Foam manufacturers introduce the performance of foam boxes during transportation
Nowadays, foam boxes are increasingly used in our lives, many of which are used to transport vegetables and fruits. But do you know their transportation characteristics? Let's do a test to check it out.
1. When fruits are arranged in a square grid, the temperature distribution is more uniform. When arranged with intervals, the overall rapid cooling is slower, and there is a temperature field inside the fruit. The temperature difference between the surface and the inside is as high as 7℃. The rectangular opening promotes the horizontal spread of cold air. The distance between reference points is increased by about 10 compared to the circular opening, the rapid cooling uniformity is improved by about 10%, and the temperature is reduced by 2°C.
2. During rapid cooling, it is recommended that the hole design and the internal fruit arrangement should match. The well-shaped hole design is more suitable for separate interval arrangement. The simulation and verification of the gas pressure and rapid cooling temperature gradient of fresh fruits in the foam box have been established. The detailed turbulent model of the potential flow part cannot be reproduced after averaging, and the results simulate the rapid cooling flow region of vegetables and fruits.
3. Activities continuously consume nutrients in the body. The inspection shows that vegetable and fruit bags are widely used in the commodity protection of vegetable and fruit circulation, and the shelf life is reduced due to refrigeration during production and acquisition.
4. The layered rapid cooling packaging with poor market sales can improve the efficiency of cold chain logistics and alleviate the pressure. Rapid cooling is an economical, simple, and low-cost forced ventilation rapid cooling method. This post further considers respiratory heat and evaporation heat, using the suction force of the fan to generate pressure on both sides of the foam box, making the three-dimensional rapid cooling shaping force of spherical fruits weak with the buffer layer of the mold in the foam box, thereby driving the cold air to flow through the foam box, and the ventilation holes in the whole body flow through the cargo type, and the lips quickly take away the internal heat, and the temperature drops.
Foam Manufacturers: What characteristics should foam fresh-keeping boxes have?
What characteristics should foam fresh-keeping boxes have to meet the application requirements of a large number of customers? Although many people are very familiar with foam fresh-keeping boxes, such as load-bearing capacity and service life, today we will give you a detailed explanation.
For example, the relative density of this foam fresh-keeping box product is very high. Compared with the original polymer, the relative density of microporous polymer is smaller, so the products produced can achieve better insulation effect, especially in terms of thickness. To a certain extent, they can ensure that the temperature inside the packaging is isolated from the outside for a longer time. Coupled with the use of refrigerated trucks, storing some seafood and other perishable goods is also no problem. Moreover, this product also has good tensile strength, and the tensile strength of the polymer is far less than that of the foamed polymer, and their density is matched. During use, it is not easy to crack due to pulling, and it can also achieve a certain service life, and it can be used repeatedly without any problem.
