कंपनी की खबर How to optimize the production capacity of fish and shrimp feed production lines

Many fish and shrimp feed mills have encountered this problem: their production line, which is supposed to produce 10 tons per day, only actually produces 8 tons. This is either due to clogged feed mills causing delays, or unstable extruder temperatures leading to substandard pellets, necessitating shutdowns for adjustments. However, by finding the right optimization methods, the pet floating meal production line can operate at full capacity, increasing production output. Below, we'll discuss specific optimization techniques.

This is reflected in three aspects

First, optimize the "raw material pretreatment process" to reduce clogging and rework. Fish and shrimp feed ingredients (such as fishmeal and soybean meal) are prone to absorbing moisture and clumping, causing blockages in the grinder and frequent shutdowns for cleaning. Optimization methods for floating fish food production lines are simple: one, install a "drying device" in the raw material silo to control the moisture content of the raw materials at 12%-14% to prevent clumping; two, install a "vibrating screen" at the grinder inlet to pre-screen out large lumps and prevent blockages. For example, one feed mill previously experienced 3-4 instances of grinder blockage per day, each requiring 20 minutes of cleaning; after optimization, blockage only occurs once a day, resulting in an additional ton of feed production per day. Additionally, high-protein ingredients such as fishmeal tend to stick to the mixer walls. Applying an "anti-stick coating" to the inner wall of the mixer can ensure more uniform mixing, reducing rework due to uneven mixing and further improving efficiency.

Second, upgrade "core equipment parameters" to improve single-machine efficiency. The extruder is the core of the floating feed production line; unstable temperature and rotation speed can affect production speed and pellet quality. Optimization methods include: First, equipping the extruder with an "intelligent temperature control system" to precisely control the temperature between 115-125℃ (the optimal extrusion temperature for fish and shrimp feed), preventing substandard pellets due to excessively high or low temperatures. Second, replacing ordinary motors with "variable frequency motors," adjusting the speed according to the moisture content of the raw materials; for example, lowering the speed when the raw materials are wet (200 rpm) and increasing the speed when the raw materials are dry (300 rpm), ensuring the extruder always operates at its optimal state. After upgrading, a feed mill saw its extruder's production speed increase from 800 kg/hour to 1000 kg/hour, directly increasing daily output by 2 tons. Simultaneously, replacing the ordinary ring die in the pellet mill with a "wear-resistant ring die" extended its service life from one month to three months, reducing downtime for die changes and further improving production capacity.

Finally, optimizing the "production process connection" to avoid disconnections between stages. If the processes in an animal feed extruder line (grinding → mixing → extrusion → cooling) are not well coordinated, situations can arise where "the previous stage runs out of material while the next stage is waiting for it." Optimization methods include: 1) adding "buffer silos" between stages, such as between the mixer and the extruder, to store the mixed raw materials beforehand, eliminating the need for the extruder to wait for material; 2) establishing "standardized operating procedures," clearly defining the operation time and connection points for each stage, such as the grinding stage feeding 1 ton of material to the mixer per hour, and the mixer feeding 1 ton of material to the extruder per hour, ensuring consistent pace across all stages. After optimizing its process, a feed mill reduced its production line downtime from 2 hours to 30 minutes per day, increasing daily output by 15%.
