Tea’s mellow and fragrant aroma comes from drying some fixed water content to remove the fresh green

2023-10-19 14:18:25

Do you know something about the formation of tea? In our life, we may as well have some tea lovers who have studied tea, so we should understand that tea green removing is a very important tea-making process, most of the tea needs fresh green removing.

Tea is rich in polyphenol oxidase. If we do not remove some water content first, polyphenols will be oxidized and fermented under the action of enzymes, so that the tea will quickly lose its color and then spoil. Only by removing some water content first can the fragrance be emitted. As far as the known ways of removing fresh green tea are concerned, the equipment of tea microwave machine is the most efficient. In the process of tea processing, the removing some fixed water content is the key process to improve the quality of tea processing, and plays a key role in the shape and quality of tea.

At the present stage, in the rapid development of industrialization, according to the commonly used ways of removing some water content, the main methods of killing green include drum-type, hot air, steam and new microwave tea machinery and equipment. The effect of drying tea and the quality of tea are different with different equipment.

Common tea drying equipment:
1. Electric Heating 70cm Diameter Middle Type Green Tea Panning Machine, continuous operation, convenient use and good quality of tea. The finished tea is emerald green, fragrant and tasty. It has also been widely used in tea production in China. The disadvantage of drum dryer is that if the operation method is inappropriate, it will often cause the phenomenon of coke leaves.

2. Hot-air tea-drying machine is a new product developed successfully in Zhejiang tea area in recent years. At present, it is widely used in Zhejiang, Sichuan and other places. Its main structure is composed of hot air generator, cylinder, fresh leaf hoist, belt conveyor and cooling unit. However, hot air is selected to drying at 300-350 C. The temperature difference between hot air and fresh leaves is large. The process of drying green tea is usually completed in a very short time. It is difficult to control the process. If there is a slight misoperation, it is easy to form a burning edge and a bursting point, and the tea contains the odor of smoke and char.

3. In China, discontinuous box-type or mesh-belt type non-pressure steam-type green tea drying machines are commonly used in the way of steam-type green tea drying and the application of mechanical equipment. The structure is composed of feeding device, transmission device, vane conveying device, steam cleaning device, cooling device and other components. The moisture content of steam-drying leaves is generally slightly higher than that of fresh leaves. Although the leaf texture has softened, it can not be rolled or shaped immediately. It needs to be first baked so that the moisture content of steam-dried leaves can be reduced to 55% before entering the normal next process.

4. Microwave tea-drying machine is a new type of tea-drying machine developed successfully in recent years in our country. The process of microwave tea-drying is a process in which heat is generated from the inside of the green tea leaves. There is no temperature gradient inside and outside the green tea leaves. There is no heat transfer process of general heating. It has fast heating, preheating time and low heat loss, which is conducive to automatic control and continuous production. The tea products treated by microwave green-killing machine have less chlorophyll change, green color, uniform drying and less loss of aroma, so as to achieve good green tea drying effect.
