Proces testovania sa za\u010d\u00edna umiestnen\u00edm troch r\u00f4znych druhov zemiakov\u00fdch lupienkov do kompresn\u00fd pr\u00edpravok<\/strong>. V tejto \u0161t\u00fadii sa pou\u017eili vzorky be\u017en\u00fdch zemiakov\u00fdch lupienkov, \u010dipsov a \u010dipsov v r\u00fdchlovarnej kanvici. \u010cipsy boli stla\u010den\u00e9 pri r\u00fdchlosti 1000 mm\/min so \u0161tyrmi \u00farov\u0148ami stla\u010denia pri posunut\u00ed 120 mm, 100 mm, 80 mm a 60 mm.<\/p>\n\n\n\n

V\u00fdsledky z kompresn\u00fd test<\/strong> uk\u00e1zali jasn\u00e9 rozdiely medzi tromi typmi \u010dipov. Sila potrebn\u00e1 na ka\u017ed\u00fd cyklus stla\u010denia bola v pr\u00edpade \u010dipsov z varnej kanvice v porovnan\u00ed s be\u017en\u00fdmi zemiakov\u00fdmi \u010dipsami v\u00fdrazne vy\u0161\u0161ia, \u010do nazna\u010duje, \u017ee \u010dipsy z varnej kanvice s\u00fa tvrd\u0161ie.<\/p>\n\n\n\n
