Roasting Procedures
PROBAT offers the following roasting procedures:
• Drum roaster (type L, G and R)
• Centrifugal roaster (type RZ)
• Tangential roaster (type RT, RN, Gothot)
• Continuous roaster (type RC)
• ThermaTwo 1200
Units
But you usually need more than roasting machines for professional
coffee refinement. For this reason PROBAT provides
solutions starting with the small-scale gourmet roaster and
ending with plant components required by the large companies
of the coffee industry and aligned with their needs.
Such components include various conveyor systems like
conveyor belts and bucket elevators as well as pneumatic
solutions such as high-suction conveyors, suction-impulse
conveying units and high-pressure conveyor units. On the
side circular sieve cleaners, air cleaners and metal separators
provide for a thorough cleansing of green coffee.
For green coffee blends undertaken on the basis of „blending
before roasting“, a blending scale component is available.
Further expedient components such as briquette and pellet
presses for compacting the chaffs ensuing during roasting,
stone separators, conveyor systems and roasted coffee silo
units are available for post-roasting processes. Roasted coffee
scales serve to compose roasted coffee blends („blending
after roasting“) as well as for documenting silo inventories.
Finally, there are ground coffee silos for a pure-grade
storage of the ground coffee.
Controls
PROBAT offers controls for roasters, mills, and whole roasting
units which can be combined to an overall solution. The
existing computer control was redeveloped and sets new
standards in terms of operator convenience and user interface.
Mills
Roll mills range from about 50 up to 5,000 kg per hour. Rolls
are standard equipped with special fluting; depending on the
model, supplementary equipment such as infinitely variable
roll adjustment for attaining any degree of grinding, watercooled
grinding rolls, integrated permanent magnet and turbo
mixer is available.

Service and Training
PROBAT’s service programme extends beyond assembly,
maintenance, repairs and the fitting of spare parts. PROBAT
also carries out in-house training. This could be a product
training or a training imparting coffee knowledge. Moreover,
individual on-location training at the customer’s roasting
unit is possible at any time.
Spare Parts
Spare parts for PROBAT’s units, roasting machines or grinders
can often be provided even for equipment that is older
than 50 years. On request and as far as possible they can be
tailored to the individual needs of customers.
Environment
Of course, all PROBAT units conform to the respective stringent
laws and environmental regulations. Depending on the market,
different requirements for the treatment of exhaust gas
apply. Besides the prevalent systems such as afterburners or
catalytic converters, PROBAT offers a technology called Proforte
that cleans exhaust gases using a non-flame and regenerative
thermal oxidation process and thus no longer requires
an additional blower burner – which means saving energy.
