The material leaving the dryer is heterogeneous, dif- fering in size, color, cleanliness, and moisture con- tent (e.g., besides the appropriate cube sizes there are smaller pieces, too).
Finishing procedures can be placed into two groups:
r Procedures ensuring the main requirements: a. Classification by size
b. Classification by color, cleanliness, moisture content
c. Air separating/classifying
r Improving processes which increase the variety and value of the products:
a. Mashing, cutting, granulation
b. Fine classification into some given fractions c. Powder grinding, sieving
d. Mixing, producing mixtures
Packing
Dried products cooled to room temperature are packed as required by consumers. Requirements for packing materials are the following: protect the prod- uct against moisture, oxygen, light, alien odors, bruis- ing, impurities, and insects. The finer the size of the product and the higher the surface area, the more it is influenced by damaging effects. Packaging is suit- able if the material, closure, dimensions, strength, labeling, and aesthetic appearance meet marketing specifications, if it is non-toxic and ensures the safety and quality of the product for a preset time. Storage
At storage the following must be ensured: r Safety of the wrapping
r Legibility of the label
r Appropriate storage temperature (conditioned, cooled air space)
r Appropriate turning at the store r Exclusion of risk for contamination r Eligibility of the specification of food law r Appropriate clean environment
r Extermination of rodents and insects.
