A food refrigerated and fresh-keeping storage box capable of controlling cooling capacity and air volume

Abstract

The invention discloses a food refrigeration and fresh-keeping storage box capable of controlling the cooling capacity and air volume, which comprises a storage box, a condenser, a thermal insulation board, an expansion and contraction assembly, and a cross air guiding box. The vertical lifting device and the horizontal moving device are respectively installed, and the inner sides are provided with insulation boards parallel to them. The cross air guide box is used for the connection of multiple sets of the expansion and contraction components, and the interior of the storage box is divided into four groups. Storage rooms, each group of storage rooms is provided with an independent exhaust channel, and a strip-shaped sliding cavity is provided on the insulation board, and a half-cross air guide box is embedded inside the strip-shaped sliding cavity, and the half-cross guide box The outer end of the expansion and contraction assembly of the air box is connected. A condenser is arranged inside the upper shell of the storage box. The gas channel is connected with the input end of the condenser, and a control screen is installed on the left side of the condenser.

Description

technical field [0001] The invention relates to the technical field of food refrigeration, in particular to a food refrigeration and fresh-keeping storage box with controllable refrigeration capacity and air volume. Background technique [0002] During the refrigeration process, the storage temperature, relative humidity and flow rate of the air are important condition factors for refrigeration. In practical applications, the specific conditions of these three are determined with the different types of food, the length of storage period and whether the food is packaged. The storage temperature, especially the temperature of the food itself, is the most important factor. For fruits, vegetables and shell eggs, it is generally better to be close to the freezing point. For example, the minimum storage temperature of bananas, pineapples, lemons, green tomatoes, cucumbers, and eggplants is 13, 7, 12, 12, 7, and 7°C, respectively. Below this temperature, low-temperature damage wil...
