Problems solved by technology

In order to prevent the microwave from leaking into the environment, the length of the suppression section must be more than 2m, so that the space utilization rate of equipment and workshops is low. At the same time, the microwave energy weakened and absorbed by the entire suppression section accounts for about 30% of the output. reduce

Embodiment 1

[0036] Embodiment 1: as Figure 1 to Figure 5 As shown, a microwave thawing equipment includes a bracket 1, a microwave heating device, a microwave generator 24 and a control system, the microwave heating device is fixedly arranged on the bracket 1, and the microwave heating device includes successively connected A material suppression chamber 5, a heating chamber 6 and a discharge suppression chamber 7, the heating chamber 6 is provided with a slot antenna 19, and the communication port between the feed suppression chamber 5 and the heating chamber 6 is provided with a first The inner screen door mechanism 10, the port of the feed suppression chamber 5 far away from the heating chamber 6 is provided with a first outer screen door mechanism 11, the communication port between the discharge suppression chamber 7 and the heating chamber 6 A second inner shield door mechanism 12 is provided, and a second outer shield door mechanism 13 is provided at the port of the discharge suppr...

Embodiment 2

[0067] Embodiment 2: be the preferred embodiment of embodiment 1

[0068] The difference with embodiment 1 is characterized in that:

[0069] Preferably, when the length of the microwave thawing device is 8m, the length of the feed suppression chamber 5 and the discharge suppression chamber 7 is reduced to 1m, the length of the heating chamber 6 is increased to 6m, and the length of the corresponding slot antenna 19 is also 6m, Such as Figure 6 As shown, the number of apertures 1901 provided on the slot antenna 19 is preferably 27. Preferably, the distance d between the centers of two adjacent apertures 1901 is 218.72 mm, the angle α between the apertures 1901 and the horizontal line is 10.5°, and the total number of apertures The length L is 144.8mm, and the width W is 25mm.

[0070] Such as Figure 5 As shown, there is also a supporting cross bar for supporting the entire second connecting section 2 .

[0071] Specifically, the waveguide antenna 19 is a slot antenna, an...

Embodiment 3

[0074] A method of using microwave thawing equipment, said microwave thawing equipment is the microwave thawing equipment described in embodiment 1 or 2, and its using method comprises

[0075] Step 1: Turn on the microwave generator 24, and the microwave generated by the microwave generator is transmitted into the heating cavity 6 through the aperture 1901 on the slot antenna 19;

[0076] Step 2: the control system controls the first outer screen door mechanism 11 to open, the material to be defrosted is input into the feed suppression chamber 5, and the control system controls the first outer screen door mechanism 11 to close;

Abstract

The invention discloses a method for using a microwave thawing device. Step 1: Turn on the microwave generator, and the microwave generated by the microwave generator is transmitted to the heating cavity through the aperture on the slot antenna; Step 2: The control system controls the first outer shielding door The mechanism is opened, the material to be thawed is input into the feed suppression chamber, and the first outer shield door mechanism is closed; Step 3: the control system controls the first inner shield door mechanism and the second inner shield door mechanism to open simultaneously, and the waiting in the feed suppression chamber The thawed material is input to the heating chamber, and the thawed material in the heating chamber is output to the discharge suppression chamber, and the first inner screen door mechanism and the second inner screen door mechanism are closed at the same time; Step 4: The control system controls the second outer screen door mechanism Open, the thawed material is output from the discharge suppression cavity to the outside, and the second outer screen door mechanism is closed; the invention can effectively prevent microwave leakage, and can make microwave thawing more uniform, improve thawing efficiency, and increase energy utilization.

Description

technical field [0001] The invention relates to the technical field of microwave thawing, in particular to a method for using microwave thawing equipment. Background technique [0002] Microwave thawing uses the vibration of polar molecules to produce elastic collisions and friction with surrounding molecules to generate heat. The heating method is generated from the inside of the product material. Using this method to return to temperature and thaw food has low production costs, high efficiency, and no bacterial growth in the product. The advantage of small footprint is unmatched by other process methods. As a flow-through production line, industrial microwave thawing equipment is generally longer and larger, and safety is also more important. [0003] In order to ensure the environmental safety of production personnel, microwave thawing equipment must have a device to suppress microwave leakage. The microwave thawing equipment is mainly divided into three sections: microw...
