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.

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

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.

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

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.

We are actively engaged in offering Cold Storage Consultation. Our offered service is high on demand in various food industries due its effective preserving & storage. These services are carried out by experts of this work & before execution go through with all the need of customers in order to provide best services.We already guided over 340 cold storage project with 43 years of practical experience. 

With this Storage Control set you have 5 wireless logger which you can put in your (cold) storage. It measures the critical parameters for potato storage and provides a realtime overview for monitoring conditions during the storage season. You can even put in alarms if a measurement exceeds certain tresholds!
But it doesn’t end here; This can be used also in the field during planting. By placing multiple devices in different locations of one field you can check temperatures, soil moisture and CO2 levels more closely than traditional sensors. One device does it all!
It is the perfect (wireless) monitoring tool for your storage facility. But it’s not just a passive data logger. It can actually transmit real-time measurements by air, utilizing wireless technology. Data is automatically uploaded to the cloud and can be monitored at any time using the product Portal. Here you can review gathered information and a history of previous measurements. You can also set up alarms if a measurement exceeds certain allowed tresholds.
Features:
Installed in the storage facility to monitor:
 
Temperature
Relative humidity
CO2 level
Mechanical shock
Soil moisture
The complete storage monitoring system for every size storage facility!
