Tea Powder and Broken Tea Content Testing

Due to the repeated up and down of sieving, wind selection, and re-fire in the refining process, the powder and broken tea will be increased. If the blending is improper, there may be too much powder and broken tea content, resulting in cloudy tea soup and reduced aroma in brewing, affecting the product's market competitiveness. In addition, there are also special tea bags that are made for specific broken tea. So broken tea bags may not be a good tea, depending on the specific circumstances of the factory, and can not be generalized. The powder content of tea is limited in the export tea standards, and the control of the crushed tea content shall not exceed the actual content of the standard or deal sample tea.

Solutions

The amount of powder and broken tea content is one of the quantitative indicators of the whole and broken condition of the tea leaf shape. As a recognized leader in tea testing, Lifeasible can develop the best tea powder and broken tea content testing solution to help customers test the powder and broken tea content in imported and exported teas to assess the whole tea shape.

We offer a standard method for powder and shattered tea content determination, based on shattered and powdered tea samples sifted through a defined test sieve and under defined operating conditions, weighed separately, and their content calculated. We have the necessary instruments and equipment for the powder and broken tea content testing method, including but not limited to:

• Samplers and splitting plates.
• Electric sieving machine (200 rpm, 60 mm gyration range).
• Inspection sieves (standard sieves with steel wire woven square holes, sieve diameter 200 mm, height 57 mm, with sieve bottom and cover combination).

Powder sieve specifications are:

(1) Standard sieve 630 μm for strip and round tea.

(2) Standard sieve 450 μm for broken and coarse shaped tea.

(3) Standard sieve 280 μm for flake tea.

(4) Standard sieve 180 μm for end-shaped tea.

Broken tea sieve specifications are:

(1) Standard sieve 1.25 mm for strip and round tea.

(2) Standard sieve 1.60 mm for coarse tea, etc.

Strip, round tea generally contains work black tea, small black tea, black crushed tea in leaf tea, Zhen Mei, Gong Xi, bead tea, rain tea, and flower tea. Coarse shaped teas contain Tieguanyin, color seeds, oolong, Shui Xian, Qi seeds, white peony, Gong Mei, and Pu'er loose tea.

We will develop customized tea powder and broken tea content analysis steps for different tea shapes. Powdered and crushed tea is strictly sieved off through a specified aperture sieve. If you are interested in our solutions, please contact us for technical consultation and quotation.
