Beef Jerky Microwave Drying Equipment

Beef has high protein content, low-fat content, and delicious taste, known as the “meat in the pride.” While beef jerky retains the nutrition and taste of beef and is convenient to preserve and carry, it makes it more popular.

The production of beef jerky, first you must choose the best raw materials, followed by strict production process and time, each process must be closely controlled, beef jerky microwave drying equipment greatly simplifies the process.

Advantages of beef jerky microwave drying equipment:

  1. The quality of the product that beef jerky microwave dryer produced is excellent. Microwave can penetrate into the beef jerky, heating inside and outside simultaneously, dry evenly. Low temperature and fast speed can keep the original color, flavor, and taste of the food without damaging the nutrition. At the same time, it has a bulking effect, beef jerky tastes better.
  2. A microwave drying machine for beef jerky can save energy. Only beef jerky absorbs microwave energy, heat loss is small.
  3. Microwave beef jerky drying equipment can work continuously. Out of the box, no thermal inertia effectively improves production.
  4. The microwave beef jerky drying machine improves working conditions. There is no thermal radiation, and microwave leakage meets the national standard.
  5. The microwave beef jerking dryer has the function of sterilization. The microwave heating effect, the biological effect has a bactericidal effect. Each microwave equipment is microwave sterilization equipment.
  6. Beef jerky microwave drying equipment can reduce the cost. Compact structure, small floor area, could reduce site cost. Simple operation, PLC automatic control, could save the manpower cost.

Main components of beef jerky microwave drying equipment:

1.The automatic temperature control system

2.Microwave density automatic control system

3.The automatic deviation correction system

4.Automatic alarm system

5.Variable frequency speed control system

6.Material control system

7.Data switching programming system


Application of microwave drying equipment for beef jerky:

It can be used to dry and sterilize fish, dried pork, chicken breast, shredded squid, braised chicken, roast duck, sauce products, shrimp chips, etc. It can also be used for curing and sterilizing cakes, roasted melon seeds, cereals, bean flour processing, and other food industries.

Working principle of beef jerky microwave drying equipment:

Like pet food microwave drying equipment, the principle of microwave drying equipment for beef jerky is that the rapidly changing high-frequency electromagnetic field acts on the water molecules in beef jerky. It will cause the polarity of the water molecules to change and produce the phenomenon of spin movement.

At this time, the field energy of the microwave field is transformed into the heat energy in the medium, and the beef jerky temperature increases, resulting in a series of physical and chemical processes, such as thermalization, to achieve the purpose of microwave heating and drying.


Main technical indexes of beef jerky microwave drying equipment:

Microwave Power30 kilowatt
Power ConsumptionLess than 45 kilowatts


Transmission Speed 

0.5-5 M/min

Output in one shiftEach shift produces 400 kilograms of beef jerky
Energy Consumption 

0.6-0.8 Yuan/kg


Development of beef drying technology:

At first, the sun drying, Kang baking method. Quality of beef jerky is inferior, sanitation condition is poor.

Later, drying beef jerky in steam or electric oven usually. Sanitary conditions were improved, reducing dust and bacterial contamination. But there are still three big problems:

1. Long drying time. After soaking beef jerky, it takes a long time to reach the requirement of 10-12% of the finished product moisture, which limits the production increase.

2. Large energy consumption, high cost, low economic efficiency, waste of energy.

3. Sterilization is not complete, health indicators can not meet the requirements.

Traditional heating provides heat energy to materials through conduction. The surface of beef jerky is first dried and then hardened to form a shell. The external heat is difficult to get in, and the internal moisture is difficult to get out. Therefore, slow drying speed, low efficiency, long cycle, and temperature are not easy to control, directly affecting the drying rate and quality of materials.

Microwave vacuum drying uses microwave energy to heat beef jerky in a vacuum state. In the microwave field, beef jerky absorbs microwave energy and generates heat as a whole. Heat evenly distributed, high utilization rate, water quickly discharged. At the same time, the transfer of microwave energy in the vacuum state will not be affected, there is no loss of energy. The whole drying process is characterized by low temperature, fast speed, and high quality.

The microwave drying equipment of beef jerk has higher controllability, energy-saving 80%, the rate of recovery is almost 100%, like other microwave equipment such as microwave puffing equipment. It can greatly improve the economic benefits of enterprises, It is a modern drying technology with a broad prospect.
