Description

Technical Field

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

[0002] Vacuum thawing equipment can create and maintain a highly negative pressure environment, and 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 and releases heat to achieve 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 the loss of meat juice can also be avoided.

[0003] In the prior art, most vacuum thawing equipment is 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. In order to ensure the negative pressure environment in the vacuum thawing equipment, the vacuum pump needs to be intervened periodically, which leads to increased energy consumption. When the water vapor liquefies on the surface of the meat to form water droplets, it will carry salts, oils, etc. of the meat. In the process of the water droplets falling, impurities will be attached to the inner surface of the cabinet, which will make the subsequent cleaning work more cumbersome. Summary of the invention

[0014] In another aspect, the present invention provides a thawing method of a thawing device for meat food processing, comprising the following steps: Step 1: Open the cabinet door and place the meat to be thawed on the mesh plate on the placement slot. During the meat placement process, the placement slot rotates to allow the meat to be spread flat on all parts of the mesh plate. Step 2: After the meat is placed, the placement slot is rotated so that the placement slot contacts the cover body, so that the cover body and the placement slot can be enclosed to form a sealed space; Step 3: Close the cabinet door, then close and seal the storage box, turn on the switch of the vacuum pump, and extract the gas inside the cabinet when the vacuum pump works. In this process, turn on the switch of the first solenoid valve, so that the gas in the first tube body is extracted, and through the action of the first pressure relief valve, the gas in the second tube body is also extracted, so that the gas in the cabinet, the first tube body and the second tube body is all extracted by the vacuum pump, so that the cabinet, the first tube body and the second tube body are all in a high vacuum state; Step 4: Pour water into the water tank, and keep the water inside the water tank at a relatively low temperature through the temperature control system. Then, the water pump is operated to cooperate with the water injection pipe to inject the water in the water tank into the second seat body at a position below the partition, and then the switch of the third solenoid valve is turned on to allow the water there to enter the second tube body; Step 5: Pour water into the box, turn on the switch of the electric heating system, generate water vapor in the box through the electric heating system, then turn on the switch of the circulation pump. When the circulation pump is working, the water vapor passes through the box and one of the connecting pipes into the first heat exchange pipe, and then enters the circulation pump through the other connecting pipe. The circulation pump then pumps the water vapor into the box through the circulation pipe to realize the circulation of the water vapor. When the water vapor flows through the first heat exchange pipe, the water in the second pipe body is heated. Since the second pipe body is in a highly negative pressure state, low-temperature water vapor will be generated at a lower temperature. Step 6: Turn on the switch of the second solenoid valve, the low-temperature water vapor in the second tube body and the second solenoid valve enters the second connecting seat, 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; Step 7: When the amount of water in the second tube body reaches a certain level, the switch of the third solenoid valve is closed. As the water pump continues to work, the water pressure below the partition continues to rise, and finally enters above the partition through the second pressure relief valve to fill the second heat exchange tube, and flows back to the water tank through the water delivery pipe, so that the low-temperature water circulates in the second heat exchange tube 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 water vapor that has not been liquefied in time enters the first connecting seat through the first connecting pipe, and is then guided to the fins through the reflux pipe. After the water vapor that has not been liquefied in time contacts the low-temperature fins, it liquefies on the surface of the fins, so as 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 subsequent continuous output of low-temperature water vapor; Step 8: The water droplets condensed on the surface of the meat enter the third connecting seat through the third connecting pipe, and then enter the first tube body through the one-way valve and the hose. The liquefied water droplets on the surface of the fins also fall under the first tube body and enter the storage box through the output pipe to achieve the storage of condensed water. Step nine: When cleaning the device, it is still necessary to press the cover body and the placement groove, then increase the power of the electric heating system, and close the second solenoid valve to allow the water in the second tube body to continue to boil, and eventually enter the gap between the first tube body and the second tube body through the first pressure relief valve, and then the high-temperature steam enters the first connecting seat through the reflux pipe, and 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 connecting seat through the third connecting pipe, and then enters between the first tube body and the second tube body through the one-way valve and the hose, so as to use the high-temperature steam to steam clean the cover body and the placement groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention provides a placement groove, a first tube body, an annular seat and a cover body, and rotates the placement groove. Through the spiral placement groove and the cover body, the placement groove can gradually approach the cover body during the 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 condense quickly during the thawing process, thereby ensuring that the space enclosed by the placement groove and the cover body is continuously in a low-pressure state, thereby reducing the intervention frequency of the vacuum pump.

[0016] (2) The present invention can realize vacuum thawing by providing a condensing component, a first connecting component, a second connecting component and a heating component, through which low-power operation of the heating component and a negative pressure environment can be used to generate low-temperature water vapor. During the cleaning process, high-power operation of the heating component can be used to make high-temperature steam flow through the space enclosed by the placement groove and the cover body, thereby realizing high-temperature steam cleaning.

[0017] (3) The cabinet, the placement groove and the cover body provided in the present invention can realize the function of the placement groove and the cover body. During the thawing process, the steam is confined to the space enclosed by the placement groove and the cover body, and the water droplets generated by liquefaction will also be confined in the space, thereby limiting the distribution range of impurities, which is convenient for subsequent cleaning work.

During the meat placement process, the placement slot 305 rotates to allow the meat to be spread flat on all parts of the mesh plate 306. Step 2: After the meat is placed, the placement groove 305 is rotated so that the placement groove 305 is in contact with the cover body 302, so that the cover body 302 and the placement groove 305 can be enclosed to form a sealed space; Step 3: Close the cabinet door 102, then close and seal the storage box 105, turn on the switch of the vacuum pump, and when the vacuum pump is working, extract the gas inside the cabinet 101. In this process, turn on the switch of the first solenoid valve 308, so that the gas in the first tube 301 is extracted, and through the action of the first pressure relief valve 602, the gas in the second tube 601 is also extracted, so that the gas in the cabinet 101, the first tube 301 and the second tube 601 is all extracted by the vacuum pump, so that the cabinet 101, the first tube 301 and the second tube 601 are all in a high vacuum state; Step 4: inject water into the water tank 104, and maintain the water inside the water tank 104 at a relatively low temperature through the temperature control system, and then inject the water in the water tank 104 into the second seat body 702 below the partition 705 through the operation of the water pump and the water injection pipe 202, and then turn on the switch of the third solenoid valve 707, so that the water therein enters the second tube body 601; Step 5: Pour water into the box 401, turn on the switch of the electric heating system, generate water vapor in the box 401 through the electric heating system, then turn on the switch of the circulation pump.

When the water vapor flows through the first heat exchange pipe 603, the water in the second pipe 601 is heated. Since the second pipe 601 is in a highly negative pressure state, low-temperature water vapor will be generated at a relatively low temperature. Step 6: Turn on the switch of the second solenoid valve 506, the low-temperature water vapor pipe 507 in the second tube body 601 and the second solenoid valve 506 enter the second connecting seat 504, and then enter the space enclosed by the cover body 302 and the placement groove 305 through the second connecting pipe 505, and liquefy on the surface of the meat to thaw the meat; Step 7: When the amount of water in the second tube body 601 reaches a certain level, the switch of the third solenoid valve 707 is closed. As the water pump continues to work, the water pressure below the partition 705 continues to rise, and finally enters the top of the partition 705 through the second pressure relief valve 706 to fill the second heat exchange tube 703, and flows back to the water tank 104 through the water delivery pipe 201, so that the low-temperature water circulates in the second heat exchange tube 703 and the water tank 104, thereby making the fin 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 fin 704 through the reflux pipe 503. After the water vapor that has not been liquefied in time contacts the low-temperature fin 704, it is liquefied on the surface of the fin 704, so as 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 subsequent continuous output of low-temperature water vapor; Step 8: 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 fin 704 also fall below the first tube body 301 and enter the storage box 105 through the output pipe 307, so that the condensed water is stored; Step nine: When cleaning the device, it is still necessary to contact the cover body 302 and the placement groove 305, then increase the power of the electric heating system, and close the second solenoid valve 506 to allow the water in the second tube body 601 to continue to boil, and finally enter the gap between the first tube body 301 and the second tube body 601 through the first pressure relief valve 602, and then the high-temperature steam enters the first connecting seat 501 through the reflux 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 connecting seat 508 through the third connecting pipe 509, and then enters between the first tube body 301 and the second tube body 601 through the one-way valve 511 and the hose 510, so as to steam clean the cover body 302 and the placement groove 305 with high-temperature steam.
