Coating of Fine Powder

We present a processing example of coating of fine powder using EIRICH mixer.
You can compare the granule condition before and after processing using SEM images, and also view a cross-sectional image of the coated particles.

EIRICH CleanLine was developed for processing raw materials that require high levels of hygiene control—such as pharmaceuticals, food products, and advanced materials—while retaining the unique mixing principle of EIRICH Intensive Mixer.Designed with hygienic specifications that prioritize cleanability and corrosion resistance, the system enables easy maintenance of sanitary conditions.There are two main series: one manufactured in Japan and the other in Germany. The Japan-made series is designed to meet the needs of customers in the pharmaceutical and health food industries, and complies with GMP guidelines covering equipment design, manufacturing, inspection, installation, and commissioning.

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.

Advantages of CleanLine

• Selecting the appropriate rotor shape and adjusting its rotational speed ensures optimal material processing.
• By adjusting the shear force, particle size and density can be controlled. This makes it possible to achieve particle size distributions such as D50 values ranging from below 200 μm to approximately 1 mm.
• By controlling the temperature through a jacketed structure, it is possible to perform granulation under cooling or heating conditions, and to process materials that are sensitive to temperature changes.
• Excellent material circulation and dispersion are achieved during both kneading and subsequent slurry formation.
