Dairy and dairy alternative manufacturing is evolving rapidly as producers respond to changing consumer expectations around nutrition, functionality and convenience. Milk powders, whey proteins, lactose, caseinates and plant-based blends are increasingly used across a wide range of applications, from sports nutrition and ready-to-drink products to bakery, confectionery and prepared foods.

As product portfolios grow, so does the complexity of processing these materials. Many dairy ingredients are hygroscopic, fine and highly sensitive to handling conditions. They can compact in storage, generate dust during transfer or form agglomerates that disrupt conveying and mixing performance. Managing these behaviors while maintaining strict hygienic standards is now a defining operational challenge for the sector.

Processing expectations are rising across the dairy sector

Manufacturers today must deliver more than simple throughput. They are expected to maintain consistent product quality while supporting:

• Frequent recipe changes and shorter production campaigns
• Expanded ranges of fortified and functional products
• Traceability and contamination-control requirements
• Efficient cleaning and validation procedures

These pressures are encouraging a shift toward integrated material handling systems that combine controlled intake, sanitary conveying, precision screening and repeatable blending.

So what are the powder handling realities in dairy environments?

Fine dairy powders introduce several processing considerations that directly influence plant efficiency:

Flow variability linked to moisture uptake
Changes in humidity can affect bulk density and discharge behavior, creating unstable feed conditions.

Dust management as part of hygienic design
Enclosed transfer and controlled intake points help reduce airborne powder and support cleaner production zones.

Agglomeration affecting downstream performance
Compacted material can interrupt conveying, reduce mixing uniformity and increase the risk of batch inconsistency.

Addressing these issues requires a coordinated approach that considers both equipment design and overall system integration.

Key aspects to consider when structuring a dairy powder processing line

A typical hygienic processing workflow includes:

• Intake and discharge of bulk ingredients
• Enclosed transfer between process stages
• Screening and size conditioning
• Controlled blending
• Transfer to packaging or further manufacturing

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. Establishing reliable intake conditions

• Spiroflow Bulk Bag Dischargers

Bulk bag systems are widely used for high-volume dairy powders such as milk solids, proteins and lactose. Engineered discharge units provide stable feeding into the process while reducing manual handling and exposure to dust.

• Akona Bag Dump Stations

Manual addition remains essential for cultures, stabilisers and minor ingredients. Hygienically designed dump stations enable contained loading with integrated screening and dust control options, helping maintain product integrity during recipe preparation.

2. Maintaining product integrity during transfer

• Spiroflow Flexible Screw Conveyors

Flexible screw conveyors provide enclosed transfer of powders between intake, screening and blending stages. Their compact design and smooth internal finishes support reliable movement of moisture-sensitive materials in space-constrained dairy facilities.

• Cablevey Tubular Drag Conveyors

For delicate particulates or premium dairy blends, tubular drag conveying offers gentle handling and fully enclosed transport. Clean-in-place configurations and adaptable routing make these systems suitable for complex hygienic processing layouts.

3. Screening and flow conditioning as quality safeguards

• Kason Vibratory Screeners

Vibratory screening helps remove foreign material, reduce agglomerates and support consistent particle size prior to blending or packaging.

• Kason Centrifugal Sifters

Centrifugal sifters enable continuous screening performance in higher-throughput dairy powder operations while maintaining gentle separation characteristics.

• Kason Lump Breakers

Lump breakers restore flowability after storage or transport, helping maintain stable conveying and mixing conditions.

4. Delivering consistent blending performance

• Marion Horizontal Mixers

Uniform blending is essential to ensure consistent nutritional performance, taste and functionality in dairy and plant-based products. Horizontal mixers provide rapid, repeatable batch results while supporting hygienic operation through cleanable designs and optional clean-in-place capability.

Integrated systems supporting dairy innovation

As dairy and dairy alternative markets continue to diversify, manufacturers require processing solutions that balance flexibility with hygiene and operational reliability. By linking intake, conveying, screening and blending into a coordinated system, producers can better manage powder behavior while maintaining consistent product quality.

Through technologies from Spiroflow, Cablevey, Kason and Marion, Akona Process Solutions helps dairy processors implement material handling systems engineered for sanitary performance, repeatability and long-term production efficiency.
