Big bag inerting skid AzotR®

Description

Preservation of products stored in big bags by nitrogen inerting

AzotR® big bag inerting skid with welding in place and residual oxygen level control

Preservation of the product by nitrogen inerting, welding of the big bag sleeve and verification of the residual oxygen level.

The AzotR® big bag inerting skid is a self-contained, modular solution for packaging your products in big bags under a nitrogen atmosphere. This innovative machine evacuates a big bag, then injects nitrogen to ensure optimum protection of the products to be packaged.
What's more, it incorporates a sensor to test residual oxygen levels, guaranteeing optimum preservation. It is designed to be used in conjunction with a big bag filling station, or directly integrated onto an existing big bag station.

Key features :

Nitrogen inerting for optimum product preservation
Welding in place of the big bag cuff
Residual oxygen level control via integrated sensor
Height-adjustable, pivoting handle
Fork-liftable skid
Ergonomic control panel

Equipment advantages

- Optimal product preservation thanks to nitrogen inerting

- Extends the lifetime of packaged products

- Improves packaging safety and quality

- Stand-alone, modular system, easy to integrate into existing processes

- Easy to move and install

- Precise control of residual oxygen levels for optimum preservation

Features

Technical specification

Manufacturing materials: RAL 9006 painted steel (optional: 304L stainless steel, 316L stainless steel, HDPE)
Installed power: 2.2 kW 50Hz
Flow rate: 100m³/h.
Vacuum pump technology: lubricated vane pump
Absolute final pressure: 60 mbar
Dimensions (L x W x H) : to be determined according to the characteristics of your big bags

Operating principle:

The operator extends the jib and adjusts the height to suit the size of the big bag. The big bag is then positioned on a pallet in line with the welding system, and its cuff is threaded around the forming mould.
Once the big bag is correctly positioned, the operator starts the inerting, welding and residual oxygen level control cycle from the control panel.

The inerting tube is lowered, and the vacuum pump starts, enabling the vacuum preset on the console to be reached. The nitrogen injection solenoid valve is opened and the big bag is inflated with nitrogen to the preset pressure.
The big bag cuff is then welded using welding electrodes. During this process, the integrated sensor measures the residual oxygen level inside the big bag to ensure optimum product preservation.

Once the cycle is complete, the cuff closing jaws open and the big bag can be removed.

Accessories and options:

- Protective filter for vacuum pump
- Check valve for vacuum pump
- PLC (Siemens S7-1200)
- Electrical cabinet in painted steel, 304L stainless steel or polyester
- Residual oxygen level sensor for precise control and optimum product preservation

The AzotR® big bag inerting skid, with in-place welding and residual oxygen level monitoring, is the ideal solution for guaranteeing optimum preservation of your big bag products. Thanks to this innovation, you can ensure the quality and safety of your products, while extending their shelf life.
