WP Kemper – Bakery Technology from Rietberg
WP Kemper GmbH in Rietberg is part of the WP BAKERYGROUP and is the competence center for dough production, small pastries, and fried pastries. The company develops, builds, installs, and services machinery and systems for bakeries – from stand-alone mixers to fully automatic kneading systems, lifting tippers, dough portioning and forming machines, bun and bread lines, up to donut and fried pastry systems for industrial boiled pastry production. The products are manufactured entirely in-house; components and system parts consist predominantly of stainless steel, partially of painted steel and plastics. In addition to machine manufacturing, WP Kemper offers turnkey project solutions for entire industrial baking processes, including design, installation, and commissioning. Test demonstrations, training, and process consulting by master bakers take place in the company's bakery center in Rietberg. Service offerings include ProductionCare, preventative maintenance, digital-based monitoring (WP CONNECT), spare parts supply including 3D printing of molds and spare parts, as well as the 24/7 service line. Customers include artisan bakeries as well as large-scale bakeries and the bakery industry; systems are delivered worldwide through the foreign representatives of the WP BAKERYGROUP.
