Apple Drying.

lots may be put up in 1-lb. and 2-lb. attractive cardboard cartons — these 

 may be sold as first quality. The particles may be put up similarly, and 

 sold as " Seconds." 



But the writer is of opinion that, 

 if the " Seconds," while dry and 

 hard, were ground into a meal, say 

 to the consistency of flaked oatmeal, 

 and put up in 1-lb. and 2-lb. 

 cartons, and sold as dried apple 

 " meal," they would then not lose 

 any of their commercial value. 



Mr. W. Dabb, orchardist, of 

 Croydon, has built an evaporator on 

 somewhat similar lines to this one; 

 and, while it was in course of con- 

 struction, Mr. Dabb was in consul- 

 tation with the writer. A few trial 

 lots have been put through, with 

 Plate 13. satisfactory results. 



Although this article deals specially with apple drying, it may be 

 incidentally mentioned that this evapoi'ator is capable of dealing with 

 any of the other fruits dried for commercial use.
