Abstract: In the area of fruit juice treatment with respect to mineral content, only total demineralisation or addition of specific minerals has been practised until now. In certain illnesses, consumption of fruit juices has an adverse effect on the patient. Some patients suffering from kidney complaints and those on dialysis are allowed to consume only very low amounts of potassium. As the natural potassium content in fruit juices is high, these patients are not allowed to drink fruit juices. This has the effect, however, that they do not benefit from the other constituents of fruit juices that have positive physiological effects. Using the invention, it is now possible, by means of a calcium charged cation exchanger (polystyrene having sulpho groups crosslinked using 8% of divinylbenzene) to reduce selectively the content of potassium. A reduction to approximately 30% of the original content has been achieved up to now in apple juice.

Abstract: Glass is made from a feed consisting of batch materials and cullet in a furnace that is both electrically and gas fired. A batch-only hopper (1) discharges through a blanket conveyor (2) to a batch melting chamber (16) that is electrically fired and is connected via a submerged throat (6) to a fritting chamber (17) where the at least partly molten batch materials are mixed with cullet fed from cullet-only hoppers (10) by blanket feeders (9). The fritting chamber (17) is fired by a combination of electricity and roof-mounted flat flame burners (11). Material passes from the fritting chamber (17) to a secondary reheating and refining chamber (19) which is heated by regenerative gas burners (13). The separation of batch materials from cullet and separate melting thereof in a pre-melter (16) means that the feed to the secondary refining and conditioning chamber (19) is relatively free of fines and requirement to melt only cullet in the fritting chamber (17) and secondary refining chamber (19) enables those chambers to be operated at a lower temperature than the batch melting chamber (16). The resulting furnace makes efficient use of gaseous combustion and electrical energy and has low emissions of fines and oxides of nitrogen.
