PXBWBF – Belt Weighing Batch Filler

The machine is designed to batch frozen products into bags or cartons in fruit and vegetable industry. This is the multi-purpose machine and can also be used for other different products, non- frozen ones. The machine is suitable for operation at below zero temperatures and is made of food grade materials.

Product Description

The machine is designed to batch frozen products (post IQF)  into bags or cartons. It is typically used for bags and cartons ranging from 10-25 kg / 20-50 lbs, and can also be used on larger octobins.

This unit is typically deployed as bulk packing step, or for lines where post-IQF product is stored and staged prior to primary packaging.  High-capacity lines sometimes keep this unit as a backup if the automated filler goes down, to avoid unit down issues.

The machine is suitable for operation at below zero temperatures and is made of food grade materials, including 304 ss.


Primarily post-IQF items with an individual size maximum of 8cm / 3″.

  • Berries
    • Blueberries
    • Cherries
    • Strawberries
    • Raspberries
  • Sliced / Diced Vegetables
    • Carrots
    • Green Beans
    • Onions
    • Peas
    • Potatoes
    • Sweet Corn Kernels
    • etc.


Product, post IQF and post any lump breaker, is fed to the infeed hopper.  Any packaging to be filled is hung from (bags) or placed below. The program is set for the product and desired weight.  The weighing unit automatically checks the initial state: the intermediate hopper flap closing, packaging presence, automatic tare weight, strain gauge correct operation, etc.

The dosing process is started by pressing the start button or automatically after closing the weighing hopper flap. The control unit starts the belt conveyors (separate ). During dosing, the display shows continuously the present weight value of the product being dosed. In the last precise dosing phase only narrow conveyor works. The batch weight within the tolerance is considered as the correct dosing, which is informed with the signal light. When dosing is incorrect (batches outside the tolerance), an operator decides on what to do with a particular batch.

In the case of automatic dosing, the intermediate hopper flap is opened, packaging is filled up and disconnected from the discharge hopper.


The most important machine part is the dosing unit that consists of two belt conveyors (rough and precise one) and the weighing unit that consists of the weight processor, strain gauge, weighing hopper with the pneumatic closing/opening system and pneumatic bag holding system. To reduce a risk of the product bridging or sticking to minimum, the weighing, discharge and charging hopper are made of the decorative tread plate ensuring low adhesion to the hopper walls.
