at least one volume-reducing element ( 40 ) which is configured to be releasably attached to the distributor bottom ( 20 ), on a side ( 20 - 1 ) of the distributor bottom ( 20 ) oriented toward the product container opening ( 14 ), and by which a free volume of the product container ( 10 ) between the distributor bottom ( 20 ) and the product container opening ( 14 ) is reduced,
wherein the volume-reducing element ( 40 ) has a bottom region ( 42 ) and a casing ( 41 ),
wherein the bottom region ( 42 ) of the volume-reducing element ( 40 ) is configured to be releasably attached to the distributor bottom ( 20 ), and
wherein the volume-reducing element ( 40 ) has a circumferential seal ( 43 ) in a transition between the casing ( 41 ) and the bottom region ( 42 ), with which seal the volume-reducing element ( 40 ) is configured to be arranged on the distributor bottom ( 20 ).

2. The product container ( 10 ) according to claim 1 , wherein the volume-reducing element is conical.

3. A product container for a fluidized bed installation ( 1 ), the product container comprising:
a product container wall ( 12 ),
a product container bottom ( 13 ),
a product container opening ( 14 ) opposite the product container bottom ( 13 ),
a distributor bottom ( 20 ) between the product container bottom ( 13 ) and the product container opening ( 14 ), and
at least one volume-reducing element ( 40 ) which is configured to be releasably attached to the distributor bottom ( 20 ), on a side ( 20 - 1 ) of the distributor bottom ( 20 ) oriented toward the product container opening ( 14 ), and by which a free volume of the product container ( 10 ) between the distributor bottom ( 20 ) and the product container opening ( 14 ) is reduced, wherein the distributor bottom ( 20 ) has an incident-flow element ( 30 ), which is mounted to the distributor bottom ( 20 ) on a side ( 20 - 1 ) of the distributor bottom ( 20 ) oriented toward the container opening ( 14 ).

4. The product container ( 10 ) according to claim 3 ,
wherein the volume-reducing element ( 40 ) encloses the incident-flow element ( 30 ) in a mounted state on the distributor bottom ( 20 ) and/or
wherein the incident-flow element ( 30 ) has the same geometric shape as the volume-reducing element ( 40 ).

5. A product container for a fluidized bed installation ( 1 ), the product container comprising:
a product container wall ( 12 ),
a product container bottom ( 13 ),
a product container opening ( 14 ) opposite the product container bottom ( 13 ),
a distributor bottom ( 20 ) between the product container bottom ( 13 ) and the product container opening ( 14 ), and
at least one volume-reducing element ( 40 ) which is configured to be releasably attached to the distributor bottom ( 20 ), on a side ( 20 - 1 ) of the distributor bottom ( 20 ) oriented toward the product container opening ( 14 ), and by which a free volume of the product container ( 10 ) between the distributor bottom ( 20 ) and the product container opening ( 14 ) is reduced, wherein a lifting device ( 50 ) is constructed on a side ( 20 - 1 ) of the distributor bottom ( 20 ) oriented toward the product container opening ( 14 ), said lifting device being equipped to move the at least one volume-reducing element ( 40 ) between at least a first position (A) and a second position (B), and
wherein the volume-reducing element ( 40 ) rests with a bottom ( 42 ) thereof against the distributor bottom ( 20 ) in the first position (A) and with the bottom ( 42 ) thereof spaced apart from the distributor bottom ( 20 ) in the second position (B).

6. The product container ( 10 ) according to claim 1 , comprising a plurality of volume-reducing elements ( 40 - 1 , 40 - 2 ) having different sizes.

7. The product container ( 10 ) according to claim 6 , wherein two of the plurality of volume-reducing elements ( 40 - 1 , 40 - 2 ) are constructed and nested in one another.

8.
