Embodiment 2

[0059] A method for preventing and controlling mango anthracnose based on plasma active hot water, comprising steps:

[0060] S1. A hot water heating device is used to prepare hot water.

[0061] Preferably, the water source is tap water. After flowing into the hot water pool and submerging to a certain height, the electric heater works until the temperature of the hot water is 50-55° C., and the temperature probe detects the temperature of the water flow in the pipeline to determine.

[0062] S2. Treating hot water with a plasma treatment device to prepare plasma-activated hot water.

[0063] The plasma treatment device is an atmospheric pressure plasma jetting device. The plasma treatment in this example is intermittent treatment. The specific treatment parameters are: the gas source is air, the gas flow rate is 5L / min, the working frequency is 10kHz, the voltage is 60kV, and the treatment gap The plasma treatment time is determined by the specific water volume in the hot w...

Embodiment 3

[0075] A method for preventing and controlling mango anthracnose based on plasma active hot water, comprising steps:

[0076] S1. A hot water heating device is used to prepare hot water.

[0077] Preferably, the water source is tap water. After flowing into the hot water pool and submerging to a certain height, the electric heater works until the temperature of the hot water is 50-55° C., and the temperature probe detects the temperature of the water flow in the pipeline to determine.

Abstract

The invention belongs to the field of fruit and vegetable preservation, and relates to a device for preventing and controlling mango anthracnose based on plasma active hot water. The device comprises a plasma treatment device, a hot water heating device, an atomization spraying device, a conveying belt device, a composite preservative soaking device and an air drying and modified atmosphere packaging module, the plasma treatment device is located above the hot water heating device, and the hot water heating device is connected with the atomization spraying device through a pipeline; the atomization spraying device is located above the conveying belt device, the composite preservative soaking device is located at the tail end of the conveying belt device, and the air drying and modified atmosphere packaging module is located behind the composite preservative soaking device. According to the invention, plasma and hot water are effectively combined, and the combined treatment mode can remarkably inhibit the lesion development of mango anthracnose, so that the nutritional value and sensory quality of mangoes are improved. The invention further provides a method for preventing and controlling mango anthracnose based on plasma active hot water.

Description

technical field [0001] The invention belongs to the field of fresh-keeping of fruits and vegetables, and relates to a device and method for preventing and controlling mango anthracnose based on plasma-activated hot water. Background technique [0002] Mango is a tropical seasonal fruit, rich in vitamins, proteins, carotene and trace elements, etc. It is known as the "king of tropical fruits" because of its high nutritional value and unique flavor. my country is the second largest mango producing country after India, and now has more than 40 mango varieties, mainly produced in Guangdong, Guangxi, Guizhou, Yunnan, Fujian, Sichuan and other provinces. However, under high temperature and humidity production, storage and transportation conditions, mangoes are susceptible to invasion and infection by various pathogenic fungi, resulting in decline in fruit quality and loss of market value. Wherein anthracnose caused by anthracnose fungus (Colletotrichum) is the most serious postha...
