Process Revealed: Why Top-Tier Matcha Requires "Secondary Screening"

— DL-6CZDS-60 Circular Vibration Screening Machine: Your Final Defense for Quality

In the world of premium Matcha production, a common question arises: "We use high-precision stone mills, so why does the powder sometimes still feel 'clumpy' or have a rough mouthfeel?"

The answer lies not in the grinding, but in the screening.

Today, we introduce the essential partner in the Matcha processing line: the DL-6CZDS-60 Circular Vibration Screening Machine. Discover how this equipment helps factories stabilize Matcha fineness at 500 mesh and above, delivering the silky texture that the market demands.

Circular Vibration Screening Machine

1. Why Screen After Grinding?

While stone mills can grind tea leaves down to microscopic levels (800-1000 mesh), packing the powder directly after milling poses two risks:

  1. Static Clumping: Matcha powder has a massive surface area. During grinding, friction generates static electricity, causing the fine particles to stick together into small lumps. This ruins the consumer's whisking experience.

  2. Inconsistent Particles: Even the best mills might occasionally let through a coarse leaf fragment.

The DL-6CZDS-60 solves this. It doesn't "grind" the tea; it uses high-frequency 3D vibration to break up static clumps and filter out any imperfections, ensuring every gram of Matcha is fluffy and uniform.

2. Key Features & Advantages

  • High-Accuracy Screening: Designed for ultra-fine powders, it easily handles 200 to 500 mesh requirements, ensuring high efficiency and precision.

  • 3D Vibration Trajectory: The motor drives an eccentric hammer to create a unique 3D motion (horizontal, vertical, and inclined). This forces the powder to spread rapidly across the screen, significantly increasing throughput and preventing mesh blockage.

  • Food-Grade Hygiene: The entire machine body (contact parts) is crafted from SUS304 Stainless Steel, which is corrosion-resistant and easy to clean, meeting strict GMP food safety standards.

  • Continuous Operation: Coarse materials and impurities are automatically discharged, allowing the machine to connect to your production line for 24/7 automated operation.

3. The Standardized Matcha Processing Flow

In a modern tea factory, this machine sits at the critical junction after milling and before packaging:

  1. Preparation: Tencha leaves are crushed.

  2. Ultra-Fine Grinding: Electric stone mills (like the DL-6CYM series) grind the tea into powder.
