乾燥粒子は、下側容器端部においてガス流から分離され
、かつ収容容器に入り、ここから取出される。A suspension or solution to be treated, for example a pigment suspension, is obtained from the microparticles in a spray dryer. In a drying container, the residue T)'+tr, which is dispersed in a hot gas stream in most cases in a unidirectional flow motion, absorbs the moisture of the suspension and leaves behind dried bioacid particles. These dry particles are separated from the gas stream at the lower vessel end and enter the receiving vessel from which they are removed.

全に分難することが望ましい。For the separation of the product/gas stream, a ring space is usually inserted between the drying vessel and the receiving vessel, through which the waste is removed by means of pressure or underpressure. Since the product particles still remaining in the gas stream are then mostly crushed to dust in the subsequent separation device, it is desirable to separate them as completely as possible.

As described in , a guide plate is provided in the region of the ring space at the end of the drying container, which constricts the flow cross section;
The gas flow is thereby increased in flow velocity and subsequently deflected strongly towards the ring space.
粗い生成物についてはこれら構造処置で十分であるが、
それに反してミクロ粒子において固体の収量は満足すべ
きものではない。These structural treatments are sufficient for coarse products, but
On the other hand, the solids yield in microparticles is not satisfactory.

面の拡大を行う。According to the invention, this problem is solved by means of a separation device of the type mentioned at the outset, as follows. That is, the guide device consists of two flow guide elements in direct succession, of which the first one in the direction of flow causes a contraction of the flow cross section at the end of the drying container;
and the second one carries out an enlargement of the flow cross section at the level of the ring space.

成る（第１図）。In the area of the annular space 3 between the drying container 1 and the receiving container, here the receiving cone 2, a guide device for the product/gas flow is provided, which guide device is arranged at the end of the drying container. It consists of a first flow guide member that constricts the flow cross section and a second flow guide member that immediately follows this and widens the flow break IT4j at the level of the ring space (FIG. 1).

Become. In this case, the retracted guide plate 5 has the same slope as the receiving cone 2 and the lower edge of this guide plate ends at the level at which the enlarged guide plate 6 begins, with this enlarged guide plate on the other hand. It has been found that very high solids yields are obtained when reaching the beginning of the I1 g cone. The geometry of the equipment part (
