The primary selection principle is "product demand-oriented," determining the equipment type based on feed type and core performance indicators. For producing floating fish feed, high-fiber aquatic feed, and complete pet food, a wet extruder is essential, as its precise control of moisture and ...

In terms of initial investment costs, wet extruders are significantly more expensive than dry extruders. A dry extruder with an hourly capacity of 1 ton costs approximately 150,000-250,000 yuan, primarily due to its simple structure and lack of need for steam and water addition systems. In contrast, ...

The most obvious difference lies in physical properties, primarily reflected in three indicators: hardness, expansion rate, and water resistance. Regarding hardness, feed produced by dry extruders, due to its lower moisture content and denser structure, generally has a hardness 50%-80% higher than ...

The core application scenario for dry fish feed production equipment is the production of "low-moisture, high-energy" feeds, especially suitable for pet snacks, sinking aquatic feeds, and specialty low-moisture feeds. In the pet food industry, when producing treats such as jerky and chew sticks, the ...

The dry-type small fish feed pellet making machine operates on the core principle of "mechanical frictional heat generation." It requires no additional water or steam, relying entirely on the high-intensity extrusion and shearing action between the screw and barrel to generate heat, raising the raw ...

1. Low-cost raw material processing function: Turning waste into treasure and saving big money: To control the cost of freshwater fish feed, the production line can process locally sourced, inexpensive raw materials, such as dried sweet potato vines and peanut shells. After being ground into powder, ...

1. Ultra-fine grinding function: Raw materials finer than millet: Birds have narrow esophagi, and coarse materials are difficult to swallow. The production line's grinder is a "double-stage grinder," first grinding corn and rapeseed into coarse powder, then grinding them into an ultra-fine powder ...

1. Fresh Meat Processing Function: Minced and Sterilized: Fresh chicken breast and beef require no pre-treatment; simply pour them into the meat grinder, where they are automatically minced into a fine paste. Then, a low-temperature sterilizer (80-100℃) kills Salmonella, preserving nutrients while ...

1. Raw Material Pre-treatment Function: Transforms coarse feed into fine feed and removes impurities: Freshly purchased corn and soybean meal are whole grains, unsuitable for fish and shrimp. The production line's grinder first grinds them into a fine powder, even finer than flour. It also includes ...
