Pilotech mini spray dryer is the latest trend and hottest deal in the market even as you read this post. But again, it has a relatively long age behind it. Yet, it controls the market.

Do you seek to know what Pilotech mini spray dryers feature? Then let’s begin with 20 years production history that has made Pilotech mini spray dryer the best and most sought-after product in the market.

Pilotech Mini Spray Dryer Production History 

The Pilotech mini spray dryer is an outcome of about two decades of research and solution delivery. The product is manufactured by Shanghai-based technology company, Pilotech Instrument and Equipment Co., Ltd, one of the world’s leading solution providers in the laboratory technology industry. The company technically started operations in 2005.

The company is popular for its high-quality products, incredible internal and external quality control, and state-of-the-art R &D environment. The company has been a strong partner to more than 3500 product users and clients.

The vision is to reel out value-added budget-friendly lab spray drying equipment. The company distinguishes itself from other manufacturers of mini spray dryer by delivering products with out-of-the-world solutions.

Working principle of Pilotech Mini spray dryer

Pilotech mini spray dryer has a very simple mechanism by which it operates. On the equipment is a menu-driven microprocessor regulator which is responsible for selecting inlet temperature. The inlet air temperature for the YC-018 laboratory spray dryer ranges from 110 to 350 °C. The regulator also allows you to pick airflow as well as de-blocker frequency.

Once it selects the operations, the self-priming positive displacement pump (otherwise called a roller pump) acts on the diameter jet and then releases fluid sample from a container into the main chamber.

While this is going on, the compressor pumps air into the outer duct of the diameter fluid jet. The result of the operations of the roller pump and the compressor is the release of a finely atomized liquid spray into the drying chamber.

The dryer begins its dehydrating process in the drying chamber. High-temperature air is blown into the chamber to disperse all forms of vapour left in the atomized spray. A cyclone separates the free-flowing solid particles from the exhaust airflow, gathering together the solid materials through the sample collection bottle.

Meanwhile, the exhaust airflow is directed towards the atmosphere or into an extraction system through a flexible hose, usually with a diameter of 60 mm.

Differences and advantages between Mini spray dryer and vacuum dryer

Vacuum drying machine is the kind of dryer used for drying substances which tend to absorb moisture and vapour from the air. They are also used for thermally sensitive materials. The principle of operating vacuum dryer is forming a vacuum to drop the pressure in the chamber just below the vapor pressure of the water. The result causes the water to boil, thus increasing the rate at which the product dries.


-It conserves a lot of energy as less energy is required for drying.

-It is cost-effective, reducing costs on storage and sale.

-It works faster than other drying techniques.

-It cuts down on processing times.

-It is a less damaging method.

However, the mini spray drying process is not as fast as the vacuum process.

Differences and advantages between Mini spray dryer and Mini freeze drying

Mini freeze drying, technically called lyophilization, is a process of drying in which you freeze material and then decrease the surrounding pressure to make the frozen water contained in the material to change from solid state to the gaseous state. This process is used mainly to preserve perishable goods or make them safe for long-distance conveyance.

However, the mini spray dryer is used for spry drying organic solvents and aqueous solution. It cannot be used for preserving food.

There are three stages of mini freeing dehydration undergoes, namely, the


  • It is used to preserve perishable goods
  • It is economical in terms of resources and time

Mini Spray Dryer: The Ultimate FAQs Guide

If you have any question about mini spray dryer, you will find the answer right here.

This guide covers everything about mini spray dryers such as parts, working principle, cleaning process, nozzle types, specification, and many more.

So, if you want to be an expert in mini spray dryers, keep reading.

What is a Mini Spray Dryer?

This is a machine you can use to convert slurry, low viscosity paste, or liquid into free-flowing powder in single unit operation.

It is a piece of continual processing equipment that comes in a wide range of configurations.

Spray dryer helps in drying a material quicker compared to other types of industrial drying machines.

They find application in nearly every sector, including food and beverages, paint and pigments, mining and minerals, and pharmaceutical industries.

What are the Differences Between Mini Spray Dryer and Freeze Dryer?

Here is a comparison of Freeze dryer vs. mini spray dryer in terms of:

Freeze dryer

Freeze dryer

Drying Process

In a freeze drying technique, the drying process entails the initial freezing of material before placing it in a vacuum.

The freezing is often performed in a controlled fashion to manipulate the structure of the ice crystal.

Primary drying through sublimation occurs at this stage to eliminate the unbound water.

Next is secondary drying, which sublimes the bound water, transforming the material to your specified residual moisture level.

This stage requires more energy since the target is bound instead of being unbound.

This is because of the operation of increasing shelf temperature to +20 degrees Celsius, in addition to low atmospheric pressure.

The goal is to bypass the liquid stage and transform ice straight into water vapor.

Conversely, a spray drying process involves a more straightforward and quicker process.

Spray drying entails a single-step process that transforms a liquid emulsion into dry powder.

The spray drying machine atomizes the solution into fine droplets that are immediately dried utilizing warm gas in a big chamber.


The temperature of products during primary drying in a freeze dryer is typically below 0 degrees Celsius.

Whereas in secondary drying, the temperature falls between 20 to 30 degrees Celsius.

On the other hand, product temperatures in the mini spray dryer are usually above 80 degrees Celsius.

Quality of the Final Product

Moreover, the main advantage of a freeze dryer is its robust product quality.

Accurate regulation of low processing temperatures reduces any threat to the intrinsic characteristics of products.

Freeze dryers avoid eutectic melt, surpassing glass transition temperature and collapse, which results in the highest quality products.

However, mini spray dryers can subject products to shear stress in addition to the high temperature required during processing.

This has the potential of destabilizing compounds like proteins and compromise product properties, which ultimately reduces the quality of products.

Efficiency and Cost

The cost of mini spray dryer is comparatively lower than that of freeze dryer, which makes it a better option in certain industries.

Furthermore, having the potential for larger throughput, spray dryers are assumed as continuous process equipment, different from batch format of freeze dryers.

However, though the upfront cost of mini spray dryers is often lower.

This is not usually the situation for more complex formulations.

Products that need multiple layers of coating will have to go through multiple processes of coating.

This can require a lot of time and cost, making freeze drying a more cost-effective option for some formulations.

Which are the Main Features of Mini Spray dryer?

Here are the main properties of mini spray dryer:

Compact Size

This type of drying equipment comes in small size, ensuring easy portability coupled with efficiency and cost-effectiveness.

Multiple Functions

Most modern spray dryers feature the ability to serve a number of purposes.

For example, you can find a single mini spray dryer for organic solvents, water formulations, aqueous solutions, dyestuffs, and pharmaceuticals.

Moreover, the machine can function as a spray drying granulator and cyclone spray dryer.


All functions and control keys on your spray dryer are simple to display and manipulate to suit your need.

You can scale up the device to pilot or industrial level as much as you want.

The particle size has an adjustable scale range from 1-25microns.

Similarly, the equipment also prides itself on a high level of flexibility when you look at the different cylinder linear measures.

· Digital Control System

Most mini spray dryers come with programmable logic controllers (PLCs) as their control system.

Which are the Different Types of Mini Spray dryers?

The most common types of spray dryer include:

Spray dryer system

Spray dryer system

Single Effect Spray Dryer

This is the most popular type of mini spray dryer.

The equipment has one source of drying gas at the chamber top.

Typically the air is injected in similar direction (co-current) to that of sprayed liquid.

It produces fine powder with poor flow and generates a lot of dust.

Multiple Effect Spray Dryers

A multi-effect spray dryer is a modern spray dryer type developed to overcome the poor powder flow and excess dust.

The drying machine applies two stages of drying materials, unlike single effect mini spray dryer.

The first is located at the top and the second has an integrated static bed at the chamber’s base.

Besides, the bed offers a humid condition, which causes clumping of smaller particles, producing more consistent particle sizes.

The sizes span from 100 to 300 μm.

This type of mini spray dryer produces free-flowing powder because ofits larger size of particle.

You can recycle the fine powder produced by the first phase in continual flow above the chamber. This takes place about the sprayed liquid.

Alternatively, you can recycle the powder within the integrated fluidized bed.

An exterior vibrating fluidized bed can finalize the drying of the products.

Multiple effect spray dryer can inject the hot drying air as a co-current, in one direction with the sprayed liquid atomizer.

You can also inject it counter-current, where the flow of hot air is reverse of the atomizer flow.

In co-current flow, the particles take less time within the mini spray dryer and particle separator (usually cyclone equipment).

However, the particles take more time within the system and are normally linked with a fluidized bed mechanism in counter-current flow.

Therefore, co-current flow facilitates efficient operation of this mini spray dryer type.

Tall-form Spray Dryer

The spray drying machine utilizes a nozzle as the feed atomizer.

It is referred so because of the comparatively narrow nozzle spray angle and relative droplets velocity.

This needs a tall drying chamber having a proportionately small diameter to give adequate residence time to attain drying.

Centrifugal Spray Dryer

Shorter and fatter, this type of mini spray dryer utilizes rotary disk atomizers to produce the spray.

It has a flat spray angle with a broad spray pattern, thus the broad short and broad diameter tower.

What are the Main Parts of Mini Spray Dryer?

The basic components of spray dryer consist of:

Spray dryer flow diagram

Spray dryer flow diagram

Heating System

The heating system of mini spray dryer applies either direct or indirect heating technique.

With an indirect technique, the air has direct contact with the source of heating.

Nonetheless, in indirect technique, a heat exchanger indirectly heats the air.

The most important parameters in this method are temperature, airflow rate, and thermo-physical properties.

Spray Nozzle/Atomizer

This component of mini spray dryer helps in the optimization of the evaporation process.

Here is where you convert the liquid emulsion to fine droplets, assisting in the formation of a product having desirable features.

It uses different nozzles depending on the consumed energy for droplets production.

Drying Tower Chamber

The machine performs the spray drying process within the drying chamber.

This is where you remove moisture from the material by spraying it in the form of small droplets into heated air.

Dimensions and size of the drying chamber rely on the material type and type of distribution of the inlet hot air and feed.

Moreover, the feed rate and type of atomizer also determine its size and dimensions.

Powder Recovery Systems

Using centrifugal force, a cyclonic separating system segregates the tiny particles exiting the spray dryer from the heated air.

Process Control Systems

Most types of spray drying machines use a programmable logic controller (PLCs) as their control system.

Which are the Types of Nozzles used in Mini Spray Dryer?

Here are the different nozzle types you can use in the mini spray drying machine:

Nozzles in spary dryer

Nozzles in spray dryers

· Pressure Nozzles

Pressure nozzles working principle relies on conversion of liquid pressure energy to the flowing liquid kinetic energy.

It separates the liquid layers from one another because of their physical characteristics and air friction effect.

The change in pressure is the controlling parameter of the nozzle properties and feeding rate.

Also, the mean size of the nozzle is as well directly proportionate to the liquid viscosity and feeding rate.

Using pressure nozzles will help you reduce sedimentation within the dryer chamber.

However, it forms coarse powder particles with high bulk density.

· Centrifugal Nozzles

Here, centrifugal force moves the liquid towards a rotary disk center where the disk blades form the droplets.

The size of the particle is inversely proportionate to the rotary velocity and centrifuge disk diameter.

However, the particle size has direct proportionality to the density, surface tension, and viscosity of the material.

This type of nozzle for the mini spray dryer does result in clogging and fouling issues.

Therefore, it facilitates the manufacturing of high viscosity products with high crystals amount.

Pneumatic Nozzles

In these nozzles, you atomize the liquid formulation through high air velocity resulting inthe creation of frictional forces.

These forces help in the disintegration of the liquid to tiny droplets, which takes place in two phases.

The first phase does the liquid feed conversion to coarse droplets.

The second phase entails the coarse droplets conversion to tiny droplets.

Rheological features of feed and air like viscosity, surface tension, and density dictates the final quality of your product.

This type of nozzle for spray drying machine experiences clogging and fouling issues.

What are the Benefits of Mini Spray Dryer?

Here are some of the key advantages of spray dryers:

  • Generates powder particles having controllable moisture content, form, size, and shape regardless of heat sensitivity and capacity of the spray dryer.
  • The drying machine can have a variety of production rates and offers extensive design flexibility.

How Does Mini Spray Dryer Work?

The working principle of a spray dryer is straightforward.

The spray drying machine has a menu-driven microprocessor controller responsible for choosing inlet temperature.

Typically, the inlet air temperature spans from 110 to 350 degrees Celsius.

The controller as well enables you to select de-blocker frequency and airflow.


After configuring the parameters of the spray drying process, the roller pump initiates the diameter jet.

The action injects fluid into the primary chamber from a container.

The rotary atomizer or nozzle converts the liquid formulation into tiny liquid droplets.

This is the stage where you develop the required final product qualities like size and viscosity of particle.


As atomization continues, the compressor injects air into the external diameter fluid jet duct.

The combined action of the compressor and roller pump injects into the drying compartment a fine-grained liquid spray.

It is in the drying chamber where the mini spray dryer starts the dehydrating process.

The system disperses all kinds of vapor remaining within the atomized spray by blowing hot air into the chamber.

This dries the droplets from the atomizer into a powder that is easy to pack and transport.

You can control the final powder moisture content by fine-tuning the hot air temperature.


The process of recovering powder from the exhaust air takes only a few seconds.

You can perform the recovery by using a cyclone or bag filter.

A cyclone segregates the free-flowing solid grain from the exhaust air.

Ultimately, the sample collection container of the mini spray dryer gathers the solid powder.

Moreover, a flexible hose (typically with 60 mm diameter) directs the exhaust gas into an extraction mechanism or atmosphere.
