中文简体Electric juicers are indispensable equipment in modern kitchens, and their performance directly affects the quality and efficiency of juice extraction. In this equipment, the blade is the core component, and its design and material selection are crucial, which is directly related to the taste of the juice and the retention of nutrients.
Selection of blade material
The blade material is a key factor affecting its performance and durability. At present, stainless steel and carbon steel are the two main materials used in the market. Stainless steel blades are widely used due to their excellent corrosion resistance and wear resistance. It can resist the erosion of acidic and alkaline substances and is suitable for squeezing various fruits and vegetables. In addition, stainless steel blades are easy to clean, effectively reduce bacterial growth, and ensure the hygiene of the juicing process.
In contrast, although carbon steel blades are outstanding in sharpness and cutting effect, their easy rust and difficult cleaning make them relatively less used in juicers. Therefore, for home users, stainless steel blades are more ideal and can provide more stable performance and longer service life.
The influence of blade shape and design
The shape and design of the blade directly affect the cutting efficiency and effect. Common blade designs include flat blades, curved blades, and serrated blades. Flat blades are usually used for basic cutting and juicing, and are suitable for processing soft fruits such as watermelon and oranges. Their simple design can effectively cut ingredients into small pieces for easy juicing.
The curved blade design better adapts to the shape of the ingredients, especially when processing harder fruits and vegetables, such as carrots and apples, the cutting angle of the curved blade can significantly improve the efficiency of juicing. Serrated blades are suitable for processing fibrous ingredients, such as celery and ginger. The serrated design can easily cut the fibers and ensure more thorough juice extraction.
Importance of blade sharpness
Blade sharpness is an important factor affecting juicing efficiency. Sharp blades can quickly cut ingredients and reduce friction, thereby reducing the degree of oxidation of juice. When choosing a juicer, consumers should pay attention to the sharpness of the blade and its design process. Some high-end brands use laser cutting technology to ensure the sharpness and consistency of the blade, thereby improving the effect of juicing.
Blade speed and power system
The speed of the blade is closely related to the power system of the juicer. High-speed blades can complete cutting and juicing in a short time, but may cause an increase in oxidized substances in the juice. Centrifugal juicers usually have a higher speed, while slow-pressing juicers squeeze at a lower speed to reduce oxidation and retain more nutrients. When designing blades, manufacturers need to find a balance between speed and juicing efficiency to ensure that the taste and nutrients of the juice are retained to the greatest extent.
Blade safety design
Safety is essential in juicer design. When the blade runs at high speed, improper design may cause accidental injury. Therefore, many juicers are designed with a protective cover around the blade to prevent users from touching the blade during operation. In addition, the blade should also be fixed in a way that ensures that it will not loosen or fall off during use, further improving user safety.
