Laboratory spray dryer is an important laboratory equipment, which is widely used in chemistry, biology, medicine and other fields. Its function is to quickly dry liquid samples such as solutions and suspensions to obtain solid powders or granules. This article will introduce the characteristics, working principle, operation process and precautions of the special spray dryer for the laboratory.
1. Features. 1.Efficient and fast: The special spray dryer for the laboratory can dry liquid samples into solid powders or granules in a short time, which is especially suitable for experiments that require rapid drying of samples.
2.Easy to operate: The equipment has a simple structure and easy to operate, and only a small amount of manual operation is required to complete the experiment.
3.High purity: Due to the high-temperature drying method, the water and organic solvents in the sample can be effectively removed, and the purity of the sample can be improved.
4.High reproducibility: Spray dryers for laboratories are highly reproducible and provide consistent results.
Second, the working principle.
The working principle of the special spray dryer for laboratories is to atomize a liquid sample into fine droplets through a nozzle, and then quickly evaporate the water in a high-temperature drying chamber to obtain a solid powder or particles. The core components are the nozzle and the drying chamber. The role of the nozzle is to atomize the liquid sample into tiny droplets, while the drying chamber provides a high-temperature environment to promote water evaporation.
3. Operational procedures.
1.Preparation stage: First of all, you need to check whether the equipment is normal, and then pour the liquid sample into the feed hopper after confirming that it is correct.
2.Experimental stage: Start the device and set the experimental parameters, such as temperature, wind speed, etc., through the control panel. Then press the start button, the device starts running, and the liquid sample is atomized through the nozzle and enters the high-temperature drying chamber for drying.
3.End phase: When the experiment is over, the device will automatically stop running. At this point, the resulting solid powder or granules need to be removed from the discharge hopper and processed in the next step.
4. Precautions.
1.The equipment should be placed on a well-ventilated laboratory bench to ensure that there is no obstruction around the equipment, so as not to affect the ventilation effect.
2.During the operation, it is necessary to avoid the liquid sample entering the nozzle and the inside of the drying chamber, so as not to affect the normal operation of the equipment.
3.During the experiment, it is necessary to pay close attention to the operation status of the equipment and whether the experimental parameter setting is reasonable, and stop the experiment and check the equipment immediately if there is any abnormality.
4.At the end of the experiment, the obtained solid powder or granules should be removed and stored in time to avoid moisture or contamination.
5.When the equipment is not used for a long time, the functions of the equipment should be checked regularly to see if they are normal, and maintenance and maintenance should be carried out in time.
1. Scope of application
Shanghai Gimei Electronic Technology Co., Ltd. *** ZM-3000TIt is mainly suitable for the laboratory to directly convert liquid materials into tiny powders and ensure the activity of materials. There is no need to filter, concentrate and crush the material before drying, and it has broad-spectrum applicability to all solutions such as emulsion and suspension, which is mainly suitable for universities, research institutes and laboratories of food, pharmaceutical and chemical enterprises.
