The three-phase froth flow velocity that the present invention ejects is fast, and flow is big, and foam is good in the trickling of pasta and spreadability.
Case study on implementation 3:
The experiment of foam burn resistance:
(1) the small food tray of diameter 0.5m is placed among the big food tray of diameter 1.48m, pours into 4 liters of solvent naphthas in small food tray, big oil
6 liters of solvent naphthas are poured into disk, are laid with 1cm thickness water layer under big food tray.
(2) 30L foam is laid on the pasta in big food tray.
(3) oil for lighting small food tray records the time that 25% burning and 100% burning occurs in oil in big food tray.
The positive pressure three-phase froth 30L (coefficient of foaming 7.5) ejected in apparatus of the present invention is poured into big food tray and is carried out
Burn resistance experiment.After igniting, there is flare in the small food tray periphery 4.5min；To after 7.min, big food tray 25% burns；7.7min big
Food tray 60% burns；Always imperfect combustion, until after-flame oily in big food tray.
Positive pressure two-phase foam 30L (coefficient of foaming 7.5) is poured into progress burn resistance experiment in big food tray.Light a fire 2.5min
Afterwards, there is flare in small food tray periphery；To after 5.5min, big food tray 25% burns；The big food tray 100% of 6.0min burns.
The burn resistance of the positive pressure three-phase froth ejected in patent device is apparently higher than gas-liquid two-phase foam.
