Description

Technical Field

[0001] This utility model relates to the field of steam thawing technology, and in particular to a steam thawing device. Background Technology

[0002] Steam thawing equipment is a device that uses high-temperature steam as a heat source to quickly thaw frozen food, meat, or industrial materials. By directly contacting or indirectly applying steam to the surface of frozen items, the high latent heat of steam is used to quickly transfer heat, causing the ice crystals in the materials to melt rapidly. At the same time, it can reduce moisture loss and nutrient loss during the thawing process. Compared with natural thawing or water thawing, it is more efficient and can prevent material deterioration caused by local overheating through a temperature control system. It is widely used in food processing, catering, and some industrial production fields.

[0003] Currently, most methods for steam thawing frozen materials involve placing the frozen materials on racks inside a thawing chamber, sealing it, and then starting a steam pump to deliver steam into the chamber for static thawing. The thawed water is then discharged. However, the direct discharge of condensate and the reliance on a continuous supply of fresh tap water result in significant water waste. Furthermore, the low temperature of fresh tap water, requiring heating from room temperature to produce steam, leads to high energy costs. Static thawing also causes uneven heating of the material surface, resulting in unthawed, low-temperature dead zones. This necessitates extending the overall thawing time and reducing thawing efficiency.

[0004] Therefore, it is necessary to provide a new steam thawing device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a steam defrosting device.

[0006] The steam defrosting device provided by this utility model includes: a support plate, a defrosting chamber installed on the inner wall of the support plate, a switch door rotatably connected to the front inner wall of the defrosting chamber, a viewing window fixedly connected to the top inner wall of the switch door, a control panel installed at the bottom front of the switch door, sensors on both the left and right sides of the inner wall of the defrosting chamber, a support frame installed on the inner wall of the defrosting chamber, a fitting groove at the bottom of the inner wall of the defrosting chamber, an activated carbon plate fitted into the inner wall of the fitting groove, a water tank fixedly connected to the bottom of the defrosting chamber, a through hole between the defrosting chamber and the water tank, and a fixed bottom of the water tank.

An air extraction head is fixedly connected to the right side of the inner wall of the water tank, and a filter plate is installed inside the air extraction head. A conveying assembly is installed on the right side of the top of the support plate. A steam regulating valve is installed on the top of the thawing box, and a steam head is fixedly connected to the output end of the steam regulating valve. A fixing ring is fixedly connected to the top of the support frame, and a carrying rack is rotatably connected to the inner wall of the top of the fixing ring. A connecting column is fixedly connected to the inner wall of the axis of the carrying rack, and a semi-circular water filter rack is fixedly connected to the bottom end of the connecting column. A drive assembly is installed on the outside of the carrying rack.

[0007] Preferably, the conveying assembly includes a steam pump, the bottom end of which is fixedly connected to the top right side of the support plate, an air extraction pipe is fixedly connected to the inner wall of the top right side of the water tank, and a transmission pipe is fixedly connected to the input end of the steam regulating valve.

[0008] Preferably, the drive assembly includes a rack ring, the inner ring wall of which is fixedly connected to the outer ring of the shelf, a receiving block is fixedly connected to the rear side of the fixed ring and a gear is rotatably connected to the inner wall of the fixed ring, a transmission rod is rotatably connected to the rear inner wall of the top of the defrosting box, and a servo motor is installed on the rear side of the top of the defrosting box.

[0009] Preferably, the two sensors are a temperature sensor and a humidity sensor, and a drain pipe is installed on the left side of the water tank.

[0010] Preferably, the right end of the suction head is fixedly connected to the left end of the suction pipe.

[0011] Preferably, the end of the extraction pipe furthest from the extraction head is fixedly connected to the input end of the steam pump, and the end of the transmission pipe furthest from the steam regulating valve is fixedly connected to the output end of the steam pump.

[0012] Preferably, the rack ring and the gear are meshed, the drive end of the servo motor is fixedly connected to the top of the transmission rod, and the bottom end of the transmission rod is fixedly connected to the inner wall of the gear shaft.

[0013] Compared with related technologies, the steam defrosting device provided by this utility model has the following beneficial effects: This invention uses a servo motor to drive a transmission rod to rotate, which in turn drives a gear to rotate, which in turn drives a rack ring to rotate, which in turn drives a carrier frame to rotate, which in turn drives a connecting column to rotate, and the connecting column drives a semi-circular filter frame to rotate. This causes the frozen material placed on the carrier frame to rotate, allowing all parts of the material to come into more full and even contact with steam. This avoids severely uneven heating of the material surface during static thawing, reduces unthawed low-temperature dead zones, improves thawing efficiency, and eliminates the need to excessively extend the thawing time.

[0014] This invention utilizes a heating wire within a jacketed sleeve to heat the water in the water tank, generating steam. Simultaneously, the condensate produced during thawing flows back into the water tank through a perforation between the thawing chamber and the water tank, and is filtered by an activated carbon plate, achieving condensate recycling and reducing water waste. Moreover, compared to continuously supplying steam production with fresh tap water, the recycled condensate has a relatively higher temperature, resulting in lower energy consumption when reheating for steam production, thus reducing energy costs.

[0019] The conveying assembly includes a steam pump 16, the bottom of which is fixedly connected to the top right side of the support plate 1, providing power for steam extraction and delivery. A suction pipe 15 is fixedly connected to the inner wall of the top right side of the water tank 10. The right end of the suction head 13 is fixedly connected to the left end of the suction pipe 15. The end of the suction pipe 15 away from the suction head 13 is fixedly connected to the input end of the steam pump 16, facilitating the steam pump 16 to extract steam from the water tank 10. A transmission pipe 17 is fixedly connected to the input end of the steam regulating valve 18. The end of the transmission pipe 17 away from the steam regulating valve 18 is fixedly connected to the output end of the steam pump 16 for transmitting steam.

[0020] A steam regulating valve 18 is installed at the top of the defrosting chamber 2, which can regulate the steam flow rate, etc. A steam head is fixedly connected to the output end of the steam regulating valve 18 for delivering steam into the defrosting chamber 2. A fixing ring 19 is fixedly connected to the top of the support frame 7. A carrying rack 20 is rotatably connected to the inner wall of the top of the fixing ring 19.

When the rack 20 rotates, it will drive the connecting column 21 to rotate together. The rotation of the connecting column 21 will then drive the semi-circular water filter rack 22 to rotate. In this way, the frozen material placed on the rack 20 will rotate accordingly, so that all parts of the material can come into more full and even contact with the steam that subsequently enters the defrosting chamber 2, laying the foundation for uniform defrosting. At the same time, the heating wire 12 inside the jacket 11 starts to work, heating the water inside the water tank 10. The water generates steam after being heated. Then, the steam pump 16 starts, drawing the steam generated in the water tank 10 through the suction pipe 15 and the suction head 13. The drawn steam is transported to the steam regulating valve 18 through the transmission pipe 17. After the steam regulating valve 18 regulates the steam flow rate, the steam is transported to the inside of the thawing box 2 through the steam head. The steam diffuses in the thawing box 2 and comes into full contact with the rotating frozen material to carry out the thawing operation. During the thawing process, two sensors 6 on the left and right sides of the inner wall of the thawing chamber 2, namely a temperature sensor and a humidity sensor, continuously monitor the temperature and humidity inside the thawing chamber 2 so as to adjust the relevant operating parameters in a timely manner according to the actual situation to ensure the thawing effect. The condensate generated during the thawing process will flow into the water tank 10 through the through hole opened between the thawing chamber 2 and the water tank 10 and the filter of the activated carbon plate 9 to realize the recovery of condensate. When the thawing operation is completed, the operator can drain the liquid through the drain pipe.
