Iphepha le-kraft eliyisicaba elingaphansi kwe-flat bold coffee packing elibolayo elingaphansi Isikhwama se-Gusset Esingasetshenziswa Kabusha Esingaphansi

Ukupakisha ubhontshisi wekhofi othosiwe (impuphu) kuyindlela ehlukahlukene kakhulu yokupakisha ikhofi. Njengoba ubhontshisi wekhofi ukhiqiza i-carbon dioxide ngokwemvelo ngemva kokubhaka, ukupakisha ngqo kungabangela umonakalo wokupakisha kalula, futhi ukuchayeka isikhathi eside emoyeni kuzobangela ukulahlekelwa yiphunga futhi kuholele kumafutha nephunga ekhofini. Ukushiswa kwe-oxidation kwezithako kubangela ukuwohloka kwekhwalithi. Ngakho-ke, ukupakisha ubhontshisi wekhofi (impuphu) kubaluleke kakhulu.

Okuvame ukusetshenziswa emakethe ukupakisha okuhlanganisiwe, okuwukubili noma ngaphezulu okuhlanganiswe ngenqubo eyodwa noma ngaphezulu eyomile yokwakha ukupakisha okunemisebenzi ethile. Ngokuvamile, kungahlukaniswa kube ungqimba lwesisekelo, ungqimba olusebenzayo kanye nongqimba lokuvala ukushisa. Ungqimba lwesisekelo ludlala indima yobuhle, ukuphrinta kanye nokumelana nomswakama. Njenge-BOPP, i-BOPET, i-BOPA, i-MT, i-KOP, i-KPET, njll.; ungqimba olusebenzayo ludlala indima yokuvikela nokuvikela ukukhanya.

Uma uke waqaphela izikhwama zekhofi esitolo esikhulu noma esitolo sekhofi, uzobona ukuthi izikhwama eziningi zinembobo encane noma ivalvu yepulasitiki eduze kwaphezulu. Le valve idlala indima ebalulekile ekugcineni ikhofi isha futhi imnandi.

Ivalvu iyi-vent enendlela eyodwa evumela ubhontshisi wekhofi kanye ne-coffee grounds ukuthi ikhiphe kancane kancane i-carbon dioxide (CO2) kanye namanye amagesi aguquguqukayo esikhwameni ngaphandle kokuthinta umoya wangaphandle, owaziwa nangokuthi i-valve valve egcina ihlanzekile, i-aroma valve noma i-coffee valve.

Ukusabela okuningi kwamakhemikhali kwenzeka lapho kushiswa ikhofi, futhi amagesi aguquguqukayo njenge-carbon dioxide akhiwa ngaphakathi kwebhontshisi. Lawa magesi anezela ukunambitheka ekhofini, kodwa ayaqhubeka nokukhipha isikhashana. Ngemva kokubhaka, i-carbon dioxide iqala ukuphuma, kodwa kuthatha amasonto ambalwa ukuthi inyamalale ngokuphelele. Le valve ivumela i-carbon dioxide ukuthi ikhishwe futhi ivimbele umoya-mpilo ukuthi ungene. Le nqubo ivimbela i-oxidation futhi yandisa isikhathi sokuphila. Lapho i-carbon dioxide ikhishwa, ibangela ingcindezi ngaphakathi kwephakheji, okubangela ukuthi i-gasket yerabha eguquguqukayo iguquguquke futhi ikhulule igesi. Ngemva kokuthi isigaba sokukhululwa sesiphelile, ingcindezi yangaphakathi neyangaphandle iyalinganiswa, i-gasket yerabha ibuyela esimweni sayo sokuqala esiyisicaba, futhi iphakheji ivalwa futhi.

I-valve ikusiza futhi ukuthi ukhethe ikhofi lakho. Ngoba ngokuhamba kwesikhathi iphunga lekhofi lizophuma nge-valve njengoba i-carbon dioxide ikhula, iphunga lizoncipha njengoba ikhofi liguga. Uma ufuna ukuhlola ukuthi ubhontshisi usha ngaphambi kokuthenga, ungacindezela isikhwama kancane ukuze ukhiphe igesi nge-valve. Iphunga elinamandla lekhofi liyisibonakaliso esihle sokuthi ubhontshisi usha yini, uma unganuki kakhulu ngemva kokuyicindezela kancane, kusho ukuthi ikhofi alisha kangako.
