Comparative analysis of drying equipment for monosodium glutamate cell protein
The drying of monosodium glutamate cell protein is a hot issue in drying technology research. Because of its high viscosity and high humidity, there are many equipment used in engineering practice1 tube bundle dryer
2 high speed stirring dryer
3 rotary flash dryer.
From the quality of drying products, high-speed stirring dryer is better, followed by rotary flash dryer and tube bundle dryer.
From the cost of drying products, the cost of tube bundle dryer is low, followed by high-speed stirring dryer and rotary flash dryer
The heat source of tube bundle dryer is steam, and other dryers use mechanical grate coal-fired hot blast stove or hand-fired hot-air stove.
The system of tube bundle dryer is simple, but the structure is complex, and there are many maintenance points. The structure of high-speed stirring dryer and rotary flash dryer is simple and easy to maintain,.
Although the tube bundle dryer is characterized by high efficiency, it is difficult for the tube bundle dryer to deal with the high viscosity materials due to its high viscosity. Therefore, it is necessary to use the back mixing process to mix a large number of dry materials into the wet materials to reduce the viscosity of the materials. As a result, in the drying of monosodium glutamate thalli protein, the use efficiency of tube bundle drying is relatively low, and the water removal capacity is determined by 4-5kg water / m2. H is reduced to 3-3.5kg water / m2. H.
Therefore, now the general manufacturers in the selection of monosodium glutamate cell protein drying equipment, has rarely used the tube bundle dryer. At present, the tube bundle dryer is mainly used for drying germ, fiber, distiller's grains and other materials.
The rotary flash dryer must be specially designed for monosodium glutamate cell protein, not general purpose. The general rotary flash dryer needs to make corresponding improvement for monosodium glutamate cell protein, otherwise the drying effect is not good.
High speed stirring dryer is a new type of drying equipment developed by ourselves. It is mainly aimed at drying high viscosity and high humidity materials. The first monosodium glutamate thalli protein dryer in China is the high-speed stirring dryer. This kind of equipment can dry products with high quality, simple structure and easy maintenance
