[0002] Carboxymethyl chitosan is an important chitosan derivative with wide applications in many fields such as food, medicine, and cosmetics. Drying is a key step in the production of carboxymethyl chitosan, its purpose being to remove moisture from the chitosan to improve product stability and shelf life.

[0003] Existing carboxymethyl chitosan drying equipment has several shortcomings. For example, traditional drying equipment mostly uses hot air to directly blow on the material, which is inefficient and prone to uneven heating, potentially leading to quality degradation in some areas due to overheating. Furthermore, during the drying process, the material tends to accumulate, hindering the rapid release of internal moisture and further prolonging the drying time, increasing production costs. In addition, existing equipment lacks precise control over the humidity and temperature of the drying environment, which also affects the final quality of the carboxymethyl chitosan. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for the production of carboxymethyl chitosan to solve the problems mentioned in the background art, such as low drying efficiency, uneven heating of materials, long drying time, and inaccurate control of the drying environment in existing carboxymethyl chitosan drying devices.

[0005] The technical solution provided by this utility model is as follows: A drying device for the production of carboxymethyl chitosan includes a drying chamber. An air supply system is provided at the bottom of the drying chamber. The air supply system includes an air inlet pipe, one end of which is connected to the bottom of the drying chamber. An air filter, a hot air blower, and a flow regulating valve are sequentially arranged on the air inlet pipe. A rotating cage is rotatably arranged inside the drying chamber. A sealing cover is provided at the outlet of the rotating cage, and the sealing cover is rotatably connected to the drying chamber. Several ventilation holes are evenly distributed on the surface of the rotating cage. A heating wire is provided on the inner wall of the rotating cage. A humidity sensor and a temperature sensor are provided inside the drying chamber. An exhaust system is provided at the top of the drying chamber. The exhaust system includes an exhaust pipe, one end of which is connected to the top of the drying chamber. An exhaust fan, an air purifier, and a flow regulating valve are sequentially arranged on the exhaust pipe.

[0006] Based on the above technical solution, the present invention can be further improved as follows:

[0007] Furthermore, the drying chamber is equipped with a controller, which is electrically connected to the air filter, hot air blower, flow regulating valve one, heating wire, humidity sensor, temperature sensor, exhaust fan, air purifier and flow regulating valve two.

[0008] Furthermore, the rotating cage is equipped with a mesh bag inside, which is used to hold carboxymethyl chitosan.

[0009] Furthermore, the mesh count of the mesh bag is 350-450 mesh.

[0010] Furthermore, the tray body is made of metal.

[0011] Furthermore, the vent holes are arranged in a matrix, and the diameter of the vent holes is 1-3mm.

[0012] Furthermore, the bottom of the drying chamber is provided with support legs, and the bottom of the support legs is provided with shock-absorbing pads.

[0013] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0014] 1. This utility model achieves dual heating of materials (contact conduction + hot air convection) by combining a rotating drum with built-in heating wire and vent holes. With the precise air delivery of the hot air blower and flow regulating valve, the drying efficiency is significantly improved, ensuring that carboxymethyl chitosan is heated evenly and avoiding local overheating or clumping.

[0015] 2. This utility model uses a humidity sensor, a temperature sensor, and a controller to monitor and automatically adjust the heating wire power, hot air flow rate, and exhaust volume in real time to maintain the optimal drying environment, ensure the consistency of product moisture content, avoid molecular structure damage caused by excessive drying, and the hot air blower and exhaust fan work together to remove moisture in time, reduce the risk of internal pressure in the chamber, and improve production safety.

[0016] 3. The drying equipment of this utility model, through the air supply system, rotating drum, exhaust system and automatic control, can achieve efficient and uniform drying of carboxymethyl chitosan, ensuring product quality; at the same time, it has good environmental performance, reducing pollution to the environment; the equipment is stable in operation and easy to operate, which can effectively improve production efficiency and reduce production costs, and has high practical value and economic benefits.

[0019] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0020] like Figure 1As shown, a drying device for the production of carboxymethyl chitosan includes a drying chamber 1, an air supply system, a rotating drum 6, an exhaust system, and a controller 11. The drying chamber 1 is the main body of the entire device, providing a relatively enclosed space for the drying process. The bottom of the drying chamber 1 is provided with support legs 12, and the bottom of the support legs 12 is provided with shock-absorbing pads 13, which can stabilize the device and reduce the vibration and noise generated during the operation of the device. The drying chamber 1 is equipped with a humidity sensor and a temperature sensor for real-time monitoring of the humidity and temperature inside the chamber. The bottom of the drying chamber 1 is equipped with an air inlet system, which includes an air inlet pipe 2. One end of the air inlet pipe 2 is connected to the bottom of the drying chamber 1. An air filter 3, a hot air blower 4, and a flow regulating valve 5 are sequentially installed on the air inlet pipe 2. The air filter 3 can purify the air entering the drying chamber 1 and prevent impurities from contaminating the carboxymethyl chitosan. The hot air blower 4 is used to heat the air and provide heat for the drying process. The flow regulating valve 5 can adjust the airflow, thereby controlling the temperature and airflow speed inside the drying chamber 1. The drying chamber 1 contains a rotating drum 6, which is made of metal and has good thermal conductivity and strength. The outlet of the rotating drum 6 is equipped with a sealing cover 61, which is rotatably connected to the drying chamber 1 for easy loading and unloading of materials. The surface of the rotating drum 6 is evenly provided with several ventilation holes 62, which are arranged in a matrix and have a diameter of 1-3mm. These ventilation holes 62 can ensure that hot air passes through the rotating drum 6 and makes full contact with the materials, while preventing materials from leaking out of the ventilation holes 62. The inner wall of the rotating drum 6 is provided with heating wires (not shown in the figure) to assist heating and improve drying efficiency. The rotating drum 6 is provided with a mesh bag inside, which is used to hold carboxymethyl chitosan. The mesh of the mesh bag is 350-450 mesh, which can both hold the materials and allow the hot air to make better contact with the materials. The top of the drying chamber 1 is equipped with an exhaust system, which includes an exhaust pipe 7. One end of the exhaust pipe 7 is connected to the top of the drying chamber 1. An exhaust fan 8, an air purifier 9, and a flow regulating valve 10 are sequentially mounted on the exhaust pipe 7. The exhaust fan 8 can promptly extract humid air from the drying chamber 1, accelerating the drying process. The air purifier 9 purifies the exhaust air, reducing environmental pollution. The flow regulating valve 10 adjusts the exhaust flow rate, working in conjunction with the air supply system to control the airflow and humidity within the drying chamber 1. A controller 11 is installed on the drying chamber 1. The controller 11 is electrically connected to the air filter 3, hot air blower 4, flow regulating valve 5, heating wire, humidity sensor, temperature sensor, exhaust fan 8, air purifier 9, and flow regulating valve 10. The controller 11 can automatically adjust the operating status of each component based on data from the humidity and temperature sensors, achieving automated control of the drying process.

[0021] The working process of this utility model is as follows: First, open the sealing cover 61 of the rotating drum 6, place the mesh bag containing carboxymethyl chitosan into the rotating drum 6, and then close the sealing cover 61; then start the controller 11, the air filter 3 starts working, purifying the air entering the air inlet pipe 2, the hot air blower 4 heats the air, and the air inlet flow is adjusted by the flow regulating valve 5 to allow the hot air to enter the drying chamber 1. At the same time, the rotating drum 6 starts to rotate, and the heating wire is energized to heat and assist drying; the hot air enters the interior of the rotating drum 6 through the vent holes 62 on the surface of the rotating drum 6, making full contact with the carboxymethyl chitosan and removing moisture from the material; the humidity sensor and temperature sensor monitor the humidity and temperature inside the drying chamber 1 in real time and transmit the data to the controller 11; the controller 11... According to the preset drying parameters, the power of the hot air blower 4, the opening of the flow regulating valve 5, the heating intensity of the heating wire, and the rotation speed of the drum 6 are automatically adjusted to ensure that the drying process is carried out under optimal conditions. The exhaust fan 8 draws out the humid air in the drying chamber 1, which is then purified by the air purifier 9 and discharged. The flow regulating valve 10 can adjust the exhaust flow rate to maintain appropriate air pressure and airflow speed in the drying chamber 1. When the humidity sensor detects that the humidity in the drying chamber 1 has reached the preset value, the controller 11 issues a command to stop the operation of the hot air blower 4, the heating wire, and the exhaust fan 8, and close the flow regulating valve 5 and the flow regulating valve 10. After the drum 6 stops rotating, the sealing cover 61 is opened and the dried carboxymethyl chitosan is taken out.
