At present, the main equipment used for the drying of domestic monosodium glutamate protein is:
1 Tube dryer 2 High speed mixer dryer 3 Rotary flash dryer.
From the standpoint of dry product quality, high-speed stirring dryers are the best, followed by rotary flash dryers and tube-bundle dryers.
From the standpoint of the cost of the drying equipment, the cost of the tube dryer is the lowest, followed by the high-speed stirring dryer and the rotary flash dryer. The heat source used in the tube-bundle dryer is steam, and other dryers use a mechanical grate coal-fired hot air stove or a hand-fired hot-blast stove.
The tube bundle dryer system has a simple composition, but has a complex structure and many maintenance points. The high-speed mixing dryer and the rotary flash dryer have a simple structure and are easy to maintain and maintain.
Although the tube dryer has high efficiency, because the MSG bacterial protein is a high-viscosity material, the tube-bundle dryer is difficult to handle high-viscosity materials, and only the back-mixing process can be used, and a large amount of dry material is mixed in the wet material to reduce the amount of material. Viscosity, so that in the dryness of the monosodium glutamate protein, the use efficiency of the tube bundle drying is rather low, and the water removal capacity is reduced from 4-5kg water/M2.h to 3-3.5kg water/M2. h. Therefore, nowadays, when manufacturers use MSG protein drying equipment, the tube dryer is rarely used. Tubular dryers are currently mainly used for the drying of germ, fiber, distiller's grains and other materials.
Rotary flash dryer must be specially designed for MSG bacteria protein. It is not general and universal. Rotary flash dryers generally need to be improved for MSG bacteria protein, otherwise the drying effect is not good.
High-speed stirring dryer is a new type of drying equipment developed by us. It is mainly used for the drying of high-viscosity and high-humidity materials. The first Taiwan MSG bacterial protein dryer is a high-speed mixing dryer. This kind of equipment has high-quality drying products. It is simple in structure, easy to maintain and maintain.
