Water-filled ice packs are commonly used tools for cold chain transportation, widely applicable for items that require refrigeration during transport such as food, الأدوية, والعينات البيولوجية. The inner bag of the water-filled ice pack is made of high-density material, while the outer layer is made of durable plastic, providing excellent sealing and pressure resistance. By filling with water and freezing, water-filled ice packs can effectively maintain a low-temperature environment for transported items.
– Place the water-filled ice pack on a clean surface and locate the water inlet at the top of the ice pack.
– Use clean tap water or distilled water to carefully fill the ice pack through the inlet. It is recommended to fill the ice pack to 80%-90% capacity to avoid overfilling, which could cause the ice pack to burst when frozen.
– After filling, ensure the sealing strip or cap of the water inlet is fully closed to prevent any leakage.
– Gently squeeze the ice pack to check for any leakage. If there is leakage, readjust the sealing strip or cap until it is completely sealed.
– Place the sealed water-filled ice pack flat in the freezer, set at -20℃ or below.
– Freeze the ice pack for at least 12 hours to ensure the water inside is completely frozen.
– Choose a suitable insulated container, مثل مربع معزول لكبار الشخصيات, EPS مربع معزول, أو مربع EPP المعزول, and ensure that the container is clean both inside and out.
– Check the seal of the insulated container to ensure it can maintain a consistent low-temperature environment during transport.
– Remove the pre-cooled water-filled ice pack from the freezer and quickly place it into the insulated container.
– Depending on the number of items to be refrigerated and the transport duration, arrange the ice packs appropriately. It is generally recommended to distribute the ice packs evenly around the container for comprehensive cooling.
– Place the items that need to be refrigerated, such as food, الأدوية, أو العينات البيولوجية, في الحاوية المعزولة.
– استخدم طبقات الفصل أو مواد الوسائد (مثل الرغوة أو الإسفنج) to keep the items from directly contacting the ice packs to prevent frostbite.
– Close the lid of the insulated container and ensure it is sealed properly. For long-duration transport, use tape or other sealing materials to further reinforce the seal.
– Move the insulated container with the water-filled ice packs and refrigerated items onto the transport vehicle, تجنب التعرض لأشعة الشمس أو درجات حرارة عالية.
– Minimize the frequency of opening the container during transport to maintain internal temperature stability.
– عند الوصول إلى الوجهة, نقل العناصر المبردة على الفور إلى بيئة تخزين مناسبة (مثل الثلاجة أو الفريزر).
– After using the water-filled ice pack, check for any damage or leakage to ensure it can be reused.
– Avoid repeated freezing and thawing to maintain the ice pack’s cold retention effectiveness.
– Dispose of damaged ice packs properly to prevent environmental contamination.
