Product Description Product IntroductionThe machine adopts a fully enclosed form, with all components made of stainless steel and equipped with a three-level purification device. The filtered air meets the requirement of 100000 levels. The cylinder and top are equipped with a cold wall device to ensure a wall temperature of less than 80 oC. The drying tower is equipped with an air brush scanning device. After being dried by this machine, the traditional Chinese medicine extract powder will not experience coking and deterioration, greatly increasing the powder collection rate (over 95%), and will not produce mixing and wall sticking phenomena.Working principleThe high-speed centrifugal spray device for Chinese herbal extracts is the application of centrifugal spray drying technology in the drying of specific materials. It is also a drying device that uses high-speed centrifugal atomizers to disperse materials into mist, fully contact with hot air, complete instant drying, and form powder products.

Technical specifications I. Basic Working Principle and Application:1. Basic Working PrincipleAir is filtered and heated, then enters the granulation chamber through the airflow distribution plate, causing the powder to suspend and form a fluidized state due to the combined action of airflow and gravity. Compressed air and binder enter the nozzle through their respective pipelines, and the binder is atomized into fine droplets at the nozzle, sprayed onto the fluidized powder to form granules. During this process, the left and right exhaust valves and cylinders periodically alternate to clean the powder adsorbed on the collection bag, allowing it to fall back into the granulation chamber, thus completing mixing, granulation, coating, and drying operations.1.1Top Spray: Combines fluidization and airflow transportation. The material in the material tank is pushed upward by the airflow from below, enters the expansion chamber, and is bonded by the slurry. Due to the increase in the diameter of the expansion chamber, the flow velocity decreases, and the fluidization state weakens. The material falls back into the material tank due to gravity, forming a reciprocating flow state from the material tank to the expansion chamber. Its characteristics are: reverse spray, long droplet travel.1.2 Bottom Spray: Combines fluidization and airflow transportation. Forms a central rising zone and a peripheral fluidization zone. The material in the central zone is pushed upward by the airflow, moves to the expansion chamber to form the rising zone, and falls into the peripheral zone when gravity overcomes the gradually weakening thrust, forming a reciprocating flow state from the center to the periphery, changing random fluidization into regular flow. Its characteristics are: co-directional spray, nozzle buried in the material, short droplet travel; high probability of granules passing through the spray mist; high density of granules in the spray area. 2. ApplicationThis equipment is suitable for mixing, granulating, coating and drying of powder materials. It is widely used in the fields of pharmacy, food, chemical industry, agriculture, forestry, etc. It is the granulating, drying and coating equipment widely used in the international market at present. Because of its different characteristics, it has its own focus in the application.2.1 Top spraying: granulation and drying Suitable for heat-sensitive materials, high efficiency and uniform drying; granulation: quick dissolution, low hardness, low bulk density, wide particle size distribution, fluffy and porous, good fluidity, easy to disintegrate and dissolve; coating: coloring, masking taste, moisture-proofing and improving appearance.2.2Bottom spraying: Coating Coating of polymerized materials with water solvent or organic solvent in ordinary film; less adhesion of materials, less evaporation of solvent, suitable for coating of organic solution, slow-release or controlled-release coating, enteric coating, coating of microfine particles, and wrapping dressing layer of active drugs.The composition of the equipment, the main structure and materials1.Equipment CompositionThis machine is an experimental model, and the structure is in the form of single machine structure.

Main performance characteristics1. Compact structure, beautiful appearance, easy to clean and maintain.2. Modularized structure form, a machine with a variety of functions.3. The fluidized bed of the air distribution sieve plate opening shape, distribution status, opening rate of the elaborate design, so that the air distribution has been greatly improved, prompting the material according to the needs of the process and full or orderly fluidization, improve the adaptability of the equipment to the material varieties.4. The host adopts the air top sealing mechanism to ensure the sealing effect, to avoid the failure to remove the adsorbed powder on the catch bag due to leakage, resulting in air duct obstruction, destroying the state of fluidization, which leads to an increase in the content of fine powder, or unable to complete the process operation (bed collapse phenomenon).5. The atomizer is easy to install and disassemble, with good atomization effect, which is conducive to the needs of the granulation process.6. Control system: reasonable configuration according to the needs of the system.
