Flow Chart




Floating Fish Feed Processing Line focuses on the production of feeds for animals with a high emotional value but low economic usefulness, apart from the aspect of breeding. Nonetheless, balancing the components and gentle processing are at the center of the related quality considerations. Extrusion is therefore increasingly proving to be the right tool for modern Pet food. A complete feed, fed as a diet over a prolonged period of time, must ensure the vitality of the animal and prevent deficiencies. This is quite a challenge to the feed manufacturer in terms of the selection and composition of the raw materials, their optimal processing, and effective quality assurance. A large number of pet food products are made by extrusion.
1) Dog and cat foods, directly extruded and dried, dry or semi-moist. These constitute the biggest market segment.
2)Feed for fish, high-grade complete feeds capable of maintaining the health even of exotic species in aquariums over prolonged periods of time, sinking or floating feed.
Darin focuses on reliability, safety, and long-term performance. Every key component is carefully selected to ensure stable operation, easy maintenance, and consistent product quality.
Motors are from Siemens, ensuring strong driving force, stable operation, and extended machine lifespan, even under long-time continuous production.

Electric parts are from ABB or Schneider, internationally recognized brands.
Easy to find replacements in the local market, reducing downtime and maintenance costs.


PLC and touch screen are from Siemens, providing intuitive operation and reducing labor requirements.
Operators can control the entire line easily with minimal training.

The PLC and touch screen control the whole processing line, not just one or two individual machines.
This ensures better coordination, higher efficiency, and smoother production flow.

When a fault occurs, relevant information is displayed directly on the touch screen, allowing operators to identify and solve problems quickly, without checking machines one by one.

The control cabinet uses 24V safe voltage (not 220V), which effectively protects operators, even in case of electrical leakage.

Three kinds of protectors ensure maximum safety for both machine and operator:
Over-current protection
Over-voltage protection
Over-heat protection
This multi-layer protection guarantees safe and reliable long-term operation.
All cover bodies, mesh belts, and parts in contact with raw materials or final products are made of Stainless Steel 304, meeting food-grade standards and ensuring hygiene, corrosion resistance, and easy cleaning.

With world-famous components, advanced control systems, and strict safety design, Darin machines are trusted by customers worldwide for stable performance, easy maintenance, and long-term value.
