Membrane dryers have been widely used in industrial production. They not only improve production efficiency and reduce energy consumption, but also achieve environmentally friendly protection, making them an ideal drying equipment. Due to its high drying efficiency, it can greatly shorten the drying time. At the same time, it adopts advanced membrane separation technology, reducing energy consumption and making operating costs relatively low; Reducing exhaust emissions during the drying process makes it more environmentally friendly and meets the requirements of modern industry for environmental protection.

Its structure is simple, easy to operate, and there is no mechanical component movement, avoiding problems such as adhesion and lubricant contamination, and low maintenance costs; During membrane surface heat transfer, pollutants on the surface of solid products can be quickly removed, which not only reduces the damage rate of solid products, but also reduces operating costs; It can be customized according to different application scenarios and requirements, suitable for production and experimental environments of various scales.

Measurement steps for membrane dryer:

1. Sample preparation

-Crushing and mixing: If the sample is in the form of solid blocks or large particles, it needs to be crushed into smaller particles first to ensure that the sample can be fully exposed to a dry environment, improving drying efficiency and uniformity. For uneven samples, sufficient mixing should also be carried out to make each part representative.

-Weighing record: Accurately weigh a certain mass of sample and record the initial weight, which will be used for subsequent calculation of water loss or other related parameters after drying.

2. Install into the dryer

-Uniform placement: Place the prepared sample evenly in a specific position of the membrane dryer to avoid excessive accumulation or uneven distribution of samples, which may affect the drying effect and measurement accuracy. Be careful not to exceed the carrying capacity of the dryer.

-Good sealing: Ensure good sealing performance of the dryer to prevent external air from entering and interfering with the drying process. Check if all interfaces, valves, and other parts are tightly closed, and if necessary, perform a sealing test.

3. Set parameters

-Temperature setting: Reasonably set the drying temperature based on the properties of the sample and drying requirements. Generally speaking, for materials with high thermal sensitivity, lower temperatures should be chosen; For materials with high moisture content and difficult drying, it may be necessary to increase the temperature appropriately, but it is important to avoid excessive temperature that may cause sample deterioration or damage.

-Humidity control: Some membrane dryers have humidity regulation function, which can set the appropriate humidity level according to needs. Maintaining a constant low humidity environment during the drying process helps to accelerate the rate of water evaporation and improve drying efficiency.

-Time preset: Estimate the required drying time and make a preset. In practical operation, appropriate adjustments can be made based on the actual drying condition of the sample. You can conduct a small-scale experiment first to determine the approximate drying time range, and then proceed with the formal measurement.

4. Start drying

-Turn on the device: Start the membrane dryer according to the operating procedures to start running. Observe the operation status of the equipment, including whether the fan is running normally, whether the heating system is working, etc., to ensure the normal operation of the equipment.

-Monitoring process: During the drying process, regularly monitor the status changes of the sample, such as color, shape, weight, etc. The dryness level inside the sample can be checked by sampling, or various parameters during the drying process can be monitored in real-time using sensors and other devices, such as temperature, humidity, weight changes, etc.

5. End drying and data processing

-Stop the equipment: When the predetermined drying time is reached or the sample reaches a constant weight state, stop the operation of the dryer. After the equipment has cooled down to a safe temperature, carefully remove the sample.

-Re weighing: Accurately weigh the dried sample and record the weight. Calculate the water loss, moisture content, and other indicators of the sample based on the initial weight and weight difference. If more detailed analysis is required, other physical and chemical properties of the dried sample can also be tested.
