Case Story: What can happen when an agitator problem is ignored? A high-volume pet food processor utilized a Mixer/Cooker in their operations which produced 45-minute batches. The application called for 28 RPM and mixing cold product at 35 – 45 degrees. During the process of loading different ingredients into the Mixer-Cooker, a Vmag buggy fell into the mixer, causing damage to the agitator. The processor made repairs to the bent shaft and paddles and was able to get the Mixer-Cooker back online into full production. Many processors assume that if the paddles do not rub the side of the tub, that the agitator has had a successful repair. But in many cases (and in this case), there was extensive damage and over time the shaft began to flex, causing the agitator to break. This failure completely stopped production. There are a few choices to stay ahead of agitator care: Preventative Maintenance: Partner with Mepaco Services to inspect agitators to ensure the shaft is straight and look for stress and other damage. After Event Care: Processors may be able to fix the shift to continue production, but contract with Mepaco Services to inspect the shaft and straighten if necessary. Most importantly, processors should avoid emergency maintenance, causing down-time and lost production. It is not uncommon to have dropped tools into Mixers, so prepare for the event if it does happen. Consider an audit to assess the life of the agitator and consider ordering a replacement so you can have duplicity for uninterrupted down-time. Delivery of agitator replacements are 3 – 6 months out due to the availability of stainless material. Mixers, Blenders and Grinders are the work horse of the processing system, so be sure that agitator care and component availability are part of the maintenance program. Mepaco Services offer on-site audits, training, and service contracts as well as emergency repair.
