MIX15L Vacuum Mixer‑Defoamer_15L Ultra‑large Capacity Industrial‑grade Vacuum Defoaming Equipment‑SIENOX

Why Must Microbubbles in Materials Be Eliminated?

Residual micro‑bubbles in large‑volume high‑viscosity materials directly affect product yield and performance stability.

Recommend application cases for SIENOX SIE‑MIX15L Vacuum Mixer‑Defoamer.

3D Printing Industry

Bubbles in large‑size 3D‑printing resin slurries create inter‑layer voids, weakening interlayer bonding and mechanical strength of printed parts. Bubbles in ceramic 3D‑printing slurries generate internal pores after sintering, impairing dimensional accuracy and density. Bubble issues are amplified in mass‑material production; uneven bubble distribution across batches causes quality fluctuations among multiple printed parts.

Polyurethane Industry

Bubbles in cast polyurethane elastomers degrade mechanical properties including elasticity, wear resistance and load‑bearing capacity. Uneven bubble distribution in polyurethane foams produces density gradients and deteriorates thermal‑insulation and cushioning performance. In mass polyurethane production, bubbles directly harm product consistency and yield. 15L large‑volume processing reduces batch‑split cycles and minimizes batch‑to‑batch deviation.

Aerospace & Defense Industry

Bubbles in aerospace composite resin matrices form stress‑concentration spots and reduce interlaminar shear strength and anti‑fatigue performance of composites. Bubbles in aerospace thermal‑conductive potting compounds lower heat‑dissipation efficiency and reliability of electronic devices. The aerospace‑defense sector allows extremely low material‑defect tolerance. Residual micro‑bubbles may trigger critical‑component failure, hence strict requirements for defoaming processes.

✨ **Traditional Defoaming Dilemmas**: Manual stirring for large-capacity and high-viscosity materials features low efficiency and uneven mixing. Conventional small-capacity equipment requires repeated batch processing, making it difficult to guarantee batch consistency. Static defoaming delivers limited results on high-viscosity materials with extremely long processing time. The large-capacity vacuum mixing and defoaming technology applies -98kPa vacuum negative pressure during planetary stirring. It processes 15L materials in a single run, reducing batch operations and ensuring consistent quality for mass production.

Why Choose MIX15L

Specially built for heavy‑industrial mass‑production vacuum defoaming with extra‑large capacity

15L High‑capacity Design

Standard dual‑station loading of 15L per cycle. Low‑speed high‑torque transmission adapts to ultra‑high‑viscosity heavy slurries. 0‑30L expansion customization is available to meet factory 24‑hour continuous batch‑processing requirements.

Planetary Transmission System

Reinforced frame and heavy‑duty gear structure with switchable planetary speed ratio. Strong centrifugal force disperses high‑fill powders to reduce material sedimentation and agglomeration, supporting long‑term non‑stop operation.

Production‑line‑grade Intelligent Control

Multi‑level permission touch screen stores multiple mass‑production recipes. Compatible with factory MES system for full‑process data logging. Equipped with multi‑fold safety protection for overload, vacuum and door interlock, suitable for standardized industrial production lines.

✨ When vacuum defoaming is required and production volume reaches the 5000 mL level, the MIX5000 serves as a pilot‑scale option for small‑to‑medium batches within the planetary vacuum mixer‑defoamer series.

Working Principle

Adopt collaborative process of planetary revolution, container rotation and high‑vacuum sealing

Planetary Revolution: High‑power main shaft drives the turntable for low‑speed high‑torque revolution, generating steady continuous centrifugal force. It pushes high‑viscosity and high‑filler materials to adhere evenly against vessel walls and suppress sedimentation and delamination of heavy‑weight powders.

Container Rotation: Material buckets rotate synchronously in reverse direction, generating extensive fluid shear inside containers. No impeller contacts materials to minimize metallic impurity contamination, ideal for heavy high‑solid‑content slurries.

High‑flow Vacuum Defoaming: Large chamber paired with high‑flow vacuum pump builds rapid and stable negative pressure. Deep‑seated micro‑bubbles inside materials rise and separate under pressure difference. Mixing and defoaming proceed simultaneously to eliminate separate defoaming steps, matching the rhythm of continuous mass production.

How does the stirring and defoaming machine work?

The SIENOX stirring and defoaming machine performs defoaming through centrifugal force at revolution and stirring through shear force formed by revolution and rotation,
Assisted by a vacuum pump to extract gas and achieve a vacuum state, removing nanoscale tiny bubbles. No contact with materials, no secondary pollution, and no secondary waste.
What is the function of a defoaming machine?

A defoaming machine is a device used to remove bubbles from liquids. Its function is to assist in the liquid mixing, reaction, coating, printing, infusion and other process steps in the production process, avoiding the generation of bubbles and their impact on the final product. In many industrial and laboratory environments, removing bubbles is essential as they may have a negative impact on product quality, such as affecting surface tension and stability. Defoaming machines typically use various techniques such as vibration, ultrasound, centrifugation, etc. to achieve effective bubble removal. It has a wide range of applications, including but not limited to semiconductors, solar energy, optics, biotechnology, materials science, etc.
