PROBATONE 5
Type of system: Shop roaster (batch capacity of 3-5 kg)
Kind of system: Drum roaster
Field of application: Roasted coffee
THE ESSENTIAL ADVANTAGES OF THE PROBATONE 5 AT A GLANCE:
Homogeneous roasting of the coffee
.
with Probat-specific product-air ratio
and special shovel mechanism
Quick, gentle cooling of the roasted cof-
fee by a large cooling sieve and even
distribution with food-safe plastic scrap-
ers
Cleaning brush underneath the cooling
sieve removes bean particles and chaff
Classic, nostalgic design by many com-
ponents made of high-quality cast iron
Reduced cycle time by simultaneous
roasting and cooling with separate ven-
tilators
Efficient drive concept by separate mo-
tors for drum drive, cooling sieve stirring
arm, as well as, roaster and cooler fan
Greater flexibility during roasting by
adjustable gas regulation
Efficient heating by proven burner tech-
nology
Simplified cleaning by removable side
walls
Separate roasting cyclone for an effec-
tive chaff separation
Accurate operation with digital time and
temperature display
Hand-crank for emptying the roasting
drum in the event of a power outage. Al-
ternatively, a supplied adapter makes it
possible to attach a cordless screw-
driver to simplify discharging.
