Energy efficient grinding of fish and shrimp feed recipes
Tietjen’s grinding and pulverizing solutions stand for efficiency, high fineness and the tightest grist spectrum for aqua & shrimp feed processing.
Energy efficient solutions for the production of aquatic feed
A large grist spectrum and irregular fineness often result in higher energy consumption and longer retention time in the mill. This might cause
- high production cost
- a suboptimal grist spectrum (increased proportion of fines),
- heat exposure for sensitive nutritional elements in the recipe and
- an increased likelihood for blockings and dust explosions.
From the economic side, a higher fineness normally goes with lower throughput and higher energy cost of the line. Tietjen offers valuable alternatives here, such as pre-shredding and grinding systems which reduce the energy consumption.

Influencing the quality of aqua and shrimp feed pellets
The quality of aqua or shrimp feed increases with the fineness of the grinding and pulverizing process.
- Reduced incidence of die plugging in extruder, due to uniformity and cleanness of the ground material
- Ease of cooking in the extruder and pelletizing efficiencies
- Better binding properties and reduced waste due to finer structure
- Improved liquid and steam addition due to small and uniform cell structure
- Less wear in the extruder barrel
- Ease of drying process
