Spray Nozzles, Nozzles, Air Spray Nozzles, Spray Manufacturer … Ed_2 Air... · 2018-09-26 · An air atomizing spray nozzles can work on three principles as below : 1) Pressure

Air atomizing spray nozzles produces fine mist spray with the help

of compressed air, liquid breaks into small droplets as air provides

sharing effects on liquid droplets. Various spray pattern are

available, there are categorized into Flat and Round spray

patterns. The droplet size can be adjusted by flow adjustment of

compressed air. Air atomizing nozzles are divided into two types

Internal and External mix air atomizing nozzles. Those are available

in various metals.

An air atomizing spray nozzles can work on three principles

as below :

1) Pressure Principle

2) SIPHON Principle

3) Gravity Head Principle

3) Gravity head Principle

Gravitational head of liquid is utilised to feed liquid

to the spray nozzle, suitable where pump or

pressurized container of liquid is not available.

1) Pressure Principle

Liquid is supplied in pressurised form with the help of pump or pressurised container, separate compressed air is needed

2) Siphon Principle

Siphon principle is utilised to lift liquid from certain

height from spray nozzle, suitable where pump or

pressurised container of liquid is not available.

Choice of spray NozzlesEach spray set-ups consists of an air cap and liquid cap which provide a specific spray pattern capacity and coverage performance

Inside Body MixingLiquid and air streams meet within nozzle and are mixed together and expelled through the same orifice. This internal mixing means the streams are not independent; a change in air flow will affect the liquid flow. This makes precise metering of the liquid more difficult than with an External Mix Set-up. Internal Mix set-up are able to produce the finest atomization of any of the XA set-ups, but they are generally not suitable for use with liquids which have a viscosity that is above 200 centipoise.

Out Side Body Mixing The air and liquid streams exit the nozzle independently and are combined and mixed outside of the nozzles. Because there is no connection between the air and liquid lines within the nozzles, the air and liquid flow rates can be controlled independently, allowing precise metering of the liquid. The atomization can be controlled by adjusting the air flow rate more air produces finer atomization. In most cases these set-up do not atomize as finely as Internal Mix Set-ups.

External Mix Set-up may be used with liquid having a viscosity above 200 centipoise and for abrasive suspensions. Spraytech provides Engineering guidance for spraying high viscosity liquids.

Today many solid pharmaceutical dosage mediums are produced with coatings, either on the external surface of tablets, or on materials dispensed within gelatine capsules.

Coating serves a number of purposes right from protecting stomach lining from aggressive drugs to protecting the tablet from stomach acids.It also helps in maintaining the shape of the tablet and thus can offer a delayed release of the medication.

But for good results, a better coating medium is required. And the same can be fulfilled by Tablet coating spray nozzles.

General purposes of tablet coating

• Covers u npleasant taste, colour and odour• Chemical a nd physical protection from environment • To control the release of drug with enteric coating• It protects drug from gastric surrounding of stomach • Provide w ay to identify the drug and improves appearance

Results of bad coating

• Sticking or picking • Roughness • Twinning • Peeling • Cracking

Tablet Coating Process

Granulation With RMG / HSG

Also known as wet granulation process. material is loaded into bowl having agitator and chopper and mixed rigorously then binder material is sprayed from top and granules are formed.

Good quality granules are foundation for good quality tablet.

Various liquid blinders are used for wet granulation.

Spraying binder over bulk material could reduce wet granulation cycle time and increase productivity.

Example of Bad Tablet Coating

It is the process to apply coating material on external surface of tablets to enhance its efficiency and properties.

Fluid bed process consists of following applications :

1. Drying Process o f e xtracting moisture from solid bulk material by making it fluidized with high flow blow of air, so moisture is removed

homogeneously and all over surface of every single particle.

2. Granulation/ Agglomeration P o w d er particles of bulk material bonded by liquid fine spray. Liquid could be water or an organic solvent and the powder

material will be mixed together. Agglomerate has less strength of particle bond.

3. Coating Fluidized p a r ticles are coated with spray of coating material which enhances. coating film must be very uniform over the particle

surface.

4. Ta ngential Coating Centrifugal m o tion is used for making spherical pallets, at the same time particles are bonded by binder liquid. layering also can

be done in same way.

Spraytech's RC Series tablet coating spray nozzle are specially designed to meet GMP requirements where surface texture plays very important role.

The unique Air Cap design makes it Anti Bearding and keeps coating process shutdown free, thus higher production ratio and quality requirements are achieved.

RC series spray nozzle is a compact device incorporating of independent controls for Liquid, Atomizing Air and Fan Air for fine tuning of spray capacity, droplet size and spray patterns. It is available in wide variety of spray setups that give a complete selection of flow rate and flat spray patterns.

R series spray nozzles are externally mix nozzles. This means the liquid and air are mixed outside of air cap to produce complete atomized spray.

The liquid atomization is controlled by varying atomizing air and fan air pressures without changing liquid flow rates. The flat spray pattern is controlled by varying the fan air pressure in conjunction with the atomizing air. This is effective for high viscosity liquids, coatings and suspensions.

Tablet coating spray nozzle features a cylinder for controlled "on-off" operation. The cylinder controls a liquid clean-out/ Shut-off needle which also cleans the liquid orifice.

DESIGN FEATURES

1. Separate atomizing and fan air lines for complete control.

2. Provides variable coverage and fine control of drop size

without affecting liquid flow rates.

3. Higher atomizing air pressure yields fine droplet size.

4. Higher fan air pressure yields broader patterns.

5. Non clogging and anti - bearding design

The R Series coating Spray Nozzle are a compact, precision nozzles. Incorporating independent controls of liquid atomizing air and fan air for fine tuning of spray capacity droplet size and spray patterns. It is available in a wide variety of spray Set-ups that give a complete selection of flow rates and flat spray patterns.
