High quality insect larvae separation

Rotoshifter Royal Dutch Kusters Engineering

Insect farming - the practice of raising and breeding insects as livestock - is a promising and growing market as a source of protein for animal feed or even food products for humans.

Besides, the larvae can be fed with organic waste. This way, insect farming is also a circular solution. Have a look at our Organic Liquefying Press (OLP) if you are looking for a solution to gain virtually pure organics from waste.

When the insect larvae have reached the desired stage, they need to be separated from the remains of the food and insect manure, the so-called frass. 

That's where our Rotoshifter comes in.

Why the Rotoshifter?

insect larvae purity level

Reaches purity level of up to 99,9%

The Rotoshifter allows larvae separation based on size and weight by combining two proven separation technologies. 

It can reach a purity level of clean larvae ánd frass up to 99,9%.

icon moist level

Handles input moist level of up to 60%

The maximum moist levels of the input  - the insects larvae mixed with frass - could be up to 60%*.

*depending on the species and composition of the frass

Rotoshifter capacity

Capable to customize capacity up to 20 m3/h

The Rotoshifter can process a volume of up to 20 m3 per hour, depending on - and adjustable by - several variables.

Similarly, the purity of the output can be determined.

How the Rotoshifter works

1. The mix of insect larvae and frass is fed through the top of the Rotoshifter.

2. Next, a screw transports them to the Rotoshifter cabin.

3. Here, they are sorted using air- and rotational forces and several drum screens simultaneously.

4. Finally, the clean insect larvae and frass are collected separately at the bottom of the Rotoshifter.

Now the insect larvae can be further processed, and the frass can be used as high-quality compost.

As demonstrated in the videos, the Rotoshifter has no problem handling various species.

Moreover, its customizable settings make the Rotoshifter fit in nearly any insect rearing process.
