Automatic Plastic Bottle RFC Isobaric Carbonated Beverage Filling Machine

Product overview

PET bottles used for carbonated beverages require controlled handling throughout the bottling process. The container is lighter and more flexible than glass, while the beverage itself must remain under controlled pressure to reduce unnecessary foaming and carbonation loss.

The Automatic Plastic Bottle RFC Isobaric Carbonated Beverage Filling Machine addresses both requirements within one synchronized production system.

Technogen Enterprise is an Automatic Plastic Bottle RFC Isobaric Carbonated Beverage Filling Machine Manufacturer and Supplier for Tanzania, serving Carbonated Soft Drink, Soda, Sparkling Beverage, Energy Drink, Tonic Water and Mixer Beverage manufacturers.

The machine combines Rinsing, Isobaric Counter-Pressure Filling and Plastic Screw Capping within one fully automatic monoblock.

It is designed for compatible PET or plastic bottles from approximately 100 ml to 1000 ml.

The packaging cycle begins in the rinsing turret.

PET bottles are handled through their necks, reducing unnecessary body contact during rotary transfer.

Each container is inverted for internal rinsing.

Stainless Steel spray nozzles apply the selected rinsing medium.

After cleaning, bottles drain before being returned to their transfer orientation.

The No Bottle–No Rinse arrangement prevents the rinsing system from operating at an empty station.

After bottle preparation, synchronized star wheels transfer the containers to the filling turret.

The filling system operates using isobaric counter-pressure technology.

Each PET bottle is raised and sealed beneath an ULTRA Mechanical 2-Step filling valve.

Internal air is reduced during the pre-evacuation process.

CO₂ is introduced into the bottle until its internal pressure approaches the pressure inside the product bowl.

Once equalized, the carbonated beverage flows into the bottle under controlled conditions.

This controlled pressure sequence reduces unnecessary turbulence and excessive foam generation during filling.

As the required liquid level is reached, excess pressure is released in a controlled manner.

Filled bottles are then transferred to the capping section.

Unlike the glass-bottle RFC version, this machine uses Plastic Screw Capping.

Plastic caps are supplied through an automatic feeding arrangement and chute.

Rotary capping heads apply the closure onto each bottle.

Magnetic torque adjustment controls the screw-capping operation.

PET bottles are stabilized during capping to reduce uncontrolled rotation while torque is applied.

The No Bottle–No Cap function prevents a cap from being applied when no bottle is present at the capping position. Pasted text(3)

The machine uses Stainless Steel construction with SS 304 / SS 316L materials in the appropriate sections.

Automated production functions are controlled through PLC and HMI.

The control platform provides operating settings and production information to the machine operator.

Guarded enclosures protect the rotary and mechanical operating areas.

Safety features include guard interlocks, sensors and emergency-stop controls.

Several machine configurations are available depending on the required output.

Rinsing and filling head options include 12, 18, 24 and 32 heads.

Plastic screw-capping options include 6, 8 and 10 heads.

The available output range is approximately 3,000 to 12,000 bottles per hour depending upon the selected configuration.

CO₂ pressure is specified at approximately 0.2–0.3 MPa.

Rinse pressure is approximately 0.4–0.6 MPa.

Electrical supply is 415 V, 3 Phase, 50/60 Hz. 

The Automatic Plastic Bottle RFC Isobaric Carbonated Beverage Filling Machine is particularly useful for Tanzania beverage manufacturers who want rinsing, pressure-controlled filling and cap application integrated within a single production system.

The machine can be used for compatible carbonated soft drinks, PET-bottled soda, flavored sparkling beverages, carbonated energy drinks, tonic water and mixer beverages.

Contract bottlers can also select a machine configuration according to required bottle sizes and hourly capacity.

Production-line selection should take account of bottle drawings, cap dimensions, beverage characteristics and required output.

The maximum capacity of 12,000 bottles per hour is linked to the appropriate machine configuration and should not be treated as the standard output of every version.

For smaller Tanzania bottling projects, a lower head configuration can provide the required production rate without unnecessarily increasing equipment capacity.

For larger operations, higher head-count versions increase throughput while retaining the same integrated RFC process.

Once bottles leave the machine, they can proceed to suitable sleeve labeling, sticker labeling, inspection, coding or secondary packaging equipment according to the complete beverage-line arrangement.

Working principle

• Empty PET bottles enter the rinsing turret.
• The neck-handling system secures each bottle.
• The container is inverted and internally rinsed.
• After rinsing, the bottle drains and returns to the normal transfer position.
• The No Bottle–No Rinse system prevents operation at an empty rinsing station.
• A synchronized starwheel transfers the bottle towards the filling turret.
• The bottle is lifted and sealed beneath the isobaric filling valve.
• Internal air is reduced through the pre-evacuation stage.
• CO₂ is introduced to establish the required bottle pressure.
• Bottle pressure and product-bowl pressure are equalized.
• The carbonated beverage then flows through the filling valve into the bottle.
• Controlled product flow minimizes unnecessary turbulence.
• Once the required filling level is achieved, excess pressure is released through controlled venting.
• The filled bottle moves to the rotary plastic screw-capping section.
• The automatic cap feeder delivers closures through the cap chute.
• A capping head places the closure onto the bottle.
• Magnetic torque control regulates the screw-capping action.
• The No Bottle–No Cap function prevents closure application at an empty station.
• The capped PET bottle exits the monoblock and proceeds towards downstream packaging equipment.
