Four basic conditions during freezing drying process:
1. Surface temperature of cold trap lower than -35℃
2. Product is below freezing point.
3. Vacuum degre ⩽40Pa
4. Production temperature is controlled between -40℃~+60℃ with sublimation potention heat, and products not melt above eutectic point.
a. Pre-freezing; b. Initial drying; c. Main drying; d. reduce drying; e. ultimate drying.
a. Product water rate in best economical principle is between 60~90%, tray loading thickness at 10~15mm.
b. Pre-freezing can be in machine or cold room;
c. Heating plate must control product temperature at 5~10℃ below eutectic point during main drying period and no melting, maximize temperature difference with cold trap to speed up drying rate.
d. Heating plate temperature in ultimate drying stage would be product highest temperature without spoilage.
