YC-501 Inert Loop Spray Dryer

  • The smallest inert loop spray dryer in the market.
  • The processing capacity is 500ML/H, the minimum material volume is 20ML.
  • Modular design, no need to connect the nitrogen circulation system (inert loop) when drying aqueous solutions.
  • Optional vacuum system, it can be upgraded to vacuum low temperature spray dryer.

Pilotech Inert Loop Spray Dryer

YC-501 inert loop spray dryer adopts modular design. The spray dryer main machine can be used for spray drying of the aqueous solution, which can save the use of nitrogen.

After connecting with nitrogen circulation system, it can be used for spray drying of organic solvents. The equipment is small, which covers an area of less than 1 square meter. Easy to operate, safe and reliable.

Inert Loop Spray Dryer: The Complete Buying Guide

Laboratory needs dry samples: one is aqueous solution and the other is organic solvent. Most laboratory spray dryers can only be used for spray drying aqueous solution. However, if your materials are flammable and explosive organic solvents, YC-501 inert loop spray dryer could be your best choice.

YC-501 Inert loop spray dryer are specially used for spray drying organic solvents. They are safe and reliable and can also be used to spray dry aqueous solutions.

Pilotech YC-501 inert loop spray dryer replaces compressed air with nitrogen or other inert gases instead as hot air. Their working process is as follows: a sample is transported to the spray head through a peristaltic pump and atomized into small liquid droplets under the action of compressed nitrogen. During atomization, the small liquid droplets meet heated nitrogen and are rapidly dried. The dried materials (powder) pass through a cyclone separator and are collected into a collection bottle. After entering the nitrogen circulation system, the waste gas is first filtered precisely to recycle some powder inside and then condensed to recycle organic solvent vapor, the recycled nitrogen enters the next cycle.

Safety is an important index for inert loop spray dryer. We have set that if the oxygen concentration in the system goes beyond 2.5%, the equipment will automatically stop or be unable to start so as to ensure the safe use of YC-501 spray dryer.

YC-501 inert loop spray dryer is applicable to spray drying various organic solvents including methanol, ethanol, acetone, diethyl ether and toluene.

They are also well applied to various industries such as pharmaceuticals, food, chemicals, polymer materials, ceramics, and energy.

And YC-501 inert loop spray dryer has three specifications, 500ml/h, 1500ml/h and 3000ml/h. The 500ml/h model is suitable for spray drying micro samples, while the 3000ml/h model are suitable for pilot scale experiment.

You don’t have to worry about the use of the equipment because we have made a video about the operation procedures. That video will teach you how to use YC-501 spray dryer system, in a step by step process.
