Abstract:
The invention relates to a spray drying system (1 ) comprising a spray dryer with a drying chamber (2) and a process air/gas supply device, at least one powder recovery unit (4), a conveying line (11 ) for powdery material such as fines from the powder recovery unit, a connection assembly (10) connecting the powder recovery unit or the conveying line to a cleaning-in-place, CIP, arrangement including a CIP line configured to transport CIP liquid. The connection assembly (10) comprises a sanitary valve (20) including a first inlet (12) to the conveying line or the powder recovery unit, and a valve member (21 ) moveable between an open position and a closed position, wherein in the closed position, one part of the valve member (21 ) seals the conveying line (1 1 ) and when in the open position, the valve member (21 ) is moved to provide communication between the CIP line (15) and the conveying line (11 ) or the powder recovery unit (4), thereby allowing CIP liquid to enter and exit the sanitary valve (20) through the CIP line (15) and into the conveying line (1 1 ) or the powder recovery unit (4) via said first inlet (12). In another aspect of the invention, a method for cleaning a spray drying system is described.
Abstract:
Disclosed herein is a process for production of an instant coffee product in a high yield, comprising the steps of extracting roast and ground coffee beans with water having a temperature of 80° C. or less, to produce a first extract and spent coffee grounds, adding water to the spent coffee grounds to produce an aqueous suspension, hydrolysing the aqueous suspension using a hydrolysing enzyme to produce a second extract and spent remains, adding the first extract to the second extract, optionally after concentration and/or drying of the second extract, to obtain a combined extract, and drying the combined extract to obtain an instant coffee product. The high yield is obtained due to the reduction of enzyme inhibiting substances.
Abstract:
In the air disperser (4) having a number of components including a top, a bottom and an outer circumferential wall forming a space (45) defined within an inner radius and an outer radius and having an air inlet (81), a set of guide vanes (7), and an air outlet (82) at the inner radius adapted to be positioned above a feed outlet from atomizing means, at least some of the components are formed by precision metal forming such as metal spinning.
Abstract:
In a spray drying apparatus, comprising in a usual manner a drying chamber, an air disperser, and at least one pressure nozzle arrangement (4), means are provided for emptying the feed in the nozzle arrangement(s) (4) after the supply of feed from a feed system (5) is halted and before the nozzle arrangement(s) (4) are removed from the drying chamber and positioned in a cleaning system (7). The emptying takes place while maintaining atomization in the nozzle arrangement (4). The feed emptying system (6) comprises a pump (60), a pressurized air/gas source (61) and a conduit (62), and the spray drying apparatus at least one valve (45, 53, 63, 64, 65, 66) allowing switching from the feed system (5) to the feed emptying system (6).
Abstract:
The closure element (201) is adapted to be installed in a vessel wall provided with an aperture and has a peripheral flange (202, 222) and a central cover unit (203). The closure element (201) is provided with at least one light source (241) within a predefined zone (235) located in the central cover unit (203) and the light source is confined within the central cover unit.
