Abubuwan da ake buƙata don kafa ɗakunan fermentation:

1. An fi amfani da ɗakin fermentation don aikin fermentation na shayi na shayi bayan mirgina, kuma girman ya kamata ya dace. Ya kamata a ƙayyade yankin bisa ga kololuwar samar da kamfani.
2. Ya kamata a saita kofofi da tagogi yadda ya kamata don sauƙaƙe samun iska da guje wa hasken rana kai tsaye.
3. Zai fi kyau a sami filin siminti mai ramuka a kusa da shi don sauƙin ruwa, kuma kada a sami matattun sasanninta da ke da wahalar zubarwa.
4. Dole ne a shigar da kayan aikin dumama da humidification na cikin gida don sarrafa zafin jiki na cikin gida a cikin kewayon 25 ℃ zuwa 45 ℃ da ƙarancin dangi a cikin kewayon 75% zuwa 98%.
5. An shigar da raƙuman ruwa a cikin ɗakin fermentation, tare da 8-10 yadudduka da aka sanya a cikin tsaka-tsakin 25 centimeters kowanne. An gina tire mai motsi a ciki, mai tsayin kusan santimita 12-15.
