Abstract

The invention relates to a novel supermarket vegetable fresh keeping selling device, which comprises a box body, wherein small vent holes are arranged in the box body, a small-size air conditioner and a spraying device are arranged in the box body, and support materials filled with tap water, sterilization mud or nutrient solution are underlaid at the bottom of the box body. Vegetables with treated roots are placed on the support materials so that the root parts or the stem parts of the vegetables are in contact with the tap water, the sterilization mud water or the nutrient solution, so the moisture and the nutrient consumed in the vegetable selling process because of the transpiration and the respiration are supplemented, and the goal of prolonging the preservation time of the vegetables is reached. A proper amount of potassium permanganate or calcium peroxide is added in the tap water, the sterilization mud water or the nutrient solution, the sterilization and disinfection effects can be realized, and the oxygen can be slowly released for the root aspiration. The box body and a cover are made of transparent materials, the small vent holes and windows are arranged in the box body and the cover, and the windows are convenient for ranging, placing or taking the vegetables. The temperature in the box is regulated to 16 to 20 DEG C, and the humidity is regulated to 80 to 90 percent through the regulation of the small-size air conditioner and the spraying device.

Description

technical field [0001] The invention relates to a fresh-keeping device, in particular to a novel fresh-keeping and selling device for vegetables in a supermarket. Background technique [0002] At present, green leafy vegetables in supermarkets are generally placed directly on shelves or counters for sale (some supermarkets are equipped with sprinkler devices). It is easy to lose water, wilt, rot, and deteriorate, so that the fresh-keeping time of green leafy vegetables is very short. After overnight, they will deteriorate and cannot be sold. This not only increases the operating cost of the supermarket, but also causes a waste of vegetables. [0003] The Chinese patent No. ZL 200620000774.5 is a utility model patent, which discloses a multifunctional vegetable fresh-keeping box. It places nutrient soil filled with nutrient solution at the bottom of the box, and above the nutrient soil is provided with horizontal and vertical grids, and vegetables pass through the grids. The...
