Do you know how to make hydrolyzed feather meal? Let’s go through the below steps for your reference.
The first step in the production of hydrolyzed feather meal is the collection of raw feathers. These feathers mainly come from the waste of poultry slaughtering, and a large number of feathers need to be collected for the production of feather meal.
After pre-treatment, the feathers enter the critical dewatering stage, where dewatering equipment removes excess water in preparation for subsequent processing.
Next, the feathers are conveyed in a closed reaction vessel and subjected to a high-pressure cooking process, where they are hydrolyzed under certain temperatures and pressures with the addition of appropriate acidic or alkaline media to break down the hard keratin structure and transform it into a digestible and absorbable form.
After high-temperature hydrolysis, the material is stirred to ensure homogeneity and enzymes may be added at this stage to further improve protein utilization.
Subsequently, the material is transferred to the steam drying system for evaporation and dehydration at the appropriate temperature, which not only maintains the nutrient content of the product, but also achieves the ideal drying effect.
After steam drying, the hydrolyzed feather meal will be cooled quickly to prevent the loss of nutrients and changes in color. It is then finely screened to remove particles that do not meet the particle size requirements.
The screened feather meal is then processed through a milling machine into a fine powder that meets feed standards. Finally, the finished feather meal is weighed, bagged and sealed according to specifications to ensure stable quality during storage and transport.
