Dryer Su Cheng Drying effect class vegetable protein dryer

Mainly sticky wall is serious is a spray drying chamber adhesion wet powder everywhere. The reason is that the feed amount is too large to fully evaporate; begin before spray drying chamber spray insufficient heating; at the start of spraying, cutting the flow adjustment is too large; material was unstable added. For different reasons, the above problems can be taken in order the following measures: appropriate to reduce the amount of feed; appropriately increasing the temperature of the hot air inlet and outlet; at the start of spraying, flow to small, gradually increase, when adjusted to the appropriate date; check the pipe is blocked, adjust the solids content of materials, to ensure the fluidity of molten material. I. Overview: High speed centrifugal spray drying equipment is a suitable emulsions, suspensions, burnt fingers, solutions and other liquid and dry special drying equipment. Fertilizer class; detergents and surfactants categories:: dried organic compounds, inorganic compounds Branch in polymers and resins: dye, pigment classes: ceramics, glass, rust remover, insecticide classes: carbohydrates, dairy category , the performance was particularly impressive. Second, Features: ◆ fast-drying, generally only 5-15 seconds, with a momentary dry; ◆ material to complete the drying process in a short time, adapted to the heat-sensitive materials can be dried, can keep the material color, high flavor, taste and purity of the finished product, good quality; ◆ production process simplified. Manipulation easy to control, suitable for continuous control of the production: the moisture content of 40% -90% of the liquid, once dried into a powder, reduce the crushing and screening process; ◆ product dispersion, mobility, good solubility, size, bulk density , moisture is adjustable within a certain range. Due to the late start of China's food machinery, it is now a spray with similar foreign equipment for domestic use there is still a gap. Most foreign drying equipment automatic welding technology, weld polished, polished surface of the device has taken or passivation. Experts say, in order to shorten the gap with foreign countries, we have only started to improve from intelligent devices and processing methods, processing quality and other aspects. Future development will be an in-depth study of spray drying mechanism and material drying characteristics, master of different materials under optimum operating conditions, the development and improvement of a spray dryer.
