Achieve uncompromised bar density, structural integrity, and a glossy, premium surface finish with our heavy-duty automatic duplex vacuum plodder. Serving as the absolute mechanical heart of continuous toilet and laundry soap production lines, this advanced double-stage plodding machine is engineered to refine, de-aerate, and compact processed soap ribbons into highly compressed, continuous soap logs. By combining two independent extrusion stages with an ultra-sealed vacuum decompression chamber, our equipment eliminates internal moisture pockets and microscopic air voids, ensuring that the final retail soap bars resist water softening, swelling, or splitting during consumer use.
Whether your manufacturing plant is scaling up anti-bacterial laundry bars or running delicate, high-end translucent cosmetic formulas, this high-yield system delivers precise extrusion control under extreme, multi-ton mechanical press loads.

Advanced Technological Features & Mechanical Highlights
1. Dual-Stage Vacuum De-Aeration & Structural Density Optimization
Standard single-stage extruders often leave tiny pockets of trapped ambient air inside the soap mass, which later cause the bar to crack and dissolve rapidly when wet. Our automatic duplex vacuum plodder solves this:
● The Upper Refining Stage: The 7.5 kW upper screw continuously forces raw soap granules through a high-shear multi-pore refining plate, slicing the material into fine noodle-like strands.
● Deep-Vacuum De-Aeration: These refined noodles drop into the central vacuum chamber (operating under negative pressures of up to -0.09 MPa). Removing all trapped air at this micro-level prevents internal bubbles from forming.
●The Lower Compacting Stage: The massive 11 kW lower screw grabs the air-free noodles, pressing and compacting them into a single, high-density soap log with a flawless, tight crystalline structure.
2. Advanced Hard-Tooth Reducer & Variable-Speed Drive Control
Handling high-viscosity soap bases under continuous operation requires a durable, responsive drive transmission system:
● High-Grade Hardened Gearboxes: Both extrusion screws are driven by premium domestic hard-tooth gear reducers. These hardened gears absorb heavy mechanical stresses, maintaining quiet operation and a long service life under high-pressure, multi-shift production schedules.
● Integrated VFD Lower Motor: The lower discharge stage is equipped with a variable-frequency drive (VFD) speed-regulated motor. This allows floor operators to adjust the log extrusion speed in real time, matching the speed of downstream electronic cutters and stamping lines to prevent material jamming.
3. Temperature-Controlled Extrusion Nozzles for a Mirror-Smooth Finish
Active Thermal Regulation: The lower outlet nozzle features an integrated, digitally monitored electric heating band system.
Surface Gloss Enhancement: Gently warming the extrusion die reduces wall friction and slightly softens the outer boundary layer of the soap log. This precise thermodynamic control allows the log to glide smoothly through the shaping mold, creating a sleek, glossy outer skin that drastically enhances the shelf appeal of your final branded soaps.
Strategic Commercial Advantages for Global Brands
Flawless Formulation Homogeneity: Forcing the soap base through two separate refining plates and vacuum compression loops ensures that essences, colors, and active ingredients are completely blended, preventing local variations or color splotches.
Unmatched Continuous Output: Designed to feed continuous, high-speed lines, the JHY-500 model easily handles a steady throughput of 500 to 800 kg/hour, making it the perfect upgrade for plants transitioning from manual batch setups to high-efficiency automated lines.
Rugged, Long-Life Construction: Weighing a solid 2,600 kg, the heavy cast-iron chassis absorbs operational vibrations and prevents mechanical alignment drift, significantly reducing your factory's yearly maintenance overhead.
