Amritsar district has two sugar mills: Rana Sugars at Buttar Seviyan, which started crushing in 1993 with a capacity of 2500 TCD that was later expanded to 5000 TCD, and Ajnala Cooperative Sugar Mill at Bhala Village, which crushes 25,000 quintals per day. Both mills are running through a difficult season. Punjab's cane yield fell from the normal 340 quintals per acre to around 300 quintals after flood damage, and mills across the state are struggling to secure enough cane to run at capacity.
When cane is scarce, the cost of losing sucrose anywhere in the process becomes harder to absorb. That is the context in which sugar process chemicals matter. They are not a single product but a set of interventions at different stages, each targeting a specific loss mechanism.
At milling and juice extraction: Cane that has waited longer between harvest and crush carries higher microbial loads. Bacteria convert sucrose to dextran and other polysaccharides, which not only reduces recovery but also raises juice viscosity and complicates downstream processing. Biocides applied at the milling tandem target this microbial activity before it does irreversible damage.
At clarification: Juice carries suspended colloids, soil, and soluble impurities. The clarification stage uses lime, heat, and polymers to separate these from the clear juice. Coagulants and flocculants work together here: the coagulant destabilizes the colloidal charge, and the flocculant bridges the particles into flocs that settle in the clarifier. The goal is clear juice with minimal sucrose carried into the mud.
At evaporation: Clarified juice is concentrated by removing water in multiple-effect evaporators. As the juice concentrates, dissolved salts become supersaturated and deposit as scale on the tube surfaces. Scale is an insulator. It reduces heat transfer, forces the evaporator to work harder, and can eventually force a shutdown for cleaning. Antiscalants and scale softeners intervene at this stage to keep the tubes clean.
At crystallization: The concentrated syrup is boiled in vacuum pans to form crystals. Massecuite viscosity affects how well the crystals grow and how easily they separate in the centrifuge. Viscosity reducers are used to improve massecuite fluidity, which can shorten boiling times and improve crystal uniformity.

The cane shortage changes the economics of chemical selection. In a normal season, a mill might accept a certain level of sucrose loss in filter cake or a certain frequency of evaporator cleaning because the throughput makes up for it. In a short season, every quintal of cane has to deliver more. A biocide that reduces dextran formation, a flocculant that releases more sucrose from the mud, or an antiscalant that keeps the evaporator running at design capacity all contribute to the same goal: more sugar from the cane that is available.
The selection still depends on the specific mill. Rana Sugars and Ajnala Cooperative have different equipment, different juice profiles, and different operating practices. A chemical programme that works for one may need adjustment for the other. The starting point is always the mill's own data: juice analysis, evaporator performance, and clarification results.

Q: Which sugar mills in Amritsar district use process chemicals?
A: Amritsar district has two verified sugar mills: Rana Sugars at Buttar Seviyan, with an initial capacity of 2500 TCD expanded to 5000 TCD, and Ajnala Cooperative Sugar Mill at Bhala Village, with a daily crushing capacity of 25,000 quintals. Both mills use process chemicals at clarification, evaporation and crystallization stages.
Q: What chemicals are used at each stage of sugar processing?
A: At milling and juice extraction, biocides control microbial growth that causes sucrose inversion. At clarification, coagulants and flocculants settle impurities. At evaporation, antiscalants prevent scale on tube surfaces. At crystallization, viscosity reducers improve massecuite flow. Each stage has different chemistry requirements.
Q: How does the cane shortage in Punjab affect chemical selection for Amritsar mills?
A: Punjab's cane yield fell from about 340 to 300 quintals per acre this season due to flood damage, and mills are under pressure to maximize recovery from available cane. This puts more emphasis on chemicals that reduce sucrose loss, such as biocides that control inversion and flocculants that minimize sucrose in filter cake.
Q: What is the difference between a coagulant and a flocculant in sugar clarification?
A: A coagulant, such as Polydadmac, neutralizes the surface charge of colloidal particles so they can come together. A flocculant, such as an anionic polyelectrolyte, bridges the destabilized particles into larger flocs that settle faster. The two work at different points in the clarification sequence.
