Decolourising agent for juice clarification

Ezofix  is a cationic colour precipitant which removes colloidal/dissolved colour from sugarcane juice prior to the separation of mud. It is used at a low dosages and added to the limed and sulphited juice emerging from the juice sulphitor. After addition of Ezofix, the limed and sulphited juice goes through the 'S' Juice Heater where the temperature is raised to about 103^o-104^oC. The flocculant is added at this stage at the entry of the clarifier. The clear juice emerging as supernatant of the clarifier has reduced colour to the extent of 30 - 60% depending on the nature of colour causing substances which finally translates into a minimum of 25 - 30% reduction in colour of sugar produced from this juice.

Decolourising agent for syrup clarification (in refining)

EZOFIX is a highly cationic product effective as a decolourisation agent for syrup clarification in the phosflotation process  and is used at dosages upto 150 ppm of polymer by weight of sugar solids. It is effective in removing most of the colour and also high molecular weight impurities such as starch and dextrane which results in good decolourisation as well as good filterability of clarified liquor. The colour of the syrup through use of EZOFIX reduces as much as 30 - 60%.
The unsulphured syrup is treated with the colour precipitant while it is being pumped to a buffer tank which also acts as a feed tank for the clarifier. The treated syrup is passed through a heat exchanger to raise its temperature to 70^o - 75^oC which is then mixed with phosphoric acid and lime superheat (if needed) in a specially designed flash reactor to create primary flocs.

Flocculant for sugarcane juice clarification

Fiber bond-208 is a high molecular weight anionic flocculant and is non-toxic. It is added prior to the clarification of sugarcane juice and at dosages of 1 - 2 ppm. When applied it results in fast settling of the mud in the clarifier. The addition of Fiber bond -208 to the clarifier promotes drier cakes and increased filter clarity of the muddy juice going to the filter from the clarifier under-flow.

De-foamers / Antifoams

Ezochem's de-foamers are highly effective antifoaming and defoaming agents which spontaneously and continuously removes the foam which occur in internal operations in sugar factories.
Ezochem's de-foamers are developed with a view to reduce surface tension at the liquid to air surface and thus eliminate foam. The type and quantity of de-foamer to be used would depend on the quality of foam, pH of the medium etc., and would have to be determined by laboratory trials.
As they are non-ionic defoaming agents, they are non-saponifiable, and therefore have an excellent long term effect. Their chemical stability ensures that they do not decompose and remain effective even after long periods in the juice. Thus, when Ezochem's defoamers are added at the extraction stage, the defoaming effect of the product continues through the juice clarification and evaporator station.

Antiscalant / Dispersants

C-Neel  antiscalants are phosphorous-free, low molecular-weight polymers, and are non-volatile and practically stable to hydrolysis at the temperatures in question. These polymers inhibits scale formation in evaporators caused due to the presence of hardness components in the sugar juice. The hardness components are generally calcium and magnesium ions in the presence of carbonate, oxalate and sulfate ions. This scale prevents effective heat transfer in the evaporator stages, leading to increased energy costs (based on the sugar obtained).

Biocide

EZOLITE is a product of high potency scientifically formulated for sugar processing. It is a free folwing completely soluble in water and non corrosive to mill equipments.A few parts per million of juice of this microbiocide used regularly eliminates most of the problems due to micro organisms particularly leuconostic bacterium and fungi. It distincyly improves recovery much better than any other disinfectants.
