High-Quality Black Soldier Fly Larvae and Frass Separator

 

Worldwide we experience a growth in farming Black Soldier Fly Larvae. Farming these insects for animal or human consumption can be a viable alternative for traditional agriculture.

Insect agriculture implies lower greenhouse emissions, so a lower impact on the environment. Also it requires less resources and extensive land use than the known energy and agricultural land requirements for obtaining conventional animal protein.

The Rotoshifter – An alternative to sieving

 

Farming Black Soldier Fly Larvae (BSFL) in a closed or indoor environment is an important means to making food available continuously year-round, since many insects are available in nature only during certain seasons or months. Mealworms and Black Soldier Flies are quite popular insects to breed with.

The farming of BSFL can be a circular solution and can be promising as well to manage the growing amount of organic waste! This is because the larvae can transform any kind of organic waste into high-quality protein. And they can be used to feed animals. But before they can be feed they first need to be separated from the frass.

MANUAL VERSUS AUTOMATED SIEVING

Would you also like to get a more efficient process to separate the larvae from the frass?

Manually harvesting Black Soldier Fly Larvae (BSFL) can be very time consuming and requires the presence of one or more operators. Moreover, it is impossible to reach the same shaking frequencies as automated shaking sieves. The mesh size of the sieve should be smaller when manually sieving, which means it takes even more time to separate the frass from the larvae. Even more so, sieving can require multiple sieving steps.

Finally, moisture can cause separating problems when sieves clough up and could even require a different separating method.

ALTERNATIVE TO SIEVING

The Royal Dutch Kusters Engineering Rotoshifter separates BSFL using air- and rotational forces and several drum screens simultaneously. This system combines two proven technologies into one, ensuring the larvae are efficiently separated from the frass.

Seven features of the Rotoshifter technology:

✔  Effectively separates larvae and frass
✔  Capacity and purity of output adjustable
✔  Separation efficiency up to 99.9%
✔  Available in various models (throughput capacity 0.5-20 m3 per hour)
✔  Low energy consumption
✔  Minimize loss of larvae in frass
✔  Remove skins and dead larvae

HIGH PURITY LEVEL AND CUSTOMISABLE CAPACITY

The Rotoshifter reaches a purity level of clean larvae of 97.5 to 99.0%, assuming the systems’ variables are optimized for purity. Moreover, the maximum moist levels of the mix of BSFL
and frass could be up to 60%*. The purity level of the frass could be up to 99.9%.

The throughput capacity can vary from 0.5 up to 20 m³ per hour, depending on the diameter and the length of the Rotoshifter. It’s settings can be customised which makes the Rotoshifter fit in nearly any insect rearing process.

Besides, Royal Dutch Kusters Engineering can also provide a system to optimize the feed efficiency of the larvae. The Organic Liquefying Press separates organic waste from other (inert) materials to gain virtually pure organics.
