SPECIAL STORY 56 FEED & ADDITIVE MAGAZINE July 2022 MOISTURE CHANGES AND CONTROL MEASURES DURING THE PELLET PROCESSING “Today, when the price of raw material is soaring and the market competition is very fierce, feed enterprises are required to comprehensively control various factors, according to different situations in the whole process of production, so that the final moisture content of the product can reach the expected goal of the producer, and ensure the quality of pellet feed.” The moisture content of the final pelleted feed is closely related to the moisture change during the feed production. The total loss of moisture in the feed production process can reach up to 1.5%. Moisture loss not only seriously affects the economic benefits, but also affects the quality and palatability of the pellets. Understanding this moisture changes in the production process and comprehensively regulating it, can help feed enterprises achieve the purpose of controlling the moisture content of the finished pellets. It will be analyzed the factors affecting in the content of moisture during the process and how ADIVETER 4.0, is a very innovative and unique technology in the market, developed to prevent losses during entire process due to moisture variation of raw materials and controlling cooler operating process to increase feed quality. Moisture changes at the grinding process During the grinding process of the raw materials, heat is generated by the impact and friction between the high-speed rotating hammer and the raw material. The temperature inside the crushing chamber is higher than the outer temperature generally around 45 ºC to 50 ºC. The moisture loss in that process is generally between 0.5% and 1.5%. The loss degree is related to the particle size1, type of hammer mill2 and temperature3. The moisture lost in this process, will need to be added later in the process to ensure good moisture and quality pellets. Moisture changes and control measures in the mixing process with Adiveter 4.0 (Pellet Plus Online) After the grinding process, the raw materials are mixed to get and homogenous meal in the mixer. When the moisture content of the mixed powder is much lower than 12.5%, it is recommended to add atomized free water during the mixing. But there are many problems in this aspect: 1. The retention performance is poor. Ignasi Vives Product manager - Feed Process Optimization Adiveter
