and consistent yield, Bühler optical sorters meet the

requirements of small, medium and large processors.

Solutions are offered for all kind of coffee beans such

as roasted coffee, semi/fully washed, sun dried, green

Robusta and Arabica coffee.

Bühler's commitment to substantial investment in R&D

ensures that its advanced optical sorting technology of

the Bühler optical sorters produce excellent results in

removing even the most challenging coffee defects.

2 Coffee Optical Sorting

Sorting solutions

Bühler offers flexibility to coffee processors, for whom precision sorting will improve product quality and process

efficiencies, across a wide range of applications.

Key Benefits

� Setting exceptional standards of quality and safety

� Maximising the value and yield

�Consistent performance and stability

� Increased productivity and lower operational costs

� Multiple, configurative machine options

Colour sorting (Ordinary, Specialty, Sundried)

Optical sorting can remove colour defects providing a

cleaner product. Defects from Arabica coffee include

black, brown, vinegar, white, yellow, foxy bean (reddish)

and Broca. In Robusta coffee, light, black and greenish

defects, caused in the specialty process, are removed.

Foreign material sorting (Ordinary, Specialty, Sundried)

Optical sorting can remove FM which has been

missed, or not targeted by the mechanical cleaning

process, achieving optimum quality. Defects include

sticks, stones, glass, shell and others caused by the

fermentation process such as sour/vinegar beans.

Colour sorting

Optical sorting can separate out under or over-roasted

beans, on the basis of colour. Targeting the under-

roasted beans (lighter or white), immature beans,

ensures a better taste and quality.

Foreign material sorting

Foreign material in roasted coffee can be the

same colour as the good product, especially

sticks, stones and glass. If undetected, it can

compromise the appearance of the final product

and can also damage mechanical equipment such

as grinders.

Setting exceptional standards of product quality and

safety

� Bühler optical sorting solutions deliver high efficiency

in the removal of subtle colour defects, including

Broca (insect damaged), discoloured, immature,

under/over roasted beans, to achieve optimum roast

and ground quality

� Excellent results can be achieved in removing even

the most challenging defects such as sticks, stones,

metal, glass and other foreign material, to maximise

safety

Maximising the value and yield

� Precise optical sorting achieves uniform appearance

for a superior quality of yield

� A range of advanced custom-built technologies

ensure the selection of the highest quality of coffee

beans. These include LED and Broad Spectrum

Lighting, MultiVision/ColorVision, PROfile and InGaAs

(NIR/SWIR) technology

Roasted Coffee (foreign material sort)

PROfile Technology

PROfile technology can intelligently detect and virtually

separate touching coffee beans, allowing for a higher

capacity shape sorting. Another added feature of the

PROfile technology is the capacity to use a combination

of multiple shape parameters to remove FM such as

same colour sticks and stones from both green and

roasted coffee.

LED Lighting

The SORTEX A MultiVision range offers a high intensity

solid state LED lighting system. Energy efficient and

durable, Bühler's LED system generates less thermal

heat but still produces more light, resulting in sorting

consistency over a longer period of time.

Visible Cameras

Bühler’s cameras are designed and built in-house to

meet customers' specific needs. High resolution optic

sensors deliver the colour registration needed to detect

the most subtle colour defects. When combined with

InGaAs technology these sensors allow SORTEX optical

sorters to detect many commonly found foreign materials

that compromise the appearance and cleanliness of the

end product.

InGaAs Technology

InGaAs (NIR - Near Infra-Red/SWIR - Short-Wave

Infra-Red) technology detects a wider range of

contaminants than previously possible and is particularly

effective in identifying the most challenging of coffee

defects. It provides much better separation of good

product from foreign material of the same colour, in

comparison with a visible camera.

SORTEX Customer Care.Secure tomorrow’s profits today.

Solutions and support to ensure that your optical

sorter is performing to maximum efficiency, delivering

maximum productivity and making a maximum return

on investment.

Bühler’s worldwide Customer Care organisation delivers

the highest quality local support by offering a variety of

services under SORTEX Total Care*.

* All contracts are available for different durations

SORTEX Total Care

SORTEX Total Care offers customers the opportunity

to create their own service package, composed of

individual service features, to best suit their needs.

Customers have the flexibility to create their most (cost)

effective programme - whether that covers just those

areas of prime concern, or a fully-comprehensive cover.

Comprehensive cover is suitable for customers who

require continuous operation of the optical sorter where

the processing line is of the utmost importance. This

way, customers can ensure that their investment is fully

protected.

Customers can tailor their individual package from the

following options.

• WearCare - Preventative Maintenance

A fixed number of visits per year. During the visit

an engineer will carry out checks, adjustments and

when necessary replace consumable or wear parts.

• RepairCare - Emergency Repair

In the unlikely event of the machine failing, an

engineer will visit and repair the optical sorter.

• EjectorCare - Ejector Service and Repair

When the ejectors reach their refurbish point an

engineer will visit to replace the ejectors with the

appropriate number of units for the whole machine.

• AnywareCare - Anyware Health Check

and Alerts

The Anyware system allows the performance of

optical sorters to be monitored remotely.

This diagnostic system facilitates a quicker

response to any issues that might emerge. It

automatically emails an alert message to the server,

if an optical sorter develops a fault, or begins to

operate outside normal working parameters.

An authorised engineer reviews the information

in the alert, and advises whether adjustment is

needed, or if the problem needs further attention.

SORTEX Spares Kits

For customers who require spare parts available on site, Büh-

ler’s technologists have created appropriate spares kits for the

different machinery available.

SORTEX Upgrade Kits

Customers seeking the latest technology available on their

optical sorter - whether software or extra functionality - benefit

from a range of upgrade kits available.
