POULTRY RENDERING MACHINES

POULTRY RENDERING MACHINES

WHAT IS POULTRY RENDERING?

Rendering is a process that changes animal waste tissue into useable, valuable materials. Rendering is referring to whole animal fatty tissue. Materials like dead chicken, chicken waste, tissues, and feathers are converted into high protein meal like poultry meal and feather meal. Rendering can be carried out on chicken waste coming from poultry slaughterhouses and poultry processing plants. Animal leftovers consist of necks, heads, feet, undeveloped eggs, intestines, and gizzards. The nutrient content of a meal can vary and depends on the type of processed raw material. A poultry meal is a high-quality feed material that contains fatty acids, amino acids, minerals, and oils. For recycling materials turkey, ducks and geese are included. TG-Machines rendering solutions turn animal by-products into high-quality protein meal. Processing offals into meal starts with raw material handling and requires several steps. Low-temperature wet rendering by cooking under steam pressure used to be the most popular way of processing poultry by-products. Over time, the dry-rendering process becomes popular, which offers a meal of higher quality. Animal leftovers are cooked, sterilized, and dried to 8% of moisture. Fat extraction level is recommended at yields between 10% to 12%. Draining and pressing are applied for the separation of the melted oil from the solid proteins. Oil can be clarified by settling or decanting. Dried poultry by-products are ground into a powder, creating poultry meat meal, feather meal, and blood meal. Converting slaughterhouse by-products, into feed, is a good way to solve the environmental problems caused by animal waste. Animal by-products can be dangerous for the environment. If not properly managed, they can cause air pollution and water contamination by vermin, bacteria, and viruses.

 

WHAT IS A POULTRY MEAL USED FOR?

This type of meal is a powerful addition to animal nutrition and a cheap source of protein. It can be used for feed for horses, pigs, chickens, and cows. It is very important when the animals are not fed by additional vitamins and minerals. It is a valuable component of fodder for fur and fish. Chicken meal is used as a protein source in animal feed. It is very popular on farms because the low prices of meal allow improving animal nutrition without much effort. Poultry meal contains phosphorus and calcium, which are difficult to obtain if the animals do not have free access to pasture. This meal does not provide all the necessary minerals by itself, but it is suitable as a feed for predatory fish.

 

HOW TO HYDROLYZE FEATHERS IN RENDERING PLANTS?

Feather meal is made by grinding and drying hydrolyzed poultry feathers left over from the processing of animal carcasses. The sterilization process can be carried out in a batch cooker or in a continuous hydrolyzer under elevated heat and pressure. The pressure hydrolysis process is necessary to breaks down hard protein bonds of feathers, which are called keratin. The meal contains amino acids that can be found in raw feathers and in hog hair. Breaking down the protein bonds makes feathers more digestible.

 

WHAT IS A FEATHER MEAL USED FOR?

This type of meal is a useful source of protein and an ingredient for animal feed. In general, it improves the quality of the fur and keeps the animals healthy. Low ash content, allows for better digestibility between different species of animals. Feather meal is also used in fish foods. In particular, it is the best source of protein for large predatory fish - trout, sea bream, salmon, catfish, Japanese flounder, carp, and tilapia. It contains large amounts of nitrogen. This content makes a meal an excellent organic fertilizer. It is a real source of protein. This meal does not contain enough minerals compared to chicken meal and may require additional dietary supplements.
