Discussion on juicer technology and performance
Posted 1 year ago in Science and Technology.
According to Gallup, a well-known market research agency in USA, there are around 20 million home juicers on the stock market each year. Household juicer is so popular, it is green and nutritious, that it means the high quality of life in a way.
Juicers can make a quick and flavorful glass of juice full of vitamins, and it also have some pain points for consumers. Mainly reflected in the noise, juice rate, clean the filter.
The industry standard for juicer noise is less than 80 decibels, and the mainstream juicer noise test is in the 60-70 decibels. The actual feeling of the consumer, when the machine is turned on, the sound is like a beast that has been roaring. In 2012, Philips made a major breakthrough in product structure design. It was the first one to try to reverse the design of filter basket, which successfully reduced the noise by 30%. The noise test data was 45-55 decibels.
The rate of juice is determined by three factors, blade structure, filter Angle and metal cone mesh. The performance is a process of repeated testing. In 2013, SEB engineers tested a new juicer using a truckload of carrots for three months before they came up with satisfactory results of the juicer strainers. Different fruit juice rate is not the same, generally, watermelon juice rate is the highest 85%, carrot juice rate is the lowest 55%. Different types of juicers have different performance. However, the design of a juicer that is obsessed with juice rate can easily fall into the trap. For example, if the juicer filter mesh is designed to be larger, the juice rate will naturally increase, and the pulp will also leak into the juice, ruining the taste. At present, the major kitchen appliance brands, in the field of high-end juicer, always design the filter mesh smaller and make the juice taste more delicate. On the other hand, it also has a good performance in juice rate.
The problem of filter cleaning is really a difficult problem to solve. At present, the fruit juicer filter of the mainstream juicer on the market adopts the metal etching process. The mesh produced by it is observed under a 500 times magnifying glass. The edge of the mesh is not smooth, which will prevent the pulp fiber from passing through. This accumulation of pulp fibers in the mesh results in difficult cleaning after use. Currently, there are two attempted solutions in the industry, one is an electric corrosion process, and the other is a micro-porous mesh process. The mesh of electric corrosion process is smooth, and it is slightly reduced difficult of cleaning, but costing high. Micro-porous mesh can be 60 mesh, mesh smooth, easier to clean, in addition to high manufacturing cost, the appearance of the juicer filter is lack of metal texture, only in a few areas such as the Middle East markets recognized.
In recent years, the industry has also introduced alternative products, such as slow juicer. The product solved the above three problems of the juicer, but the taste of the juice was significantly reduced. In general, with the development of the industry, major brands have launched a series of multi-functional new categories, such as strong blender, mixer stand, etc., but the juicer's excellent performance in juice is irreproachable.
