Mepaco - 90 Years in the Making

Mon, 28 Feb 2022 18:37:21 GMT

The Mepaco® brand has been around for a long time. The company began in 1932 and operated out of Oakland, California. The name Mepaco® stands for Meat Packers Equipment Company. For the first 40 years, Mepaco® was a significant equipment supplier to deli meat, sausage, and smoked meat processors. Mepaco® offered loaf molds and slicers, cooking and cooling racks, smokers, brine tanks, manual cutting tables and workstations. Mepaco® also offered Mixers. One of their earlier Mixers was called a Buffalo Mixer and was engineered to automate the sausage making process.

Early catalogs highlight that the mixer was also offered as a customized solution to include a heat jacket. The company would develop more equipment products around mixing and cooking in the years that followed.

Apache purchased the Mepaco® brand in 1993. The assets were moved to Beaver Dam, Wisconsin. It was an excellent fit for Apache’s fabrication specialists because of our expertise in manufacturing stainless steel original equipment for processing industries.

With a background in heavy industrial stainless equipment manufacturing and ASME expertise, Apache influenced the equipment designs, especially processing equipment like mixers, cookers, and blenders. The equipment transformed into strengthened frames and components. Heat transfer technology was engineered to the level of expectations within Apache’s critical industry processors. Under Apache’s ownership, Mepaco® processing equipment began serving red meat, dairy, poultry, baking and processed foods industries.

Today’s Mixers, Cookers and Blenders designed by Mepaco® are highly engineered and highly controlled systems for large-scale batch operations. It is not uncommon for batch sizes to reach 8000 lbs. in Mepaco®’s Mixers and Blenders. Mepaco®’s equipment solutions are seen in more industries including pet food, plant-based products, and prepared foods.

The ThermaBlend® Cooker, debuted in 2006, is a trademarked brand. A highly efficient cooking/blending solution, the ThermaBlend® has a massive heat transfer benefit with highly efficient agitators and a patented scraper system that proves fast processing times. True to Mepaco®’s value to processors, the ThermaBlend® Cooker is engineered for specific customer goals, and is capable of cooking, searing, caramelizing, chilling, sautéing, and blending.

Celebrating 90 years in 2022, Mepaco® is known for its formulating and thermal processing solutions. Our value to processors is our ability to modify and adapt designs, functionality, and controls technology to solve processing problems. The need for this level of customization has grown into engineering entire processing room systems. Mepaco® has designed coordinated systems integrated with high-performance equipment for small and growing processing companies as well as Fortune 500 food manufacturing corporations.

The Mepaco® team, works every day to provide:

Ruggedly engineered, reliable equipment
Maximum yield performance
Optimal designs for maintenance and operation
Vigilant compliance for personnel and food safety

What does the future hold? Through interviews, conversations, and surveys, we are listening to customers and learning about what they need from our company. We are looking at new equipment products and making improvements in service support and resources in 2022, a direct result of recent customer survey feedback. To our customers, thank you for your business and the valuable feedback that helps us strengthen our partnerships.

Case Story: What Can Happen When an Agitator Problem is Ignored?

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.

Why Agitator Solutions are Important to Quality and Throughput in Cooking Operations

Thu, 18 Feb 2021 18:57:26 GMT

The type and viscosity of food product, thermal processing technology, desired texture, and cooking/processing cycle times are considered when specifying the agitator solution. Primary consideration for mixing or blending agitator solution begins with the ability for the food product to self-level. Agitator configurations also include scrapers with indirect cooking applications.

In some applications, the agitator itself may not significantly affect throughput improvement, but the overall solution does. The driving forces for throughput in batch processing is cycle times, loading, and discharging.

However, the wrong agitator solution will not mix or blend the product well. Solids need to be homogeneous and remain intact during processing operations. Further, the product must remain in a mixed state throughout the process and discharge operations.

During project discussions, Mepaco’s application team defines mixing as adding ingredients for the correct mix and consistency, while blending provides a change of the food product's properties.

The thermal processing solution is customized to the specific application. The PLC is programmed to include agitator speeds, pauses, and direction changes for the desired results. Further, the Mixer or Blender equipment will be sized for the batch volume required along with options (vacuum, cooling, searing, caramelizing) to meet the batch cycle times, quality and throughput goals for the processing solution.

Ask the Experts - at Process Expo - The Lab Mixer

Wed, 09 Oct 2019 00:26:45 GMT

Tom Hoffmann, Director of Mepaco Sales, gives a tour of a lab mixer at Process Expo. The lab mixer was engineered and manufactured for UW-Madison's new meat science lab. The equipment is being donated for their new facility and educational center opening 2020.

This video is part of a series called "Ask the Experts" to highlight the equipment at the Process Expo.
