Guardian® Series 2 Batch Gravimetric Blender
Guardian® Series 2 Batch Gravimetric Blender
The Guardian® Series 2 gravimetric batch blender was developed for processors who want the simplicity of operation combined with the most accurate dispensing and superiour blend homogeneity at a low cost. For these customers, Process Control designed the Guardian® Series 2 blender with redesigned material hoppers to hold each of the ingredients in easy to clean material hoppers with no opportunity to hang up and contaminate blends when changing materials.
Each hopper has one 90° degree side an no transition sections for improved material flow. The hopper access doors have a secure latching system. Cartridge sale dispensing gauges with only 4 bolts to remove allow for easy of maintenance and rapid clean out. Optimized V-design metering gates provide improved accuracy and dispensing range. The control interface is via a 150 mm (6 inch) colour touch screen with ‘off-the-shelf” industrial controls. Remote communications is via the Ethernet port and supports standard industry protocols.
All Guardian® Series 2 gravimetric batch blenders come equipped with a fast acting V-gate valve for the material hoppers. Each of the materials is dispensed sequentially into a common weighing hopper in the desired proportions. The weighed materials are then released into a separate mixing chamber which provides the most consistent homogeneous blend of any batch type blender. Process Control engineers have developed a highly advanced dispensing and weighing system that accurately controls each ingredient of every batch to the desired amounts and is not averaged over multiple batches as is common in other batch blenders in the industry. At the blender’s most precise setting, each ingredient can be dispensed to an accuracy of ± 0.02%.
