Industrial Tea Sifting Machine is mainly used to efficiently separate impurities from tea leaves, and to finely grade tea leaves of different specifications and shapes. It is widely used in high-end tea processing, beverage manufacturing and related food industries. The material contact part of the tea vibratory screener is usually made of food-grade stainless steel, which meets GMP hygiene standards and is easy to clean. A bouncing ball cleaning device is equipped under the sieve to effectively avoid tea blockage. The fully enclosed structure prevents tea leaves from being contaminated by the outside world during the screening process.

Tea Sifting Machine working Principle
Tea sifting machines usually use double-layer rotary vibrating screens. The working principle is to form a negative pressure at the feed inlet through the fan, and first effectively absorb light debris (such as small leaves or other impurities). The upper screen is responsible for preliminary screening to remove larger impurities, while the lower screen is further screened to remove small impurities in the tea leaves, such as stones, fragments or defective tea leaves. Finally, the high-quality tea leaves that have been precisely screened are discharged from the discharge port.
Uses of Tea Sifting Machine
According to the specific needs of customers, the tea screening machine can be graded according to the shape and purpose of the tea, mainly divided into broken-leaf tea and strip tea. Broken leaves are usually used in tea triangle bags, and strip tea is screened more carefully according to its appearance and integrity requirements.
- Broken tea is generally screened with 20 mesh, 30 mesh, 40 mesh, 50 mesh, 60 mesh, and other meshes.
- Tea strips are usually screened with sieves of 10mm, 8mm, 6mm, 4mm, and 2mm, such as screening small buds, pure buds, hollow buds, small leaves, etc. These mesh specifications can be flexibly adjusted according to the specific needs of tea grading.
The main function of the tea screening machine is to separate tea according to different grades, and it can also effectively remove broken tea, impurities, and substandard products that do not meet the standards. Through fine screening, the quality and taste of tea can be improved, thereby meeting the screening needs of tea producers in various places for different types of tea, and is widely used in tea processing, packaging, and quality testing.
Advantages of Tea Sifting Machine

FAQS
What is a tea sifting machine?
A tea screening machine is a vibrating screening device specially used for tea grading and screening. The equipment classifies tea leaves according to particle size, shape and quality through a screen, effectively removing impurities in tea leaves, such as stones, soil blocks, broken leaves, and other unqualified materials, thereby ensuring the purity and taste of tea leaves. The tea screening machine solves the problem of low efficiency of manual screening and difficulty in effectively removing impurities and defective products.
Common Problems And Solutions Encountered During The Application Process Of Tea Sifting Machine
Problem 1: Uneven Feeding of the Tea Sifting Machine
Reason: The tea sifting machine’s feed port is too narrow, resulting in uneven material distribution across the entire screen surface.
Solution:
- Adjust the width of the feed port to ensure uniform feeding.
- Regularly check the feeding system to ensure stable and even material entry into the tea sifting machine.
Problem 2: Excessive Material on the Screen
Reason: Large feeding volume, blocked sieve holes, and insufficient screen surface inclination.
Solution:
- Adjust the feeding volume to appropriate levels.
- Regularly inspect and clean the sieve holes to prevent blockages.
- Adjust the screen surface inclination to a suitable angle; for instance, an inclination of 20° is often effective in practical applications.
Problem 3: Insufficient Screen Surface Inclination
Reason: A common cause of poor screening performance in circular vibrating screens.
Solution:
- Raise the rear support seat to increase the screen surface inclination.
- Select an appropriate screen surface inclination based on the type of tea and specific screening requirements.
Problem 4: Blocked Sieve Holes
Reason: The feed has high mud and water content, causing materials to stick to the sieve holes.
Solution:
- Clean the sieve holes to ensure they are unobstructed.
- Adjust the water spray volume and screen surface inclination to reduce material adhesion.
Problem 5: Severe Wear of the Sieve Holes
Reason: Prolonged use of the screen.
Solution:
- Repair worn sieve holes.
- Consider replacing the screen if the wear is extensive.
Problem 6: High Bearing Temperature
Reason: Prolonged working hours and insufficient lubrication.
Solution:
- Regularly check the bearings and monitor the temperature, adjusting the working hours to maintain safe temperature levels.
- Ensure proper lubrication of all parts to maintain normal bearing operation.
General Precautions
- Choose appropriate screening equipment and screens based on the type of tea and screening requirements.
- Regularly maintain and service the vibrating screening equipment to ensure its proper operation.
- During the screening process, monitor the screening effect and adjust parameters as needed to achieve optimal results.
By implementing these methods, you can effectively increase the screening output of the industrial tea sifting machine and improve production efficiency.
