Abstract
Total Mixed Ration (TMR), a system used in combining materials into feed for animals in the right proportion is a complex process especially when by-products are utilized. This involves several steps and unit machines. The current study focused on modeling a fermentation and storage system utilizing by-products for TMR feed production using the Arena V15 simulation program. Process time, operation rate, and bottleneck phenomenon were analyzed. The optimal capacities of unit machines were estimated using Opt-quest, an extension of the simulation program. Results showed the optimal operation rate of the mixer was 99% at 8.5 ton/h capacity and that of the steam sterilizer was 93% at 17.6 ton/h capacity. Moisture regulator was 89% at 7.0 ton/h capacity, while those of the vehicle loader and packaging device were 83.3 and 100% at 12.8 and 2.67 ton/h respectively. A field trial to verify the simulated results was conducted at Hwaseong Dairy Corporation. It shows mean square error and standard deviation between the simulated results and the field trial were within 5% range indicating a significant relationship. This work developed a livestock feed fermentation and storage model for cattle at an optimal performance.
总混合日粮(TMR)是一种以适当比例将原料混合成动物饲料的系统,是一个复杂的过程,特别是在利用副产品的情况下。这涉及到几个步骤和单元机器。目前的研究重点是利用Arena V15模拟程序对利用副产品生产TMR饲料的发酵和储存系统进行建模。分析了工艺时间、运行率和瓶颈现象。利用仿真程序的扩展Opt-quest估计了单元机的最优容量。结果表明,混合器在8.5 t /h时的最佳运转率为99%,蒸汽灭菌器在17.6 t /h时的最佳运转率为93%。湿度调节器在7.0 t /h时为89%,装载机和包装装置在12.8和2.67 t /h时分别为83.3%和100%。为了验证模拟结果,在华城乳业公司进行了现场试验。结果表明,模拟结果与现场试验的均方误差和标准差均在5%的范围内,关系显著。本工作为牛的最佳生产性能建立了一种家畜饲料发酵贮藏模型。
