Laboratory infrared pre-treatment system

LAB InfraRed

Equally effective as its scaled-up counterpart, our LAB IR is specially designed for optimal pre-treatment of cocoa beans, preparing them for efficient nib-shell separation.

Key benefits

Maximize yield of the complete LAB process
The moisture content of the cocoa nibs remains constant during infrared pre-treatment, limiting fine generation and ensuring you achieve a top yield in the separation of the shell from the nibs regardless of origin.
Achieve quality through prevention of roasting effects
The low penetration depth of the infrared treatment prevents product altering effects like early roasting. The drying process never exceeds product altering temperatures, allowing for pre-treatment without the risk of heat damage.
Efficient treatment thanks to integrated water spraying system
The LAB IR's integrated water spraying system allows the moisture content in your cocoa beans to be matched to the infrared treatment, allowing even the most difficult cocoa beans with a high shell content to be pre-treated with maximum efficiency.

Highlight features

Innovative processing solution

Intentional design for optimal processing

The LAB IR embodies an insulated rotating drum with conveying spiral and deflector pins to ensure a homogeneous product flow. Water injection systems improve the cocoa shell detachment, in case of low-moisture content.

Short heat impact

Protecting taste characteristics

The short heat treatment of the infrared pretreatment process reduces the breaking energy, preventing fat transfer from the bean surface to the shell. This reduces taste impact on your cocoa, giving you more control of your chocolate flavor.

Safe and hygienic operation

Closed construction protects you and your product

A completely closed construction and aspirated machine parts enable the safe and clean operation of the LAB IR. Due to the closed system, possible contamination is also prevented during processing.
