PRODUCTS

Processing equipment we design, build, and support.

Alongside our design and simulation services, Norvik Systems manufactures hot-air processing equipment for the snack, nut, seed and popcorn industries — engineered around the same hot-air principle across every platform.

SHARED TECHNOLOGY

Pure Hot Air, Not Salt or Sand

A perforated drum tumbles the product bed while hot air is drawn through it, transferring heat evenly across every particle. Temperature is closed-loop controlled and rotation speed is adjustable, so dwell time and roast intensity can be tuned precisely to each product.

  • Material of construction: SS304 stainless steel throughout
  • Maximum operating temperature: 250°C
  • Energy source: LPG / CNG / PNG burners, thermic fluid, or steam
  • Fully washable design for food-safety compliance
  • No salt or sand used as a heat-transfer medium
Hot-air heat transfer cross-section: hot air drawn through the rotating drum and product bed
Hot-air heat transfer & roasting cross-section — shared by both platforms below

SEE THE DIFFERENCE

Same batch, two very different results

Drag the slider — conventional salt/sand roasting scorches some product while leaving the rest undercooked. Norvik's hot air reaches every particle the same way, every time.

CONTINUOUS DRYER, ROASTER & PUFFER

The Hot Air Rotary Oven

Turn raw ingredients into perfectly roasted products — no salt, no sand, no guesswork.

A perforated-drum rotary oven for continuous processing of snacks, nuts and seeds, where uniform cooking, drying, roasting or puffing is required. The drum's perforations let hot air pass through and penetrate the product bed, giving efficient heat transfer and even results batch after batch.

MACHINE COMPONENTS

Storage HopperBuffers incoming product ahead of the infeed for a steady, controlled feed rate.
Infeed FeederMeters product into the drum at a consistent, adjustable rate.
Heating ZonePerforated rotating drum where hot air circulates through the tumbling product bed.
Heat Transfer ZoneInsulated hood directs and recirculates hot air across the drum length.
Output / UndersizeFinished product discharges to output; fines and undersized particles are separated out.

INTEGRATED ELEVATOR-TO-PACK-READY LINE

Roasting & Seasoning Line

A complete continuous production line — elevator to pack-ready output in one pass.

The Roasting & Seasoning Line carries product through every stage in one continuous flow: a vertical elevator lifts raw kernels or nuts into the roaster without spillage; the roasting drum uses the same shared hot-air principle; a vibratory siever removes dust and fines to size; and a custom helical seasoning tumbler coats the product with zero breakage and over 95% coverage before a final conveyor hands it off to packing.
