Description

Fruit and vegetable cleaning machine

Technical Field

The invention relates to the technical field of agricultural equipment, in particular to a fruit and vegetable cleaning machine.

Background

The fruit industry is the third industry in the planting industry in China, and the current yield in China is rapidly increased every year. According to statistics: the fruit yield in China is increased from 10026 ten thousand tons to 2015 years in 2005 to 27381 ten thousand tons, and the total fruit yield is increased by 3 times in ten years. At present, the total yield of fruits in China is high, the quality of the fruits is improved due to the progress of grafting technology and is close to the international advanced level, but the total yield and trade volume of the fruits in China gradually have great contrast, and the root cause of the phenomenon is that the core competitiveness of the market is low due to the low commercial post-processing capacity of the fruits in China.

The market core competitiveness of fruit depends mainly on two factors, namely the quality of the fruit and the post-harvest treatment of the fruit. At present, the fruit quality of China is close to the international advanced level. The reason for the low international competitiveness of fruits in China is the insufficient postpartum processing capacity of fruits in China. The key point needed to be broken through is how to quickly and better realize the post-treatment processes of online, cleaning, waxing, drying and the like.

Meanwhile, with the development of Chinese economy, the urbanization process is accelerated, the living standard of people is steadily improved, and the service industry becomes the development key and becomes the first major industry for promoting the economic development. The catering industry in the service industry is more important, people have to eat as a day, people have a continuous pursuit for improving the quality of life, a consumption habit is formed by going out to eat and gathering, and the development of the catering industry tends to be normalized, scaled and interlocked. Food safety is a hot issue in the current society, so that the treatment of food materials such as vegetables and fruits is not enough by manual treatment, and how to realize the standardized treatment of food materials is an extremely important ring in food safety.

The existing cleaning machine products generally have the defects of single function, complex operation, high cost and the like, and cannot be popularized and used on a large scale.
