Description

Technical Field

[0001] This utility model relates to the field of sodium alginate processing technology, and more specifically, to a drying device for processing sodium alginate products. Background Technology

[0002] Sodium alginate is a byproduct of the extraction of iodine and mannitol from brown algae such as kelp or Sargassum. It is a natural polysaccharide that possesses the stability, solubility, viscosity, and safety required for pharmaceutical excipients. Sodium alginate has been widely used in the food industry and the pharmaceutical field.

[0003] Currently, after sodium alginate production is completed, a drying process is required. Drying reduces the moisture content of sodium alginate, preventing it from absorbing moisture, clumping, or degrading. After drying, it can be stored in a sealed container. Existing methods for drying sodium alginate products generally involve vacuum drying. Vacuum drying relies solely on tray heat conduction, resulting in a large temperature difference between the inside and surface of the material, leading to uneven heating and generally low drying efficiency. Utility Model Content

[0006] Furthermore, the horizontal pushing component includes a telescopic cylinder, a U-shaped platform, and a slide rail.

A hot air blower and a second servo gear transmission assembly are fixed on the U-shaped platform, and the drying tube is rotatably connected to the U-shaped platform. The slide rails are symmetrically arranged on the base plate, and the slide rails slide in contact with both ends of the U-shaped platform.

[0007] Furthermore, the first servo gear transmission assembly includes a first servo motor, a first main gear, and a first auxiliary gear.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: like Figures 1 to 3 As shown, a drying device for processing sodium alginate products includes a base plate 1, a mounting frame 2, a first servo gear transmission assembly 3, a ring 4, a roller 5, a spiral guide plate 6, a feed hopper 7, a horizontal pushing assembly 8, a hot air blower 9, a second servo gear transmission assembly 10, a drying tube 11, a rotary joint 12, a nozzle 13, and an arc-shaped blade 14. Mounting bracket 2 is fixed on base plate 1, and mounting bracket 2 is provided with first servo gear transmission assembly 3 and ring 4; The open-end roller 5 is rotatably connected to the ring 4 through bearings, and the roller 5 is connected to the first servo gear transmission assembly 3. A spiral guide plate 6 is wound and welded along the length of the inner wall of the roller 5. The feed hopper 7 is fixed on the base plate 1, and the end of the feed hopper 7 is connected to one end of the roller 5 and is distributed at intervals with the spiral guide plate 6. The horizontal pushing component 8 is mounted on the base plate 1, and a hot air blower 9 and a second servo gear transmission component 10 are fixed on the horizontal pushing component 8. The hot air blower 9 is based on existing technology and will not be improved. Its structural composition and operating principle are as follows: composition: 1. Heating element (heating tube / resistance wire); 2. High-temperature resistant centrifugal fan; Working principle: Current passes through the resistance wire to generate heat → a fan blows air through the heating element → hot air is output (the outlet air temperature is adjustable).

[0016] The drying tube 11, which is open at one end, is rotatably mounted on the horizontal pushing component 8. The drying tube 11 is coaxial with the drum 5 and connected to the second servo gear transmission component 10. (Specifically, the rotation direction of the drying tube 11 is opposite to that of the drum 5. The opposite rotation of the two causes the nozzle 13 on the drying tube 11 to be opposed to the flow direction of the sodium alginate product. The hot air directly penetrates the material layer, thereby improving the utilization rate of hot air, reducing the drying blind zone, and accelerating the evaporation of moisture.) One end of the rotary joint 12 is connected to the open end of the drying tube 11, and the other end of the rotary joint 12 is connected to the hot air blower 9; Several nozzles 13 are connected to the inside of the drying tube 11; Several arc-shaped blades 14, spaced apart from the spiral guide plate 6, are arranged on the drying tube 11, and the arc-shaped blades 14 and the nozzles 13 are staggered. Further refinements of the above embodiments, such as... Figure 1 As shown, a collection box 15 is placed on the base plate 1 below the end of the roller 5.

[0017] Specific implementation of this utility model solution, such as Figure 1 As shown, the horizontal pushing component 8 includes a telescopic cylinder 81, a U-shaped platform 82, and a slide rail 83. Telescopic cylinder 81 is fixed on base plate 1, and telescopic cylinder 81 is connected to U-shaped platform 82. Hot air blower 9 and second servo gear transmission assembly 10 are fixed on U-shaped platform 82. Drying pipe 11 is rotatably connected to U-shaped platform 82. The slide rails 83 are symmetrically arranged on the base plate 1, and the slide rails 83 slide in contact with the two ends of the U-shaped platform 82.

[0018] Specific implementation of this utility model solution, such as Figure 1 As shown, the first servo gear transmission assembly 3 includes a first servo motor, a first main gear, and a first auxiliary gear (all of the above structures are shown in the figure but are not specifically labeled). The first servo motor is fixed on the mounting bracket 2 and connected to the first main gear; The first auxiliary gear is fixed on the outer wall of the drum 5, and the first auxiliary gear meshes with the first main gear.

[0019] Specific implementation of this utility model solution, such as Figure 1 As shown, the second servo gear transmission assembly 10 includes a second servo motor, a second main gear, and a second auxiliary gear (all of the above structures are shown in the figure but are not specifically labeled). The second servo motor is fixed on the U-shaped platform 82 and is connected to the second main gear; The second auxiliary gear is fixed on the outer wall of the drying tube 11, and the second auxiliary gear meshes with the second main gear.

[0020] To reduce the probability of sodium alginate product entering the drying tube 11 from the nozzle 13, the above embodiment is further optimized by installing a filter screen inside the nozzle 13, which is not shown in the figure.

[0021] To measure the drying temperature in real time and avoid overheating or underheating, further optimizations to the above embodiments are possible, such as... Figure 1 and Figure 3 As shown, an infrared temperature sensor 16 is installed on the drying tube 11, facing the inner wall of the drum 5 (this is existing technology and will not be improved), and the infrared temperature sensor 16 is far away from the spray path of the nozzle 13; The principle by which the infrared temperature sensor 16 detects the temperature of the inner wall of the drum 5 that blows hot air in real time is mainly based on non-contact infrared radiation measurement technology, which can be divided into the following three core steps: 1. Infrared radiation acquisition The inner wall of roller 5 continuously emits infrared radiation (wavelength is temperature-dependent) due to high temperature. The sensor focuses this radiation energy through an optical system (lens or mirror). 2. Signal Conversion and Processing The focused infrared energy is converted into an electrical signal by a thermopile or pyroelectric sensor, and the signal strength is proportional to the radiated energy. The microprocessor further calculates the actual temperature value based on parameters such as emissivity and ambient temperature. 3. Real-time output and adaptability The processed temperature data is transmitted to the controller via the interface, and the controller then controls the hot air blower 9 to work intermittently to avoid the temperature being too high or too low.

[0022] It should be noted that the first servo motor, telescopic cylinder 81, hot air blower 9, second servo motor, and infrared temperature sensor 16 are all electrically connected to the controller, which is shown in the figure without a number.

[0023] The working process of this utility model is as follows: Before adding sodium alginate, the controller first controls the operation of the first servo motor, which works in conjunction with the first main gear and the first auxiliary gear to drive the drum 5 to rotate at a constant speed. At the same time, the controller controls the operation of the telescopic cylinder 81, which allows the drying tube 11 to enter the drum 5 (the entry length of the drying tube 11 is preset and the distance from the feed end of the drum 5 is 15-20CM). After the drying tube 11 has entered, the controller controls the operation of the second servo motor and the hot air blower 9 to achieve the uniform rotation of the drying tube 11 and blow warm air into multiple areas inside the drum 5. Then, the sodium alginate is added into the drum 5 through the feed hopper 7. After the sodium alginate is added, it can move along the end of the drum 5 under the action of the spiral guide plate 6. During the rotation of drum 5, the sodium alginate is constantly tumbled. At this time, the arc-shaped blades 14 can intermittently contact the solid sodium alginate product to break up large pieces of sodium alginate. Breaking them up allows the interior of the large pieces of sodium alginate to be effectively dried as well (smaller pieces of sodium alginate can be lifted a second time for even better drying). As the drying process continues, the infrared temperature sensor 16 can perform real-time non-contact temperature monitoring inside drum 5 to prevent overheating that could cause denaturation or deactivation of the sodium alginate, while also preventing insufficient temperature from affecting drying efficiency. Combined with the intermittent operation of the hot air blower 9, the drying effect can be further improved. Finally, the dried sodium alginate flows into the collection box 15 for storage. After a batch of sodium alginate is dried, the controller controls the telescopic cylinder 81 to retract, which moves the drying tube 11 to the outside of the drum 5. Then, the arc blade 14, nozzle 13, filter screen and the inside of the drum 5 are cleaned in sequence. After cleaning, the next round of sodium alginate solid drying process can begin.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.

Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
