Product Introduction
Pumpkin Seed Seed Sterilization and Drying Equipment
Microwave sterilization equipment utilizes the biological effects of microwaves on cells, where the microwave electric field changes the potential distribution of the cell membrane cross-section, affecting the electron and ion concentration around the cell membrane, thereby altering the permeability of the cell membrane, causing malnutrition, inability to metabolize normally, disruption of cell structure and function, inhibition of growth and development, and death.
Insects and bacteria in nuts absorb microwave energy. Proteins in the body are subjected to both non-polar thermal motion and polar rotation, causing changes or damage to their spatial structure and resulting in protein denaturation. After protein denaturation, its solubility, viscosity, swelling, permeability, and stability will undergo significant changes, and it will lose its biological activity.
Pumpkin seed sterilization equipment can maintain the original flavor of the product, without discoloration or deformation, making it the best sterilization equipment
Characteristics of microwave sterilization for pumpkin seed kernel sterilization and drying equipment
1. Short time and fast speed
Conventional thermal drying sterilization involves transferring heat from the surface of an object to its interior through methods such as heat conduction, convection, or radiation. It often takes a long time for the interior of the object to reach the required dryness and sterilization temperature. The medium is composed of polar and non-polar molecules. Under the action of an electromagnetic field, these polar molecules shift from their original random distribution state to orientation according to the polarity of the electric field. Under the action of high-frequency electromagnetic fields, these orientations constantly change according to the frequency of alternating electromagnetic waves, causing molecular motion and mutual friction to generate heat. At this time, the field energy of the alternating electric field is converted into thermal energy inside the medium, causing the temperature of the medium to continuously rise. Therefore, microwave heating is caused by the loss of electric field energy by the medium material itself and generates heat. So the microwave heating treatment time is greatly shortened, and under a certain power density intensity, satisfactory results can generally be achieved in just a few seconds or minutes.
2. Low temperature drying sterilization to maintain nutritional content
Microwave has a dual bactericidal effect of rapid heating with thermal effect and non thermal effect. Compared with conventional thermal drying and sterilization, it can achieve the desired drying and sterilization effects at relatively low temperatures and in a shorter time. The general sterilization temperature is between 65-70 ℃, 75-80 ℃, or 103-121 ℃, with a duration of 3-8 minutes, and can retain more food nutrients and flavors such as color, aroma, taste, and shape. For example, vegetables treated with conventional heat can retain 46-50% of vitamin C, while microwave treatment can achieve 60-90% of vitamin C retention. Pig liver treated with conventional heating has a vitamin A retention value of 58%, while microwave heating can achieve 84%.
3. Save energy
Microwave energy conversion efficiency is high, generally above 70%. Microwaves directly process food, and the heating box itself is not heated, so there is no additional heat loss, so it is energy-saving and can generally save 30-50% of electricity.
4. Uniform and thorough
Conventional thermal drying and sterilization start from the surface of the material and then transfer to the interior of the material through thermal conduction. There is a temperature difference between the inside and outside of the material, resulting in poor consistency in drying and sterilization effects. In order to maintain flavor and shorten processing time, the internal temperature is often not sufficient, which affects the drying and sterilization effects. Raising the processing temperature can improve this phenomenon, but it leads to a decrease in the quality of the surface of the item, such as color, aroma, taste, and shape. Microwaves have penetrative properties, acting simultaneously on both the surface and interior, ensuring that both internal and external temperatures reach the required values, resulting in uniform and thorough drying and sterilization.
5. Easy to control and achieve automated production
Microwave food drying and sterilization equipment is easy to operate, easy to control, without thermal inertia, and can be processed according to different food process specifications, reducing production operators and lowering production costs.
6. Simple equipment and advanced technology
Compared with conventional sterilization, microwave equipment does not require boilers, pipeline systems, coal yards, and transportation vehicles. As long as it has basic water and electricity conditions, there are no special requirements for the factory building, with less investment and quick results.
7. Improve working conditions and save land area
Microwave equipment has no high temperature, helpless heat, does not generate heat itself, and has no thermal radiation. It can greatly improve working conditions, and the equipment structure is compact, saving factory space.
