Ukuvuna Kwezithelo zeWayini

©Louise Brodie
Ngaphambi kokuvuna kubalulekile ukuba nohlelo lokuvuna. Lolu hlelo lokuvuna luzofaka isivuno esilindelekile (ngamathani), usuku lokuvuna olulinganisiwe, inani labasebenzi elidingekile, ukuqashiswa kwemishini kanye nezindleko zokuthutha kwamagilebhisi ukuya emgodini wewayini. Kumelwe futhi kwenziwe ilungiselelo lokunciphisa ukulumbana neoksijini kwamagilebhisi ngesikhathi sokuthutha, ukunciphisa ukulimaza nokuqinisekisa izindinganiso zokuphepha nezokuhlanzeka.
Izinto ezidingekayo uma uvuna amagilebhisi owayini zinhlanganisa:
Amatekisi noma amaloli anamabhodlela amagilebhisi.
Izitshalo zokuvuna nezinsimbi zesisebenzi ngasinye.
Amakhadi esikhangiso (la makhadi aphawulwa ukuze anqume inani lomphongolo ogcwaliswe ngumsebenzi ngamunye).
Indlu yangasese namanzi okuphuza.
Impahla yokuhlenga ekuguleni lnamakhemikhali okuhlanza.
I-Refractometer yokuhlola njalo amazinga kashukela kumagilebhisi.

Ukuvuna Amagilebhisi Ewayini Ngezandla

Izithelo ezivuthiwe zinqunywa ngesikhumba sokuvuna futhi afakwe emakhakheni okuvuna. Lezi zikhwama zivame ukufakwa ngaphansi noma eduze nomvini. Lapho isikhwama sigcwele, sthululwa emgqomeni noma kuloli. Imigqomo yamagilebhisi ama-plastiki amakhulu noma izitsha zensimbi ezinamandla amathani amahlanu kuya kusithupha kodwa imithwalo igcinwa encane ukuze kugweme ukulimaza nokubunjwa kwejusi kanye nokulumbana neoksijini.
Amagilebhisi kumele athunyelwe emiphongolweni ngokushesha nangokunokwenzeka futhi angashiywa emi elangeni noma ekushiseni. Uma kunjalo, ijusi lingase liqale ukuvutha. I-potassium metabisulfite (K₂S₂O₅) ingafakwa emakhulwini omvini amhlophe ukuze kuncishiswe uketshezi futhi kuvimbele ukuvutshelwa kokuqala. (Ukuvuthwa kwesikhashana lapho ijusi igcine ibila ukwenza i-carbon dioxide ntshwala.
Ukuvuthwa kufanele kulawulwe ngokungeza imifino ethile emva kokuba umusi wamagilebhisi ususiwe, ushihliwe bese ufakwa emathangi.) Lapho amagilebhisi efika egumbini elingaphansi, ahlolwe ebhanini lokuhambisa kanye namaqabunga, izitshalo nezivini ezibolile zisusiwe ngaphambi kokuthi amagilebhisi abekwe ngaphakathi komshini wokuvuna ukuze akhiphe ijusi.

Ukuvuna Amagilebhisi eWayini Ngomishini

Umshini ungasetshenziswa ukuvuna iwayini ngezithelo zomvini. Lokhu kwenziwa ngezinhlelo eziguquguqukayo (eziphakeme) futhi kuvame ukusetshenziselwa ukuvuna imvuno ephezulu. Amabhontshisi asusiwe emivini ngokuhamba ngezintambo futhi izithelo ziqoqwe emgqomeni wokuvuna kumshini ngenkathi amaqabunga esuswa umoya ophezulu. Ukuzuzisa okuyinhloko okuvunwa kwemishini amagilebhisi anikezwa emiphongolweni ngokushesha kunokuvuna ngesandla.
Izindawo ezinkulu zezivini zingavuna ebusuku, kungadingekile amandla abasebenzi futhi kuvuna kungenziwa ngesikhathi samahora apholile. Lokhu kubaluleke kakhulu futhi ukunciphisa ukubila kwamagilebhisi. Inkinga yokuvunwa kwemishini ukulimala okungenzeka kwamagilebhisi (iziqu) nokuthi izithelo ezingavuthiwe zivunwa kanye nezivuthiwe.
