Chest opening is a crucial step in cattle slaughtering, occurring after pre-skinning and before evisceration. The main task of this step is to saw open the cow’s sternum, creating conditions for the subsequent removal of internal organs such as the heart, liver, and lungs. Depending on the size and conditions of the slaughterhouse, different chest opening equipment can be selected:
- Pneumatic Chest Opening Saw: The most commonly used equipment, powered by compressed air (working pressure 0.6-0.8 MPa) with a reciprocating saw blade. It features high power, light weight, and flexible operation, suitable for large, medium, and small-scale cattle slaughterhouses. Technical parameters: air consumption 1.5-2.0 m³/min, saw blade stroke 50-80 mm, saw blade frequency 3000-5000 times/minute, equipment weight 3.5-5.0 kg, main body material stainless steel or aluminum alloy.
- Electric Chest Opening Saw: Powered by 380V/220V power supply, using circular or reciprocating saw blades. It is powerful and requires no air source, making it ideal for slaughterhouses without compressed air systems.
