Abstract. The desiccation of plants requires large energy
consumption. In the proposed drying method traditional heating
can be replaced by solar heating. We present the experimental
research performed to achieve the drying process in cereal seeds
drying equipment with dual heating source.
Keywords: drying process, seeds drying, solar heating.
ELECTROPHYSICAL METHODS FOR RECYCLING OF THE
SECONDARY MILK PRODUCTS

Abstract. Electrophysical methods are some of the most effective
for processing protein-carbohydrate milk raw materials. In this paper the
electroactivation of initial whey was used with a subsequent recovery of
a protein-mineral concentrate as well as of deproteined whey for lactose
processing. The proposed method of electrofractionation of secondary
milk raw materials is found to be a reagentless, low-temperature process
and it can be included in a wasteless recycling of whey aimed at the
production of protein-mineral concentrate and lactose and lactulose
products.
Key words: secondary milk products, protein-mineral concentrate,
lactose and lactulose products.
ASPECTS REGARDING THE DESIGN OF A ROTARY DRYER
FOR AN EQUIPMENT WHICH COMPRESSES SAWDUST
by
PETRE RĂDUCANU
Abstract. The wood wastes, resulting from the forest exploitation
and from the wood processing, have to be very carefully treated, in
order not to produce a huge pollution. These wood-refuses have to be
turned, through drying and compression, into burning woodbricks,
which can be used for energetical purposes. For this reason was design
a mobile equipment, in which, a dryer used for the diminishing of the
sawdust humidity, was integrated. The paper presents the way in
