Uses of Mint Oil as a Flavoring Agent

Mint oil is a widely used food flavoring agent. A wide variety of consumable products such as toothpaste, chewing gum, soap etc. use mint oil.

Moisture in Crude Mint Oil

Crude mint oil contains moisture. This moisture removal is necessary before distillation to make the oil totally dry.
Large amounts of water in the oil can cause unacceptable load on the distillation system. Trace amounts of moisture left in the oil leads to quality & shelf-life issues. Industrial scale stainless steel centrifuge is the solution!

Pilot Scale Feasibility Testing

One of the largest producers of peppermint oil contacted Dolphin Centrifuge to perform a feasibility study on their oil. The producer wanted to explore centrifuges as a remedy for their moisture problem.
Dolphin Centrifuge proposed a pilot scale test of their mint oil as a proof of concept. Our bench-top, pilot scale disc centrifuge is ideal for such testing.
Disc stack centrifuges show high liquid/liquid separation efficiency. We processed a 20 gallon customer sample through our test centrifuge.

Mint Oil Testing Results

The customer technician used a ‘freeze test’ to verify the dryness of the separated oil (pure mint oil). He would freeze small volume of the oil in a refrigerator.
Clear oil indicated the absence of moisture in the processed oil. All samples taken from our testing centrifuge were clear post freezing. The customer acknowledged the test to be a success!

Large Scale Production Validation

Based on the pilot scale test, the customer purchased a stainless steel centrifuge from Dolphin Centrifuge. Crude mint oil has no solid contamination. So Dolphin supplied a solid bowl, disc-stack centrifuge for their production. It was a stainless steel, food grade centrifuge made by Alfa Laval.
After the centrifuge installation and initial production, the customer returned to Dolphin. Realized production volume from the first unit was as expected. The quality of oil produced was beyond expectation. Based on these facts, they ordered many food-grade centrifuge units for their entire production volume.
