Meat Thawing Microwave Equipment
Meat food is rich in nutrients such as water, protein, and fat. It is a good medium for microorganisms, and its high activity of tissue enzymes causes the greatest difficulty in meat preservation; cryopreservation is a good solution to this difficulty. However, frozen meat must be thawed for cooking and eating. Improper thawing can also lead to quality and safety issues.

Meat food is rich in nutrients such as water, protein, and fat. It is a good medium for microorganisms, and its high activity of tissue enzymes causes the greatest difficulty in meat preservation; cryopreservation is a good solution to this difficulty. However, frozen meat must be thawed for cooking and eating. Improper thawing can also lead to quality and safety issues. Uniform and fast, water retention and high safety are the most basic requirements for meat thawing.
Disadvantages of traditional thawing methods:
At present, the common thawing methods for meat mainly use external heating methods such as convection, conduction, or radiation (such as natural air thawing, running water, thawing, hot water, thawing, etc.) and dielectric induction internal heating methods such as low frequency, high frequency or microwave (e.g., microwave thawing). The practice has proved that the ordinary heating method has low thawing efficiency, a large juice loss rate, and an easy introduction of microbial contamination, which is not conducive to food quality and safety. The dielectric induction heating has high requirements on the meat itself and the operating conditions, and the internal thawing is prone to obvious unevenness and local overheating.
Meat microwave thawing machine
Advantages of meat thawing microwave equipment:
- The meat thawing microwave machine has a high degree of automation, no need for pre-processing such as division. It can realize one-key thawing, quick thawing, good effect, strong applicability, and simple method.
- Meat thawing microwave equipment uses spectroscopy technology to monitor the thawing process, which is fast and accurate and solves the problem of discriminating the "thaw endpoint" in the industry.
- Meat thawing microwave equipment has no problems with overheating, oxidation, dry consumption, etc. It better solves problems such as protein denaturation, fat oxidation, and juice loss.
- The advantages of high-voltage electrostatic field and vacuum thawing are fully exerted. The deficiencies of the two can be overcome, the thawing rate is fast, and the effect is good. The degree of automation is high through the spectrum regulation, and one-click thawing can be achieved.
- Low concentration ozone and corona wind generated by a high voltage electrostatic field can effectively kill microorganisms and have high safety.
- Thawing by vacuum and high voltage electrostatic field can accelerate the thawing and reduce the equipment cost and energy consumption required for vacuum thawing.
Meat thawing microwave equipment structure diagram
Working principle of meat thawing microwave equipment:
Step 1: Open box door 1, place the frozen meat on the rotating tray of the pressure sensor 10, and close the box door 1;
Step 2: Start the power supply, the PLC system 13 preset vacuum degree is 93 kPa, the humidity is 80%-85%; the light source 6 is turned on; the pressure sensor reads the frozen product quality; the PLC system 13 controls the motor 12 to drive the pressure sensor 10 to rotate automatically; The CCD camera lens 8 collects spectral information and 3D images of the frozen product; retrieving the spectral image in the database to identify the initial temperature, type, size and shape of the frozen product;
Step 3: The PLC system 13 sets the voltage and time t required for thawing according to the identified frozen product information;
Step 4: The CPU in the PLC system 13 issues an instruction to activate the vacuuming device 16, so that the vacuum in the chamber of the upper chamber reaches 93 kPa, and then the humidifier 4 is opened, the humid steam is introduced, and the humidity thereof reaches 80%-85%. Finally, the high voltage generating device 15 is activated. The high voltage generating device 15 outputs a 15-25 kV voltage to form a high voltage electrostatic field between the negative electrode plate 7 and the positive electrode plate 9. The generated corona wind acts on the frozen product until the thawing ends. Open the normal pressure valve, and after the normal pressure is restored in the upper chamber's cavity, the defrosted meat can be taken out.
