Seal of approval: how sealing machines expand food production margins

Supplier: MPI Australia
15 September, 2015

As food producers look to reduce product costs and increase their margins, the total cost of production equipment ownership becomes more vital.

If you do the math it's easy to see how you can achieve higher profits through decreased energy usage and increased efficiency; both being major steps in reducing your overall costs.

How can sealing machines achieve this?

New and innovative machines are being developed which are faster, and more energy efficient, effectively streamlining your processes.

As a food producer, you are wanting maximum output within an acceptable timeframe, so it's important to find a sealing machine that can pack and seal efficiently.

There are machines out there with single lane trays that are capable of up to 150 packs per minute; these machines often include features such as interpolated multi axis robotic motion, which allows for continuous flow of trays through the machine from infeed to outfeed, eliminating any need for pauses or buffering.

If you seek out an electric machine that operates without the use of compressed air you can also save yourself a huge chunk of your operating costs; conventional pneumatically operated tray sealers are often more costly to run, with their seal force inferior to that of an electric machine.

Some electric sealing machines are said to increase the seal by up to 300 per cent, in comparison to pneumatic tray sealers.

What are the major advantages of electric sealing machine?

One of the clearest advantages of an electric sealing machine is lower costs and increased efficiency; there is often less downtime with these machines. Some have even been specifically designed to trigger alarms when there's potential for a pack to get jammed, and for the pack to be removed easily from the feeder without having to restart the entire cycle and clear all packs from the area.

Many other user benefits have been added in updated designs, including smoother profiles of the punnet transfer into the machine, allowing for lighter or more easily displaced products such as small berries to be transferred without spilling at high speed.

For factories where security of machine settings and parameters can be an issue, modern sealing machines can be equipped with RFID fobs that stop operators from accessing certain permission levels within the machine's screen.
