Meat and Bone Meal Processing Equipment

The Meat and Bone Meal Processing Equipment converts livestock and poultry slaughter waste, diseased and dead livestock, and other materials into high-quality meat and bone meal and animal fat through processes such as crushing, high-temperature and high-pressure steaming and sterilization, pressing and degreasing, and drying and pulverizing.

Equipment Introduction

Meat and bone meal equipment processes discarded livestock waste, such as meat, bones, and offal, into powdered protein feed. Meat and bone meal generally contains 50-60% crude protein and greater than 4.4% phosphorus, while meat meal has a crude protein content of over 55% and a phosphorus content of less than 4.4%.

In industrialized countries, meat and bone meal processing equipment boasts larger capacity and a wider variety, including equipment for skinning, depilation, crushing, mixing, steaming, degreasing, drying, grinding, and packaging. These equipment is also equipped with various air treatment and wastewater purification devices, and the production process tends to be fully enclosed to minimize environmental pollution. A Dutch manufacturer's poultry waste processing process involves the raw materials being sent through a cleaning device or directly by vacuum equipment into a storage tank for temporary storage. From there, they are batched into a steamer and dryer. The dried powder is then discharged into containers and transported by conveyor to packaging locations. If the fat content is high, the powder requires further degreasing. As a professional manufacturer, Shandong Chengming has been developing for 20 years and has been moving towards high international standards. Through research and development and innovation, we have achieved quality excellence. In the future, we will continue to improve and provide better choices for global buyers.

Main components

Crusher: First, raw materials such as pig bones and cattle bones are crushed by animal carcass crusher. Generally, they are crushed into meat pieces of about 30-50mm for subsequent processing.

Chemical Drying Machine: Crushed materials are pumped into a sealed chemical drying machine via a feed pump. While continuously agitated, a high-temperature circulating heat source is introduced through the interlayer to sterilize the materials at high temperatures and pressures. The heat source does not directly contact the materials during the drying process, instead utilizing the moisture in the animal's body to generate pressure through vaporization. For example, the core temperature of the processed material can reach 135°C, with a pressure of 0.25 MPa and a holding time of 30 minutes. After chemical drying, the material is vacuum-dried to reduce its moisture content to 10%-12%.

Press: The dried material is transported to the press through a screw conveyor for degreasing. After the oil residue is separated, meat and bone residue and animal fat are obtained.

Cooling and crushing equipment: The meat and bone residue is cooled to room temperature after being treated by the air cooling system, and then crushed by the crushing equipment to obtain the finished meat and bone meal. Finally, it can be packaged and stored by the automatic packaging machine.
