In the quantitative packaging of particle products (such as food, medicine, and chemical raw materials), material fluidity is one of the core factors affecting the volume measurement accuracy of particle packaging machines. This article combines common industry problems to briefly analyze the challenges and coping strategies brought by fluidity differences.
Fluidity differences: measurement deviation from theory to practice
The shape of particle materials (spherical, flake, irregular powder), surface friction coefficient, and humidity directly affect the uniformity of their flow in the packaging machine silo and metering cavity. For example:
·High-fluidity particles (such as dry spherical materials): It is easy to fall rapidly due to gravity, resulting in overload of metering cavity filling or "early drop" caused by equipment vibration, resulting in single package weight fluctuations.
·Low-fluidity particles (such as wet powder or flake materials): It is easy to form bridges and voids in the silo, resulting in insufficient filling of the metering cavity and even causing equipment jams.
The above problems will significantly reduce the stability of the granule packaging machine, especially in scenarios with small doses and high precision requirements (such as health care product packaging), which may cause customer complaints and waste of raw materials.
Technical optimization: Dynamic adaptation to fluidity fluctuations
In order to cope with fluidity differences, our factory has systematically upgraded the volumetric metering module of the granule packaging machine:
.Adaptive adjustment system: By real-time monitoring of material level and flow resistance, dynamically adjust the screw speed or vibration feeding frequency to balance the filling speed and accuracy.
.Modular cavity design: Provide metering cavities and agitator accessories of various specifications to adapt to materials with different particle sizes and friction coefficients.
.Surface treatment process: Use special coating or polishing technology on the contact surface to reduce particle adhesion and improve fluidity consistency.
Case inspiration: From "error correction" to efficiency improvement
When a nut roasting company used our granule packaging machine to package mixed dried fruits, the weight deviation of a single package was caused by the difference in fluidity between dried fruits and nuts. By upgrading the metering module with multi-level vibration compensation, the equipment can automatically identify changes in fluidity and fine-tune parameters, ultimately raising the packaging qualification rate to the industry-leading level while reducing the frequency of equipment shutdown and cleaning.
Industry Trend: Intelligent Driven Precision Metering
In the future, the granule packaging machine will further integrate AI prediction algorithms and high-sensitivity sensors to achieve autonomous learning and prediction of fluidity parameters, helping customers shift from "passive adjustment" to "active optimization", and provide more reliable support for the diversified packaging needs of granular materials.
