Ultrasonic wave atomization humidification sterilization device for fruit and vegetable freshness retaining transportation and achieving method of ultrasonic wave atomization humidification sterilization device

Abstract

The invention discloses an ultrasonic wave atomization humidification sterilization device for fruit and vegetable freshness retaining transportation and an achieving method of the ultrasonic wave atomization humidification sterilization device. The device comprises a basis circuit module, a master control module, an executing mechanism and a signal acquiring module; the basis circuit module comprises a power supply circuit, a crystal oscillator clock circuit and a reset circuit; the master control module comprises a central controller, a program burning circuit, a keyboard circuit, an LCD display and alarm circuit and a load control circuit; the executing mechanism comprises an ultrasonic wave vibrator, a magnetic valve, a water pump, a liquid level keeping device, a purified water box, a medicament box, a liquid mixing box, an atomization box and a draught fan; the signal acquiring module comprises a relative humidity sensor and a liquid level sensor. The ultrasonic wave atomization humidification sterilization device is stable to operate and low in failure rate, an upper limiting value and a lower limiting value of relative humidity are set and controlled, switching on and switching off of the device are controlled by judging whether the relative humidity of the environment is greater than the upper limiting value and the lower limiting value, and the relative humidity of the environment is controlled within certain threshold values. Meanwhile, repeated actions of the device in a short time are avoided, and the device is controlled stably.

Description

technical field [0001] The invention relates to the field of fresh-keeping transportation of fruits and vegetables, in particular to an ultrasonic atomization humidification and sterilization device for fresh-keeping transportation of fruits and vegetables and a realization method thereof. Background technique [0002] Relative humidity is an important factor affecting the quality of fruit and vegetable products during fresh-keeping and transportation after harvesting. Most fruits and vegetables require storage in a high humidity environment of 85% to 95%. At present, the cooling speed of fruit and vegetable fresh-keeping transportation equipment is often used as a measure, but the storage and fresh-keeping effect is still unsatisfactory, and the main factor is that the relative humidity is too low. Most of the domestic fruit and vegetable transportation equipment does not have relative humidity control equipment, and a small part uses floor sprinkler humidification or high...

AI Technical Summary

Problems solved by technology

The fresh-keeping transportation environment of fruits and vegetables has the characteristics of dense stacking of goods, narrow space, low temperature, high humidity, and severe vibration. The existing sterilization equipment is difficult to meet the harsh working environment of fresh-keeping transportation of fruits and vegetables.
