The water chestnut sugar coating machine is widely used in the pharmaceutical, food, and chemical industries for sugar coating, film coating, and other treatments on tablets, pills, or granules. Proper operation and maintenance of equipment are crucial for ensuring product quality and extending equipment lifespan. The following are key precautions when using this device:
1、 Preparation before operation
1. Equipment inspection: Before starting, a comprehensive inspection of the appearance of the equipment is required to confirm that all components are intact and undamaged. If any damage is found, it should be reported for repair in a timely manner. Focus on checking the power cord, plug, and voltage stability to ensure compliance with equipment requirements. At the same time, it is necessary to verify that the compressed air pressure is stable and the pipeline is leak free to ensure the normal operation of the spray system.
2. Cleaning and lubrication: Thoroughly clean the interior of the coating pot to avoid foreign matter residue affecting product purity; Check the lubrication parts such as the gearbox and bearings to ensure good lubrication and reduce wear.
3. Auxiliary material verification: Check the quality of coating auxiliary materials, such as syrup or film solution, to ensure that there are no impurities or deterioration issues, and to prevent production interruption caused by unqualified auxiliary materials.
2、 Operation process specification
1. Safety protection: It is strictly prohibited to remove electrical or belt protective covers during equipment operation to prevent mechanical injury or electric shock accidents. Operators need to be familiar with the location of the emergency stop button to ensure quick response to abnormal situations.
2. Parameter control: Accurate adjustment is required when setting the temperature to avoid affecting the quality of the coating by being too high or too low. For example, during the film spraying stage, the heating inlet temperature should be kept above 80 ℃, and the main engine speed should be gradually adjusted to ensure that the material rolls evenly. The spray system needs to be coordinated with a peristaltic pump and compressed air to ensure that the coating liquid is evenly covered in a mist.
3. Material monitoring: During the drying process, it is necessary to closely observe the surface of the tablets to prevent water stains or bubbles, and ensure that the coating layer is firm and smooth.
3、 Maintenance and upkeep
1. Regular inspection: Key components such as worm gears, worm gears, and bearings need to be inspected every three months to evaluate their rotational flexibility and wear level, and to promptly repair or replace damaged parts. The lubricating oil of the gearbox should be replaced regularly, generally not exceeding six months, to maintain efficient operation of the equipment.
2. Cleaning and rust prevention: Thoroughly clean the coating pot after each use, and apply oil on the surface to prevent oxidation before long-term use to avoid corrosion affecting the next use. Keep the work environment clean and reduce dust from entering the interior of the equipment.
3. System maintenance: Regularly check the power grounding device to ensure that the grounding resistance value meets safety standards (≤ 4 Ω) and prevent accidents caused by static electricity accumulation.
4、 Operator requirements
1. Training and assessment: Operators need to receive equipment performance, regulations, and safety training to ensure proficiency in operating skills. Regular assessments are conducted to strengthen safety awareness and reduce the risk of human error.
2. Standardized operation: It is strictly prohibited to adjust equipment parameters arbitrarily during operation. In case of any abnormalities, the machine should be stopped immediately and reported to avoid expanding the fault.
5、 Environment and subsequent processing
1. Environmental management: Maintain workshop cleanliness and dryness to avoid moisture or impurities affecting equipment performance. After the operation is completed, the site should be cleared according to the regulations, records should be filled out, and the quality inspection personnel should be notified for acceptance.
2. Product processing: The coated material should be moved to a drying room for cooling to avoid moisture; Hang equipment status signs after site clearance to ensure compliance with production processes.
By following the above precautions, the operating efficiency and product quality of the water chestnut sugar coating machine can be improved, while ensuring operational safety.
