DESCRIPTION

 

Project objectives:

  • Development of a plant and process technology for the production of pet food with due regard to the addition of freeze-dried vegetables.
  • Optimization of sanitary regulations: utmost hygienic design of the plant, using a very smooth surface.
  • Traceability of each component - in case a claim is registered, it can be detected which product was added during which time.
  • Improvement of the plant's operational efficiency

  • Quality improvement of the ready-made pet food

  • Easy maintenance due to big cleaning lids;  mainentance of the plant can performed without the use of any tools

 

Process technology

The freeze-dried vegetables are manually loaded, fully automated dosed and fed to the wet mixers, in which the ready-made mixture of the product is produced.

 

Each raw material is loaded into the corresponding receiver bin in an unmixed condition. Below the receiver bin high-precision loss-in-weight-feeders are positioned, which enable an accurancy in the gram range. These dosing units are equipped with a vibratory feeder which allow a very gently handling of the ingredients. Subsquently the product is transfered to the cyclone separators through pneumatic conveying lines. A side channel blower generates the conveying air, whereby the noise is reduced by a noise dampener.

 

The implemented aspiration system ensures, that dust emissions are not generated by suctioning the dust while filling the containers. In the context of the occupational health and safety minimal MAC-values (maximum allowable concentration) can be achieved.

 

Innovative transfer system

A very special innovation of the pneumatic transfer system is the newly developed Daxner-injector system. This conveying system ensures the gentle intake and transfer of very fragile products. In the final stage of the transfer distance special cyclone separators are positioned, which were developed and optimized in various test series. These trials were performed with all products at Daxner's headquaters. Also of significant importance is, that the implemented injector transfer substituted the conventional used dosing units (rotary valve).
