Embodiment Construction

[0038] With reference to the accompanying drawings, the blowing and filling system for containers according to the invention, generally designated by the reference numeral 1, comprises: a heating furnace 2 for feeding preforms P into the system by means of suitable handling means 3, placed in a heating The blowing unit 4 downstream of the furnace 2, the filling unit 5 with the filling product arranged downstream of the blowing unit 4, and the sterilization unit 6, in figure 1 In an embodiment, the sterilization unit is arranged in the middle between the blowing unit 4 and the filling unit 5 . Thus, in this embodiment, the sterilization unit 6 is adapted to sterilize the containers, usually bottles, leaving the blowing unit 4 .

[0039] The blowing unit 4 and the filling unit 5 are preferably of the rotary type and comprise suitable distribution stars 7, 7', 7" for handling preforms and containers, respectively.

[0040] The blowing unit 4 and the filling unit 5 are of convent...

Abstract

The present invention relates to a system for the disinfection of containers in a blowing and filling system of said containers with a product, in particular a system for the internal disinfection ofsaid containers by means of ultraviolet-C radiation LED emitters.The invention in particular relates to a disinfection unit (6) of containers (C) or preforms (P), characterized in that it comprises acarousel (13) on which there is supported a plurality of disinfection members (8, 108), which are movable between a raised position and a lowered position, wherein said lowered position is configuredso as to allow the disinfection members (8, 108) to enter said containers (C) or preforms (P) to be disinfected, wherein each of said disinfection members (8, 108) comprises a plurality of disinfection elements (20) emitting UV-C radiation or it is connected to a LASER source (102) which emits UV-C radiation or radiation in the visible-infrared field (VIR).

Description

technical field [0001] The present invention relates to a system for sterilizing containers with products in a blowing and filling system for said containers, in particular to a system for internal sterilizing of said containers by means of UV-C radiation LED emitters system. Background technique [0002] As is known, the filling of containers with products susceptible to microbial contamination (e.g. milk and similar products) during the filling step requires a level of hygiene defined as "ultra-clean", i.e. according to class IV standard VDMA 2 / 2000 3rd edition 2016 filling, and is defined as "sterile", ie, filling to class V standard VDMA 2 / 2000 3rd edition 2016. [0003] Currently, the main disinfection systems for containers require the use of oxidizing and bactericidal substances, which leads to many disadvantages, such as: [0004] - risk of residues from sterilization treatments that may contaminate food; [0005] - Risk of contaminating the operator himself durin...
