Vibrating Fluid Bed Dryer

Vibrating Fluid Bed Dryer Introduction

The Hywell Machinery vibrating fluid bed dryer is a new technology developed on the basis of the static fluidized bed dryer. Mechanical vibration is added to the fluidized bed dryer. The material has been fed into the vibratingfluid bed dryer, under the dual function of the vibrating and airflow, the material move along the fluidized bed as throwing forward continuously. Hot air upward through the fluidized bed and wet materials from the heat after the exchange. And after dried products will be discharged from the vibrating fluid bed dryer. Our company not only has a vibrating fluidized bed dryer, but it also has a fluidized bed granulator.

Shaking Fluid Bed Dryer Description

The shaking fluid bed dryer includes the heating device, main machine, air filtration system for products, and air system.

The main air heating system of the shaking fluid bed dryer supplies the drying chamber with the designed amount of air. The air rate is calculated with Hywell machinery’s process calculation program.

The program of shaking fluid bed dryer is based on the actual ambient conditions at the physical place where the dryer will be installed.

The main air system of the shaking fluid bed dryers consists of air filters, pre-heating systems, an air heater, a supply fan, and from time to time a dehumidification system. The main air system of the shaking fluid bed dryer is constructed according to the actual requirements of the product and the ambient conditions.

Fines and air filtration system of fluid bed dryer process, The fines coming out of the drying chamber and the external fluid bed together with the exhaust air will be separated from the exhaust air before letting it into the atmosphere.

Cyclones and bag filters of the shaking fluid bed dryers are the most common ways of filtrating the fines from the air. Cyclones seldom stand alone. This is because the emission will often violate the environmental requirements in terms of the permitted mg of powder per m3/air. Therefore, a bag filter is necessary(option).

A bag filter of the shaking fluid bed dryer can be a standalone solution as this technology is able to remove the required powder fines before outlet to the atmosphere. The fines are collected in a fines return system, thereby the powder loss is reduced to a minimum. The fines can be re-entered to the top of the drying chamber, to achieve agglomeration of the powder or they can be sent to the internal or external fluid bed. Again, the required powder specifications will decide the design of the fines system.

Powder sifter (option): The final step of the shaking fluid bed dryer is the powder sifter. The powder sifter will separate the large powder particles from the powder, size is determined for the separation. The off size is bagged off and the powder can be either directly packed into big bags or conveyed to a silo system for other packing systems.

if the materials is heat sensitive, it can use our vacuum tray dryer to dry it.

Drying bed plate model of vibration fluid bed dryer

    The vibration fluid bed dryer board is the main place where the material has been in contact with the material during the whole drying process and the water evaporates. so the bedboard of the vibration fluid bed dryer is very important. According to the characteristics of different materials, the fluidized bed dryer has a variety of drying bed plates to choose from.  Hywell machinery has a straight perforated plate, tongue type perforated plate, mesh plate, or mixed perforated plate. For materials with small specific gravity, tongue-shaped hole bed plates are generally used. For powders or particles with large specific gravity and small particles, mesh plates are generally used (the minimum hole can reach 0.2 mm), such as salt, sodium sulfate, etc. Welcome to consult Hywell machinery. our engineers will give you free technical consultation.

Heating method of vibration fluidized bed dryer

The vibration fluidized bed dryer has large output and needs a large amount of air and heat energy. The heating methods of vibration fluidized bed dryers usually used are steam, gas or oil hot blast stove, coal-fired furnace, and electric heater. Of course, electric heating is the last choice, because big heat energy needs big electric heater power. The specific heating method is determined according to the material characteristics and the actual conditions of use. about this detail, please contact Hywell machinery company and we will give free suggestion.

Fluidized Bed Dryer Construction Materials

Hywell Machinery is able to offer our ZLG series fluidized bed dryer with contact parts to be built in SS304, SS316L, Titanium, Duplex stainless steel, etc. Electrical parts of the control system of the drying machine can be adapted to the customer’s needs.

How do the Vibratory Fluid Bed Dryer Works

A continuous fluid bed system is a machine in which a continuous flow of “wet” powder, granular, or flakes material is conveyed over a perforated bed.  Hot drying air is blown through the holes of a perforated plate.  The wet solids are lifted from the bottom and cause the solids to behave as fluid. The air velocity is adjusted to keep the moving layer of material fluidized.
