[0002] Frozen meat and other foods need to be thawed using thawing equipment before processing and using sausages. Commonly used thawing equipment is low-temperature and high-humidity thawing machine, which is mainly used for continuous thawing of frozen meat. The thawing body of low-temperature and high-humidity thawing machine is low-temperature and high-humidity steam. The steam blows the thawed products to form a uniform airflow organization on the surface of the products. The thawing temperature and time are automatically controlled in stages by the PLC system to achieve thawing. The low-temperature and high-humidity thawing machine mainly includes a thawing chamber and a thawing cart. The thawing cart is equipped with a multi-layer grate-shaped tray. When thawing, the product is placed on the grate and the thawing cart is pushed into the thawing chamber;

[0003] When the existing low-temperature and high-humidity thawing machine is thawing, since the density of water vapor is lower than that of air, the water vapor in the air will inevitably rise, causing a large amount of steam to gather on the inner top wall of the thawing chamber. The steam is easily discharged due to pressure relief, resulting in a lot of steam not being utilized, thereby causing a waste of resources.

[0004] Therefore, it is necessary to provide a new low-temperature and high-humidity thawing chamber to solve the above-mentioned technical problems. Utility Model Content

[0009] Preferably, a fixed ring is sleeved on the vertical tube of the L-shaped connecting tube, and two vertically arranged guide rods are fixedly installed on the fixed ring. Limiting rings are fixedly installed on both sides of the vertical tube of the L-shaped tube near the bottom, and the two guide rods respectively pass through the two limiting rings and are slidably connected to the limiting rings.

[0010] Preferably, an adjustment component for adjusting the height of the duckbill nozzle is installed on the wall on the same side of the thawing room and the reflux component.

[0011] Preferably, the adjustment assembly includes a reciprocating screw, which is rotatably mounted on the inner wall of the thawing room through a mounting frame, and a driving motor for driving the reciprocating screw to rotate is also mounted on the mounting frame, a threaded sleeve with a threaded connection is provided on the reciprocating screw, and a mounting plate is fixedly mounted on the threaded sleeve, a number of equidistantly distributed guide rings are fixedly mounted on the mounting plate, and the guide rings are respectively fixedly mounted on the L-shaped connecting pipe in the alignment reflux assembly.

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0026] See also Figures 1 to 5 The embodiment of the utility model provides a low-temperature and high-humidity thawing chamber, which includes: a thawing room 1, a reflux component 4 and a regulating component 5.

[0027] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 A plurality of evenly distributed steam spray pipes 2 are fixedly installed on the front and rear inner walls of the thawing room 1, and a circulating fan 3 is installed on the inner top wall of the thawing room 1;

[0028] A sewage collecting box 6 is fixedly connected to the bottom of the thawing room 1, and a plurality of conical pedals 7 are laid between the sewage collecting box 6 and the thawing room 1. An inverted trapezoidal cavity 7a for draining sewage is reserved between adjacent conical pedals 7. A revolving door 8 is installed on the front wall of the thawing room 1.

[0029] It should be noted that: the steam nozzle 2 is connected to a steam system (a steam heating system is a heating system, which uses water as a heating medium, carries heat from a heat source in the form of steam, and is connected through a heat network. This is a prior art and will not be described in detail here) for supplying steam to the thawing room 1, so that the frozen products (such as fish, meat, etc.) in the thawing room 1 can be steam-thawed through the steam nozzle 2, and by arranging a conical pedal 7 at the bottom of the thawing room 1, it is convenient to drain water through the inverted trapezoidal cavity 7a, so that workers are not easy to slip when moving in the thawing room 1, and it is convenient for workers to walk;

[0030] Among them, a bridge plate 9 is installed on the front end surface of the sewage collection box 6, which is convenient for the staff to enter and exit the thawing room 1 from the bridge plate 9.

[0031] In the embodiments of the present invention, please refer to Figure 2 , Figure 3 and Figure 4 On both sides of the thawing room 1, there are installed several groups of equidistantly distributed reflux components 4, through which the rising steam is guided to the bottom of the thawing room 1 for thawing the frozen products;

[0032] The reflux assembly 4 includes an L-shaped tube 41, a return steam pipe 42 is fixedly installed on the horizontal tube of the L-shaped tube 41, and a draft fan 43 is embedded in the return steam pipe 42, the vertical tube of the L-shaped tube 41 is fixedly installed on the inner wall of the thawing room 1 through a tube clamp, and an elastic corrugated hose 44 is fixedly connected to the bottom of the vertical tube of the L-shaped tube 41, an L-shaped connecting tube 45 is fixedly connected to the bottom of the elastic corrugated hose 44, and a duckbill nozzle 46 is fixedly installed on the horizontal tube of the L-shaped connecting tube 45.

[0033] It should be noted that: when the steam spray pipe 2 thaws the frozen products in the thawing room 1, the steam in the air will rise because the steam density is lower than that of the air. At this time, the induced draft fan 43 is turned on to suck the steam gathered at the top of the thawing room 1 into the L-shaped tube 41. Since the L-shaped tube 41 guides the steam to the elastic pleated hose 44 and the L-shaped connecting tube 45, and finally sprays the duckbill nozzle 46 into the thawing room 1, the floating steam can be sucked back and the remaining heat can be used to thaw the frozen products, thereby greatly improving the utilization rate of the steam.

[0034] Among them, a fixedly connected fixing ring 47 is sleeved on the vertical tube of the L-shaped connecting tube 45, and two vertically arranged guide rods 48 are fixedly installed on the fixing ring 47. Limiting rings 49 are fixedly installed on both sides of the vertical tube of the L-shaped tube 41 near the bottom. The two guide rods 48 pass through the two limiting rings 49 respectively and are slidably connected to the limiting rings 49, so that when the adjustment component 5 adjusts the height of the duckbill nozzle 46, the guide rods 48 can improve the stability of the duckbill nozzle 46 and avoid the problem of sideways rotation of the duckbill nozzle 46;

[0035] In the embodiments of the present invention, please refer to Figure 3 and Figure 5 An adjusting component 5 for adjusting the height of the duckbill nozzle 46 is installed on the wall on the same side of the thawing room 1 and the reflux component 4, and the adjusting component 5 includes a reciprocating screw 51, and the reciprocating screw 51 is rotatably installed on the inner wall of the thawing room 1 through a mounting frame, and a driving motor 52 for driving the reciprocating screw 51 to rotate is also installed on the mounting frame, and a threaded sleeve 53 with a threaded connection is sleeved on the reciprocating screw 51, and a mounting plate 54 is fixedly installed on the threaded sleeve 53, and a plurality of equidistantly distributed guide rings 55 are fixedly installed on the mounting plate 54, and a plurality of the guide rings 55 are respectively fixedly installed on the L-shaped connecting pipe 45 in the alignment reflux component 4.

[0036] It should be noted that: turning on the drive motor 52 drives the reciprocating screw 51 to rotate, so that the threaded sleeve 53 slides back and forth along the reciprocating screw 51, thereby driving the height of the L-shaped connecting pipe 45 in each reflux component 4 to compress or stretch the elastic pleated hose 44, so that the duckbill nozzle 46 on the L-shaped connecting pipe 45 can continuously adjust the height, so that it can steam thaw different layers of the frozen product, greatly improving the thawing rate.

[0037] The working principle of the low temperature and high humidity thawing chamber provided by the utility model is as follows:

[0038] The steam nozzle 2 is connected to a steam system for supplying steam to the thawing room 1, so that the frozen products (such as meat, etc.) in the thawing room 1 can be thawed by steam through the steam nozzle 2. By arranging a conical pedal 7 at the bottom of the thawing room 1, it is convenient to drain water through the inverted trapezoidal cavity 7a, so that workers are not prone to slipping when moving in the thawing room 1, and it is convenient for workers to walk. When the steam nozzle 2 thaws the frozen products in the thawing room 1, since the steam density is lower than that of air, the steam in the air will rise. At this time, the induced draft fan 43 is turned on to suck the steam gathered at the top of the thawing room 1 into the L-shaped tube 41. Since the L-shaped tube 41 guides the steam to the elastic pleated soft The steam in the tube 44 and the L-shaped connecting tube 45 is finally sprayed into the thawing room 1 by the duckbill nozzle 46, so the floating steam can be sucked back and the frozen products can be thawed by the remaining heat, thereby greatly improving the utilization rate of the steam. The driving motor 52 is turned on to drive the reciprocating screw 51 to rotate, so that the threaded sleeve 53 slides back and forth along the reciprocating screw 51, thereby driving the height of the L-shaped connecting tube 45 in each reflux component 4 to compress or stretch the elastic pleated hose 44, so that the duckbill nozzle 46 on the L-shaped connecting tube 45 can continuously adjust the height, so that it can steam thaw different layers of the frozen products, greatly improving the thawing rate. The bridge plate 9 can facilitate the pushing of the shelf of the frozen product. The shelf is common and varies according to the actual situation. It is not protected in this case, so it will not be described in detail.

[0039] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0040] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
