Vitamin powder test sieve

What is a vitamin powder test sieve?

 

Vitamin powder test sieves usually refer to equipment used to sieve vitamin powders in laboratories or small-scale tests, mainly for analyzing the particle size distribution of vitamin powders, quality control or research and development purposes.

Vitamin Powder Characteristics and Sieving Requirements

Particle Size: Vitamin powder particle size is usually between 10-500μm, depending on the production process.

Properties: Hygroscopic, medium fluidity, may be slightly sticky or agglomerate.

Requirements: The test sieve must ensure high-precision classification, avoid contamination, and meet food or pharmaceutical grade hygiene standards.

Working principle of vitamin powder test sieve

The test sieve is based on the principle of vibration screening and consists of multiple layers of standard sieves (different mesh sizes), sieve frames and vibration devices.

Process:

①Place the vitamin powder sample on the top sieve.

②The vibration motor drives the sieve frame to produce horizontal and vertical vibrations, and the vitamin powder moves on the sieve.

③The vitamin powder particles smaller than the sieve holes pass through layer by layer and are finally collected in each layer of sieve according to the particle size distribution.

What are the advantages of vitamin powder test sieve?

1. Particle size analysis and fluidity improvement

The uneven particle size distribution of vitamin powder will lead to poor fluidity, and problems such as agglomeration and bridging are prone to occur during transportation. The vitamin powder test sieve can accurately measure the particle size distribution of vitamin powder and understand the proportion of particles of different particle sizes.

2. Quality control and uniformity assurance

The uneven particle size distribution of vitamin powder will lead to uneven mixing, affecting the content and stability of the active ingredients of the product. Vitamin powder test sieve can detect the particle size consistency of different batches of vitamin powder to ensure stable product quality.

3. Remove impurities and improve product purity

Vitamin powder test sieve can remove foreign matter, coarse particles and uncrushed agglomerates, improve the purity of vitamin powder, and can also meet the strict requirements of the pharmaceutical and food industries for powder fineness and purity.

4. Prevent agglomeration and clogging

Vitamin powder test sieve can effectively reduce powder adhesion and adhesion and prevent screen clogging. Operation in a low humidity environment, combined with anti-static treatment, reduces the risk of powder agglomeration.

Mesh size of vitamin powder test sieve

Coarser particles (40-80 mesh): suitable for vitamin powders that require better fluidity, reduce dust flying, and facilitate subsequent processing.

Medium particles (100-200 mesh): suitable for most vitamin powders, such as raw materials before tablets and capsules are filled. Improve mixing uniformity and ensure stable product quality.

Ultrafine particles (200-400 mesh): suitable for special purposes, such as instant preparations, spray-dried powders, to improve bioavailability and absorption effects. Suitable for drugs and functional foods that require strict control of particle size distribution.

Relationship between mesh number and sieve aperture

40 mesh	425μm	coarse powder  (150-500 μm)	applicable to vitamin powder with larger particles, such as some crystalline or granular vitamin C, B vitamins, etc.
60 mesh	250μm	medium powder (44-150 μm)	applicable to coarser powder, ensuring certain fluidity and reducing dust
80 mesh	180μm	medium powder (44-150 μm)	applicable to conventional vitamin powder, such as powder before tablet and capsule filling
100 mesh	150μm	fine powder  (10-44 μm)	applicable to most vitamin powders, ensuring particle uniformity and improving mixing uniformity
120 mesh	125μm	fine powder (10-44 μm)	Sieving of high-precision vitamin powder
200 mesh	75μm	Ultrafine powder (0.5-10 μm)	Suitable for ultrafine powder, such as micronized vitamin A, D, E and other fat-soluble vitamins
325 mesh	45μm	Ultrafine powder (0.5-10 μm)	Sieving of ultrafine vitamin powder.
400 mesh	38μm	Ultrafine powder (<0.5 μm)	Suitable for ultrafine powder, meeting high-precision requirements

Application of vitamin powder test sieve

Vitamin powder test sieve is widely used in food, pharmaceutical, health care products and agriculture industries. It can not only be used for product quality control, but also for production process optimization and new product development. Through the test sieve, the particle size of vitamin powder can be accurately controlled to ensure the quality and stability of the product.
