Food sieve MPAK

solid particle separationmaterial separationfor flour

Overview
The Sirius plansifter MPAK sieves and grades wheat, rye, maize (corn), durum, oats, barley and soybean products. It features a modular construction for scalable capacity, NovaPur polyurethane sieve stacks with stainless-steel inlay and design elements that simplify cleaning and maintenance.

Key benefits

• Flexible modular design — Modules available with 2, 4, 6, 8 or 10 sifter compartments; modules can be combined or expanded to match production needs.
• Hygiene and food-safety features — Product-contact parts made of stainless steel and polyurethane; no wooden parts or screw fasteners in product zones; insulation to prevent condensation; automatic reclamping to avoid cross-contamination.
• Reduced maintenance — Poly-V drive belt and durable bearing assemblies extend maintenance intervals; overall cleaning and maintenance effort reduced by ~30% with NovaPur reducing sieve cleaning effort by up to ~60%.

Highlight features

• NovaPur sieve stacks — PUR frame with stainless-steel inlay, hygienic design without wood, screws or nails in product areas.
• Low residue design — NovaPur geometry leaves minimal flour residues in sieves, simplifying cleaning and lowering downtime.
• Expandable module concept — Select required number of sifter compartments per module and add modules later for capacity increase.

Application possibilities

• Wheat
• Corn (maize)
• Durum
• Rye
• Oats
• Barley
• Soybean products

Role in the milling process

• Intake and pre-cleaning — removes impurities and protects downstream equipment.
• Cleaning and conditioning — contributes to contaminant removal and correct moisture/conditioning before milling.
• Milling — integrates with roller mills and sifters to control flour properties and separate bran/semolina fractions.
• Blending and packing — provides graded fractions for downstream storage, blending or bagging operations.

Services & training
Service packages, upgrades, retrofit options and operator training are available to ensure correct operation, efficient maintenance and optimal performance over the equipment lifecycle.
