Powder Technic / Powdea Automated Ingredient Dosing Systems, Silos and Spare Parts

System architecture of Powder Technic / Powdea automated ingredient dosing lines

Founded in 1989 by Jukka Kousa in Kotka, Finland, Powder Technic Ltd (operating under the official corporate name Powdea Technologies Oy, business ID FI0750334-8, since January 2022 while retaining Powder Technic as its subsidiary brand) engineers and manufactures turnkey bulk handling and recipe-controlled ingredient dosing systems.

Rather than assembling third-party subsystems, the company developed proprietary designs for every critical stage: silo filters, Fluidiser discharge cones, patented Cyclone Filters, Vacumatic pneumatic conveyors, Powdermatic micro-dosers, Fluidmatic liquid stations, Watermatic water mixers and SQL-based PLC controls.

Modular design allows bakeries, food plants and animal feed mills to automate step by step according to hourly batch demand.

Artisan and in-store bakeries producing 1-6 batches per hour utilize the semi-automatic Powdermatic M60 workstation, the Powdermatic 100-A inline unit, or the Plug&Dose Powdermatic Lite S and Lite M box dosers (100 l or 200 l hoppers, +/- 10 g typical accuracy, dosing roughly 1 collector box per minute).

Medium-sized plants producing 6-12 batches per hour deploy the Powdermatic 200-I (200-500 l tanks in row, ring or L-shaped layouts) or the combined Powdermatic 200 IB (200 l micro-ingredient hoppers paired with 350 l big bag hoppers), while high-output industrial bakeries running 20-40 batches per hour use the patented Powdermatic UF ultrafast system.

Outdoor GRP and indoor modular silos (mild steel, stainless steel, aluminium) with Fluidiser cones

Bulk storage solutions from Powder Technic (Powdea) cover outdoor fiberglass reinforced polyester (GRP) silos dimensioned from 10 to 100 m3 with FDA food-contact approval, corrosion resistance and protective lower skirts.

For indoor raw material rooms, the company manufactures painted mild steel silos (5-60 m3), hygienic stainless steel silos (5-36 m3), aluminium silos (5-30 m3 as well as 80 m3 industrial flour silos) and breathable Trevira polyester fabric silos suited for low ceiling heights.

Indoor steel silos are also available in stackable modular blocks for tight retrofit installations.

To eliminate bridging, rat-holing and moisture condensation across cohesive and free-flowing powders, silos and hoppers incorporate the proprietary Powder Technic Fluidiser auxiliary discharge bottom supplied with dried compressed air.

The special fluidisation fabric passed migration testing by SGS and carries official Food Safe status.

Silos are mounted on load-cell weighing supports for accurate inventory tracking and fitted with automatic post-fill filter cleaning, ATEX pressure relief valves, safety rails and overfill sirens with filter-service indicator lights.

Anti-Dust scale hoppers, FIBC big bag dischargers and Loss-in-Weight Smart continuous feeders

Above dough mixers, movable bowls, dry blenders and extruders, Anti-Dust scale hoppers provide high-precision batch weighing with minimal airborne dust.

Each Anti-Dust hopper integrates a patented Cyclone Filter that extends filter cartridge service life up to 10 years depending on duty (compared to 12 months for standard bag filters) and reduces dust emissions by 32% toward near-HEPA filtration levels.

During scale discharge, a pneumatic cylinder-driven dust hood lowers onto the mixer bowl while the cone geometry and Fluidiser pad ensure complete, residue-free emptying under ATEX ignition risk compliance.

For minor and bulk ingredients delivered in flexible intermediate bulk containers (FIBCs), Anti-Dust big bag discharge stations combine an approved hoist frame (electric or chain lift) with a safety clamping ring and dustproof access hatch for opening valve-bottom or closed-bottom bags without dust escape.

Where continuous gravimetric feeding is required, stainless steel Loss-in-Weight Smart dosers (50-300 l hopper volume, 5-1000 kg/h capacity) maintain +/-0.5% dosing accuracy (0.25-1.5% depending on powder rheology), locking the auger speed during refill and outputting real-time trend curves via fieldbus.

Vacumatic pneumatic conveying, Easy Clean screw conveyors and CS/EX centrifugal sifters

Dry ingredients are transferred from silos, big bag stations and Powdermatic units to receiving scales via Vacumatic vacuum conveyors, positive-pressure pneumatic lines or screw conveyors.

High-capacity pneumatic lines equipped with patented Cyclone Filters and separation cyclones achieve throughput rates of 6,000 to 10,000 kg/h (up to 10 t/h) and span conveying distances up to 100 m with terminal dosing accuracy around 200 g, supported by smart-conveyor diagnostics.

For conveying distances below 10 m and mobile wheel-mounted feeders, mild steel and stainless steel screw conveyors (0-90 degree incline) and tool-free Easy Clean food-grade augers provide economical transfer.

Powder conditioning equipment protects downstream mixers from foreign bodies and agglomerates. Clump breakers (1-15 t/h capacity) with interchangeable blade thicknesses mount directly beneath IBC dischargers, while inline Pneumascreens filter pressurized transfer lines.

Centrifugal sifters of the CS710/CS910 series and ATEX-rated EX710, EX910 and EX1100 models (internal zone ATEX 20/21, external zone ATEX 22, capacity 1-15 t/h) use durable perforated steel plate screen drums (0.15-10 mm apertures) instead of fragile nylon mesh, ejecting oversize particles into a waste bag and providing hinged inspection and end hatches for rapid grade changes.

Fluidmatic liquid dosing stations, Watermatic caloric water mixers and RB250 dry mixing lines

Liquid ingredients such as liquid yeast, molasses, malt extract, margarine, vegetable and canola oil, and sorbitol are metered gravimetrically by Fluidmatic dosing units.

A Fluidmatic station comprises IBC fluid containers or day tanks set on load-cell scale sensors within a compact stainless steel frame, paired with an integrated dosing pump and local-language operator panel.

For container filling lines, semi-automatic and conveyor-fed stations use washable stainless steel floor scales and automatic drip-lock filling lances.

Process water is metered by recipe-connected Watermatic and Watermatic Lite units, which dose water at the programmed temperature with 1 decilitre (0.1 l) accuracy using a caloric dosing algorithm; full turnkey bakery systems deliver up to 16 batches of 300 l per hour combining 26 dry ingredients and 6 fluids.

For dry premix and mineral powder plants, complete mixing and bagging lines integrate the Ribbon Blender RB250 dry mixer, Easy Clean transfer augers, the Fillermatic auger filler, SackFiller small-bag packagers and the DEU850 automatic dust extraction unit serving 1 to 5 extraction points.

Siemens S7 PLC automation, Table Scale with MiniERP, Dose-Track IoT and spare parts selection

Control architectures from Powder Technic (Powdea) are built on Siemens S7 and Mitsubishi PLCs with intuitive touch interfaces. Single-ingredient batch controllers feature a 7-inch touchscreen with large icons, automatic taring and manual actuator overrides.

Manual micro-ingredient weighing stations use the Powder Technic Table Scale with a 10-inch touchscreen and MiniERP software for guided weighing and lot-number traceability, while centralized plant control cabinets employ 15-inch HMI panels, built-in SQL databases and bidirectional ERP links (including Microsoft Dynamics NAV and PCS Winbag) plus parallel-control retrofits that modernize legacy dosing lines without stopping production.

The Dose-Track IoT platform records batch accuracies, material consumption and line usability for preventive maintenance, while the RFID-based Dough Guardian system tracks dough resting times across movable bowls.

When ordering equipment configurations or replacement parts — such as dosing augers, load cells, 0.15-10 mm perforated sifter drums, SGS food-safe Fluidiser fabrics, Cyclone Filter and DEU850 cartridges, Fluidmatic pumps or PLC/HMI modules — specify the machine model, serial number from the Powder Technic Ltd / Powdea Technologies Oy nameplate and target capacity.
