Novel fruit and vegetable transport case, intelligent variable ventilation system and realizing method thereof

Abstract

The patent refers to the field of 'pumps for elastic fluids'. The invention discloses an intelligent variable ventilation system. The intelligent variable ventilation system comprises a control module, a frequency conversion module, a fan, a human-computer interaction interface and a signal acquisition module, wherein the human-computer interaction interface, the control module, the frequency conversion module and the fan are connected with one another sequentially; and the signal acquisition module is connected with the control module and the human-computer interaction interface respectively. The invention also discloses a method for realizing the intelligent variable ventilation system. In the method, the control module performs intelligent variable control on the rotating speed of the fan by a fuzzy control method according to signals acquired by the signal acquisition module, so that different ventilation rates are obtained. The invention also discloses a novel fruit and vegetable transport case. The novel fruit and vegetable transport case comprises the fan, a case shell and an internal case structure, wherein the case shell consists of an upper panel, a lower panel, a left panel, a right panel, a front panel and a rear panel; and the internal case structure comprises an air return duct, a fan mounting plate and an open pore partition board. The invention has the advantages of simple structure, convenience of processing, high intellectualization and the like, and contributes to improving the freshness-retaining quality of fruits and vegetables.

Description

technical field [0001] The patent of the present invention relates to the technical field of fruit and vegetable fresh-keeping transportation, in particular to a novel fruit and vegetable transportation box suitable for controlled atmosphere fresh-keeping, an intelligent variable ventilation system and its implementation method. Background technique [0002] After the transport box is filled with fruits and vegetables, the respiration and heat release of the fruits and vegetables will cause the ambient temperature in the box to rise, and the temperature rise in the box will further accelerate the respiration of the fruits and vegetables, which will easily lead to a decline in the quality of the fruits and vegetables and shorten the freshness period of the fruits and vegetables. At present, the traditional fruit and vegetable fresh-keeping transport box basically adopts a cuboid box body, and an air-conditioning evaporator is installed on the front of the box body, and the eva...

AI Technical Summary

Problems solved by technology

If the ventilation speed in the box is constant at a large value, it will easily lead to serious dry consumption of fruits and vegetables and reduce the quality of fruits and vegetables; if the ventilation speed in the box is constant at a small value, the environment in the box will be uneven and the preservation quality will be poor
