    • Method of drying a medium for producing a porous matrix from a solution, a paste, an extract, a granulated material or such, where a liquid inert agent is fed into a vessel (5) at controlled pressure and amount through a valve (7), transferring the pressurized liquid inert agent to a mixing vessel (4), said mixing vessel (4) also receiving the solution, such as paste, extract or granulated material, through an inlet valve (10), adjusting the pressure and temperature inside the mixing vessel (4) to desired levels by a release valve (6), upon complete mixing of the inert agent with the solution, the mixture is expanded into a porous matrix and injected into a drying circuit through a drying chamber (3), the matrix thereby being kept suspended in the drying chamber by the flowing drying medium, supplied by the blower (2), the matrix moisture being removed from the mixture through a heat exchanger coil comprising a first heat exchanger (11) where the water vapour is condensed and removed from the circuit and finally the drying medium is adjusted to the desired inlet condition in a heat exchanger (1) before the drying medium flows through the matrix and the process is repeated.
    • 从溶液,糊剂,提取物,造粒材料等中干燥用于制备多孔基质的介质的方法,其中液体惰性剂以受控的压力和量通过阀(7)进料到容器(5)中, 将加压液体惰性剂转移到混合容器(4)中,所述混合容器(4)还通过入口阀(10)接收诸如糊剂,提取物或造粒材料的溶液,调节其中的压力和温度 在将惰性剂与溶液完全混合后,将混合容器(4)转化成期望的水平,将混合物膨胀成多孔基体并通过干燥室(3)注入干燥回路中, 通过由鼓风机(2)提供的流动的干燥介质将基质保持悬浮在干燥室中,基质水分通过包括第一热交换器(11)的热交换器盘管从混合物中除去,其中水蒸汽冷凝 并删除f 在干燥介质流过基质之前,最后将干燥介质调节到热交换器(1)中所需的入口条件,并重复该过程。
