Cold Storage

Product Details:

The quality of onion, and its storage life, is reduced by the loss of moisture, decay and physiological breakdown. These deterioration are directly related to storage temperature, relative humidity, air circulation and gas composition. In an attempt to attain the desired storage condition in an enclosure, many systems have been developed over the years with intense research work by our design engineering.

Good storage should prevent excessive loss of moisture, development of rots, and excessive sprout growth. It should also prevent accumulation of high concentration sugar in onions. Temperature, humidity, co2 and air movement are the most important factors during storage.

Onions can be stored at two ranges of temperatures.

1. Between 0 and 4° Celsius
2. Between 25 and 31° Celsius

The gastight building concept. What is the idea behind a ULO storage?

Creating optimum conditions in the coldstore to preserve the fruit longer so that the consumer can enjoy fresh fruit with a great taste all year round.

What is an Ultra Low Oxygen cell exactly?

In simple terms a ULO storage is a gastight coldstore constructed from high quality insulated panels.Lowering the oxygen level and raising the CO2 value is called controlled atmosphere storage. Storage at an extremely low oxygen level is called ULO storage. During storage fruit 'breathes' using oxygen & producing ethyleen or carbon dioxide.The situation in the ULO cell depends on the type and variety of fruit and can be as follows:
refrigeration with temperatures ranging from -2ºC to 5ºC

reduction of the oxygen level to 1.2%

increase of the CO2 value up to a maximum of 4%

These conditions are controlled by the following process:

at least three times a week samples of the cell air are taken using a measuring and control unit in order to determine the respiratory quotient (RQ) and to correct the oxygen level automatically if required.
- If the oxygen level is too low an aeration fan switches on. If the oxygen level is too high
CO2 is sprayed into the cell using a CO2-scrubber.
- If the CO2 level is too high the CO2 scrubber is activated which removes it from the air in the cold store.
After the harvesting it is recommended that fruit is stored at high relative humidity of 90-95% in order to limit dehydration as much as possible.The entire process ensures that the respiratory process of the fruit is slowed down.This CA or ULO storage process is also known as putting fruit to sleep.

Sleep via Controlled Atmosphere & Ultra Low Oxygen

After fruit like apples and pears has been harvested you can usually store it for a week.Refrigeration extends the life by a maximum of two months.If ULO and CA technology is used we can extend it even further.It means that the fruit scarcely breathes at all & can be stored for 6 to 12 months.Controlled Atmosphere allows us to raise the CO2 level if desired.

Coma via Dynamic Controlled Atmosphere (DCA)

Applying a Dynamic Controlled Atmosphere (DCA) makes it possible to keep the fruit even longer.This is achieved through continuous measurement of oxygen and CO2 values among other things as well as alcohol as an indicator of imminent fermentation so that this can then be controlled automatically.Oxygen percentages of less than 1% are not uncommon.No chemical substance is used at all.Another sustainable advantage of DCA is that you can save around 20% in refrigeration costs.This is because when the apples and pears are in a coma they generate less heat than when they are asleep.

Physical dangers and safety measures for ULO cells
Dangers:
Danger of suffocation
Danger of falling from the top of the ULO cell through the inspection hatch
Safety measures:
Clear warning sticker in several languages
Light signals
Barred openings behind gastight inspection hatches
Special locks on the gastight entrance doors

Do you have renovation or building plans for a ULO cell?

The basis for optimum condition in a ULO cell is the objective of 100% gastightness of the cell.Sigma Projects has developed the gastight building concept for this purpose.For applying this concept Sigma uses high quality insulated panels to build the coldstore.The precise fitting of the insulated panels & vapour-proof construction details guarantee a vapour-proof construction with optimally fitting joints.We give the coldstore a vapour-proof finish on the ‘warm’ outside.Careful sealing and gastight coating on the inside of the joints profiles ducts for pipes and finishes of the corners in walls and ceilings take care of the rest.
