Main features 

Lutai Machinery adopts the unique microwave source and its control technology, thus ensuring that the microwave source system can keep the continuous and stable work all day long for a long time under the various complex environments. The normal service life of the magnetron is ≥1 year; 

It adopts the standard and specially-made efficient microwave transmission system for the even energy feedback of the material, thus ensuring the even drying of the material and avoiding the local excess temperature of the material effectively; 

It adopts the original mathematical model and makes the scientific cavity design in combination with the drying process requirements, thus ensuring the highest dehydration efficiency and avoiding the occurrence of "hot spot", "ignition", "material splash", "burning" and other bad phenomena in the cavity; 

It adopts the safe and reliable microwave shielding design, thus ensuring that the microwave leakage rate is <2mw/cm; It is far superior to the national standard; 

Compared to the traditional drying method (hot air, vapor, electrical heating, etc.), The microwave drying has the following significant characteristics of "high quality, efficiency, energy saving and environmental protection". 

① It can realize no pollution and even drying of the material and can greatly reduce the drying temperature; 

② The drying speed generally increases by several times, and the production efficiency is greatly improved; 

③ The energy consumption for drying generally decreases by more than 50%; 

④ The safe and clean production is realized. 

In the selection of food sterilization equipment, the pasteurization retort is generally selected traditionally. For more difficult sterilization, the majority of people will think of the high temperature sterilization. For the food requiring the low temperature sterilization, the radiation sterilization is first selected. Among the numerous sterilization equipment, the microwave equipment has not been known by everyone in the past few years. With the prominent manifestation of application effect in recent years, the microwave equipment has become the first choice for the enterprise. Therefore, the sterilization advantage of microwave equipment is most significant among many sterilization methods. 

1. Disadvantage of pasteurization and steam sterilization: Since the steam heat is transmitted from outside to inside, the sterilization time is long, so it will produce the adverse effect (such as loss of aroma-producing substance and sensitive amino acid) upon the material flavor and lead to the large energy consumption, complicated operation and poor production continuity. 

 2. Disadvantages of irradiation technology food sterilization method: It will destroy the molecular structure of the material and produce the irreversible damage. It will produce the irradiation residues and destroy the original fragrance of the food; thus making the color and luster of some food shallow or fade; Since the irradiation dose shall not exceed 10kGy, it is not thorough to kill some stubborn and harmful bacteria. The scientific community still has the dispute about the safety of the irradiated food, and the various countries in the world hold the prudent attitude towards the irradiated food. For example, Japan prohibits the import and sales of irradiated food in the Second World War. Meanwhile, many consumers are conservative to buy the irradiated food. 

3. The microwave sterilization has such advantages as fast speed, energy saving, even heating, low treatment temperature, preservation of flavor and nutrient, safety and no residue, no pollution, easy automatic production, etc. The microwave is widely applied to the food industry and can be used for the food sterilization and preservation, drying, curing, baking, puffing, modification, acceleration of chemical reaction, etc. 

4. In addition, the microwave treatment of food will not produce the harmful residues. It also has the following advantages: 1. It is easy to use, so the microwave equipment can be installed and used in the food workshop. For the irradiation sterilization, there shall be a professional irradiation plant. However, the construction of irradiation plant implements the strict licensing system in our country, and the number of irradiation plants is small, so the food has to be transported to the farther irradiation plant for sterilization, thus leading to the inconvenience, increasing the transportation cost and wasting the manpower. 2. It can reduce the sterilization cost. It only takes RMB 0.1-0.2 of electric charge to use the microwave sterilization equipment for sterilization of power, massive and particle food and treatment of one kilogram of material, with the cost being lower than the irradiation sterilization cost.
