OPTIMIZING BSF PRODUCTS

\n\n\n\n

Black soldier fly processing offers many options. The final solution depends on whether you are starting with a pilot farm or expanding into a commercial BSF operation.

\n

At Insect Engineers, we understand the importance of supplying turnkey BSF farms. We know it can be difficult for customers to access all the right knowledge.

\n

That’s why we ensure you can rely on our expertise and experience. On this page, we explain the different possibilities available for processing BSF products.

BLACK SOLDIER FLY LARVAE SIEVING

\n\n\r\n\r\n\n

After harvesting the ZOEM rooms, black soldier fly larvae need to be separated from the remaining substrate (frass). On a commercial scale, this is done using multiple-step sieving. The first sieve should achieve the best possible result, and some customers even manage a 100% separation.

\r\n

Experienced operators know that sieving can be challenging. There is no single method that always works perfectly.

\r\n

For this reason, Insect Engineers developed a multiple-step sieving system. In addition, steps two and three provide extra assurance of a proper product. On the other hand, this solution may be overkill for a small-scale BSF farm. Nevertheless, it is recommended as the standard for commercial operations. Therefore, commercial farms can benefit from higher product quality and consistency.

BSF MEAL + BSF OIL

\n\n\r\n\r\n\n

After sieving you have different directions you can take. One direction is producing insect meal and insect oil. In most situations we first dry the larvae and afterwards the dried larvae are processed in a BSF screw press to make insect meal and insect oil. We can deliver this on pilot and large scale. Picture shows pilot scale setup.

INSECT PASTE

\n\n\r\n\r\n\n

Most often the feed milling companies require a dry product. When it comes to pet food it can be different. They are often looking for a product with a certain moist content. For that reason, making insect paste from the BSF is ideal. As you don’t need any drying, which saves cost. You can directly grind the fresh larvae into a paste. That BSF paste can be sold to pet food feed mills.

INSECT FRASS

\n\n\r\n\r\n\n

Frass is a great fertilizer for agricultural grounds and plants. We could talk for hours about this great topic. You want to know more, look at this fact sheet from IPIFF. https://ipiff.org/wp-content/uploads/2021/11/Nov-29-2021-IPIFF-fact-sheet-on-insect-frass-final.pdf

INSECT FRASS DRYING

\n\n\r\n\r\n\n

How can you dry and/or pasteurize frass in an efficient and economical way? This can be done by combining technology with the natural benefits of composting.

\n\n\r\n\r\n\n

The Insect Engineers frass drying tunnel works with the following steps:

\n\n\r\n\r\n\n
    \n\n
  1. With pipes in the ground air will be blown through the frass.
    2. \n\n\r\n\r\n\n
  2. The air will bring oxygen in the frass, and this will start a composting reaction in the frass.
    3. \n\n\r\n\r\n\n
  3. Temperature will raise to 60 to 75 degrees Celsius.
    4. \n\n\r\n\r\n\n
  4. Because the temperature raises more water will be evaporated.
    5. \n\n\r\n\r\n\n
  5. The frass dries.
    6. \n\n
