It is crucial to choose a suitable installation site. The site should be kept dry and well ventilated, and avoid direct sunlight and humid environment to prevent the equipment from being damaged by moisture. At the same time, ensure that there is enough space on the site to facilitate the placement of the equipment and subsequent maintenance operations. The ground needs to be flat and able to bear the weight of the equipment. Generally, the ground bearing capacity is required to be no less than the total weight of the equipment during operation. In addition, the distance between the equipment and other surrounding facilities must be considered to facilitate pipeline connection and personnel operation.
When moving the normal temperature refrigerated dryer, it is necessary to strictly follow the requirements of the equipment manual and use appropriate handling tools, such as forklifts, cranes, etc., to avoid collision or severe vibration of the equipment. Place the equipment steadily on the pre-prepared installation position to ensure that the level of the equipment meets the requirements. A level can be used for detection and adjustment. By adjusting the anchor bolts of the equipment, the equipment can be leveled, which is very important for the normal operation of the internal components of the equipment and preventing leakage and other problems.
The normal temperature refrigerated dryer involves the connection of multiple pipes, such as refrigeration pipes, vacuum pipes, drainage pipes, etc. When connecting pipes, first ensure that the pipes are clean to prevent impurities from entering the equipment. The connection of the pipeline should be firm and reliable, and appropriate sealing materials should be used to prevent leakage. For refrigeration pipelines, pay attention to the direction and slope of the pipeline to ensure the normal flow of refrigerant. The connection of the vacuum pipeline should ensure good sealing to meet the vacuum requirements of the equipment. The drainage pipeline should be connected smoothly to ensure that the condensed water generated during the operation of the equipment can be discharged smoothly.
Correct electrical connection is the guarantee of safe operation of the equipment. Before making electrical connections, the power supply must be cut off, and it must be ensured that the operator has relevant electrical knowledge and safety awareness. According to the electrical schematic diagram of the equipment, connect the power cord, control line, etc. to the corresponding interface. When connecting, pay attention to the correctness and firmness of the wiring to avoid problems such as virtual connection or short circuit. After the connection is completed, carefully check whether the line is connected correctly and the grounding is good to prevent electric shock or other electrical failures during the operation of the equipment.
The refrigeration system is one of the core parts of the normal temperature refrigerated dryer. Before debugging the refrigeration system, check whether the oil level of the refrigeration compressor, the amount of refrigerant charged, etc. meet the requirements. Then, start the refrigeration compressor and observe its operating status, including whether the sound, vibration, temperature, etc. of the compressor are normal. At the same time, the pressure and temperature parameters of the refrigeration system should be monitored to ensure that the refrigeration system can operate normally and meet the set low temperature requirements. By adjusting the relevant parameters of the refrigeration system, such as the opening of the expansion valve, the refrigeration system is in the best working state.
The vacuum system is crucial to the freeze-drying process. First, check whether the vacuum pump is installed correctly and whether the lubricating oil is sufficient. After starting the vacuum pump, observe the operation of the vacuum pump and check whether there is leakage in the vacuum pipeline. The vacuum degree of the system can be tested using tools such as a vacuum tester, and the system can be gradually pumped into the set vacuum degree range. During the debugging process, pay attention to whether the vacuum pump's exhaust rate and ultimate vacuum degree meet the requirements of the equipment. If there is a problem, find the cause in time and make adjustments or repairs.
After completing the above debugging, conduct an overall performance test of the normal temperature refrigerated dryer. Put an appropriate amount of material into the drying bin and conduct a freeze-drying test according to the set process parameters. During the test, closely observe the operation of the equipment, including changes in parameters such as temperature, pressure, vacuum degree, and the drying effect of the material. According to the test results, the parameters of the equipment are further adjusted and optimized until the equipment can operate stably and efficiently to achieve the expected drying effect and product quality requirements.
The installation and commissioning of the normal temperature refrigerated dryer needs to be carried out strictly in accordance with the operating procedures. Every link must be taken seriously to ensure that the equipment can operate normally and provide reliable guarantee for subsequent production work.
