01Origin
Engineered from inside a working BSF plant
We designed it in our own plant, between shifts of filling, stacking and washing. Every dimension answers a task we do every day.
engineered for insect farming
LarvTech · Industrial insect rearing tray
LarvBox. The industrial BSF tray designed by people who produce BSF.
02Cycle
Engineered for optimization of every cycle, 52 times a year: hundreds of handling operations per tray
- 01Filling
- 02Seeding
- 03Growing
- 04Moving
- 05Harvest
- 06Washing
- 07Ready again
Every 7 days the same tray is filled, seeded, grown, moved, harvested and washed. That is 416 handling operations per tray per year; every second it saves is repeated in all of them.
03BSF
Engineered for BSF and ready for mealworm
Smooth walls and a continuous floor so the substrate spreads evenly and comes out in one piece at harvest. More usable height than the standard 145 mm tray: more substrate and more larvae every cycle, on the same footprint.
04Stacking
Engineered to stack straight on the pallet, no racks
When full, each tray leaves the one above the air the larvae need. Five stacks per US pallet.
- 17 high in manual operation
- Up to 24 in automated facilities
05Stability
Engineered for stability stacks that stay closed when moved
Four seating points in the corners lock each tray onto the one below. The stack moves on the pallet truck as a single block.
06Cleaning
Engineered for cleaning fewer corners, less washing time
Wide inner radii and surfaces the water can reach. A few seconds saved per tray add up to hours every month.
- No corners for substrate to stick
- Polypropylene up to 100 °C*
07Nesting
Engineered to nest turned 180°, one drops into the other
Empty, it turns half a turn and drops into the tray below. The same 17-tray stack takes far less space in the truck, in storage and in the wash area.
- From 2.65 m to 0.59 m
- −78 % height when empty*
08Automation
Engineered for automation grippers, robots and automatic washing
The openings in the short ends are designed for a gripper to reach in and lift the tray. It works with different grippers and lines: robotic stacking and destacking, conveying and automatic washing.
- Gripper through the end-wall openings
- Being robotised in our own plant
09Growth
Engineered to scale from the first room to the full plant
The same tray works in manual, semi-automated and robotic facilities. The trays you buy today still work the day you automate.
- Manual
- Semi-automated
- Robotic
10 · Detail
Every detail answers an operation.
Seating points
They centre the upper tray and keep the stack from shifting when it moves.
Wide radii
Rounded internal corners where residue has nowhere to stay.
180° turn
The same part stacks one way and nests the other.
Grip zones
Rigid short ends for the operator's hand and for the robot gripper.
