Description
The KRF-31 is a multifunction machine that includes a device for rinsing of stainless steel kegs with- one position for a keg. The equipment is designed for the rinsing of kegs for beer, cider, wine and for other beverages, using semi-automatically operated valves and a pump.
Operating capacity : from twelve up to twenty kegs per hour (rinsing and sanitizing).
Basic features:
- The machine is made of stainless steel 1.4301 / AISI 304
- The electric switchbox is made of lacquered steel sheet, optionally stainless steel (for surcharge)
- Operation place for KEGs is made of polyethylene, plate thickness 20 mm
- Connections of the KEGs with machine are made with the food hoses and the connection fittings
- Pneumatically operated stainless steel piston valves with PTFE seals
- Isolated 80 liter detergent tank with electric heating spiral and level sensor
- Electric, steam or combined heating of the detergent – caustic or alcalic solution
- Adjustable stainless steel feet for machine balance
- Control via buttons, adjustment via color touch screen
- Sensors to check the correct function of the machine
- Components from world leading manufacturers (Siemens, Endress + Hauser, Sensit, etc.)
Features :
- The machine is designed to the intensive rinsing inside of the KEG barrels
- Performance from 12 up to 20 KEGs per hour *)
- For all types of coupler fittings (A, D, G, M, S, U, Flat, Corb, Combi, etc.)
- For all KEG sizes (volumes from 15 to 50 liters)
- Alternate rinsing of walls and coupler fittings of KEGs
- Automatic checking the correct function of the machine
- Detergent quality monitoring (based on the number of rinsed KEGs)
- Built-in 80L tank for one chemical deterent
- Two washing programs, the intensity of rinsing or filling can be adjusted
- Washing statistics
*) The performance of the machine depends on the actual settings of the the keg washing process
Technical parameters :
- Power supply – 400 VAC
- Power consumption – 9 kW, of which 8 kW electric heating
- Volume of the built-in detergent tank : 80 liters
- Dimensions – w x h x d – 900 x 1850 x 800 mm
- Weight – 165 kg
How the machine works :
Rinsing-sanitizing program :
- Check the correct KEGs connection
- Draining of rests from KEGs
- Rinsing of the walls and fittings with cold water
- Blowing out the cold water residue with sterile air
- Rinsing of the walls and fitting with hot detergent
- Blowing out of the cleaning solution from KEGs with sterile air
- Rinsing of the walls and coupler fittings with hot water
- Blowing out of rinse water with sterile air
- Blowing of the KEG with sterile steam
- Pressurizing of the KEGs with sterile steam
- Sterilization inside space of the KEG
- Blowing out steam residues with CO₂ / N₂
- Pressurization KEG with CO2 / N2
- Sound signal “End of rinsing”
