Htunghking hku lang ai single screw feed jak hte kaga jak ni hte shingdaw yu yang, twin-screw nga shat jak ni gaw, npawt nhpang hkrang shapraw ai lam, galaw shapraw ai atsam, galaw shapraw ai arung arai ni a hkam kaja lam, bungli galaw ai lam hta galai shai wa lu ai lam ni hta grai kaja ai rawt jat lam ni hpe lu la wa sai. Shanhte a madung akyu ara ni hpe lawu na daw manga hku nna shingdaw mai ai:
1, Twin-screw nga shadu ai jak gaw, grau tsaw ai madang na process integration nga ai, dai majaw, galaw shapraw ai atsam hpe law law lang jat wa shangun ai .
Htunghking malu masha jaw ai jak ni hta, laksan mixer, maturation jak ni, hte kaga arung arai ni ra ai, bra ayai ai ladat ni hte lata hte matut mahkai ra ai majaw, arung arai sum mat ai, aten sum mat ai, bungli galaw ai lam hta n-gun n rawng ai lam ni byin chye ai.

2, Twin-screw nga shat jak gaw grau n-gun ja ai arung arai ni hpe galaw shapraw lu ai atsam nga ai hte raw material hpe grau dam lada ai hku galai shai lu ai atsam nga ai .
Traditional single screw feed machines rely on the frictional force between the material and the barrel for conveying, and have strict requirements for the characteristics of the raw materials. If high fiber (such as algae, straw powder), high moisture (>18%), or high oil (>10% raw materials ni hpe bang dat yang, "slipping and blockage" (sh) n kaja ai hku htaw sa ai zawn re ai manghkang ni hpe hkrum na matu loi ai. Twin-screw (screw lahkawng gaw langai hte langai shingdaw nna arung arai ni hpe shadut ai) a atik anang htawt sit ai atsam gaw ndai hkra machyi ai lam hpe tsep kawp hparan ya lu ai:

3, Twin screw nga shadu jak a arai a hkam kaja lam gaw grau ngang grin ai, madung masat kumla ni hpe hkum tsup hkra galaw ai
Hka kata na malu masha hta "nutritional uniformity", "maturity", "water stability" ni a matu ra kadawn ai lam ni gaw, dusat dumyeng hte u ni a malu masha hta grau law ai.

Twin-screw nga shadu jak gaw, npawt nhpang hte hpaji masa akyu ni hku nna, quality hpe jat wa shangun ai:

Htunghking hku nna malu masha jaw ai jak ni gaw screw structure hte pressure hpe hkang lu ai atsam ni a majaw shadawn sharam sha nga ai rai nna, law malawng gaw hka ntsa e lwi ai (sh) lup mat ai malu masha hpe sha shapraw lu ai, n-gun n rawng ai particle size hpe galai shai ra ai. Langai hte langai -screwnga shadu jakn-gun rawng ai hka htung malu masha amyu masum hpe hkrak hkrak gram lajang nna, n-gun rawng ai hku galaw lu ai (screw lawan ai, barrel a n-gun rawng ai, n-gun rawng ai hka htung a masat masa, cutter a lawan ai, etc.):
Floating feed: grass carp hte sea bass zawn re ai ntsa tsang na nga ni a matu htuk manu ai;

Semi sinking feed: crucian carp hte shrimp zawn re ai lapran hte lawu daw na arai ni hpe jaw sha na matu htuk manu ai.
Dai laman, hka kata na nli tum ni a rawt jat galu kaba wa ai ladaw amyu myu hta lu sha ra kadawn ai lam ni hpe hkap la lu na matu, npawt nhpang daw ni hpe ayan galai shai ra ai lam n nga ai sha, 0.5-15mm lapran na particle diameter hpe lawan ladan galai shai mai ai.
Htunghking hku lang ai single screw feed jak ni a screw hte barrel gaw lawan ladan hten mat chye ai (grau nna grai n-gun ja ai raw material ni hpe galaw ai shaloi), shing nrai, pat mat ai hpang jasan jaseng na matu yak hkak ai majaw, jak ni hpe n-gun n rawng ai aten hte gram lajang na matu gumhpraw law law jai lang ra ai. Twin-screw a hkrang shapraw ai lamnga shadu jakindustrial grade matut manoi galaw shapraw na matu grau htap htuk ai:
