A dropper assembly (10) for feeding liquid composition (20) to a freezing chamber (12) comprises a tray (28) having a plurality of feed elements (40) that are designed to provide regulated discharge of the liquid composition (20) from the tray (28) and to feed the liquid composition (20) into the freezing chamber (12) in uniformly sized droplets (38). The feed elements (40) each comprise a projection (44) that is downwardly disposed in relation to the tray (28). The tray (28) has a bottom wall (30) with a plurality of orifices (42), each orifice (42) associated with a corresponding projection (44). The projection (44) has an inlet opening (48) associated with the corresponding orifice (42) in the tray (28) and an outlet opening (52) where droplets (38) are formed and released. The dimension of the inlet opening (48) is greater than the dimension of the outlet opening (52). The narrowing taper of the flow channel (54) that extends from the inlet opening (48) to the outlet opening (52) promotes regulated accumulation of liquid composition (20) to facilitate regulated discharge and formation of uniformly sized droplets (38). An inventive method is also provided for feeding liquid composition (20) to a freezing chamber (12) to form uniformly sized beads (18) of frozen product. The inventive method utilizes the novel dropper assembly (10).

Cet ensemble d'égouttage (10) permettant d'introduire une composition liquide (20) dans une chambre de congélation (12) comprend un plateau (28) pourvu d'une pluralité d'éléments d'introduction (40) conçus pour évacuer de manière régulée la composition liquide (20) du plateau et l'introduire dans la chambre de congélation (12) sous forme de gouttelettes (38) de taille uniforme. Les éléments d'introduction (40) comportent chacun une partie saillante (44) orientée vers le bas par rapport au plateau (28). Ce plateau (28) comprend une paroi inférieure (30) dotée d'une pluralité d'orifices (42), chacun de ces orifices (42) étant associé à une partie saillante correspondante (44). La partie saillante (44) possède un orifice d'admission (48) associé à l'orifice correspondant (42) du plateau (28) et un orifice d'évacuation (52) où se forment et duquel tombent les gouttelettes (38). La taille de l'orifice d'admission (48) est supérieure à celle de l'orifice d'évacuation (52). La forme conique, effilée, du canal d'écoulement qui s'étend de l'orifice d'admission (48) à l'orifice d'évacuation (52), permet à la composition liquide (20) de s'accumuler avec régularité afin de faciliter ainsi la régulation de l'évacuation et la formation de gouttelettes (38) de taille uniforme. L'invention concerne également un procédé d'introduction d'une composition liquide (20) dans une chambre de congélation (12), visant à obtenir des gouttes (18) de taille uniforme d'un produit congelé. Le procédé de l'invention met en oeuvre le nouvel ensemble d'égouttage (10).
