The Aseptic & Ultra-Clean Advantage
Our automatic milk filling machines and coffee filling machines are built on a foundation of advanced aseptic and ultra-clean filling principles. This is not just filling; it’s a systematic approach to contamination prevention.
Aseptic Filling, Done Clean and Right
Filling with full jet without contact ：The product is delivered by flow without the valve contacting the bottle mouth, thus the risk of contamination is minimized and cleanability is maintained.
Neck Handling and Load Cell Precision ：Fill weight is precisely controlled by high precision load cells. To ensure that quality and compliance requirements are consistently met, bottles are gripped by the neck for stable and consistent filling.
Dual-speed low-foam filling Fast filling comprises the bulk of the fill, then slows for an accurate top-off. This ensures filling accuracy and reduces foaming. A secondary diaphragm guarantees gentle valve closing to protect product quality.
Hygienic Product Feed & SIP Sterilization ：The product is delivered from above via a sealed manifold. All critical product paths are sterilized with pure steam (SIP) which establishes a fully sterile zone for filling aseptically with confidence.
Filling Systems Made for Milk & Coffee
Selecting the right technology is key to your product’s success. The choice depends heavily on your target shelf life and distribution channel.
| Filling System | Hot Fill | Ultra-Clean (UHT +) | Aseptic |
|---|---|---|---|
| Process | Product heated to ~85-95°C, filled hot into containers, cooling creates vacuum seal. | Product is UHT sterilized and filled in a high-hygiene, positive-pressure clean room. | Product and packaging are sterilized separately, then filled and sealed in a sterile environment. |
| Shelf Life | 6-12 months (ambient). | 30-90 days (chilled) or several months (ambient with robust packaging). | 9-12+ months (ambient) without refrigeration. |
| Packaging Cost | Higher. Requires heat-resistant PET/glass. | Moderate. | Higher (sterile packaging). |
| Ideal For | High-acid juices, teas, some flavoured milk & coffee drinks. | Fresh milk, ESL (Extended Shelf Life) dairy, cold brew coffee. | UHT milk, plant-based drinks, RTD coffee for global distribution. |
| Our Machine Fit | Standard models with heated tanks & vales. | Models with HEPA enclosures & strict environmental controls. | Full aseptic filling machines with sterile zones, steam sterilization, and aseptic cappers. |
Milk vs. Coffee Production: A Process Comparison
Understanding the unique and shared stages of production highlights why specialized filling technology is essential.
| Production Stage | Milk Processing | RTD Coffee Processing | Implication for Filling Machine |
|---|---|---|---|
| 1. Raw Material | Raw milk (fat, protein). | Coffee beans, extracts, water, sweeteners, dairy/alternatives. | Machine must handle varying viscosities and compositions. |
| 2. Standardization | Fat content adjusted (whole, skim). | Recipe mixing: coffee strength, sweetness, milk ratio. | Precise volumetric or mass filling is critical for recipe consistency. |
| 3. Homogenization | Critical. Breaks down fat globules. | Required only if containing milk/creamer. | Filling must be non-turbulent to maintain emulsion stability. |
| 4. Sterilization | Pasteurization (fresh) or UHT (ambient). | UHT is standard for ambient RTD coffee. | Aseptic filling machine is mandatory for UHT products. |
| 5. Cooling / Buffer | Cooled post-pasteurization; UHT held in aseptic tank. | UHT coffee held in aseptic tank. | Machine must connect to aseptic buffer tanks without breaking sterility. |
| 6. Packaging Format | PET bottles, glass bottles, pouches, cartons, cans. | PET bottles, cans, glass bottles. | Our lines are versatile for milk pouch filling machine and milk bottle filling machine setups. |
| 7. Filling Environment | Clean (pasteurized) or Sterile (UHT). | Sterile (UHT). | Requires ISO 14644 cleanroom standards for aseptic filling. |

we’re here to all your questions
Can one machine handle both milk and coffee?
Yes. The aseptic filling core is the same; differences lie in upstream processing and cleaning. Our lines are designed for multi-product use with effective CIP for both dairy and coffee.
Small milk filling machine vs. aseptic machine?
Small milk machines are usually low-speed systems for fresh, chilled milk. Aseptic machines are fully automated, sterile systems for ambient, long shelf-life products. We offer both.
Is aseptic filling needed for cold brew coffee?
Chilled cold brew (30–60 days) typically uses ultra-clean filling. Ambient-stable cold brew (6–12 months) requires full aseptic filling.
What packaging formats are supported?
Bottles (PET, glass, HDPE), pouches, cans, and cartons with spout filling.
How is sterility ensured?
Through steam sterilization, ISO 5 overpressure air, cap sterilization, and validated automatic CIP/SIP achieving SAL 10⁻⁶.
