Food cleaning and sterilizing machine

Abstract

The invention discloses a food cleaning and sterilizing machine. The machine comprises a cleaning tank with an TiO2 plating layer on the inner surface, an ozone generating device, a centrifugal impeller, a gas diffusion plate, a motor, a linkage device and an isolation cover; the isolation cover is matched with the cleaning tank to form a chamber, the gas diffusion plate is disposed in the chamberto divide the chamber into a mixing chamber body and a gas dispersion chamber body, and the isolation cover is provided with a water inlet and a water outlet; the ozone generating device supplies gasto the gas dispersion chamber body; the centrifugal impeller is arranged in the mixing chamber body, and the motor is connected to the centrifugal impeller through the linkage device. The structure of the machine is simple, the gas supplied by the ozone generating device generates air bubbles through the gas diffusion plate, and the centrifugal impeller rotates to drive water flow to cut the airbubbles, so that the air bubbles are stripped without forming large bubbles, micro-nano air bubbles are formed, the solubility of ozone is increased, produced high-concentration ozone water forms hydroxyl radicals under the catalysis of the TiO2 plating layer, and under the double action of the ozone water and the hydroxyl radicals, the sterilizing effect is effectively improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a food cleaning and disinfection device. Background technique [0002] With the continuous development of society, human beings have increasingly urgent requirements for hygiene, environment and health. However, the current planting of fruits and vegetables basically uses chemical fertilizers and pesticides to spray on the plants, so that after the fruits and vegetables are ripe, there may still be some toxic organic residues on the surface. If these residues cannot be effectively removed before eating, the edible Afterwards, it will gradually form a chronic accumulation in the human body, which will cause harm to the human body for a long time. All kinds of meat will have a lot of Salmonella bacteria, washing with water will cause the bacteria to splash around, and contamination of the tableware may cause disease. The traditional disinfection method is to use di...

However, the current planting of fruits and vegetables basically uses chemical fertilizers and pesticides to spray on the plants, so that after the fruits and vegetables are ripe, there may still be some toxic organic residues on the surface. If these residues cannot be effectively removed before eating, the edible Afterwards, it will gradually form a chronic accumulation in the human body, which will cause harm to the human body for a long time

All kinds of meat will have a lot of Salmonella bacteria, washing with water will cause the bacteria to splash around, contaminating the tableware may cause disease

The traditional disinfection method is to use disinfectant, bleach or electrolysis of tap water to produce chlorine gas dissolved in water to produce hypochlorous acid, etc., but this disinfection method will also produce halogenated substances during disinfection, causing secondary pollution; ozone is also available on the market Disinfected fruit and vegetable machine, but using a simple blasting stone or jet, ozone is difficult to dissolve in water, the concentration of ozone in the water cannot meet the disinfection requirements, and it will cause a large amount of ozone to volatilize into the air, causing air pollution
