Description

Technical Field

[0001] The utility model relates to quick-freezing equipment, in particular to a tunnel quick-freezing device with an improved mesh belt. Background Art

[0002] The existing tunnel quick-freezing device adopts all-metal conveyor mesh belts at each layer. During the low-temperature freezing process, the food is frozen to the metal mesh surface, making it difficult for the frozen food to separate from the metal mesh belt, resulting in poor delivery of the frozen food. Alternatively, the frozen food is torn and separated from the metal mesh surface, causing damage to the mesh surface and affecting the service life of the metal mesh belt. Summary of the invention

[0003] The utility model aims to propose an improved mesh-belt tunnel quick-freezing device to solve the problem in the background technology that each layer of the tunnel quick-freezing device adopts a full-metal conveyor mesh belt. During the low-temperature freezing process, the food is frozen to the metal mesh surface, making it difficult for the frozen food to separate from the metal mesh belt, resulting in poor material removal and transportation of the frozen food, or the frozen food is torn and hard-separated from the metal mesh surface, causing the mesh surface to be damaged, thereby affecting the service life of the metal mesh belt.

[0004] The technical solution adopted to solve the technical problem is: an improved mesh belt tunnel quick-freezing device, an insulation box and an insulation warehouse door are arranged on the bottom frame, a feeding frame and a discharging frame are arranged at both ends of the insulation box, an inner cavity frame is arranged inside the insulation box, an evaporator and a fan are arranged at adjacent positions of the inner cavity frame, a wind shield baffle is arranged on the top between the evaporator and the inner cavity frame and on the top of the inner cavity frame, a transmission shaft is arranged on the feeding frame, the discharging frame and the inner cavity frame to drive each layer of mesh belt to run to form a conveying rotation, and a receiving plate is arranged at the discharging end of each layer of mesh belt in the insulation box; it is characterized in that: the top layer of the above-mentioned mesh belt is arranged as a plastic mesh belt, and the remaining layers of mesh belt are arranged as metal mesh belts.

[0005] Compared with the background technology, the beneficial effect of the utility model is as follows: due to the adoption of the above technical scheme, the top layer is set as a plastic mesh belt. Since the physical properties of the plastic mesh belt are obviously different from those of the metal mesh belt, the possibility of food freezing on the mesh surface is significantly reduced, and the food can be removed smoothly. After the food is frozen by the topmost plastic mesh belt, a harder ice film layer is formed on the surface of the food, which is smoothly transferred to the next layer of metal mesh belt through the receiving plate. It is not easy to freeze with the remaining multi-layer metal mesh belt surfaces, thereby extending the service life of the multi-layer metal mesh belt. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Example: Reference Figure 1 , Figure 2 A tunnel quick-freezing device with an improved mesh belt, a heat preservation box 7 and a heat preservation door 6 are arranged on the bottom frame 8, a feeding frame 2 and a discharging frame 10 are arranged at both ends of the heat preservation box 7, an inner cavity frame 3 is arranged inside the heat preservation box 7, an evaporator 12 and a fan 11 are arranged at adjacent positions of the inner cavity frame 3, a wind shield baffle 13 is arranged on the top between the evaporator 12 and the inner cavity frame 3 and on the top of the inner cavity frame 3, a transmission shaft 1 is arranged on the feeding frame 2, the discharging frame 10 and the inner cavity frame 3 to drive each layer of mesh belt to run to form a conveying rotation, and a receiving plate 9 is arranged at the discharging end of each layer of mesh belt in the heat preservation box 7; it is characterized in that: the top layer of the above-mentioned mesh belt is set as a plastic mesh belt 4, and the remaining mesh belts are set as metal mesh belts 5.

[0009] When the above-mentioned quick-freezing device is in operation, the food is driven by the transmission shaft 1 through the feeding frame 2 to drive the top plastic mesh belt 4 and the remaining multi-layer metal mesh belts 5, and enters the insulation box 7 for freezing. The cold air flows through the fan 11 and the evaporator 12 to strengthen the output, and fully exchanges heat with the food on the plastic conveyor belt 4 and the multi-layer metal mesh belt 5. First, a harder ice film layer is gradually formed on the surface of the food on the plastic conveyor belt 4, and then smoothly transitions to the next layer of the multi-layer metal mesh belt 5 through the receiving plate 9, and is not easy to freeze with the mesh surface of the multi-layer metal mesh belt 5. After deep freezing, the food is transported out of the insulation box 7 by the multi-layer metal mesh belt 5, and is shipped on the discharging frame 10. The cold air after the heat exchange with the food flows back to the fan 11 through the space channel between the insulation box 7 and the wind shield 13, and repeats this process.
