ZLG Spray Drying Machine For Chinese Traditional Medicine Extract
(HERB EXTRACT Spray dryer ) (Atomizer Dryer)( Spray drying machine
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
The Herb Extract Spray Dryers have been designed using standard
modules that incorporate all the required features necessary for
cGMP production. The philosophy is that standardized modules are
built together to meet the requirement for a specific duty. All
plants are designed and configured to meet individual User
The machine adopts full seal form. It is equipped with three grades
of filter. The filtered air is one hundred thousand grades. The
cooling device of wall is installed at the cylinder body. It makes
the wall temperature less than 80˚C. Air sweeping device is
installed inside the drying tower. The product will not be burnt or
deteriorated even stays on the way. The collection rate of powder
is raised greatly. Moreover will not cause medicine mixed or wall
Basic principle: high-speed centrifuge atomizing for the extract of
traditional Chinese medicine is an application of centrifuge
atomizing technique. It is an high-speed atomizing dryer. The
following problems are solved.
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.
