Machine Introduce
I. Core Breakthrough
High-Precision Density ControlConstant-Pressure Foaming: Utilizes an advanced constant-pressure expansion system to ensure each batch of beads achieves perfectly uniform density, even at high expansion ratios.Closed-Loop Weighting System: (Optional) Integrated high-precision electronic scale and batching system ensure raw material feeding is accurate to within $\pm 1\%$, minimizing material waste.Dual-Sensor Monitoring: Equipped with both temperature and foaming pressure sensors to maintain an ultra-stable expansion environment inside the chamber.
II. Robust Construction & Heat EfficiencyStainless Steel Chamber
The expansion chamber is crafted from high-grade stainless steel with reinforced insulation to prevent heat loss and ensure a long, rust-free service life.Heavy-Duty Fluidized Bed: Features an integrated stainless steel fluidized drying bed with a high-power blower to ensure beads are dried and cooled instantly after expansion.Advanced Agitation Design: The bottom-driven stirring system prevents bead clumping during the heating process, ensuring every bead receives equal steam penetration.
III. Optimized Steam & Energy ManagementProportional Valve Technology
Features a high-response proportional valve for steam intake, allowing for delicate adjustment and saving up to 15-20% in energy compared to traditional on/off valves.3D Steam Penetration: Optimized steam vent positioning ensures rapid heating cycles and deep penetration, which shortens the cycle time and boosts overall factory throughput.Efficient Compressed Air System: Precision-engineered air injectors facilitate rapid cooling and discharging, further reducing the total energy footprint per ton of material.
IV. Intelligent Automation & User InterfaceFull Process Automation
Controlled by a Mitsubishi PLC and Schneider touch screen, managing the entire cycle—from vacuum feeding and weighing to heating, drying, and discharging.Smart Memory Functions: The system can store over 100 sets of production parameters for different raw materials, enabling one-touch "recipe" switching for rapid production changes.Remote Oversight & Safety: Includes an integrated remote monitoring module for troubleshooting and real-time data logging, alongside multi-level safety relief valves.
