1. Our floating fish feed making machine's extruders are twin-screw extruders, there are one couple of screws inside the barrel. The screws are combined screws, which is economical and practical for users (if screws are abrasive, the user don't need to change whole screws, only change the end part of the screws). The raw material of screws is 38CrMoAl (standard: GB/T 3077-1999), which is processed for nitriding treatment. This material's hardness and strength performance is excellent, which can bear high temperature and high pressure.
2. Our twin-screw extruder has forced lubrication and cooling system. This system can protect gears, axles and bearings, which can increase of service life. We can add cooling system (outside barrels) according to users' request.
3. Our twin-screw extruder has self-clean function. When maintenance, the users don't need to extract the screws. The screws can be cleaned by adding waste material.
4. Except screws, barrels, dies or blades, the other parts touching food is stainless steel or food grade plastic. It is sanitary and safety. (Screws, barrels, dies and blades have to bear high temperature and high pressure, they can't be stainless steel, or they will be broken.)
5. Our extruders, dryers and cutting machines (if any) are equipped with inverters. Our standard inverters' brand is Delta (Taiwan), we can supply the other inverters as per users' requirement, such as LS (Korea), ABB (Switzerland), Siemens (Germany).
6. Our floating fish feed making machine automation degree is high. For small capacity lines, they need 2 workers to operate; for big capacity line, they need 3-4 workers to operate. It can save owner's labor cost. Our expanded fish feed processing lines' field area is small. The machineries can be placed in line, in L shape, even in U shape. It can save users' workshop investment.
