Matcha production last guide: 3 main machines in the processes and comparison

2025-08-15 17:21:30

Matcha production primarily relies on two core processes: stone-milled matcha and ball-milled matcha. The stone-milled process is further divided into granite stone milling and black gold stone milling, while the ball-milled process uses specialized ball mills. Each process, paired with corresponding equipment, differs significantly in terms of matcha quality, production efficiency, and applicable scenarios.

1. Core Matcha Production Processes

1.1 Stone-Milled Matcha

This traditional process uses natural stone mills to grind tea leaves, with two variants based on stone material:

  • Granite Stone Milling: Operates on the principle of high-speed rolling and crushing. It applies stable pressure to break tea leaves into fine powder, maintaining relatively complete chlorophyll content.
  • Black Gold Stone Milling: Adopts low-speed shearing and tearing. The dense, smooth black gold stone minimizes heat generation during grinding, which helps retain the original flavor of tea leaves to the greatest extent.

1.2 Ball-Milled Matcha

As a modern industrial process, it uses ultra-hard alumina balls inside a sealed drum. When the drum rotates, the balls impact and squeeze tea leaves, crushing them into ultra-fine powder. This method focuses on production scale and product consistency, making it suitable for mass-produced matcha.

Comparison Item Granite Stone Mill Black Gold Stone Mill Ball Mill
Equipment Material Granite Black Gold Stone Ultra-hard Alumina Balls
Processing Principle High-speed rolling & crushing Low-speed shearing & tearing Impact & extrusion crushing
Matcha Size ≈50μm ≈15μm <15μm
Flavor Complete chlorophyll retention, moderate taste Complete chlorophyll retention, best taste Partial chlorophyll damage, aroma slightly lower than stone-milled
Color Yellow-green Bright green (excellent) Dark green (above-average)
Microbial Level Open environment, higher microbes Open environment, higher microbes Sealed environment, fewer microbes
Capacity ~10 kg/h ~50 g/h ~1 kg/h
Temperature Control Slightly high heat, matcha turns slightly yellow-green Low heat generation High heat, requires use in ~25℃ rooms
Production Cost ~$0.02/kg ~$1.5/kg ~$0.15/kg
Application Scenarios Medium-end matcha (large output) Premium matcha (small-batch, high-quality) Industrial-grade matcha (mass production, e.g., ice cream, beverages)

4. Equipment Selection Recommendations

  • Premium Small-Batch Production: Choose the Black Gold Stone Mill. It offers the best matcha flavor and bright green color, ideal for high-end matcha products, despite its low capacity and high cost.
  • Medium-Scale Cost-Effective Production: The Granite Stone Mill is suitable. It balances output and quality, meeting the needs of mid-range matcha brands with large production demands.
  • Industrial Mass Production: The Ball Mill is the optimal choice. Its sealed structure ensures low microbial levels, and the ultra-fine matcha powder fits industrial applications like ice cream and beverages, with advantages in efficiency and consistency.
