Both the once setting tunnel dryer and the roasting kiln carrying equipment are kiln cars. The section of the dryer is the same as roasting kiln.

The structure of the dryer is a brick-concrete. The side walls are composed of red brickwork and reinforced concrete structural columns. The roof is cast-in-place reinforced concrete, and aerated concrete brickworks are used for thermal insulation.

The drying medium is generally provided by the waste heat and flue heat of the roasting kiln. The dryer is equipped with a hot air supply system, a moisture exhaust system and a temperature and humidity monitoring system. By monitoring and adjusting the system, the supply air temperature and air volume can be controlled to ensure the drying quality of the bricks.

Q:What is the best drying equipment?: After the wet air is withdrawn from the inclined duct beneath the baking tray, a portion of the wet air is discharged from the oven through the centrifugal fan.

Q:Frozen sublimation drying equipment which consists of several systems: the vacuum system: by the freeze-drying room, condenser, vacuum valves and pipes, vacuum equipment and vacuum instrument composition, the current vacuum equipment is extremely combination of three: the Roots pump, cryogenic condenser, and multi-stage steam ejector, which , Multi-stage steam ejector structure is simple, no mechanical power, easy maintenance, low failure rate, the material requirements are not high, usually need to set 4-5 level.

Q:How to choose the right drying equipment and drying technology: Materials can be divided into two kinds of hygroscopic and non-hygroscopic.

Q:The working principle of belt dryer: For the material temperature does not exceed 60oC requirements, can be used about 80oC dry gas. Multi-stage combination can better play the performance of belt dryer, and dry more uniform.

Q:What is a combination of drying equipment?: As we all know, each dryer there are some shortcomings, through the same or two or more models in series, using their own advantages, often play a single device can not achieve the purpose.

Q:What are the characteristics of the drum dryer?: According to the dry material is heated, the current rotary drum dryer can be divided into five types, that is, direct Heating dryer, indirect heating dryer, compound heating dryer, steam calcining dryer, spray granulation drying machine.

Q:How to solve the dryer a series of failures: The moisture absorption capacity of the dryer is limited, so the moisture it adsorbs must be removed by regeneration. The process is: when the ambient air is inhaled, through a filter into the blower, and then be sent to a group of heaters. The heated air passes through the machine. When the temperature of the dryer rises, the adsorbed moisture is released. When the hot air to absorb water vapor to saturation, it was discharged into the atmosphere. The high temperature regenerative dryer must be cooled before returning to the dry loop to restore the moisture absorption function of the dryer.

Q:The development prospects of the dryer: performance, the use of compact heat exchangers, such as plate fin heat exchangers, is promising. (The current difficulties may still be in terms of price). Promotion of the use of green ring-type refrigerant R134a, including cold and dry machines, including all the direction of development of refrigeration equipment, technically there is no insurmountable obstacles. But this is a great social engineering, an industry, a separate action of a business in addition to some commercial publicity significance, the overall goal of the macro is not much practical effect. In the final analysis, this is a government action, the need for the introduction of policies by the state to define a unified time limit.

Q:What are the types of drying equipment?: he equipment used for the drying operation. Many types. According to the operating pressure can be divided into atmospheric pressure and pressure (vacuum dryer also known as vacuum dryer). According to the operation method can be divided into intermittent and continuous. According to the drying medium can be divided into air, flue gas or other drying medium. According to the movement (material movement and drying medium flow) can be divided into parallel, countercurrent and cross flow.

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.
