SUCCESS IS … MAKING THE BEST OUT OF EVERY PROCESS Flottweg centrifuges are used in various processes for processing offal. Depending on the process, throughputs between 0.5 and 25 t/h (decanter) or 0.5 and 12 t/h (separator) can be processed. Flottweg decanters are used in 2-phase processes, Flottweg Tricanter® in 3-phase processes. Disk dryer Screw press Solids ® = registered trademark in different countries.

There are basically two different processes: Either a disk dryer (see previous page) or a vacuum dryer (see below) is used. Vacuum dryer (Anderson) Flottweg decanter Solids Screw press Water/solids Mill Flottweg separator Meal shipment Storage tank

PROCESSING PROCESSING OF OF ANIMAL ANIMAL BYPRODUCTS BYPRODUCTS 01 In the 3-phase process at high temperature In contrast to the 2-phase process, the product is separated in the first step before the individual streams are dried or evaporated.

The low-temperature process is mainly used in the processing of category 3 material (poultry offal), but also in smaller fat rendering applications.

PROCESSING PROCESSING OF OF ANIMAL ANIMAL BYPRODUCTS BYPRODUCTS In fat rendering, the byproducts of slaughter that are suitable for further use as food, such as rinds, are processed. There are basically two options for process control when processing these byproducts. Traditionally, after comminuting and heating the product, decanters are used in the first separation step to separate the greaves. In the second work step, the liquid phase is separated from the decanter into the constituents fat, stick water and solids by means of disk stack separators. Usually, the fat phase is clarified with...

DEWATERING DEWATERING COAGULATED COAGULATED ANIMAL ANIMAL BLOOD BLOOD Animal blood is an important product for the feed industry. In addition, the processing of animal blood into blood meal offers a possibility for further increasing the profitability of slaughterhouses. Flottweg decanters with free overflow are used for dewatering coagulated animal blood. Thanks to the adapted scroll geometry, high cake dryness in the solids discharge can be achieved with excellent separation performance.

CREATING CREATING VALUE VALUE FROM FROM FLOTATION FLOTATION SLUDGE SLUDGE Flotation is a separation technology that separates particles from the water during wastewater treatment and separates them at the surface by means of gas bubbles — as flotation sludge. Meat/poultry processing companies also use flotation to purify their process water. However, the resulting flotation froth is both difficult-to-dispose residual waste and a potentially valuable mixture of fat and proteins. It is therefore important to combine disposal and value creation. The post-treatment of flotation sludge with a Flottweg...

SPECIAL SPECIAL FEATURES FEATURES OF OF THE THE FLOTTWEG FLOTTWEG DECANTERS DECANTERS AND AND TRICANTERS® TRICANTERS® Flottweg decanter Flottweg decanters are e.g. installed upstream of thermal processes in order to separate liquids from solids (2-phase process). Due to the special design of the Flottweg decanter, the separated solids reach high dry substance levels. This has several positive effects on the overall energy balance of the plant, as centrifugal (mechanical) separation requires less energy for water removal than thermal separation. The steam requirement in downstream drying processes...

Flottweg Simp Drive® Flottweg impeller (standard for Tricanter®, optional for decanter) The Flottweg Simp Drive® regulates the differential speed based on the scroll torque. As a result, the Flottweg decanter/Tricanter® automatically adapts to varying load conditions and dewaters the supplied product to the respective maximum dry solids content. ∙ Lowest energy requirements due to high efficiency ∙ Pure motorized operation, therefore no oversizing of the drive motors The adjustable impeller allows infinite adjustment of the pond depth during operation and thus fast, precise adaptation to changing...
