ABE has designed the GlassPak33 Automatic Monoblock Beer Bottling Systems to meet the needs of the ever-expanding craft beverage market. Built with a heavy-duty stainless steel frame and stainless steel central platform, the GlassPak is ready for action. Monoblock filling systems are robust, continuous motion systems designed to streamline the rinsing, filling, and capping process with minimal valuable floor space.
Bottle Feed Conveyance: Empty bottles are loaded onto an optional feed table or directly onto the main feed conveyor for transportation into the Monoblock station. Pre-rinse: After being conveyed into the Monoblock unit, bottles are automatically inverted, rinsed, and drained to release any debris that may have accumulated during bottle transportation or storage. In this phase, the continuous motion design grabs and inverts each bottle and positions it over an internal rinse nozzle spraying water, or sanitizer solution, inside the bottle. Typical installations use tap water for pre-rinsing and then run the used water to a drain. The GlassPak also comes with a recirculating pump that allows the producer to recycle a sanitizing rinse solution. Please speak with your ABE representative for rinsing options.
Bottle Filling: The GlassPak33 is a 12 head (18 head for the GlassPak66) counter-pressure style bottle filler with double-pre-evacuation. Each head performs four main functions during the filling process: removing the majority of air from the empty bottle, purging and pressurizing the bottle with carbon dioxide, filling the bottle with beer under pressure, and relieving the pressure and releasing the bottle to complete the filling process. After rinsing, bottles travel to the filling station, and a vacuum maximizes oxygen removal. When the fill valve is open, Carbon Dioxide-CO2 replaces any air at an adjustable pressure of up to 40 psi. This process helps to ensure low dissolved oxygen carryover, which increases shelf life and maintains quality. Once bottles have reached the same internal pressure as the filling drum, a spring-activated device allows the liquid valve to lift from its seal and initiate the filing process. A predetermined fill-vent tube length limits the fill level of each bottle. The lower this tube protrudes into the bottle, the lower the final fill level position. Once the rising liquid reaches the vent tube, it travels up the tube until it reaches equilibrium with the liquid in the drum, forcing all liquid movement to stop. The filling valve is then closed, an exhaust port is opened, and the bottles are "vented" until there is no longer counter-pressure inside each bottle. After this process is complete, bottles travel to the capper where a crown cap is automatically applied (other capping options available).
Capping: The capping portion of the system elevates bulk caps (the hopper will hold up to 5,000 crown caps) from the hopper to the cap unscrambler. The unscrambler tumbles caps in a protected chamber that directs them to the main cap chute assembly with the open side up. At the bottom of the chute, a small air stream blows each cap into the capping position in preparation for proper application. As bottles pass under the chute, caps are applied by way of a hysteresis capping head ensuring ideal torque release and a well-capped bottle.
