Why is dimensioning Controlled Atmosphere machinery so important? We would like to pay a little more attention to this. This mainly concerns the CO2 adsorbers. Optimal CO2 values ​​in a cold store are different for every fruit or vegetable variety. Even for different cultivars and growing locations, they can be different. For example,…

For a long time, lime was used to keep the CO2 level in cold stores under control. Lime has now been replaced almost completely by CO2 adsorbers that work with activated carbon. However, a few still believe that lime is ‘better’ or cheaper. Let’s take a look at this. As an example we…

When it is about long-term storage, the moisture balance in a cold store is crucial. Too much moisture loss leads to weight loss, but also to a product that is less easy to store. The quality of fresh product deteriorates, and in the case of fruit it usually starts to wrinkle. Bringing moisture…

Over the past year, Blue Atmosphere has already paid a lot of attention in its blogs to how its CO2 adsorbers distinguish themselves in the market. We would like to add something to that. In larger projects, where the total CO2 production is higher than 900 kg per day, the total tonnage is…

Your measuring system contains an air pump that draws in samples to check the air composition in your Controlled Atmosphere cold stores. This is done at a flow rate of about 6-7 liters per minute. Many customers wonder why their calibration gas is always running out. This is because most measuring systems use…

Anyone who has been around in fruit storage for some time knows that the capacity of adsorbers has increased over the years. Around the year 2000, the advice was to use 22 kg CO2 per day per 100 tons of Conference pears. This was quickly rounded up to 25 kg. In a few…

It remains a difficult choice: the nitrogen generator. There are several mechanisms of action, but most of them fall off immediately, usually because they are outdated (liquid nitrogen, membrane systems, VSA). The systems that remain are the PSA, Pressure Swing Adsorption and the VPSA, Vacuum Pressure Swing Adsorption. But what are the differences?…

CO2 adsorbers for fruit and vegetable storage have cycles that consist of 2 phases. During the adsorption, CO2 is removed from a cold store with the aim of maintaining the target value. During regeneration, the absorbent is cleaned and prepared for the next adsorption phase. Unfortunately, optimal adsorption and regeneration times fluctuate widely….

Nearly all control systems for Controlled Atmosphere storage are centralized. This means that measuring tubes and wiring for valves and fans must be brought to a central cabinet. This cabinet is tailor-made for the customer. Blue Atmosphere does this differently. Our control system is decentralized, modular and standardized. The control part consists of…

Loss of moisture during storage is an important parameter that partly determines the storage time and quality of vegetables and fruit. In some cases it is, therefore, desirable to actively prevent moisture loss. For many fresh products, and certainly for pome fruit, moisture that has been lost cannot be reintroduced. So, what remains…
