Living leaf vegetable vending machine and management method

Abstract

The invention provides a living leaf vegetable vending machine and a management method. The living leaf vegetable vending machine comprises a closed interlayer structure, a bottom suction water charging system, an electrothermal film constant temperature system, a CO2 concentration control system, a red blue LED light source system, a lifting harvesting structure, and an industrial control tablet PC. Through sensors and a relay, temperature, air fertilizer content, illumination intensity, culture medium water content and other necessary environmental factors for leaf vegetable crops growth in the closed interlayer structure are automatically optimized, so as to achieve objectives of living leaf vegetable storage, freshness preservation energy consumption reduction, and automatic selling. The vending machine uses a microenvironment control idea, and preserves to-be-sold leaf vegetables in a plant normal growing form, so commodity keeps fresh all the time in a selling period. The vending machine equipment does not need a high-energy-consumption compression refrigeration mechanism, and realizes 24 h automatic selling of fresh leaf vegetables. The vending machine is suitable to be used for leaf vegetable automatic selling in various hotels and dining places, high-end residence communities, office buildings, and serviced apartments and other indoor places.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to a living leaf vegetable vending machine and a management method.
