Sous-Vide: 这是多高的耗电量

by Tobias

苏式烹饪对许多人来说是一种有趣的烹饪方式,但应考虑到电力消耗。这个变体用于准备肉类、鱼类或蔬菜,动作轻柔,切中要害。

苏泊尔的典型耗电量

通过不断重新加热水,温度保持在同一水平–很长一段时间。

  • 一般来说,苏泊尔的耗电量随电器的不同而大不相同。这是因为功率在500瓦和2000瓦之间变化。功率越大,电流就越大,但水被加热的速度也越快。
  • 有一些苏式电视棒,只需放在水浴中,然后将里面的水加热到适当的烹饪温度,并保持在那里。有了这些–除了带有凹槽的特殊锅盖–锅的顶部是敞开的,这意味着更多的热量会泄漏,必须重新加热。当然,这也会造成更多的成本。然而,这些棒子非常节省空间,是一个相对便宜的开始。
  • 另一方面,一个替代方案是封闭式装置,其工作更加精确,而且顶部没有热量可以泄露。然而,这些当然是相当昂贵的购买。
  • 不过,基本上可以说,与传统的烹饪方法相比,苏泊尔的烹饪方式可以说是更加高效而不耗电的。这也取决于你在锅里或苏式烹饪机里装的水的数量和温度。
  • 在一个例子中,成本变得更加清晰。要用苏式烹饪牛扒,水浴的温度必须达到58摄氏度。牛排必须在水中漂浮2小时。
  • 仅就两小时的烹饪时间而言,平均需要约200瓦的功率来保持水的温度,并使其循环以确保各处的温度相同。这意味着要消耗约400瓦时,即0.4千瓦时(kWh)。
  • 按照37.3美分/千瓦时的电价(截至2022年7月),这导致成本略低于15美分。此外,还有进一步的费用用于水的初始加热。出于这个原因,在装水时,水应该已经尽可能地接近目标温度了。
  • 对于在普通电炉上煎牛排,人们可能会认为成本高于15美分。因此,如果水的初始加热不消耗太多能源,这种替代性准备甚至提供了潜在的节约。
