4-Head Manually Loaded Cask Washer
Once the external wash and label removal process is complete the cask will be taken of the conveyor system and place on the cask internal washer system with steam heated 1000L hot water tank.
The cask internal washer machine is a proven design the operator will place 4 x empty casks on the washing
head.
1st stage pre-wash of casks
This is done with recovered and stored hot sanitization water in a pre-wash tank,
Pre-wash to drain and the second stage pre-wash recirculates the water and removes debris.
2nd stage Pulsed Washing
Works on a pulsed washing system
This is achieved by timing a pulsed wash, the casks can drain between power pulses to provide an effective clean. Cleaning needs the high-power jet at 6 bar pressure and removes the debris from within the cask with a rotating wash nozzle.
3rd stage Hot Detergent Wash
The main wash with hot detergent normally around 70ºC but is adjustable. This is directly heated by either electric immersion heater steam within the 1000 litres tank.
Temperature is controlled via a transducer connected into the HMI screen local to the washing unit.
On the HMI screen, temperature and alarms can be adjusted and set up to the desired wash paraments. Once set the system will run automatically there is a detergent tank located in the machine and mixture levels can be set.
4th stage Final Hot Sanitization Rinse
Process of hot water final rinse sanitization. Sterilized hot water at 4 bar pressure to serve as final rinse to
sanitize the cask; the process is designed to get the casks internal surface up to above 80ºC by injecting hot clean water at a temperature of between 85 to 89ºC.
Mobile gravity transfer
After washing the casks are to be removed and placed on the mobile gravity roller track. This track allows free movement of the empty casks and kegs in the area, so they can be transferred to the filling zones. A keystone press will be incorporated onto this
Twin Head Racker with Shive Press
The operator loads the empty cask onto the racker bed, locates the bung hole of the cask to the fill head then presses the start button to initiate the automatic meter filling process.
The cask shive insertion will be automated along with the shive press station, once the cask has the shive
sealed and in place the cask will automatically move forward on the powered conveyor system to the next
process.
Discharge unit
Full sealed casks will be discharged onto the powered twin stand chain conveyor.
The cask will be dispensed onto the chain conveyor by means of a pneumatic cask arrester.
