1. Color Touch Screen: The liquid crystal display (LCD) features one - button power on/off functionality, ensuring convenient operation.
2. Spray Gun: Constructed from stainless steel, it is equipped with a concentric spray head and allows for vertical movement.
3. Spray Drying Chamber: Facilitates the thorough contact between atomized materials and gas, enabling the evaporation of solvents in the materials and the formation of fine powder particles through drying.
4. Cyclone Separation: The entire spray drying process offers real-time visual monitoring for immediate troubleshooting, with easy disassembly for thorough cleaning. 
5. Collection Bottle: The dried powder product exhibits a relatively uniform particle size distribution. Specifically, more than 95% of the dry powder falls within the same particle - size range.
6. The green button serves as the one - button start switch, while the red button functions as the emergency stop button.

Environmental Conditions
1. It is advisable to maintain the ambient temperature within the range of 10°C to 30°C. The relative humidity should be kept between 30% and 70%. The equipment should be avoided from being placed in environments with extreme temperatures or high humidity levels.
2. The equipment should be positioned in a well - ventilated location to ensure efficient heat dissipation and avoid overheating issues.
3. The equipment must be placed on a solid and level surface to prevent vibration and displacement, which could potentially affect its operation.

Precautions
1. Operators should be familiar with the structure, performance, operation methods and safety precautions of the equipment.
2. Ensure that the power cord is firmly and reliably connected. Conduct a thorough inspection of all components of the equipment to verify their integrity and ensure that the equipment is in optimal working condition. Check that all components are correctly installed, tightly connected, and free from any leaks. Additionally, make certain that all pipelines are unobstructed to guarantee smooth operation.
3. Initially, start the fan and carefully check whether the air flow direction is correct and the air volume is stable. Subsequently, start the heater and gradually increase the heating power, allowing the inlet air temperature to rise gradually. This step - by - step approach helps to maintain stable operating conditions.
4. Based on the specific characteristics of the material and the requirements of the drying process, set appropriate inlet and outlet air temperatures. Continuously monitor the temperature variations to ensure that the temperatures remain within the preset range. Precise temperature control is crucial for achieving consistent drying results.
5. Once the inlet and outlet air temperatures have stabilized within the set range, initiate the feeding process. Adjust the peristaltic pump or other feeding devices to ensure that the material enters the spray dryer at a uniform rate. This uniform feeding is vital for the quality of the dried product.
6. When the material supply is exhausted or the predetermined drying time has elapsed, stop the feeding operation. Continue to run the fan and heater for a certain period to ensure the complete drying of any remaining material. After that, turn off the peristaltic pump or other feeding equipment and thoroughly clean the feeding pipeline to prevent material accumulation and potential blockages. Once it is confirmed that the material is fully dried, shut down the compressor and heater, and allow the equipment to cool down to room temperature naturally. This proper shutdown procedure helps to extend the lifespan of the equipment.
7. After the equipment has cooled down, remove the collection bottle and clean it thoroughly. Conduct a detailed inspection of the product quality. In the event of any abnormalities, promptly analyze the root causes and implement corresponding corrective measures. This quality control step is essential for ensuring the reliability of the production process.
8.In the closed operation process, if spraying organic solvents (e.g. ethanol, xylene, etc.), the oxygen concentration must be controlled at less than 5%, which can be achieved by re-introducing nitrogen or re-opening the machine to make the oxygen concentration reach the required value, otherwise the organic solvents will have the danger of combustion and explosion.
9. During the operation of the spray dryer or for a short period after it has been shut down, the surface temperature of components such as the bag filter, cyclone separator, air ducts, atomizer, exhaust fan, and observation window remains relatively high. To avoid the risk of burns, it is strictly prohibited to touch these components with bare hands. This safety measure is necessary to protect the operators from potential injuries.
