[0002] When preparing essence products, different raw materials will be added according to the required ratio. In order to achieve better processing effects and make the products have better performance, the raw materials for preparing essence are usually preheated and pretreated, such as heating the raw materials appropriately to change them from a gel state to a liquid state. When the production output is large, these raw materials need to be placed in a heating device or a constant temperature device to ensure that they remain in a liquid state that can be used at any time. Due to the additional configuration of these heating devices or constant temperature devices and the long working hours, it not only increases the production cost of the enterprise but also is not energy-saving and environmentally friendly.
