bulk product palamatic process

Big bag and bag unpacking station - Suction tube - Multi-product vacuum emptying

Flow rate: 50 kg to 2 tons/hour

Manufacturing: steel, 304L stainless steel, 316L stainless steel

For partial discharging, multi-products & integrated weighing

System of automatic big bags and drums unloading through a retractable suction tube that vacuums the bulk material. This station, from the EasyFlow® range, offers you the possibility of partially or totally emptying your big bag to make multi-product recipes. Integrated weighing makes it possible to precisely control and manage the amount of product to be vacuumed

The EasyFlow® Flex big bag unloading station has been designed by Palamatic Process to purge the desired quantity of materials precisely (via a weighing system) by vacuum. The possibility of evacuating a semi-unloaded big bag is the main objective of this machine. With EasyFlow® Flex, a single station is sufficient for multi-product discharging. It is the combination of a VFlow® conveying system and a big bag station. This station allows automatic unloading operations without operator intervention. Big bags are positioned using a simple pallet truck or forklift..

Operating principle:

  • The big bag is positioned on the station using a pallet truck. The operator connects the mouth of the big bag
  • The telescopic tube, connected to the pneumatic conveyor by suction, plunges into the big bag
  • A big bag massage device, coupled with a ventilation system, allows a refocusing of the product for a total emptying of the big bag
  • The big bag lifting system has a dual purpose:
    • 1) ensure weighing without interference;
    • 2) optimize the flow of the product
  • Reclosing of the empty or semi-empty big bag
  • Rate

Technical specification

Flow rate 50 kg to 4 t./h
Manufacturing materials Painted steel, 316L stainless steel
Installed power 1 to 8 kW

Dosage accuracy: 500 grams (may vary depending on the density of the product)

Equipment integrated into the EasyFlow® Flex model:

- Telescopic suction tube: the suction tube plunges into the centre of the big bag. Its descent is controlled continuously or controlled by the level sensor fixed at the end of the tube and which detects the "product lack".
- Inflatable seal: the chute of the big bag is connected to an inflatable seal to seal the assembly.
- Blowing fan: the big bag blowing fan ensures a constant shaping of the big bag in order to facilitate the complete emptying of the big bag (no folds)- Control cabinet: the cabinet allows to control the quantity of suctioned product
