Food processing equipment technology and process progress are of great significance to environmental protection

Food production is inseparable from energy, and wastewater and waste residue are easily generated during the process. If improperly handled, they will have a great impact on the surrounding environment. The key to energy conservation and environmental protection in the food industry lies in equipment technology improvement, starting from the source.

Food processing equipment technology progress saves energy

Food production processes, such as heating, cooking, tempering, cooling, etc., consume a lot of energy, but if the production process is optimized, a lot of energy can be saved. Different food processing equipment produces very different energy consumption. Similarly, in the chocolate tempering process, the use of modern equipment can reduce energy consumption by 50-80%, and intelligent control can reduce the energy consumption of the oven by 50% or more.

Energy saving also includes packaging materials. The application of ultrasonic heat sealing technology saves packaging materials. First of all, the seams of the heat-sealed joints produced by this process are narrower, so the required film materials can be better utilized, and the number of tubular bags that can be made from each roll of film has also been greatly increased. On the other hand, the use of this process also makes it possible to use thinner and more economical films for product packaging, because there is no need to use an additional heat-sealing layer on the film. By using cheaper and thinner films, 30% of materials and costs can be saved.

Ultrasonic welding can also be used to join packaging materials that are contaminated by products, and can ensure the cleanliness and tightness of the joints. This method can reduce the volume of the top space of the package and thus save packaging materials. Compared with heat sealing and cold sealing, this method can also increase the output of qualified products. Compared with the hot contact method using a heating tool, ultrasonic welding can save up to 80% of energy.

Optimize food processing technology to save resources

Lightweighting is one of the development trends of modern food packaging, which can be seen from small bottles of water, mini wine, etc. On the one hand, lightweighting helps to save raw materials and energy, optimize handling operations and reduce transportation costs; on the other hand, it also avoids waste. At present, whether it is metal cans, plastics or glass packaging, all of them are becoming lighter and lighter, but at the same time have better packaging performance and packaging stability.

In addition, optimizing food processing technology to save energy is also reflected in water treatment. As we all know, water is indispensable for making food. Not only does the production itself use water, but the finished product also contains water, and many cleaning operations in the food processing and packaging process also require water. Water is one of the precious resources that humans need to survive. Reducing waste and avoiding pollution is the social responsibility that every food company should bear.

Extraction, treatment and provision of clean water involve huge energy consumption, including subsequent wastewater treatment. Therefore, the in-situ cleaning device used in food processing and packaging machinery is currently all the rage. It not only has an adapted time optimization process, but also can save resources consumption to a wide range, such as water, energy, detergents and disinfectants, thereby protecting the environment, saving resources, and reducing procurement costs and the costs of detergents and sewage treatment.

The natural resources on the earth are not inexhaustible. If humans use these resources while polluting without restraint, they will destroy themselves. Food is an indispensable item in the lives of ordinary people. How to adopt sustainable resource utilization and energy-saving process measures on all process lines is something that food industry participants have to consider and is also a core challenge.

Intelligent control and automation engineering, drives, compressors, fans or pumps are typical solutions for saving energy and resources and improving energy efficiency. However, it is not enough to focus only on energy-saving drives. We must also pay attention to packaging and other energy consumption produced during food processing.
