From Cooling to Packaging: An Integrated Milk Packaging Solution

Milk is one of the most delicate food products, highly sensitive to temperature, hygiene, and processing conditions. For small and medium-sized dairy businesses, selecting the right milk processing and packaging equipment is critical to ensuring product quality, food safety, and commercial success.

This article introduces a complete milk production and packaging solution, covering milk cooling tanks, pasteurization systems, semi-automatic filling machines, and fully automatic aseptic packaging machines.

1. Milk Cooling Tank

Immediately after milking, raw milk must be cooled quickly to prevent bacterial growth and preserve freshness.

Key functions of a milk cooling tank include:

• Rapid cooling performance using efficient heat exchange systems
• Stable low-temperature storage, typically maintaining milk at 0–4 °C
• Food-grade construction, made of SUS304 stainless steel
• Automatic stirring and CIP cleaning system to ensure uniform cooling and hygiene
• Energy-efficient insulation to reduce power consumption

Milk cooling tanks are widely used in dairy farms, milk collection centers, and small dairy processing plants as the first step in the production chain.

2. Pasteurization & Cooling Tank

Pasteurization is a critical step in milk processing. By heating milk to a controlled temperature and then rapidly cooling it, harmful microorganisms are eliminated while nutritional value is retained.

Advantages of pasteurization tanks:

• Integrated heating and cooling functions for efficient processing
• Precise temperature control suitable for different dairy products
• Compact design ideal for small-batch production
• Full stainless-steel structure compliant with food safety standards
• Compatible with CIP cleaning systems

This type of equipment is ideal for producing fresh milk, yogurt, and other short-shelf-life dairy products.

3. Gable Top Carton Filling Machine – Cost-Effective Packaging

For startups and growing dairy brands, semi-automatic carton filling machines provide a practical and economical packaging solution.

Main features include:

• Integrated functions: carton forming, bottom sealing, liquid filling, top sealing, and date coding
• Wide temperature adaptability, supporting both cold filling and hot filling
• Flexible volume range, commonly from 200 ml to 2000 ml
• Suitable for milk, yogurt, cream, and other liquid dairy products

This type of machine offers a balance between affordability and functionality, making it an excellent choice for small to medium-scale production.

4. Fully Automatic Aseptic Filling & Packaging Machine – For Industrial Production

As production capacity grows and shelf-life requirements increase, fully automatic aseptic packaging machines become essential.

Key advantages of fully automatic systems:

• Complete automation, including carton forming, sterilization, aseptic filling, sealing, and conveying
• Aseptic environment control, ideal for UHT milk and long-life dairy products
• High efficiency, capable of thousands of cartons per hour
• User-friendly control system with touch-screen operation and precise filling accuracy
• Reduced labor costs and consistent product quality

These machines are widely used in medium to large dairy factories and commercial milk brands.
