De Palletizing

H.G. Molenaar has been supplying de-palletizers to both the local and international food and beverage industries since 1954.

Conventional de-palletizer model 430

Glass bottles, glass jars, food or beverage cans are fed into a production line with a de-palletizer. The containers on pallets enter the de-palletizer hoist on heavy duty pallet roller conveyors. A four-point hoist ensures stable lifting of the container stack to ensure that the top layer of containers are perfectly aligned with the take off accumulation conveyor.


A robust layer clamping and sweeping mechanism transfers the top layer onto an Intralox accumulation belt. From the accumulation conveyor the containers are conveyed in mass or single filed into the production line.


Once the complete stack has been de-palletized, the empty pallet exits the machine on roller conveyors. Depending on the de-palletizing speed required, an automatic layer pad remover and empty pallet stacker can be added.

Robotic de-palletizing:

H.G. Molenaar also uses the latest robotic de-palletizing technology. The versatility of the 4-axis robot arms, in combination with highly effective gripper heads, provides for a low maintenance solution for de-palletizing.

Depending on the speed requirement, the gripper head can, in addition to transferring the container layer, also be used to transfer the layerpad and empty pallet. In other words it can replace the automatic layerpad transfer mechanism and the empty pallet de stacker.

The advantages of the H.G. Molenaar de-palletizer:

  • Robust construction
  • Low maintenance
  • Customized layouts
  • State of the art control systems.

Molenaar Magnetic De-Palletizer Model 410:

A magnetic de-palletizer PDP model 410 is utilized for de-palletizing full metal cans or glass jars with metal lids. The layer to be de-palletized is transferred from the pallet stack to an accumulation conveyor by means of a permanent magnet with stripper plate. From there the containers are single filed to be transferred typically to a labeller. Several customized layouts are possible with addition of automatic pallet conveyors, platforms etc.


PET bottles are fed into a packaging line with an unscrambler and not a de-palletizer. The hopper on the unscrambler is fed with bottles by means of a full pallet tipper.

Pace unscramblers

Unscramblers are used when empty plastic containers have to be handled in such a way that they are presented to the filler in a uniform manner. This is especially necessary when Petaloid containers, which are very unstable when empty due to their light weight and base design, are used.

pace-logoPace Packaging Corporation from the USA offers an established range of linear unscramblers to handle plastic containers. They are universally-suited for all packaging industries, most notably in: beverage, dairy, water, juice, food, household products, personal care, pharmaceutical and lubrication products.


Molenaar S-Type and C-Type Gripper belt rinsers

The next step in a packaging line normally involves the rinsing of the container. H.G. Molenaar can provide a range of in line rinsers for cans and bottles. The S-Type Lowerator/rinser provides a dual function by transferring containers from high level (typically from a de-palletizer high level discharge) down to the height of a packaging line. Air or water rinsing is possible.

packaging06 packaging07

A C-Type rinser has all the same functions of the S-type, but containers enter and exit on the same level.

The advantages of the H.G. Molenaar S and C Type rinsers:

  • No change parts needed
  • Gentle handling of all container types
  • No friction around turns on high speed models.

For low speed rinsing requirements we can offer an inverter and reverter block with straight rods in between. A pressure drive will push the containers through the two blocks. Rinsing will take place in the section between the inverter and reverter. This rinser can be used with warm water spray to heat up glass jars prior to hot filling.


After rinsing, containers are transported to a filler. Depending on the product and container type, H.G. Molenaar can provide:

Molenaar Volumetric Pocket Fillers

A Molenaar volumetric pocket filler is ideal for any dry product such as corn, beans, peas, shredded vegetables or fruit pieces. It has been hygienically designed for low and high speed applications and change parts in the form of inserts for the pockets can be used for different volume filling such as filling cans or jars.

Advantages include:

  • Accurate head space, net weights and high vacuum
  • Low maintenance due to simplistic design
  • Low liquid loss
  • Suitable for can sizes from 8Oz to A10
  • Direct coupled with seamer.

Piston Filler from Elmar

A piston filler is very well suited for canning or bottling high viscosity products.
