Abstract
Devices, systems, and methods for transporting or transferring insect pupae in an aqueous solution are described. The system includes a tank containing a solution with insect pupae, a transfer chamber having an outlet at a bottom portion of the chamber, a solution inlet, an evacuation channel, and a depth measurement system. A tube fluidly connects to tank and the transfer chamber. An evacuation device connected to the evacuation channel removes air from the transfer chamber and generates a vacuum therein to draw the solution through the tube into the transfer chamber.
Claims11
An insect pupae transfer system, comprising:
- a holding tank to hold a solution comprising insect pupae;
- a transfer chamber comprising:
- a liquid outlet at a bottom of the transfer chamber;
- a liquid inlet positioned above the bottom of the transfer chamber;
- an air passage providing a conduit between an inside of the transfer chamber and an exterior of the transfer chamber;
- and
- a depth measurement system to output a liquid depth within the transfer chamber;
- a delivery tube having a first end coupled to the liquid inlet and a second end of the delivery tube in fluid communication with the holding tank;
- and
- an evacuation device connected to the air passage to reduce an air pressure within the transfer chamber by removing air from the transfer chamber to cause at least a portion of the solution comprising the insect pupae to move, via the delivery tube, from the holding tank to the transfer chamber.
