Abstract
A device for tempering and homogenizing viscous masses, particularly putty, and incorporating a combined heat exchanger and homogenizer (10), having a tubular part (12) through which the putty under pressure and tempering is caused to pass. In said tubular part (12) is provided a guiding device (16) designed compulsory to give the putty a plurality of direction changes relative to the tubular part (12). The guiding device (16) incorporates at least a first helical heat exchanger tube (17) arranged around a centrally disposed, second heat exchanger tube (18).
Claims9
A device for heating and homogenizing a viscous mass, comprising:
- a tube defining a flow passage for the viscous mass, the tube having an inlet for viscous material at one end of the flow passage and having an outlet spaced away from the inlet along the tube at the other end of the flow passage for outlet of the viscous material;
- a first helically coiled tube heat exchanger disposed inside the tube between the inlet and the outlet for guiding the viscous mass through the flow passage inside the tube and for mixing and homogenizing and for heating the viscous mass;
- a second tube heat exchanger disposed generally centrally in the tube between the inlet and the outlet, the first helically coiled tube heat exchanger being coiled around the second heat exchanger, the second heat exchanger also being for heating the viscous mass moving through the flow passage;
- a third helically coiled tube heat exchanger disposed inside the tube between the inlet and the outlet, the third heat exchanger also being helically coiled around the central second heat exchanger, and the helical coil of the third heat exchanger having the opposite pitch from the helical coil of the first heat exchanger.
A method for heating and homogenizing a viscous mass, comprising:
- feeding the viscous mass under pressure through a tube from an inlet in the tube to an outlet from the tube through a flow passage defined between the inlet and the outlet;
- heating the viscous mass while feeding the viscous mass through the tube from the inlet and outlet;
- the heating step comprising heating the viscous mass by first heating means extending straight through the center of the tube and by second heating means helically coiling around inside the tube, and directing the viscous mass through the flow passage along a pathway having many directional changes caused by the feeding of the viscous mass over the helical tube heat exchanger, for both homogenizing the viscous mass and for heating the entire viscous mass as it passes through the flow passage and comprising further heating the viscous mass by applying heat to the exterior of the tube in a heated casing around the tube.
