Powder to granule: How dry granulation machines are changing the pharmaceutical industry?

Pubdate: 2025-03-21

1、 The Powder to Particle Challenge in the Pharmaceutical Industry

In the pharmaceutical industry, converting powdered raw materials into granules is a key step in producing solid formulations such as tablets and capsules. However, traditional wet granulation processes face many challenges:

High energy consumption: requires additional drying steps and consumes a large amount of energy.

Pollution risk: The use of liquid adhesives may introduce pollutants, affecting the quality of drugs.

Complex process: unfriendly to heat sensitive or easily hydrolyzed pharmaceutical raw materials.

The emergence of dry granulation machines provides efficient solutions to these challenges.

2、 Working principle of dry granulation machine

The dry granulation machine directly compresses powder raw materials into granules through mechanical pressure, without the need to add liquid binders. The workflow includes the following steps:

Raw material pretreatment

Mix the drug powder and excipients evenly to ensure ingredient consistency.

press forming

Press the powder into dense thin sheets or strips using high-pressure rollers.

Crushing and granulation

Crush the pressed thin sheets or strips into particles of the desired size.

Screening and collection

Separate the particles that meet the requirements through a sieve and collect them.

3、 How does the dry granulation machine change the pharmaceutical industry?

(1).  Increase productivity

The dry granulation machine does not require drying steps, significantly shortening the production cycle.

The continuous production mode has increased production capacity and met the demand for large-scale drug production.

(2).  Improving drug quality

High particle density and good flowability improve the uniformity and stability of tablets or capsules.

No liquid adhesive is required, avoiding degradation or chemical reactions of drug components.

(3).  lower production cost

Reducing energy consumption and raw material waste has lowered production costs.

Equipment maintenance is simple, reducing operating costs.

(4).  Environmental Protection and Safety

No wastewater discharge, reducing environmental pollution.

Sealed design prevents dust from flying and ensures the safety of operators.

(5).  Adapt to diverse needs

Suitable for various pharmaceutical raw materials, including drugs that are heat sensitive, easily hydrolyzed, or insoluble.

Can produce particles of different particle sizes to meet diverse formulation needs.

4、 Application case of dry granulation machine

tablet production

Intermediate particles used for preparing tablets to improve the compressibility and flowability of drugs.

Capsule filling

Make the medication into granules and fill them into capsules to ensure accurate dosage.

Traditional Chinese Medicine Preparations

Suitable for granulation of traditional Chinese medicine powder, improving its fluidity and solubility.

Functional drugs

Used for preparing drug particles in special dosage forms such as sustained-release and controlled release.


5、 The future development trend of dry granulation machine

Intelligent
