Filling-capping machine for flexible pouches TEF 250

The machine is air-driven and is designed for filling and capping flexible pouches (those with an existing spout) containing liquid or semi-liquid products. It utilizes a volumetric piston filler with a dosing range of 50-1300 ml, and seals the pouches with plastic screw caps of the same size.

All components in contact with the product are manufactured out of AISI 316 L stainless steel and food grade gaskets. The cap is tightened by a pneumatic motor with torque regulation.

This unit can fill viscous products containing soft particulates or fibers and is suitable for hot filling (100°C).

Technical features

Production: maximum production up to 500 pieces/hour of 90 ml volume pouches, depending on the operators speed.

The main frame of the machine is made out of stainless steel AISI 304, and is mounted on wheels. All equipment components that come in contact with the product, including the shaft, are made out of stainless steel AISI 304. The filling & capping machine has a manual pouch positioning. 

Single head capping:

• Air consumption is around 250 Nl/min.
• Requirements: air compressed 2÷6 bar.

Filling unit consists of:

Volumetric dosing unit from 50 to 1300 ml, AISI 316 L stainless steel

• Food grade set of gaskets
• Three way rotary valve
• Pneumatic two way no drop valve with a switch off nozzle
• Food grade flexible hose
• Hose tail that connects the unit to the storage tank

Single head capping unit consists of:

• Pneumatic motor
• Stainless steel chuck for one size of plastic screw cap
• Manual control for adjusting the height of the equipment
• Nitrogen injection unit

HOW IT WORKS

The machine operator places the pouch on the collar and, using a hand-wheel control, adjusts the filler to regulate the product filling capacity. Both filling speed and suction can be finely tuned to meet highly specific requirements. Upon manually moving the lever, the filling valve starts operating, and the employee initiates the filling process with a button press.

As the filling process nears completion, the machine injects nitrogen into the empty space of the pouch. This step expands and preserves the product, effectively extending its shelf life. The injection time and flow of nitrogen can be precisely adjusted using the pressure regulator. Following this, the employee places the cap on the spout, positions the closing head in the capping position through the lever mechanism, and manages the cap tightening process to ensure proper sealing.
