Spray dryer air temperature of the bulk density of the product will have a significant impact occurred. Temperature of hot air has a tendency to produce low bulk density spray ranking, which is due to the effect of hot air rapid drying, hardening the surface of the particles and the residue of moisture expansion, and promoting the formation of a balloon-shaped hollow particles. If the requirements of high bulk density (low hematocrit), or require solid particles, the design should not be used in contact with high temperature hot new droplet formation. In chemicals, drying, hot air temperatures up to 538 ℃, spray use, large product particles. You can find there is enough residual steam pressure of the outer surface of the blown hollow. In the food spray drying, hot air temperature is generally not more than 177 ℃, spray, thus forming the initial diameter of the hollow particles is not as big as chemicals. Changzhou Kai Ruisi Machinery Co., Ltd. The main products are: belt dryer, spray dryer, vibration fluidized bed dryer, a vacuum dryer, paddle dryer, rotary drum dryer, fluid bed dryer, flash dryer , disc dryer, air drying machines. Fire and explosion protection spray dryer system operating strict attention to the following: a. Control the drying temperature and the rotary atomizer loads. b. Control the cleanliness of the dried product. Burning coke or discoloration of the product may be caused by the burning of deposits. c. Discharge amount control products to discover whether there goods remain in the drying chamber. d. Prevent oil leakage from the rotary atomizer people into the drying chamber. e. Note spray-drying apparatus exhaust gas odor. The operator must be familiar with the taste of burning coke gas deposits. Temperature detecting means provided in the spray-drying chamber or pipe wall surface portion prone sediments, temperature detecting means is provided to reduce the fire hazard commonly used method. But this temperature detection system can not prevent fire, nor very reliable. Spray ranking Kai Ruisi machinery (certified), spray supplied by Changzhou 凯瑞思 Machinery Co. Changzhou 凯瑞思 Machinery Co. (www.krsjx.com) is a leader in Changzhou, Jiangsu, drying equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
