2.Introduction:

Dried beef is savory, making with various condiments with many technologies, so there are a lot of flavors to sufficiently satisfy the people everywhere. People are fond of dried beef as a sock during leisure time. In the past time, dried beef was produced by solarizing under the sun, drying or warming it by burning the soil, in these ways, the quality is bad and lead to serious pollution. Later, there were some factories to refine the technology that built steam baking room, so that the sanitary condition got improved and the dust, bacteria was decreased. However, there are three big problems in it. First: taking long time to dry it. After soaking and drying the beef, the water in it is about 30%, if it should meet the requirement that only 10%-12% water in it ,it must take a long time that limit the improvement of output. Second: This method consumes more vapor and electricity that result in high cost and low profit. Third: The

bacteria can’t be sterilized thoroughly, the sanitary index can’t meet the requirement.

Our company introduces microwave technology overseas in 21 century, and researched and developed the equipment for processing the meet in the production line(drying and sterilizing with microwave).During the course of using it, that equipment is proved to thoroughly change the quality, output and sanitary index, and solve the problem of coking that many factories failed to work out during many years.

I. Introduction to the equipment

It adopts the technology of radiation with several microwave sources and it is equipped with imported temperature controller, The heat is distributed evenly. It is installed suppresser against the microwave leakage at the heater’s inlet and outlet for the materials. Its leakage index has met America UL standard, we can assure it is absolutely safe. During the course of roasting, the dried beef on the trays can rotate at stepless speed that is convenient for the adjustment of various technologies.

II. The features of drying and sterilizing

1.High efficiency, energy saving, evenly heating. Microwave has excellent penetrability, It can penetrate into the inside of the dried beef, heating it inside and outside at the same time, besides, only the dried beef which is heated can absorb the microwave energy. Therefore, it has high thermal efficiency and the heat is homogeneously distributed that diminish the loss of heat energy. Compared with general electrothermal drying method, 1/3 to 1/2 of electricity can be saved.

2.Good result of low-temperature sterilization, both thermal effect and nonthermal effect. Compared with regular method, it is characterized by low temperature and fast speed. It can keep the origional color,pleasant smell, taste without spoiling the nutritious components and has good expanding effect. The taste of the food is excellent.

3.It is convenient and quickly to control it without being affected by the weather. There is no heat inertia of the microwave equipment. The microwave power and transmission speed can be regulated continuously. This equipment can keep producing last for 24 hours.

4.There is no heat radiation of the microwave equipment itself when heating, so this can improve the work condition. The microwave leakage conforms to national standard. It has compact structure with less land area occupied.

The principle of microwave drying

Microwave is a sort of electromagnetic wave which frequency is 300MHz to 300GHz .The water molecule in medium materials is polar molecule,under the effect of the rapid change of electromagnetic field,its polarity orientation will alter with the changes of the external electric field with the high-speed,causing the movement and friction of molecule.so that the microwave field energy can be converted to heat energy in medium to rise the temperature of materials.accomplishing heating ,puffing and a series of physical and chemical processes ,and so ,microwave heating is achieved.

The principle of microwave sterilizing

Microwave sterilizing is the result of combined action of the thermal effect of electromagnetic fields and the biological effect.Thermal effect of microwave on the bacteria denatures the protein of bacteria ,and make the bacteria lost the condition of nutrition,reproduction and survival so as to die .The biological effects of microwave on the bacteria is that the microwave electric field changes the potential distribution of cross-section of the bacterial cell membrane and impacts the concentration of electron and ion around the membrane ,and changes the permeability of cell membranes ,therefore the bacterium become innutrient and lost normal metabolism.The structure and function of bacterium fall into disorder ,and theirs growth are inhibited ,as a result they are dead.Moreover ,nucleic acid genetic(RNA) and deoxyribose acid (DNA),which decide the normal growth and stability of bacterial,are curly-shaped macromolecule made of a number of linked compactly hydrogen bond .The microwave can be strong enough to make hydrogen bond stack ,rupture and recombine ,and induce intragenic mutation or chromosome aberration and even rupture.

IV. other application field

Microwave energy technology is able to successfully dry and sterilize the dried beef as well as the dried pork, chicken. It also can be used to ripe and sterilize the pastry, bake the melon seeds, process the bean flour and other foodstuff.
