AB - COMPOSITE APPARATUS FOR DRYING CHEMICAL-PHARMACEUTICAL PREPARATIONS IN A SUSPENDED LAYER L. G. Golubev and K. S. Chukhlebov UDC 615.45:66.047.7 The suspended layer technique, in spite of its advantages, finds limited use for drying chemical- pharmaceutical preparations as yet. In drying by the suspended layer technique, only crystalline materials able to withstand the high temperatures of the drying agent [1] are successfully dried. This can be ex- plained by the fact that the majority of materials and, most of all, the preparations which contain salon (phenylsalicylate) possess a number of undesirable properties from the point of view of drying them: ad- hesiveness and liquefaction at 35-40 ~ . In order to make the subsequent tableting of the material possible when it is dry, it must be obtained as granules. At present, similar materials are usually dried in rack driers as an immobile layer while air -at room temperature is blown over them. This drying method is neither thorough nor economically effective. Attempts to dry low-melting preparations in driers of various design have not been successful since these apparatus were basically created for materials able to withstand considerably higher temperatures. Thus, the efficient drum drier [2] in the Kazan' Pharmaceutical-Chemical Plant
