This paper shows the convective drying of the parsley and the celery (their roots and leaves). The root of the parsley and the celery are separately dried, and their leaves are separately dried, too. The temperature of the incoming air was 60ºC - 80ºC at both parts of the plants. The period of drying the root lasted 165 minutes, while the drying of the leaves took 75 minutes. Final results are compared in order to make the conclusion which parts of the plants are faster dried, and what are the reasons for that.

The results of the chemical investigations of variously treated acorn samples are presented in this paper with the aim of obtaining data on the amount of nutritious components and biologically active substances. The Quercus robur acorn, which belongs to the Fagaceae family, was investigated in a raw, thermally treated form and as an extract that was subsequently dried in a dryer with a fluidized bed.
