Food processing technology chi thar angin puffing technology hi kum 1910 atang khan a lo piang tan a, kum 1950 chhoah khan United States-ah pet food-ah hman a ni. United States chuan extrusion principle hmangin pet food a siam hmasa ber a, chu chu extruder hmanga siam a ni. Screw leh screw sleeve chu raw material press-in a lum a, a pressurize a, high-temperature leh high-pressure food chu mold cavity-ah extrude a ni a, volume zau taka tihzauh dan chu sudden decompression hmangin a thleng thei a ni.
Puffing process hmanga ui chaw siam dan hman chhan ber chu:
