Clean-in-Place (CIP) Chemistries for Ethanol Producers
What is clean-in-place (CIP)?
Clean in place (CIP) is a cost-effective and efficient method of cleaning equipment as it eliminates the need for disassembly and reassembly, which can be time-consuming and costly. It also reduces the risk of contamination through a closed cleaning process with no exposure to the environment.
WHY IS AN EFFECTIVE CLEAN-IN-PLACE (CIP) PROCESS IMPORTANT IN ETHANOL PLANTS?
During the production of biofuels, various equipment and pipelines are used to handle raw materials like corn or sugarcane, as well as the chemicals and enzymes required to break down these raw materials. Over time, residues from these materials can build up creating a breeding ground for bacteria and other microorganisms.
If left unchecked, these microorganisms can contaminate the ethanol and compromise its quality, as well as create blockages that result in equipment downtime and lost production. An effective CIP process is essential to removing these unwanted solids and bacteria.
Hydrite Hydri-Maize™ Clean-in-Place (CIP) Products
We offer a wide range of CIP products including caustic replacement, acid cleaning, hydroxyl-free radical cleaning, and other scale inhibition and scale removal products. Our formulations decrease downtime while increasing corn oil recovery and could improve water balance.
All products are FSMA compliant and GRAS for animal feed.
Traditional CIP vs. Hydrite Hydri-Maize™ CIP – Faster & More Effective
Time is money and keeping your ethanol equipment online is critical to maximizing production. By using the Hydrite Hydri-Maize™ CIP product line, ethanol processors can cut their downtime in half:
Hydri-Maize CIP (HC2759)
A highly-concentrated acid & chelator liquid formulation designed to replace sulfamic acid crystals, Hydri-Maize™ SAR is effective in removing inorganic and organic compounds in ethanol plants. Benefits include:
- Enhanced employee safety through elimination of powder handling
- Fast and accurate dispensing with a pumpable liquid
- GRAS for animal feed and FSMA compliant
- Easily adapted to existing operations
- Simple to operate
Injected into evaporators to prevent scale formation and improve heat transfer, Hydri-Maize™ Scale Control 200 is a high solids liquid chelating agent for sequestering mineral ions in bioethanol production. In a year-long study against a competitive product, Hydri-Maize Scale Control 200 significantly reduced evaporator pressure (Psig) at an ethanol plant. Benefits include:
- Increased corn oil recovery
- Proactive triple action scale prevention through chelation, dispersion, and threshold inhibition
- Reduced sulfuric acid consumption
- Improved water balance control
A proprietary, alkaline cleaner that solubilizes fats and removes soils, Hydri-Maize™ General Cleaner is specially formulated for ethanol plants to meet feed requirements. It can be used straight for heavy soils or can be diluted 5-15% depending on the job. Benefits include:
- Lowered overall chemical spend
- GRAS for animal feed
- Removes both inorganic and organic soils
Used as a descaling agent in CIP tanks, Hydri-Maize™ 2759 can be injected into evaporators to remove protein and mineral scales. This powerful liquid solution can be completed in a single shift, reducing or eliminating the hydro-blasting step. This means the evaporator CIP process can be completed in 3-5 hours instead of the typical 8-20 hours of downtime. Additional benefits include:
- Increased corn oil production
- Improved heat transfer
- Fewer chemicals required
- Less water consumed
Hydri-Maize™ Evap 200 is a specially formulated additive used to remove mineral scales like calcium, magnesium carbonate, phosphate, and oxalate during the alkaline wash of thin still evaporators. This phosphate-free liquid formula uses food-grade materials and is easy to add to the evaporator wash cycle.
