Crystal ice coffin? It is best to put the body in the freezer (portable ice coffin)

I am Guo Jun, general manager of Yong 'an Anti-corrosion Refrigeration Equipment Factory, and also the patent holder of portable ice coffin. It is said that the crystal ice coffin and the remains anti-corrosion freezer (portable ice coffin) have their own advantages. As we are all producing, it seems that the portable ice coffin can be comparable to the crystal ice coffin in refrigeration effect, service life and function. Someone asked us: the crystal ice coffin has two hosts, and the portable ice coffin has only one host. How can it have the effect of a crystal ice coffin? Among them, only one-the lid of the crystal ice coffin is transparent, and when the light enters, there is heat energy in the sunlight. The crystal ice coffin is connected with metal inside and outside, so that the metal can transfer cold energy and evaporate when it meets air. In this way, most of the refrigeration of the crystal ice coffin is wasted. Hand-held ice coffins are generally placed in coffins, paper coffins, body bags boxes, etc. There is no sunshine, so there is no heat. Moreover, coffins, paper coffins and body bags boxes are not made of metal, and they are neither cold nor conductive. Of course, the effect is good. To say that operation, transportation and inventory are of course portable ice coffins, which have small investment and low power consumption. This is the decline in the sales of crystal ice coffins in China, including our crystal ice coffins and the preservation of our portable ice coffins.
