Once cooked, the material is introduced through the feed inlet. Owing to the design of the twin-screw press, where the screw pitch gradually diminishes towards the discharge end while the diameter increases, the material within the screw channels is progressively compacted. Throughout this process, the interplay between the twin screws not only prevents the material from rotating with the shaft but also intensifies the mixing and shearing effects on the material, facilitating dewatering and defatting. As the material is continually compressed, the liquid continuously seeps through the mesh screen of the stainless steel filter, accumulates in a juice pan, and then flows into a stainless steel protein water tank via an outlet; the pressed cake, on the other hand, drops from the discharge end and is conveyed to a drying machine by a screw conveyor.
Features:
1. The feed hopper is equipped with an automatic control system that regulates the material level, ensuring that the cooking equipment's feed opening is consistently filled, which guarantees an even and continuous cooking process.
2. An internal shaft heating system and a shell jacket indirect heating method are employed to thoroughly cook the raw fish material. This approach avoids the introduction of excess condensate, which can occur with direct steam injection heating, thereby preventing the loss of protein in the fish meal.
3. A variable frequency drive motor is utilized for power, enabling adjustments to the cooking machine's speed to accommodate different seasonal conditions, fish species, and variations in fish size, meeting the requirements of various production processes.
4. A condensate recovery system is implemented to recycle steam condensate back into the boiler, enhancing boiler efficiency and reducing energy consumption.
5. The main shaft is fitted with an automatic pressure-adjustable sealing device at both ends to prevent any leakage from the cooking machine, maintaining hygiene within the facility.
6. A steel base structure is included, eliminating the need for a concrete foundation.
