If you are planning to purchase a spiral freezer for your business, you need to make sure you purchase the right one. There are two types you will find and information about each one below.

Self-Stacking

A self-stacking spiral freezer is designed to freeze food quickly and efficiently. The airflow design of this freezer completely freezes the products in a center drum that is easy to clean and maintain. 

This freezer has tiers that rest on each other with a belt that is self-contained. You do not have to use any kind of supports or stationary rails with this type of freezer. This reduces the chance of jamming while it is operating. Each spiral on this freezer is designed so that it meets your requirements. One common design uses a conveyor belt that has side links and each belt stacks upon each other as the freezer spirals. 

A self-stacking spiral freezer can freeze a variety of products, such as fish, a variety of cuts of meat, chicken, already prepared foods, bakery items, juice concentrates, and ice cream. As long as the product can fit on the belt, it can be frozen with this freezer. The freezer will have a control panel that allows you to set the temperatures and monitor them. 

Non-Self Stacking 

The non-self-stacking spiral freezer is an inline system and can freeze a variety of food products. This freezer has a conveyor belt made of mesh that goes into a spiral. The freezer consists of the conveyor system, insulated enclosure, a control system, and an air-handling system. 

Fans are used to pressurize the air through the spiral coils, and the air is then directed onto the product you are freezing. This maximizes the freezing time and ensures the products stay frozen at the right temperature. The floor where the freezer is placed should be insulated, which can be done by using polyurethane laminated panels. Common floor materials used are concrete, stainless steel, or aluminum. The company that installs the spiral freezer may suggest installing heating cables under the floor. 

As with the self-stacking spiral freezer, this freezer will also have a control panel. This allows you to set the temperature, change the temperature, if needed, and more. This also allows you to easily monitor the temperature. 

Talk with the salesperson where you plan to purchase your spiral freezer, and they can give you much more information about each of these.
