The Mini Inert loop spray dryer YC-501
Is the result of 15 years continuous development,is your choice for the quick and gentle drying to powder of aqueous and organic solutions. The impressive features of the Spray Dryer include its efficient performance with very short set-up times, an effective integrated nozzle cleaning mechanism and a high
degree of flexibility thanks to the different cylinder geometries.

PRINCIPLE:

To safety spray dry inflammable solvent, a new operating principle is employed with uses a combination of the spray dryer YC-500 and the inert loop YC-501 to provide a closed loop circulation under inert conditions. The absence of oxygen prevents the formation of a ignitable mixture. At the same time, the solvent contained in the gas stream is cooled and consequently condensed. The regenerated flow is then returned again to the spray dryer.

SAFETY:

YC-501 inert loop spray dryer features good safety and easy operations as it adopts closed cycle of nitrogen (or other inert gas), a safe gas, to keep the entire system in a closed state, and on-line monitoring of oxygen concentration such that the system would power off automatically and alarm when the oxygen concentration has reached 2.5% (which can be the user as needed).

The combination of closed nitrogen cycle and full solvent recovery allows treatment of flammable and toxic solvents and drying of readily oxidizable material. In addition, the low boiling points of organic solvents allow low temperature drying of the material subject to heat denaturation.

SOLUTION TO DIFFICULTY TO DRY ORGANIC SOLVENTS:

hile organic solvents are generally flammable and explosive, an explosion-proof, inter lopp spray dryer allows the materials to circulate in a closed drying system and prevents the organic solvent gas from coming in contact with the outside air, thus ensuring safe operations.

SOLUTIONS TO DIFFICULTY TO DRY OXIDIZABLE MATERIAL:

Taking advantage of the antioxidant property of inert gas, this technology allows the materials to e dried and transmitted in an antioxidant environment in the closed circulation system isolated from oxygen, which ensure quality of the drying process for readily axydizable material.

SOLUTION TO TOXIC GASES POLLUTION FROM RAW MATERIALS:

While some materials or solvents may produce toxic gases when vaporized, an mini spray dryer with closed cycle of inert gas would keep these toxic gases in the closed system and allow them to be collected in subsequent processes, thus reducing environmental pollution, which is favourable for environmental protection.

THE FOLLOWING SOLVENTS HAVE BEEN TESTED AND CAN BE USED WITHOUT RESERVATION:

	Methanol
	Ethanol
	Toluene
	Acetone
	Ethlylacetat
	Dichloromethane
	Hexane

Control & functionality

YC-501 mini spray dryer is designed to ensure that all
functions are simple to select and adjust, to quickly
achieve the optimum conditions for spray drying.
The operator can control the following functions:
Inlet Temperature, Gasflow Volume, pump speed,
de-blocker frequency.

Easy to use

PLC automatic control, one-click boot. Color
tuouch screen, fast setup and cleaning times
scale up to pilot or industrial scale possible.
Visible process due to glass assembly adjustable
particle size (1-25 microns).

Two fluid nozzle with SUS316L stainless steel

The stainless steel spray assembly consists of an inner tube for
the liquid sample leading to a small diameter jet. An outer tube
directs compressed air to the nozzle. All units are supplied with
0.7mm jets, other sizes are available as accessories. The spray
assembly incorporates an automatic de-blocking divice that
prevents the jet nozzle from becoming blocked, the de-blocking
needle is activated by an integral compressor. De-blocking is
sometimes necessary with materials which may solidify or when
large particles suspension cause blockages in the jet.
