Centrifugal fruit and vegetable air-conditioning preservation box

Abstract

The invention discloses a centrifugal fruit and vegetable air-conditioning preservation box, which comprises an outer-layer box body, an outer box body door, a rotating shaft, an inner cavity, an inner cavity door, a plurality of closable air windows and a plurality of groups of condensation pipes, wherein the outer-layer box body is cylindrical; the outer box body door is arranged on the outer-layer box body; the rotating shaft is arranged in the center of the bottom in the outer-layer box body; the inner cavity is cylindrical, and the center of the outside bottom is arranged on the rotating shaft; the inner cavity door and the closable air windows are formed on the inner cavity; and the plurality of groups of condensation pipes are arranged on the inner peripheral surface of the outer-layer box body. In the centrifugal fruit and vegetable air-conditioning preservation box, the inner cavity provided with the closable air windows rotates to force air in the box to flow, and the air in the inner cavity is exchanged with air in an interlayer through the closable air windows, so the cold damage possibly caused by direct contact of fruits and vegetables and strong cold air can be avoided, and the air in the whole preservation box is distributed uniformly; therefore, the preservation effect is good.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning fresh-keeping, and in particular relates to an air-conditioning fresh-keeping device. Background technique [0002] Fruits and vegetables are living organisms before and after picking, and a series of biochemical reactions are carried out inside them, the most important of which is respiration. The aerobic respiration of fruits and vegetables after harvesting is characterized by the decomposition of carbohydrates such as sugar and fruit acid stored in the tissue cells of fruits and vegetables, producing carbon dioxide, water vapor, heat and some compounds. The stronger it is, the faster it will be consumed, the earlier the ripening period, and the shorter the storage time. [0003] With the development of society and the continuous improvement of living standards, people's demand for cross-regional and off-season high-end fruits and vegetables is increasing. However, as we all know, due ...

Problems solved by technology

At present, the commonly used modified atmosphere fresh-keeping storage system mainly includes refrigeration units, nitrogen generators, air compressors, humidifiers, sensors, controllers and modified atmosphere fresh-keeping stores; among them, the modified atmosphere fresh-keeping stores can be divided into three types according to the construction method: the first The type is a prefabricated controlled atmosphere warehouse, and its enclosure structure is made of steel plates with triple functions of heat insulation, moisture resistance and airtightness. The advantage is that the construction speed is fast and the appearance is generous, but the disadvantage is that the cost is slightly higher

The second type is brick-concrete controlled atmosphere storage, that is, civil construction storage, which is built with traditional building insulation materials, and the interior is treated with polyurethane spraying. Although the construction cost of this kind of air conditioning storage is relatively low, the disadvantage is the construction period Long, and the airtight effect is difficult to meet the requirements

The advantage of this kind of air-conditioned storage is that it is simple and practical, and the construction period is short, but the disadvantage is that the airtight material needs to be replaced regularly, and there is a certain difference in internal and external temperatures.

In addition, the above three types of controlled atmosphere storage have a common disadvantage that the position of the fruits and vegetables placed in the airtight space is fixed, and the positions of the condensation pipe and the gas injection port installed inside the controlled atmosphere storage are also fixed. There is no air forced circulation equipment inside, so the fluidity of the air is not good. As a result, although the storage time of the same batch of fruits and vegetables in the controlled atmosphere storage is the same, the storage effect is different due to the different storage positions.
