A Whey Processing Plant turns cheese, paneer or casein whey — once an effluent problem — into high-value products: whey protein concentrate (WPC), lactose, and demineralised whey powder. Whey is clarified and pasteurised, concentrated by ultrafiltration to raise protein, then evaporated and spray-dried into powder, while the permeate yields lactose.
ATMAN Group designs and executes whey processing plants across the full capacity spectrum — from compact units recovering whey from a single cheese or paneer line, up to large WPC and lactose plants for federations and protein-ingredient brands.
Every plant integrates clarification, UF and RO membranes, evaporation and drying into one synchronised line — matched fouling control, thermal load and batch-to-pack traceability.
Whey is the dairy industry’s biggest hidden asset — a high-protein stream most plants still dump as effluent. A well-engineered recovery line is the difference between saleable WPC and lactose and a GPCB compliance headache. ATMAN sizes membranes, evaporation and drying around your whey volume and target product.

Whey processing — WPC and lactose recovery flow — ATMAN Group
Whey Processing — From Whey to WPC and Lactose
A whey processing plant runs as a membrane-and-dry line: whey is clarified and pasteurised, concentrated by ultrafiltration to raise protein, optionally diafiltered, then evaporated and spray-dried into WPC powder, while the permeate is processed for lactose.
01. Whey Reception
Whey from cheese, paneer or casein production is collected, weighed and chilled, then screened to remove curd fines.
06. Evaporation
The retentate is concentrated by reverse osmosis or a vacuum evaporator to raise total solids before drying.
02. Clarification
Whey is clarified by centrifuge to remove residual fat and fine curd particles before membrane processing.
07. Spray Drying
Concentrate is atomised into hot air in the spray dryer, instantly removing moisture to form whey protein powder.
03. Pasteurisation
Clarified whey is pasteurised at around 72 degrees C and cooled to protect the membranes and ensure food safety.
08. Fluid-Bed Drying
Powder is dried and cooled on a vibro fluid-bed, building free-flowing, low-moisture WPC.
04. Ultrafiltration (UF)
Ultrafiltration membranes concentrate the whey, retaining protein as retentate while lactose and minerals pass into the permeate.
05. Standardization
The protein retentate is standardised to the target grade — WPC 35, 60 or 80 — before concentration and drying.
09. Sifting and Packing
Powder is sifted and packed into bags or tins with nitrogen flush and metal detection.
10. Dispatch / Packing Feed
WPC is packed and dispatched; the lactose-rich permeate is crystallised and dried for lactose recovery.
ATMAN engineers the full whey-recovery line as one integrated flow — from whey reception through ultrafiltration, drying and lactose recovery — sized to your whey volume and target product.

Capacity Options — From Compact to Industrial Scale
ATMAN engineers whey processing plants sized to your daily whey volume and target product — WPC 35, 60 or 80, lactose, or demineralised whey — matching membrane area, evaporation and drying to your output.
Whey looks like waste — until you recover it. The reality: membranes foul, protein denatures, and effluent fines hammer your GPCB compliance if the line is wrong. Membrane and drying control are where engineering depth pays off. Here is what makes ATMAN the right partner.
Most equipment suppliers stop at the machine. ATMAN engineers the processing core and downstream packing as one system — matched piping, aligned CIP cycles, unified batch tracking. Zero split-vendor finger-pointing.
02
Single-Window Turnkey Execution
Design through commissioning and AMC under one contract. One team to call when the line throws an error at 2 AM. One accountable partner for plant uptime — not a vendor patchwork.
Whey valorisation is a membrane-and-thermal discipline. UF and RO design, fouling control, evaporation and spray drying are baked into our playbooks since 2008.
05
Compliance-First Engineering
All plants engineered for FSSAI, BIS-rated electricals, GPCB-norm effluent, and 3-A sanitary process design. Statutory audits pass first time — no costly retrofits later.

Whey Processing Plant — FAQ
Capex varies with capacity, target product (WPC grade, lactose) and membrane area. A compact UF-only line starts modestly; full WPC-plus-lactose plants with evaporation and spray drying run into tens of crores. ATMAN sizes membranes, evaporation and drying to your whey volume and product to avoid over-capitalising.
Typically 8 to 14 months from design freeze to commissioning, depending on capacity, membrane and drying scope, and civil readiness. ATMAN runs design, fabrication and civil in parallel to compress the schedule.
Start by recovering whey from your existing cheese or paneer output, sizing UF to that volume, with headroom to add evaporation, drying and lactose recovery as demand grows.
Mandatory: FSSAI licence (central or state by turnover), GPCB / state pollution-board consent, municipal NOC, factory licence, fire NOC, and electricity sanction. Recommended: ISO 22000, HACCP, and BIS where applicable. ATMAN engineers plants for full compliance by default — no costly retrofits after commissioning.
Footprint scales with capacity and product mix — membrane skids are compact, but evaporation and spray drying need height. ATMAN provides a layout sized to your capacity and products.
WPC (whey protein concentrate) is 35 to 80 percent protein dried whey; WPI (isolate) is 90 percent plus protein via microfiltration or ion exchange; lactose is the milk sugar recovered from the permeate. ATMAN engineers the line for your target product mix.
