Vacuum Sausage Stuffer

Mepaco's Continuous Vacuum Stuffer removes entrapped air from both fine and coarse ground products. As a result, the 420V Vacuum Stuffer produces a firmer, denser product. Through consistency and uniformity; slicing yields are improved while color, temperature and texture are maintained.

  • Sanitation and Safety Checklist: Time for a Review? Posted 3 months ago
    An equipment safety and sanitation audit can provide direction for implementing improvement procedures and specifying equipment updates that mitigate risk and solve for safety and production goals.  Here’s an excerpt from our audit checklist: Are all parts of the equipment readily accessible for inspection, maintenance, sanitation? Is there any evidence of premature wear on parts? Does the equipment properly self-drain to assure food product, water or sanitizing fluids do not accumulate? Are all hollow areas removed where possible or permanently sealed to eliminate any harborage areas? During operation, does the equipment perform properly as not to contribute to unsanitary conditions? Is the equipment free of niches, pits, cracks, corrosion, recessed, open seams, gaps inside threads, bolt rivets, protruding ledges, rusting and dead ends? Are the enclosures and HMIs designed, constructed, and maintained to ensure food product, water or other liquids do not penetrate or accumulate on the enclosure or interface? Is there adequate space between ...

  • Proper Operational Procedures Improves Dumper Performance Posted 2 years ago
    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 ...

  • Polymer Bearings: Mepaco’s Customers Showing Promising Results Posted 4 years ago
    With the sophisticated demands in food processing and production, safety and quality, every component within food equipment is critical. Any machinery with moving parts has friction and ‘wear’ issues, and to accommodate most equipment uses a standard bearing. But in applications where the standard bearings compromise food contact areas, Mepaco offers the polymer bearing. Standard issue bearings are typically ball bearings, mounted in a painted cast iron housing. While the painted coatings are a sealant and deliver anti-corrosive benefits, rust and paint chips can still exist and find its way into the product path. Secondly, maintenance, disassembly, and replacement of bearings is very time consuming in a busy production setting. And lastly, if used above an open product path, grease may cause product contamination. For these reasons, steel ball bearings are best used in equipment and areas where they will not come in contact with food. In food processing environments, producers should consider polymer bearings to mitigate food safety risks. The polymer bearing has a moderate up front investment – more than steel bearings – but the Total Cost of Ownership is ...

What is the throughput of a vacuum stuffer?

It depends on the product and process. For example, a stuffer producing an emulsified luncheon meat product can produce up to 36,000 lbs. / hr.

What types of food manufacturing applications utilize a vacuum stuffer?

Meat, baking, pet food, prepared foods, dairy and confectionery processing industries.

How deep of a vacuum can you pull?

Mepaco's 420 Vacuum Stuffer is designed to pull and maintain full vacuum (29" HG). Vacuum can vary depending on barometric pressure and elevation.

Does the vacuum stuffer improve shelf life?

Yes, products have better color and there are no voids in cased product.

Is the vacuum adjustable?

It does not come standard, but adjustable vacuum is an option.

Do you have variable hydraulic options?

Different motors are available depending on the viscosity and density of the product.

How does the equipment determine level of product in the tub?

With a hi-low level probe.

Is the feed pressure adjustable?

Yes, the feed pressure is adjustable from 0 - 100%. Load sensing is automatic.

Can it be hooked up to an emulsifier or an inline grinder?

Yes, here is an image of a system.

Is a vacuum included?

Yes, Bush is standard and a Vane or Water Ring will be specified depending on the application.

Does this unit include a hydraulic pump?

Yes, the stuffer comes with a self contained hydraulic pump.

Is an electric model available?

Yes, electric models are often specified in continuously running applications.

Does the stuffer run batches or is it designed for continuous operation?

The stuffer can be set up for single batches or continuous operations.

Why is my probe not working?

When the probe is not working properly, you need to adjust sensitivity. Product moisture, consistency and density can affect the sensitivity of the probe.

Why is my pump not working at full capacity?

There are several possibilities why the pump may not be working correctly. Check for signs to see if the housing is worn. Also, check to see if the vanes are worn. The motor or hydraulic pump may also be worn. Check for physical wear on housings and vanes. Check the flow meter on hydraulic motor or the hydraulic pump may need to be serviced.

Why does my unit not maintain vacuum?

If vacuum is not holding, check for worn shafts, seals and gaskets. The gaskets may not have been installed properly. Check to see if the vacuum pump needs to be serviced.

What is the size of the tubing inlet?

Our standard size is 6" or 8" diameter.

Can a stuffer be filled?

Yes, but it would not be efficient for most applications.  Vacuum works with product being pulled through the inlet. For testing applications, a stuffer could be manually filled, but there would be a wait for the vacuum.

Should an emulsifier be placed before or after the stuffer?

We've seen both ways, after takes all the oxygen out of the meat and the texture is different. Seals must be maintained in the emulsifier otherwise eoleygen goes back in and the particle definition is different.

How do you check to see if all air voids are out of the product?

Conduct a saline solution test. The higher the salt solution, the less it floats.
