The Dried Fruit Market: Between Snacking Trends and Technical Challenges

The dried and dehydrated fruit sector is experiencing an unprecedented expansion phase in the global food landscape.

According to mordorintelligence, the compound annual growth rate (CAGR) of this sector is projected at 5.35% for the 2026–2031 period.

The consumption of these foods has become a cornerstone of the modern diet.

Driven by the search for healthy, high-protein, and natural alternatives for daily breaks, consumer habits have changed radically.

With the development of new food trends, packaging styles are also evolving.

Today, demand is primarily focused on small single-dose formats and packaging designed for on-the-go consumption, at the office or after sports activities.

For industrial producers and packers, this trend translates into technological challenges that demand state-of-the-art machinery:

• Preserving Freshness and Extending Shelf-Life: Dried fruit is prone to oxidation when exposed to oxygen or light. Modern packaging requires impeccable hermetic sealing and often the use of modified atmosphere packaging (MAP). This ensures extended shelf life and preserves organoleptic properties.
• Product Integrity and Delicacy: Consumer perceived quality is closely tied to visual appearance. Therefore, an efficient packaging line must handle the product gently, preserving its original appearance.
• Dosing Precision: This is perhaps the most critical point for business profitability. Even a minimal error of a few tenths of a gram per package can generate substantial financial losses on an industrial scale. If a line produces thousands of pouches per hour, overfilling becomes an unsustainable cost.

To meet these needs with maximum efficiency, MF TECNO positions itself as a single point of contact capable of delivering complete turnkey packaging systems.

From primary dosing into pouches to secondary cartoning and final palletizing.

Primary Packaging: The MF 50 Speedy and MF 52 Speedy Vertical Packaging Machines

MF TECNO offers two benchmark models specifically designed to ensure high precision, flexibility, and production rates, adapting to various production scales.

Both models operate with continuous motion, minimizing mechanical stress on packaging materials and enabling the use of thinner or more sustainable films without risk of tearing.

MF 50 Speedy: Compactness and Flexibility for Small to Medium Productions

The vertical form-fill-seal machine MF 50 Speedy represents the ideal solution for companies seeking maximum versatility within a compact footprint.

Key features tailored to dried fruit packaging include:

• Reduced Footprint: Its extremely compact structure easily integrates into existing production facilities or lines with severe space constraints.
• Rapid Format Changes: The MF 50 Speedy allows quick transitions between formats (e.g., from 30 g to 250 g), significantly reducing downtime and maximizing operational availability.
• Hygiene and Sanitation: Every component in contact with the product is designed to prevent dust or residue accumulation. Built with premium materials and stainless-steel options, it perfectly meets the hygienic standards required by the food industry.

MF 52 Speedy: Ultra-High-Speed Continuous Technology

Where speed is the decisive factor, MF TECNO offers the MF 52 Speedy.

A model capable of reaching up to 4,800 packages/hour for formats up to 5 kg. The MF 52 stands out for:

• Integration with Multihead Weighers: The MF 52 Speedy pairs seamlessly with high-precision electronic multihead weighers, guaranteeing maximum filling accuracy and flawless product drop during pouch formation.
• Sealing Versatility: It handles various film types with extreme precision (laminates, recyclable mono-polymers, or compostable materials). It produces Pillow Bags, Block-Bottom bags, Eurohole pouches (essential for vertical display on supermarket shelves), and Doypack formats.

Secondary Packaging: Protection and Aesthetics with MF TECNO Cartoners

When operating at high speeds on small formats, managing secondary packaging is crucial.

Often, the primary line is so fast that manual cartoning becomes an insurmountable bottleneck.

For this reason, MF TECNO develops automated cartoning solutions that seamlessly integrate the flow of pouches coming from vertical packaging lines.

Wrap Around Cartoner

The Wrap Around Cartoner is the ideal choice for businesses looking for compact, rigid, and aesthetically flawless secondary packaging at production rates of up to 20 cases/minute.

• Forming Around the Product: Unlike pre-glued boxes, here a flat cardboard blank is wrapped and glued directly around the grouped pouches. This ensures a custom fit, eliminating internal product movement during transport and reducing damage risks.

• Material Optimization: This system significantly reduces cardboard usage compared to traditional methods. Furthermore, it enables the creation of Ready-to-Shelf display boxes with pre-cut perforations for immediate placement on retail shelves, a feature increasingly requested by Large Scale Retailers.

American Box Cartoner (Top Loading)

For productions demanding maximum robustness and flexible configurations, the American Box Cartoner ensures high performance and complete protection for international shipping or complex logistics.
 

• Top Loading Mechanism: Dried fruit pouches are picked, grouped, and inserted into pre-formed regular slotted containers (RSC) using advanced Pick & Place systems, utilizing cartesian robots or articulated arms depending on layout complexity.
• Pattern Flexibility: This system handles diverse filling configurations (flat, upright, or alternating products), adapting easily to different case formats while providing high mechanical protection for long-term storage and transit.

End-of-Line and Logistics: The MF PCA SMART Cartesian Palletizer

The final phase, often overlooked, is palletizing.

In modern food packaging plants, space is a valuable and limited resource. To address this, MF TECNO designed the MF PCA SMART Palletizer.

The main advantages of this model are:

• Compact "Plug & Play" Structure: Featuring an extremely footprint-conscious design, the MF PCA SMART can easily fit into tight areas where traditional palletizers cannot. Its modular design allows minimal installation and startup times.
• Cartesian Precision and Reliability: The 4-axis system ensures fast and millimeter-accurate positioning of boxes and bundles onto pallets. This precision is key to guaranteeing load stability during road transport.
• Intuitive HMI Management: An expert programmer is not required. The touchscreen user interface allows operators to set up and modify palletizing patterns quickly and easily, making the facility independent when managing new formats.
• Safety and Ergonomics: Automating palletizing is not just about speed; it eliminates heavy, repetitive manual labor for operators, drastically reducing injury risks and ensuring continuous multi-shift operations.
