Each type of drying oven equipment has a specific range of application, and each drying material can find a variety of drying box devices that can meet the basic requirements of Zui, but there is only one suitable for Zui. If improperly selected, the drying box is not normal. Running. The ideal selection of the drying oven must be selected according to the user's needs. Here are the principles for using dry: 1. The drying device must first be applicable to specific materials and meet the basic requirements for material drying, including good handling of materials (feed, transport, fluidization, dispersion, heat transfer, discharge, etc.) Meet the basic requirements of handling volume, dewatering amount, product quality and so on. 2. The drying rate is high. When the convection is dry, the material is highly dispersed in hot air, the water content is low, the drying speed is fast, and the same convection drying, the drying method has different critical moisture content, and the drying rate is also different. 3. The energy consumption index of the drying box method is different. Generally, the thermal efficiency of conductive drying can reach 100% theoretically, and the convection drying can only be about 70%. 4, the same function of the drying device, sometimes the cost difference is very different, should choose the lower one. 5, low operating costs, dry box and other operating costs should be as low as possible. 6. The drying device with simple structure, sufficient spare parts supply, high reliability and long service life is preferred. 7, in line with environmental requirements, good working conditions, high security. 8. Before the selection, Zui can make the drying experiment of the material, and deeply understand the drying device (extension and disadvantage) that has been used in similar materials, which is very helpful for the selection of the drying box.
Cosmetics are a mixture of various raw materials processed by reasonable allocation. There are many kinds of cosmetics with different properties. According to the cosmetic raw material performance and use, can be divided into two categories of substrate raw materials and auxiliary raw materials. The former is a kind of main raw material of cosmetics, which occupies a large proportion in cosmetics formula and plays a major role in cosmetics. The latter play a role in shaping, stabilizing, or imbuing cosmetics with color, fragrance and other properties that are extremely important in small amounts in cosmetic formulations. Cosmetics is with natural, synthetic or extract all sorts of action different material as raw material, via heating, agitation and emulsification wait for production program processing and become chemical mixture material.
