[0002] Chitosan is mainly found in the shells of marine arthropods such as shrimp and crab, the shells of insects, the cell membranes of fungi and algae, the shells and skeletons of mollusks, and the cell walls of higher plants. It is a product obtained by the deacetylation reaction of chitin and is one of the most widely found polysaccharides in nature. Chitosan has many unique properties, such as biodegradability, biocompatibility, non-toxicity, antibacterial properties, anticancer properties, lipid-lowering properties, and immune-enhancing properties. Therefore, it has a wide range of applications in many fields.

[0003] Traditional chitosan processing methods involve a lot of equipment, including washing, drying, hydrolysis, and precipitation. This requires frequent transfer of raw materials, which wastes a lot of manpower and resources.

Detailed Implementation

[0048] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0049] like Figures 1-9 As shown, the chitosan processing equipment provided in this embodiment includes a feeding and stirring mechanism 3 disposed above the reaction cylinder 2 and an electromagnetic stirring mechanism 7 corresponding to the feeding and stirring mechanism 3. A bottom plate driving mechanism 4 is disposed at the bottom of the reaction cylinder 2. The feeding and stirring mechanism 3 includes a stirring telescopic rod 301 and a discharge bucket 302. The discharge bucket 302 is provided with a plurality of evenly distributed water passage holes 305. A discharge bucket rotary motor 303 is fixedly disposed between the stirring telescopic rod 301 and the discharge bucket 302. The discharge bucket 302 is fixedly disposed at the output end of the discharge bucket rotary motor 303. The feeding bucket 302 is vertically slidably installed inside the reaction cylinder 2, which is a fixed structure. The feeding bucket 302 on the feeding and stirring mechanism 3 is rotatably installed inside the reaction cylinder 2 via the feeding bucket rotation motor 303, thus allowing the feeding bucket 302 to rotate and stir the raw materials inside. Simultaneously, the electromagnetic stirring mechanism 7 further stirs the raw materials inside the feeding bucket 302, achieving the stirring purpose through dual stirring. The specific method by which the electromagnetic stirring mechanism 7 stirs the raw materials inside the feeding bucket 302 is as follows:

[0050] The electromagnetic stirring mechanism 7 includes an electromagnet assembly 701 and a stirring component 702. The stirring component 702 is rotatably disposed inside the discharge tank 302. While the discharge tank 302 rotates, the stirring component 702 remains stable, meaning it does not rotate, thus stirring the raw materials inside the discharge tank 302. The electromagnet assembly 701 is fixedly disposed on the outer side of the reaction cylinder 2 and corresponds to the stirring component 702. The stirring component 702 is fixedly equipped with... The electromagnet assembly 701 includes an annular neodymium magnet 704 and an electromagnet box 709 and an iron core 707 fixedly installed inside the electromagnet box 709. A coil 708 is installed on the iron core 707. The annular neodymium magnet 704 is fixedly installed on the stirring assembly 702. When the coil 708 on the electromagnet assembly 701 is energized, the iron core 707 generates a magnetic field, which attracts the annular neodymium magnet 704 under the action of magnetic force. Therefore, the stirring assembly 702 can be fixed. During the rotation of the fixed feeding bucket 302, the raw materials inside the feeding bucket 302 can be stirred.

[0051] The bottom plate drive mechanism 4 includes a bottom plate drive motor 401 and a bottom plate support arm 402 disposed at the output end of the bottom plate drive motor 401. A cleaning and hydrolysis mechanism 5 and a drying mechanism 6 are fixedly disposed on the bottom plate support arm 402. The cleaning and hydrolysis mechanism 5 and the drying mechanism 6 are used to seal the bottom of the reaction cylinder 2. The cleaning and hydrolysis mechanism 5 and the drying mechanism 6 are disposed at the bottom of the reaction cylinder 2, which can perform cleaning, drying, hydrolysis and centrifugation reactions on the raw materials in the discharge tank 302. Specifically:

[0052] The cleaning and hydrolysis mechanism 5 includes a lower sealing plate 501 connected by a sealing telescopic rod 503. A rubber sealing ring 505 is fixedly installed on the upper side of the lower sealing plate 501, and a first heating ring 506 is fixedly installed on the upper side of the rubber sealing ring 505. The lower sealing plate 501 is extended into the bottom of the reaction cylinder 2 by the sealing telescopic rod 503 on the cleaning and hydrolysis mechanism 5, and the bottom of the reaction cylinder 2 is sealed by the lower sealing plate 501. The sealing telescopic rod 503 is fixedly installed on the bottom plate 404, and the lower sealing plate 501 is located at the output end of the sealing telescopic rod 503. Several buffer springs 504 are installed between the lower sealing plate 501 and the bottom plate 404. The buffer springs 504 provide a certain support for the lower sealing plate 501. To improve the sealing effect of the lower sealing plate 501 on the bottom of the reaction cylinder 2, the rubber sealing ring 505 on the lower sealing plate 501 is snapped onto the bottom of the reaction cylinder 2, which is also to improve the sealing performance of the bottom of the reaction cylinder 2. The rubber sealing ring 505 and the lower sealing plate 501 are provided with water inlet holes 507. A water inlet pipe 502 is fixedly installed inside the water inlet hole 507. The water inlet pipe 502 passes through the bottom plate 404 and is connected to a water pump. After the bottom of the reaction cylinder 2 is sealed by the cleaning and hydrolysis mechanism 5, an appropriate amount of water is injected into the inside of the reaction cylinder 2 through the water inlet pipe 502. Under the action of the feeding and stirring mechanism 3 and the electromagnetic stirring mechanism 7, the raw materials inside the discharge bucket 302 are cleaned. At the same time, the cleaning liquid is heated by the first heating ring 506 on the rubber sealing ring 505 to improve the cleaning effect.

[0053] Drying is achieved by draining water from the reaction cylinder 2 through the water supply pipe 502 on the cleaning hydrolysis mechanism 5. The drying mechanism 6 includes a fan support plate 601 and a drying fan 603 fixedly installed inside the fan support plate 601. Both the fan support plate 601 and the drying fan 603 are fixedly installed on the upper side of the base plate 404. The fan support plate 601 has a protective plate ventilation hole 602. The drying mechanism 6 is rotated to the bottom of the reaction cylinder 2. A second heating ring 604 is fixedly installed at the port of the fan support plate 601. The second heating ring 604 does not contact the drying fan 603. The drying fan 603 on the drying mechanism 6 accelerates the air flow rate inside the discharge bucket 302, thereby accelerating the evaporation of residual moisture. Under the action of the drying fan 603, the air temperature is increased, and the internal energy of the air is increased, so as to achieve the purpose of drying the raw materials inside the discharge bucket 302.

[0054] Hydrolysis is performed by rotating the cleaning and hydrolysis mechanism 5 to the bottom of the reaction cylinder 2 again. Hydrolysate is injected into the raw material inside the discharge tank 302 through the water supply pipe 502. At the same time, the rotation of the discharge tank rotary motor 303 on the feeding and stirring mechanism 3 can achieve centrifugation of the hydrolysate. Therefore, this device can sequentially perform cleaning, drying, hydrolysis and centrifugation operations on the raw material without the need to transfer the raw material. The structure is simple and the processing efficiency is greatly improved. Moreover, the raw material is always inside the discharge tank 302 and will not be oxidized due to transfer, thus improving the processing quality.

[0055] Furthermore, such as Figure 2 , Figure 5 as well as Figure 8 As shown, a processing support base 1 is fixedly connected to the reaction cylinder 2, and a stirring support arm 101 is fixedly connected to the processing support base 1. The feeding and stirring mechanism 3 is vertically arranged on the stirring support arm 101. Both the reaction cylinder 2 and the feeding and stirring mechanism 3 are fixed on the processing support base 1, which improves the overall structural strength of the device and thus improves the stability of the device.

[0056] The discharge bucket rotary motor 303 is fixedly installed at the output end of the stirring telescopic rod 301. The stirring telescopic rod 301 is used to push the discharge bucket rotary motor 303 downward. The discharge bucket rotary motor 303 is used to rotate the discharge bucket 302. Since the discharge bucket rotary motor 303 is installed at the output end of the stirring telescopic rod 301, the discharge bucket 302 can be extended into the interior of the reaction cylinder 2. The discharge bucket 302 rotates inside the reaction cylinder 2 to achieve the purpose of cleaning the raw materials.

[0057] Meanwhile, a threaded connector 310 is fixedly installed at the output end of the discharge bucket rotary motor 303. The upper end of the discharge bucket 302 is screwed into the threaded connector 310 through a thread. A feeding port 304 is opened on the upper end face of the discharge bucket 302. The upper part of the discharge bucket 302 is connected to the threaded connector 310 through a thread. Therefore, the discharge bucket 302 can be removed from the threaded connector 310 and raw materials can be put in through the feeding port 304, which improves the convenience and flexibility of use.

[0058] In addition, a sealing plate groove 308 is provided at the output end of the stirring telescopic rod 301, and an upper sealing plate 306 is slidably disposed on the sealing plate groove 308. The upper sealing plate 306 is used to seal the upper port of the reaction cylinder 2. The upper sealing plate 306 can seal the upper port of the reaction cylinder 2, thus allowing selective sealing of the upper port of the reaction cylinder 2 during cleaning, drying, and hydrolysis processes. This design is simple and improves the flexibility of use. A number of evenly distributed sealing plate clips 307 are fixedly installed on the upper sealing plate 306. A magnet block groove 201 corresponding to the sealing plate clips 307 is opened on the outer side of the reaction cylinder 2. A circular neodymium magnet 202 is fixedly installed inside the magnet block groove 201. A number of sealing plate clips 307 are installed on the upper sealing plate 306. The sealing plate clips 307 correspond to the circular neodymium magnets 202 on the magnet block groove 201. Therefore, the upper sealing plate 306 can be fixed to the upper port of the reaction cylinder 2. It is convenient and quick to use and achieves the purpose of sealing the upper port of the reaction cylinder 2.

[0059] Furthermore, such as Figure 5 and Figure 6 As shown, the stirring assembly 702 includes a rotating shaft 705. A discharge tank bottom plate 309 is fixedly installed at the bottom of the discharge tank 302. The rotating shaft 705 is rotatably mounted on the discharge tank bottom plate 309. Symmetrically distributed magnetic support arms 706 are fixedly installed on the rotating shaft 705. An annular magnetic groove 703 is opened on the outer side of the magnetic support arm 706. An annular neodymium magnet 704 is fixedly installed inside the annular magnetic groove 703. 6 is fixedly mounted on the rotating shaft 705. The annular rubidium magnet 704 rotates relative to the rotating shaft 705. The iron core 707 abuts against the outer side of the reaction cylinder 2 and corresponds to the annular rubidium magnet 704. A wire connector 710 is fixedly mounted on the upper side of the electromagnetic box 709. The conductor coil 708 is electrically connected to the conductor connector 710 and electrically connected to the external power source through the conductor connector 710. After the conductor coil 708 is energized, the iron core 707 generates magnetism and fixes the annular rubidium magnet 704 under the action of magnetic force.

[0060] Furthermore, such as Figure 2 and Figure 7As shown, the base plate support arm 402 has a V-shaped structure. A base plate 404 is fixedly mounted on the end of the base plate support arm 402 away from the base plate drive motor 401. The cleaning and hydrolysis mechanism 5 and the drying mechanism 6 are both fixedly mounted on the upper side of the base plate 404. The cleaning and hydrolysis mechanism 5 and the drying mechanism 6 are rotated by the base plate drive mechanism 4. The structure is simple, improving ease of use. The cleaning and hydrolysis mechanism 5 and the drying mechanism 6 are fixed to the base plate 404 on the base plate support arm 402, enhancing the stability of the cleaning and hydrolysis mechanism 5 and the drying mechanism 6. The bottom of the stirring support arm 101 is connected to the reaction cylinder fixing block 102. The reaction cylinder fixing block 102 is fixedly connected to the reaction cylinder 2 by welding. The reaction cylinder 2 is fixedly mounted on the stirring support arm 101 by the reaction cylinder fixing block 102, which improves the stability of the reaction cylinder 2. The bottom plate drive motor 401 is fixedly mounted on the processing support base 1 by the motor fixing plate 403, which ensures the stability of the bottom plate drive motor 401.

[0061] In addition, such as Figure 3 As shown, an electrical control box 8 is fixedly installed on one side of the stirring support arm 101. The feeding and stirring mechanism 3, the base plate driving mechanism 4, the cleaning and hydrolysis mechanism 5, the drying mechanism 6, and the electromagnetic stirring mechanism 7 are all connected to the electrical control box 8. The device can be directly controlled through the electrical control box 8, improving the ease of use. An infrared receiver 801 is fixedly installed on the processing support 1 below the base plate 404. An infrared transmitter 802 corresponding to the infrared receiver 801 is fixedly installed on the bottom side of the base plate 404. Both the infrared receiver 801 and the infrared transmitter 802 are connected to the electrical control box 8. An infrared transmitter 802 is fixedly installed at the bottom of the base plate 404. The infrared transmitter 802 corresponds to the infrared receiver 801, ensuring that the cleaning and hydrolysis mechanism 5 or the drying mechanism 6 rotates to the bottom of the reaction cylinder 2, improving the processing efficiency.

[0062] like Figures 1-9 As shown, the chitosan processing method provided in this embodiment includes the following steps:

[0063] Step 1: Raw material cleaning: Put the shrimp shells and crab shells into the inside of the feeding tank 302, and then start the bottom plate drive mechanism 4 to rotate the cleaning and hydrolysis mechanism 5 to the bottom of the reaction cylinder 2 and seal the inside of the reaction cylinder 2.

[0064] Start the stirring telescopic rod 301 to put the discharge bucket 302 into the inside of the reaction cylinder 2, and seal the upper port of the reaction cylinder 2 by the upper sealing plate 306;

[0065] A suitable amount of water is injected into the interior of the reaction cylinder 2 through the water supply pipe 502, and the discharge bucket rotation motor 303 is started to make the discharge bucket 302 rotate, thus cleaning the impurities on the raw materials.

[0066] Step 2: Raw material drying. After the raw material is cleaned, the water is discharged through the water pipe 502. Then, the drying mechanism 6 is rotated to the bottom of the reaction cylinder 2 through the bottom plate drive mechanism 4. The raw material is dried and impurities are removed by the drying fan 603 and the second heating coil 604 on the drying mechanism 6.

[0067] Step 3: Hydrolysis and sedimentation. After the raw materials are dried, the cleaning and hydrolysis mechanism 5 is rotated to the bottom of the reaction cylinder 2 again by the bottom plate drive mechanism 4. Water is injected and flocculant is added to hydrolyze the raw materials. The discharge bucket rotation motor 303 is started to make the discharge bucket 302 rotate at high speed and centrifugal sedimentation is performed.

[0068] Step 4: Drying and material collection. The precipitate is dried by passing it through the first heating coil 506, and then it can be processed further.
