Here it is June already, and before you know it your fruit will be ready to be stored. We at Tuff Automation hope you have a great season with few problems, and we’d like to remind you that it is this time of year, when you have access to your controlled atmosphere (CA) storage rooms and equipment, that you should be tuning up your systems. To make this process a little easier for you, we’ve compiled a list of some things you can do to make sure your systems are in top condition and ready to store the fruits of your labors—pun completely intended. Read on for tips regarding some key points of CA storage system maintenance, starting with checking your CA rooms.
Check all rooms for airtightness
This is a time-consuming process, but one that can pay back in real savings. Airtightness is crucial for your CA storage rooms to operate optimally.
There are a number of issues that can contribute to the loss of airtightness in your CA storage rooms. Remember that not all lift truck drivers are as careful as you are, and leak-causing accidents can happen without your knowledge. Additionally, changes in temperature and humidity over the summer cause floors, walls, and ceilings to expand and contract, creating small cracks and holes.
You know as well as we do that once a room is sealed for the year, it can be almost impossible to fix some leaks. And depending on the size of the leak, you may have to continually supply additional nitrogen for the remainder of the season. So now is the time to check your floors, walls, and ceiling for cracks and holes.
Check room components for function
Just like most equipment, CA equipment does not like to sit around. It may have been months since your room valves, low volume relief valves, emergency glycol traps, temperature probes, as well as room lights and everything to do with the refrigeration have been used.
Now would be a great time to start up the system and make sure everything is working and ready for the fall season. It is a lot easier to make these inspections now while they are not being used rather than when you are loading them with fruit.
Check main equipment for function
Once you have your CA rooms inspected, repaired, and tested, you can move on to the main equipment. Most CA systems consist of a nitrogen generator, a carbon dioxide scrubber, and some form of CA controller.
Carbon Dioxide Scrubbers Most carbon dioxide scrubbers will require a little maintenance and calibration. Monitoring the status of the following components will ensure your scrubber is in good shape.
