  • Patent number: 4582263
    Abstract: A drum granulator is described in which at least a part of the cylindrical outer wall is resilient. This can be achieved, for example, by forming the drum from steel and fitting it with a resilient rubber lining, which is exposed in way of circumferentially extending slots in the steel. The drum rotates past pivotted rollers which are allowed to descend abruptly onto the resilient part of the wall, dislodging any material which adhered to it.

  • Patent number: 4567056
    Abstract: There is disclosed an edible fat suitable for producing margarines and low-fat spreads displaying good spreadability, melting behaviour and plasticity.Said fat is produced by interesterifying a mixture consisting of a liquid oil, a partially hydrogenated oil and a fully saturated fat, and fractionating to obtain a higher melting stearin and an olein which is substantially free from triglycerides from 3 saturated C.sub.16 -C.sub.18 fatty acids and has a level of triglycerides from 2 saturated fatty acids and 1 mono-cis or polyunsaturated fatty acid, which is higher than 15%. The interesterified mixture may contain some lauric fats.The olein can be used as such or can be mixed with palm oil and/or hydrogenated palm oil to produce spreads.
