Product Description:

Product introduction: including hot air blower (smoke heat), moisture exhaust fan (smoke heat), tunnel kiln smoke exhaust fan, kiln tail cooling fan, under-vehicle cooling fan, air supply fan (waste heat), and moisture exhaust fan (waste heat).

Note: It can be customized according to specific projects.

The fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. Fan is the habitual abbreviation for gas compression and gas conveying machinery in China. Fans include ventilators, blowers, and wind generators.

Fans are widely used in ventilation, dust removal and cooling in factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and induced draft in boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances; Drying and selection of grain, air source of wind tunnel and inflation and propulsion of hovercraft, etc.

Q:What are the types of drying equipment?
According to the operating pressure, the dryer is divided into two types of atmospheric pressure dryer and vacuum dryer. Microwave flour sterilization drying equipment can reduce the moisture partial pressure of the space and accelerate the drying process, and can reduce the wet boiling point and material Drying temperature, steam is not easy to leak, so the vacuum dryer for dry heat-sensitive, easy oxidation, explosive and toxic materials and wet steam needs to be recycled occasions.
Q:The working principle of belt dryer
Drying process is a hot air flow through the material layer, complete the process of heat and mass transfer, the upper cavity connected by the duct and the fan inlet. Most of the gas circulation, part of the lower temperature of the larger moisture content of the gas as exhaust gas through the drainage tube, regulating valve, drain fan discharge. The next cycle of the unit, the fan out of the wind into the upper cavity, down through the heat exchanger heating, through the material layer into the lower chamber, the lower chamber by the side duct and return air duct connected to the fan, most of the gas circulation, Part of the discharge. Up and down the cycle unit according to user needs can be flexible equipment, the number of units can also be selected according to need.
Q:What is a combination of drying equipment?
Recently, a combination of different drying methods and different drying principles has been widely used, and a drying device capable of exerting their own advantages and making up their respective shortcomings.
Q:Frozen sublimation drying equipment which consists of several systems
the heating system: for heating the freeze-drying room shelf, to promote the material within the ice sublimation, direct and indirect heating in two ways, direct heating is the direct heating in the box inside the shelf, indirect heating is the use of electricity Or other heat source heat transfer medium, and then pass it into the shelf.
Q:The development prospects of the dryer
Compared with the adsorption dryer, the cold and dry machine is relatively energy efficient in its applicable field. But the cold and dry machine in the small load operation also exists "big horse car" energy waste phenomenon. People want the cold and dry power consumption can follow the load changes and adjust themselves to achieve the best energy saving effect,
Q:What is the best drying equipment?
In the traditional horizontal fan-type dryer, the air flow only in the material surface flow, the drawback is the low heat transfer coefficient, poor heat utilization, material drying time is long.
Q:How to choose the right drying equipment and drying technology
Materials can be divided into two kinds of hygroscopic and non-hygroscopic.
Q:What are the basic types of common drying equipment?
(2) Belt Dryer Belt Dryer consists of several independent unit segments. Each unit section includes a circulating fan, a heating device, a separate or common fresh air extraction system and an exhaust gas extraction system. On the drying medium quantity, temperature, humidity and exhaust gas circulation operating parameters, can be independently controlled, so as to ensure the reliability of working with dry and operating conditions optimization.
Q:What are the common drying methods?
Mechanical dehydration method is through the way of the material pressure, will be part of the water extrusion. Commonly used in pressing, sedimentation, filtration, centrifugal separation and other methods. Mechanical dehydration method can only remove part of the material free water, combined with water remains Material, so the material after the mechanical dehydration of the material moisture content is still high, generally 40 to 60%, but the mechanical dehydration method is one of the most economical method.
Q:How to solve the dryer a series of failures
On the other hand, after the dryer was replaced, the dew point immediately peaked, indicating that the dryer was not adequately cooled before it was so well that it could not adsorb moisture well and that the dew point of the dryer would be reduced to normal after cooling. If the dryer is cooled properly, it will cause the temperature to peak. The sudden change in temperature will reduce the drying ability of the desiccant to heat-sensitive materials such as ionomers, amorphous polyesters and certain nylon grades.
