Kudula kwachikale ndiko kugwiritsa ntchito mpeni wokhala ndi m'mphepete mwake kuti ukanize zomwe zikudulidwa. Kupanikizika kumeneku kumakhazikika pamphepete mwa tsamba, kupanikizika kumakhala kwakukulu kuposa mphamvu yometa ubweya wa zinthu zomwe zimadulidwa, chomangira cha molekyulu cha zinthucho chimachotsedwa, ndipo chimadulidwa. Popeza kuti zinthuzo zimakokedwa ndi kuponderezedwa, chigawo chodula cha chida chodulira chiyenera kukhala chakuthwa, ndipo zinthuzo ziyenera kukhala zopanikizika kwambiri. Chotsatira chodula sichili chabwino kwa zipangizo zofewa komanso zotanuka, koma ndizovuta kwa zipangizo zomata
Poyerekeza ndi miyambo kudula mipeni chakudya, akupanga mkate odula safuna lakuthwa konsekonse, kapena amafuna kwambiri kukakamizidwa, ndipo chakudya si kuonongeka. Pa nthawi yomweyi, chifukwa tsamba lodula likuchita kugwedezeka kwa ultrasonic, kukana kwa mikangano kumakhala kochepa, ndipo zinthu zomwe ziyenera kudulidwa sizili zophweka kumamatira kutsamba. Izi zida zomata komanso zotanuka, zida zachisanu, monga keke ya kirimu, ayisikilimu, ndi zina.
