Making Duckweed into feed pallets

Making Duckweed into feed pallets

  Based on analytical formula, the ingredients components are mixed in order to provide the targeted crude protein %.

 Crude protein for Ducweed    : approx 40%,
                             Rice Bran   : approx 9%
                             Fish Meal   : approx 52%
                 
  For our products, we are able to provide a range of crude protein from 10% - 30%. The higher the crude protein %, the higher price the product is.  The is due to the crude protein is needed to be  converted into the animal or fish protein after consuming the feed pallets.  In other words, they will increase the weights. However, with the crude protein alone, they are not converted effectively.  The Feed Conversion Rate (FCR) is low.  

  In Duckweed, the Amino Acid of Lysine & Methionine is very high. They will increase the FCR, and act as booster for the growth.  There are many researches demonstrate that with Lysine and Methionine,  the pallets with only 19% Crude Protein showing the similar results of 32% Crude Protein that without Lysine and Methionine.

  With this in mind, we have produce a special formula fish pallets for Arowana Fish. Will discuss in detail about the Arowana Fish pallets.

  The duckweed after the cleansing process, they need to be drained off excessive water. The components are weighed and mixed according to the recipe.

    The grinding process that we are showing here is the prototype, it is manual for the time being. However,  the process is being developed into highly automation.  The output of the grinding process is still wet, and they need to be dried immediately. The cheapest way is using the sunlight, but there will very very inconvenient during the raining day.

   Hence, we are developing an automatic drying process with burner. I will share it with you at later articles.

  The dried products will be collected for making feed pallets according to the size: 2mm, 4mm or 6mm.  Some customers want the product in powder form. Will discuss later.

   See you.
