Why Tea Need Sorting? (1)

Tea screening is an important part of tea processing and refining. Screening in different ways can improve the quality, appearance and taste of tea. The specific benefits are as follows:


1. Grading and grading to ensure uniform quality

Classification by size and shape: Tea leaves, buds and broken pieces of different sizes will be produced during the processing process due to rolling, fermentation and other steps. Screening can classify tea leaves into different grades (such as special grade, first grade, second grade, etc.) to ensure the same quality of the same batch of tea leaves.

Increase the value of goods: neat and symmetrical tea leaves (such as bud tea, one bud and one leaf) are sold at a higher price, while broken tea and tea powder are usually used for tea bags or low-priced products.


Using the Plane circular screening machine produced by our company, it can be equipped with 4 layers of screens and 5 layers of outlets. The upgraded machine is more silent and can effectively screen the size of tea leaves. So as to achieve the ideal effect of tea grading.


2. Remove impurities and improve purity

Exclude non-tea substances: such as tea stems, yellow flakes, old leaves, sand and gravel, insect-infested leaves, etc., to ensure that the tea leaves are clean and hygienic.

Reduce bad flavor: Tea stems and old leaves may bring a rough taste, and removing them makes the tea soup more mellow.


Tea Electrostatic Dust Removal Clearner Machine is a very efficient impurity removal equipment. It effectively absorbs impurities such as hair, feathers, plastic, dust, etc. in tea leaves through electrostatic rollers to generate static electricity, thereby improving the cleanliness of tea leaves. The cleanliness can reach more than 95%, which is a necessary cleaning equipment for high-end tea.
