Estimer la masse de glace carbonique
Utiliser le poids de la charge utile, taille de boîte, temps de parcours, 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, déformation, and bag condensation. The packout must keep the dumplings frozen, protect bags from puncture, and separate dry ice from direct product contact.
Intention de températurePlan for frozen arrival, communément -18 C or below for frozen dumpling routes.
Contrôle de l'humiditéUse a moisture barrier and separated dry ice chamber so cartons, manches, or bags do not get wet.
Règle du liquide de refroidissementDo not let dry ice or hard frozen packs press directly into loose dumpling bags. Direct pressure can crack wrappers or create hard contact marks.
Réception du chèqueConfirmer la température du produit, dry ice remaining, visible thaw, pack condition, and coolant position together.
Choisissez le pack par condition d'itinéraire
The dry ice amounts below are starting ranges for planning. Final packout should be validated with the exact payload, taille de boîte, carrier lane, saison, and dry ice limit.
| État de l'itinéraire | Intention de température | Tempk packaging setup | Coolant planning range | Emplacement du liquide de refroidissement |
|---|---|---|---|---|
| Livraison locale, 8-18 h | Frozen loose-piece quality | Insulated carton or EPP box, bag support, barrière contre l'humidité, separated frozen coolant or dry ice. | 1.0-1.8 kg dry ice for 1-5 kg de charge utile, or validated frozen PCM/frozen gel for controlled lanes. | Side or top chamber with divider; prevent direct pressure on dumpling bags. |
| Colis de nuit, 18-36 h | -18 C route intent | Isolation plus épaisse, pochette de glace carbonique, inner bag protection, limited headspace. | 2.0-4.0 kg dry ice for 1-5 kg de charge utile. | Perimeter dry ice separated from bags; keep bags supported to reduce puncture. |
| Hot lane or 36-48 h | Validated frozen lane | Isolation supérieure, stronger outer carton, espace vide réduit, route risk check. | 4.0-6.5 kg dry ice for 1-5 kg de charge utile. | 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, trop d'espace libre, un carton mouillé, 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
A la réception, vérifier la température, clumps, wrapper cracks, bag frost, perforation, and dry ice remaining.
Pertes courantes que ce pack est censé éviter
Use these receiving checks when adjusting dry ice mass, épaisseur d'isolation, or internal separation.
Risques qualité et emballage
- 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.
