Animal fat oil rendering plant and equipment
Animal Fat and Oil Extraction Line, also known as a rendering plant. This process converts animal by-products (tissues, bones, offal) into stable, usable materials like tallow, lard, and protein meal.
Final Products & Applications of animal fat redering plant
Rendered Fat (Tallow, Lard, Poultry Fat):
- Edible: Cooking fats, baking, frying, food ingredients.
- Industrial: Biodiesel production, oleochemicals (soap, candles, lubricants, cosmetics), animal feed.
Protein Meal (Meat & Bone Meal, Poultry Meal):
- High-protein ingredient for livestock, poultry, and pet food.
Other Co-Products:
- Gelatin (from specific bones/hides).
- Animal Protein Condensate (from stickwater), used as a feed palatability enhancer.
Animal Fat and Oil Rendering Process Stages
A modern rendering line is a continuous, automated process that can be broken down into three key phases:
1. Raw Material Pre-Processing:
Heavy-duty crushers/pre-breakers and magnetic separators ensure uniform particle size and remove tramp metal, protecting downstream equipment.

2. Continuous Cooking & Conditioning:
Indirect-heated cooking system thermally treats the material, breaking down fat cells, coagulating protein, and reducing moisture in a controlled, energy-efficient manner.

3. Multi-Stage Separation:
- Mechanical Pressing: A high-pressure continuous screw press (expeller) extracts the maximum amount of residual fat from the cooked solids, producing dry press cake.
- Centrifugal Separation: A three-phase decanter centrifuge and a clarifying disc separator work in tandem to precisely separate finished fat, water (stickwater), and fine solids, ensuring pure product output.
4. By-Product Processing:
- Protein Meal Production: The press cake is ground, cooled, and stabilized to produce high-quality meat and bone meal (MBM) or poultry meal for animal feed.
- Stickwater Recovery: An evaporator concentrates solubles from the centrifuge effluent, creating a nutrient-rich animal protein concentrate to be recycled into the meal.
