Fresh-keeping storage tray for fruit and vegetable

Abstract

The invention belongs to the technical field of storage of fruit and vegetable and particularly relates to a tray device capable of storing and keeping food such as granule fresh fruit and vegetable fresh for a long time. The tray comprises a tray bottom, breathable packing, a thin film, a tray body, inner concave edges, outer concave edges, handles, vent holes and fiber cloth. The inner concave edges are arranged at the edges corresponding to inner sides on the periphery of an upper opening of the tray body, and the outer concave edges are arranged at the edges corresponding to outer sides on the periphery of the bottom surface of the tray bottom. Hole-shaped handles of a concave structure are arranged on outer surfaces of two opposite lateral walls of the tray body. The through vent holes are distributed on the tray bottom, the fiber cloth of a breathable structure is laid at the bottom end in an inner cavity of the tray body, the breathable packing is laid on the upper surface of the fiber cloth evenly, the soft thin film is laid on the upper surface of the breathable packing, and the peripheries of the thin film and the fiber cloth are fixed on the lateral walls of the inner cavity of the tray body respectively. The fresh-keeping storage tray is simple and reasonable in structure, simple in manufacturing process, low in cost, safe and reliable in use, good in breathability and applicability and environmentally friendly.

Description

Technical field: [0001] The invention belongs to the technical field of fruit and vegetable storage, and relates to a tray device for long-term preservation and storage of granular fresh fruits and vegetables, which is used in low-temperature or constant-temperature environments such as fresh-keeping cabinets and cold storage to realize long-term stacking or storage of fruits and vegetables. . Background technique: [0002] At present, fruits and vegetables, as foods that are easy to shrink, perish, have a short shelf life, and strong seasonality, generally use drug treatment, sealed packaging, and cold storage to keep fresh for long-term storage. These existing methods will not only keep pesticides Residue, and due to the airtight airtightness, the ethylene released by breathing when the fruits and vegetables are bagged will accumulate in the bag, and ethylene is a fruit and vegetable ripening agent. Its existence and accumulation will promote the further ripening of refrig...

Problems solved by technology

[0002] At present, fruits and vegetables, as foods that are easy to shrink, perish, have a short shelf life, and strong seasonality, generally use drug treatment, sealed packaging, and cold storage to keep fresh for long-term storage. These existing methods will not only keep pesticides Residue, and due to the airtight airtightness, the ethylene released by breathing when the fruits and vegetables are bagged will accumulate in the bag, and ethylene is a fruit and vegetable ripening agent. Its existence and accumulation will promote the further ripening of refrigerated fruits and vegetables until they deteriorate, thereby shortening Increased freshness of fresh fruits and vegetables

In the prior art, in order to reduce the ethylene content in the frozen storage of fruits and vegetables, the respiration of fruits and vegetables is reduced by adding hydrogen-producing and oxygen-consuming devices, or the photosynthesis of fruits and vegetables is stimulated by adding light-emitting diode devices to prolong the preservation time of fruits and vegetables. However, due to the high technological content of these technologies , the cost is high, the operation is complicated, and it is difficult to realize it and cannot be applied on a large scale; cold storage adopts traditional methods such as loading baskets and stacking to store fresh fruits and vegetables, which reduces the release and accumulation of ethylene to a certain extent, but causes a large amount of water loss and shrinkage of fruits and vegetables Deformation, the preservation effect is significantly reduced, and the stacking structure is unreasonable, and the space utilization rate is low
