The core features of this Beef Bone Meal Processing Equipment are its adaptability to the physical properties of beef bones, resulting in higher density and a harder texture. Through enhanced crushing, high-temperature and high-pressure sterilization and degreasing, the safety, purity, and functionality of the finished product are ensured. Equipment configuration requires flexible adjustment based on production scale and product standards.
The key difficulty in processing beef bones lies in their hardness and high fat content, especially in the bone marrow. Therefore, Beef Bone Meal Processing Equipment must have stronger crushing capabilities and degreasing efficiency. The functions of each link of the equipment are as follows:
1. Pretreatment equipment: enhanced crushing (adapted to the hardness of cattle bones)
It is suitable for beef bones with tendons and marrow. It uses dual-axis staggered shearing to avoid entanglement. The crushing particle size is 30-50mm. It can process 0.8-3 tons per hour. The cutter head can be replaced regularly and is suitable for high-fat materials.
2. Sterilization and degreasing equipment: deep treatment (solving high oil problem)
This step is the core of ensuring the safety of beef bone meal (killing pathogenic bacteria such as Brucella and Salmonella) and improving its purity (reducing fat content). The degreasing effect needs to be enhanced based on the high-fat characteristics of beef bones.
Enhanced high temperature and high pressure canning: Through high temperature of 130-140℃ and high pressure of 0.2-0.35MPa (higher than the processing parameters for pig bones), the bone marrow and residual fat in the cattle bones are fully melted (liquid), while achieving 100% sterilization and preliminary separation of oil residue.
3. Drying and crushing equipment: finished product molding
In view of the "high calcium and high hardness" characteristics of cattle bone meal, it is necessary to select wear-resistant and fine drying and crushing equipment to ensure that the finished product has uniform particle size and retains nutrients.
Core requirements of drying equipment: After drying, the moisture content of the bone residue is ≤10% (lower than the standard of pig bone powder, because the calcium content of cattle bone powder is high and low moisture content can avoid agglomeration), while avoiding high temperature destruction of minerals such as calcium and phosphorus.
4. Crushing equipment:
The dried cattle bone residue is crushed into a specified particle size (80-120 mesh for feed grade, 150-200 mesh for food grade, and 300 mesh or above for high-end health product grade). The problem of "easy wear equipment" of cattle bone meal needs to be solved.
Using a hammer mill: Specially designed for feed grade, the hammer is made of high manganese steel (wear resistance increased by 50%), processing 2-8 tons per hour, crushing particle size uniformly, suitable for feed additive production.
5. Auxiliary and environmental protection equipment: ensuring continuous compliance
Conveying equipment: Closed screw conveyor (to avoid adhesion of high-fat materials) and negative pressure feed pump (for conveying during the crushing process to prevent dust diffusion) ensure continuous connection of each link.
Environmental protection equipment: Biological filter + spray tower: treats the malodorous waste gas generated in the chemical process and drying process.
