Many people believe that tunnel-type liquid nitrogen quick freezing machines are more automated, advanced, and superior, but in reality, they are only suitable for long-term continuous operation and products with high production capacity. When selecting a liquid nitrogen blast freezing machine, Sichuan Aosituo recommends considering factors such as product type, production capacity, liquid nitrogen consumption, floor space, and budget.
- Applicable Products
Cabinet-type liquid nitrogen fast freezing machine: Suitable for products with multiple varieties, specifications, and small batches, as well as extremely thick products (requiring 40~60 minutes of freezing time).
Tunnel-type liquid nitrogen fast freezing machine: Suitable for single-product, large-batch production, capable of continuous operation for over 8 hours, aiming for the lowest unit cost.
- Production capacity
The cabinet LN2 flash freezer involves batch loading, where pallets are pushed in, the door is closed for rapid freezing, and after freezing, the pallets are removed before the next batch is loaded. It has relatively low production capacity.
The tunnel LN2 flash freezer is a continuous conveying system where products enter at one end and exit at the other, passing through the low-temperature zone on the conveyor belt. It offers high production capacity.
- Liquid nitrogen consumption
According to the on-site user data of Sichuan Aosituo, the average consumption ratio for liquid nitrogen flash freezing is: 1 kilogram of product consumes 1 to 1.3 kilograms of liquid nitrogen.
Among them, the liquid nitrogen consumption of cabinet-type liquid nitrogen quick-freezing machines is relatively stable, while tunnel-type liquid nitrogen quick-freezing machines exhibit lower consumption during long continuous operation and higher consumption during short-term operation. If your production is intermittent, the cabinet type liquid nitrogen blast freezer machine would be more suitable.
- Floor area
Tunnel-type liquid nitrogen rapid freezing machines require a large footprint. If your workshop space is limited, a cabinet-type LN2 quick freezing machine would be more suitable.
- Budget
Tunnel-type liquid nitrogen rapid freezers are more expensive than cabinet-type ones. If your budget is limited, the cabinet-type LN2 quick freezer would be more suitable.
