KEBO supplies antifoams for the temperature range of 40°C and higher in beet and cane sugar factories as well as for the flume water area in beet sugar factories. Based on their special formulation they have the ability to immediately distribute in the medium to be defoamed and to rapidly reach the interfaces being formed displacing the existing foam-forming agents (saponins, proteins, a.s.o.). These high-temperature antifoams show in all liquids a constantly high foam-destructing ability which is independent of the pH-value and kind and concentration of dissolved substances as well as of different retention times in the sugar juice. They are not steam-volatile. It can be explained by the mechanism of the processes at the interfaces that special kinds of defoamers can only be most effective at particular temperatures.
Our products for the juice area have been formulated for the temperature range 40°C and higher. Thus they can be used in the following fields:
Raw Juice Area: inlet of cossettes, defoaming systems (e.g. that of the BMA-prescalder), pulp press water systems
Juice Purification: liming tanks, lime milk tanks, carbonations, decanters
The antifoams for the flume water area were formulated for temperatures from 0 up to 30°C so that the main application field in the sugar factory is the whole flume water cycle comprising flushing of beets, beet pre-washing, beet transport and beet washing as well as the beet tail transport and preparation. The dosing is always effected with dosing pumps. Simple diaphragm pumps are sufficient, however a larger nominal width has to be chosen for the suction and pressure lines as well as the valves because of the high viscosity. Low-cost dosing pumps are available for this purpose and can be supplied by us. The necessary dosing rate is quickly and easily determined at site by variation of the dosing frequency.
In case of proper application our antifoams comply with the requirements of the German law for food additives and necessary articles (LMBG) § 11 para 2 phrase as well as with FDA regulation 21 CFR § 173.340.
