The key to this machine is instant high temperature and uniform singeing. An array of high-efficiency gas burners creates a uniform, stable curtain of high-temperature flame within the furnace chamber. An intelligent PID temperature control system precisely regulates the gas-to-air ratio, maintaining stable furnace temperature to achieve effective singeing without scorching the skin. Specially designed heat-resistant conveyor chains carry carcasses steadily through the high-temperature zone. The machine features front baffle plates and a rear water curtain cooling section. The baffles direct flames evenly over all parts of the carcass (especially the belly and legs), while the water curtain immediately cools the carcass after singeing, preventing residual heat from causing further effect. The fully enclosed furnace body and multiple gas safety interlock devices ensure a high degree of operational safety.
The standard furnace body length is 6-8 meters, with a processing capacity of 300-500 heads per hour. The dwell time in the high-temperature zone can be precisely adjusted between 10-20 seconds. The internal furnace width is ample to accommodate pigs of different sizes. The control cabinet has an IP54 protection rating and can store multiple production process parameters. The machine operates with low noise and complete combustion, meeting environmental emission standards. It requires connection to a suitable gas supply line and exhaust system.
This machine is installed between the dehairer (or scraper) and the final polisher/washer. The moist carcass with minor hair residues enters the singeing furnace, where it is briefly passed through the high-temperature flame, instantly carbonizing surface residues. The carcass then immediately enters the water curtain cooling section, where the surface temperature drops sharply, and the carbonized layer becomes brittle. Finally, the carcass enters the polisher or scrubber, where the brittle carbonized material is easily brushed away, yielding a final product with a golden, clean, and smooth skin surface. The singeing process is a critical step in producing high-quality pork sides. It effectively kills surface microorganisms, improves appearance, and lays an excellent foundation for subsequent market sales or cutting operations, making it a key link in modern pig slaughter lines for adding product value.
