The market price for fruit and vegetables is primarily determined by quality, supply and demand. But how do you maintain the best quality in your products until the most suitable moment? Simple: by opting for storage under Controlled Atmosphere (CA) conditions. By using CA, the physiological processes in the stored product are slowed down, resulting in an extended storage life. The product is put into hibernation so to speak. The required conditions are achieved by creating and maintaining a special protective atmosphere. Lowering the oxygen level slows respiration and reduces the metabolism of important nutrients. The aim is to keep the oxygen level as low as possible in order to preserve these nutrients – hence quality. The remaining oxygen is converted into CO2, which in turn ensures that the respiration of fruit and vegetables is further slowed down. However, excess CO2 will damage your product and must therefore be removed. Ethylene is produced by fruit and vegetables and stimulates the ripening process – hence the ageing process. In order to slow down these processes, it is necessary to remove this harmful ethylene gas from the air of the cold stores for some products. Each product variety requires different conditions. Depending on factors such as climate, weather, soil conditions, growing conditions and the time of picking, the optimum conditions vary not only year by year, but also from one product to another and even from one variety to another. As experts in CA storage, we offer you tailored solutions and every opportunity to keep a close watch on your valuable produce. These days, many different storage concepts are available: ULO, DCA, ILOS, DILOS, DCE, etc. Besseling can supply both the protocols and the required equipment for these concepts.
PALLET FRESH SYSTEM
Soft fruit, a great product but also a sensitive one. It is a product that must be marketed at the right moment in order to fetch the best price. Especially for these sensitive fruit varieties Besseling has developed the Pallet Fresh System. This storage system enables you to store your products under CA conditions per pallet/cover in order to maintain their quality for as long as possible. Particularly for smaller quantities, the Pallet Fresh System is the ideal solution. Various types of fruit and vegetables are stored in a product-specific atmosphere per pallet immediately after harvest in order to supply the highest quality and the correct quantity on demand. Flexibility is important; single or multiple pallets can easily be removed or added to the system without affecting the conditions of the other pallets. The Pallet Fresh System works both with individual pallets or groups of pallets, depending on the quantity and the variety of the product that needs to be stored. Each Pallet Fresh Unit consists of a cover and a special pallet on which the crates, boxes or even a pallet with products can be placed. Also required are:
A cold store
Measurement and control system (ACS) for creating and managing the CA conditions
Nitrogen from a Besseling PSA nitrogen generator
CO2 from gas cylinders
Oxygen from an air compressor
Softripe® is completely different from conventional fruit ripening systems. While traditional ripening systems require a fixed ripening program, softripe responds to the needs of the fruit. The fruits (e.g. bananas or avocados) are in a gastight, closed chamber. Through continuous measurement of the gas concentrations in the chamber (oxygen (O2), carbon dioxide (CO2) and ethylene (C2H4)), the physiological state of the fruit is determined by means of the respiratory activity (change of the values). Through this "communication", the optimum ripening conditions of the fruit are dynamically calculated and adjusted. The air temperature and the O2, CO2, C2H4 concentration in the chamber are permanently controlled. The fruit determines the required state of the atmosphere. By automatically setting the desired parameters, it is able to ideally ripen "stress-free".
CONTROLLED ATMOSPHERE DISINFESTATION
Insects are a pest for commodities. By decreasing the level of oxygen in a gas tight, temperature controlled store a mortality rate of 100% can be achieved. This treatment is lethal, non-toxic and does not have a negative influence on the treated product itself. Controlled Atmosphere disinfestation is suitable for;
and many other commodities.
The efficacy of the treatment is depending on physical factors such as gas concentration, temperature and relative humidity. There are also biological factors such as insect species, strain and development stage. Besseling masters these conditions and can help you in design and implementation of the essential components.
Fire, the nightmare of every business. There is no sadder sight than the smoldering remains of what used to be your storehouse or archive. Of course you take precautions. You store flammable materials separately and of course you have fire extinguishers to hand. However, danger is never far away… Unless you remove the most important factor: oxygen. Without oxygen, a fire simply cannot get started. By reducing oxygen to a level at which combustion is impossible – a perfect and proven alternative to sprinkler systems and/or compartmentalization of large storage facilities. Examples are:
Freezer and cold storage facilities
Telecommunications and computer rooms
Storage of hazardous substances such as fireworks, ammunitions, gas cylinders, etc.
Archives & museums
The Besseling PSA nitrogen generator combined with a measurement and control system (ACS) is the perfect solution. The measurement and control system also provides the required level of safety thanks to alarms based on thresholds which can be set by the user.
Our products are also used for other applications, for example:
Simulated altitude training
Inflating car tyres
In the production process of breweries
Blanketing of tanks and pipelines in both horticulture and the petro-chemicals industry
Actuating of pneumatic systems
In SMT, wave soldering & SMD assembly
There are numerous other possible applications for our products. If you would like to know how Besseling can help you in your production process, please contact us.
