Spin flash dryer drying process

Spin flash dryer drying process The heat exchange of the dryer is mainly based on the air flow and the particles, and the two heat exchanges between the cylinder wall and the particles. The drying process is essentially the diffusion process of water, which depends on the process that the water in the material becomes steam and diffuses outward. The rotary flash dryer adopts high-speed hot air flow into the cylinder in the tangential direction. Due to the spiral motion of the airflow in the cylinder, on the one hand, the temperature of the medium around the particles is reduced, and the flow rate and temperature of the medium are increased at the same time, which greatly improves the speed of external diffusion. On the other hand, the high-temperature airflow impacts the particles or wet materials in the lower part of the cylinder at high speed, and at the same time, the stirring effect of the stirring blades in the cylinder makes the particles broken, the particle size is reduced, and the diffusion resistance of water is reduced. Most of these particles are repeatedly broken in the cycle of high temperature and high stirring intensity at the lower part of the cylinder, which eliminates the agglomeration of materials, and also promotes the diffusion of water in the powerful measures, which strengthens the evaporation of water. The flow mode of particles and hot air flow: there are both convection and co-current in the lower part of the cylinder, and for coarse particles, it is convection and co-current repeated heat exchange. For fine-grained materials, it is paralleled with the hot air flow, so the drying process can be completed in an instant. For the drying of particles, hot air drying with high temperature and low humidity is actually used. These particles are mainly adsorbed by water molecules and filled between the voids of the particles. Under the conditions of high temperature and low humidity, the heat conduction

Disc Dryer Maintenance Precautions for use

Disc Dryer Maintenance Precautions for use Disc Dryer Maintenance 1. After the operation of the machine is over, please turn the knob of the temperature regulator to the position of 0 degrees to reduce improper startup and prolong the life of the solenoid valve; 2. The setting of the drying temperature should be set correctly according to the drying conditions of the clothes themselves, so as to avoid the shrinkage of the clothes. 3. The batt filter (lower box door) must be cleaned before use every day. If the filter is blocked, the air volume will be reduced, which will cause slow drying, dry drying, and waste of energy. 4. Regularly remove the cotton residue on the temperature sensing rod. When it is found that the temperature difference between the temperature regulator and the thermometer is too large, generally about +5 degrees, it may be that the temperature sensing rod is not placed properly or there is cotton wool on the temperature sensing rod; 5. The time setting of the "cold" timer is usually about 1/4 of the time of the "hot" timer; 6. It is necessary to add butter to the bearing seat every month to ensure the lubricity of the bearing; 7. The exhaust pipes and elbows must be cleaned once a month. If they are not cleaned, the drying time will be prolonged, and too much lint will be blocked, which may easily cause fire. Precautions for the use of disc dryers 1. It is strictly forbidden to directly add bulk and paste materials into the dryer; 2. The feeding device should have good performance to keep the feeding uniform and continuous; 3.

Analysis of common failure causes of linear vibrating fluidized bed dryer

There may be some common small faults during the use of the linear vibrating fluidized bed dryer. Generally, how do we find the reasons for these small faults? We can find out through the fault analysis corresponding to the common faults. Causes to find practical solutions. Fault 1: The temperature display is different from the set temperature. There are several reasons for this, mainly including insufficient steam pressure, failure of steam sensor, failure of electric heating heating, failure of temperature sensor, and too large damper of exhaust air duct. Fault 2: The fuselage moves laterally. There may be two reasons for this: the eccentric block of the vibration motor is not synchronized, and the air volume at the feed end is too large. Fault 3: The discharge speed is too fast. The cause may be that the feed end component is too large, or the included angle of the eccentric block of the vibration motor is too small. Fault 4: The discharge speed is too slow. The cause may be that the weight of the discharge end is too large, and the included angle of the eccentric block of the vibration motor is too large. Fault 5: There are large particles at the discharge port of the cyclone dust collector. The cause may be that the air intake is too large and the air volume of the induced draft fan is too large. Among these failures of the linear vibrating fluidized bed dryer, the corresponding causes can be checked to see if they are serious, and the problems should be found and solved in time, so as not to cause major failures.

How to buy a tunnel type hot air circulation oven

Ovens are necessary equipment in the processing of many products, and tunnel hot air circulation ovens are very popular among ovens due to their excellent characteristics. A suitable tunnel hot air circulation oven helps to save costs, reduce energy consumption, and produce high-quality products, and the correct evaluation of oven technology and cost is of great significance for choosing the appropriate oven technology. So how to choose a suitable tunnel hot air circulation oven? 1. The size of the oven: The size of the oven generally depends on the quantity and size of the materials in the oven. During the constant temperature drying process, the quantity and arrangement of materials in the oven affect the temperature uniformity of the drying chamber. When the temperature uniformity is high, it is recommended to reduce the number of samples or choose a large oven to ensure hot air convection in the drying chamber. 2. Temperature range and operating temperature: Different types of ovens have different adjustable oven temperatures. When choosing, it is necessary to ensure that the operating temperature is lower than the maximum temperature to prevent the body from being overloaded and damaged. 3. Temperature uniformity: The temperature uniformity of the tunnel-type hot air circulation oven is an important performance index, which refers to the temperature difference at each point in the drying room during the constant temperature stage of the oven. A large temperature difference will result in uneven heating of the sample at different locations. 4. Heating power: The normal heating rate of the hot blast stove is generally 10/min. When heating at low temperature, the temperature rises quickly, the temperature rises slowly at high temperature, the temperature rises rapidly in summer, and the temperature rises slowly in winter. Increasing the heating power can increase the heating speed. But the heating power o
