Depending on the complexity of the equipment and controls, there are a few options for production personnel to learn how to operate the equipment. The manual explains the operation of the equipment and its components. The customer can visit Apache for training and testing or contract with Mepaco Field Services for on-site training.
In one example, the production staff did not understand how to operate the HD3000 Dumper, causing the carriage to bind-up where cylinders weren't lifting in tandem. The issue was caused by incorrect operation.
Due to the operational configuration of the hydraulic cylinders, the HD300 dumper must be fully cycled (complete cylinder extension and retraction) each time it is used. The production staff was not fully retracting the dumper leaving the carriage 12 - 18" off the ground. This allowed the cylinders to start up unevenly and compounded if the staff did not fully extend the dumper. This caused the dumper carriage to misalign and bind against the dumper frame.
Once the carriage binds against the frame the only way to safely correct the situation is to lock out the hydraulic power unit, disconnect the hydraulic line from the overextended cylinder and allow the carriage to drift down until it is re-timed. Once the cylinders are re-timed the power unit can be operated to bring the carriage to the fully down position. Air will need to be bled from the cylinder that had the hydraulic lines removed.

In the photo, the DP3000 is shown in different stages as the pallet is separated from the combo during the dumping process. This system reduces the risk of foreign matter getting into the food stream and contaminating the food production process.
This dumper also features liner retention which prevents the liner from separating from the combo and falling in the hopper or cart.
In a new system video animation a similar dumper is featured at the start of the Pre-Blend line; shown with safety guarding, the PRS (Pallet Retention System) and LRS (Liner Retention System).
Mepaco’s Pallet Retention System (PRS) is an option on Dumper equipment that reduces the risk of foreign matter like wood and nails from contaminating your food production process.
A manual or optional pneumatic clamp safely secures the combo throughout the dumping process. As the dump cycle begins, the pallet is immediately secured so once the combo reaches 90-deg, the combo can complete the dump cycle apart from the pallet. In addition, a Liner Retention System (LRS) prevents the liner from separating from the combo and falling into the hopper. Upon completion of the dump cycle, the dumper and frame are reunited and the carriage assembly returns back to the start-load position.
This design limits the potential of foreign material from entering the product stream.
The Pallet Retention System (PRS) and the Liner Retention System (LRS) are both available on the DP3000 Pivot Dumper and the HD3000 High Lift Dumpermodels.

Designed and manufactured by Mepaco, this pivot dumper has a high load infeed because of the dump elevation and limited ceiling height available at the customer’s food processing facility. This dumper features a pneumatic combo hold down, with options for additional sanitary surfaces to meet the demands of the caustic and aggressive cleaning procedures.
Due to the high load height, the pneumatic hold-down option allows the customer to use multiple combo/tote sizes in which their IQF (Individual Quick Frozen) products are supplied, without the need for manual adjustment. During the dumping process, the pneumatic hold-down prevents the combo and the liner from falling into the surge loader.
The customer opted for a stainless reservoir tank. Traditionally flat surfaces were redesigned with a pitch to allow water drainage. The top of the reservoir was also pitched to allow drainage.
The application called for all stainless steel piping and non-corroding fittings with a minimum amount of flexible hoses. These upgrades shorten the time to clean equipment between recipe production changes.
All product contact surfaces were electropolished for the greatest resistance to bacterial attachment and the most durable surface for caustic sanitation.
