Pu-erh Tea Powder Freezing Mill
Introduction
The Pu-erh Tea Powder Freezing Mill is used to grind pu-erh tea into a fine powder while maintaining its flavor, aroma, and healthful ingredients. In a manner not possible with conventional milling techniques, this kind of mill handles the tea leaves by using freezing technology.
Before milling, the tea leaves are usually quickly cooled using liquid nitrogen or other cryogenic techniques in the freezing mill. The mill may crush the tea leaves into a fine powder without using too much heat because the chilly temperatures cause the leaves to become brittle. This procedure aids in maintaining the original tastes and volatile substances, which are susceptible to deterioration at elevated temperatures.
Material Characteristic
After crushing treatment, the powder of Pu 'er tea is usually very fine and has a uniform particle structure. Fine powder can be better dissolved in water, releasing rich tea aroma and taste. Pu 'er tea powder preserves the aroma of the original tea, and has a special aging aroma or the unique taste of ripe tea. When liquid nitrogen is frozen and crushed, these volatile aroma components can be effectively maintained to prevent aroma loss due to high temperature. Pu 'er tea itself contains a certain amount of camellia oil, and the powder of Pu 'er tea can still maintain these oil, tea oil helps tea taste more rounded, smooth. The oil also helps to lock in the aroma and taste of the tea.

FAQ
1. Q: What is a pu-erh tea powder freezing mill?
A: The pu-erh tea powder freezing mill is a specialized milling machine that uses liquid nitrogen to freeze and pulverize pu-erh tea leaves. The freezing process preserves the natural flavor, aroma, and active compounds of the tea, resulting in a finely ground powder while avoiding heat-induced damage.
2. Q: Why is freezing necessary for grinding Pu-erh tea?
A: Freezing the tea helps prevent the oil and volatile compounds in the tea leaves from evaporating or degrading due to heat during the milling process. This results in better preservation of flavor and aroma, which are essential to high-quality Pu-erh tea.
3. Q: What kind of maintenance does the pu-erh tea powder freezing mill require?
A: The pu-erh tea powder freezing mill typically requires maintenance in terms of ensuring the liquid nitrogen supply is constant, cleaning the mill after use, and ensuring that all moving parts are functioning correctly. Regular inspection of the freezing mechanism is important to ensure its efficiency.
