company news about What are the functions of an aquatic feed pellet production line?

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 a built-in screen to filter out stones and weeds, preventing damage to subsequent equipment and preventing fish and shrimp from choking.

2. Precise Mixing Function: Ensures uniform nutrition and prevents picky eating: Manual mixing of raw materials like fishmeal, calcium powder, and vitamins can easily result in uneven mixing. Some fish and shrimp will only eat the meat meal, while others will only eat the cornmeal. The production line's mixer automatically mixes according to pre-set ratios (e.g., 20% fishmeal + 50% cornmeal + 30% soybean meal), achieving a 10-fold more uniform mixing than manual mixing. Each pellet has the same nutritional value, resulting in uniform growth of the fish and shrimp.

3. Extrusion Molding Function: Produces foam-resistant sinking/floating feed: This is the core function. Based on the habits of aquatic animals, it can produce sinking feed (for shrimp and crab, sinks in 10 seconds) and floating feed (for silver carp and bass, floats for 4-6 hours). The high-temperature, high-pressure extrusion process forms a protective film on the feed surface, preventing it from disintegrating in water and polluting the water. Fish and shrimp can consume it without waste.

4. Drying and Cooling Function: Longer Feed Storage: Freshly extruded feed is wet and will mold after a few days. The production line's dryer reduces the feed moisture content to below 12%, and after cooling, the bagged feed can be stored for 1-3 months, even in rainy weather, eliminating the need for daily feed preparation.

5. Automatic Packaging Function: Labor Saving and High Efficiency: The dried feed goes directly into the packaging machine, where it is automatically bagged, weighed, and sealed. Bags can be adjusted to 50 or 100 catties, eliminating the need for manual loading. Only 2-3 people are needed to supervise the production line, making it 5 times faster than manual packaging.
