Feature&Application
Factory Strength
The 5L Double Planetary Mixer with Press Feeder is engineered to deliver precise, efficient mixing for small-batch production, laboratory testing, and pilot-scale R&D across diverse industries. At its core, the dual planetary agitator system—featuring two synchronized stirrers—rotates independently at adjustable speeds (0-170 rpm) while orbiting the 5L stainless steel mixing tank. This unique motion creates intense shear and folding action, ensuring thorough homogenization of high-viscosity materials (up to 1,000,000 cP) such as adhesives, silicone rubbers, epoxy resins, creams, and pastes, eliminating dead zones and inconsistent mixing.
Integrated seamlessly with the mixer, the pneumatic press feeder automates material feeding, preventing bridging, clumping, or uneven material flow—common pain points with viscous substances. Its adjustable pressure ( 》-0.096 MPa) adapts to different material properties, ensuring a steady supply to the mixing tank and reducing manual labor. The 304/316 stainless steel tank, agitators, and feeder contact surfaces are corrosion-resistant, easy to clean, and compliant with FDA and GMP standards, making it suitable for food, pharmaceutical, and cosmetic applications.
Designed for user convenience, the mixer features a digital control panel with precise speed and time settings, allowing operators to store and recall up to 10 mixing programs. Safety is prioritized with emergency stop buttons, tank cover interlocks, and overload protection, minimizing operational risks. The compact footprint ( 950*460*1400 mm approx.) saves workshop space, while the movable base with locking casters enhances mobility.
Whether used in adhesive manufacturers’ R&D labs, pharmaceutical companies’ pilot production lines, or cosmetic firms’ small-batch cream production, this mixer delivers consistent results. It simplifies scaling up formulations from lab to production, reduces material waste, and shortens processing times. Backed by a 12-month warranty and global after-sales support, the 5L Double Planetary Mixer with Press Feeder combines durability, precision, and versatility to meet the demands of modern small-volume mixing applications.

Features
Dual-planetary Agitation Motion: The mixing paddles perform both revolution (around the central axis of the mixing vessel) and rotation (around their own axes) simultaneously, mimicking the orbital motion of planets. This unique motion ensures comprehensive coverage of the entire vessel, eliminating mixing dead zones even in the corners and bottom.
Excellent Mixing for High-Viscosity Materials: It is specially designed to handle high-viscosity substances (typically up to several hundred thousand to over a million centipoise), such as adhesives, sealants, gels, and high-concentration pastes. The strong shear and kneading forces generated by the dual motion enable thorough blending of thick materials.
Versatile Paddle Options: Various types of mixing paddles (e.g., anchor paddles, dispersing discs, sigma blades) can be configured based on material properties and mixing requirements. This versatility allows it to adapt to different processes like mixing, dispersing, kneading, and degassing.
Optional Vacuum/Pressure Function: Many models are equipped with a vacuum system to remove air bubbles from the mixture, improving product density and quality. Some can also operate under positive pressure to handle volatile or special materials.
Easy Cleaning and Maintenance: The mixing vessel can often be tilted or lifted for convenient discharging of materials. Additionally, the design of detachable paddles and a smooth inner wall of the vessel facilitates thorough cleaning, meeting the hygiene standards of industries such as food, pharmaceuticals, and cosmetics.
Stable and Reliable Operation: The equipment adopts a rigid transmission structure and high-quality components, ensuring stable operation even under heavy-load mixing conditions. It also features multiple safety protections (e.g., overload protection, emergency stop) to guarantee operational safety.
Customizable Configurations: The capacity (from lab-scale small volumes to industrial large volumes), material of construction (stainless steel 304, 316L, etc.), and auxiliary systems (heating/cooling jackets, material feeding devices) can be customized according to specific production needs.

Application Areas
Double planetary mixers are widely used in many fields, as follows:
Daily chemical products: Used in the production of emulsions, creams, shampoos, shower gels, and other products that require fine texture and stable performance.
