Abstract High temperature cooking operations like frying, roasting and baking using solar energy are normally carried out at the focus of parabolic dish concentrators. This leads to heat discomfort, risk of burns or eye damage to the user. A device which stores latent heat in a phase changing eutectic mixture called “solar salt” was designed and tested, which would enable its storage in an insulated container, and cooking in the shade of a kitchen when needed. It was able to successfully store heat at its melting point of 220 °C in a charging time of 110 min. Frying temperature of 170 – 180 °C for the oil was easily obtained during indoor cooking and 0.25 kg of potato chips were fried in 17 min from one charge of heat, while a total of about 0.6 kg of rice was cooked in two successive batches from one charge, taking 20 min each.

利用日光盐进行高温烹调的蓄热式太阳灶的研制

摘要 使用太阳能的油炸、烘烤和烘烤等高温烹饪操作通常在抛物面聚光器的焦点处进行。这会导致用户感到热不适、灼伤或眼睛损伤的风险。设计并测试了一种将潜热存储在称为“太阳能盐”的相变共晶混合物中的装置，该装置可以将其存储在绝缘容器中，并在需要时在厨房的阴凉处烹饪。它能够在 110 分钟的充电时间内成功地将热量储存在 220°C 的熔点。在室内烹饪时，油的煎炸温度很容易达到 170 – 180 °C，一次加热可在 17 分钟内炸出 0.25 公斤薯片，而在连续两批加热后，总共煎了约 0.6 公斤大米。一次充电，每次需要 20 分钟。
