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

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.

III. The key problems in the producing course

There a lot of flavors of dried beef produced by the different factories such as spiced beef, curry dried beef, spicy dried beef and so on. There are different preparation ways for different flavors, but the processing technologies of dried beef itself are similar, just as :select materials---steam and boil ---- slice --- infuse --- cool -- dry.

There are three common ways to make the beef:1.After preparing the seasoning extract ,stir-frying the sliced beef in the boiler, the time and fire should be noticed.2.After preparing the seasoning extract, boiling the sliced beef in the boiler, the time should be noticed. 3.After preparing the seasoning extract, boiling the slices in the boiler, then infusing it under negative air pressure in order to shorten the time.

These points should be notices when using microwave to process it: 1.When the dried beef is infused and dried, generally, it contains 35%water, if microwave is directly used to dry it, the power should be big, a lot of money should be invested. So for the sake of profit, the water contained should be controlled in about 20%, then dry and sterilize it with microwave. 2. The containers which are used to put the dried beef should adopt the special plastic only for microwave and should often been cleaned and washed. 3.The way that combining microwave and other drying methods can lower the cost and get more profit.4.If there is large amount of water contained, that combing microwave and other drying methods is suggested in odder to obtain the premium and most effective drying effect. There two ways are nature drying and microwave drying.

The former one is economical, when dry and solarize it ,dust and other flies should be prevented, and longer time and more land area is needed ,the latter one can use steam baking house, or electrothermal baking house. General food factories all have steam furnaces, the ready-made steam is used that can save money.

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.
