company news about What Kind of Feed Uses a Dry fish feed production equipment?

High-fiber aquatic feed: suitable for the needs of herbivorous fish. Grass carp, bream, and other herbivorous fish require feeds containing large amounts of coarse fiber (such as bran, peanut meal, and straw powder). The production of this type of high-fiber feed must utilize a dry fish feed pellet extruder.

High-fiber raw materials have low moisture content (typically 8%-12%) and a rigid fiber structure. When water is added to a wet extruder, the fibers easily absorb water and swell, leading to feed blockage. However, a dry-type fish feed pellet processing machine requires no additional water. The high-speed rotation of the screw (350-400 rpm) generates significant frictional heat, which quickly softens the fiber structure. Simultaneously, high-pressure extrusion fully melts and expands the raw materials, forming compact pellets. For example, when producing high-fiber feed for grass carp, adding 30% bran and adjusting the screw speed to 380 rpm in a dry extruder fully softens the fibers, producing pellets with moderate hardness. Grass carp achieve a digestibility and absorption rate of over 75%. If a wet extruder were used, problems such as feed blockage and loose, easily collapsing pellets would occur. Low-moisture livestock and poultry compound feed: Ensuring storage stability. Some livestock and poultry compound feeds (such as beef cattle fattening feed and sheep feed) require low moisture content (≤12%) to improve storage stability and prevent mold growth. Dry-type floating fish feed pellet making machines are suitable for producing these feeds.

Dry extruders produce feed pellets with the required moisture content directly, eliminating the need for additional drying processes and effectively ensuring storage stability. For example, when producing beef cattle fattening feed, the raw materials are corn, soybean meal, cottonseed meal, etc., with a moisture content controlled at 10%-12%. Using a dry extruder, the produced pellets have a moisture content of around 11%, a shelf life of over 6 months, and are less prone to mold. If a wet extruder is used, the produced pellets have a moisture content of 18%-22%, requiring additional drying to below 12%, which not only increases energy costs but also leads to the loss of some nutrients.

Rough fiber pet food: Suitable for the chewing resistance needs of large dogs. Large breed dog food (such as Tibetan Mastiffs and German Shepherds) typically contains 15%-25% crude fiber (such as beet pulp and cellulose). This type of food requires a dry-type fish feed making machine. Crude fiber enhances the food's chewability and promotes intestinal motility in large dogs. Dry extrusion produces pellets with a compact structure and high chewability, meeting the chewing needs of large dogs. For example, when producing adult large breed dog food, adding 20% ​​beet pulp and using a dry extruder results in pellets with a hardness of 15-20N. Large dogs require more chewing time, effectively cleaning their teeth and preventing tartar buildup. If a wet extruder is used, the resulting pellets have a loose structure and poor chewability, failing to meet the needs of large dogs.
