摘要： The invention relates to a drying system (1) comprising a drying plant (2) and a heat pump assembly (3) comprising one or more heat pumps operating with a primary fluid and being connected to at least two heat sources and at least one heat sink by means of a number of heat exchangers in a fluid network, in which a secondary fluid circulates. The heat sources may comprise dew point dehumidification in at least one heat exchanger (41) of process gas entering the drying plant; and recovery in another heat exchanger (42) of latent and/or sensible heat from exhaust gas leaving the drying plant. The heat sink may comprise pre-heating in a heat exchanger (51) of process gas used within the plant. Further, a method of integrating a heat pump assembly into a drying system is devised. By the invention, it is possible to increase the capacity of the drying plant while reducing the specific energy demand.

摘要： The invention relates to a sampling apparatus for use in explosive environments comprising particles of a mean size of up to 500 μm, the sampling apparatus comprising a displaceable arm having a sample container, which displaceable arm has a first position where the sample container is inserted into a first zone for collecting a sample of particles into the sample container, and a second zone where the displaceable arm is outside the product stream, the second zone being contained in a housing with an opening for the displaceable arm. The sampling apparatus has an interface between the first and the second zone, which interface is selected from the list consisting of a closable member, a gate valve or an air knife. The invention also relates to a dryer comprising a drying chamber and a sampling apparatus of the invention. In a further aspect the invention relates to a method of estimating the flowability of a sample of organic particles.

摘要： The sanitary diverter valve (70) is for use in a drying system or powder conveying system including conveying lines and a purge line of a purge arrangement. The sanitary diverter valve comprises a valve housing (71) with a number of openings (72, 73, 74) configured to be connected to respective lines of the system. The valve housing (71) is substantially cylindrical and includes a first opening (72), a second opening (73) and a third opening (74). Furthermore, the diverter valve (70) comprises a rotatable diversion member (75) provided with a flow channel (76) having a first end (76a) and a second end (76b), an open space (77) being defined between the valve housing (71) and the rotatable diversion member (75). The rotatable diversion member (75) is configured to be rotated between a first position and a second position to allow that fluid communication is selectively provided between the first opening (72) and the third opening (74) and between the first opening (72) and the second opening (73) of the valve housing (71).

摘要： In the gas disperser (3), a flow conditioning device (5, 6) is located in the inlet duct section (32). The flow conditioning device comprises a hole plate (5) and a flow straightener (6) positioned in parallel with and at a distance (h) in the axial direction (axd) from the downstream side of the hole plate (5). The hole plate (5) has a predefined hole plate thickness (tp) in the axial direction (axd) and each flow straightener (6) has a predefined flow straightener length (Is) in the axial direction (axd), the flow straightener length (Is) being substantially larger than the hole plate thickness (tp).
