Introduction

Background of Standard Revision and Technological Evolution

Compared with the 2001 version, the 2017 version of the standard has been mainly optimized:

Technical indicators	Requirements of the 2001 version	Adjustments of the 2017 version	Adjustment range
Cold trap evaporation temperature	-35℃~-55℃	-25℃~-45℃	Upper limit increased by 10℃
Heating plate temperature	0℃~150℃	30℃~120℃	Range narrowed by 30℃
Cold trap surface temperature difference	≤5℃	≤4℃	Required to increase by 20%

Definition of key terms

Vacuum freeze drying: The process of removing moisture from water-containing materials by sublimation in a vacuum environment after freezing at low temperatures

Total drying area: The total area of all drying trays (unit: m²)

Core performance parameter requirements

Parameter category	Indicator requirements	Test method
Evacuation time	≤12 minutes (to 133Pa)	6.3.1 Vacuum system test
Sublimation water volume per unit area	≥2.0kg/(m²·h)	6.6.2 Load test
Energy consumption of electric heating	≤2.5kW·h/kg	Calculated by formula (4)

Equipment selection guide

Heating method selection

Contact electric heating (J type): Suitable for small batch high value-added products
Steam heating (S type): Suitable for continuous production scenarios

Cold trap configuration plan

Built-in type: compact structure, suitable for places with limited space
External type (W type): easy to maintain, suitable for large equipment

Implementation suggestions

Key points for acceptance

Verify that the actual measured value of the drying chamber volume is ≥ 98% of the nominal value
Check that the surface temperature difference of the cold trap is ≤4℃ (Clause 6.6.2)
Insulation resistance test＞2MΩ (Clause 5.2.8)

Daily maintenance points

Regularly calibrate the vacuum gauge (Clause 6.2.d)
Use softened water in the heating system (Clause 5.2.6)
Storage for more than 18 months requires re-maintenance (Clause 8.3.3)
