Administration system comprising administration material cooling apparatus

摘要

The invention relates to a dosing system (1) for a dosing material, comprising a dosing device (5) with a housing (11), wherein the housing (11) comprises a feed channel (80) for the dosing material, a nozzle (40), a discharge element (31) and an actuator unit (10) coupled to the discharge element (31) and/or the nozzle (40). The dosing device (5) also comprises a dosing material reservoir (70) which is coupled to the housing (11) or integrated into the housing (11). The dosing system (1) has a plurality of temperature control devices (2, 2', 2'') which are respectively assigned to different temperature zones (6, 6', 6'') of the dosing system (1) in order to control the temperature zones (6, 6', 6'' ') differently. At least one first temperature zone (6) is assigned to the dosing material reservoir (70) and at least one second temperature zone (6'') is assigned to the nozzle (40). Preferably, at least one of the temperature control devices (2, 2', 2''), preferably at least the temperature control device (2) assigned to the dosing material reservoir (6), comprises a cooling device (3, 3', 3'') having a cold source (93, 93', 95, 99).
