In the modern kitchen environment, the mechanical kitchen scale, as a key tool, plays an indispensable role. It provides professional chefs and family cooking enthusiasts with the ability to measure ingredients to measure ingredients, thereby ensuring the accuracy and consistency of the cooking process. However, environmental factors such as temperature and humidity have a significant impact on the performance and weight results of the mechanical kitchen scale. Understanding these influencing factors is essential for improving the quality of cooking.

The effect of temperature on mechanical kitchen scale
Temperature changes directly affect the material characteristics of the mechanical kitchen scale. Common scale materials include metal, plastic and glass. These materials will cause heat expansion or contraction under temperature changes. For example, metal components expand in high temperature environments, and they shrink in low temperature environments. This physical change may cause the pointer or scaled disk position of the scale to offset, which affects its weighing accuracy.
In addition, temperature can also affect the physical properties of ingredients. For example, the weight of butter at room temperature may be different from its weight in refrigeration. The butter in the low temperature state is harder, and may be compressed during the weighing process, resulting in inaccurate weight results. The density of the liquid will also be affected by temperature changes. When the temperature rises, the density of the liquid will usually decrease, which may cause changes in the weight results.
The changes in air density are also a factor that cannot be ignored. As the temperature rises and the density of the air decreases, this change may affect the weight of lightweight materials (such as flour, sugar, etc.). Lightweight materials are easily disturbed by air flow when weighing. Therefore, changes in temperature may lead to unstable reading, which will affect the accuracy of cooking.

The impact of humidity on mechanical kitchen scale
Humidity is also an important factor affecting the performance of mechanical kitchen scale. Many ingredients, especially dry powder (such as flour, sugar, salt, etc.), have certain hygroscopicity. In high humidity environments, these ingredients are easy to absorb water in the air, leading to an increase in weight. For example, flour may absorb moisture in a humid environment, and the reading when weighing may be higher than the actual weight. This phenomenon is particularly important during baking, because each gram in the formula may have a far -reaching impact on the quality of the final product.
In addition, excessive humidity may also cause some components of the mechanical kitchen scale to be moisture, especially metal components, and may occur in rust or corrosion. This not only affects the appearance of the scale, but also may damage its internal mechanism, which will affect the accuracy and service life of the scale. Therefore, maintaining the drying scale is an important measure to ensure its normal operation.
In high humidity environments, air liquidity is enhanced. This fluidity affects the weight result of lightweight materials, which may cause unstable reading. Lightweight materials may float due to air flow in a humid environment, which leads to uncertainty of weighing results.
