Snack food manufacturing continues to evolve as producers respond to growing consumer demand for convenience, product variety and consistent eating experiences. From crisps, cereals and coated nuts to extruded snacks and seasoned products, manufacturers are increasingly working with a wide range of powders, inclusions and functional ingredients that must be handled accurately and consistently throughout production.

Seasoning powders, starches, coatings and inclusions all introduce unique processing challenges. Fine powders can generate dust, segregate or compact during storage, while fragile ingredients may break down during transfer, creating fines and impacting final product quality. Managing these behaviors while maintaining throughput, consistency and hygiene standards has become a critical focus for snack manufacturers.

Processing expectations are rising across the dairy sector

Modern snack manufacturers are expected to deliver far more than high-volume output alone. Production environments must also support:

• Frequent product changeovers and short production runs
• Consistent flavor application and blend uniformity
• Reliable handling of fragile or irregular ingredients
• Cleaner processing environments with reduced dust generation
• Flexible systems capable of supporting multiple SKUs and evolving product ranges

These demands are driving increased adoption of integrated material processing systems that combine controlled ingredient feeding, enclosed conveying, screening and repeatable blending.

Understanding material handling challenges in snack production
Snack ingredients behave differently depending on their composition, particle size and moisture sensitivity. These material characteristics can directly influence production efficiency and product consistency.

Powder segregation and inconsistent flavor distribution
Seasoning blends and fine powders can separate during transfer or storage, affecting flavor consistency across finished products.

Dust generation in fast-paced production environments
Many seasoning powders create airborne dust during handling, requiring enclosed systems and controlled ingredient feeding points to support cleaner production.

Product degradation during conveying
Fragile inclusions such as cereals, nuts and coated snack components can break during transfer, reducing product quality and generating excess fines.

Flow interruptions caused by bridging or compaction
Powders and starches may compact during storage, affecting discharge consistency and downstream equipment performance.

Addressing these challenges requires a coordinated processing approach that combines reliable ingredient feeding, gentle conveying, effective screening and controlled blending.

Key considerations when designing a snack food processing system

Key considerations when designing a snack food processing system:

• Controlled feeding and discharge of bulk ingredients
• Enclosed transfer between process stages
• Screening and particle conditioning
• Uniform blending of powders and particulates
• Transfer to packaging or downstream production equipment

Akona Process Solutions supports these stages using complementary technologies from Spiroflow, Cablevey, Kason and Marion.

Here’s a closer look at each stage and the equipment that supports it:

1. Ensuring reliable ingredient intake

• Spiroflow Bulk Bag Dischargers

Bulk bag systems are commonly used for high-volume snack ingredients including seasoning blends, flours, starches and functional powders. Engineered bulk bag dischargers provide controlled and consistent feeding into downstream processes while helping reduce manual handling and dust exposure.

• Akona Bag Dump Stations

Manual addition remains important for seasoning blends, minor ingredients and recipe adjustments. Hygienically designed bag dump stations provide cleaner loading conditions with integrated screening, dust collection and containment options to support controlled ingredient handling.

2. Maintaining product quality during conveying

• Spiroflow Flexible Screw Conveyors

Flexible screw conveyors provide enclosed transfer of powders and blends between feeding, screening and mixing stages. Compact designs and quick-release features support efficient cleaning and reduced downtime during product changeovers.

• Cablevey Tubular Drag Conveyors

For fragile snack products such as cereals, crisps, nuts and coated inclusions, tubular drag conveyors provide gentle handling that helps minimize product breakage and fines generation. Fully enclosed systems with optional clean-in-place capabilities support hygienic operation in demanding production environments.

3. Screening and flow conditioning as quality safeguards

• Kason Vibratory Screeners

Vibratory screening systems help remove foreign material, reduce agglomerates, and support consistent particle-size distribution in seasoning blends and powdered ingredients.

• Kason Multi-Deck Vibratory Sifters

Where tighter classification control is required, multi-deck screening systems separate powders into multiple fractions in a single pass, supporting improved seasoning consistency and product appearance.

• Kason Centrifugal Sifters

Centrifugal sifters provide efficient, continuous screening for higher-throughput snack operations while maintaining gentle handling of fine powders.

4. Delivering consistent blending performance

• Marion Horizontal Mixers

Uniform blending is essential to achieve consistent flavor delivery and repeatable product quality across snack production lines. Horizontal mixers provide rapid, uniform blending of powders and particulates while supporting efficient cleaning through hygienic designs and optional clean-in-place capabilities.

Integrated systems supporting modern snack production

As snack manufacturers continue to expand product ranges and increase production flexibility, processing systems must balance throughput, consistency and operational reliability. By integrating ingredient feeding, conveying, screening and blending into a coordinated material processing system, manufacturers can better manage ingredient behavior while supporting cleaner production, reduced waste and more consistent product quality.

Through technologies from Spiroflow, Cablevey, Kason and Marion, Akona Process Solutions delivers engineered systems designed to support efficient, hygienic and repeatable snack food production.
