Anti-adhesion Technology

For businesses handling powders and granular materials, material adhesion and residue inside containers pose significant challenges. These issues affect product quality, yield, labor efficiency, and worker safety.

Challenges Arising from Adhesion

• Quality variations caused by material adhesion
• Lower product yield
• Additional labor hours needed for cleaning and maintenance
• Safety considerations for workers during cleaning operations

Product Requirements

• Reduction of material adhesion
• Improvement of product yield
• Reduction in cleaning and maintenance labor
• Minimizing worker contact with materials

Five Eirich Technologies Designed to Reduce Material Adhesion. Through our unique engineering, we provide comprehensive adhesion control for the top, sides, and bottom of the Mixing pan (mixing container), ensuring consistent and reliable performance.

1. Flat Structure of Mixing Pan (Mixing Container)
   The flat, obstruction‑free design of the Mixing pan enhances cleanability and prevents material buildup.
2. Adhesion Prevention with Tool Set (Scraper)
   The Tool set installed along the inner surface of the Mixing pan scrapes off materials adhering to the inner walls and bottom, effectively reducing residue.
3.  Bottom Tool on the Rotor Tool (Mixing Tool)
   The Bottom tool mounted at the lowest point of the Rotor tool prevents material adhesion on the container bottom.
4. Temperature Control with Cooling and Heating Capabilities
   A Mixing pan equipped with cooling and heating capabilities allows precise temperature control during processing, preventing adhesion caused by temperature fluctuations.
   Note: This feature is available on selected Intensive Mixer models and on the “CleanLine” series designed for hygienic applications.
5. Reverse Jet Nozzles
   By spraying compressed air, these nozzles reduce material adhesion and residue on the Crosshead (top plate).
   * This feature is available only on the "CleanLine" series for hygienic applications.

Cleaning is required for any remaining adhered material. However, both the Tool set and the Rotor tool are detachable and can be washed with water, ensuring excellent cleanability and ease of maintenance. Additionally, for small mixers with a working capacity of up to 5L, the mixing pan can also be removed and washed with water.

The Eirich mixer’s combination of versatile adhesion‑prevention features and a highly cleanable design helps ensure product quality and protect operator safety.

Eirich Intensive Mixer is a high-speed mixer and granulator designed for a wide range of processing tasks involving raw materials, mixtures, and compounds.Optimal material processing is achieved by selecting the appropriate mixing tool shape and rotation speed according to the application.
By adjusting the operating conditions, a single machine can handle multiple processes such as mixing, granulation, kneading, and slurry preparation.The mixer features a jacketed mixing pan for both cooling and heating, and offers a wide range of customizable options to accommodate various processes.

Advantages of the Eirich mixing principles

1. Eccentrically positioned rotor tool (mixing tool)
   The rotor tool shape, rotation direction, and speed range can be selected to suit the application.
2. Tool Set (scrapers)
   It scrapes off raw materials adhering to the inner wall and bottom of the mixing pan, while simultaneously promoting efficient material transfer to the rotor tool.
3. Mixing Pan (mixing vessel)
   Through rotation, all raw materials in the mixing pan are continuously supplied to the rotor tool.

Unique Mechanisms

• Short mixing time and high homogeneity
• Capable of processing raw materials with varying specific gravities
• The rotating mixing pan promotes material movement and reduces residue.
• By selecting the rotor tool shape and adjusting the mixing pan speed, the system can handle complex material processing
• Process integration enables compact and energy-efficient production systems
• Setting optimal operating parameters ensures consistent and reproducible material processing
