Description

Technical Field

[0001] The present invention relates to the technical field of vacuum thawing equipment, and in particular to a thawing device and a thawing method for meat food processing. Background Art

[0002] Vacuum thawing equipment can create and maintain a highly negative pressure environment, and at the same time use the highly negative pressure environment to lower the boiling point of water to generate low-temperature water vapor. The low-temperature water vapor liquefies on the surface of the meat to release heat, realizing the thawing of the meat. Due to the highly negative pressure environment, the degree of bacterial reproduction during the thawing process can be effectively reduced, and at the same time, the loss of meat juice can be avoided.

[0003] In the prior art, in most vacuum thawing equipment, it will be filled with low-temperature water vapor to ensure sufficient contact between the meat and the low-temperature water vapor. However, during this process, the air pressure in the vacuum thawing equipment will also rise accordingly. In order to ensure the negative pressure environment in the vacuum thawing equipment, the vacuum pump needs to intervene periodically, resulting in increased energy consumption. When the water vapor liquefies on the surface of the meat to form water droplets, it will carry salts, oils and fats of the meat, etc. During the process of the water droplets dripping, it will cause impurities to adhere to the inner surface of the cabinet, and thus the subsequent cleaning work is more cumbersome.

[0049] An output pipe communicating with the storage box and communicating with the bottom of the first pipe body.

[0050] On the other hand, the present invention provides a thawing method for a thawing device for processing meat products, including the following steps:

[0051] Step 1: Open the cabinet door, place the meat to be thawed on the mesh plate on the placement groove. During the placement of the meat, cooperate with the rotation of the placement groove so that the meat can be laid flat everywhere on the mesh plate;

[0052] Step 2: After the meat is placed, rotate the placement groove so that the placement groove abuts against the cover body, and then the cover body and the placement groove can enclose a sealed space;

[0053] Step 3: Close the cabinet door, then close and seal the storage box, turn on the switch of the vacuum pump. When the vacuum pump works, the gas inside the cabinet body is pumped out. During this process, turn on the switch of the first electromagnetic valve so that the gas in the first pipe body is pumped out. Through the action of the first pressure relief valve, the gas in the second pipe body is also pumped out, so as to realize that the gas in the cabinet body, the first pipe body and the second pipe body is pumped out by the vacuum pump, so that the inside of the cabinet body, the first pipe body and the second pipe body are all in a highly vacuum state;

[0054] Step 4: Inject water into the water tank, and through the temperature control system, keep the water inside the water tank at a lower temperature. Then, through the operation of the water pump, cooperate with the water injection pipe to inject the water in the water tank into the second seat body at the position below the partition board, and then turn on the switch of the third electromagnetic valve so that the water at this position enters the second pipe body;

[0055] Step 5: Inject water into the box body, turn on the switch of the electric heating system, and generate water vapor in the box body through the electric heating system. Then turn on the switch of the circulation pump. When the circulation pump works, the water vapor enters the first heat exchange pipe through the box body and one of the connecting pipes, and then enters the circulation pump through the other connecting pipe. The circulation pump then pumps the water vapor through the circulation pipe back into the box body to realize the circulation of the water vapor. When the water vapor flows through the first heat exchange pipe, it heats the water in the second pipe body. Since the inside of the second pipe body is in a highly negative pressure state, low-temperature water vapor will be generated at a lower temperature;

[0056] Step 6: Turn on the switch of the second electromagnetic valve. The low-temperature water vapor in the second pipe body enters the second communication seat through the steam pipe and the second electromagnetic valve, and then enters the space enclosed by the cover body and the placement groove through the second connecting pipe, and liquefies on the surface of the meat to thaw the meat;

[0057] Step 7: When the water volume in the second pipe body reaches a certain level, turn off the switch of the third solenoid valve. As the water pump continues to operate, the water pressure below the partition plate continuously rises and finally enters above the partition plate through the second pressure relief valve to fill the second heat exchange pipe and then flows back into the water tank through the water delivery pipe, so as to realize the circulation of low-temperature water in the second heat exchange pipe and the water tank, thereby making the fins at a lower temperature. In the space enclosed by the cover body and the placement groove, the unliquefied water vapor enters the first communication seat through the first connecting pipe and is then guided to the fins through the return pipe. After the unliquefied water vapor contacts the low-temperature fins, it liquefies on the surface of the fins to ensure that the space enclosed by the cover body and the placement groove is always in a highly negative pressure environment, thereby ensuring the continuous output of subsequent low-temperature water vapor.

[0058] Step 8: The water droplets condensed on the surface of the meat enter the third communication seat through the third connecting pipe, then enter the first pipe body through the one-way valve and the hose. The water droplets liquefied on the surface of the fins also fall below the first pipe body and enter the storage tank through the output pipe to realize the storage of condensed water.

[0059] Step 9: When cleaning this device, still need to make the cover body and the placement groove contact each other, then increase the power of the electric heating system and turn off the second solenoid valve to make the water in the second pipe body boil continuously and finally enter the gap between the first pipe body and the second pipe body through the first pressure relief valve. Then the high-temperature steam enters the first communication seat through the return pipe, then enters the space enclosed by the cover body and the placement groove through the first connecting pipe. After the high-temperature steam flows through the space enclosed by the cover body and the placement groove, it enters the third communication seat through the third connecting pipe, then enters between the first pipe body and the second pipe body through the one-way valve and the hose to steam-clean the cover body and the placement groove with high-temperature steam.

[0060] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0061] (1) By providing the placement groove, the first pipe body, the annular seat and the cover body, rotating the placement groove, through the spiral placement groove and the cover body, the placement groove can gradually approach the cover body during rotation and finally contact the cover body, so that the placement groove and the cover body can enclose a sealed space, thereby ensuring that the steam can fully contact the meat and quickly condense during the thawing process, and further ensuring that the space enclosed by the placement groove and the cover body is continuously in a low-pressure state to reduce the intervention frequency of the vacuum pump.

[0062] (2) Through the condensation component, the first communication component, the second communication component, and the heating component provided in the present invention, during the thawing process, through the low-power operation of the heating component and in cooperation with the negative pressure environment, low-temperature water vapor can be generated for vacuum thawing work. During the cleaning process, through the high-power operation of the heating component, high-temperature steam flows through the space enclosed by the placement tank and the cover, thereby realizing the high-temperature steam cleaning work.

[0063] (3) Through the cabinet body, the placement tank, and the cover provided in the present invention, during the thawing process, the steam can be restricted in the space enclosed by the placement tank and the cover through the action of the placement tank and the cover. Furthermore, the water droplets generated by liquefaction will also be restricted in this space, thereby limiting the distribution range of impurities to facilitate subsequent cleaning work.

Subsequently, through the operation of the water pump, cooperate with the water injection pipe 202 to inject the water in the water tank 104 into the position below the partition plate 705 in the second seat body 702, and then turn on the switch of the third solenoid valve 707 so that the water at this place enters the second pipe body 601;

[0139] Step Five: Fill the box body 401 with water, turn on the switch of the electric heating system, generate water vapor in the box body 401 through the electric heating system, then turn on the switch of the circulation pump. When the circulation pump works, the water vapor enters the first heat exchange tube 603 through the box body 401 and one of the connecting pipes 404, and then enters the circulation pump through the other connecting pipe 404. The circulation pump then pumps the water vapor into the box body 401 through the circulation pipe 403 to realize the circulation of the water vapor. When the water vapor flows through the first heat exchange tube 603, it heats the water in the second tube body 601. Since the inside of the second tube body 601 is in a highly negative pressure state, low-temperature water vapor will be generated at a relatively low temperature.

[0140] Step Six: Turn on the switch of the second solenoid valve 506. The low-temperature water vapor in the second tube body 601 enters the second connecting seat 504 through the steam pipe 507 and the second solenoid valve 506, and then enters the space enclosed by the cover body 302 and the placement groove 305 through the second connecting pipe 505, and liquefies on the surface of the meat to thaw the meat.

[0141] Step Seven: When the water volume in the second tube body 601 reaches a certain level, turn off the switch of the third solenoid valve 707. As the water pump continues to work, the water pressure below the partition 705 continues to rise and finally enters above the partition 705 through the second pressure relief valve 706 to fill the second heat exchange tube 703, and then flows back into the water tank 104 through the water delivery pipe 201 to realize the circulation of the low-temperature water in the second heat exchange tube 703 and the water tank 104, thereby making the fins 704 at a relatively low temperature. In the space enclosed by the cover body 302 and the placement groove 305, the water vapor that has not been liquefied in time enters the first connecting seat 501 through the first connecting pipe 502, and is then guided to the fins 704 through the return pipe 503. After the water vapor that has not been liquefied in time contacts the low-temperature fins 704, it liquefies on the surface of the fins 704 to ensure that the space enclosed by the cover body 302 and the placement groove 305 is always in a highly negative pressure environment, thereby ensuring the continuous output of subsequent low-temperature water vapor.

[0142] Step Eight: The water droplets condensed on the surface of the meat enter the third connecting seat 508 through the third connecting pipe 509, and then enter the first tube body 301 through the one-way valve 511 and the hose 510. The water droplets liquefied on the surface of the fins 704 also fall below the first tube body 301 and enter the storage tank 105 through the output pipe 307 to realize the storage of the condensed water.

[0143] Step Nine: When cleaning this device, the cover body 302 still needs to be in contact with the placement groove 305. Subsequently, increase the power of the electric heating system and close the second solenoid valve 506 to make the water in the second pipe body 601 boil continuously. And finally, it enters the gap between the first pipe body 301 and the second pipe body 601 through the first pressure relief valve 602. Then, the high-temperature steam enters the first communication seat 501 through the return pipe 503, and then enters the space enclosed by the cover body 302 and the placement groove 305 through the first connecting pipe 502. After the high-temperature steam flows through the space enclosed by the cover body 302 and the placement groove 305, it enters the third communication seat 508 through the third connecting pipe 509, and then enters between the first pipe body 301 and the second pipe body 601 through the one-way valve 511 and the hose 510, so as to perform steam cleaning on the cover body 302 and the placement groove 305 through the high-temperature steam.
