Dairy & Protein Powder
Solutions
Sanitary powder processing systems engineered for milk powder, whey protein, plant protein, nutritional supplements, and meal replacement powders -- built to food-grade hygienic standards.
Hygienic Design at Every Stage of the Process
Yinda provides complete sanitary powder processing systems designed specifically for dairy and protein-based products. Every contact surface is manufactured from stainless steel with polished internal structures, minimising residue retention and ensuring thorough cleanability between product changeovers.
Our systems are engineered to comply with food-grade hygienic standards, addressing the strict requirements of dairy and nutritional supplement manufacturing -- from particle size consistency and flowability control to dust containment and automated line integration.
Designed to Eliminate Contamination Risk
Special attention is given to hygiene at every design stage -- no dead zones, smooth welding seams, and optimised internal geometry to prevent product accumulation and cross-contamination.
No Dead Zones
All internal surfaces and transitions are engineered to eliminate stagnant zones where product or moisture can accumulate between cleaning cycles.
Polished Internal Surfaces
Contact surfaces are mechanically polished to food-grade standards, reducing bacterial adhesion and enabling faster, more effective CIP and WIP cleaning.
Smooth Continuous Welding
All weld seams are continuously ground and polished. No crevices or rough weld beads that could trap product residue or harbour microbial growth.
Fast Disassembly & Cleaning
Designed for rapid tool-free or minimal-tool disassembly to support frequent product changeovers with minimal downtime between production runs.
SS304 / SS316L Construction
All product-contact components are manufactured from SS304 or SS316L stainless steel, selected based on the specific corrosion and hygiene requirements of the application.
Closed-Loop Dust Containment
Integrated dust collection and sealed transfer points prevent protein and dairy powder from escaping the process stream, protecting operators and maintaining yield.
Complete Powder Processing for Dairy & Protein
Our systems ensure uniform particle size distribution, stable flowability, and low dust generation throughout the production process.
Size Reduction & Milling
Precision milling systems for dairy and protein powders requiring consistent particle size distribution. Suitable for deagglomeration, fine grinding, and controlled comminution of heat-sensitive protein materials.
- Pin Mill (Needle Mill)
- Air Classifier Mill
- Hammer Mill
- Low-Temperature Milling Option
Screening & Classification
Post-milling screening to remove oversize particles, foreign material, and agglomerates. Ensures consistent particle size before mixing or packaging, and protects downstream equipment.
- Vibrating Screen
- Multi-deck Classification
- Oversize Removal
- Pre-packaging Quality Check
Powder Blending & Mixing
Hygienic mixing systems for blending dairy bases, protein concentrates, vitamins, minerals, and functional ingredients into homogeneous nutritional formulations with validated blend uniformity.
- Ribbon Blender
- V-Blender
- Double Cone Mixer
- IBC / Bin Blender
- Liquid Addition Option
Conveying & Transfer
Enclosed powder transfer systems that maintain product integrity and hygiene between processing stages. Minimises manual handling, reduces contamination exposure, and supports automated line integration.
- Pneumatic Conveying
- Screw Conveyor
- Bucket Elevator
- Sealed Bin Transfer
- Dust-Free Connections
Automated Production Line for Dairy & Protein Powder
The system can be integrated with grinding, mixing, conveying, and screening equipment to form a complete automated production line -- from raw material intake to finished powder packaging.
Uniform Particle Size
Consistent PSD across batches for reliable product texture and dissolution performance.
Stable Flowability
Optimised process parameters maintain stable bulk density and flow characteristics for filling and packaging.
Low Dust Generation
Enclosed process design and integrated dust collection minimise airborne powder loss and operator exposure.
Fast Changeover
Tool-free or minimal-tool disassembly enables rapid cleaning and product changeover to reduce line downtime.
Contamination Control
No dead zones, smooth welds, and sealed transfers work together to minimise cross-contamination risk.
Batch Traceability
PLC-based control systems support batch record management and production data logging.
What Our Dairy & Protein Systems Deliver
Beyond equipment supply, Yinda focuses on the outcomes that matter to dairy and protein powder manufacturers -- consistent product quality, reliable production throughput, and hygienic operation that meets food safety expectations.
Every system is configured based on your specific material characteristics, production targets, and hygiene requirements -- not a generic catalogue selection.
"We start with your material -- its moisture, particle structure, flowability, and heat sensitivity -- before recommending any equipment configuration."

SS304 / SS316LTest Your Dairy or Protein Material Before Committing
Dairy and protein powders vary significantly in moisture content, particle structure, flowability, and heat sensitivity. We recommend material testing before equipment selection to validate milling performance, particle size distribution, and yield.
- Verify achievable particle size and PSD
- Measure temperature rise during milling
- Assess flowability and bulk density
- Evaluate dust generation levels
- Confirm material recovery rate
- Validate cleaning and residue behaviour
