Unique Problems Call For Unique Solutions: Cleaning Orange Oil Storage Tank with a 2” Access Hole

A flavoring manufacturer with plants in over 30 countries contacted Gamajet with a challenge. They had hundreds of reservoirs ranging from 125 to 550 gallons that were very difficult to clean. Each tank contained concentrated liquids that provide flavors and fragrances to a variety of products.
The challenge presented to Gamajet was to clean an orange oil storage tank with one 2” opening and no usable drain line. Natural oil products are extremely hard to clean because of the rind fiber inherent with extraction of the flavors/oils. It is very common for potential customers to present the most challenging tank cleaning application to Gamajet. If we can clean the most difficult application in a plant, the easier-to-clean applications are not a problem.
In this case, the most difficult product was orange oil and it was in a tank that was not cleaned in almost three years. The reason the tank was not cleaned more often was due to the difficulty involved. A typical cleaning would take 1-2 days and entailed shoveling/scooping product from the inside of the tank out and approximately 750 gallons of water. Because the tank was fully drained of product, the suspended sediment would clog the lines carrying the product to the production line, thus causing further problems cleaning flexible hoses.
Gamajet chose to use the All-In-One machine as part of a Gamajet Evacublast System. The Evacublast System uses a pressure washer to drive the cleaning head and incorporates a diaphragm pump to extract the liquid out of the vessel during the cleaning process.

The decision was made to run the Gamajet All-In-One for several cycles prior to suctioning out the liquid. This decision was made to help break up hardened crust that developed of a long period of time. This hardened layer could not be suctioned through the Evacublast diaphragm pump.
After a partial cleaning, the vessel was opened up and inspected. The hardened layer had started to break up. Further cleaning patterns were run to continue to break up the hardened upper layer. Over time, the hardened layer broke up into manageable pieces. The decision was made to evacuate the vessel using the diaphragm pump in the Evacublast unit.

After the vessel was evacuated, there was still some residual debris that was not removed. Some of the debris was stuck to the walls of the vessel from long periods of time without cleaning. A final cleaning cycle needed to be run to remove the final amount of debris from the vessel.
This unique application required a unique solution. Gamajet drew from its extensive history in the wine industry to propose a truly unique solution for this customer. The All-In-One was developed several years ago in response to the wine industries need for a machine that could clean wine barrels with the bung (opening) facing up. The All-In-One unit and the subsequent All-In-One Flex unit were developed so barrels would not have to be moved for cleaning. The All-In-One unit typically has a rigid pipe extension as a suction foot while the All-In-One Flex unit has a flexible hose for hard to reach openings. By combining the upper portion of the All In One, the cleaning head was able to extend further into the vessels. The flexible hose foot of the All-In-One Flex unit allowed easy entry into difficult to reach access points.
