Video: Top 10 Dumper Safety Innovations

Thu, 12 Oct 2023 15:17:40 GMT

In the interest of food safety and personnel safety goals across food processing customers, Mepaco has innovated options to solve these goals. Dumpers are a part of nearly every system and can be the first process in an automated solution. With automation comes food safety and personnel safety issues that these options and features on dumpers, can address. Here are Mepaco’s Top 10 Dumper Safety Innovations:

1. PRS (Pallet Retention System)

The PRS design limits the potential of foreign material entering the product stream, by separating the combo from the pallet in the dump cycle. Upon completion of the dump cycle, the dumper and frame are reunited, and the carriage assembly returns to the start-load position. PRS is available on the DP3000 Pivot Dumper and the HD 3000 High Lift Dumper models.

2. LRS (Pneumatic Liner Retention System)

The LRS controls a device that prevents the liner from separating from the combo and falling into the hopper and food stream. The liner hold-down prevents operators from having to reach and try to control the liner by hand. LRS is available on the DP3000 Pivot Dumper and the HD3000 High Lift Dumper models.

3. Elevated Load Height

Elevated load heights are specified in layouts that may have limited ceiling height available. Whether it benefits production or personnel maneuverability, elevated load heights can be customized into the dumping equipment solution. Elevated load heights are commonly added to DP3000 Dumper models.

4. Stainless Cylinders

Upgrading cylinders to stainless will provide sanitation performance and longevity. Depending on the sanitation protocols, it may extend the cylinder replacement parts rotation.

5. Counterbalance Valve

Counterbalance Valves are engineered for cylinders to safely hold a dumper carriage with load. The counterbalance valve uses back pressure from the power unit to open and bring the carriage down. In the event of a hydraulic line rupture, the carriage will hold in position.

6. Electropolished Chute

Electropolished food contact surfaces help with high food safety standards in a processing environment. An electropolished chute will support efficient sanitation that is cleanable to a microbiological level.

7. Beacon Light

Adding a signaling light alerts faults in applications where safety is an issue. There are several options for Beacon Lights, this video shows a model with a horn.

8. Safety Guarding

Personnel guarding can also be designed for the entire dump-zone footprint. Guarding is engineered for the plant requirements. Another configuration is a pocket door design that allows for safe fork truck access for loading and unloading.

9. Automation & Controls

With a full safety enclosure and controlled dumper system, the load set point, detraction, and down control can be integrated into the HMI (Human Machine Interface). The dump function can also be automatically timed to feed downstream equipment using loss-in-weight or level sensor technology. The safety enclosure can also be designed and controlled to open automatically for loading and pallet removal.

10. Safety Training

If you have operators who are unfamiliar with dumper operation, please inquire with field services and parts. When followed, Mepaco’s manuals, media resources and even a training program if required, will help with the safe operation of your dumper equipment.

Proper Operational Procedures Improves Dumper Performance

Tue, 08 May 2018 17:41:00 GMT

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.

Please call Joe Hertel, Field Services Manager, at 920-219-2286 if you have any questions about the operation of Mepaco equipment or if a training visit is necessary for new personnel.

Mepaco Dumper Equipment: New Options Improve Food Safety

Tue, 20 Sep 2016 18:56:00 GMT

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.

Food Product Bulk Dumper Equipment Customized for Extreme Sanitation Protocols

Tue, 12 Aug 2014 17:02:00 GMT

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.
