描述：	世界上最大的乳品单体公司 ——光明乳业华东有限公司 / LWShanghai 校外探索课堂/ 经济学@LWS X 光明乳业【Date：2021.06】 LWShanghai LWShanghai LWS把经济学课堂搬入了光明乳业这是一次跨界的合作，世界上最大的乳品单体公司与福布斯中国40强的国际学校。把选修经济学孩子们的课堂搬到了光明乳业华东有限公司的车间里，了解企业的产业链架构。 (向左滑动查看更多照片) 很幸运 LWS美高学校经济学的孩子们成为疫情后第一批来参观的学生在两个小时的参观中，我们了解到了不同的乳制品是如何从牛奶一步步通过机器加工和流水线变成我们日常见到的乳制品。更重要的是，通过参观流水线，同学们把课堂上的经济知识运用在生活中，例如固定成本和可变成本。参观实际的流水线让同学们更好得理解课堂中的知识，十分有意义。 I was lucky to be one of the first students to visit after the outbreak. During the two-hour visit, we learned how different dairy products are transformed from milk through machines and assembly lines into the dairy products we see every day. More importantly, by visiting the assembly line, students applied the economic knowledge learned in class to life, such as fixed costs and variable costs. Visiting the actual assembly line made students better understand the knowledge in class, which was very meaningful. LWShanghai 光明乳业与经济学的关联光明牛奶厂在经济中属于垄断竞争。垄断市场是指市场中具有众多的生产者和消费者，而且消费者具有明显的偏好，商品与服务“非同质”；市场的进入与退出完全自由的；各生产者提供的众多商品是有差别，但并没有本质区别。光明牛奶厂制造乳制品，除了光明以外还有其它品牌的牛奶,例如伊利，明治。所以产品有替代性。 Bright Milk Factory is a monopolistic competition in the economy. Monopoly market means that there are many producers and consumers in the market, and the consumers have obvious preferences, and the goods and services are "non-homogeneous". The entry and exit of the market are completely free; The many goods offered by various producers are different, but there is no essential difference. Guangming Milk Factory produces dairy products. Besides Guangming Milk Factory, there are other brands of milk, such as Yili and Meiji. So the product is substitutable. 上图Process Report by严靖淳 Tina Yan LWS 10A班 LWShanghai 世界上最大的乳品单体公司光明乳业华东有限公司 ------世界上最大的乳品单体公司 Bright Dairy East China Co., Ltd ------ the world's largest dairy monomer company 投资14.21亿元，总占地面积155.079平方米，总建筑面积126.463平方米。 With an investment of 1.421 billion yuan, the company covers a total area of 155.079 square meters and a total construction area of 126.463 square meters. 生产线62条，日产量2600吨，酸奶700吨，巴氏奶700吨，UHT奶700吨，年产量60万吨 62 production lines, daily output of 2600 tons, 700 tons of yogurt, 700 tons of pasteurized milk, 700 tons of UHT milk, annual output of 600,000 tons 2021年5月28日，上海美高学校的同学们走进光明乳业工厂。参观乳制品生产流水线。 Students from Living Word Shanghai walk into the Guangming Dairy Factory on May 28, 2021.Visit the dairy production line LWShanghai 不同种类的乳制品乳酸菌饮料：小小光明乳酸菌饮料，光明藜麦牛奶饮品...... 牛奶饮品：巧克努力，一只椰子...... 新鲜牛奶：致优，优倍，鲜牛奶...... 酸奶：莫斯利安，健能...... 奶酪：片状奶酪，奶酪棒...... 奶粉：光明牧场...... 冰淇淋：光明奶砖，娃娃雪糕...... 植物饮料:植物活力，噜渴...... LWShanghai 酸奶流水线酸奶生产线设备是通过原料奶经过预处理并冷却到接种温度后，进-步的加工工艺要根据是生产凝固型、搅拌型、饮用型、冷冻型还是浓缩型酸奶而定。酸奶的组织状态和风味是决定酸奶质量的重要指标。酸奶车间的温度很高，大约在42摄氏度到43摄氏度，以保证酸奶成功发酵。 Yogurt production line equipment is through raw milk after pretreatment and cooling to inoculation temperature, step by step processing technology according to the production of solidification type, mixing type, drinking type, frozen type or concentrated type of yogurt. The texture state and flavor of yoghurt are important indexes to determine the quality of yoghurt. The temperature in the yogurt workshop is very high, about 42 to 43 degrees Celsius. To ensure the successful fermentation of yogurt. LWShanghai 常温奶流水线常温奶也称为UHT奶，即采用超高温瞬时灭菌技术（UHT）生产加工，并灌装入无菌包装内的牛奶。其生产工艺是在135～150摄氏度下加热2～3秒，并迅速回落至室温。瞬间灭菌在杀灭细菌和微生物的同时，能够最大限度地保护牛奶的营养和口味。常温奶通常采用无菌复合纸包装，无需冷藏和防腐剂就可以使牛奶在常温下拥有较长货架期。但由于高温杀菌，相对来说免疫球蛋白的数量会比鲜奶低。 Normal temperature milk, also known as UHT milk, is the milk produced and processed by ultra-high temperature instantaneous sterilization technology (UHT) and filled into aseptic packaging. It is produced by heating it for two to three seconds at 135 to 150 degrees Celsius and then rapidly returning to room temperature. Instant sterilization can protect the nutrition and taste of milk to the maximum extent while killing bacteria and microorganisms. Room temperature milk is usually packaged in sterile composite paper, which allows milk to have a long shelf life at room temperature without refrigeration and preservatives. However, due to pasteurization, the amount of immunoglobulin is relatively lower than that of fresh milk. LWShanghai 鲜奶流水线鲜奶是所有牛奶中品质最高的，含有丰富的免疫球蛋白。成本也最高。鲜奶运用的是唯绿包装（evergreen）而不是利乐包装。鲜奶都在晚上12点开始制作，第二天运出厂，再分发到各个超市。鲜奶只有7天保质期。 Fresh milk is of the highest quality among all milks and is rich in immunoglobulin. It also costs the most. Raw milk is packaged in Evergreen, not Tetra Pak. Fresh milk is made at 12 PM, shipped the next day and distributed to supermarkets. Fresh milk has a shelf life of only seven days. LWShanghai 回收?? 小小的利乐包装蕴含了大秘密。喝完牛奶，牛奶盒回收分四步： After drinking milk, milk cartons are recycled in 4 steps: 1喝完倒空 drink and empty 2掀起四角 Raise the corners 3压扁包装 Flatten packaging 4投递回收 Delivery and recycling LWShanghai 杀菌三种方法 three types 1 低温长时杀菌(简称LTLT) Low Temperature Long Term Sterilization (LTLTT) 2 高温短时杀菌(简称HTST) High temperature short time sterilization (HTST for short) 3 超高温瞬时杀菌(简称UHT) Ultra-high temperature instantaneous sterilization (UHT for short)
