Many pet cat food manufacturers have reported that their production lines frequently shut down due to mold changes and formula switching, and that a significant number of the produced pellets are substandard, requiring rework and screening, resulting in actual output being much lower than designed output. However, with targeted optimization, production capacity can be increased while maintaining cat food quality. Below are some specific methods.

This is reflected in three aspects

First, optimize the "mold changeover process" to reduce downtime. Cat food requires different sized pellets (2mm for kittens, 3mm for adult cats). A complex mold changeover process can waste a lot of time. Optimization methods include: 1) replacing traditional molds with "quick-release molds," which require only unscrewing four fixing screws, reducing changeover time from 1 hour to 15 minutes; 2) preparing spare molds in advance, such as directly switching to adult cat food molds after producing kitten food, eliminating the need to find and clean molds on the spot. After optimization, one feed mill reduced the number of mold changes per day from 3 to 2, saving 45 minutes each time and increasing daily cat food production by 500 kg. Additionally, applying "anti-stick oil" to the mold surface reduces raw material adhesion, further saving cleaning time.

Second, upgrade the "formula mixing system" to improve switching efficiency. Cat food formulas are diverse (e.g., chicken flavor, fish flavor, urinary tract protection formula). Switching formulas requires cleaning the mixer to prevent flavor mixing or nutritional imbalances. Optimization methods include: First, equipping the mixer with a "rapid cleaning device," such as installing high-pressure spray nozzles on the inner wall of the mixer. When switching formulas, a 5-minute rinse with water is sufficient to clean it, saving 25 minutes compared to manual cleaning. Second, using "multiple mixers in rotation," for example, one mixer can produce chicken-flavored formula while another produces fish-flavored formula, eliminating the need to wait for one to finish cleaning before starting the next, thus achieving continuous production. After upgrading, a feed mill reduced formula switching time from 30 minutes to 10 minutes, allowing for two more formulas to be switched daily, increasing output by 20%.

Third, optimizing the "pellet screening process" to reduce rework. Cat food requires high pellet uniformity; substandard pellets (broken or oversized pellets) need to be screened out and reprocessed, which wastes time. Optimization methods include: First, installing a double-layer vibrating screen after the cooler. The upper screen removes oversized particles, while the lower screen removes broken material, increasing screening efficiency by 50% compared to a traditional single-layer screen. Second, installing a particle detector at the pellet mill outlet to monitor particle size and hardness in real time. If particles fail to meet specifications, the pellet mill parameters are adjusted promptly to prevent the production of large quantities of substandard particles. After optimization, a feed mill reduced its substandard particle rate from 10% to 3%, saving 200 kg of rework feed daily and naturally increasing production capacity.
