Factors Influencing Filling Accuracy Performance
Formulation Properties and Viscosity Control
The accuracy of a liquid capsule filling machine is significantly influenced by the physical and chemical properties of the liquid formulation being processed. Viscosity plays a crucial role in determining how accurately the machine can dispense liquid into capsules, as higher viscosity formulations require different pumping pressures and timing parameters to achieve optimal accuracy. The liquid capsule filling machine must be equipped with variable speed pumps and adjustable pressure systems that can accommodate formulations ranging from low-viscosity solutions to thick suspensions and microemulsions. Temperature control becomes critical when processing temperature-sensitive formulations, as viscosity changes can directly impact filling accuracy. Advanced machines incorporate heated reservoirs and temperature-controlled filling heads that maintain consistent formulation properties throughout the production process. The NYF-300's versatility in handling solutions, suspensions, and microemulsions demonstrates its sophisticated control systems that automatically adjust parameters based on formulation characteristics. Proper formulation preparation, including adequate mixing and degassing procedures, is essential for maintaining consistent accuracy levels throughout production runs.
Machine Calibration and Maintenance Protocols
Regular calibration and maintenance are fundamental to maintaining the accuracy performance of liquid capsule filling machines over their operational lifetime.
