Abstract
A process for producing a concentrate wherein a target component concentrate is obtained with low cost and in a simple manner from a solution containing a target component and unneeded suspended solid contents while unneeded suspended solid contents are removed. In particular, the process is one for obtaining a concentrate of first component from a solution containing a first component, which comprises a step of rapidly freezing the above solution to thereby obtain a frozen matter, a step of thawing all the frozen matter relatively slowly, and a first recovery step of recovering an initially thawed fraction obtained in the initial stage of thawing to thereby obtain a concentrate of first component.

A process for producing a concentrate in which the concentrate of a first component is obtained from a solution containing the first component, comprising:
- a freezing step of quickly freezing the solution to obtain a frozen matter;
- a thawing step of thawing the whole of the frozen matter at a thawing speed Vmelt (g/min) that satisfies the following formula 1 (wherein A means a surface area (cm2) of the frozen matter);
- and
- a first recovering step of recovering an initially thawed fraction obtained at an initial thawing stage, thereby to obtain the concentrate of the first component:
- (A/170)>Vmelt Formula 1.
A process for producing a concentrate in which the concentrate of a first component is obtained from a solution containing the first component, comprising:
- a freezing step of quickly freezing the solution to obtain a frozen matter;
- a thawing step of thawing the whole of the frozen matter during a time T (min) that satisfies the following formula 2 (wherein A means a surface area (cm2) of the frozen matter and W means a weight (g) of the frozen matter);
- and
- a first recovering step of recovering an initially thawed fraction obtained at an initial thawing stage, thereby to obtain the concentrate of the first component:

- and
- a first recovering step of recovering an initially thawed fraction obtained at an initial thawing stage, thereby to obtain the concentrate of the first component.
