Supermarket vegetable spray preservation device, because the temperature and terrain in many areas of our country are different, so much cheaper vegetables are suitable for car transportation to other provinces, so spray humidification equipment is beneficial to supermarket vegetable preservation. The following is the function of vegetable spray preservation device in supermarket.

Supermarket vegetable spray preservation device 1 spray preservation system sprays in a fine physical and chemical state to absorb a lot of heat in the air, and the water mist absorbs the heat in the air and vaporizes to achieve the purpose of * * preservation, cooling and humidification, and the sprayed water mist belongs to nanometer level.

First of all, it can prolong the life of fruits and vegetables, ensure the color of fruits and vegetables and improve the visual effect.

Second, it can ensure the taste of fruits and vegetables, prevent yellowing and prolong freshness.

Third, it can avoid the loss of water and weight of fruits and vegetables and increase the shelf life of fruits and vegetables.

Fourth, it can attract customers' desire to buy, improve the popularity of the supermarket and increase the sales profit of the supermarket.

Application of spray fresh-keeping nozzle:

We have understood the advantages and disadvantages of using atomizing nozzles for spraying in supermarkets. Let's introduce the industry fields where moisturizing nozzles can be used.

Not only can the atomizing nozzle of supermarket humidification system be used in supermarkets, but this nozzle actually belongs to a kind of fine atomizing nozzle. The common vegetable fresh-keeping fine atomizing nozzle in supermarkets is also a common one, which actually belongs to a kind of fine atomizing nozzle. It is not only widely used in the fresh-keeping industry, but also in many processing plants in industrial areas. In some garment manufacturing factories, if there is a lot of dust, atomizing nozzles will be used to reduce dust.

The vegetable spray fresh-keeping device 2 in supermarket looks particularly watery after spraying, which can better cater to customers' psychology. The freshness of fruits and vegetables will enhance the overall goodwill of customers to the store's handling of these products. Therefore, it gives customers a better image and value of shopping center, and the use of spraying system can reduce at least 50% of the waste of selling or discarding fruits and vegetables at reduced prices.

Over time, it is a considerable amount. In addition, it can also avoid the loss of water and weight of fruits and vegetables, and spray it on fruits and vegetables, especially when pricing by quantity, to avoid the volatilization of profits. Ordinary fruits and vegetables usually lose 2%-7% weight within 24 hours. When the weight of fruits and vegetables is reduced, it will also affect the appearance and quality. Weight is usually easier to quantify than appearance and quality. It can be seen that the use of spray humidification equipment can be said to be multifaceted.

Function of vegetable fresh-keeping humidifier in supermarket;

1, prolong the life of fruits and vegetables, keep the fresh and tender color of fruits and vegetables, and improve the visual effect of fruits and vegetables;

2. Keep the original flavor of fruits and vegetables, prevent them from wilting and turning yellow, and prolong the freshness of vegetables;

3. Avoid the loss of moisture and weight of fruits and vegetables, and increase the fresh-keeping period of fruits and vegetables;

4. Attract customers' desire to buy, improve the popularity of buying and increase the sales profit of merchants;

Supermarket humidifier installation:

The installation of spray humidification equipment is also very simple, and it is generally used in conjunction with supermarket shelves. If it is a single-story counter, the machine is generally installed under the counter to save space. This requires the counter to have a certain height to place the vegetable humidifier. General tap water model needs more than 40 cm of space. If it can't be put under the counter, you can put the machine on the side of the counter. Generally, models with bottled water supply are like this.

If it is a multi-layer display stand, and the multi-layer display stand is stepped, it is generally only necessary to install a spray pipe on the upper layer, so that the humidity around the counter will increase, and there is no need to worry about whether each leaf is sprayed with fog. If each floor is separated, it is necessary to install spray pipes on each floor, which requires an increase in spray volume.

Spray fresh-keeping device for supermarket vegetables 3. Performance characteristics of supermarket fruit and vegetable fresh-keeping atomizer;

1, ultrasonic series vegetable fresh-keeping and humidifying machine in supermarket adopts fully sealed design and seals integrated circuit, which ensures that the product is in contact with water for a long time and works safely and reliably without any potential safety hazard.

2. Vegetable fresh-keeping humidifier adopts imported advanced core components to ensure the stability and reliability of the internal quality of the machine.

3. The main engine is made of all stainless steel, which is durable, without aging and corrosion in various environments, with long service life and low comprehensive cost.

4. The invention has the advantages of stable and reliable operation, sensitive control and energy saving, and can fully adapt to various humidity requirements.

5. Different types of machines can not only humidify a large space evenly, but also compensate the local humidity of a special space, so the use flexibility is high.

6. The installation is simple, the humidification can be realized by turning on the water source, the failure rate is low, the later maintenance is time-saving and labor-saving, and there is no pollution to the humidification space during operation.

7. Automatic humidity control of vegetable fresh-keeping humidifier, that is, setting the required space humidity value. When the machine reaches the set humidity value after working for a period of time, the machine will automatically stop. When the humidity in the space decreases, the machine will automatically start working, or it can be set to manual control.

8. The vegetable fresh-keeping humidifier is easy to use and can be placed on the table or mounted on the wall. There is no need for personnel to be on duty during operation, which saves time, effort and worry.

Physically speaking, this method increases the partial pressure of water vapor in the surrounding air, and the evaporation of water has a dynamic equilibrium process, so increasing the partial pressure of water vapor in the air can really slow down the evaporation of water.

More extreme, in a closed system, when the partial pressure of water vapor in the air reaches the saturated partial pressure at the current temperature, the evaporation and condensation rates on the microscopic water surface are the same, so it shows that the evaporation on the macroscopic water surface has stopped.

If the dehydration and drying process of fresh food is regarded as a process of drying clothes in rainy season, then spraying can really delay the dehydration of fresh food.

However, spraying only delayed the dehydration of fresh food. After all, it is impossible for supermarkets to establish a strict closed system, but the preservation of fresh food is not simply moisturizing. Otherwise, it would be easier to just soak in water. After all, fresh food, as an organic matter, has its own problems of corruption and deterioration, so spraying is only effective in moisturizing and cannot solve all problems. .

Why do cities use vegetable rack humidifiers?

In order to ensure the freshness of vegetables and reduce the loss of supermarkets, Dexing, Zhengzhou has developed an ultrasonic spray vegetable fresh-keeping humidifier, which can produce extremely fine water mist floating above vegetables, directly increase the humidity of the air contacted by vegetables, leave no water droplets on vegetables, and keep vegetables as fresh as possible. At the same time, the landscape surrounded by water mist can stimulate consumers' desire to buy, realize sales growth and reduce losses at the same time.

The principle of spray preservation is to slow down the water loss of commodities by forcibly providing local air humidity, which is an indirect preservation method. However, when other methods have shortcomings, this humidification spray preservation method has several advantages, such as low entry cost, low operation and maintenance cost, good effect and convenient implementation. More importantly, this fresh-keeping method adopts water mist fresh-keeping method, which is healthier and can make consumers feel more at ease.
