Project Description
Sugar Mill Antifoams & Defoamer | High-Temp Foam Control for Cane & Beet
Foam is a major problem in cane and beet sugar processing. It cuts throughput, slows heat transfer in multi-effect evaporators, and causes juice overflow losses. Proteins, saponins, and polysaccharides in the diffusion juice and vacuum pans stabilize foam at high temperature. Controlling it takes non-silicone defoamers that stay stable under heavy organic load.
INVINO® makes EO/PO block copolymers, polyethers, and polyether esters that break foam fast without affecting sucrose crystallization. They stay fully water-soluble through carbonatation or sulfitation, avoid scaling on heat-exchanger tubes, and leave no toxic residue in the process.

Sugar Mill Defoamer Applications & Selection
Turbulence in diffusion juice extraction and beet wash water makes heavy foam that slows percolation. Our fluids knock foam down fast to keep the water circuit moving.
Lime, sulfitation, and carbonatation add bubbles that trap sediment and slow clarification. Low-foam polyethers disperse evenly and stay compatible with flocculants.
Boiling in multi-effect evaporators causes juice carryover and surging that hurt crystal yield. High-temperature grades keep foam down and pans level.
Fast flume transport and utility discharge build surfactant-heavy surface foam. Non-ionic grades scatter quickly to lower foaming and keep flow readings accurate.

Technical FAQ for Sugar Mill Producers
Q: Is your defoamer stable and process-safe for sugar manufacturing?
A: Yes. INVINO® sugar mill defoamers use chemically inert block polyethers that break down into non-toxic segments in downstream waste handling. They give stable, residue-free foam control through the juice loop.
Q: Will the defoamer affect crystallization or sugar yield?
A: No. Unlike un-emulsified silicone oil that disrupts sucrose nucleation and warps crystals, our polyethers and polyether esters (INVINO-105) dissolve fully in water and leave crystals clean, protecting final yield.
Q: Can it withstand high temperatures in the evaporators?
A: Yes. Low-end products separate or hit their cloud point under evaporation heat. INVINO-4000B stays stable in multi-effect evaporators above 120°C without losing foam control.
Q: Does it cause scaling on the heat exchanger tubes?
A: No. The non-ionic polyethers disperse well and do not crosslink into insoluble films, so they prevent organic scale in the evaporator loop and keep heat transfer steady.
Q: Is it suitable for both Cane Sugar and Beet Sugar processing?
A: Yes. Beet juice foams from saponins while cane juice carries heavy proteins. INVINO-103B targets beet saponin foam, and INVINO-4000B handles cane juice.
