The coating of pet food croquettes is an important phase of the process, as the external covering of a croquette is the initial contact with the animal as well as the main point of reference that the customer will trust.

 

The coating phase must be carried out to:

  • Obtain color homogeneity in all croquettes
  • Reduce oil loss and greasy look and feel
  • Improve the distribution and homogeneity of palatant and flavoring additives.
  • Reduce disinfection problems in the coating process

 

CONTINUOUS COATING BENEFITS

Pro: High-level of homogeneity (CV) can be obtained even with the addition of low amounts, being more flexible and kind with the production and the product itself.

 

Requirements for a successful application:

 

  1. Performing croquettes dosing: The dosage must be carried out using continuous gravimetric weighing systems, not volumetric. The variation of the incoming product flow must be adjusted and stabilized by the proportioner to have a uniform output.
  2. Covering: The team must be as gentle as possible with the product but should also guarantee good mixing homogeneity. The retention time is essential when high amounts of oils are added, and should not be less than 60 seconds.
  3. Atomization: Continuous atomization is a real challenge, especially when the product flow varies. Standard nozzles are always exposed to dirt and blockages. PLP recommends SMOG Technology for perfect atomization in any condition and viscosity.

In addition to the points mentioned above, there is another very important factor during the coating process, which will result in a more homogeneous final product:

 

HOLDING TIME

Homogeneity is also related to the absorption of fat by croquettes. As for the process, this can be increased thanks to the combination of heat and croquette retention in the mixing phase in the covering.

 

The MT series is equipped with heating chambers that maintain a controlled temperature inside the machine, while the retention time is increased by:

 

RETENTION GATE

PLP has developed an automatic check gate, located at the outlet of the machine.

It is suitable for stopping the croquette flow and releasing it when product accumulation reaches a certain level inside the machine.

Thus, it significantly increases the retention time, up to 180 seconds inside the MT machine.
