Food / Pet Food Processing Applications: Pet Food Processing
Details: Packaging. After the extrusion and drying step the product is cut, dried and weigh metered prior to feeding to the packaging line. Process: After the dried product is weigh metered, it is often times sprayed with liquids prior to going to the packaging line. The addition of these liquids can

Getting to know stepper motors
and amount, are controlled by stepper motors. Electronic pipettes are linear-stroke devices that utilize digital linear actuators to precisely control the amount of fluid being dispensed. The shaft of the actuator is coupled to a pipette fitted with a piston. A microprocessor controls the step rate

Chemical Processing Applications: Laundry Detergent Production
. After mixing, the detergent powder passes through a final sieving and metering stage. In the final step, a Smart Weigh Belt transfers the finished product into the packing operation. There it flows directly to a packing machine, tablet press or into FIBC's for intermediate storage or bulk transport
