Emptying bags, Big Bags, drums and containers

For emptying bags, we have developed the DIMA® series. This series consists of manual, semi-automatic and fully automatic versions of the DIMA® bag emptying machine. Depending on the product to be processed, there are various options. A pneumatic cleaning system can be used, which can be equipped with a special dust-free sealing of the air outlet.

To empty Big Bags, Dinnissen has designed a Modular Big Bag Unloading Station. As the name suggests, the station can be built based on specific customer needs. The Big Bag Unloading System is suitable for easily flowing materials as well as poorly flowing products. Besides bags, drums and containers are a frequently used means of transporting powders, grains and granules. Dinnissen develops customized solutions for both toxic and non-toxic materials.

Big Bag Conditioner

Due to agglomerated product, emptying Big Bags can be a time-consuming occupation. Clumping can be a product characteristic but can also be caused by dampness or compression during transport. By combining the conditioning and discharge of Big Bags in one solution, Dinnissen's Big Bag Conditioner ensures that Big Bags can be emptied effortlessly and quickly. The Big Bag Conditioner is designed, built, and tested in-house, guaranteeing you the highest quality.

  • Conditioning, emptying and discharging in one station
  • High discharge rates
  • Validated system

The DIMA® Bag Emptying System is an innovation that makes emptying bags even more efficient, safe and operator-friendly. For low capacity and maximum flexibility, the DIMA® MAN is a good choice. This system allows the bags to be emptied manually. The operator cuts open the bag and empties it into the intended chute. The semi-automatic DIMA® Bag Emptying System takes away one action from the operator, by automatically cutting open the bags. For the most critical applications or toxic products, bags can be emptied and discharged fully automatically. The focus is on fast and long-lasting emptying of bags under extreme conditions, with a DIMA® that suits the product to be processed and the desired capacity.

  • Robust quality making DIMA® Bag Emptying Systems last for years
  • Based on proven techniques and decades of experience
  • Extremely safe way of emptying bags efficiently

When emptying Big Bags, safety comes first. It’s important for the operator to limit dust to a minimum and to keep the Big Bags from falling over, under any circumstances. The Modular Big Bag Unloading Station is used for the safe and dust-free unloading of Big Bags containing various materials. After a Big Bag has been hung in the right place with a forklift or hoisting system, the bottom of the Big Bag is attached to a filling pipe. The Big Bag Unloading Station is suitable for both easily flowing materials and poorly flowing products and, due to its modular design, can be used for both harmless and toxic products.

  • A safe and ergonomic design
  • Suitable for poorly running products as well
  • Designed to meet the most stringent safety requirements

Drum and Container Handling

Available on request

Whatever the size of the barrels or containers to be emptied and whatever their contents: Dinnissen will help you find the best possible solution. For non-toxic substances, (part of) the process can be carried out manually. For example, the operator can open the drum manually (by using a glove box, if desired) and then turn the drum with a tipper to empty it. For toxic or explosive substances, it is crucial to ensure the operator is not exposed to particulate matter. In such cases, drums and containers are hermetically connected to a product discharge before being turned and opened.

  • Customized solutions for both toxic and non-toxic substances
  • Designed, developed, and tested in-house
  • Safe working environment without particulate matter
