Mozzarella干酪拉伸机的设计

摘要

The design of Mozzaralla cheese stretcher is desribed in this paper, which includes theory analysis,mechanical design and preparation trial. The stretcher is controllable to heat and stretch the cheese curd. An die plate with even-distributed small holes is installed at the outlet of the stretcher. 20 mm-30 mm diametered cheese is extuded directly to the receiver. The smaller-sized cheese would reduce the chilling time. Through the preparation trial, the stretched sample is up to the USDA standard for Mozzaralla cheese..%描述一种用于生产Mozzarella干酪的单螺杆拉伸机的设计,包括理论分析、机械设计以及试验论证.该拉伸机可以实现对凝乳颗粒的可控加热与拉伸,同时,为了直接获得直径20 mm～30mm的干酪块,在拉伸机出口处安装了小孔均匀分布的挤出板,使小尺寸的干酪块冷却时间缩短.该机试制的样品符合美国农业部关于Mozzarella干酪产品的标准.
