The growing demand in the fruit market has not only driven the deep processing industry of fruits and vegetables, but also brought opportunities for fruit and vegetable processing equipment. The biggest feature of preserved fruit is that it serves as a dry product, replacing the fresh fruits and vegetables to ensure people's nutritional intake. It is reported that the production of preserved fruit in ancient times was entirely manual and extremely painstaking. Today, the modern fruit production system has already bid farewell to the manual cooking mode and has gone on a track of high speed and intelligence. All of its processing and production processes use high-tech equipment such as nuclear machines, pre-cookers, dryers, packaging machines, and sterilizers.

In addition to the cooking process, the most important thing is the fruit drying process. After the fresh fruits are picked from the branches, they are dried, processed, plucked, nucleated, sliced, and dried. During the drying process, the fruit's original flavor and proper size and shape should be maintained as much as possible. The dried fruit that has been soaked and boiled still needs to be dried again. It is dried at a constant temperature of 60-70°C for about 1 hour. The dried fruit is moderately soft and hard, and the water content is about 20-25%. The appearance color is bright and the sweetness is moderate.
The traditional drying methods of fruits and vegetables are greatly affected by weather conditions, and there is a problem of mildew or uneven drying. Secondary pollution occurs easily during the drying process, and the drying area and equipment are subject to multiple restrictions. Needless to say, the traditional drying process has not been adapted to the needs of modern production. Dryers and drying rooms have emerged. Compared with traditional drying methods, the “machine drying method†not only takes a short time, saves manpower, and reduces the cost. The dried fruits and vegetables are evenly colored, bright and clean, and their taste is particularly sweet.
The survey shows that, for example, for tomatoes, the purchase price for a kilo of tomato is 0.4 yuan, and 1 kilogram of dried tomato is dried for every 7 kilograms of tomatoes, and the selling price for one kilogram of dried tomatoes is 10 yuan to 11 yuan. Counting this account, drying equipment extends the industry chain and contributes to the deepening of the value-added space for fruit and vegetables.
At present, many fruit and dried fruit production enterprises in China are using fruit and vegetable drying equipment, but they are also facing some problems. For example, how to solve different product classification and drying, how to reduce nutrient loss in drying, how to make drying equipment more low-cost, environmental protection, etc., these issues need the joint efforts of the drying equipment industry. In the market environment where the preserved fruits and dried fruits lead the “fresh†snack foods, the construction and research and development of drying equipment are promising, and the market demand will also be worth looking forward to.
Modern fruit has gradually developed into an industry, becoming a part of the food industry and a branch of deep processing of fruits and vegetables. It is reported that only from January to May this year, Baoding's fruit exports reached 68 batches with a value of 2.228 million US dollars, a year-on-year increase of 119.4 billion, an increase of 126.2%, and the export volume showed a substantial increase. At present, China's Xinjiang, Jiangsu, Sichuan, and Guangzhou are all famous fruit-producing areas, and the preserved fruit is growing as a local specialty food. There are various kinds of fruits in tourist gifts.
