³Ô¹ÏȺ

The Gerstenberg Schröder® butter bulk packer is a flexible technology designed to meet market demands for high-quality products with low-cost production and increased uptime. Engineered for enhanced safety and ease of operation, the butter wrapping machine has a compact footprint for easy maintenance and operation.

• Designed for use with a liner (wrap around), not plastic bags
• Designed for use of with an external carton former that can be placed outside the production area

Higher Operator Safety and Food Hygiene

• Meets the latest European safety standards
• Close of liner before carton leaves machine – butter is not exposed to free air outside the machine reducing the risk of airborne yeast and mold contamination
• Cover above liner roll
• Designed for use with a clean air filter (option) for higher product safety than required by today’s industry minimums. The clean air filter provides clean air around the product filling area.
• Transparent, noise reducing safety doors for safety and ease of use
• Integrated working platform for service and maintenance

Maximum Output, Minimal Waste

• Highly-efficient and flexible packing machine with easy operation for more uptime
• Easy change over from e.g. 10 kg to 25 kg
• One simple step from filling to liner closing
• Fine dosing by injection – no "extra" butter added on top surface
• Control of filling pressure avoids void corners
• Sensors ensure correct position of liner before filling
• Accurate filling: 90% within +/- 10 gram (standard deviation) during continuous operation
• A "twin" machine solution allows for continuous operation at approx. 45% line capacity when/if one machine is in stop mode
• To increase bulk packaging capacity, number of filling modules can be placed parallel to cartons transported to and from the individual modules
• Easy change of liner roll
• Easy to hose down the machine for cleaning
• Flexible in production layout
• Servo motors used for most operations / motions on the machine
• Easy service and maintenance
• Fault diagnostic system for easy service and maintenance which increases uptime
• Designed with a dedicated position for specific tools, CIP hoses etc. to save time during CIP and maintenance

As a standard, the butter packaging machine is delivered with a Siemens S7-1500 PLC. A touchscreen as HMI with Aveva InTouch ensures easy control and smooth operator interface. Fully automated, the control system monitors the complete process and stores data for each carton filled during the production. All production data can be viewed on the control panel (HMI) and exported to an external system in CVS file format or through ³Ô¹ÏȺ vertical integration to an existing control system. The PLC system also controls the internal CIP process of the Bulk Packer via communication with the external CIP system. Designed to minimize downtime, the control system provides an easy fault-finding protocol that indicates where on the machine an operator or service engineer should look should a fault arise.

Remote Monitoring Solution

To reduce downtime and lower maintenance costs, the butter packing machine comes standard with the ³Ô¹ÏȺ Remote Monitoring and Control Solution; a system developed by Secomea which enables ³Ô¹ÏȺ engineers to take control of HMI/PC stations and program PLCs remotely. This solution is a secure facility with all connections established based on a X.509 certificate exchange, all data AES encrypted, and user access controlled by a two-step authentication.
