PreFiner S G™ 900 / 1300 / 1800

This semi-automatic two-roll refiner has been developed for mid-size to large production lines with a high level of automation. It enables a broad range of chocolate, filling, and coating masses to be pre-processed, in particular specialty masses such as crumb or extremely fluid batches. The output product has a reproducible plasticity and a fineness ranging from 70 to 250 microns with a narrow particle size distribution. This Bühler prerefiner is available with three roll lengths: 900, 1300, and 1800 mm. Flexible gap setting for input plasticity without limits.
Thanks to high-precision, automatic roller gap setting, this PreFiner S G™ also allows difficult products such as extremely fluid or very dry masses (crumb) to be processed. This ensures maximum flexibility.

Optimal product fineness and plasticity thanks to adjustable machine parameters.
Thanks to the broad range of roller gaps which can be selected in small increments, a wide variety of products can be processed. The reproducible recipe parameters guarantee optimal matching of the product to the downstream five-roll refiners. This enables an end product to be obtained with a consistent taste and fineness.

Process optimization for top production efficiency.
The process zone is optimally matched to the customer’s specific product recipes. Customized specification of roller speed differentials and roller crown enable maximum throughput rates of up to 15t/h to be achieved with the required fineness. On this machine type, the capacity can be variable adjusted to the performance of the five roll refiners. The high shearing capacity releases a maximum amount of the bound fat while at the same time calibrating the crystallized sugar. The result is a homogeneous product and an efficient process.

New standard in hygienic design and efficiency.
The PreFiner S sets new standards in hygiene, accessibility and maintenance friendliness. A new hygienic concept with optimized spaces facilitates and accelerates cleaning. The optional stainless steel process zone increases the standard additionally.
