Batch Cooker

Batch Cooker

Here is a summary of the provided information about the batch cooker in English.


The batch cooker is a simple, steam-heated machine used since the 1940s to process, cook, and dry materials in a single batch.

Primary Uses

  • Meat, Bone, and Intestines: Fried and dried at high temperatures (135°C) in an oil bath, then pressed with a high-pressure press to separate the fat
  •  Mixed Poultry Offal (including feathers), Feathers, Wool, and Hog Hair: Hydrolyzed (broken down with water and heat) and dried to produce animal feed
  • Blood: Cooked and dried to create blood meal

Machine Specifications

  • Design: Features a heated shell with a steam jacket and a heated mixing rotor.
  • Capacity: Available in various sizes, such as 1,700, 5,000, and 10,000 liters.
  • Operation: Can withstand internal pressure up to 5 bar but operates at approximately 3 bar.
Today, batch cookers are best suited for small-scale, low-cost rendering operations, while continuous systems are used for larger capacities.
