Self developed spray gun

Pharmaceutical coating machine bottom sealing (spray gun)

Self developed spray gunFunction: It is an important component of the coating machine, and its main task is to pre treat the tablet before coating, that is, to apply a thin layer of bottom solution on the surface of the tablet. This preliminary coating not only protects the tablets from potential wear and impact during subsequent coating processes, but also enhances the adhesion of the top coating material, ensuring the uniformity and integrity of the coating layer.

Improving coating quality: By using a spray gun, a uniform bottom layer can be formed on the surface of the tablet, which is crucial for ensuring the uniformity of the top coating.

Enhance coating adhesion: A suitable bottom layer can enhance the adhesion between the top coating and the tablet body, preventing the coating from falling off during use.

Protecting pills: Coating the bottom layer before coating helps to protect the physical stability of the pills inside the coating machine, especially for fragile or sensitive drugs.

Control drug release: Its use can also affect the release characteristics of drugs, as it alters the initial conditions on the drug surface.

Design and technical characteristics of self-developed spray gun

Design usually focuses on achieving precise spraying effects, allowing the underlying liquid to be evenly distributed on the surface of the tablet. Its technical features include:

Precise nozzle design to ensure consistency and repeatability of spraying.

Adjustable spray mode, suitable for tablets of different shapes and sizes.

Constructed with corrosion-resistant materials to accommodate various types of underlying liquids.

Easy to clean and maintain to ensure production continuity and high efficiency.

Considerations in practical applications

In pharmaceutical production, multiple factors need to be considered when using:

Selection of bottom liquid: Choose the appropriate bottom liquid based on the characteristics of the drug and the desired coating effect.

Optimization of spraying parameters: including spraying pressure, spraying speed, nozzle distance, etc., to ensure the best spraying effect.

Characteristics of pills: Different pills may have different requirements for the underlying coating.

Quality control: Continuously monitor and test the quality of the sealing process to ensure consistency of each batch of products.
