Description

AUTOMATIC BAG DUMP STATION - VARISLIT® - For high speed deconditioning, multi bags from 15 to 50 kg without adjustments

Automatic bag dump station with double-blade rotating system for processing large bags with an extremely high emptying rate without dust emission into the atmosphere. 

The Varislit® bag opener is widely used in the food, pharmaceutical, chemical and agrochemical industries. Its patented inversion system conveys empty bags in a screw compactor, which is an integral part of the system. The dust extraction option offers the best solution for fast, dust-free automatic opening. The double-blade rotary system, which is standard on this machine, and its elongated shape allow to handle large bags with an extremely high emptying rate. The entire mechanics are placed outside to avoid contact with the material (bulk, powder...).
This machine is designed to open 12 bags/min.

Operating mode

1. The operator positions the bag with a bag manipulator on the belt conveyor that supplies the bag dump station

2. The bag is detected by the sensor controlling the cutting system

3. The blade cuts the bag and the lower part is grasped by the inversion discs

4. When the sensor is deactivated, the blade returns to the rest position so as not to cut the bag in half

5. The bag is then directed to the bag compactors and the machine is ready to receive the following bag

Options

Available options

  • Automatic sack discharging - Bulk material and powder handling
    Automatic sack discharging - Bulk material and powder handling

    Bag manipulator

    Sack manipulator : The operator, via a simple control handle, depalletizes the bags and positions them on the infeed conveyor.

    The infeed speed is ensured with maximum ergonomics.

  • Automatic sack discharging - Bulk material and powder handling
    Automatic sack discharging - Bulk material and powder handling

    Rotative cleaning nozzles/heads - Clean In Place (CIP).

    The installation of nozzles inside the machine allows to ensure a complete and automatic cleaning of all the equipment after the opening phase.

    Several nozzles are installed to clean the entire machine and thus ensure zero cross contamination.

    The drying phase using filtered hot air (H14) is also offered by the Palamatic Process design office.

  • Automatic sack discharging belt conveyor - Bulk material and powder handling
    Automatic sack discharging belt conveyor - Bulk material and powder handling

    Infeed belt conveyor

    The belt conveyor is used to deport the operator from the entrance of the machine.

    The belt conveyor is either vertical or inclined. Its design incorporates sensor cells that can also control the flow of the machine.

    The lengths are defined according to the installation constraints.

    A gooseneck is provided for inclined conveyors.

    Dust collection

    Dust removal is the essential additional equipment to ensure a healthy working atmosphere.

    The dust collector is installed directly on the machine and thus makes it possible to reintroduce the vacuum fines or is positioned outside for independent dust collectors.

    • Dust removal rate required: 1,000 m³/h.
    • Filtration technology: cartridge or pouch
    • Unclogging: compressed air
    • Filter medium (variable according to the type of powders): antistatic polyester, oleophobic, PTFE coated...
