Detailed description
product description:
Airflow spray drying processes required process can be divided
into two types, one is the jet, which nozzle is provided at the top of
the drying tower and hot air atomized liquid material from the stream
down and complete the drying process, for and it has a viscosity greater
drying certain sensitive materials; the second nozzle is provided in
the bottom of the drying tower and hot air atomized liquid material
together with the completion of the drying process from the bottom up,
good heat resistance suitable for the material dry, traditional
small-scale dry water reducer original have adopted this approach.
Airflow atomizer spray dryer, also called air-nozzles, nozzle
structure is generally simple, low viscosity and high viscosity of the
material can be atomized liquid material, the use of a wider scope, the
resulting smaller particles, typically about 5 -30 microns, operating
flexibility. But its disadvantages are also obvious, that is, the power
consumption of compressed air for atomization of a larger, mainly for
high viscosity fluid or material larger molecular weight organic
material liquid spray dried.
Airflow nozzle according
to the structure can be divided into three two-fluid and fluid, wherein
the second fluid can be divided into an outer recirculation and mixing
within two.
working principle:
Clean air into the heated drying tower, the tower using hot air
in the second fluid (or three-fluid) liquid feed nozzle variety of
material into tiny droplets, and hot air for fast heat exchange fluid
evaporated feed water (or solvent), and with the hot air is discharged
to obtain a powdery product.
Features:
1, especially for viscous, pasty, pasty material and good effect, other devices can not be replaced.
2, experimental variety, wide application of low-temperature drying.
3, the nozzle structure, easy maintenance, low operating costs.
4, good operating environment, dust emissions to meet national standards.
5, drying superior product quality, uniform size, mobility, and final moisture evenly.
Applications:
Food: amino
acids, spices, protein, milk powder, blood meal, soy sauce powder, tea
powder, glucose, potassium sorbate, flavors and spices.
Medicine: vitamins, medicine and antibiotics.
Chemical products: disperse
dyes, reactive dyes, organic catalysts, white carbon black, washing
powder, potassium carbonate, potassium phosphate, all kinds of waste and
so on.
