The Advantages of Spiral Freezer Comparison with Tunnel Freezer

The quick freezer is a high-efficiency freezing equipment that can freeze a large number of products in a short time. The center temperature of the quick frozen items is - 18 °, so that the nutrients will not be lost, and the product will not lose its color and crystal.

Tunnel freezer and spiral freezer are the two main types of them. Tunnel freezer is an efficient quick freezing device with simple structure, which is suitable for quick freezing of pastry, ready meals, meat and other foods. While the spiral freezer requires a small area and has a high degree of automation. The position of inlet and outlet can be adjusted in any direction.

And for comparison, here are some advantages of spiral freezer as below:

1.      The structure design is more optimized, the floor area is smaller, and the quick freezing efficiency is higher, so as to meet the requirements of the customers who’re looking for large capacity.

2.      Higher airtightness, less contact with the outside world, higher refrigerant utilization ratio, and more cost saving.

3.      Single drum and double drum spiral freezer can be customized according to the customer's production requirements to solve the problem of product freezing capacity.

4.      The length of the mesh belt is longer, which increases the freezing contact time, the freezing quality and the capacity per unit time.

5.      There are more diverse ways of feeding and discharging, including low in and low out, high in and low out, low in and high out, straight type, U type, L type and so on, which can meet the different needs of different frozen products and make it easier for different production lines for seamlessly connect. The internal cylindrical freezer generally saves space, reduces space waste and increases utilization rate.
