FOOD LINE “With the H1 certified FOOD FLUID 46 from MOTOREX we’re on the safe side!” Beat Hubmann, Head of Production, RAMSEIER Aachtal AG With two powerful new juice presses, RAMSEIER Aachtal AG (CH) heads into juice season 22. Specially developed food industry hydraulic oil FOOD FLUID 46 has an important job to do in the hydraulic system. SAFE AT WORK FOOD FLUID 46: AN EXTRA PORTION OF SAFETY Each year RAMSEIER Aachtal AG (CH) processes up to 60,000 tonnes of cider fruit in just under three months. Key to successfully processing the harvest are two new, extra-powerful hydraulic filter presses. The presses are filled with H1-registered, food-safe FOOD FLUID 46 hydraulic oil – testimony to the stringent quality and safety commitments at Switzerland’s biggest juice bottler. 7,500 L PRESS CHAMBER CAPACITY The BUCHER HPX 7507 can handle a wide range of solid -liquid substance separation tasks. At RAMSEIER Aachtal AG, two of these powerful modern machines process between 18 and 24 tonnes of apples and pears per hour into freshly pressed juice. A piston-and-cylinder system presses the fruit through a series of drainage elements (filters) in several cycles. Each machine’s press chamber capacity is an imposing 7,500 liters. Once the pressing process is done, the pulp residue is automatically emptied. A self-optimizing press control system determines the product’s pressability at each stage of the process and continually adjusts the process parameters for maximum throughput and yield. RAMSEIER AACHTAL AG Various factors can cause harvest sizes to fluctuate widely from year to year. RAMSEIER Aachtal AG’s maximum daily processing capacity is roughly 1,000 t of cider fruit, yielding about five million liters of freshly pressed juice per week. At the height of the harvest, from mid-September to late October or so, production takes place in shifts around the clock. The company processes some 40 % of all cider fruit in Switzerland. Sophisticated processes and high reliability of both infrastructure and personnel are needed each year to ensure successful processing of the harvest. MOTOREX FOOD FLUID 46 plays an important role in the process that creates the unmistakable RAMSEIER fruit juices. • MOTOREX’s specialization in lubrication applications an H1 fluid is a precautionary safety measure.
