Problems solved by technology

The temperature coefficient Q of most agricultural products 10 2 to 3, that is, every 10°C increase in temperature will increase the postharvest physiological metabolic aging rate by 2-3 times. However, during storage in traditional cold storage, the temperature fluctuates greatly due to operations such as storage, inspection, etc., which may easily lead to condensation on the surface of agricultural products. , to promote the phase transition of the cell membrane, which in turn leads to the rapid aging and decay of agricultural products
At present, there is no fresh-keeping store that can guarantee the trace fluctuation of temperature and gas during storage, so as to meet the needs of agricultural products to maintain a high level of commodity value continuously and stably.

Embodiment Construction

[0019] The structure of the fruit-vegetable phase-temperature-modulated-atmosphere fresh-keeping store of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] see Figure 1 ~ Figure 3 , the fruit and vegetable phase-temperature-adjusted-atmosphere preservation storehouse of the present invention comprises: coat storehouse 2, the inner cover storehouse 4 that is arranged in the coat storehouse 2 and the buffer zone 6 that is formed by the space between the coat storehouse 2 and the inner cover storehouse 4. The number of inner jacket storehouses 4 depends on the needs, and one or more can be set. In addition, in order to realize the exchange and conversion between the inner and outer cold and hot gases of the inner jacket storehouses 4, the bottom of the inner jacket storehouses is also formed by the ground dragon 8. Ventilation passage; The motor 7 that provides power is installed in the bottom of the buffer zone.

Abstract

The invention discloses a phase temperature controlled atmosphere fresh-keeping storehouse for fruits and vegetables. The storehouse comprises an outer sleeve storehouse, an inner sleeve storehouse and a buffer area formed by a space between the outer sleeve storehouse and the inner sleeve storehouse. The walls of both the outer sleeve storehouse and the inner sleeve storehouse are of sandwich structures; a ventilation port communicated with the buffer area is formed in the body of the inner sleeve storehouse; a fan is arranged on the ventilation port; a temperature control type cold air blower is arranged on the inner wall of the outer sleeve storehouse; an air circulating device and an air purifying device are arranged in the buffer area; one or more inner sleeve storehouses arranged; a ventilation channel is formed in the bottom of the inner storehouse. By guaranteeing the stabilization of inner and outer environments of the storehouse and avoiding the fluctuation of the temperature of storages, the life state of heat transfer non-mass transfer in the storage period of agricultural products is guaranteed, and therefore the fruits and vegetables are kept fresh.

Description

technical field [0001] The invention relates to a fresh-keeping store, in particular to a fresh-keeping store with phase temperature and atmosphere adjustment for fruits and vegetables. Background technique [0002] Temperature is one of the key factors in the preservation of agricultural products, which can significantly affect its post-harvest quality. The temperature coefficient Q of most agricultural products 10 2 to 3, that is, every 10°C increase in temperature will increase the postharvest physiological metabolic aging rate by 2-3 times. However, during storage in traditional cold storage, the temperature fluctuates greatly due to operations such as storage, inspection, etc., which may easily lead to condensation on the surface of agricultural products. , to promote the phase transition of cell membranes, which in turn leads to the rapid aging and decay of agricultural products. At present, there is no fresh-keeping store that can guarantee the trace fluctuation of ...
