COVER STORY
Sipac accumulation table between filler/corker and capsuling machine
Bertolaso capsuling machine
A ring bowl (AISI 304 stainless steel) minimizes wine turbulence and has a bottom that is sloped to allow complete drainage of the liquid during the washing stages or emptying of the bowl. The lid is locked to the bowl mechanically by means of outer locking screws that are not in contact with the wine.
Filling valves are fully constructed of AISI 316 stainless steel. The fill height in the bottle is obtained by a quick adjustment of the threaded sleeve permitting a regulation up to 50 mm. Centering cones are fitted to the filling valves to permit a perfect centering of the bottle under the filling valves before the fill tube enters the bottle neck.
Liquid feeds from the bottom controlled by a pneumatic valve controlled by the level control probe. The product flows into the bowl through AISI 304 stainless steel tubes and is conveyed into the bowl by means of a rotary distributor. The section and the geometry of the tubes and the rotary distributor, as well, are sized to reduce the shaking and the flow speed of the liquid to the minimum possible thereby permitting the necessary stability of the product. A conductive probe cntrols liquid in the bowl at a constant level, thereby permitting a controlled and gentle feeding of the product.
The system to protect the wine in the bowl from oxygen pick-up includes an inert gas blanket that is created to prevent air/wine contact in the filler bowl. The air is removed from the bottle and canalized into a separate circuit. The system is complete with pressure regulator, pressure gauge, and system for inert gas injection into the bowl.
A system automatically performs the CIP function by PLC including automatic insertion of the stainless steel cups on the filling valves and centering cones without manual intervention.
JFW inserts natural corks into bottles of red wine while white wines receive natural corks or synthetic closures, and 375ml bottles receive screw caps.
Bottle conveying line from filler to capsuling machine (above) includes a Sipac accumulation table designed to handle three minutes of accumulated bottles, should there be a problem with the capsular or labeler. This gives the operator enough time to fix the problem, without taking up valuable floor space with “miles” of conveyor.
One Bertolaso Rotary Monobloc ZETABLOC 10B/18R Capsuling Machine (above) was installed downstream from the new filler that dispenses and spins tin or polylaminate capsules at a maximum speed of 300 bpm. The machine has eight feeding-cups and 18 spinning/ smoothing heads.
Important features of this machine include: a long autonomy capsule magazine to hold approximately 15,000 capsules with drawers that can accept 725 mm long sticks, an automatic loading arm, and a horizontal flat belt conveyor to feed capsules into the
dispensing unit. The capsule dispensing module has two parallel horizontal troughs and mechanical fingers separating the capsules from the stick as they approach the dispensing cups on the application turret. Air blows the capsules onto the bottles.
The capsules are an aluminum/ poly/aluminum laminate supplied by Maverick Enterprises, Inc.
One Bertolaso Accumulation Table automatically rejecting bottles with no capsule is located just after the Bertolaso capsuling machine. The table is composed of five-lanes, 2,000 mm long, complete with drive and return heads, motor, and chain in AISI 430 stainless steel.
The Krones Autocol rotary labeler (below) which is designed with a 720-mm diameter bottle table and 15-bottle plates and two labeling stations applies body front and body back pressure-sensitive (p-s) labels to three different styles of bottles. With a rotary labeler, bottles are firmly held and centered between the bottle plate and a spring-loaded centering bell.
