​Production process​

A Pioneer in High Quality Organic Phosphate

PB Gelatins/PB Leiner's animal phosphate is manufactured in Vilvoorde (Belgium) and Heilongjiang (China). This is carried out using a proven process that yields a very pure dihydrate and microcrystalline dicalcium phosphate. In the first step, tricalcium phosphate is dissolved from degreased animal bones with hydrochloric acid (HCl), which results in the formation of a monocalcium phosphate solution. In the next step, the dihydrated dicalcium phosphate crystals are precipitated by adding lime milk (Ca(OH)2). After dewatering, the dicalcium phosphate is then dried up to final specifications.

This gradual production process is beneficial for animal feed and fertilizer applications:

  • Drying at a low temperature avoids the formation of biologically unavailable metha-phosphates and/or pyro-phosphates and results in a high quality digestible product
  • As a crystallization process it ensures a very predictable and stable composition as well as a high purity of end products that is virtually free of any undesirable substances
  • The hydrated crystalline structure is recognized as being nutritionally beneficial
  • The drying process guarantees a very fine and high quality free flowing product

Thanks to the high digestibility and solubility, PB Dical 17 provides a high feed conversion, intake and growth in animal feed. In addition, it ensures a good absorption of nutrients to the plants.
