With the development of the global economy and the improvement of living standards, people’s demand for food is also increasing. In order to meet people’s demand for food, the food processing industry is receiving more and more attention and investment. Refrigeration equipment is an integral part of food processing. As refrigeration equipment can refrigerate or freeze food products, thereby extending the shelf life of food and maintaining the freshness of food.
Most foods need to be refrigerated or frozen during processing. The following is to introduce the differences and applications of three common quick freezers in food processing. Would help to choose a more suitable one for your business.
Contact plate freezer, tunnel freezer, and spiral freezer are three common quick freezing technologies, which are widely used in food processing.
1. Contact Plate freezer
Plate freezer is a quick freezing technology widely used in the food processing industry. In plate quick freezing, the food is placed on a plate and then cooled rapidly by a freezer. This technology allows food to reach freezing temperatures quickly, thereby preventing further growth of bacteria and microorganisms in the food, while preserving the food’s nutritional content and taste. Plate quick freezing is widely used in the freezing of meat, aquatic products, fruits, vegetables and other foods.
2. Tunnel freezer
Tunnel freezer is a technology in which food is placed on a conveyor belt and then cooled rapidly by a cooling fan. This technology can bring food to freezing temperature and maintain the freshness and taste of food. Tunnel quick freezing is widely used in the freezing of meat, aquatic products, fruits, vegetables and other foods.
The advantage of tunnel quick freezer is that it has a high production capacity and can be mass-produced. In addition, tunnel freezers save energy because they use the heat released from the food and reduce the energy consumption of cooling fans.
3. Spiral freezer
Spiral freezer is a technology that places food in a spiral pipe and cools the food rapidly through a cooling fan. This technology can bring food to freezing temperature quickly and maintain the freshness and taste of food. Spiral quick freezing is widely used in the freezing of meat, aquatic products, fruits, vegetables and other foods. The advantage of spiral freezer is that it can be produced in large quantities, while saving energy and taking up less space.
In food processing, the use of refrigeration equipment is very important. Freezing equipment can quickly reach the freezing temperature of food, thereby extending the shelf life of food and maintaining the freshness of food.
Generally speaking, different quick freezing equipment has its own advantages and disadvantages and applicable fields. When choosing quick freezing equipment, it is necessary to consider multiple factors, such as production capacity, cost, space, and energy costs. In order to choose the equipment that best suits your production needs.
