The step of fixation is mainly used for the production of various unfermented or semi-fermented teas. The activity of the enzyme in the fresh leaves is reduced by high temperature, the tea polyphenols in the fresh leaves are stopped for oxidative fermentation, and the odor of the grass is removed, the aroma of the tea leaves is excited, and the moisture in the fresh leaves is evaporated. The fresh leaves become softer, which is conducive to the subsequent rolling process, and the tea leaves are not easily damaged.

After fixation, the green tea need to be cooled. Let the temperature of the tea leaves lower and distribute moisture to prevent high-temperature moisture from smothering tea.

When tea fixation, pay attention to "young leaves with high temperature and faster, old leaves with lower temperature and slower", which means that the young leaves need high temperature to fixation quickly, killing the enzymes in the tea faster, while fixation for a short time, will not damage the tea. Old leaves need to fixation at low temperature and slow speed. The leaves of old leaves are thicker, if high temperature is used, the heat cannot be transferred to the inside. The leaves on the outside are scorched and the leaves on the inside are not yet cooked. Such tea leaves are useless.

Tea fixation is also known as , Tea Steaming, Tea Roasting .etc, although the names are different, but the functions are the same. The most mainstream fixation method currently uses roasting fixaion process, which makes the tea taste more fragrant.

The method of tea fixation, the common ones are steam fixation, roasting fixation, hot wind fixation

 

  1. Green Tea Steaming fixation

At the name implies, the steaming of green tea is to use steam to fixation the tea leaves. China is the birthplace of tea. The most original fixation process of green tea is steaming. Chinese green tea was introduced to Japan during the Tang Dynasty. At present, the main method of fixation green tea in Japan is steaming.

Advantage: Using steaming to fixation, the tea leaves are fixation more uniform, and the color is greener, and the chlorophyll damage is less. At the same time, there is no pressure during the processing, so the color of the steamed green tea and the color of the tea soup are green and the appearance is better.

 

Disadvantage:  The tea tastes lighter and more astringent, and it also has some grassy taste, which does not meet the taste of most people. Moreover, the process of steaming  green tea is very old, and it is almost eliminated in China. About 600 years ago (around 1400, during the Ming Dynasty of China), clever and hardworking Chinese tea farmers invented roasted green tea. Because the taste of roasted green tea is many times better than steamed green tea, and the taste is stronger, roasted green tea has gradually replaced steamed green tea. At present, the production of steamed green tea is very small, mainly concentrated in Japan and Hubei Enshi City.

 


 

 

  1. Tea Roasted fixation

Fried tea is the most popular way to fixation in the world. Let the tea leaves touch the wall of the high temperature pot and roast the tea leaves at high temperature. About 600 years ago, the Chinese invented fried green, and gradually promoted it throughout the country. At present, the production of fried green tea accounts for more than 90% of the total amount of green tea.

 

2-1  Hand firing pot fixation, there are three types of pots currently available for selection:

An iron pot, then build a stove with bricks and cement, and burn wood or coal at the bottom. This is the oldest way to fixation, and it is also the way to fixation high-end green tea. If the workers have extensive experience, then the green tea produced by this method is of the highest quality.

Advantage: Small footprint and the operation is simple. If the producer is experienced, the quality of the green tea is extremely high and the taste is more fragrant.

Disadvantage: Due to the use of wood heating, the temperature is difficult to control. High demands on the producer's experience, if the temperature is high, it is easy to burnt. And if the temperature is low, it is not easy to get enough aroma , which affects the quality of the tea.

 


 

2-1-2 Electric heating hand firing fixation-wooden base

Using electric heating, with wooden base, can be processed at different heights, easy to use, the main production equipment for medium or high-end green tea. If the workers have extensive experience, then the green tea produced by this method is of the highest quality.

Advantage: Small footprint, easy to control the heating temperature, it is easy to operation.  If the producer is experienced, the quality of the green tea is extremely high and the taste is more fragrant.

Disadvantage:  High demands on the producer's experience. If the temperature is high, it is easy to burnt. And if the temperature is low, it is not easy to get enough aroma, which affects the quality of the tea.


 

 

2-1-3 Electric heating hand firing fixation- stain steel base

Using electric heating with stain steel base, adjustable height, ergonomic, easy to use.  The main production equipment for medium or high-end green tea. If the workers have extensive experience, then the green tea produced by this method is of the highest quality.

Advantage: Small footprint, easy to control the heating temperature, it is easy to operation.  If the producer is experienced, the quality of the green tea is extremely high and the taste is more fragrant.

Disadvantage:  High demands on the producer's experience. If the temperature is high, it is easy to burnt. And if the temperature is low, it is not easy to get enough aroma, which affects the quality of the tea.

 


 

 

2-2 Fixation machine: There are currently three kinds of machines to choose from:

2-2-1 Stand-alone drum type tea fixation machine

Drum type tea fixation machine could heat ny gas or electric. Heating with high efficiency, environmental protection and sanitation, good fixation effect; With exhaust function, it can exhaust hot and humid air inside the machine; The tea has good color, full fragrance, complete leaves, and no loss of nutrients.  It is currently the most used equipment on the market. And different machines can be customized according to different output, which can meet the green tea production needs of most regions and people.

Advantage: Heating efficiency of gas/electric is high, the temperature rises quickly; the tea color is good, the fragrance is more sufficient, and the machine can be customized to meet the tea production needs of different people in different regions. The green tea quality made with this machine is middle or high-end.

Disadvantge: If the output is very large, this machine will not be suitable.

 


 

 

2-2-2 Automatic imitation artificial tea fixation pot

This gas-heated Chaotian pot killing machine highly imitates the process of hand-fried tea. The pot body of our machine can rotate 360 degrees, this is an industry first. The tea leaves are heated without dead ends, and the fixation more uniform. We are the first in the industry to install a hot air pipe on the pot body, and can independently choose whether to blow hot air into the machine. The water vapor in the pot can be quickly drained to prevent the tea leaves from becoming yellowish and affecting the quality of the tea leaves. The patented guide bar and the taper of the pot body are adopted, which highly imitates the hand-fried tea of the master and perfectly approximates the quality of hand-made tea. Our machine occupies most of the market in the production area of high-end Pu'er tea!

Advantage: The patented pot design is perfectly close to the method of hand-fried tea. The quality of the finished tea leaves is the top quality, which is the only choice for automatic frying of high-end tea.

Disadvantage: The price is slightly higher, and the processing time of the tea is slightly longer, resulting in a not very high output.

 


 

 

2-2-3 Continuous drum type tea fixation machine

Continuous drum fixation machines have similar functions as stand-alone drum fixation machines. Continuous drum killing machines are also very popular on the market, and can be heated by electricity/firewood/gas to meet the production requirements of people in different regions.

Advantages: High processing efficiency and labor saving.

Disadvantages: Large footprint, not suitable for small home workshops, the taste of the tea produced is not as good as the stand-alone equipment.
