How Cobots Can Benefit Frozen Food Plants

How can cobots for frozen food plants help with case and tray handling?

Cobots for frozen food plants take the repetitive part of case and tray handling, the same placement motion repeated all shift, and leave the judgment work with people. A cobot is a collaborative robot arm built to work next to staff. It is coated in soft rubber and runs at slow speeds, so it can stop without injuring a person who touches it, according to a Packaging World special report on cobots placing top sheets on frozen food cases.

The practical benefit is that the arm takes the steps that wear people down, such as placing cap sheets, moving trays and stacking cases, while your team checks seals, labels and fill at the points where a person's eye matters most. Food manufacturers are looking at cobots and robots for four reasons: employee retention problems, higher throughput outcomes, safety concerns and a growing number of SKUs, according to Food Engineering.

The rest of this page covers the problem at a frozen food plant today, where the cobot works, how it fits with your crew, what drives the savings, what it cannot do, and how to start with a lease quoted after a free site assessment.

What problem does a frozen food plant face today?

A frozen food plant runs many of its packing and end-of-line steps by hand or with fixed equipment that still needs people to feed it. Cases and trays come off the line in a steady stream, and someone has to place, load, stack and move them. The work is repetitive and physically hard, which is why the trade press and safety researchers keep returning to it.

The workforce is large. According to IBISWorld, 96,550 people were employed in frozen food manufacturing in 2025, with an estimate of about 98,393 for 2026. IBISWorld also reports an average of 150.2 employees per business, though it does not state how many businesses that covers. A federal series counts the industry differently: according to FRED, the BLS employment series for NAICS 31141 shows 104.923 thousand in 2024 and 102.7 thousand in 2023.

Frozen product adds handling pressure. According to published research on severe injuries in the US food supply chain from Penn State, packaged food is often aggregated on palletizers before forklifts and pallet jacks move it. That puts the end-of-line steps in focus, and it is the reason to measure those steps on your own floor.

What are the main benefits of cobots at a frozen food plant?

The first benefit is consistent placement. A cobot repeats the same motion at the same pace late in the shift as it does early, so cap sheets and trays land where they should on case after case. A packaging vendor's published case describes a dual-cell setup with cobot cap-sheet placers serving four palletizing lines dedicated to a new case, with two more lines when needed. That is vendor-reported, so treat the performance as the vendor's claim and confirm it on your line.

The second benefit is cleaner product. The same vendor case says the cobot placers keep cases free from dust. Dust control matters in a food plant, so it is worth asking how the cell is enclosed and cleaned, and checking that claim on your own line.

The third benefit is physical relief. In a meat-case palletizing example in the same trade report, manual palletizing was described as repetitive and strenuous. A cobot with a vacuum gripper and a vision system fit where a caged robot would not, and its footprint is under 2 sq ft, according to the report, which is also vendor-reported.

How does a cobot work on the line day to day?

On a frozen food line, the cobot sits at a station beside the conveyor. Trays or cases arrive on the belt, the arm picks or places them according to a fixed program and sensor or vision cues, and finished cases move on down the line. Because the arm moves slowly enough to share the work zone with people, staff can work right beside it to clear a jam, swap a roll of cap sheets or pull a case for a check.

Scale-up follows the same logic. The vendor case mentioned above describes a plant that also ran 12 robotic palletizers for frozen food products, and it names tuning the robot base tolerance as the main challenge. That is a useful reminder that integration matters as much as the arm itself.

Integration is where most early effort goes. Expect a site survey, a mounting plan, tuning, a trial run on one line, and training for the people who will work beside the cell before it goes live.

Which areas of a frozen food plant does a cobot work in?

A cobot fits a set of stations rather than the whole building. The areas below are the ones where repetitive transfer happens and where a fixed arm can reach a known position without a cage. Treat the list as a starting point for the site assessment, not a fixed scope.

Cobots work best where the motion repeats and the product arrives at a known place. The zones below show six such areas on a typical frozen food packing floor, from the packing station to the staging lanes where pallets wait for forklifts.

How do cobots work alongside your existing staff?

A cobot does not replace the crew. It takes the repetitive transfer at one station, and your team moves to the work that needs judgment: line checks, seal and label inspection, product quality, changeovers and the fixes that come up on any shift. The model is a robot plus a smaller team, never a line with nobody on it.

People who run the line need to know what the cobot is doing and how to stop it. Training should cover starting and stopping the cell, clearing a stall, and reading its status indicators, and it should happen before go-live. A go-live support visit lets the crew see the cell run on their own product.

Staffing context matters. According to the US Bureau of Labor Statistics, about 371,600 people were employed as packaging and filling machine operators and tenders in May 2023. That is the pool many lines draw from, and the cobot's job is to free their time for the work only they can do.

What drives the savings, and what does it look like in hours?

The savings come from hours. Every hour a person spends lifting trays or placing cap sheets by hand is an hour that can move to line checks, quality work or a second station. This page does not include a sourced hours range, because the figures verified here describe the industry, not your line. We cannot promise a number, since it depends on line speed, product mix, shift pattern and how much of the job the cell takes over.

What we can do is measure before you commit. During a free site assessment we map the station, time the repetitive steps on your line, and count the hours per shift the cobot can take. Those hours are the basis of the savings picture, and you can check every one of them against your own schedule.

The lease sits on top of that picture. A cobot is leased through financing, and the fixed robot lease payment comes in the quote after the site assessment. That lets you weigh the hours freed against the payment using your own numbers rather than a generic estimate.

What can a cobot not do at a frozen food plant?

A cobot cannot judge quality, and it should not be asked to. Line checks, seal and label inspection, and decisions about a bad case belong to your people. It also needs a person to run changeovers, sanitation and maintenance, and it does not replace those crews.

The arm is also not the fastest machine on the floor. Cobots run at slow speeds so they can work safely near people, so a line that needs high cycle rates may need a faster fixed machine at that step, with the cobot covering the handling around it.

Setup is another limit. The vendor case names tuning the robot base tolerance as its main challenge, so a cell needs careful mounting and calibration before it runs well. Plan for that in the schedule rather than assuming it will be quick.

How do you get started with a cobot lease?

Start with one station, not the whole plant. Pick the handling step that repeats most and that your team complains about most, then let the site assessment confirm it. A single cell on one line is the lowest-risk way to see how the cobot fits your floor and your crew.

Our process is straightforward. We pick the right cobot for the site, lease it through financing, deploy and integrate it, train your staff, and service it nationwide. The site assessment is free, and the lease quote comes after it, so the fixed robot lease payment is set against your line rather than guessed from a brochure.

Ask for three things in writing: the hours the assessment measured, the quote, and the service plan. Ask who services the cell after go-live and how fast a technician can reach your site, since a stopped cell means a stopped station.
