Is the insulated vegetable cover really insulated? Is the insulated vegetable cover really insulated?

1, the heat-insulating vegetable cover can keep warm. Generally, regular vegetable covers are basically composed of three layers. The innermost layer is aluminum foil, which can reflect light and resist heat. The middle layer is a pearl cotton sandwich, and the surface layer is also plated with a layer of aluminum foil. Therefore, the three-layer insulation can control the air convection and heat transfer inside and outside the vegetable cover, so that the air outside is lower and the heat inside cannot be dissipated, thus achieving the effect of insulation.

2. Therefore, every time we cook in winter, as long as we put the food on the table and cover it with an insulated vegetable cover, the heat in the food will be locked in the vegetable cover soon. According to the survey, even if the food is placed in a heat shield for 30 minutes, the temperature will only drop by 5-8 degrees.
