Cold powder microwave sterilizer

Microwave sterilization of liangfen is a method of using microwave technology to sterilize liangfen. This method has the advantages of high efficacy, environmental friendliness, and no residue, and will not affect the taste and nutritional content of the jelly.

The principle of microwave sterilization is to use the energy of microwaves to penetrate substances, causing the water in the bacterial body to evaporate and the temperature to rise, ultimately leading to bacterial death. Compared with traditional heating sterilization, microwave sterilization has higher efficiency and wider sterilization range, which can better guarantee the safety and quality of food. Using this microwave sterilization equipment can not only extend the shelf life of Liangpi, reduce food waste, but also improve consumers' eating confidence. At the same time, the research, development and application of the equipment also promoted the upgrading and development of Liangpi industry.

In short, the research and application of microwave sterilization equipment for liangfen provide strong guarantees for the healthy development of the liangfen industry. In the future, with the continuous advancement of technology and the expansion of application fields, it is believed that this equipment will be widely used in more food processing fields, making greater contributions to food safety and human health.

The principle of microwave sterilization mainly includes thermal and non thermal effects. Thermal effect refers to the ability of microwaves to rapidly rotate and rub polar molecules (such as water molecules) in food, generating heat and causing a rapid increase in temperature inside microorganisms, resulting in protein denaturation and loss of biological activity. The non thermal effect refers to the change in cell membrane potential caused by microwave electric fields, affecting the permeability of the cell membrane, leading to microbial malnutrition, inability to metabolize normally, and ultimately death. ‌

The specific process of microwave sterilization

Thermal effect: Under the action of microwave field, polar molecules (such as water molecules) in food will rapidly rotate with the change of microwave electric field, generating heat, causing the temperature inside microorganisms to rapidly rise, causing protein denaturation and loss of biological activity.

Non thermal effect: Microwave electric fields can alter the cell membrane potential, affect the permeability of the cell membrane, lead to microbial malnutrition, prevent normal metabolism, and ultimately result in death.

Application scope and effectiveness of microwave sterilization

Microwave sterilization is suitable for liquid and solid materials, and has the advantages of good sterilization effect, short time, and low temperature. Under the same sterilization conditions, microwave sterilization requires shorter heating time and relatively lower heating temperature, but has better sterilization effect.
