Curd & Yogurt Plant Manufacturer

A Curd & Yogurt Plant converts standardised milk into set curd (dahi), stirred yogurt, and Greek-style yogurt. It standardises and pasteurises the milk, homogenises it, cools it to incubation temperature, inoculates it with starter cultures, then incubates, cools, and packs the product for cold-chain distribution.

ATMAN Group designs and executes curd and yogurt plants across the full capacity spectrum — from compact set-curd lines for regional dairies and FPOs, up to high-volume automated cup-filling and incubation lines for large brands running multiple shifts daily.

Every curd/yogurt line draws standardised milk from the upstream milk plant and integrates culture handling, incubation, cup-filling, and cold chain — with matched sanitary piping, compatible CIP cycles, and synchronized batch tracking. Plants are FSSAI-compliant by default, with hygienic SS-304 stainless steel construction throughout the wet section per BIS and 3-A sanitary standards.

Curd and yogurt are among the fastest-growing dairy categories — and set quality, consistency, and shelf life define the brand. A well-engineered line is the difference between firm, uniform set and losses from wheying-off, weak body, and inconsistent acidity. ATMAN’s integrated approach designs the line with culture management and cold chain pre-mapped.

Typical Buyers We Work With

ATMAN builds curd and yogurt plants for the full B2B dairy spectrum — cooperatives, FPOs, private dairy brands, and integrated greenfield projects.

01. Milk Reception

Fresh milk received, weighed, and tested for fat, SNF, and quality. Chilled and held until the curd batch begins.

06. Culture Inoculation

Selected starter cultures (S. thermophilus, L. bulgaricus, or dahi cultures) dosed for consistent acidity and flavour.

02. Standardisation

Milk standardised to target fat/SNF — often fortified with SMP for the firm body that set curd and yogurt require.

07. Cup Filling

For set curd, inoculated milk is filled into cups or pouches before setting; stirred yogurt is incubated in tank first.

03. Pasteurisation

Milk pasteurised at 85–90°C — hotter and longer than drinking milk — to denature whey proteins for a firm, stable set.

08. Incubation

Held at 42–45°C for 4–6 hours until target acidity (pH ~4.5) and a firm set develop.

04. Homogenisation

Homogenised at 150–200 bar to prevent wheying-off and deliver a smooth, uniform curd texture.

05. Cooling

Cooled to the inoculation temperature of 42–45°C — the optimal range for the yogurt and dahi starter cultures.

09. Blast Cooling

Rapidly cooled to 4°C to arrest fermentation, locking texture, acidity, and shelf life.

10. Cold Storage & Dispatch

Packed curd / yogurt moved to cold storage and dispatched under cold chain. CIP cycle starts for the next batch.

Why ATMAN for Your Curd & Yogurt Plant

Curd looks simple — heat milk, add culture, set. The reality: weak set, wheying-off, and inconsistent acidity quietly destroy texture, shelf life, and brand trust. Culture and incubation control is where engineering depth pays off. Here’s what makes ATMAN the right partner.

Project Execution — From Day Zero to First Set Cup

A typical ATMAN curd / yogurt plant project runs 3 to 6 months from kickoff to first set cup. We execute in seven structured phases with continuous client visibility into each milestone.
