This paper describes the theoretical and practical labor of an Experimental Factory of the Ministry of Agriculture in Aberdeen – Scotland with a pilot plant of a Accelerated Freeze Drying process (AFD). The book is divided in two parts: 1stdDescribes the engineering bases to scale equipments and give dimension of the system end operational parameters.
