تقدير كتلة الجليد الجاف
Use payload weight, حجم المربع, وقت الطريق, seasonal ambient temperature, and carrier limits before the first lane test.
Small-piece frozen route
Frozen Dumplings Cold Chain Packaging Solution
Frozen dumplings are small pieces with thin wrappers. A short thaw can cause clumping, wrapper cracks, تشوه, and bag condensation. The packout must keep the dumplings frozen, protect bags from puncture, and separate dry ice from direct product contact.
نية درجة الحرارةPlan for frozen arrival, عادة -18 C or below for frozen dumpling routes.
مراقبة الرطوبةUse a moisture barrier and separated dry ice chamber so cartons, الأكمام, or bags do not get wet.
Coolant ruleDo not let dry ice or hard frozen packs press directly into loose dumpling bags. Direct pressure can crack wrappers or create hard contact marks.

Choose the packout by route condition
The dry ice amounts below are starting ranges for planning. Final packout should be validated with the exact payload, حجم المربع, ممر الناقل, موسم, and dry ice limit.
| حالة الطريق | نية درجة الحرارة | Tempk packaging setup | Coolant planning range | موقف المبرد |
|---|---|---|---|---|
| التسليم المحلي, 8-18 ح | Frozen loose-piece quality | Insulated carton or EPP box, bag support, حاجز الرطوبة, separated frozen coolant or dry ice. | 1.0-1.8 kg dry ice for 1-5 حمولة كجم, or validated frozen PCM/frozen gel for controlled lanes. | Side or top chamber with divider; prevent direct pressure on dumpling bags. |
| الطرود بين عشية وضحاها, 18-36 ح | -18 C route intent | عزل أكثر سمكا, كيس الثلج الجاف, inner bag protection, limited headspace. | 2.0-4.0 kg dry ice for 1-5 حمولة كجم. | Perimeter dry ice separated from bags; keep bags supported to reduce puncture. |
| Hot lane or 36-48 ح | Validated frozen lane | عزل أعلى, stronger outer carton, انخفاض مساحة الفراغ, route risk check. | 4.0-6.5 kg dry ice for 1-5 حمولة كجم. | If clumping appears, reduce thaw exposure and improve coolant distribution. |

Packout sequence that protects frozen quality
Frozen food returns often come from a small layout failure: direct dry ice contact, الكثير من مساحة الرأس, كرتونة مبللة, or a product stack that shifts during handling.
1
Freeze and load quickly
Do not let dumplings sit warm during picking or kitting; a brief thaw can start clumping before transit begins.
2
Protect bags from puncture
Use inner bracing or a liner so hard coolant and box corners do not tear thin bags.
3
Separate extreme cold
Keep dry ice in a pouch or chamber with a divider so dumplings are not crushed by dry ice blocks.
4
Check loose-piece condition
عند الاستلام, check temperature, clumps, wrapper cracks, bag frost, الثقوب, and dry ice remaining.
Common losses this packout is meant to prevent
Use these receiving checks when adjusting dry ice mass, سمك العزل, or internal separation.
Quality and packaging risks
- Clumped dumplings after partial thaw-refreeze.
- Wrapper cracks from pressure or direct dry ice contact.
- Bag punctures caused by hard coolant blocks or carton corners.
- Surface frost and poor customer presentation from vapor condensation.
