Melon and fruit heat shrink packaging machine - Packing Temperature in supermarket
Heat shrink packaging machine use the different temperature for various vegetables, melons and fruits, which is important.Nowadays, melons and fruits are the hot selling products in the retail industry of large supermarkets. In order to keep the fruits fresh for a long time and ensure that they are not easily damaged during transportation, production companies have begun to use heat shrink packaging machines for fruits and melons in large supermarkets for protection. Many products in life use the heat shrink packaging machine. To put it simply, the product is well wrapped with heat shrinkable film.
Many customers find that they do not know how to use the machine after buying it, the temperature of the melon and fruit heat shrink packaging machine in large supermarkets, and how high should it be adjusted to suit melon and fruit packaging.
The temperature for melon and fruit heat shrink packaging machine in large supermarkets:
What we need to pay attention to when using is that due to the different installation positions of the equipment sensors of each manufacturer, the displayed temperature deviation will also be relatively large. If it can be directly debugged on site, the effect will be excellent.
(1): Depending on the thickness of the material, the speed of conveying the product, the size of the air volume, and the temperature setting, the product will vary.
(2): Different vegetables have different suitable storage temperatures, and those with high temperature resistance can use low temperatures.
In theory, the melon and fruit heat shrink packaging machine of large supermarkets can The power is generally around 20-40KW, and the set temperature is also relatively high, generally around 180°-220°
For example, the optimal storage temperature for most leafy vegetables such as spinach, lettuce, etc. is 0-4°C;
For root vegetables such as carrots and potatoes, the optimal storage temperature is 1-3°C.
Therefore, when packaging vegetables, supermarkets need to adjust the temperature of the machine according to the type of vegetables to ensure the freshness of the vegetables.
(3): Adjust the temperature according to different packing materials:
The shrinkage temperature of PVC is about 130-160 degrees Celsius, and the temperature of PE shrink film is about 140-170 degrees Celsius. The power of POF and PVC shrinking machines is generally 5-20KW, and the temperature is generally set at about 140-160 degrees. The adjustment is basically the same as that of the PE shrink machine.
So for supermarket melon and fruit heat shrink packaging machine, due to the different quality of the shrink film, there will also be a large deviation in the heat shrink temperature.
(4): Depending on the position of the thermoelectric device of different manufacturers, the same shrink film may not shrink well even if the temperature control shows 200°. Some temperature control meters show 100° but the shrinkage effect is already very good.
(5): In addition, supermarkets also need to reasonably arrange the purchase time and quantity of vegetables based on factors such as the characteristics of vegetables and seasonal changes to ensure the freshness of vegetables.
The above content is the specific content of how much the temperature of the melon and fruit heat shrink packaging machine in large supermarkets should be adjusted. We must operate it carefully during the use process, so as to ensure our safety and at the same time improve the heat shrinkage of melon and fruit in large supermarkets. So then the packaging efficiency of the packaging machine reduces the investment cost of the enterprise.
