YC-018A Pilot Scale Inert loop spray dryer

Efficient and safe Spray Drying of aqueous and organic solutions

The Pilot scale Inert loop spray dryer YC-018A (3500ml/h) ,is the result of 15 years continuous development , 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.

YC-018A Pilot Scale Inert loop spray dryer PRINCIPLE

To safely spray dry inflammable solvents, a new operating principle which uses a combination of the Spray Dryer YC-018 pilot scale spray dryer and the Inert Loop , 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-018A pilot scale  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 preset by the user as needed).

Closed nitrogen cycle.

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.

For organic solvents

While organic solvents are generally flammable and explosive, an explosion-proof, Inert loop 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.

Solution to difficulty to dry oxydizable material

Taking advantage of the antioxidant property of inert gas, this technology allows the materials to be dried and transmitted in an antioxidant environment in the closed circulation system isolated from oxygen, which ensures quality of the drying process for readily oxydizable 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 favorable for environmental protection.

The following solvents have been tested and can be used without reservation:

Methanol

Ethanol

Toluene

Hexane

Acetone

Ethylacetate

Dichloromethane*

* additional DLSB recommended

YC-018A Pilot Scale Inert loop spray dryer Controls & Functionality

YC-018A pilot dcale  Inert loop spray dryer ensure that all functions are simple to select and adjust, to quickly achieve the optimum conditions for spray drying. And the operator can control the following functions:

Inlet Temperature

Gasflow Volume

Pump Speed

De-blocker Frequency

YC-018A Pilot Scale Inert loop spray dryer Easy to use

PLC automatic control,One-click boot.

Color Touch Screen,Fast setup and cleaning times

Scale up to pilot or industrial scale possible.

Visible process due to glass assembly

Adjustable particle size (1 – 100 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 with 0.7mm jets, other sizes are available as accessories.

Automatic de-blocking device

The spray assembly incorporates an automatic de-blocking device, that prevents the jet nozzle from becoming blocked, the de-blocking needle is activated by an integral compressor. So de-blocking is sometimes necessary with materials which may solidify ,or when large particles in suspension cause blockages in the jet.

Trusted by the users

Over 1,500 customers of top universities, enterprises and research institutes use our mini spray dryer. And exported to more than 40 countries & regions such as the United States, Italy, South Korea, Mexico,Singapore, Canada, Malaysia, Chile and Russia.
