Yiziphi izindlela zokuvala i-vacuum ze- inyama yenkomo kanye nenyama yemvu?

1. Ukukhipha umoya nokuvala: Esisikini senyama yenkomo nesemvu, umoya osesitsheni sokupakisha ukhishwa ngephampu yevacuum. Ngemva kokufinyelela izinga elithile le-vacuum, ivalwa ngokushesha. I-vacuum tumbler yenza isiqukathi sokupakisha sibe yisimo se-vacuum.

2. Ukushisisa nokuqeda amandla: ngokushisisa isitsha esigcwele isisiki senyama yenkomo nesemvu, umoya osesitsheni sokupakisha uyaphuma ngokunwebeka okushisayo komoya kanye nokuhwamuka komswakama ekudleni, bese kuthi ngemva kokuvala nokupholisa, kwakhiwa isitsha sokupakisha. Izinga elithile le-vacuum. Uma kuqhathaniswa nendlela yokukhipha ukushisa, indlela yokukhipha umoya kanye nendlela yokuvala inganciphisa isikhathi sokushiswa okuphakathi futhi ilondoloze kangcono umbala nephunga elimnandi lokudla.

Uma kuqhathaniswa, lezi ezimbili zinezici zazo futhi ziyindlela evame ukusetshenziswa yokuvala i-vacuum yezisiki zenyama yenkomo neyemvu. Phakathi kwazo, indlela yokuvala i-air-extracting sealing isetshenziswa kabanzi, ikakhulukazi emikhiqizweni enokushisa okuhamba kancane kanye nokukhishwa kwe-exhaust conduction.
