LPG Electric Heating Spray Dryer Maintenance And Maintenance For Hot Water

Application method of spray dryer:
The application method of spray dryer involves multiple steps. The following is a detailed operation process to ensure the normal operation of the equipment and the stable quality of the product:

1. Preliminary preparation
Inspection and installation:
Carefully check whether all parts of the spray dryer are intact. If damaged, they should be replaced in time.
Install each component correctly according to the equipment drawings or instructions to ensure tight connections and no leakage.
Install the liquid pipeline, air pipeline and exhaust pipeline, and ensure that the pipeline is unobstructed.
Safety protection:
Operators should always be equipped with personal protective equipment, such as gloves, protective glasses and masks, to prevent accidents.
Ensure that there are no flammable and explosive items around the equipment and maintain a good ventilation environment.

2. Start and preheat
Start the fan:
First start the fan and check whether the wind direction is correct and the air volume is stable.
Start the heater:
After the fan runs stably, start the heater and gradually increase the heating power to gradually increase the inlet air temperature to the set value.

3. Set parameters
Temperature setting:
According to the material characteristics and drying requirements, set the appropriate inlet air temperature and outlet air temperature.
Monitor temperature changes to ensure that the temperature is stable within the set range.

Other parameter settings:
Set the speed of the peristaltic pump or other feeding equipment as needed to control the feeding speed of the material.
Adjust the air pressure of the atomizer and the needle air pressure to ensure that the material can be sprayed evenly.

IV. Feeding and drying
Start feeding:
When the inlet and outlet air temperatures are stable within the set range, start feeding.
Adjust the peristaltic pump or other feeding equipment so that the material enters the spray dryer at a uniform speed.

Monitor the drying process:
Closely observe the material state and temperature changes during the drying process.
Adjust parameters such as feeding speed, spray pressure and air flow as needed to ensure the drying effect.

V. Shutdown and cleaning
Stop feeding:
Stop feeding when the material is used up or the predetermined drying time is reached.

Continue running:
Continue to run the fan and heater for a period of time to completely dry the remaining material.

Shut down the equipment:
After confirming that the material has been completely dried, turn off the compressor, heater and fan.
Wait for the equipment to cool naturally to room temperature.

Cleaning and maintenance:
Clean the feed pipe and the inside of the spray dryer to prevent material residue.
Maintain and maintain the equipment regularly, such as replacing filters, cleaning pipelines, etc.

VI. Precautions

Safe operation:
Never put your hands into the equipment, especially when the equipment is running.
Pay attention to safety measures such as fire prevention, explosion prevention and electric shock prevention.

Temperature control:
Ensure that the equipment operates within the appropriate temperature range to avoid burning or overheating of the product.

Material pretreatment:
Before feeding the material into the spray dryer, perform appropriate pretreatment, such as dissolving, mixing or filtering.

Regular maintenance:
Maintain and maintain the equipment regularly to extend the service life of the equipment and improve work efficiency.

Through the strict implementation of the above steps and precautions, the safe and efficient operation of the spray dryer can be ensured, and high-quality products can be produced.

Technical specification:

Note: The amount of water evaporation is related to the characteristics of the material and the hot air inlet and outlet temperatures. When the outlet temperature is 90℃, the water evaporation curve is shown in the figure above (for model selection reference). As the product is constantly updated, the relevant parameters will change without prior notice.

Ordering instructions:
