Types of tea leaf sieve machine

Tea leaf sieve machine is mainly used to separate the tea leaves that have been broken, to disperse the agglomerated tea leaves, to screen and remove impurities and secondary tea. According to different screening purposes and requirements, the tea leaf sieve machine can be divided into the following three types.

3 types of tea leaf sieve machine

1. Tea linear sieve machine

The linear tea sieve machine is mainly used in the tea refining process. The bar-shaped tea leaves are screened by a vibrating sifter to remove impurities and inferior teas, improve clarity, pure quality, and ensure hygiene. Maocha is processed into commercial teas of various colors and grades according to different traits and qualities. This screening process is mainly divided into different sieve numbers according to the physical characteristics and the different length and coarseness of the tea. The sieving aperture of the strip tea leaves is mainly 10mm, 8mm, 6mm, 4mm, 2mm according to the different processes. The linear tea sieving machine is suitable for all kinds of dry powder or granular materials with a moisture content of less than 7% and no viscosity. For screening, the feed size is not more than 10mm, and the processing capacity can reach 20 tons per hour.

2. Tea vibro sifter

Tea vibro sifter is used in the sorting of crushed tea powder. Because the dried tea powder has a lighter specific gravity, a low penetration rate, and a high probability of floating, the vibrating screen manufacturer (Dahan Machinery) recommends using an ultrasonic spinner. Vibrating the sieve to sort the powdered and broken tea. The ultrasonic rotary vibrating sieve of tea powder can easily solve the blockage of the mesh, and it can also improve the screening output and precision. The sieving meshes of broken tea can be divided into 20 meshes, 30 meshes, 40 meshes, 50 meshes, 60 meshes, 100 meshes, etc. according to different application industries. After testing, for the finest 100-mesh crushed tea powder, the screening efficiency of the 800mm diameter tea powder ultrasonic rotary vibrating sieve can reach 80kg/h, which is 4 to 5 times that of the ordinary circular vibrating sieve.

3. Tea sorting sieve

Tea sorting sieve is used in tea inspection. According to national regulations, tea on the market must meet the GB/T8311-2002 national standard "Determination of Tea Powder and Broken Tea Content". Inspection sieve) The sieving method is used to determine the content of powder and broken tea in tea samples. The tea sample sieve is mainly composed of a standard vibrating sieve and a tea standard sieve. The tea standard sieve is composed of 6 stainless steel sieve grids with different apertures and a set of upper and lower covers. The outer diameter of the sieve grid is 200mm, and the apertures are 0.18mm, 0.23mm, 0.45mm, 0.63mm, 1.25mm, 1.6mm, respectively.

The above is the detailed introduction of types of tea leaf sieve machine by Dahan Machinery. You can make a reasonable choice according to actual application requirements.
