Abstract
Abstract A method of defoaming sugar juice in a countercurrent cossette mixers wherein the foam is removed from a mixer section of the cossette mixer to a let down device serving for the destruction of the foam and the juice which is freed from foam is sent back into the mixer section. The foam removal is performed by means of a juice-part-stream, the juice quantity of which is less than the raw-juice output. The foam feeding juice is distributed uniformly over the entire cross-section of the let down device and the juice part stream serving the foam removal is heated up about 5* to 10* C, so that simultaneously a partial sterilization of the sugar juice takes place in the mixer.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
37 words
The method, as set forth in claim 1, wherein said step of increasing the temperature is performed at least partly by feeding of a finely divided vapor into said let-down device, causing an additional mechanical foam destruction.
Claim 2
Dependent Claim
29 words
The method, as set forth in claim 1, which includes the step of adding of predetermined quantities of foam damping means to said juice-part-stream to support the foam destruction.
Claim 3
Dependent Claim
26 words
The method, as set forth in claim 1, wherein said juice part of said stream flows from below in an upward direction through said cossette mixer.
Claim 4
Dependent Claim
25 words
The method, as set forth in claim 1, wherein said stream is fed into said let-down device below the liquid level in said let-down device.
Claim 5
Dependent Claim
28 words
The method, as set forth in claim 1, wherein said juice in said let-down device is ventilated to the air and said juice therein is at higher pressure.
Claim 6
Dependent Claim
27 words
The method, as set forth in claim 1, further comprising the step of providing a lower-pressure in said let-down device compared to that in said cossette mixer.
