Juice filling machine

Name: Juice filling machine
SKU: 0

The hot filling machine for fruit juice integrates bottle rinsing, hot filling, and capping into a single unit, making it suitable for the high-temperature filling of products such as fruit and vegetable juices and fruit-flavored beverages. Constructed from food-grade 304/316 stainless steel, the machine is designed for PET bottles, with customization options available for glass bottles. It utilizes a high-temperature hot-filling process—relying on the product's high temperature to achieve sterilization and inhibit microbial growth—thereby extending shelf life. It can be integrated with blending systems, UHT sterilization units, and downstream packaging equipment to form a complete fruit juice production line.

FAQ

Product Value

Hot-fill preservation: Combines a hot-filling process with UHT sterilization to reduce microbial load, extend shelf life, and minimize the need for preservatives.

Suitable for products with particulates or high viscosity: Features an optimized anti-clogging filling valve capable of handling clear juices as well as juices containing pulp or fruit pieces, ensuring smooth flow and preventing blockages.

Integrated, fully automated production: Combines bottle rinsing, filling, and capping into a continuous operation, reducing manual handling, boosting production capacity, and lowering labor costs.

Easy to clean and residue-free: Utilizes a fully open, detachable valve assembly that supports CIP (Clean-in-Place) procedures, minimizing sugar and pulp residue to prevent bacterial growth.

Applicability boundaries

Applicable products

Clear fruit juices, fruit-flavored beverages, juices with fine pulp, and tea beverages; hot filling at 85–92°C.

Applicable containers

Heat-resistant PET bottles; machines for glass bottles can be customized.

Required auxiliary equipment

UHT sterilizer, blending system, and air compressor; production facility must meet food hygiene standards.

Working Principle

Empty bottles are fed into the rinsing station, where their inner walls are washed with high-temperature purified water.

The bottles are conveyed to the filling station, where the hot-filling valve opens to allow high-temperature fruit juice to flow in, with the fill level controlled by a liquid level ring.

The valve closes once filling is complete.

The bottles, now filled with hot product, proceed to the capping station for cap placement and tightening

Following hot filling, the bottles undergo an inversion sterilization process to sterilize the cap and bottle mouth, after which they are cooled and conveyed to the next stage of the process.

Changeover/Cleaning/Maintenance

Changeover

1. Adjust the spacing of the infeed/outfeed screws and star wheels to match the bottle diameter.

2. Adjust the heights of the rinsing grippers, filling valves, and capping heads to match the bottle height.

3. Adjust the capping torque and verify the fit between the filling valves and bottle mouths.

4. Configure filling time and temperature parameters; run a test cycle to verify the liquid level.

Cleaning

End of daily production: Perform a full CIP (Clean-in-Place) procedure—including caustic wash, hot water rinse, and fresh water rinse—to remove fruit pulp and sugar deposits from the piping.

Routine Maintenance

Replace wear parts such as filling valve seals and gripper pads; calibrate pressure gauges and check the lubrication of drive components.

How should I handle clogging in the filling valve?



Causes include oversized fruit pulp particles, clumping due to temperature drops, or filter screen blockages. Solutions: Ensure proper upstream filtration, maintain the correct filling temperature, and regularly clean the feed filter and filling valve assembly.

How long does it take to switch bottle specifications?



If the bottle neck remains unchanged and only the height and diameter vary, a skilled operator takes 20–35 minutes.

Why does the bottle body deform or collapse after filling?



Causes include using standard (non-heat-resistant) PET bottles or an improper cooling process. Solutions: Use heat-resistant bottles specifically designed for hot filling; strictly follow the process of bottle-inversion sterilization before proceeding to spray cooling.

What are the key precautions for CIP (Clean-in-Place) cleaning?



High sugar content in juice makes it prone to scaling and fermentation. Solutions: Perform a complete CIP cycle (caustic wash followed by hot water rinse) at the end of every shift; disassemble removable filling valve parts for cleaning whenever possible; and ensure pipelines are drained of residual material during shutdowns to prevent sugar scale from hardening.
