What is SRS?
The Solids Recovery System, manufactured and designed by our Partner Sati, is an equipment that is installed with the aim of recovering all the by-products that are generated during the extruding, screening, drying and cooling processes; recovers both the highly unstable product due to its high humidity that is generated at the start of the extruders, as well as all the fines that are generated in the subsequent stages. According to studies carried out, between 1.5 and 3% of by-products are generated, in some cases reaching values of up to 5%.
The main advantages of the SRS are:
1- Save costs and re-process times
2- Optimize the manufacturing process
3- Recovers wet and dry products
4- Improve traceability
5- Achieve homogeneity
As can be seen in the image below, the equipment has two stainless steel tanks (which comply with FDA and EHEDG standards), one of which is where the homogenization process of the by-products is carried out and the other is where the mixture is kept in motion and then injected into the extruder's pre-conditioner.
An important and necessary aspect that we must clarify is that the solids recovery process is fast, so it does not lead to the decomposition of the material (mainly when it comes to wet extruder starts and stops).
The Solids Recovery System is a 'Proven Solution' and the best way to reuse in a Safe and Controlled way all the by-products of the Extrusion process in the Manufacture of Pet Food as well as in the process of Aqua Feed and Animal Feed.
