How Automation Is Changing Fruit and Vegetable Processing Plants in 2026

For many fruit and vegetable processors, increasing production used to mean a simple solution: add more workers.

That approach is becoming harder to maintain.

As production volumes grow, processors have to think about more than how fast one machine can work. They also need to consider how products move between washing, sorting, cutting, grading and other processing steps.

This is where automation is making a practical difference.

A modern fruit and vegetable processing line does not necessarily mean replacing every worker with a machine. In many factories, automation simply means connecting the right equipment so that products can move continuously from one process to the next, with fewer stops and less manual handling.

For processors planning a new plant or expanding an existing production line in 2026, this change is becoming increasingly important.

Automation in food processing is often discussed as a way to save labor, but that is only part of the reason.

The bigger advantage is better control of the entire processing flow.

Consider a vegetable factory where washing, inspection, cutting and grading are handled separately. Even if every machine works efficiently on its own, workers may still need to collect the product, move containers, feed the next machine and adjust production whenever one step becomes slower than another.

As production increases, these small interruptions can become bottlenecks.

Connecting equipment into a continuous processing line can help address several common problems:

• Reduce repeated manual loading and unloading
• Maintain a more consistent production flow
• Reduce unnecessary product handling
• Make production capacity easier to plan
• Improve consistency between batches
• Make future capacity expansion easier

This is why automation does not always begin with buying the fastest machine. It often begins with looking at how the entire process works together.

There is no single configuration that works for every fruit or vegetable.

A processing line for tomatoes can be very different from one designed for potatoes, leafy vegetables, onions or garlic.

However, a typical industrial fruit and vegetable processing line may include:

Feeding → Sorting → Washing → Peeling → Cutting → Grading → Dewatering or Drying → Packing

Some projects require only three or four of these steps. Others may require additional equipment depending on the final product.

For example:

Fresh vegetables may require washing, inspection, cutting and dewatering.

Root vegetables may require washing and peeling before cutting.

Fresh fruits sold by size may require washing, surface drying and grading without any cutting.

Vegetables intended for dehydration may continue from washing and cutting directly into a drying system.

This modular approach is one of the most important changes in modern food processing equipment: the production line can be designed around the product and process instead of forcing the product into a fixed machine configuration.

Not every step needs the same level of automation.

In practice, automation creates the most value where products need to be moved repeatedly or where a process must remain consistent for long periods.

1. Washing and Cleaning

Washing is often one of the first stages to be integrated into a continuous line.

Depending on the raw material, industrial washing equipment can use bubble washing, water circulation, spraying, brushing or other cleaning methods.

Once washing is connected with upstream sorting and downstream processing equipment, operators no longer need to repeatedly collect and reload the product.

2. Sorting and Inspection

Automation does not mean manual inspection has to disappear.

For many products, especially fruits and vegetables with irregular shapes or surface defects, manual inspection remains useful.

The difference is that workers can inspect products while they move through the line, rather than handling baskets or containers between separate machines.

This combination of manual inspection and automated conveying is often a practical solution for processors that want higher efficiency without overcomplicating the production line.

3. Cutting and Size Reduction

Cutting is another area where continuous feeding can make a significant difference.

Depending on the product, processors may need slicing, dicing, shredding, strip cutting, top-and-tail cutting or other forms of size reduction.

The important question is not simply:

“How fast can the cutting machine run?”

It is:

“Can the upstream equipment supply product at the right speed, and can the next process handle the output?”

A 1,000 kg/h cutter provides little benefit if the washing section can only supply 500 kg/h.

For this reason, line capacity should be considered as a complete system rather than as the maximum capacity of an individual machine.

4. Grading and Sorting by Size

For processors selling fresh produce, grading can be just as important as washing.

Tomatoes, citrus fruits, potatoes and many other products may need to be separated into different sizes before packing or further processing.

Connecting the grading machine directly with washing and inspection equipment allows products to move through these steps without intermediate handling.

The result is a simpler workflow:

Inspect → Wash → Grade → Collect

rather than processing each step independently.

A tomato processing line is a good example of how simple automation can improve the overall workflow without making the system unnecessarily complicated.

In a typical configuration, tomatoes first pass through an inspection area where operators remove unsuitable products.

They then enter the washing section automatically.

After washing, the tomatoes are transferred directly to the grading machine, where they are separated into different size categories.

The process becomes:

Manual Inspection → Washing → Automatic Transfer → Size Grading → Collection

There is no need for workers to carry tomatoes from the washing machine to the grader between these processing stages.

A fully automatic line is not automatically the best choice.

This is an important point when planning a new food processing project.

For a smaller processor handling several products in relatively low volumes, a semi-automatic line may offer more flexibility and require a lower initial investment.

For a factory processing large volumes of the same product every day, reducing manual transfer and connecting more processing stages may provide much greater value.

The right automation level depends on several factors:

The goal should not be to automate as many processes as possible.

The goal should be to create a line that matches the actual production requirement.

Before selecting individual machines, it helps to define the complete process first.

Start with five basic questions:

What raw material will you process?

Tomatoes, potatoes, onions, leafy vegetables and fruits behave differently during washing, conveying and cutting.

What is the final product?

Whole washed produce requires a very different line from sliced vegetables or dehydrated products.

What capacity do you need?

Capacity should be defined for the complete line, not just one machine.

Which steps do you need?

Some factories only need washing and grading. Others need a complete process from sorting to drying.

How much space is available?

Equipment selection is only one part of line design. Machine layout, operator access, cleaning space and product flow should also be considered.

Once these points are clear, it becomes much easier to determine where automation is useful and where manual operation still makes sense.

For food processors, the value of automation is not simply having more machines.

It is making sure those machines work together.

This is also how IKE approaches food processing line projects.

Instead of starting with a fixed equipment package, the line can be configured according to the customer's raw material, required processing steps, production capacity and available factory space.

Depending on the project, IKE food processing equipment can cover different stages such as:

Sorting → Washing → Peeling → Cutting → Grading → Dewatering → Drying

Individual machines can also be connected to create a continuous processing system, reducing unnecessary transfer between stages.

For example, a processor may start with a washing and grading line today and add cutting, dewatering or drying equipment as production requirements develop.

A common mistake when buying food processing equipment is starting with a machine list instead of starting with the product.

The same processing line cannot simply be copied from tomatoes to potatoes, onions or leafy vegetables.

The product determines the process.

A tomato line may focus on gentle washing and size grading.

A potato line may require brushing, peeling and cutting.

An onion line may require top-and-tail cutting and peeling.

A leafy vegetable line may place more emphasis on gentle washing and dewatering.

And a product intended for dehydration requires another important step: controlled drying after pre-processing.

This is why customized line design becomes more important as processors move from individual machines toward continuous production.

The future of food processing is unlikely to be a factory without people.

Instead, the more practical direction is a factory where workers spend less time carrying, loading and repeating simple processing tasks, while machines handle more of the continuous production flow.

For many fruit and vegetable processors, the first step does not need to be a completely automated factory.

It may simply be connecting two machines that currently require manual transfer.

Then three.

Then an entire processing line.

That gradual approach makes automation easier to adapt to real production needs and allows equipment to grow with the business.

If you are planning a new fruit or vegetable processing project, start with the product rather than the machine.

Define:

What are you processing?
What final product do you want?
How much do you need to process per hour or per day?
Which processing steps are required?

With this information, the equipment configuration becomes much clearer.

IKE provides individual food processing machines and customized processing line solutions for washing, sorting, peeling, cutting, grading, dewatering and drying applications.

Whether the project requires a single machine or a connected processing line, the equipment can be configured around the actual production process.
