  • Dairy process - Industrial Refrigeration Danfoss
  • A - 乳品制冷

    • 原奶制冷:原奶经采集后需保持冷却
    • 牛奶采集:原奶过滤和提纯
    • 原奶储存:原奶储存温度必须为 +4º C 至 +6º C
    • 温度储存:巴氏杀菌之后,牛奶被临时性储存和冷却,以备随后超高温瞬时灭菌或包装处理
    • 无菌储存:巴氏杀菌奶和高温杀菌奶都必须储存于无菌低温环境中。

    制冷方式:氨、二氧化碳或冰水

    B - 巴氏杀菌

    巴氏杀菌是乳品加工的关键环节。巴氏杀菌后,热牛奶必须快速制冷到 4 °C 以下,以保持酶的活性。

    制冷方式:冰水可通过氨或二氧化碳热交换器实现制冷

    C - 凝结

    冰淇淋混合物通过搅拌和空气得以冷冻,从而形成冰晶并体积膨胀。

    制冷方式:冷凝机用于温度为 -6 °C 至 -9 °C的制冷

    D - 硬化

    经过填充和包装,冷冻冰淇淋必须保持冷冻温度,从而塑形和硬化。

    制冷方式:氨或二氧化碳速冻机

    E - 发酵、制冷和成熟

    发酵是酸奶生产和加工中的关键环节。酸奶的口感取决于乳酸发酵剂,它会受发酵温度影响;冷却工艺可以减少微生物和酶的活性。为了避免过量产酸,成熟过程可以进一步改善口味。

    凝固型酸奶:经过24小时发酵的凝固型酸奶在出售前必须立即在 0 °C 至 +4 °C 保存以增加酸度。

    搅拌型酸奶:经过发酵的搅拌型酸奶在存储前必须冷却到 +10 °C 至 +20 °C,且在 0 °C 到 +7 °C之间进行成熟和储存。

    制冷方式:冰水用于制冷,这可以通过氨或二氧化碳 板式热交换器实现。

    F - 制冷储存

    包装后,经过巴氏杀菌的牛奶必须储存于 +4 °C 的冷藏室中,从而确保牛奶品质。

    • 制成的酸奶产品必须储存在 0 °C 至 +4 °C,从而保持适当的酸性和避免变质
    • 制成的冰淇淋产品必须储存在 -24 °C 至 -28 °C,从而保持所需硬度和抑制细菌生长

    制冷方式:使用氨或二氧化碳的冷藏室的存储
