Why invest in blueberry packing lines from Milbor PMC?

Blueberry lines tailored to your needs

We don't work from templates. We create personalized blueberry packing lines tailored to the specific packhouse infrastructure, the investor's needs, and their development plans.

Proprietary machines and systems

We design and manufacture many of the machines in our offer. Thus, the flexibility also allows us to integrate existing line elements with new equipment.

Weighing precision

Our lines use the G3 Evolution weigher the fastest and most accurate linear weigher. With the G3, you will reduce costly overwieghing to a minimum and increase your margins.

Precise sorting

The line can be equipped with the MXM BN.2 optical sorter, enabling precise and fast sorting of fruit by color, softness, and size. With it, only fruit meeting retail chain requirements will end up in punnets.

Efficient packaging sealing and labelling

Packaging containing fruit must be sealed and labelled. We offer high-capacity labellers and traysealers that ensure continuity of the packing process.

Care for fruit quality

Minimal drops and silicone paddings ensure that blueberries retain their bloom and firmness during automated packing.

For companies selling blueberries to retail chains in ready-made packaging of specific weights.

The price depends on the project and the components that make up the line. Costs can vary significantly depending on the investor's needs and goals. In addition to the machines, the price is also affected by installation and equipment integration. For a precise determination of the costs associated with a blueberry punnet packing line, we invite you to a no-obligation consultation with our sales representative.

Our clients' experience confirms that investing in a blueberry line becomes profitable at production volumes exceeding 200 tons of fruit per season. At this level of production, the investment can pay for itself in as little as 2–3 years.

Our client's story

Berritum is a Polish company specialising in packing and selling fruit to foreign retail chains. The company sources blueberries from various origins, which results in variation in fruit quality.

Berritum's foreign buyers expect uncompromising fruit quality and delivery consistency. Given the variety of fruit purchased in bulk from growers, Berritum's business model requires very precise sorting. Soft, unripe, or undersized blueberries in packaging supplied by Berritum could result in complaints and contract termination. The second challenge is weighing accuracy. Overweighing by just a few grams when packing blueberries into small 125–500 g containers can cost the company tens of thousands of euros per season.

Berritum has been our client for many years. Recently, the client decided to replace their old blueberry sorter with our MXM BN.2 optical sorter. The device enables simultaneous assessment of three fruit parameters, does not damage blueberries, and takes up little space in the packhouse. The MXM BN.2 provides very precise blueberry sorting and is gentle on the product. The current line consists of the MXM BN.2 sorter, an inspection table, a G2 weigher, a REV5 traysealer, a labeller, and conveyors connecting the individual machines.

The line delivered to Berritum confirms that well-matched technology translates into strong results in fruit packing. The G2 weigher reduces overweighing to 1 blueberry per punnet, meaning our client doesn't give away fruit for free. The REV5 heat sealer closes packaging with a heat-shrink film layer, which is becoming the standard required by large-format retailers. The implementation of the MXM BN.2 sorter resulted in a drop in complaints to below 1%. Optimal integration of the individual line elements gave Berritum better process control, a high level of consistency, and reduced downtime.

A diagram of the line

Here comes an example layout of blueberry punnet line:

Infeed conveyor

The infeed conveyor is the first element of the line and the initial stage of the automated packing process. It features a wide fruit transport belt and adjustable height, allowing it to be matched to the level of the sorter.

Rotary blower

It is the initial stage of sorting and is essential for machine-harvested fruit. A powerful airstream removes leaves, stems, and other debris collected by the harvester in the field.

MXM BN.2 blueberry sorter

This optical sorter is equipped with two 2K cameras, enabling precise assessment of each fruit in terms of size, ripeness, and softness. It achieves a capacity of up to 3 tons per hour, while its compact design means it takes up little space in the packhouse.

Inspection table

A conveyor designed for manual sorting. Depending on the client’s needs, it can be used in the line as a complement following the mechanical sorter.

Z-type conveyor

A conveyor that carries fruit up to the weigher. It can be positioned perpendicular to the inspection table, which significantly simplifies line layout in the packhouse. It can operate at speeds of up to 3 tons/h while remaining very gentle on the fruit.

G3 Evolution weigher

A blueberry packing machine combining high packing accuracy (down to 1 fruit per punnet) with high throughput. The G3 is available in various weight configurations and can pack fruit into different types of packaging.

Adjustable transport conveyor

Transfers punnets filled with fruit to the next stage of the packing process. It allows easy height adjustment, effectively connecting the weigher index conveyor with the remaining elements of the line.

Transport conveyor

We offer various shapes and sizes of packaging transport conveyors, allowing the line to fit within the packhouse space. Additionally, the conveyors can be equipped with a stand for manually applying plastic lids.

Traysealer REV5

An intelligent traysealer packaging sealer closes packaging with heat-shrink film. It can work with various punnet formats, and the technologies used minimise the risk of downtime.

Labeller

A device for labelling sealed packaging. The labeller is available in single- or double-head configurations.

Three-tier collection table

The final element of the blueberry line. At the collection table, fruit packaging is transferred into larger containers for dispatch to points of sale.
