Yogurt and Doogh Production Line and Factory Setup

A yogurt and doogh production line is a complete industrial system designed to transform milk into finished yogurt and doogh (yogurt drink) under controlled process conditions. The line produces set or stirred yogurt and flavoured doogh ready for packaging and distribution.

From an industrial perspective, yogurt manufacturing is important because it combines milk reception, pasteurization, homogenization, inoculation and fermentation, cooling, filling and CIP. The process relies on a defined sequence of unit operations that must be correctly engineered, sized and integrated.

Primary raw materials typically include milk, starter culture, milk powder, sugar, fruit, stabilizers and packaging materials. The core machinery set consists of pasteurizers (500–5000 L/h), homogenizers (1000–5000 L/h), fermentation tanks (1000–10 000 L), filling machines (2000–12 000 containers/h) and CIP systems.

The Industrial Department supports investors who want to establish a new yogurt plant as well as existing plant owners who need repair, overhaul, capacity expansion or automation of their current lines. Projects can start from an empty site or from an operating facility that requires technical upgrading.

Whether the goal is a green-field turnkey plant in Iraq, Kurdistan Region, Afghanistan or other regional markets, or the modernization of an existing line in Iran, engineering, machinery supply or manufacturing, installation, commissioning and ongoing technical support can be provided under defined contractual scopes.

Production Line Overview

The yogurt and doogh production line is engineered as an integrated process system covering milk reception, pasteurization, homogenization, fermentation, cooling, filling and packaging. Design capacity is determined during the engineering phase and can typically range from pilot or semi-industrial scales up to higher industrial throughputs, depending on final product mix and market requirements.

Product types include set yogurt, stirred yogurt and doogh (yogurt drink). The overall process flow follows a defined sequence: milk reception, pasteurization (85–95 °C), homogenization, inoculation and fermentation, cooling, filling and packaging.

Main machinery groups include pasteurizers, homogenizers, fermentation tanks, filling machines and CIP systems. Supporting infrastructure covers electrical power (100–300 kW), steam (300–800 kg/h) and water (10–30 m³/day).

Manpower requirements depend on the degree of automation (typically 8–15 persons per shift). Quality control covers acidity, texture, flavour and packaging integrity. Finished products are stored under refrigerated conditions before distribution.

Technical Specifications

All figures are indicative. Detailed utility balances, equipment lists and layout drawings are prepared after process definition and capacity confirmation.

Products

An industrial yogurt and doogh production line can manufacture set yogurt, stirred yogurt and flavoured doogh depending on formulation and process parameters. Packaging formats are selected according to target markets.

Raw Materials for Yogurt and Doogh Factory

Raw material selection and quality control are critical for texture, flavour and shelf life. The main materials are milk, starter culture, milk powder, sugar, fruit and stabilizers.

Manufacturing Process

1. Milk Reception – Raw milk is received, analysed and stored.
2. Pasteurization – Milk is pasteurized at 85–95 °C (500–5000 L/h).
3. Homogenization – Milk is homogenized (1000–5000 L/h).
4. Fermentation – Inoculated milk is fermented in tanks (1000–10 000 L).
5. Cooling, Filling and Packaging – Product is cooled, filled (2000–12 000 containers/h) and packaged.

Machinery & Equipment

• Pasteurizer – Heat-treats the milk. Position: after reception. Importance: foundation of product safety. Quality impact: temperature and holding time control microbial quality. Maintenance: plates, gaskets and controls. Sahi Rasa Support: design, manufacturing/procurement, installation, repair, overhaul and automation.
• Homogenizer – Reduces fat globule size. Position: after pasteurization. Quality impact: texture and stability. Maintenance: valves, pistons and seals. Sahi Rasa Support: design, installation, repair and spare parts.
• Fermentation Tank – Holds product during fermentation (1000–10 000 L). Position: core of the process. Importance: determines acidity and texture development. Quality impact: temperature and time control quality. Maintenance: jackets, agitation and CIP. Sahi Rasa Support: design, installation, repair and overhaul.
• Filling Machine and CIP System – Fill the product and clean the line. Position: end of line / supporting. Quality impact: fill accuracy, hygiene and package integrity. Maintenance: dosing systems and CIP circuits. Sahi Rasa Support: installation, repair and spare parts.

Factory Layout & Building Requirements

Typical functional areas include milk reception, processing (pasteurization, homogenization, fermentation), filling and packaging, cold storage, CIP, utility rooms, maintenance workshop, staff facilities and loading docks. Layout must respect hygienic zoning and process flow. Exact area allocation is determined during the engineering phase according to capacity.

Utilities

• Electricity: 380 V three-phase, typically 100–300 kW
• Steam: 300–800 kg/h
• Water: 10–30 m³/day
• Refrigeration and hygiene controls according to local regulations

Turnkey Factory Setup

An investor can start from an empty site. Depending on contractual scope, the project can be accompanied through: Idea → Feasibility → Engineering → Factory Design → Machinery → Procurement → Manufacturing → Installation → Commissioning → Training → Raw Material Supply → Packaging → Trial Production → Commercial Production. The objective is an operational factory ready for production.

EPC & PMC

Projects can be executed under EPC or PMC approaches. Engineering, machinery supply or manufacturing, installation supervision and commissioning are coordinated within the defined contract boundaries.
