Energy Efficient Spiral Freezers

A spiral freezer uses a spiral conveyor belt to mechanically transport food products through an efficient freezing process. It is a powerful tool for reducing production time and freezing large quantities of product in a short amount of space. The freezer can be integrated into any food processing system and is an ideal solution for any plant with limited floor space. It also helps reduce energy consumption and improves the quality of the frozen products.

The main function of a spiral freezer is to rapidly decrease a product’s temperature prior to packaging for refrigerated storage or further processing. This allows the product to maintain its shape and texture while being frozen, which is important in the food industry. Unlike tunnel freezers, spiral freezers require a much smaller footprint and are more convenient to install on the manufacturing floor.

This type of freezer is often used in the meat processing industry for freezing sausages, poultry, fish and other foods. It is a popular choice due to its compact design, small footprint and excellent performance. It is also economical and easy to operate. It is also suitable for use in the food service industry, especially for restaurants.

Spiral freezers are used to freeze a variety of different foods such as pasta, shrimps, vegetable rolls, and meat skewers. They are easy to set up and can be integrated into any production line. They are also highly versatile and can be adjusted depending on the type of product being processed. These freezers are also a great choice for food manufacturers who need to preserve their product for long periods of time.

Many facilities are utilizing spiral freezers to quickly cool and freeze products that are then packaged for shipping or refrigerated storage. Unfortunately, these systems can be significant users of energy, resulting in high utility bills for the facility. Through our energy consulting work with food industry professionals who use spiral freezers, Veregy has identified a number of efficiency improvements which can significantly lower these energy costs.

The first step in improving a spiral freezer’s energy efficiency is to determine the optimal parameters for the specific product. This is done by working with plant staff as a team to initially test the freezer. This helps them understand what changes are required in order to achieve the desired product temperatures and optimize equipment operation to save energy.

The next step is to make these parameters part of the plant’s refrigeration control system. This will allow them to be automatically updated based on what the freezer is being used for, minimizing the need for manual intervention. This will also allow for seasonal impacts on load peaks to be taken into account. Ideally, the system will be able to continuously optimize the temperature, fan speed and conveyor belt speed to balance a need for high production rate and energy savings. This requires the right combination of expertise, technology and equipment.
