The project

Cramer-Mühle KG in Schweinfurt invested in the extension of its production line. For the transport of grain and flour as well as the extraction of dusts, the company employed the reliable modular tubing system of JACOB. The production and storage systems of the Cramer mill reflect, thanks to modernization and new machines, state-of-the art technology. The grain mill has a production capacity of 800 tons per day. In the large grain silos with a storage capacity of 30,000 tons, the various quality grades are stored separately and milled separately.

The Design

During the extension project, the JACOB tubing were used in a major portion of the plant. Cramer especially appreciates the easy installation of the modular tubing system. As a result, the installation and dismantling for maintenance and cleaning purposes is achieved quickly, reducing the time of production interruptions. Thanks to quick-acting clamping rings and border sealing rings, this is one of JACOB’s special area of competence. As Cramer works with hygiene-sensitive products, the quality requirements for the tubing system are correspondingly high. Thanks to a high-quality stainless steel design, JACOB tubing systems offer a perfect solution likewise in this area.

The Special Feature

JACOB tubing systems are used on the premises of Cramer mill in view of the high-quality standards. As the handling of food is concerned, components of high-quality stainless steel were used exclusively. In addition, materials with a high corrosion resistance are required in the food industry to enable their thorough cleaning and disinfection. Also in this context, the high-quality stainless steels of the JACOB tubing system proved successful. With the electrically conductive EPDM border sealing rings, the transport tubing was equipped according to ATEXstandards and the electrostatic charge is removed in an uncomplicated manner.

This prevents the risk of a flour dust explosion. The selected lines were designed in the diameter range of DN 120/150 millimeters to DN 200 millimeters of stainless steel and have a wall thickness of one to three millimeters. The two millimeter thick tubing system is 3 bar explosion pressure resistant in connection with the easy-to-install QUICK CONNECT clamping rings. The complete system based on a modular assembly principle of tubing components and molded parts covers an overall length of 1500 meters
