VERFAHREN UND VORRICHTUNG ZUR TROCKNUNG VON GRANULATMATERIAL.
摘要
<p>A method for drying and/or freezing granular and similar matter in a particle form, particularly organic materials. The granular material is subjected to a drying agent or refrigerant from below in a mainly vertical jet which helps to keep the granular material in motion. There is a drying chamber (11) in a circulation loop (10) with an organ (13) for the through flow of the drying agent and/or refrigerant. In the loop there is a heat pump unit (12) comprising a main condenser (19) for heating the drying agent and an auxiliary condenser (21) for the removal of the surplus heat, there is also a distribution valve (23) to distribute the refrigerant from an evaporator (15) to the two condensers, in accordance with the need to supply heat to the drying agent and/or refrigerant.</p>
