The poultry rendering process handles the by-products of the poultry slaughter process. The poultry by-products that are not intended for human consumption are transformed into valuable proteins, minerals and oils.
Poultry is a general term used for the animals such as chicken, turkey, ducks, geese etc.. The poultry by-products consist of soft meat, feathers, blood, and deboning residue but can also consist of dead on arrival (DOA), deboning residue and farm waste.
None of the poultry by-products are thrown away! However, to use the poultry by-products in other processes they have to be treated first. Our systems transfer the poultry by-products into Meat and bone meal, Whole meal, Feathers meal, Blood meal and fats/tallow/oils. This process is called rendering. These meals can be sold to the pet food industry, feed industry etc. and the fats to the pharmaceutical industry, chemical industry, oil industry and many other. The way of processing determines the value of the end products. This is why we claim “Rendering is not waste handling it’s nutrient management!”
The processing of the poultry by-products starts with raw material handling, followed by heat treatment to reduce the moisture content and to kill micro-organisms. Separation of the melted oil from the solids (protein) is achieved through draining and pressing. The solid fraction is then ground into a powder, such as whole meal, poultry meat meal, feather meal, blood meal and poultry oils. The oil can be clarified through decanting or settling.
