Passion fruit storage simulation experiment device and experiment method thereof

Abstract

The invention discloses a passion fruit storage simulation experiment device and an experiment method thereof. The passion fruit storage simulation experiment device comprises a fresh-keeping box, a temperature sensor, an environment heating device and a heating and refrigerating device. The temperature sensor is installed in the fresh-keeping box, the environment heating device is installed outside the fresh-keeping box, layering partition plates for containing passion fruits are arranged in the fresh-keeping box, infrared geminate transistors for detecting and placing passion fruits are mounted on the side wall of the fresh-keeping box between the adjacent layered partition plates, and the heating and refrigerating device is mounted at the top of the fresh-keeping box. According to the passion fruit storage simulation experiment device, passion fruits can be stored through gradient heating and cooling, the temperature of a storage chamber is prevented from being suddenly decreased orsuddenly increased through gradient heating and cooling, water vapor in the storage chamber is prevented from being condensed into water drops on the surfaces of the fruits, growth and reproduction of microorganisms are effectively prevented, rotting and deterioration of the whole fruits due to dip dyeing are avoided, and therefore a good storage effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of passion fruit storage, and relates to a passion fruit storage simulation experimental device and an experimental method thereof. Background technique [0002] At present, the storage methods of passion fruit at home and abroad are roughly divided into two types: natural cooling storage and artificial cooling storage. [0003] Natural cooling storage is a simple, traditional, and affordable storage method. Ventilated cellar storage is a natural cooling storage method commonly used by people. This is a storage method that uses the low temperature of the external natural environment to adjust the temperature and humidity of the storage environment. Although it will be subject to regional and seasonal restrictions when it is used, and the storage temperature cannot be controlled at the expected temperature. However, this storage method is still widely used in our country. [0004] Artificial cooling storag...

Problems solved by technology

However, as far as the current technological development is concerned, the economic cost of controlled atmosphere storage is high, and the complexity of operation experience and management experience is high.

At present, the spontaneous controlled atmosphere storage is widely used in our country, that is to use the respiration of passion fruit itself to absorb and consume the oxygen in the storage room, thereby releasing carbon dioxide to achieve the effect of controlled atmosphere. This storage technology is certainly not as good as the real controlled atmosphere storage. Technology, but easy to operate, lower economic cost and less risk

[0006] Above-mentioned method all can not satisfy the fresh-keeping of passion fruit

[0007] In addition, the temperature measurement of the passion fruit refrigerator is generally a single point temperature measurement, which cannot fully reflect the main temperature distribution of the entire space of the refrigerator, and this single temperature measurement point is often unable to be placed in the center of the space, so it is impossible to obtain the temperature of the center of the space. spot temperature
