摘要： The invention refers to a method of brazing together thin heat exchanging plates of an iron based base material provided with port holes and a pressing pattern of elevations and depressions over the heat exchanging area of the plates and, if present, also over the distribution area to a plate heat exchanger. The plates are coated with brazing material and are arranged such that contact between elevations and depressions in adjacent plates is obtained prior to the brazing together. The plates are then brazed together at the resultant contact points. Only 5 - 40%, preferably 10 - 30 %, of the heat exchanging area and the distribution area are coated with brazing material prior to the brazing.The invention also comprises a brazed plate heat exchanger built of thin heat exchanging plates of an iron based base material provided with port holes and a pressing pattern of elevations and depressions over the heat exchanging area and, if present, also over the distribution area which has been produced according to the method of the invention. In the brazed heat exchanger the brazing material used for the brazing is present mainly in the brazing joint.

摘要： Fat product which is spreadable at refrigerator temperature and contains 35-55% fat, 4-7% protein and 41-58% water. The protein has been obtained from an ultra-filtrated milk product, at which the fat product after mixing the protein concentrate with the fat raw material and homogenization of the fat spheres consists of a stable oil-in-water emulsion. The emulsion is stabilized by the milk protein. The fat product is free from additives in the form of stabilizing agents and emulsifiers. The method to manufacture the fat product is seen from the attached flow-chart, which shows the steps in the process.

摘要： In a plate heat exchanger the heat transfer plates (7, 8) are in pairs welded together to form cassettes (6). The two plates in every cassette bear on each other via corrugation ridges (25), which are crossing each other and create a flow path (33) between them for a first fluid. The cassettes (6) bear on each other via elevations (26), which are higher than the corrugation ridges (22) on the outsides of the cassettes. Between the cassettes (6) flow paths (34) are delimited for a second fluid. The main directions of flow for the two fluids are in parallel. Each one of the mentioned elevations (26) is elongated and extends with its longitudinal axis substantially in parallel with the main directions of flow for the fluids, bridging at most two valleys (23) between corrugation ridges (22) extending next to each other.
