Rice and Wheat Bran Powder Sterilization Machine

Microwave technology is commonly used for sterilization purposes, including the sterilization of rice and wheat bran powder. The process of using microwaves to sterilize these food products is known as “microwave sterilization” or “microwave pasteurization.”

Here’s how the sterilization machine works:

1. Microwave Technology: Microwave sterilization utilizes electromagnetic waves at a frequency of 2.45 GHz (gigahertz) to heat and sterilize food products. This technology is effective because microwave radiation can penetrate the food and heat it from the inside, which makes it a rapid and uniform method for sterilization.
2. Preparation: Before the microwave sterilization process, the rice and wheat bran powder must be prepared. This involves grinding or crushing the grains into a fine powder and ensuring that it is evenly distributed in the sterilization containers or trays.
3. Loading: The prepared rice and wheat bran powder is loaded into microwave-safe containers or trays. These containers should allow microwave radiation to penetrate the food evenly.
4. Microwave Treatment: The containers with the food are then placed inside the microwave sterilization machine. Microwaves are emitted and absorbed by the food, causing the water molecules within the food to vibrate and generate heat. This internal heating is what leads to sterilization. The microwaves are carefully controlled to ensure that the food is heated to the required temperature for sterilization.
5. Temperature Monitoring: During the microwave treatment, it is crucial to monitor the temperature of the food. The goal is to reach a temperature that is sufficient to kill harmful microorganisms, but not so high that it damages the quality of the food. Temperature sensors or probes may be used for this purpose.
6. Cooling: After the sterilization process, the food needs to be rapidly cooled to prevent overcooking and to maintain its quality.
7. Packaging: Once the sterilization and cooling process is complete, the rice and wheat bran powder can be packaged in aseptic containers to maintain their sterility until use.
8. Bran stabilization function. The microwave could make the bran materials stabilization. And the Extruder Machine could also make that function.

Microwave sterilization has several advantages, including speed, energy efficiency, and the ability to maintain the nutritional and sensory quality of the food better than some other sterilization methods. However, it is important to note that the process must be carefully controlled to ensure that the food reaches the necessary sterilization temperature to make it safe for consumption.

Before using microwave technology for food sterilization, it’s essential to comply with food safety regulations and guidelines to ensure the safety and quality of the final product. Additionally, the specific parameters for the microwave sterilization process depends on the type and quantity of food being processed, so it’s important to tailor the process to the specific requirements of the product.
