Abstract: The object of the invention is a floating split butterfly valve that allows connection of two processing devices or containers in a way that one of the devices (e. g. a transport device or a container) is closed by one half of the valve (passive part) while the other device (e. g. a stable device or a container) is closed by another half of the valve (active part), wherein the material (powder and/or liquid substance) transferred from one device/container into another device/container cannot get trapped in dead corners of the valve and does not get accumulated in the equipment.

Abstract: The object of the invention is a horizontal paddle dryer that is used for normal or vacuum drying of soaked substances that are in the form of dry powder mixtures or granulates in a manufacturing process and are soaked and mixed (normally with solvents) due to technological needs. Once drying is completed, the interior of the dryer needs to be washed due to various types of substances that differ from each other in content and properties. The construction of the horizontal paddle dryer of the invention allows simple and effective washing of the horizontal paddle dryer without an additional removal of washing heads during the washing of the dryer.

Abstract: A self-cleaning retract washing head with a pneumatic drive designed for efficient washing of vessels or containers and intermediate components for the preparation of solutions in pharmaceutical and food industry, said solutions being at an over-pressure of up to 6 bar, wherein the constructional solution to the washing head of the invention provides for a simple and efficient self-cleaning of the washing head. The self-cleaning retract washing head (1) with the pneumatic drive is provided with a movable bar (2) with a washing ring (5), wherein at the end of the bar (2) on the washing ring (5) an annular element (3) with grooves (3?) is pivotably arranged, which grooves cause rotation of the annular element (3).

Abstract: A process device for coating particles in which, on the inside wall (1), there are one or more units installed. Each unit includes a swirl flow generator (4) around which a straight or curved perforated plate (3) and draft tube (5) are located in cross-section. A single or multi-phase spraying nozzle (6) is installed centrally through the swirl flow generator (4) with a conduit (7) for dispersion for coating and a conduit (8) of compressed air. The swirl flow generator (4) has at an angle from the vertical adjacent grooves (18) that open outwards, with the angle of grooves (18) to the vertical line are between 10 and 45°.

Abstract: The subject of the invention is a process device for coating particles that falls within the field of chemical and pharmaceutical technology. It represents an improvement on the process equipment for coating particles by spraying from the bottom and works on the principle of fluidization technology. The process device for coating particles, according to the invention which has within the wall (1), one or more units placed, for which each unit consists of a swirl flow generator (4) with a perforated plate (3) and a draft tube (5) where centrally through the swirl flow generator (4) a single or multi-phase spraying nozzle (6) with a coating dispersion inflow (7) and inflow (8) of compressed air is installed, in which the swirl flow generator (4) has outward open and at an angle with regard to the vertical installed grooves (18).
