Fish Processing FAQs

  • How does the system work? The systems are based upon patented technology which creates a seal around an object and when a pressure differential is introduced, the object moves.
  • How do you clean the system? Our systems are cleaned using standard food processing cleaning agents and protocols (protein rinse,soap, disinfection) but we take advantage of using specially designed sponges transported through the tube for faster and easier cleaning.  We also have the advantage of being able to completely dry the system which creates an inhospitable environment for bacteria.     
  • Can live fish be transported? Yes, happily!   
  • What size range of fish can be transported? We have a range of tubes to accommodate a variety of sizes and each tube can handle approximately a five kilo size range.
  • Does the transport cause damage to fish? The average pressure in the tube is between 1 and 2 PSI so we can even transport live fish.
  • Can fish go backwards? Yes.   Optimally though, it is preferred that the fish be transported head first due to the orientation of their fins upon exit.
  • Which way do fish exit the tube? A fish will exit the tube in the same orientation it entered. If a fish enters upside down, it will exit in the same orientation.
  • How high can a system transport fish? How high do you want to go? Because we do not have to move a column of water, we have no theoretical limit. 
  • How long? Please see the Specifications.  
  • How do you get fish in the tube? The system entrance operates like a vacuum so when a fish is presented to the entrance, it goes.
  • How fast do fish move through the system? A typical system will move fish between 5 and 10 meters per second.
  • How many fish can be transported per minute? Our standard configuration provides for consistent transport up to 40 fish per minute with instantaneous loads of 60+ per minute. Higher volumes are achievable utilizing larger motors.
  • Do you need to slow fish down at the end of the system? Depending upon the configuration, we have a variety of deceleration designs.  
  • Are there temperature operating limits? The materials used to construct our tubes are rated from minus 60 to 300 degrees Fahrenheit. 
  • Can systems be reconfigured or are they permanent installations? Our standard system is designed to be easily configurable. We can also design permanent installations.
  • What happens if a fish gets stuck? The systems are designed to have a restriction at the entrance so a fish too big can’t get stuck in the tube.
  • Can the tube go in the water?   Our tubes can float. Depending upon application, a protective barrier may be required.
  • How much water is used for transport? Our standard system uses water for lubrication only.  Auxiliary misters can be added if required.   A standard mister uses 9 gallons of water per hour.
  • How robust is the system? Each system has just three moving parts – that’s it.
  • How much power does a system use? Depending upon the quantity, height, and length of transport, our systems generally use between 5-25 kw each.

 

Fish Passage FAQs

  • See our questions and answers about the "Salmon Cannon" - Whooshh Fish Passage FAQ.pdf
  • How does the underlying system work? The systems are based upon patented technology which causes a motive force to be introduced. When a localized pressure differential is introduced, between the front and back of the fish in the Whooshh tube, it moves.  

  • Can live fish be transported?   Yes, happily! They are not in a column of water, rather they are in air for few seconds, depending on the length of the Whooshh transport tube.     

  • What is the size range of the fish that can be transported?  We have a range of Whooshh tubes  to accommodate a variety of sizes.  We have transported fish from <1    kg to >15 kg.
  • Is there any scale loss or damage to eyes? With an average pressure of 1-2 PSI experienced by the fish, our tests and experience suggest there is little to no scale loss and no evidence of damage to their eyes.
  • How high can a Whooshh system transport fish? How high do you want to go?   Because we do not have to move a column of water, we have no theoretical limit. There may be practical limits, but if we have not encountered such project yet.
  • How long? Please see the Specifications.  
  • How do you get fish in the tube? The fish can be hand fed or be part of a volitional entry system
  • How fast do fish move through the system? A typical system will move fish between 5 and 10 meters per second. 
  • How many fish can be transported per minute? Our standard configuration provides for consistent transport up to 40 fish per minute. Higher volumes are achievable depending on specific system configruations.
  • Do you need to slow fish down at the end of the system? If the fish is exiting into open waters, we may not need a deceleration system. If exiting to a confined area, depending upon the configuration, we have a variety of deceleration designs that can be deployed.
  • Are there temperature operating limits? The materials used to construct our tubes are rated from minus 60 to 300 degrees Fahrenheit. Because water is not used in the tube, except as a lubricant, the tube does not freeze and need not be drained. We do mist the tubes, which also cools the air in the tube.
  • What happens if a fish gets stuck? We would never want to see that happen. The systems are designed to have a restriction at the entrance so a fish too big can’t enter the tube in the first place.
  • Can the tube go in the water? Our tubes can float. Depending upon application, a protective barrier may be required.
  • How much water is used for transport? Our standard system uses water for lubrication only.  Auxiliary misters can be added if required. A standard mister uses 9 gallons of water per hour. 
  • How robust is the system? Each system has just three moving parts – that’s it.
  • How much power does a system use? Depending upon the quantity, height, and length of transport, our systems generally use between 5-25 kw each.

 

Fruit Harvesting FAQs

  • How fast does the fruit move through the whooshh tube? About 15 feet per second.
  • How wide is the harvester? 7.5 feet at the base. 5.5 feet in the middle. 3 feet at the top. We designed the harvester to work in almost any orchard configuration. See the Full Specifications.
  • What are your productivity gains? This is a tricky question! The total economic gains achieved can be significant - more than 50%. How fast do your pickers pick in each of your orchards when measured in FPMS (Fruit Per Minute Sustained)? How many support staff did you use to achieve that sustained rate? How many managers and how many times did you have to handle the same piece of fruit? Making the entire harvest process more efficient is the goal of the PickerTECH MHS, but the answers to these questions ultimately help to calculate the gains.
  • How long are the tubes? The Whooshh fruit tubes are modular. They come in 10 inch (25 cm) sections and then clamp together end to end to increase the length. A typical tube length would be 12 - 24 feet (4 - 8 meters).
