Milk Bottle Filling and Sealing Machine Line Price

Q1  What types of dairy products can this machine fill — fresh milk, UHT milk, yogurt, or flavored milk?

Milk filling machine can fill fresh milk, UHT milk, yogurt, and flavored milk.

Q2  What filling technology do you use for dairy — gravity, piston, or flow meter? What is the accuracy?

For dairy,the choice depends on the product viscosity:

Gravity Filling:Best for thin dairy (milk,kefir). Accuracy is typically ±1%.

Piston Filling: Best for thick dairy (yogurt, shakes). High accuracy of ±0.5% to 0.1%.

Flow Meter Filling:Best for liquid dairy (flavored milk). Accuracy is high at ±0.5%.

Q3  What hygiene standard does the dairy filling machine meet — food-grade SUS316L or SUS304 stainless steel?

The dairy filling machine typically meets food-grade SUS304 as the standard, with SUS316L available for high-corrosion or high-temperature dairy applications (e.g., acidic or salty products).

Q4  Does the machine support hot filling for UHT milk as well as cold filling for fresh milk?

Yes, the machine supports both. Use aseptic filling for UHT milk (hot fill/room temp) and cold filling for fresh milk (refrigerated).

Q5  What container types are supported — plastic bottle (PE/PET), glass bottle, or gable-top carton?

Plastic bottle(PE/PET), glass bottle and gable-top carton all can be filled use corresponding filling machine. Not work in same machine.

Q6  How does the CIP (Clean-In-Place) system work on your dairy filling machine?

The CIP system on our dairy filling machine automatically circulates water, cleaning agents, and sanitizers through the filling lines and contact surfaces without disassembly. It removes milk residues, fats, and bacteria, ensuring hygiene and compliance with food safety standards. The process is fully programmable, time- and temperature-controlled, and uses minimal manual labor.

Q7  What is the production speed for a standard 1-liter milk bottle?

The production speed for a standard 1-liter milk bottle typically ranges from 2,000 to 24,000 bottles per hour on standard industrial filling lines .

Q8  Can the machine handle dairy products with different viscosities — thin fresh milk vs. thick yogurt?

Yes, the machine can handle both thin fresh milk and thick yogurt, provided it has adjustable viscosity settings or a compatible pump/valve system.

Q9  How do you prevent foaming during milk filling, which can cause underfill or contamination?

To prevent foaming during milk filling:  

1. Use slow bottom-up filling or laminar flow nozzles to minimize turbulence.  

2. Maintain proper milk temperature (2–4°C) and avoid excessive agitation.  

3. Install antifoam devices (e.g., foam breakers or ultrasonic sensors).  

4. Ensure clean, dry filling equipment to prevent bacterial foam formation.  

5. Reduce filling speed and use vacuum-assisted filling when applicable.

Q10  What certifications does your dairy filling machine carry (CE, ISO 9001, food safety, etc.)?

Our dairy filling machines carry CE certification. We also comply with hygienic design standards for food safety. For specific requests regarding ISO 9001 or other documentation, please contact us directly.
