Machines and complete lines for vegetable processing
Stumaco started out in frozen vegetables, and that is still where our deepest know-how lies. We design, build and install lines for peas, beans, spinach and other vegetables: from quality sorting ahead of the freezing tunnel to breaking, mixing, conveying and packaging. As integrator, we bring all machines together, including those from external suppliers. You work with one point of contact, from the first design to service after handover.

We integrate vegetable lines from freezing tunnel to packaging, even in the busiest weeks of the season.
Trusted by leading food producers
Leading producers of frozen vegetables across Europe have worked with Stumaco for years.

One line, fully aligned
Frozen vegetables that clump together after freezing, a blend ratio that is off, or a line that stops in the middle of the season: it costs you quality and yield straight away. Stumaco knows these processes from the inside.
- Before the freezing tunnel: quality sorting, inspection and even distribution across the freezing tunnel
- After the freezing tunnel: breaking, sorting, buffering, mixing and dosing to packaging
- Production lines: complete lines for products such as spinach portions and vegetable mixes
- Hygiene: open, easy-to-clean stainless steel constructions, with ViwateQ surface treatment so product residue and dirt adhere less

From intake to packing, every step from a single partner
We supply individual machines and complete lines, including conveying, buffering, platforms and installation. These are the process steps in which we support you.
Intake & cleaning
Intake hoppers, tote dumpers, destoning with destoning belts and cyclone destoners, and washing with drum washers, paddle washers and flotation washers.
Cutting & preparation
Decoring machines, pre-cutters for salad, cauliflower cutters, destemming shakers for beans and slicers for mushrooms.
Sorting & inspection
Datura removers, nightshade removers, insect drums, roller graders for onions and beetroot, sorting shakers and inspection belts.
Blanching & cooling
Belt steamers, belt blanchers and blanchers with dipping and cooling augers for even heat treatment.
Dewatering & drying
Dewatering shakers, tension screen shakers, dewatering belts and flow dryers for leafy vegetables and salad.
Freezing & finishing
Freezing tunnels and spiral freezers, followed by breaker rolls, cluster busters and glazing drums for a free-flowing product that doses well.
Mixing, weighing & filling
The Mixline for frozen vegetables, batch weighers, multihead feed shakers, weigh belts, Eqlipse dosing systems and box filling systems.
Water & residual streams
Drum filters, sieve bends, sand traps, flotation and water treatment to reuse process water and process residual streams.
Machines for every step in your vegetable line
Wondering how much more there is to gain from your vegetable line?
Discuss capacity, product quality or an extension with one of our project managers. Together we look at which modification delivers the most and how to fit it in before the next season.

Focused on the lowest TCO for your vegetable line
Vegetable processors deal with seasonal peaks, a variable raw material and high water and energy consumption. That is why we do not look at the price of a single machine, but at the costs and yield of your entire line over its full service life.
Machines delivered
Our machines are in operation at food processors around the world, in both fresh and frozen production.
Countries
Installation and service wherever your plant is located, including fast delivery of parts.
Specialists
Engineers, fitters and service technicians with many years of expertise in washing, blanching and freezing.
Experience per company
An average of 30 years of machine building per company, refined in practice at food processors.
Machine types
From intake hopper to freezing tunnel: virtually every step in your vegetable line is covered in-house.
End products
Fresh: salad, leafy vegetables, cabbage, carrots, onions and leeks. Frozen: from peas, beans and spinach to Brussels sprouts, mushrooms and beetroot.
Point of contact
One project team for the design, construction, installation and servicing of your complete line.

Seven specialists, one team
Stumaco is the integrator within the Sticomax Group. For your vegetable line, we combine our own machines with those of the other specialists in the group and of external suppliers, such as optical sorters and freezing tunnels. You have one project team and one point of contact for your complete line.

Experience with leading food producers
Industry-leading service & maintenance
During the season, a vegetable line often runs day and night, and the raw material cannot wait. That is why we plan installation and maintenance around your season, including weekends or nights when needed. After handover we stay involved, so your line keeps running.
- Installation and commissioning on site
- Installation outside the season or outside production hours
- Preventive maintenance and inspections, preferably before the season
- Fast delivery of spare parts, also across borders
