Working Principle for Skim Milk Powder Spray Dryer
Hot air is distributed downwards with spiral method into the drying
tower after filtering and heating. Meanwhile, solution is nebulized
millions of single granule and form fog drop. Then the fog drop
contact with the hot air and most of the water flash immediately to
form the dry product. These powder and granule fall into the air
exhaust pipe at the bottom of the drying tower, collected in the

Character of Skim Milk Powder Spray Dryer
- 1). The dry speed is fast and suitable for drying thermal
sensitivity material particularly.
- 2). According to the characteristics of raw material, it can use
hot air to dry or cool air to franulate.
- 3). The evaported amount is related to characteristics of raw
Spray drying is the technology most widely used in the liquid
technology shaping and in the drying industry. The drying
technology is most suitable for producing solid powder or particle
products from liquid materials, such as: solution, emulsion,
suspension and pump- able paste states. For this reason, when the
particle size and distribution of the final products, residual
water contents, volume density and the particle shape must meet the
precise standard, spray drying is one of the most desired
After been filtered and heated the air enters into the air
distributor on the top of the dryer. The hot air enters into the
drying room in the spiral form uniformly. Passing through the
high-speed centrifugal sprayer on the top of the tower, the
material liquid will rotate and be sprayed into the extremely fine
mist liquid beads. Through very short time of contacting the heat
air, the materials can be dried into the final products. The final
products will be discharged continuously from the bottom of the
drying tower and from the cyclones. The waste gas will be
discharged from blower.
The drying speed is high when the material liquid is atomized, the
surface area of the material will increase greatly. In the hot-air
flow, 95%-98% of water can be evaporated at a moment. The time of
completing the drying is only several seconds. This is especially
suitable for drying the heat sensitive materials. Its final
products own the good uniformity, flow ability & solubility.
And the final products are high in purity and good in quality. The
production procedures are simple and the operation and control are
easy. The liquid with moisture contents of 40-60% (for special
materials, the contents might be up to 90%.)can be dried into the
powder or particle products once a time. After the drying process,
there is no need for smashing and sorting, so as to reduce the
operation procedures in the production and to enhance the product
purity. The product particle diameters, looseness and water
contents can be adjusted through changing the operation condition
within a certain range.

- YIBU conventional Spray Dryer turns liquid into powder in a highly
efficient manner. It is used within fields as diverse as the dairy,
food and chemicals industries where it has won renown for its
performance. With more than 2,500 spray dryers installed worldwide,
YIBU Dryer combines experience and cutting-edge technology into
added-value solutions for its customers.
- Designed for the specific product to be dried in compliance with a
given industry’s standards and requirements, the conventional Spray
Dryer produces a fine powder with particle sizes between 20-300 my.
It is primarily applied in the chemical industry, but it has also
proved valuable in the production of food and dairy products.
- Atomization of the concentrate takes place via either a Rotary
Atomizer or high-pressure nozzles. The drying air enters through
the air disperser at a high velocity, ensuring optimal mixing with
the atomized concentrate. Evaporation is instantaneous, taking
place as the droplets pass through the drying chamber.
- Complete control of moisture content, particle structure, particle
size distribution, solubility, and wettability, and retention of
natural aromas and flavours.
- Unbeatable performance/cost ratio Energy efficient components,
continuous and rapid drying, ease of operation and process
automation provide complete control over yield and costs.
Skim Milk Powder Spray Dryer working Steps
- 1. Atomizing: Atomize raw material into uniform fog drop through
- 2. Contact between fog drop and hot air: The hot air enters to the
drying station to contact with fog drop through air distributor,
and make a certain movement in drying station. (the movement can be
co-current flow, adverse current or mixed flow)
- 3. Drying Process: Fog drop has big surface area, and appears
obvious grades to hot air both in temperature and humidity, thus
strengthn the transmission process of plastid caloric, moisture of
fog drop is evaporated very quickly (within seconds to tens of
- Atomization: Atomizing System must ensure the spray drop
- The contacts of hot airflow and spray drop: when enough hot air
enters into drying tower, the flow way and angle have to be
considered, no matter co-current flow, adverse current or mixed
flow, must ensure the sufficient heat exchange, it is crucial.
- The angle design of the connection pipes and cones: it is very
important to select the suitable angle, here we would like to share
our experience from production of thousands of this equipments.
