INCORPORATING COLD CHAIN the airflow in the correct way , you are fighting a losing battle . And you can do what you want , but you ruin your cooling process and your commodity quality .
Secondly , and linked to the above , air cannot go through a wall , all it can do is blow the wall over . Simple . Always .
Thirdly , if you design a forced aircooling system where you want to cool your product and use almost-blocked cartons , you will have problems . Not only problems that manifest themselves in far longer hours to cool your product properly , but also discrepancies in temperature between the air receiving side of the pallet and 1 200mm later where the air is supposed to go out after having cooled your product .
Fourthly , due to the non-conformity of an approved airflow system , the use of various carton manufacturers ( 8 or more ), all with another differing ‘ vent-system ’ and the use of big co-operative massive cold rooms with various pallets , tunnels , and temperatures in ‘ one system ’, you create such a parameter variation equation that even Albert Einstein would not be able to solve it .
Fifthly , there is almost NO vertical airflow to keep the pallets on temperature in the container .
So , in doing the above you create a long list of problems :
• Longer cooling hours
• Difference in temperatures in different places on the pallet , creating condensation
• Problems in cooling times
• Colder fruit boxes , which were ready earlier , standing unnecessarily long in tunnels
• Condensation in bags and problems with SO2 pads in the case of Table Grapes
• Problems in transport as containers will balance discrepancies in pallet temperature creating condensation again
• Drying out of fruit with steri process
• Unnecessary high wind speeds with too low relative humidity creating drying out of fruit in the process
• Steri process that hammers the quality due to the not handling and preserving the quality after harvest properly
The answer my friend , is blowing in the wind . It is so obvious that people simply look over it . Go to the root cause analysis system and tackle the problems at the source . Agree on a uniform airflow system for all manufacturers so that when various pallets come in a humongous cooperative tunnel system , at least the airflow is uniform .
And get it for once and forever through flow friendly for Pete ’ s , and everybody else ’ s sake .
It is rather simple . Just do it ! And you do not need to wear a certain brand of shoes either .
Trying to cool a pallet of sold bricks in a uniform and equal way is impossible . This is exactly the same principle for airflow in regards to incorrect carton box designs .
*’ Blowin ' in the Wind ’ is a song written by Bob Dylan in 1962 , and released as a single and included on his album The Freewheelin ' Bob Dylan in 1963 . It has been described as a protest song , and poses a series of rhetorical questions about peace , war , and freedom . The refrain " The answer , my friend , is blowin ' in the wind " has been described as " impenetrably ambiguous : either the answer is so obvious it is right in your face , or the answer is as intangible as the wind ".
In 1994 , the song was inducted into the Grammy Hall of Fame . In 2004 , it was ranked number 14 on Rolling Stone magazine ' s list of the ‘ 500 Greatest Songs of All Time ’. Source : Wikipedia
