Turnkey lassi, chaas and cultured buttermilk plants — fermentation, blending and pouch, PET or cup packing. Design, supply, installation, commissioning & after-sales.
A Lassi and Buttermilk Plant produces cultured, ready-to-drink dairy beverages — sweet and fruit lassi, plain and masala chaas, and cultured buttermilk. Milk is standardised, pasteurised and homogenised, then cultured or built on a curd base, blended with sugar, fruit or spices, cooled, and filled into pouches, bottles or cups.
ATMAN Group designs and executes lassi and buttermilk plants across the full capacity spectrum — from compact 1,000 LPD units for regional dairies and FPOs, up to 200,000 LPD high-speed cultured-beverage lines for federations and major beverage brands.
Every plant integrates the wet process, fermentation tanks, blending vats and fillers as one synchronised line — matched culture management, cold-chain, and recipe-to-pack traceability.
Lassi and chaas are among the highest-margin, fastest-moving dairy SKUs in the Indian summer — and quality lives in the culture and the cold-chain. A well-engineered fermentation-and-blending line is the difference between a smooth, stable, consistent drink and losses from syneresis, flavour drift and short shelf life. ATMAN sizes fermentation, blending and filling around your recipe mix and peak-season volume.

10-stage lassi & buttermilk processing flow — ATMAN Group
Lassi and Buttermilk Production — From Reception to Packing
A lassi and buttermilk plant runs as a culture-and-blend line: milk is received, standardised, pasteurised and homogenised, cultured or curd-based, blended with sugar, fruit or spices, then cooled and filled under hygienic, cold-chain-ready conditions.
01. Milk Reception
Raw milk arrives by road tanker, is weighed, sampled and chilled to 4 degrees C in insulated silos before processing.
06. Pasteurization
The standardised mix is pasteurised at 90 to 95 degrees C — the high heat-treatment cultured dairy drinks need for body and shelf life.
02. Quality Testing & Standardization
Fat, SNF, acidity and adulterants are tested; the milk is standardised to the fat and SNF the target beverage requires.
07. Homogenization
The mix is homogenised at 150 to 200 bar to give lassi and buttermilk a smooth, stable, non-separating texture.
03. Clarification & Chilling
Milk is clarified to remove sediment and somatic cells, then chilled and held ready for the culturing or blending base.
08. Culturing and Fermentation
The cooled mix is inoculated with selected lactic cultures and incubated at around 42 degrees C until target acidity and flavour develop; sweet lassi can instead be built on a fresh curd base.
04. Cream Separation
A high-speed centrifugal separator sets the fat level — lean for chaas and buttermilk, richer for sweet lassi.
05. Standardization
Skim and cream are re-blended to the exact fat and SNF target for the beverage — lean for chaas, richer for lassi — before heat treatment.
09. Blending and Flavouring
The cultured base is blended with sugar syrup, fruit pulp, or salt and spices — sweet, mango, plain or masala — to recipe, then chilled.
10. Dispatch / Packing Feed
Finished beverage cooled and filled into pouches, PET bottles or cups — ready for chilled dispatch and modern-trade or institutional supply.
ATMAN engineers the full culture-and-blend line as one integrated flow — from milk reception through fermentation, flavouring and chilled filling — sized to your SKU mix and peak-season volume.

Capacity Options — From Compact to Industrial Scale
ATMAN engineers lassi and buttermilk plants across capacities from 1,000 to over 200,000 LPD — sizing fermentation, blending and filling to your SKU mix and peak-season demand.
Cultured beverages look simple — ferment and pack. The reality: inconsistent culture control, syneresis, flavour drift and a weak cold-chain quietly kill shelf life and repeat sales. Process control is 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.
Cultured-beverage manufacture is a fermentation-led discipline. Culture management, acidity control, homogenisation and cold-chain design 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.
06
Modular Scalability Built-In
Initial plant designed with utility and floor headroom for additional fermentation and filling capacity. Scale-up is planned into the Day-1 layout.
Typical 5–9 month execution timeline — 7 phases
Project Execution — From Day Zero to First Litre Processed
A typical ATMAN lassi and buttermilk plant project runs through four disciplined phases — from design freeze to first packed bottle.

Lassi and Buttermilk Plant — FAQ
Capex varies with capacity, SKU mix, packing format and automation. A compact pouch-chaas line starts in the low crores; high-speed multi-SKU lassi and buttermilk lines with PET and cup filling run higher. ATMAN sizes fermentation, blending and filling to your volume and pack mix to avoid over-capitalising.
Typically 5 to 9 months from design freeze to commissioning, depending on capacity, packing format and civil readiness. ATMAN runs design, fabrication and civil in parallel to compress the schedule.
Start with the capacity that comfortably covers your assured milk supply and summer-peak demand, with headroom to add SKUs and filling lines as the brand grows. Cultured beverages are seasonal, so size for peak, not average.
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 pack formats — roughly 2,000 to 6,000 sq ft for a mid-size line including process, fermentation, filling, cold storage and utilities. ATMAN provides a layout sized to your capacity.
Lassi is a thick, sweet or fruit blended yogurt drink; chaas and cultured buttermilk are thin, tangy, lightly salted or spiced drinks. All share the same culture-and-blend core — ATMAN engineers the line for your recipe and pack mix.
