Supplier of Pet Filling Machine or Pet Bottling Machine

PET Bottle Filling Machine Overview

This PET bottle filling machine combines rinsing, filling and capping in one unit for suitable juice and tea beverages. Hot-fill temperature, product properties and PET bottle specifications should be confirmed for each project.
The listed output range is 5,000–24,000 bottles/hour; the achievable rate depends on bottle size, beverage properties and the selected configuration. The filling and product-return systems should be specified for the intended beverage and process. For the complete upstream process, see our fruit juice production line.

The referenced configuration is described for hot filling below 95°C; the final filling temperature must be set for the product and bottle. The filling valve and product pipelines are designed for cleaning, and the described configuration includes CIP connections and an RO-water bottle-mouth rinse before capping. It adopts a magnetic torque type capping head to realize the function of grabbing and capping. The whole machine adopts touchscreen control, PLC computer program control, inverter control, and other advanced technologies. Depending on the control configuration, functions can include filling-temperature monitoring, alarms, automatic reflow, missing-bottle detection and a stop when caps are unavailable.

The rinsing, filling and capping unit is intended for compatible fruit juice and tea beverages in heat-resistant PET bottles. Bottle, cap and product suitability should be confirmed against the selected filling process. This machine is made of high-quality SUS304 material, the key components are precision processed by CNC machine tools, and the whole machine adopts advanced photoelectric to detect the operation status of each component.

PET Bottle Filling Machine Performance

The bottle feeding adopts an air-conveying device, which is fast and will not deform the bottle.
The bottle mouth flusher adopts advanced block bottleneck technology to avoid contact with the threaded mouth, which is more hygienic. The bottles are conveyed using block bottleneck technology, so there is no need to adjust the height when changing the shape of the bottle. The filling unit uses a lifting-valve arrangement; the required filling principle should be confirmed for the product and final machine configuration.
The cap sorting device is installed at a low level and fed horizontally.
PET bottle three-in-one filling machine integrates rinsing, filling, and capping, and is developed according to the filling process requirements of juice and other beverages. The referenced juice process lists a filling temperature around 82–85°C; the final setpoint depends on the beverage and container.

PET Bottle Filling Machine Technical Details

Bottle Rinsing

This machine is mainly used for rinsing new bottles of juice. The bottles are then sent to the filling machine for juice filling.

The PET bottle enters the machine by the star wheel and the clamp clamps the bottle mouth and turns it to the bottle mouth facing down. The bottles are rinsed with sterile water, drained, automatically flipped upwards, and transported to the filler through the star wheel.

The main structure and external protective cover of the equipment are made of high-quality stainless steel.

Brand new stainless steel clamp, simple structure, easy to adjust. It has less contact area with the bottle mouth, which effectively avoids secondary pollution of the bottle mouth.

The bottle rinser is equipped with a water tray to recycle the rinsing water.

Juice Filling

The filling part is to fill the material into the washed bottle sent by the bottle rinser. The filling valve and pressure arrangement are specified for the selected beverage and process. There is no spring in the valve, and the juice does not contact the spring, which is conducive to cleaning inside the valve.

The filling cylinder adopts a full cylinder to ensure pressure stability in the cylinder.

The whole machine has a perfect CIP cleaning interface.

The machine adopts PLC automatic control, and the fault is displayed online, such as bottle blockage, missing cap, etc.

Bottle Capping

The capping part is to screw the cap onto the bottle that has been filled with juice and send it to the back process by the conveyor chain.

The cap screwing machine drives the turntable to rotate through the reducer. Make the lid exit the hopper from the lid outlet under the action of centrifugal force. The cap is screwed by magnetic force, which has the function of overload protection, and the capping torque is stable and reliable.
