摘要： A method for training an operator of a spray drying plant, the spray drying plant including a plurality of plant elements including pre-processing elements, a spray drying element, post-processing elements, powder recovery elements, and a programmable logic controller, PLC. The method including the steps of: obtaining a transient model of the spray drying plant, wherein the transient model includes transient sub-models of the plurality of plant elements; calculating repeatedly simulated sensor data based on the obtained transient model, using a processing unit; displaying on a display a training human machine interface, tHMI, configured to communicate with the transient model of the spray drying plant, and to display the simulated sensor data and control data for the transient model; and updating the transient model based on operator input on the tHMI, for controlling the transient model of the spray drying plant.

摘要： Disclosed herein is an external mixing pressurized two-fluid nozzle for atomising a liquid by means of liquid pressure and gas, comprising an inner feed liquid pipe (1) extending axially between an upstream end and a downstream end, having a feed liquid conduit (2), a feed liquid inlet (3) positioned at the upstream end and a feed orifice (4) positioned at the downstream end, and a co-axial first gas pipe (5) extending radially outside the inner feed liquid pipe (1) and forming a first gas conduit (6) between the first gas pipe (5) and the inner feed liquid pipe (1), the first gas pipe (5) having a gas outlet slit (7) positioned at the downstream end. Said external mixing two-fluid nozzle provides a swirling motion of the gas, which combined with a pressurized feed liquid enables the production of spray dried powder at industrially applicable capacities with low energy consumption and a small particle size.

摘要： A nozzle for cleaning-in-place of a vessel has a nozzle body to be connected to a wall of the vessel and defining an opening, a nozzle insert is contained within the nozzle body and is able to assume at least two distinct positions relative to the nozzle body, a first position in which the nozzle insert is retracted into the nozzle body and a second position in which the nozzle insert is advanced in the axial direction relative to the nozzle body and protrudes into the vessel. Apertures are exposed in the second position to allow distribution of a cleaning fluid. The nozzle insert has two nozzle insert parts, in mutual abutment in the first position and spaced from each other in a direction transverse to the axial direction in the second position to form a gap between adjacent nozzle insert parts, the apertures being exposed in the gap.

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 concerns a powder drying system (1) comprising a carbon monoxide (CO) gas detection system adapted for detection of CO gas from smoldering powders in a powder drying system component, such as a spray dryer chamber (200), a fluid bed (500) or a bag filter (400), which CO gas detection system comprises at least one inlet CO gas detector (3) arranged on at least one gas inlet of a powder drying system component such as to provide at least one inlet CO gas content measurement, at least one outlet CO gas detector (3) arranged on at least one gas outlet of a powder drying system component such as to provide at least one outlet CO gas content measurement, and an analyzing unit (5) adapted for receiving the at least one inlet CO gas content measurement, receiving the at least one outlet CO gas content measurement and comparing the sum of the at least one inlet CO gas content measurement and the sum of the at least one outlet CO gas content measurement while compensating for dilution, mixing, and time delay of the outlet CO gas content measurement. At least the at least one outlet CO gas detector (3) comprises an IR laser transmitter and is adapted for detecting over a measurement volume (6) and is arranged on the at least one gas outlet in such a way that said measurement volume (6) extends directly inside a gas flow (20) in said at least one gas outlet.
