Types of fish feed extrusion machinery

Fish have become one of the ideal foods for the public, and the fish farming industry is increasingly diversifying. It is reported that the main machines used for making fish feed on the market currently include:

1. Pellet feed production line

To prevent pellet feed from immediately dispersing in water, a steam conditioning configuration is generally added to the feed machine to enhance the binding properties of the feed.

2. Feed extrusion machinery

To develop new feed sources, feathers, poultry, and livestock manure are extruded to turn them into feed. Soybean meal, rapeseed cake, cottonseed cake, etc., are also extruded.

3. Pellet feed coating equipment

To extend the stability time of pellet feed in water, oil film spraying equipment is generally added at the outlet of the pellet feed machine. However, due to the high moisture content of the pellets at that time, with the finished product moisture exceeding 15%, drying is carried out first before spraying.

4. Fresh soft pellet feed processing complete set of equipment

Fresh feed is mashed into a paste, mixed with other powdered feed, and processed into fresh soft pellet feed to preserve the active substances of live bait.

5. One-step pellet feed processing complete set of equipment

This equipment does not require water vapor or feed during processing, operating with dry input and dry output. When the raw material moisture content is less than 13%, the product moisture content is less than 11%, eliminating the need for drying.

6. Sink-first-then-float pellet feed processing complete set of equipment

Its product is a relatively recommended pellet feed for prawns, which does not disintegrate when submerged in water and can float to the surface after a few hours, reducing water pollution and saving feed.

7. Normal temperature and pressure floating pellet feed processing equipment

This equipment does not require heating facilities; pellet feed processed at normal temperature and pressure can also "float immediately" and remain floating for several hours without dispersing.

8. Ultrafine grinding processing complete equipment

To make feed easier to digest and absorb, sieve-free ultrafine grinding technology is generally used, which can be fed to larger fry or used as raw material for pellet feed.

9. Microencapsulated feed processing complete equipment

It allows micro-pellets to be naturally coated on the outside, then spray-dried into shape, with feed pellet diameters ranging from 3 microns to 10 microns, reaching over 700,000 pellets per milligram.

Fish and shrimp feed processing equipment has gradually separated from livestock and poultry feed processing machinery abroad, forming its own system. Only when aquaculture is fully mechanized and modernized can its output and quality be significantly improved. The synchronous development of aquaculture and modern mechanized equipment is an inseparable systematic project. At present, the characteristics of feed extrusion machinery among the above equipment make it increasingly popular in the market. The feed extrusion machinery produced by Jinan Datong Company has stable output and uniform particle texture. Customers are welcome to inquire and place orders at any time.
