Design parameters

Above mentioned figures are based on the following assumptions: slaughter capacity of 3000 birds per hour with a live bird weight of 1.8 kg, a water consumption of 15 liters per bird and 8 hours of production.

Required surface for installation of components mentioned is ca 80 - 100 m2. It is recommended to place the installation in a closed and dry room.

• Complete dry rendering plant designed and manufactured by Meyn
• Allows profitable recovery of protein by processing the normally inedible waste products resulting from the slaughter of broilers.
• Raw materials include offal, wet feathers, blood, heads, feet and dead on arrivals processed in natural proportions to achieve a uniform mixed protein meal
• Raw materials will be sterilized, hydrolyzed and dried in a cooker-drier to produce a mixed meal which can be used as part of the protein and energy source in the formulation of broiler feed rations.
• Rendering plant has been sized to process the inedible waste products in natural proportions resulting from the slaughter of 28.800 broilers per day, 6 hours of per day at an average live weight of 1.6 kg. This results in the following daily available quantities of raw materials:

1. * The quantity of 9504 kg of raw material will be treated in two (2) charges of 4752 kg in one 6500 liter cooker-drier, type MRE 6.5. The quantity of 19008 kg of raw material will be treated in four (4) charges of 4752 kg in one 6500 liter cooker-drier, type MRE 6.5
2. ** including loading and unloading
3. *** approximate yield of mixed meal product at an assumed moisture content of 10% and estimated fat content not exceeding 30% oil
