Z1 Optifreeze™

The facilitator for sorted stacks of frozen goods in onboard palletizing. Z1 gathers frozen products (any given number of different cartons / bags with agreed size), and temporarily store them in a shelf system inside a freezing room (hotel). When an equivalent of a full pallet of a product is stored in the shelves, it goes out from the Z1 and further to palletizing.

As they are entering the system, a hatch opens and a XY-axed servodriven elevator unit will pick up the product and run it to a suitable spot for temporary storing. Next and in between the XY-elevators may provide finished sortings for palletizing, as soon as there is enough for a full pallet. It can run infeed simultaneously with direct palletizing ongoing in parallel, so that all goods types except one goes to the hotel. This gives a total factory palletizing capacity higher than that of the hotel receive rate. At all time you have a full overview via HMI screens of the present contents in the hotel, and you can make signal whenever you want to run a new pallet and of which sort you want. You can create specific mixed pallets based on your requested setup.

Capacity depends on the following factors: Length and height of freezing room, number of products on shelf, and number of infeed. Example: Room: 8m length, 2,95m height, 4 master cartons on shelf and 1 infeed:

  • Receive rate: >=2 cartons per. minute. 
  • Deliver rate: >= 8 cartons per. minute.

Higher capacity rates are available with the Optimar Z2 hotel system.
