Medicinal freeze-drying machine

Medicinal freeze-drying machineFreeze drying technology (abbreviated as freeze-drying) is a new processing technology that has the advantages of low-temperature drying, minimal damage to active ingredients, looseness, easy solubility and absorption, and simultaneous drying and sterilization. Compared with ordinary drying techniques, it dries at low temperatures, resulting in minimal loss of volatile components in the material and better preservation of its original properties, allowing the dried product to be stored for a long time without deterioration.

In recent years, with the rapid development of the pharmaceutical industry,Medicinal freeze-drying machineThe demand is also constantly expanding. The industry points out that the demand for larger equipment in vacuum freeze-drying equipment, as well as equipment with functional combinations such as granulation drying and drying filtration, is constantly increasing. Faced with new market demands and requirements, domestic freeze-drying machine enterprises are also accelerating research on vacuum drying technology, creating more new types of refrigeration equipment to meet users' requirements for reducing energy consumption, pollution, and enterprise costs, bringing more benefits and value to society.

It is worth noting that although refrigeration technology continues to make progress, in order to ensure stable operation and extend the service life of the equipment, users still need to pay attention to the operation, maintenance, and upkeep of the refrigeration equipment during the operation process.

For example, before using refrigeration equipment, users need to understand the precautions during equipment production, including ensuring that the freeze-drying machine operates in a stable environment and avoiding the equipment from being in a dangerous or unbalanced environment; Strictly follow the steps to operate the freeze-drying machine; Avoid contact with corrosive substances to prevent damage to the mechanical properties of the freeze-drying mechanism, which could lead to machine failure; In addition, operators also need to pay attention to preventing limb frostbite and take corresponding protective measures during operation to ensure safe production.

Maintenance is also a key task to ensure the long-term stable operation of freeze-drying equipment. For example, for maintenance and upkeep during equipment operation, it is necessary to check for leaks in water, oil, and gas; Is the cooling effect of the cooling tower good; Before each shift, the washable parts of the machine should be wiped clean; Regularly record the intake, exhaust, and pressure of each level, and fill in the recording requirements according to the content of the record sheet. At the same time, check the intake temperature of the refrigerated dryer; Check whether the automatic and manual discharge are normal, and whether the refrigerated dryer is running normally. If any blockage is found, it needs to be dismantled and cleaned in a timely manner; Check if the water pressure and flow rate of the cooling water system are sufficient; Clean the condenser monthly.

In addition, vulnerable parts should be replaced according to their service life: under normal circumstances, the replacement principle is: the service life of each level of filter (3 microns, 1 micron, 0.01 microns) is 6000 hours for imported filters and 4000 hours for domestic filters. It is worth noting that if the equipment is shut down for a long time, attention should be paid to sewage and all water should be drained. And personnel need to be arranged to keep maintenance records, including time, personnel, maintenance or fault content, replacement parts list and other elements.

At the same time, it is necessary for operators to understand the common causes and solutions of equipment failures, in order to avoid situations where they are helpless when equipment malfunctions. For example, vacuum freeze dryers often experience low vacuum levels, which may be due to high pump temperatures, problems with pump oil, pump leaks, clogged air inlet filters, etc. Solutions include repairing and reassembling; come on. Change the oil; Check the oil inlet volume of the oil circuit and oil valve; Replace the sealing ring or valve plate according to the specific situation; Remove for cleaning, etc.
