20L Round-Bottom Double Planetary Mixer for Small-Batch Mixing

20L Round-Bottom Double Planetary Mixer emerges as a versatile and precise solution for small-batch mixing, perfectly suited for laboratory research, pilot-scale trials, and small-volume production. With its 20L capacity and specialized design, it bridges the gap between lab-scale experimentation and commercial production, offering reliability and efficiency for diverse high-viscosity material blending tasks.

At the core of its performance is the combination of round-bottom chamber design and double planetary mixing technology. The smooth, curved round bottom eliminates corners and crevices where materials might accumulate, ensuring maximum material utilization and thorough mixing—critical for costly or high-precision ingredients. The dual planetary agitators operate through synchronized revolution (around the chamber center) and rotation (on their own axes), creating a three-dimensional mixing effect that covers every inch of the 20L cavity. This motion, paired with customizable agitator types (e.g., sigma blades, dispersing discs), enables efficient blending of materials with viscosity up to 1,000,000 cps, from thin slurries to thick pastes, without leaving unmixed dead zones.

Constructed with food-grade 304 stainless steel (316L optional), the mixer meets strict hygiene and corrosion resistance standards, making it suitable for cosmetics (e.g., creams, lotions), pharmaceuticals (e.g., ointments, gels), and specialty chemicals (e.g., adhesives, resins). The chamber’s mirror-polished inner surface not only enhances material release but also simplifies cleaning—essential for frequent batch changes in R&D settings. Operational flexibility is ensured by a frequency conversion speed control system, allowing stepless adjustment of agitator speeds (0-60 rpm for revolution, 0-3000 rpm for dispersion) to match specific material properties and mixing requirements.

User-centric features elevate its practicality: a compact footprint saves lab or workshop space; an intuitive control panel with digital displays simplifies parameter setting and process monitoring; and detachable agitators and a tiltable chamber (manual or hydraulic) facilitate easy material discharge and maintenance. For applications demanding bubble-free or oxidation-sensitive products, an optional vacuum system (capable of reaching -0.098 MPa) is available to remove air and moisture during mixing. Safety is also prioritized, with built-in overload protection, emergency stop buttons, and interlocked access doors.

Whether used for developing new cosmetic formulations, testing pharmaceutical compounds, or producing small batches of specialty adhesives, the 20L round-bottom double planetary mixer delivers consistent, high-quality results. Its blend of precision, versatility, and user-friendliness makes it an indispensable tool for industries where small-batch mixing requires both reliability and adaptability.
