Description

Technical Field

[0001] The present application relates to the technical field of solid material melting, and more specifically, to a solid material melting and heat preservation machine. Background Art

[0002] For melting solid materials used in the production of polyurethane products, there are two melting methods in the relevant technology, one is to use a baking furnace for heating and melting, and the other is to use an induction cooker for heating and melting. The baking furnace heating uses a heating tube to provide heat and then uses a fan to circulate hot air inside the baking furnace for heating. This method uses a long heating time to heat the solid material to melt the material, resulting in high energy consumption. The material is placed in a container, and the container is placed in the baking furnace at a high heating temperature, which poses a risk of scalding to the person taking the material; induction cooker heating is to put the material in a metal basin, and then place the metal plate on the induction cooker to melt the material through conduction heating. Using this method, when the material is completely melted, the material in direct contact with the metal basin is prone to overheating, causing the material to discolor and affect the quality. The material that is not directly in contact with the metal basin takes a long time to melt when dissipating heat, which easily leads to high energy consumption required to completely melt the material. Therefore, it is necessary to propose a melting and heat preservation equipment that is easy to take materials, has low energy consumption, and is not easy to overheat the material.
