Granulation dinhmun pangngaiah chuan vitamin hloh hi a tlangpuiin 10% aia sang a ni. Granulation laiin bacteria nung siam chhuah hloh: Feed-a bacteria nung siamte chu lactic acid bacteria, streptococci, bacillus leh yeast-ah te dah a ni ber a, granulation laiin an dinhmun a inang lo hle. Active yeast cells awm zat chu 99.7% in an hloh a, active cells pawh a awm lo tluk a ni.
Fish feed extrusion process laiin heat sensitive components hloh:
1. Expansion process-a vitamin hloh, temperature, pressure, friction leh moisture te hian vitamin hloh a thlen thei. Vitamin A, vitamin D3, leh folic acid te chu 120℃ah chuan puffed feed ah 11% velin an hloh a ni .
2. Expansion process chhunga enzyme siamna hloh chu a tlangpuiin temperature 120-150℃C a thleng a, chu chu granulation temperature aiin a sang zawk. Chutiang dinhmun hnuaiah chuan enzyme siam tam zawk chuan an hnathawh a hloh vek ang. 110℃C-ah chuan activity retention rate chu phytase a ni a; 110℃C-a -glucanase leh cellulase awm theihna chu teh a la ni lo.
3. Expansion process chhunga bacteria nung siam chhuah hloh chu expansion process chhunga bacteria nung buatsaihna hloh chu granulation condition hnuaia hloh aiin a tam zawk hle. Puffing temperature 120℃aia sang chuan Lactobacillus, Streptococcus, Bacillus leh yeast te hnathawh chu a hloh vek dawn a, chu chu tunah hian hman tam zawk a ni.
A hnuaia point hrang hrangte hi ngaihven rawh. Nga ei tur extrusion machine .:
1. Control processing temperature, additive activity nghawng thei tur khawpa sang lo .
2. Tui awm zat tihtlem la, a vawt chhuak rawh.
3. Pulverization particle size hi a rit lutuk a, a lian lutuk hian a puitlin leh a chaw ei a nghawng a, digestive system hnathawh dan pangngai a nghawng nasa lutuk bawk.
4. Feed nutrition hloh chu a ruala control. Nutrition lei tawhte dikzia ngaihven la, thil chhia lei suh. Storage hun hi a rei lutuk tur a ni lo, nutrition pawh a nghawng dawn a ni. Summer time hi a tawi a, thlasik hun pawh a hun takah pawhsei theih a ni.
