Quick freezing machine is an emerging liquid nitrogen quick freezing equipment that can freeze frozen items to a temperature of -18 ° C in a short period of time, and quickly pass through the ice crystal production belt (0 to -5 ° C range) within 30 minutes to achieve the goal of slowing down the loss of nutrients and preserving the original flavor. So, is the freezing cost of liquid nitrogen freezer really high?

Calculation of consumption cost of quick freezing machine

The consumption cost of a quick freezing machine is mainly divided into two parts: electricity and liquid nitrogen consumption. Compared to traditional single freezing machines, electricity bills can be basically ignored. The main consumption cost of liquid nitrogen quick freezing is liquid nitrogen.

1、 Basic cost of quick freezing machine

The consumption of liquid nitrogen in frozen food is mainly related to several factors such as moisture content, thickness, initial temperature, whether it comes with packaging, and method; Based on theoretical calculations and years of domestic and international experience, the consumption of liquid nitrogen for 1 ton of frozen products is generally between 0.5-2 tons, and the vast majority of frozen products consume 1-1.5 tons of liquid nitrogen per ton of liquid nitrogen for quick freezing. Some companies intentionally lower their consumption in order to get customers to access their devices, but what we hope for is to provide customers with real information to make rational decisions, rather than being misled into incorrect cost models. We believe that the key for customers to choose liquid nitrogen quick freezing technology is to greatly improve the premium and competitiveness brought by the quality of their products, and the small increase in customer costs can be absorbed and digested by the first two items.

2、 Maintenance cost

Compared to the traditional compressor freezing equipment commonly used in the domestic market, liquid nitrogen quick freezing equipment has better freezing effect, shorter time, energy saving, simple and easy operation, and does not require excessive maintenance costs.

3、 Comparison of freezing time cost

Under the condition of an empty liquid nitrogen container, it can reach -196 in 5 minutes, which can quickly remove heat and effectively cool down food, ensuring that ultra-low temperature and high heat exchange rates achieve true rapid freezing, and the moisture and quality of food are fully preserved. The ice crystals produced by rapid freezing in this way are small and help maintain the original color, flavor, and texture of the food. However, ordinary refrigeration equipment requires 5-6 hours of freezing time, during which water loss is severe and the original color, aroma, and taste of the food cannot be guaranteed.
