A 150 kg rice puffing machine is a used for puffing rice grains to create a popular snack known as rice cakes. The machine typically consists of a hopper for feeding the rice grains, a heating system for cooking the grains, and a pressurized chamber for puffing the grains. To use the 150 Kg rice puffing machine, the rice grains are first loaded into the hopper. The machine is then heated to the appropriate temperature. Once the machine has reached the desired temperature, the rice grains are fed into the pressurized chamber, where they are rapidly heated and pressurized. The combination of heat and pressure causes the rice grains to expand, creating the characteristic puffed texture of rice cakes.
