6. The 3D product production system of claim 5, wherein the freezing unit further comprises a movement assembly coupled to the freezing chamber adapted to drive the freezing chamber to move to different mold positions.

7. The 3D product production system of claim 1, wherein the cleaning device comprises a cleaning spray head disposed above the de-molding device adapted to spray cleaning liquid into the mold.

8. The 3D product production system of claim 7, wherein the cleaning nozzle is formed with a plurality of nozzle holes, each nozzle hole being circumferentially uniformly arranged.

9. The 3D product production system of claim 7 or 8, wherein the cleaning device further comprises a recovery unit adapted to recover the cleaning liquid ejected by the cleaning head.

10. A 3D product production method of the 3D product production system according to any one of claims 1 to 9, comprising:

pouring feed liquid into the mould;

freezing the mold filled with the feed liquid to form a frozen product;

removing the frozen product from the mold;

the mold from which the product has been removed is cleaned.
