Animal blood High Speed centrifugal Spray Dryer with touch screen
Application
Animal blood High Speed centrifugal Spray Dryer with touch
screen is widely used in the liquid technology shaping and in
the drying industry. It is most suitable for producing powdered or
granular solid products from liquid state materials such as
solution, emulsion, suspension, and pumpable pastes. So, when the
size distribution, residual water contents, stacking density and
shape of final products must reach a certain precision standard,
the spray drying is one of the most desired technologies.
Principle of work
Animal blood High Speed centrifugal Spray Dryer with touch
screen is gas-liquid co-current flow drying equipment, using high-speed
centrifugal atomizer, the liquid will be atomized into fine
droplets, then mix with the hot air from the distributor in the
dryer, heat and mass transfer exchanges rapidly during the mixing
process. In a very short period of time the liquid become dry
powdered products. Production control and product quality control
is convenient and reliable. It is widely used in the drying
production of different types of liquids materials.
Features
1.Fine droplets are dried in the drying camber by supplying hot air
through the inlet.
2.The surface of the liquid drop is dried immediately to form a
tough shell.
3.Further the liquid inside must escape by diffusing through the
shell at a particular rate.
4.At the same time heat transfer from outside to inside takes place
at a rate greater than liquid diffusion rate.
5.As a result heat inside mounts up which allows the liquid to
evaporates at faster rate.

Spray Drying Stages
1. Atomizing: by atomizer, feed liquid is dispersed into even fog
drops.
2. Contact of fog drops and hot air: through air distributor, hot
air enters into drying chamber, fully mixing with fog drops and
moves at a certain rule(the contact way can be co-current flow,
adverse current, mixed flow)
3. Drying process: fog drops has big surface area, and appears
obvious ”grades” to hot air both in temperature and humidity, thus
strengthen the transmission process of “plastid caloric” moisture
of fog drops is evaporated very quick(within seconds to tens of
seconds)
