As a forage grass, Napier grass has high nutritional value and good palatability. It is a high-quality green fodder for livestock and poultry such as cattle, sheep, pigs, rabbits, geese, fish, and herbivorous fish. It can be silaged or dried and pelleted into feed.The process of drying Napier grass into pellet feed is a complex process involving multiple steps, mainly including raw material preparation, drying, crushing, mixing, pelleting, cooling and packaging.
Napier Grass Pellet Pellet Production Plant Process:
1. Drying: Put the forage grass into the dryer and set the appropriate drying temperature and time according to the type of forage grass and the initial moisture content. The state of the forage grass needs to be checked regularly during the drying process to ensure that the drying is uniform and not excessive.
2. Crushing:Crushing treatment: The dried forage grass is crushed into fine fragments or grass powder by a crusher to facilitate the subsequent pelleting process. The degree of crushing should be determined according to the digestive characteristics of the animal and the requirements of the pellet feed equipment.
3. Mixing:Ingredient mixing: According to the nutritional needs of animals, the crushed forage is evenly mixed with other feed ingredients (such as grains, protein concentrates, minerals, vitamins, etc.) to prepare a nutritionally balanced complete pellet feed. The mixing process should ensure that the various ingredients are fully mixed to avoid stratification.
4. Granulation:Granulation process: Use a special pellet feed pelletizer to compress and mold the mixed feed raw materials. During the pelletizing process, the raw materials are stirred and extruded under high temperature and pressure, and then extruded from the sieve holes of the machine to form pellets.Adjusting particle size and hardness: By adjusting the parameters of the pelletizer (such as pressure, die hole size, etc.), the diameter and hardness of the pellets can be controlled to adapt to the feeding habits and digestion capacity of different animals.
5. Cooling:Cooling treatment: The pellets just out of the pelletizer have a high temperature (up to about 80°C) and need to be quickly cooled to room temperature through the cooling system. The purpose of cooling is to prevent the redistribution of moisture inside the pellets and cause mildew, while reducing the moisture content to a level suitable for storage.
6. Packaging:Sealed packaging: After cooling, pellet feed should be sealed and packaged in time to prevent moisture absorption, oxidation and insect pests, ensuring the stability of feed quality during storage and transportation.
