working Principle

COMPARATION

Dry method	Freeze Dryer	Dry Wind Spray Dryer
Drying mechanism	Vacuum sublimation	Dew point difference
Drying environment	Vacuum	Normal pressure
Drying temperature	< -20ºC	35ºC-60ºC
Vacuum sublimation state	Solution state	Solution atomization state
Evaporation surface area	Small	Large
Drying efficiency	Poor, generally >24 hours	High, generally about 3 seconds
Powder state	Block	Powdered
Accumulation thickness	Required, generally cannot exceed 10mm, the thicker the thickness, the longer the drying time, the worse the drying efficiency	None
Conjunctival phenomenon	When the solution is sublimated, the surface of the solution is prone to conjunctivaeion, which hinders the sublimation of water	No conjunctival phenomenon
Influence on materials	Long drying time has a certain impact on biological stability	Short drying time, relatively small impact on biological stability

Safety parameters

• When the equipment is running, the noise level at the distance from the equipment operator (less than 1 meter) is below 75dB
• There are obvious warning signs at dangerous parts
• Comply with the requirements of equipment safety design specifications

Dried sample


Basic parameters

• Feed rate: 50~2000ml/h
• Metal parts in direct contact with drugs must be made of 316L stainless steel, and other parts that do not contact materials, such as brackets, can be made of 304 stainless steel.
• The outside of the equipment can withstand 75% ethanol, 0.2% chlorhexidine and other disinfectants for wiping and disinfection, and can also withstand air disinfectants including 84, formaldehyde, ozone, hydrogen peroxide and acetic acid.
• The outside of the equipment can withstand 75% ethanol, 0.2% chlorhexidine and other disinfectants for wiping and disinfection, and can also withstand air disinfectants including 84, formaldehyde, ozone, hydrogen peroxide and acetic acid.
• Relevant data or operation records that need to be monitored and displayed online during the process, such as time, pressure (mechanical display), temperature, flow, alarm information, operation and program running process, can be printed out. 
• The monitoring interface should include the equipment operation status (such as: preparation, operation, shutdown, etc.), the system program operation process, the data during the equipment operation (such as: temperature, pressure, air volume, etc.), the connection of the corresponding pipelines and valves, the feed pump, and the status of the atomizer opening and closing (which can be displayed on the dashboard). 
• It is necessary to equip the feeding system, including Lange peristaltic pump and Lange feed pipe.
• It is necessary to equip the atomization drying system, including atomizer, air compressor, pressure regulating valve, drying tower, perspective mirror, etc.
• It is equipped with an inlet temperature sensor with a detection range of 0-250ºC
• It is equipped with an exhaust temperature sensor with a detection range of 0-150ºC
• It is necessary to equip the product recovery system, including cyclone separation, collection barrel or cup (316 stainless steel or glass), collection valve, etc.
• The electric control system is of Xinjie brand, and the electric control auxiliary system is of Schneider brand
• With cyclone collector
• Exhaust dust collector: high temperature resistant bag filter or other suitable dust collector.
• Supporting equipment (if any): dew point meter (Michel brand)
• The equipment needs to adopt appropriate design to prevent static electricity and prevent product dust from escaping from the equipment system to the operating space and surrounding environment.
• Discharge collection valve: The interface is a clamp-type quick connection
• Auxiliary equipment should be brought by itself, such as air compressor, dew point meter, cold water circulation unit, etc. The installation site only provides civil water and electricity public engineering facilities, and the system should be guaranteed to operate normally after installation.
