Description

Technical field: [0001] The invention relates to an intelligent fresh-keeping cabinet for fruits and vegetables in supermarkets. Background technique: [0002] Fruits and vegetables are fresh agricultural products, which have the characteristics of perishability, fragility, short postharvest lifespan, and easy aging or quality change during postharvest commercialization, resulting in a decline in their nutritional quality and commodity value. The loss rate of vegetables and vegetables due to limited storage conditions in the sales process is about 25-30%. At this stage, in supermarkets of all sizes in various cities in China, fruits and vegetables are generally sold on open shelves, and the overall temperature of the room is adjusted to ensure their freshness.

AI Technical Summary

Problems solved by technology

In recent years, although some fruit and vegetable fresh-keeping cabinets have appeared on the market, the current fruit and vegetable fresh-keeping cabinets are large in size, low in internal space, high in manufacturing cost, poor in sealing and fresh-keeping effects, short in fresh-keeping time, intelligent and humanized. The degree is low, and the purchasing experience effect is poor. Now, the purchase of fruits and vegetables in supermarkets generally varies according to the time of day. Purchases will be made between 5-7 pm, so there will be a peak of purchases between 8-9 am and 5-7 pm. During this period, the freezer will be frequently opened and closed, while the frequency of use in other time periods will decrease

The existing fresh-keeping cabinets all work in a single way, with high energy consumption and high noise. Under the above-mentioned use conditions for a long time, it is easy to have poor fresh-keeping effect and failure of fresh-keeping, poor working stability, and cannot meet the needs of shopping malls. The usage requirements of the purchase frequency have resulted in no promotion and use in various supermarkets.
