The effect of microwave drying equipment power on product drying effect!
Microwaves have the property of selective heating of substances: for example, water is a substance with very strong molecular polarity, and it is more susceptible to microwave heating. Therefore, the higher the water content, the easier it is to absorb microwaves, and the heat is faster and faster. As moisture content decreases, its ability to absorb microwaves also decreases.
In the early stage of product drying, the moisture content in the product is very high, and the power of the microwave equipment has a high impact on the drying effect (water is the best medium for absorbing microwaves). With the extension of time, most of the microwave energy is absorbed by the water and the water quickly migrates. And evaporation; In the late drying period of the product, with the reduction of moisture, the required microwave energy is also less, and the microwave equipment power can be properly diluted. However, there are many products that cannot be dried under high temperature conditions. Microwave vacuum drying equipment is needed at this time: under vacuum, the boiling point of water is reduced, and nutrients, vitamins, etc. can be well maintained. At the same time, in the vacuum system, the content of air in a unit volume is lower than that in the atmosphere. Drying the food in this relatively oxygen-deficient environment can reduce or even avoid the opportunity of oxidation of fat in the food, pigment browning or other oxidative deterioration, Therefore, some products with high added value, such as Cordyceps and Ginseng, are microwave vacuum dried.
Microwave drying equipment is a non-standard customized product. The specific power size and design need to be combined with the product technology, so that the effect will be maximized.
Permanent magnet synchronous motor (PMSM) is a synchronous motor that generates synchronous rotating magnetic field by permanent magnet excitation. The permanent magnet produces a rotating magnetic field as a rotor. The three-phase stator winding induces a three phase symmetrical current through the armature reaction under the action of a rotating magnetic field. It is 2% to 5% more efficient than high efficiency asynchronous motors and its power factor is over 10%.In recent years, the technology of permanent magnet motor has developed rapidly and its application has become more and more extensive.In recent years, the technology of permanent magnet motor has developed rapidly and has been widely used in all walks of life. We know that over 60% of industrial motor-driven system energy consumption involves fluid handling. Pumps, fans, compressed air and refrigeration devices account for 61.0% of the industrial motor energy consumption. Promoting the use of permanent magnet motors under the application of pumps can reduce social energy consumption and have a broader use prospect. This product can be customized according to the needs of users.
Product features:
1. High efficiency and energy-saving
The permanent magnet has its own magnetic field with no excitation and has a high power factor. Under load fluctuation, the average power output is high and the loss is small (motor's core loss / bronze loss).
2. Compact and flexible.
The power density is large and the volume is small under the same power.
3. High reliability
The power density is large and the volume is small under the same power.
The loss is small, the temperature rise is low, and the vibration noise is small.
Eliminating the excitation system has reduced the failure rate of the equipment.
