Fluidized bed dryer layout principle and cleaning method


      The fluidized bed dryer has the advantages of high speed, high efficiency, low process, etc. It can maintain its color and fragrance for heat sensitive materials, and the powder has good solubility and high purity, which is very popular among consumers. Today, I would like to introduce the layout principle and cleaning method of the fluidized bed dryer. I hope to help everyone.

  Fluidized bed dryer layout principle

  1. Straight flow. The main principle of the arrangement is to keep the products or parts flowing in a straight line during the processing. The flow path is as short as possible, and the reverse flow should be avoided as much as possible to shorten the transportation time.

  2. Proper spacing. There must be a certain distance between equipment and equipment, fluidized bed and building, which makes the operation convenient and production safe, while making full use of the workshop area.

  3. When arranging the fluidized bed dryer, it should first be determined whether the arrangement of the fluidized bed is arranged according to the type of equipment or according to the flow operation; whether it is arranged in back-to-back or horizontal or vertical, and then in various arrangements. Select the minimum headroom size between devices from the relevant data. The minimum distance between the equipment and the wall column is also specified and can be found from the relevant information.

  Cleaning method of fluidized bed dryer

  At present, there are three cleaning methods for fluidized bed dryers, namely dry cleaning, wet washing and chemical washing. Among them, dry cleaning mainly refers to cleaning with a brush, a broom, a vacuum cleaner, etc.; the chemical washing method can be divided into lye, acid, and various detergents. Wet washing refers to the cleaning of the centrifugal nozzle of a fluidized bed dryer using hot water with a temperature in the range of 60 to 80 degrees Celsius. The hot water in this range can ensure that the nozzle is cleaned and disinfected more thoroughly.

  In addition to the wet washing method, there are also methods of washing with a chemical agent such as alkali washing and pickling. Among them, alkali washing means that sodium hydroxide is formulated into a solution of 0.5-1% concentration, and then heated to 60 to 80 degrees Celsius, and then washed, and then rinsed with water after washing. In the case of pickling, it is meant that (HNO3) is formulated into a solution at a concentration of 1-2% and heated.

  When the staff is cleaning the fluidized bed dryer, special attention should be paid to the protection of the fluidized bed dryer, and chlorine and its compounds should not be used for washing to avoid oxidation. At the same time, attention should be paid to standard operation, proper use of equipment, and regular maintenance and cleaning of the equipment to extend the life of the equipment.

  The above is about the introduction of the fluidized bed dryer layout principle and cleaning method. I hope everyone can understand the layout principle and cleaning method of the fluidized bed dryer, which will help everyone.
