Abstract:
Vacuum freezing drying(FD),hot air drying(AD)and a combined drying,using hot air drying in the initial phase and vacuum freezing drying in the final phase(AFD)for wet books after aquatic deacidification are compared in terms of drying time,drying energy,brightness,color,tensile strength,tearing strength,folding strength and sensory evaluation in the paper. The results showed that FD is the best choice in terms of the tensile strength,color and shape of books while FD costs the longest drying time and the largest drying energy. The drying quality of AD is the worst among the three methods while it costs the shortest drying time. The drying quality of AFD is between AD and FD. Considering the drying time and drying quality,AFD is worth further studying for wet books.
