Unit for preparation of iced products has the ability to both dispense under gravity and to extract by suction. It dispenses viscous material into successively advancing moulds (15), under freezing conditions which solidify the products. The unit comprises a dosing hopper (3) for the viscous material. It has a filler and suction connection near the top. Below the level of the viscous material, there is a dosing valve for the containers arriving underneath. A control system keeps the product reserve in the hopper between set high- and low levels. The suction line (4) connects via a point near the top of the hopper, above the level of the viscous material, to an external pipette (7) descending into the moulds. The external pipette extracts the still-fluid centre from the moulds and recycles it directly back into the hopper.
