Abbreviation for "Direct Environmental Load Focussed Inactivation" (meaning in German: direct inactivation directed at the environmental impact). The company "Delfin Alliance" is a group of interests founded by the two companies Rudolf Ohlinger (Germany) and Juvenal Ferreira da Silva (Portugal). The process "dolphin" developed in this group is used in the production of natural corks. Everyone
cork is pervaded by pores (lenticels) in which different
microorganisms exist. Likewise, each cork contains moisture that already at more than 8% to 10% the growth of harmful microorganisms such as
molds favored. Mushrooms are instrumental in the formation of the chemical trichloroanisole (TCA) in the cork, which is the cause of the dreaded
corked is.
In the dolphin process, the microorganisms are vaporized or expelled and also killed in the cork inside microorganisms and their permanent forms such as the spores. There is also no longer the risk that impurities are formed again, since the responsible microorganisms are completely eliminated. It is a so-called dielectric (capacitive) heating, which generates high temperatures exactly at the desired location (in the entire cork, outside and inside). In principle, this technique is also used in a microwave oven. The Korkschmecker problem could not be solved satisfactorily. See also other alternatives below
