Pig feed should be processed before being fed to the pigs in order to make it simple to digest and remove harmful and poisonous components. The principal methods of processing include grinding, pelletizing using an animal feed pellet maker, extruding, roasting, cooking, fermenting, mashing, and ensiling, among others. How can I make my own poultry feed?
The steaming, heating, and pressure treatments used in the pelletizing process can cause feed ingredients' starch to become aged and gelatinized. Research demonstrates that the pelletizing process can increase the palatability and digestibility of pig feed, deter pigs from picking up feed, and thus reduce waste and increase feed intake rate. Pelletized pig food can increase feed efficiency by 5% to 15%.
Pig feed pellets are typically sent to a feed pellet cooling machine as soon as they are removed from the feed pellet machine. Pig feed pellets have a moisture content after cooling that is less than 14%, making them resistant to mildew.
Because they are compact and dense after pelletizing, pig feed pellets are simple to transport and store. Unlike powdered pig feed, the uniformity of the ingredients in pig feed pellets cannot be compromised, preserving the nutrient content and palatability.
Making High-Quality Pig Feed
Since pig feed produced by a feed pellet mill has so many benefits, it is crucial to produce high-quality pig feed pellets. Here are some pointers for using a ring die pig feed pellet machine to produce high-quality pig pellets.
Ingredient cohesion in feed
Add some starch to your feed ingredients if you want to create pig feed pellets that look good. The most significant element influencing the cohesiveness of pig feed pellets is starch. The steam and heat used in the pelletizing process can cause starch to gelatinize and produce cohesiveness, which can aid in the binding of various feed ingredients. The better the cohesiveness, the more starch there is. Different sources of starch have different levels of cohesiveness. Wheat and barley have stronger starches that are more cohesive than corn. Since soybean meal contains little fat, it is cohesive.
If milk powder, whey powder, sugar, or glucose are present in the feed ingredients, the feed material will also have good cohesiveness when making piglet feed pellets using a feed pellet machine.
Temperature, steam pressure, and moisture content
The necessary conditions and key elements for starch gelatinization and cohesiveness are moisture content and temperature. The hardness is increased if the moisture content of feed ingredients is higher than 8 to 10 percent. The supply volume of steam is typically 3-6% of the supply volume of feed material. The overall moisture content can be between 16 and 17 percent in this way.
When the feed pellet machine's pelletizing temperature is too low, starch gelatinization is insufficient, which reduces the pelletizing effect; when the temperature is too high, nutrients, especially vitamins, will seriously degrade. The required temperature cannot be higher than 88 °C. Depending on the pellet formation status and the moisture content of the feed pellets after cooling, the temperature can vary from 82 °C to 88 °C. Temperature can be raised if pellet formation is subpar and moisture content is high.
The right steam pressure will produce a good pelleting effect; it is directly related to the moisture content and pelleting temperature. Steam pressure is typically maintained between 394 KPa and 490 KPa. High steam pressure results in large steam supply volumes and high steam temperatures.
The finished feed pellets are known as raw feed pellets if cold pressing, or the direct pressing of feed materials into feed pellet mill die, is used. The feed pellet machine, also known as a flat die feed pellet mill, is used to create raw feed pellets for animals. It can be powered by either an electric motor or a diesel engine. However, because the raw feed pellets produced by flat die pig feed pellet mill do not undergo the aging process, the pellet formation status is worse; the amount of power in finished pig feed is higher; the palatability and feed use efficiency are lower than those of feed pellets produced by ring die pig feed pellet making equipment.
