How Raw Materials Determine The Type Of Fish Feed Pellet Extruder
Leave a message
The core processing challenge for high-protein raw materials lies in their high heat sensitivity and large viscosity fluctuations. Animal proteins such as fishmeal and meat and bone meal are prone to excessive denaturation at temperatures exceeding 120℃, leading to the destruction of their amino acid structure and loss of nutritional value. Plant proteins such as soybean meal tend to become sticky during extrusion, clogging the mold. Therefore, a suitable pellet mill must meet the core requirements of "low-temperature extrusion and uniform pressure distribution." Twin-screw fish food making machines, with their co-rotating twin-screw structure, ensure thorough mixing and shearing of raw materials within the barrel. The extrusion temperature can be controlled at 90-110℃, while the pressure distribution is uniform, preventing localized overheating, making it the optimal solution for high-protein raw materials. Its special barrier-type screw design also prevents sticky materials from adhering to the walls, reducing cleaning frequency.
For small- to medium-scale customers processing single plant protein raw materials such as soybean meal and cottonseed meal, single-screw fish feed pellet making machines offer a cost-effective option, but require a forced feeding device and cooling system. Forced feeding devices solve the problem of poor flowability of plant proteins, ensuring uniform feeding; cooling systems can quickly reduce pellet temperature from 100℃ to room temperature, preventing continuous protein denaturation during subsequent storage. A small feed mill in Hebei province, when processing soybean meal feed, used a single-screw pellet mill with an air-cooling system, increasing the pellet protein retention rate to 92%, meeting the needs of local farmers.
When selecting a pellet mill, the fat content of the raw materials must also be considered. High-fat raw materials such as fishmeal (fat content > 15%) can easily cause slippage in the pellet mill die. Therefore, special dies with a surface roughness of Ra1.6 should be selected, along with a quantitative feeding system for a twin-screw floating fish feed extruder machine, to ensure stable pellet formation. At the same time, the material of the equipment is also crucial. Parts in contact with the raw materials must be made of 304 stainless steel to prevent corrosion from acidic substances in high-protein raw materials, extending the equipment's service life.
