Development Trend of Fruit Food Weight Classifier
Traditional fruit food weight classifiers include two categories: volume classification and mass classification. Because the main purpose of grading is to unify the appearance specifications of products, thereby improving the sales grade of packaging, batch grading is widely used. What is the development trend of fruit food weight classifier? The following is a detailed introduction: 1. Volume classification equipment includes drum classifier, three-drum classifier and belt classifier. Their principles are similar, and both are screened through several grades of holes or crevices. 2. The weight classifier equipment has developed from the early mechanical weighing and classification form to the advanced high-speed dynamic electronic weighing and classification form. The fruit grading and waxing equipment of FMC Company in the United States is mainly used for the quality grading of citrus models. It can complete the cleaning, sorting, waxing, grading, packaging and other processes through the entire line. The fruit grading and packaging equipment of French MAF company can not only classify fruits and vegetables, but also use the principle of electron optics to classify the skin defects of fruits and vegetables. Full computer monitoring, high degree of automation. The modernization degree of food machinery is an important symbol to measure the development level of a country's food industry. With the progress of human society, people put forward higher requirements for the convenience, nutrition and safety of food. At the same time, the trend towards sustainable development makes it urgent to utilize the by-products of agro-processing and agricultural waste. According to production needs, different food machinery is designed. In the food processing industry, fruits of different sizes, shapes, densities, colors or qualities can be used to process different grades of finished products, not only making full use of various materials, but also making manufacturers more profitable. Fruit is graded before processing. At present, a more advanced and ideal weight classifier classification quality technology has been applied in the above-mentioned foreign enterprises, using new fruit classification quality equipment such as light curtain measurement technology or electronic scanning resolution technology. A light curtain detects running fruit and collects its outer dimensions. After the central processor calculates and compares it with the set grading size, it sends out instructions to drive the sorting mechanism to move and send the fruit to the appropriate grading ranks. Using computer vision processing systems such as electronic scanning and resolution, fruits and vegetables of different colors and shapes can be identified, and the skin defects of fruits and vegetables can be classified, thereby realizing online grading and quality classification. This is an intelligent machine integrating light, machine, electricity and programming. Compared with traditional pore size and mass classification methods, this classification technology is a qualitative leap, as it realizes a non-contact form of classification, which is accurate and high-speed.
