I. Why do we need low-temperature spray dryer in laboratories?

Dififculties faced by traditional spray dryers when drying sugar-containing materials in labs, such as Chinese herbal medicines, natural product extractives and juice:

·Quick melting of such materials under high temperature;

·Melted sugar attached to the wall of drying chamber, hard to clean up;

·Having to add excipients such as starch and cyclodextrin;

·Not satisfying drying effect.

YC-1800 laboratory low-temperature spray dryer, a breakthrough of Shanghai Pilotech Instrument and Equipment Co., Ltd.: 

·Designed to reduce inlet air temperature to improve drying effects on sugar-containing materials;

·Absorbing the feedbacks from our users in the Chinese medicine field;

·Drying up Chinese herbal medicines, natural product extractives and juice at 105℃ to get high-yield powder with excellent fluidity and solubility;

·Easy and safe method of drying heat-sensitive materials such as biological products, sugar-rich natural Chinese medicine extractives, heat-labile polymers and materials that gasify when exposed to heat.

II. Technical features of YC-1800 laboratory low-temperature spray dryer

YC-1800 spray dryer is a perfect combination of low-temperature and high-temperature spray drying:

·Maximum inlet air temperature: 200℃;

·Meeting the experimental or technical demands of users for drying general materials;

·Inlet air temperature during the whole experiment: 105℃ (outlet air temperature: 60℃);

·Drastically reducing the temperature of materials;

·Overcoming the problems faced by heat-sensitive materials drying.

·Drying chamber made from SUS304 stainless steel and high borosilicate glass;

·Effective observation and adjustment of technical parameters during an experiment;

·Hard to break, thus saving experiment expenditure.

·Optional fluid-bed drying function;

·Effectively drying up powder to low water content;

·Much more effective than vacuum chambers or any other drying tools;

·One machine for two uses.

·Easy material preparation;

·Minimum material amount: 20-30ml, convenient for treatment of small samples;

·Maximum treatment capacity: 1,500ml/H, enabling quick treatment of vast materials.

Temperature protection:

·Automatic control of the draught fan operation;

·Continuous draught fan operating against manual misoperation;

·Automatic stop of draught fan at default temperature.

II. Technical features of YC-1800 laboratory low temperature spray dryer

YC-1800 laboratory low temperature spray dryer is a perfect combination of low-temperature and high-temperature spray drying. It has a maximum inlet air temperature of 200℃ and can meet the experimental or technical demands of users for drying general materials. The whole drying process can be finished under an inlet air temperature of 105℃ (outlet air temperature can be as low as 60℃). It drastically reduces the temperature of materials drying and solves the problems in drying heat-sensitive materials.

The drying chamber is made from SUS304 stainless steel and high borosilicate glass, which is helpful for effective observation and adjustment of technical parameters during an experiment. Meanwhile, the stainless steel body is hard to break, thus can help save experiment expenditure.

Fluid-bed drying is provided as an optional function. Besides liquids, many labs need drying lots of powders. But vacuum chambers or other drying tools are ineffective for drying powders. YC-1800 spray dryer, with built-in fluid-bed drying function, can effectively dry up powder that contains water to low water content. One machine can be used for two purposes.

Easy material preparation: The minimum amount of material needed is only 20-30ml, convenient for treatment of small samples. The maximum treatment capacity reaches 1,500ml/H and enables quick treatment of a large number of materials.

Temperature protection: The temperature of the heater will be very high at the end of an experiment, so it is necessary for the draught fan to continue to work to reduce the inner temperature. In this way, the safety of the device can be guaranteed. Consequently, automatic control of the fan operation is available in a YC-1800laboratory low temperature spray dryer. For safety, the draught fan cannot be turned off even in the case of misoperation. And the fan will not automatically stop until the temperature drops below the system default.
