How Does Liquid Nitrogen Freezing Mill Crush Tea

Liquid nitrogen cooling mill is a kind of grinding equipment that uses liquid nitrogen for cooling. The boiling point of liquid nitrogen is -196℃, and the gas in the crushing room is cooled to an ultra-low temperature state, which can reduce heat and friction to achieve the effect of crushing. Liquid nitrogen cooling mill uses the low temperature characteristics of liquid nitrogen to crush crushing materials, especially suitable for the crushing of polymer materials, metals, non-metallic materials, etc.

1. High crushing efficiency: liquid nitrogen cooling crusher has high crushing efficiency and can quickly and efficiently crush materials into the required particle size.

2. Controllable crushing size: liquid nitrogen cooling mill can control the crushing size by adjusting the cooling temperature and crushing time to meet different crushing needs.

3. High crushing quality: When the liquid nitrogen cooling mill pulverizes the material, the friction and heat are greatly reduced, which can ensure the quality of the crushing material.

4. Wide range of application: liquid nitrogen cooling crusher is suitable for the crushing of various polymer materials, metals, non-metallic materials, etc.

The main reason for using liquid nitrogen freezing crusher to crush oily tea is that the low temperature of liquid nitrogen can effectively protect the oil content and aroma of tea. The specific reasons are as follows:

Avoid oil volatilization: Tea contains a certain amount of oil, which is easy to volatilize or deteriorate at room temperature. The use of liquid nitrogen freezing shredders can reduce the temperature, avoid the oil being destroyed during the crushing process, and maintain the flavor and aroma of the tea.

Reduce heat damage: Traditional crushing methods often generate heat, resulting in thermal damage to the active ingredients in the tea (such as polyphenols, amino acids and oils), reducing the quality of the tea. The low temperature of liquid nitrogen can effectively inhibit this thermal effect and protect the nutritional components of tea.

Improve the crushing effect: When the liquid nitrogen is frozen and crushed, the tea becomes more brittle, easy to crush into finer particles, and the crushing effect is better. This method enables the tea to achieve a finer powder state while maintaining the original quality.
