This White Stone Matcha Mill can grind tea leaves into 15μm ultrafine matcha powder.
The DQM-150 features a robust 110L inner and outer 304 stainless steel tank powered by an 11kw pure copper core reduction motor. The machine employs an automated feeding system with a 60L large-capacity hopper, transferring raw materials via a flexible screw conveyor driven by a speed-adjustable motor (0-300r/min).
The Matcha ball mill is designed for post-drying grinding of agricultural products (e.g., ground tea, Chinese medicinal materials) with advantages of low-temperature grinding (15-25℃) to retain raw material color and aroma, fine fineness (500-1000 meshes), PLC-controlled easy operation, and durable structure.
This smart electric stone mill seamlessly combines traditional low-temperature grinding with modern automated features to effortlessly produce ultra-fine, premium commercial matcha.

1. The effect of temperature on enzymes
There are many enzymes in tea. For example, the presence of polyphenol oxidase can catalyze the oxidation of polyphenols and make the leaves red. If a certain method is used to destroy the activity of polyphenol oxidase, the polyphenols will lose the conditions for the oxidation reaction, so they will not quickly turn red. The "fixation" process in green tea processing is to use high temperature to "Passivation" the activity of enzymes, so that the polyphenols will not be enzymatically oxidized during the subsequent rolling and drying process, thereby maintaining the green leaves of the clear soup.
The purpose of "fixation" is to use high temperature to destroy the oxidase activity, but if it is not handled properly, not only will it not destroy the enzyme activity, but it will increase the enzyme activity, causing red tea leaves and green leaves. It can be seen that the temperature has a duality on the enzyme, that is, it increases the speed of the catalytic reaction. At the same time, the speed of the passivation reaction is also increased under high temperature conditions.
It is irreversible that the enzyme is destroyed by heat, but sometimes the fixation temperature is not high enough, and the enzyme activity is inhibited without being destroyed. After the high temperature is relieved, it will regain vitality, and red stems and green leaves will appear when they are twisted or dried.
