In the juice industry, the transition from raw fruit to a shelf-stable bottled product is race against oxidation and microbial spoilage. A high-efficiency juice factory machine lineup must do more than just fill bottles; it must preserve the vitamins, color, and natural flavor of the fruit while ensuring a shelf life of up to 12 months without preservatives.
At Chenyu Machinery, we provide complete juice production line solutions that focus on three technical pillars: thermal stability, biological safety, and operational flexibility.
UHT Sterilization & Blending System:
The journey starts in the processing room. Before filling, the juice must undergo UHT (Ultra-High Temperature) sterilization. Our systems heat the juice to 135-140℃ for a few seconds and then rapidly cool it to the target filling temperature. This precise thermal curve kills heat-resistant bacteria while minimizing the “cooked” taste often associated with lower-quality processing.
3-in-1 Juice Filling Machine:
For most juice products, Hot Filling (at 85-92 ℃) is the gold standard.
- Heat Resistance: Our filling valves are crafted from SUS316L stainless steel, designed to withstand constant high temperatures without deformation.
- Recirculation System: If the juice filling line stops, the juice is automatically recirculated back to the sterilization unit to prevent it from cooling down in the pipes, which would risk microbial growth.
Vacuum Suction and Headspace Control
To prevent oxidation (which turns juice brown), our juice filing machines utilize vacuum suction system during the filling process to remove air from the bottle headspace. Immediately after capping, the bottles pass through a Bottle Tilting Sterilizer, which uses the hot juice itself to sterilize the inside of the cap.
Cooling Tunnel and End-of-Line Automation
Hot-filled juice must be cooled quickly to preserve its nutritional profile. Our spray cooling tunnels use graduated temperature zones to bring the juice down to room temperature gently, preventing “thermal shock” that could deform PET bottles. From there, the bottles move to high-speed labeling and shrink-wrap packaging.
FAQ:
Q1: Can your juice factory machines handle juice with pulp or fruit pieces?
A: Yes. We offer specialized large-passage filling valves designed specifically for juices containing pulps or fibers (up to 5mm x 5mm pieces) without clogging or damaging the fruit texture.
Q2: How do I ensure the juice doesn’t change color or taste after bottling?
A: This is achieved through three methods:
1. Minimizing Dissolved Oxygen (DO) via vacuum filling.
2. Rapid cooling after hot filling.
3. Using UV-blocking additives in your PET bottle production.
Q3: What kind of cleaning (CIP) is required for juice filling line?
A: Juice lines require rigorous cleaning due to sugar content. Our machines are fully integrated with 3-stage CIP systems (Hot water, Acid, and Alkali wash). The PLC manages the cleaning cycles to ensure every valve and pipe is 100% sterile before the next production run.
