As the core equipment of modern continuous granulation technology, the fully automatic swing granulator has achieved high-precision and low-energy particle preparation in the fields of pharmaceuticals, food, and special materials through integrated intelligent control and mechanical optimization design. Its technological evolution path demonstrates a leapfrog development from basic mechanical structures to intelligent production units.
1、 Core structure and operational characteristics
The equipment adopts a closed modular architecture, mainly composed of an intelligent transmission system, a dynamic screening module, and an online monitoring unit. The servo motor drives the seven corner drum to perform 360 ° reciprocating swing (55r/min reference speed), and achieves stepless adjustment of 0.5-15mm amplitude through vector torque control. The material is granulated under the squeezing and shearing action of the drum and the arc-shaped screen mesh. The tension of the screen mesh is fed back in real-time through an piezoelectric sensor, automatically compensating for the particle size deviation caused by the deformation of the screen hole. Compared to traditional models, the fully automatic system has added the following functional units:
1. Bidirectional fabric mechanism: The feeding hopper with a spiral conveyor belt can adapt to materials with a flowability difference of up to 30%, and achieve uniform material laying through vibration frequency adjustment.
2. Humidity control component: Integrated microwave moisture sensor and atomizing nozzle, controlling the humidity fluctuation in the granulation environment within ± 1.5% range.
2、 The evolution of intelligent technology
1. Adaptive granulation algorithm
The material feature library established based on deep learning models can autonomously set the drum amplitude and screen clearance according to parameters such as powder angle of repose and packing density. When processing high viscosity materials (5000cP), the system will trigger pulse vibration to eliminate screen blockage.
2. Digital Twin Maintenance System
Predicting bearing life through vibration spectrum analysis, with an accuracy error of less than 8 hours. The worm gear box is equipped with an oil metal particle detection module, which triggers a warning when the concentration of iron filings exceeds 50ppm.
3. Flexible production adaptation
The quick release drum component supports switching the mesh size (20-120 mesh) within 5 minutes, and models with titanium nitride coating on the mesh surface can extend the service life to 8000 hours.
3、 Cross industry application performance
1. In the pharmaceutical field, when producing instant granules, 85% -95% spherical particles are obtained by adjusting the frequency of the drum swing (200-600 times/minute) to meet the consistency requirements of drug dissolution.
2. Food processing: When handling hygroscopic materials such as milk powder and seasonings, the temperature control system can stabilize the chamber temperature within the range of ± 2 ℃, and the moisture content fluctuation of granular products is less than 0.3%.
3. Fine Chemicals: Adapting to brittle materials such as catalyst carriers, the innovatively designed buffer granulation chamber can reduce the crushing rate to below 3%.
