Introduction
Fish feed plays a vital role in the successful aquaculture industry. To produce high-quality fish feed, efficient machinery plays a critical part in the process. Two types of fish feed machines are available: floating fish feed making machinery and sinking fish feed machine. This article will discuss the differences between the two technologies.
Technology
The production process of floating fish feed making machinery and sinking fish feed machines are vastly different. Floating fish feed making machinery works by extruding and puffing the feed into a floating form. The expansion occurs due to the inclusion of low-density ingredients like corn, wheat, and other grains. The puffed feed floats for a prolonged period, allowing the fish to have ample time to feed. Sinking fish feed machines, on the other hand, are similar to the conventional pellet mills. Sinking fish feed is produced by pressing the ingredients into compact pellets to sink to the fish bottom, where the fish feed from.
Production Capacity
The production capacity for both floating fish feed making machinery and sinking fish feed machines is dependent on the type of machine used. The capacity of the machinery should be chosen based on the size of the fish farm or production unit. Typically, the production capacity of sinking fish feed machines ranges between 60-600kg/hour, while that of floating fish feed making machinery ranges between 50-300kg/hour.
Feed Quality
Floating fish feed making machinery and sinking fish feed machines differ significantly in feed quality. The nutritional and physical properties of the fish feed determine the acceptance and growth of fish. Floating fish feed making machinery improves feed quality with high buoyancy, stability, and palatability. As such, it allows for easier handling and feeding, making fish farming more efficient. On the other hand, sinking fish feed machines produce pelletized feeds that sank to the bottom of the water. The fish feed is prone to spoilage since it becomes exposed to water, leading to loss of nutrients and potency.
Operating Cost
Operating costs for floating fish feed making machinery and sinking fish feed machines vary, mainly due to their processing technologies. Floating fish feed making machinery requires that raw materials be pre-processed, making the process more time-consuming and expensive. In contrast, sinking fish feed machines require less processing time, increasing their efficiency, reducing the production cost, and maximizing the profit margin.
Environmental Impact
The environmental impact of fish feed production is a crucial factor that farmers need to consider. In this regard, floating fish feed making machinery is more eco-friendly compared to sinking fish feed machines. Floating fish feed making machinery produces feeds that are more user-friendly to fish, reducing waste and environmental pollution. They reduce fish metabolic waste discharge, keeping the water in the fish pond healthy and clean. The sinking fish feed machines, however, produce feed with a higher risk of pollution, tainting the fish pond water and the surrounding environment.
Conclusion
To summarize, floating fish feed making machinery and sinking fish feed machines are two types of fish feed processing machines available in the market. They differ in their production process, production capacity, feed quality, operating cost, and environmental impact. However, a well-informed buyer can choose the right machine based on their specific fish farming requirements, environmental and financial constraints, and end goals.
