Abstract:
The present invention relates to a process for preparing modified green coffee beans for roasting, comprising the steps of a) providing a liquid coffee berry pulp or a liquid extract thereof and green beans from coffee berries, b) contacting the green beans with the liquid coffee berry pulp or the liquid extract thereof, and c) drying the modified green beans. When roasted, the modified coffee beans exhibit improved tasting notes and a decreased amount of undesirable compounds.
Abstract:
The invention relates to a process for preparation of spray dried particles, comprising the steps of spraying in a chamber a liquid feed comprising one or more solvents, and supplying a drying gas to the chamber with one or more solvent vapours having a dew point selected to provide a desired property to the spray dried particles.
Abstract:
Disclosed herein is a method for reducing the amount of coarser particles from a stream of flue gas prior to treatment by a spray dryer absorption process (SDA). The method comprises the steps of directing a stream of flue gas containing entrained particles of varying sizes through a curve, thereby subjecting the particles to a centrifugal effect, collecting the particles predominately of the coarser size at a particles collecting means provided in the outer circumference of the curve, dispersing the flue gas reduced in particles of coarse particle sizes into the chamber of a spray dryer absorption apparatus, wherein the particles content of the original flue gas stream is above 20 g/Nm 3 . Also an apparatus for performing the method and a gas disperser is disclosed. The method substantially reduces the cost of the entire plant for treating flue gas having a high content of entrained coarse particles by eliminating the need for a particle pre-collector upstream the SDA.

Abstract:
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).
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:
The insert (20) is adapted to be fitted into an atomizer wheel. Each insert (20) has a longitudinal axis and comprises an inner end face (21), an outer end face (22), an external surface (23) and an internal surface (24) defining a channel (35) having a centre axis (c) and extending between an inlet (25) at the inner end face (21) and an outlet (26) at the outer end face (22). At least the inlet (25) is offset from the longitudinal axis such that the centre axis of the channel (35) is offset from the longitudinal axis of the insert (20). The insert (20) is adapted to be utilized in an atomizer wheel for a spray dryer for atomizing slurries of abrasive material, for instance for spray drying ab- sorption for flue gas cleaning.
Abstract:
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.
