Kwicala elingasemva le-aluminium foil ikofu bag Sihlala sijonga ivalve esetyhula etshoneyo enomngxuma omncinci ojikeleze kuyo.Oku kungasentla kunzima ukwazisa indima yale valve.Iimbotyi zekofu ezibhakiweyo, ezitywinwe ngeengxowa ze-aluminium foil, ngenxa yesithintelo esihle kunye ne-Paushan i-aluminium foil, inokuthintela iimbotyi zekofu kunye noqhagamshelwano olulula kunye nomoya kunye nokufaka iphunga ngokukhawuleza ukusabalalisa kunye ne-oxidation.Olu fakelo lokukhupha lubizwa ngokuba yi-valve yendlela enye, eyaziwa ngokuba yi-aluminium foil coffee bag yendlela enye ephefumlayo, esetyenziselwa indlela enye yokuphuma kwingxowa ye-aluminium yefoil yegesi.

Ivalve yendlela enye yokukhupha iyahluka kwezinye izinto kuba ivalve yendlela enye ine-strainer enokuthi ihlukanise ifuthe ledatha yomgubo kwivalve yokukhupha ngelixa igas ikhutshwa kwingxowa yokupakisha ngelixa ingavumeli isisiqili (kubandakanywa nevalve yokuphuma). uthuli) ngaphakathi kwiphakheji phuma, kunye nokuqinisekisa ukuba umoya wangaphandle awunakungena engxoweni.Ekubeni ikofu iyabhaka ixesha elithile iya kuqhubeka ikhupha i-carbon dioxide (CO2), ngaphandle kwe-valve yendlela enye ye-aluminium foil bag yekofu iya kuzaliswa ngegesi, kulula ukugqabhuka, i-valve yendlela enye ingaba kwi-valve. ukukhutshwa kwe-carbon dioxide kwi-aluminium foil ibhegi yekhofi ye-oxygen ekhutshwe, ukukhusela i-oyile ye-coffee oxidation, ichaphazela umgangatho wekofu.

Ubukho beevalve zendlela enye, kodwa kunye nokukhetha kwethu ikofu kunokhetho oluninzi.
