If you are a bakery producer, you may face a dilemma: how to ensure your products do not lose freshness and quality during freezing and transportation? You may have tried traditional freezing methods like air blast or immersion freezing, but are you aware they share a common flaw? They take very long to lower food to suitable temperatures, causing moisture loss and damage to texture and nutrition. This is why you need a more advanced freezing technology: liquid nitrogen cabinet freezers.

Unlock Ultimate Freshness: Explore the Power of Liquid Nitrogen Cabinet Freezers

Liquid nitrogen cabinet freezers are equipment that utilizes liquid nitrogen as the cryogen to rapidly freeze foods in a short time down to below -18°C. This effectively locks in moisture and nutrients to maintain freshness and quality. Liquid nitrogen cabinet freezers have several advantages:

• Speed: They can freeze foods from room temperature down to below -18°C in just minutes, while traditional freezing may take hours or days.
• Energy Savings: They consume minimal liquid nitrogen instead of large electricity for compressors, fans, water cooling towers, etc, reducing energy costs.
• Small Footprint: With a much smaller size than traditional freezers, they save on space costs.
• Flexibility: They can be adjusted for different foods and volumes, and started up instantly without preheating or precooling.

How to Use Liquid Nitrogen Cabinet Freezers to Blast Freeze Egg Tart

To give you an intuitive understanding of liquid nitrogen cabinet freezers, we will introduce a real-world case study: blast-freezing egg tarts with liquid nitrogen cabinets.

Egg tarts are a popular baked good with a crispy pastry shell and creamy egg custard filling. However, they are difficult to preserve properly as they easily become dry and hard, losing their original taste and texture. To solve this, a professional egg tart producer chose liquid nitrogen cabinet freezers to blast-freeze their tarts.

The customer uses SPEEDCRYO's compact liquid nitrogen freezer which has the capacity to load around 2,500 pieces of egg tart each cycle. Before placing the tarts in the freezer, the tarts are filled with egg custard in the pre-formed pastry shells before the custard fully sets. This retains the ideal texture and nutrition.

The tarts are loaded into the liquid nitrogen cabinet freezer, with temperature and duration settings entered before starting the blast freezing cycle. Inside the cabinet, liquid nitrogen is sprayed onto food surfaces and interiors to rapidly lower the temperature below -18°C. Moisture is quickly frozen into tiny crystals rather than large ice crystals, preventing cellular damage and maintaining quality and texture. After about 10 minutes, the tarts reach the ideal frozen state and then can be removed for packaging, storage, and distribution.

Exceptional Quality and Customer Satisfaction of Egg Tart Freezing by Liquid Nitrogen Freezing Equipment

What were the results of blast freezing the egg tarts with liquid nitrogen cabinets? The manager told us their customers are very satisfied with the tarts, which retain freshness and taste even after prolonged storage and transportation. Customers just need to bake or microwave the tarts briefly to enjoy the crispy flaky shell and silky smooth custard-like freshly made. They also shared that the liquid nitrogen method improved product quality and customer satisfaction, while reducing production costs, energy use, and transportation inconvenience, increasing profits, market reach, and competitiveness.

In summary, liquid nitrogen cabinet freezers are advanced equipment ideal for blast freezing baked goods. By rapidly freezing foods down to below -18°C in minutes, they effectively lock in moisture and nutrients to maintain freshness and quality.
