box 6, and the exhaust box 71.
[0022] A connecting plate 8 is provided on one side of the cylinder 1. A baffle 81 is provided on the inner side of the connecting plate 8 and above each rotating plate 23. An opening is provided in the cylinder 1 for inserting the baffle 81.
[0023] The process of using this device is as follows: the anhydrous glucose raw material to be dried is put into the cylinder 1 through the feed pipe 25 at the top of the upper cylinder cover 2, and the raw material naturally accumulates on the surface of the uppermost rotating plate 23.
[0024] Then the drive motor 22 is started, and the connecting rod 21 drives the multi-layer rotating plate 23 to rotate at a constant speed. When the rotating plate 23 rotates, the baffle 81 cooperates with the rotating plate 23 to form an "interception-discharge" mechanism. When the material moves in a circle with the rotating plate 23, the baffle 81 blocks the tendency of horizontal splashing, forcing the material to fall from the discharge chute 24 on the rotating plate 23.
[0025] Because the material drop troughs of each layer of rotary plates 23 are alternately staggered at 90°, 180°, 270° and 360°, the material will be dispersed and fall to the lower rotary plates 23 one by one, which not only prevents the material from escaping, but also allows the material to form a "spiral dispersion flow" in the cylinder 1, maximizing the extension of the drying residence time.
[0026] Inside the heating chamber 5, the heating tube 51 is powered on to generate hot air. The airflow is cut and dispersed into multiple uniform airflows by the arc-shaped filter screen 9 at the chamber opening. The airflow is sent into the cylinder 1 through the air inlet pipe 4. The hot air comes into full contact with the material on the rotating plate 23, which can quickly remove the moisture from the material and realize the drying process.
[0027] At this point, the material is dry but the temperature is high. The air inlet box 6 above the bottom rotating plate 23 will introduce purified room temperature airflow. After the airflow is dispersed by the filter screen 9, it will cool down the high temperature material that is about to be discharged, so as to prevent the material from "heating up and absorbing moisture" during storage and ensure the stability of the finished product.
[0028] During the above process, the gas introduced through the air inlet pipe 4 needs to be pre-treated by an air purification device to ensure that the airflow entering the heating box 5 and the air inlet box 6 is clean and free of impurities, so as to avoid contaminating the anhydrous glucose.
[0029] The hot and humid exhaust gas generated during material drying is first collected by the exhaust box 71 on the other side of the cylinder 1. The filter screen 9 at the opening of the exhaust box 71 can initially capture large glucose dust particles. The exhaust pipe 7 can then be connected to a bag filter, which uses the micropores of the bag to deeply capture fine glucose powder. The collected powder can be dried and reused, which reduces material waste and dust emissions.
[0030] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
