Abstract: A citrus juice concentrate processor homogenizes a mixture of citrus juice and pulp within or after a multi-effect, multi-stage evaporator. The homogenizer employs a positive displacement pump for pumping the citrus juice mixture through an orifice with a high pressure differential across the orifice. The homogenizer reduces viscosity of the citrus juice mixture. Inter-stage placement of the homogenizer further enables final citrus juice concentrate Brix levels of 65.degree.Brix and greater to be achieved.
Abstract: Deodorizing and/or physical refining of relatively small, varying charges of high-boiling liquids, viz. fatty acids, edible oils, fats, glycerides and other high-boilding esters, is conducted continuously in a single-stage or multi-stage falling-film column (20) through the trickle passages (23) of which stripping steam is passed in counter-current flow. In the supply conduit (15, 15', 15", 15'") leading to the falling-film column and in the discharge conduit (30, 30', 30", 30'") leading away from the bottom (26) of the falling-film column a plug-flow of the liquid is maintained. Upon a change of charge the fresh liquid to be treated is normally introduced into the supply conduit--without any blank charge--directly following the liquid of the preceding charge. Charging of the liquid onto the deflector (22) in the head (21) of the falling-film column is interrupted for a short period of time when the front of the liquid of the fresh charge has reached a check valve (16) disposed adjacent said deflector.
Abstract: The continuous process makes it possible to reduce the water content of polymers to minor residual levels (ppm) by adding to a W/O-emulsion an extractant which is subsequently evaporated with the oil.
