50kg/h spray dryer used in the production of powdered seasoning or
condiments
Product Description:
A spray dryer can also be used in the production of powdered
seasoning or condiments. The process is similar to the one
described earlier for coffee and tea. Here's how a spray dryer can
be utilized for seasoning or condiment production:
- Preparation of the liquid mixture: The ingredients for the
seasoning or condiment, such as herbs, spices, flavorings, and
liquid components, are mixed together to form a liquid mixture.
This mixture can include water, oils, or other liquids depending on
the specific recipe.
- Atomization: The liquid mixture is pumped into the spray dryer,
where it is atomized into small droplets. This can be done using a
nozzle or rotary atomizer, similar to the process described
earlier.
- Drying: The atomized droplets enter the drying chamber of the spray
dryer, where they come into contact with a stream of hot air. The
hot air quickly evaporates the liquid component of the droplets,
leaving behind dried particles.
- Powder collection: The dried particles, now in powder form, are
collected from the bottom or cyclone separator of the spray dryer.
These particles constitute the powdered seasoning or condiment.
Features:
By utilizing a spray dryer for seasoning or condiment production,
the following benefits can be achieved:
- Improved shelf life: The low moisture content in the powdered form
helps to enhance the stability and extend the shelf life of the
seasoning or condiment.
- Homogeneous distribution: Spray drying ensures uniform drying and
particle size distribution, resulting in a consistent product with
even flavor distribution.
- Ease of handling and packaging: Powdered seasoning or condiments
are typically easier to handle, package, and distribute compared to
liquid or paste forms.
- Enhanced solubility or dispersion: Spray-dried powders often
exhibit improved solubility or dispersion characteristics, making
them easier to incorporate into various food products.
- It's important to note that the specific parameters and conditions
during spray drying, such as temperature, airflow, and nozzle
design, can be adjusted to meet the requirements of different
seasoning or condiment formulations.

The specific parameters that can be adjusted in a spray dryer for
seasoning or condiment production depend on the desired
characteristics of the final product. Here are some key parameters
that can be modified:
- Inlet temperature: The inlet temperature of the hot air stream in
the spray dryer affects the drying rate and moisture removal.
Higher temperatures can result in faster drying but may also
increase the risk of flavor or aroma loss or degradation. The
appropriate temperature range is determined based on the specific
seasoning or condiment formulation.
- Airflow rate: The airflow rate within the drying chamber affects
the residence time of the droplets, which in turn influences the
drying efficiency. Adjusting the airflow rate allows for control
over the drying kinetics and particle size distribution.
- Nozzle design and atomization: The type and design of the
atomization nozzle or rotary atomizer used in the spray dryer can
impact the droplet size and distribution. Different nozzle designs
can be employed to achieve specific particle sizes or to control
the spray pattern.
- Feed rate: The rate at which the liquid mixture is fed into the
spray dryer affects the droplet size and the overall drying
efficiency. Adjusting the feed rate allows for control over the
final particle size and production capacity.
- Residence time: The residence time of the droplets in the drying
chamber is influenced by the airflow rate, inlet temperature, and
feed rate. It is critical to ensure that the droplets have
sufficient time within the drying chamber to achieve complete
drying without excessive exposure to high temperatures.
- Particle collection system: The choice of particle collection
system, such as a cyclone separator or bag filter, can influence
the separation efficiency and the quality of the final powdered
product. The collection system should be optimized to minimize
product losses and maintain the desired particle characteristics.
It's important to note that the optimal parameter settings may vary
for different seasoning or condiment formulations, as each
formulation may have specific requirements in terms of moisture
content, particle size, and flavor stability. Process development
and optimization are typically carried out to determine the most
suitable parameter adjustments for a specific seasoning or
condiment product.
