Brief description of HZG series rotary kiln dryer

At present, rotary kiln dryers are mostly used in chemical, mining, metallurgy, fertilizer and other industries. The material has a large proportion and large particles, and it is suitable for use with a high inlet air temperature. However, the original form of the material is fibrous, light in specific gravity, watery Large portions and high temperature materials (such as turmeric saponin) have always been the key to overcome. For this reason, the company has developed a multi-circuit rotary kiln dryer based on the characteristics of the rotary kiln dryer itself and material characteristics. Working principle: The wet material enters the inner layer of the three-layer drum from the feeding device to realize downstream drying. The material is continuously picked up under the inner layer of the plate, scattered in a spiral way to achieve heat exchange, and the material moves to the other end of the inner layer. Entering into the middle layer for countercurrent drying, the material in the middle layer is continuously raised and advanced repeatedly, in a way of two steps forward and one step back. The drying time is prolonged, and the material reaches the best drying state here. The material travels to the other end of the middle layer and falls into the outer layer. The material travels in a rectangular multi-loop way in the outer drum, and the material that achieves the drying effect travels quickly under the action of hot air. After discharging from the drum, the wet material that has not achieved the drying effect cannot travel quickly due to its own weight. The material is fully dried in this rectangular copy board to achieve the purpose of drying. After the heated hot air enters the kiln and contacts with the material, it conducts heat and mass transfer quickly. After the hot air contacts the wet material, the humidity drops rapidly. After the material absorbs heat, the moisture is quickly evaporated. The fine powder i

Spray Dryer Process

The spray drying process is far older than people's imagination. The earliest description dates back to 1860, and the earliest record of design patents is 1872. The basic principle of spray drying is to produce highly dispersible powder products by evaporating the solvent contained in the liquid feed. It is achieved by mixing the heating gas with a mist (spray) stream with a high surface mass ratio in a container (drying chamber), and direct contact to make the solvent evaporate uniformly and quickly. The size of the mist droplets are preferably the same. Spray drying is widely used in the production of fluid powders. The dehydration method has been successfully applied in the following fields: Pharmaceutical Bone and tooth amalgam Drink Spices, dyes and plant extracts Milk and egg products Plastics, polymers and resins Soap and detergent Textiles and many other products Almost all other drying methods, including the use of ovens, freeze-drying and rotary evaporators, will cause a large amount of materials to be further processed (such as grinding and screening), resulting in uneven particle size and shape. On the contrary, spray drying can more flexibly control the characteristics of powder particles such as density, size, fluid characteristics and humidity. Design and control The challenge faced by designers and users is to increase output, improve the quality of powder products, and reduce costs. This requires a deep understanding of the production process and efficient implementation of production control. Spray drying consists of the following stages: Supply preparation: it can be homogeneous, pumpable, impurity-free liquid, suspended solids, or viscous materials. Atomization (converting the feed into droplets): This is the most critical step of the process. The degree of atomization determines th
