If your freezer has a high humidity level, it could be due to too much warm air coming in during the summer months. Dehumidifiers and air conditioners can be used to lower the humidity. The humidity level in freezers and walk-in coolers should be kept between 60 and 75 percent.

Refrigeration is a specialist refrigeration function
There are many applications in refrigeration. It is essential to cool water during processing in order to prevent the growth of bacteria and lower energy costs. For cheese processing, the water temperature in dairy operations must be between 50-68degF/10degC.
Humidity is reduced by air conditioners and dehumidifiers
A dehumidifier and an air conditioner can help reduce humidity around a freezer. These machines convert moisture in the air to water. Water is then pumped out of a room via a drainage pipe. They must be used when the temperature is below 10degC.
Dehumidifiers can speed up the drying process, although natural drying is always best. You should remember that drying times can vary depending on the airflow through your home. Over-drying can cause premature flaking or cracking.
Designated vegetable and fruit drawers keep produce fresher for longer periods of time
You can store produce more efficiently by having designated fruit and vegetable drawers in the freezer. The key is to store produce in a humidity-controlled drawer that is set to the right level for different types of produce. You can read your fridge’s user manual to determine the proper humidity levels for different items. Generally, vegetables should be stored in high humidity drawers while fruits should be stored in low-humidity drawers.
Always buy the freshest produce possible when you are buying it. Leafy greens should be vibrantly colored with no yellowing or limp leaves. The same applies to root vegetables. Avoid soft spots and blemishes. This will reduce the shelf life of your produce. Also, try to pick up produce that is heavy for its size so that it can last longer in your freezer.
It is important to maintain a humidity of 60-75 percent in freezers and walk-in coolers
High humidity is caused in part by the presence of water vapor in the atmosphere. While humidity is always present, certain areas are more susceptible to high humidity than others. For example, opening and closing walk-in cooler doors causes warm air to rush into the cooler, raising the humidity level. This means that the compressor needs to work harder to lower the temperature and keep the unit at the desired 60 to 75 percent humidity. Although a higher humidity level is not dangerous, it can make a walk-in cooler or freezer less efficient.
Maintaining the correct humidity level is essential for the preservation of food. For example, meat and fish need to be kept at about 85 to 90 percent humidity, but fresh fruit and vegetables need to be kept at a higher temperature. Food that’s too hot or too cold will dry out and shrivel.
