Introduction
自古以来,阳光就被用作能源。据信,太阳能的知识存在于一些最古老的文明中,如希腊人和罗马人,尽管他们没有将其用于烹饪。食物可以利用阳光制作——这一原理出现得晚得多,大约在19世纪70年代发展起来。太阳能炊具是一种低技术设备,可以以非常低的成本制造,但它有其优点和缺点。
What is a solar cooker
太阳能炊具可以定义为一种可以使用阳光直射作为能源并用于烹饪的设备。它的工作原理是将阳光转化为热能(Mepits,2022)。简单地说,阳光加热锅,将能量转化为热能,用于烹饪食物,或对饮料或任何其他食品材料进行巴氏杀菌(Thirugnanam,Karthikeyan&;Kalaimurugan,2020)。
光能和太阳能炊具材料之间的相互作用过程有助于将能量转化为热量,这一过程被称为传导。

Types of solar cookers
太阳能炊具的基本结构由平底锅或锅组成,镜子是必须的(Omara等人2020)。然而,根据太阳能炊具的结构,主要有两种类型的太阳能炊具,箱式和抛物面
Figure 2: Types of solar cooker
Box Type solar cooker
在这种类型的太阳能炊具中,热量被反射到一个盒子里,然后被顶部的玻璃捕获,产生温室效应,在这个过程中,热量就产生了。使用时,这种热量会使食物煮熟(Researchgate,2022)。
最常用的太阳能炊具是箱式的。它有一个基本结构,三个主要部件用于制造太阳能炊具。一个金属盒子从里面漆成黑色,非常重要的是一块玻璃板,一个可以作为反射器的平面镜。
Parabopc type solar cooker
在抛物面型太阳能中,烹饪器具所在的地方,热量会集中在一个点上。太阳能炊具加热,有助于烹饪。太阳能集热器用于烹饪食物和对水进行巴氏灭菌(Omara等人2020)。
它可以在很短的时间内加热。这种类型的太阳能炊具自古以来就被使用。人们认为,弯曲镜子的想法来自希腊和罗马文明。

Advantages and disadvantages of solar cooker
由于阳光不能直接工作,它需要热转换,因为光波与太阳能炊具的分子相互作用(Thirugnanam,Karthikeyan&;Kalaimurugan,2020)。太阳能炊具的许多优点使其广受欢迎;然而,它也有缺点。
Advantages of solar cooker
太阳能炊具可以以最低的成本和更少的部件制造。这就是它如此受欢迎的主要原因(Researchgate,2022)。由于它不需要燃料,一方面可以节省资金,另一方面可以降低污染水平,改善我们的环境。太阳能是免费提供的,任何人都可以使用,而且非常低的管理成本使每个人都能负担得起。
Disadvantages of solar cooker
由于太阳能炊具只能使用太阳能,因此在雨天甚至室外多云时,它的效率会降低(Thirugnanam,Karthikeyan&;Kalaimurugan,2020)。与烤箱和煤气相比,在太阳能炊具中烹饪是一个非常耗时的过程。在准备厚盘子的时候,使用太阳能炊具变得很困难。即使是强风也会阻碍烹饪过程。
Significance of solar cooker
太阳能炊具是最简单的设备,可以用来烹饪任何食物。由于它不需要生火,所以使用安全,对环境友好。对许多人来说,它更容易使用,因为它价格低廉(Mepits,2022)。它只是利用太阳的能量,在你需要的温度下烹饪。温度可以控制,你可以根据需要使用它来烹饪食物。太阳能炊具可以简单地让紫外线进入其中,并很容易地将其转化为无法逃逸的光线。
Conclusion
太阳能炊具是通过使用太阳能来烹饪食物的。它的反射板用于将光线聚焦在太阳能炊具内的黑色锅上。利用太阳能烹饪可以使整个过程变得更简单。它非常有益,因为它有助于我们节省燃料,减少环境污染。许多人仍然不知道这个简单而便宜的过程;他们仍然使用烤箱烹饪蔬菜和其他食物。当太阳能等资源无限供应时,最好用太阳能炊具做饭。
FAQs
问题1.太阳能炊具是如何工作的
答:太阳能炊具将阳光转化为热量,可用于烹饪任何食物或液体。简而言之,太阳能炊具是在太阳能的帮助下用来烹饪的。
Q2.太阳能炊具有哪些类型
答:通常,市场上有两种类型的太阳能炊具,即箱式和抛物面。还有一些更像箱式烤箱、抛物线炊具和管状炊具。
Q3.为什么我们在太阳能炊具中使用黑色
答:由于黑色是一种很好的导体,可以吸收更多的热量,所以它是太阳能炊具最合适的颜色。黑色表面有助于更快地加热设备。
