What is the working principle of laboratory lactose stainless steel test sieve?

The working principle of the laboratory lactose stainless steel test sieve is to use the stainless steel wire mesh to screen and filter the required materials. When lactose material is placed on the sieve, through the vibration action of the motor, the material forms a continuous throwing motion on the sieve, thus realizing the classification and of the material. 

What are the advantages of the laboratory lactose stainless steel test sieve?

1. Solve the problem that lactose powder is easily affected by moisture and deterioration: Lactose powder is easily affected by moisture and deterioration, which affects the accuracy of the test results. Laboratory lactose stainless steel test sieve is corrosion-resistant and can resist the influence of humid environment. During the screening process, minimize the contact time between lactose powder and air. 

2. Deal with the problem of wide particle size distribution of lactose powder and high screening accuracy requirements: Laboratory lactose stainless steel test sieve usually requires accurate particle size analysis to meet the needs of scientific research or quality control. Stainless steel test sieve provides a variety of sieve apertures, which can achieve high-precision particle size analysis and ensure the reliability of test results.

3. Solve the problem that lactose powder is sticky and easy to agglomerate: Lactose powder has a certain viscosity and is easy to agglomerate, causing the screen to be blocked, affecting the screening efficiency and accuracy. Laboratory lactose stainless steel test sieve is smooth and not easy to adhere to lactose powder, reducing the possibility of clogging. Vibration helps to break up the agglomeration and improve the screening efficiency.

4. Dealing with the problem of electrostatic adsorption of lactose: Stainless steel itself has certain antistatic properties. The sieve frame and sieve mesh of the laboratory lactose stainless steel test sieve are made of stainless steel, which can effectively reduce the static electricity generated by friction of lactose particles during the screening process.

Technical parameters of laboratory lactose stainless steel test sieve

Sieve aperture: selected according to the lactose particle size requirements, the common aperture range is 20 mesh (850μm) to 400 mesh (38μm).

Sieve frame diameter: common diameters are 200mm, 100mm, etc., suitable for laboratory small batch sample screening.

Sieve frame height: usually about 50mm, easy to operate and clean.

Material: 304 or 316L stainless steel, corrosion-resistant and in line with food grade standards.

Number of screening layers: multiple layers of screens can be superimposed according to needs to achieve multi-level screening.

Recommended mesh size of stainless steel test sieve for lactose in laboratory

Lactose type	Particle size range(µm)	Recommended mesh size(Mesh)
Granular Lactose	250-1000	18-60
Crystalline Lactose	100-400	40-140
Fine Lactose	50-150	100-270
Micronized Lactose	10-50	325-500

If the experiment requires fine sieving of lactose powder, it is recommended to use a sieve with 200 mesh (75µm) or larger; If screening or grading larger lactose particles, a 40-100 mesh sieve can be selected. Laboratories are usually equipped with multiple mesh test sieves to meet the requirements of different particle size detection.

Recommended mesh number of laboratory lactose stainless steel test sieve

Coarse screening: If a coarse screening is required to remove larger particles, a test sieve with a lower mesh number, such as 20 mesh or 40 mesh, can be selected.

General screening: For general particle analysis and screening, it is generally recommended to select a test sieve between 60 mesh and 100 mesh.

Fine screening: If a more detailed screening of lactose particles is required to obtain more accurate particle size distribution data, a test sieve with a mesh size of 120 or more can be selected, even up to 200 mesh.

Multi-stage screening: Sometimes it is also possible to consider using multi-stage screening, combining test sieves with different mesh numbers for multi-stage screening to obtain more comprehensive particle distribution information.
