Circular vibrating screen separator mainly for sorting different size of tea dust/powder/fragment, used for CTC tea or other crushed tea leaf, Optional different screens to get different sizes of tea.
100kg fresh leaves process 25kg finished oolong tea in 12 hours, This page recommends you a full set of green tea production equipment and use methods.
The matcha stone mill is made of granite that is cut in one piece. After the initial grinding process, no stone powder or slag is lost during use, which ensures the safety and cleanliness of the matcha tea.
The main function of the electric bamboo drum baking cage is to replace the carbon baking cage, making the drying of tea more precise and controllable.
Before the round type tea ball made, the raw tea still need to process by tea withering machine, tea fixation machine, tea roller and tea dryer.Then shaping by the dragon te ball shaping machine.
Before shaping the dargon ball tea, the raw tea still need to make thoug tea withering, tea fixaiton, tea roling and tea drying.
Doing a good job in tea garden management can make the value of spring tea more enhanced.
Black tea fermentation has traditional fermentation and machine fermentation, and machine fermentation will become a trend of black tea fermentation.
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.
