What is a protein powder sieving machine?

The protein powder sieving machine is a device specially used for grading and screening protein powder. It is designed to separate protein powder particles of different particle sizes by vibration or rotation to ensure the uniformity and purity of the product. Protein powder is usually delicate, easy to agglomerate and has different particle sizes. Therefore, the sieving machine needs to have anti-blocking nets, high grading accuracy and the ability to adapt to fine powder screening.

According to the particle size distribution of protein powder, screening is usually divided into a multi-layer screen combination, and the commonly used screen mesh is mostly 80 mesh to 200 mesh (corresponding to about 180 microns to 75 microns) to meet the fineness requirements of different products. Coarser protein powder particles can be pre-screened with a lower mesh screen, while products with higher fineness are finely screened with a finer mesh screen.

Reasonable screening grade design can not only improve the purity of protein powder, but also effectively remove impurities and agglomerates to ensure the quality of subsequent processing or direct consumption. Protein powder sieving machines are widely used in the production process of various protein powders such as whey protein and soy protein, and are important equipment to ensure the quality and performance of protein powder products.

How to choose a protein powder screening machine?

When choosing a protein powder screening machine, it is necessary to consider factors such as the material characteristics, screening requirements and output requirements of the protein powder. The following analysis of four common screening machine types, ultrasonic vibrating screen, linear vibrating screen, circular vibrating screen and drum screen, helps to determine which is more suitable for specific protein powder materials and their screening sizes.

1. Ultrasonic vibrating screen

The ultrasonic vibrating screen activates the screen through high-frequency ultrasonic vibration, reduces the adhesion and blocking of powder particles, and improves the screening efficiency. It is especially suitable for fine powder and materials that are easy to agglomerate.

Suitable for protein powder materials: protein powder with high fineness and fine particles; protein powder that is easy to absorb moisture and agglomerate, such as whey protein powder, isolated whey protein, etc., which have strict requirements on screen blocking

Screening size range: Generally, fine powders below 50 mesh (about 300 microns) can be screened, and even below 10 microns can be screened.

2. Linear vibrating screen

The linear vibrating screen generates horizontal linear vibration through the motor exciter, and the material moves linearly along the screen surface for screening. It has a simple structure and a large screening amount.

Suitable for protein powder materials: protein powder with medium particle size and uniform particles; protein powder with relatively dry particles and not easy to agglomerate; suitable for large-scale screening needs and occasions requiring high output

Screening size range: the general screening range is between 20-200 mesh (about 850 microns to 75 microns).

3. Circular vibrating screen

The circular vibrating screen generates multi-directional vibrations through the eccentric block, and the material moves in a circular motion on the screen, with uniform screening effect, suitable for materials of various particle sizes.

Suitable for protein powder materials: protein powder with a wide particle size distribution and a small amount of larger particles; occasions with medium screening accuracy requirements and moderate output; suitable for pre-screening of protein powder containing a small amount of impurities or lumps

Screening size range: commonly used screening sizes are 20 mesh to 200 mesh (about 850 microns to 75 microns).

4. Drum screen

The drum screen is screened by rotating the screen drum, suitable for materials with uniform particle size and not easy to stick together, usually used for screening larger particle size materials.

Suitable for protein powder materials: protein powder with larger particle size, uniform particles and good fluidity; coarse screening or pre-screening stage to remove large particle impurities

Screening size range: usually suitable for screening particles larger than 3mm, with larger specific sizes.

Comprehensive recommendations

Summary of selection points

Material fineness and fluidity: Ultrasonic vibrating screen is preferred for fine powder and materials that are easy to block the screen; linear vibrating screen or circular vibrating screen can be selected for medium-sized particle materials; drum screen is used for coarse particle materials.

Production requirements: Linear vibrating screen or drum screen is recommended for large production; ultrasonic screen is selected when high precision and fineness requirements are required.

Screening accuracy: Ultrasonic vibrating screen is the first choice for fine powder and fine screening.
