Entoprot Bioreactor:
Scalable and Automated System to Rear Insect Larvae

Production costs must make sense

Any alternative protein source must compete against mass-produced poultry or pig meat in human nutrition. In the animal feed market insect protein competes against fish meal and soy protein. Entoprot has addressed the process economy challenge by

 

Using black soldier fly (Hermetia illucens) larvae as the preferred production organism. Production is effective due to the short development time, only 12 days from egg to prepupa.
Designing an insect growing device that can be automated with low cost. This is the first real bioreactor for growing fly (Diptera) larvae.
Entoprot feed Developing low-cost feed mixtures. We focus at consistent quality, good process economy, and high productivity. At present, the feed conversion rate is 30% on dry matter basis and our aim is to improve it further with modern biotechnology. Our aim is to be able to provide the most affordable animal protein in the market, i.e. press the price below fish feed.

 

What is special in EntoProt Insect Bioreactor Technology?

Entoprot focuses on easy handling, low manual work and high yield in their bioreactor setup. EntoProt’s unique patent-pending bioreactor design provides advanced properties, which are not available in any other commercial bioreactor systems.

Properties Benefits
Continuous rotating movement of the feed
  • Homogenous conditions providing reliable and representative sampling from any part of the bioreactor
  • Optimal and uniform nutrient and moisture conditions
  • Growth of filamentous fungi and other harmful microbes is minimized

 

Efficient aeration system
  • Bioreactor can run with a high fill volume and capacity
Innovative internal support mechanisms for larvae which allows for extreme efficiency in terms of space usage.

 

  • Larvae are not crushed, a one cubic metre bioreactor can handle up to 700 L content of feed and larvae

 

 

Bioreactor performance and capacity

The Entoprot technology is genuinely scalable; the number of growing devices can be adjusted to the size of the factory. We have estimated that a 100 m2 plant with a monthly capacity of 9 metric tons of dried larvae requires 30 m2 for bioreactors, 20 m2 for egg-laying adults, and 40-50 m2 space for feed treatment and product processing.
