Cara Menggunakan Es Kering dalam Pendingin untuk Pengiriman yang Aman dan Efisien

Shipping temperature-sensitive items, such as perishable food, vaksin, and biotech samples, requires reliable cooling solutions. Using coolers with dry ice packs is an effective way to keep items frozen for extended periods without the mess of melting ice. Dalam panduan ini, we will cover the steps on how to use dry ice in coolers dengan aman, praktik terbaik, and the benefits it offers in modern cold chain logistics.

Whether you are shipping seafood, Farmasi, atau barang yang mudah rusak lainnya, dry ice is one of the most efficient ways to maintain low temperatures. Pada -78,5°C (-109.3° f), dry ice is significantly colder than regular ice, making it ideal for shipments that require extended freezing. This guide will walk you through the process of using dry ice in coolers for safe and efficient shipping.

• How dry ice works in coolers

• Best practices for safe dry ice handling

• How to pack coolers efficiently with dry ice

• Comparing dry ice and regular ice for different shipping needs

• Key regulations and compliance for shipping with dry ice

How Does Dry Ice Work in Coolers?

Es kering adalah karbon dioksida padat (Co₂) and sublimates directly into gas at a temperature of -78.5°C (-109.3° f). Tidak seperti es biasa, yang meleleh ke dalam air, dry ice does not leave any residue, making it ideal for long-duration shipments. The cooling effect occurs as dry ice absorbs heat from the surrounding environment, keeping items inside the cooler frozen for much longer than regular ice.

Key Benefits of Using Dry Ice in Coolers

• Durasi pendinginan yang diperpanjang: Dry ice keeps contents frozen for longer periods compared to regular ice, which is crucial for long-distance shipments.

• Tidak Ada Residu Air: Karena es kering menyublim menjadi gas, there’s no risk of water damage to your goods, which is especially important for sensitive items.

• Efficient Space Utilization: Dry ice takes up less space than regular ice, allowing you to pack more items without sacrificing cooling efficiency.

• Better for Sensitive Items: Dry ice is preferred for shipping pharmaceuticals, vaksin, and biotech samples, as it maintains a constant low temperature.

Cara mengemas pendingin dengan es kering: Panduan langkah demi langkah

Melangkah 1: Select the Right Cooler

Choose a cooler that is well-insulated and can accommodate both your items and the dry ice. A high-quality cooler helps retain cold for longer and is essential for ensuring the dry ice lasts for the necessary duration.

• Kualitas isolasi: Select coolers that feature thick insulation to prevent temperature fluctuations.

• Ventilasi: Es kering sublimat ke dalam gas co₂, so ensure your cooler has a vent or that you leave a small gap to allow the gas to escape.

Melangkah 2: Tangani es kering dengan aman

Always wear insulated gloves or use tongs to handle dry ice. Its extreme cold can cause frostbite if touched directly.

Melangkah 3: Pack the Cooler Efficiently

Layer the dry ice at the bottom of the cooler, as cold air naturally sinks. Place insulating materials between the dry ice and your goods to prevent direct contact. This helps avoid freezing the contents or damaging them.

• Layering: For perishable goods, layer insulation like cardboard or towels to protect them from direct contact with the dry ice.

Melangkah 4: Tutup pendingin dengan benar

Once the cooler is packed, ensure it is sealed tightly but not airtight. Dry ice needs a way to release CO₂ gas to avoid pressure buildup, which could lead to dangerous situations.

Melangkah 5: Pantau suhu

For sensitive items, it’s recommended to use temperature monitoring devices to track the conditions inside the cooler during transit.

Melangkah 6: Dispose of Dry Ice Safely

Allow the dry ice to sublimate in a well-ventilated area. Never dispose of it in a sealed container, as the buildup of gas can cause the container to explode.

Es kering vs.. Es biasa: Which Should You Use?

Best Practices for Using Dry Ice in Coolers

• Use the Right Amount: Untuk pengiriman panjang, calculate the amount of dry ice based on the temperature and duration of the journey. Khas, 5-10 pounds of dry ice are needed per 24 jam.

• Pastikan ventilasi yang tepat: Always make sure that the cooler has proper ventilation to release CO₂ gas. Failure to do so can cause dangerous pressure buildup.

• Layer Correctly: Place dry ice at the bottom for frozen items and use insulating layers between the dry ice and the goods to protect them.

Regulations for Shipping with Dry Ice

Saat pengiriman dengan es kering, there are specific regulations to follow, especially when shipping via air.

• UN1845 Labeling: Dry ice shipments must be labeled as “Es Kering UN1845” atau “Karbon dioksida, solid.” Ensure that the net weight of the dry ice is clearly marked on the package.

• Peraturan IATA: If shipping by air, certain restrictions apply, including weight limits (MISALNYA., 2.5 kg per passenger on consumer airlines).

• Ventilation and Packaging: Use proper packaging materials that allow the CO₂ gas to escape, such as corrugated boxes with ventilation holes.

2025 Tren logistik rantai dingin

Saat kita pindah 2025, there are several trends shaping the cold chain industry, termasuk:

• Bahan ramah lingkungan: With increasing demand for sustainability, companies are moving towards recyclable materials and reducing single-use plastics in packaging.

• Pemantauan Suhu Cerdas: Real-time monitoring with Bluetooth-enabled devices is becoming more affordable and widely adopted, ensuring accurate tracking of shipments.

• Ready-to-Use Kits: Preassembled cold chain solutions are gaining popularity, saving time and minimizing errors during packing.

FAQ

Q1: Berapa banyak es kering yang saya perlukan untuk pendingin saya?

A good rule of thumb is to use 5-10 pon es kering per 24 jam pengiriman. Adjust based on the cooler size, lamanya, dan kondisi suhu eksternal.

Q2: Bisakah saya menggunakan es kering untuk pengiriman makanan?

Ya, dry ice is ideal for shipping perishable foods, especially those that need to stay frozen, such as seafood, daging, dan es krim.

Q3: How do I handle and dispose of dry ice safely?

Selalu kenakan sarung tangan berinsulasi saat menangani es kering. Dispose of it by allowing it to sublimate in a well-ventilated area, ensuring it has no contact with airtight containers.

Kesimpulan

Dry ice is a reliable and effective solution for keeping items frozen during long shipments, whether for food, Farmasi, or biotech samples. By following proper packing techniques, ensuring correct ventilation, and adhering to shipping regulations, you can safely and efficiently use dry ice for cold chain logistics.
