Nowadays, as people's living standards improve, they are more respected for high-quality consumption. Price is no longer a major factor affecting people’s purchases. More people are paying attention to the quality of goods when purchasing goods. Data show that there are about Ninety-nine percent of the fruits are used for fresh food. How to differentiate the quality of these fresh fruits to meet people's demand for high quality fresh fruits? This requires the post-harvest commercialization of fresh fruits, and the general commercial processing of fruits after harvest. There are multiple processes such as selection, grading, cleaning, and packaging. Among them, grading is an important means of distinguishing the quality of fresh fruits. Sorting equipment as the main force of grading has recently become more refined and close to consumer tastes.
Sorting equipment development towards refinement
Before the sorting equipment could not appear, sorting was carried out by fruit growers. Often, the sorting of fresh fruits was of different sizes and appearance. In addition, when consumers purchased such fresh fruits and vegetables, Often only by experience, by luck, because experience is not enough to taste bad fruit is common.
Driven by the desire to spend more money and do not want to eat unpalatable fruits, intelligent sorting equipment was born. The sorting criteria for such fruit sorting equipment are not limited to appearance, weight, and size sorting. It also shows intuitively the indicators such as sugar-acid ratio and internal defects of fruits. At present, intelligent sorting equipment capable of finely sorting fresh fruits is equipped with near-infrared spectroscopy, and the absorption of different components in fruits is achieved by near-infrared light. , Reflection, scattering, etc. The determination of the internal content of fruit. This method does not damage the fruit skin when inspecting the internal quality of the fruit, and is more intuitive and accurate to the internal composition of the fruit.
However, for durian-like fruits with excessively thick outer shells, the penetrating power and inspection accuracy of near-infrared spectroscopy equipment cannot be effectively guaranteed. The applicability of refined sorting equipment needs to be further strengthened.
Sorting equipment works hand in hand with packaging machinery to cater to consumers
Fresh fruit will eventually flow to consumers, so consumers' tastes will have a greater impact on the sorting process. Sorting fresh fruits that cater to consumers' tastes can be more competitive in the market sales process. In traditional concepts, The higher the fruit's sweetness, the lower the acidity the closer it is to being able to get close to the consumer, but this is not a conclusion drawn from scientific research. It is understood that there are scientific research institutions that are interested in the taste of fruits and develop different acids. Sweet sugar test sugar, consumers can measure their own preferences to eat sugar.
It is only the first step to measure the taste preferences of consumers. Next, sorting machines and packaging machines need to work together to achieve accurate understanding of consumer tastes. Because the differences in taste among individuals are greater, the sorting line is based on sweetness and sweetness. After sorting the fruits in detail, the packing machine can then label the fruits with the same acid sweetness and sweetness, and it can produce different fruits suitable for consumers' tastes. This kind of sorting and packing process is more complicated, and there are few attempts in all parts of our country. But as A sorting method that accurately grasps consumer tastes, its future prospects are worth looking forward to.
According to statistics, in developed countries, 90% of fruit picking is used for commercial processing and deep processing operations. Food machinery and equipment are indispensable. But in China, this proportion is only 20% to 30%, indicating that China is in the field of fruit processing. There is still a huge gap. Food machinery and equipment have huge opportunities in this. Fruit sorting equipment is a basic equipment in the process of fruit commercial processing and deep processing. It also needs to focus on its own research and development, and actively explore more suitable development paths.
