Bone meat meal can be made from almost any type of animal, but is generally manufactured from dead livestock animal that contain a high percentage of bones and oil, and is usually deemed not suitable for direct human consumption.

Production Process Description
Bone meat meal is made on the process of cooking, pressing, drying, and grinding, made from animal meat and bone and no other matter has been added. It is a solid product from which most of the water is removed and some or most of the oil is removed. Four or five tonnes of animal meat are needed to manufacture one tonne of dry bone meat meal.

1.Cooking: A high temperature cooker is a long, steam-jacketed cylinder through which the material are moved by a screw conveyor. This is a critical stage in preparing the finished meal, as incomplete cooking means the liquid from the material cannot be pressed out satisfactorily and overcooking makes the material too soft for pressing. No drying occurs in the cooking stage.

2.Pressing: A perforated tube with increasing pressure is used for this process. This stage involves removing some of the oil and water from the material and the solid is known as press cake. The water content in pressing is reduced from 70% to about 50% and oil is reduced to 4%.

3.Drying: If the meal is under-dried, moulds or bacteria may grow. If it is over-dried, scorching may occur and this reduces the nutritional value of the meal.

4.Grinding: This last step in processing involves the breakdown of any lumps or particles of bone.

1.Direct: Very hot air at a temperature of 500°C (932°F) is passed over the material as it is tumbled rapidly in a cylindrical drum. This is the quicker method, but heat damage is much more likely if the process is not carefully controlled.
2.Indirect: A cylinder containing steam-heated discs is used, which also tumbles the meal.
