Description

Technical Field

[0001] The utility model relates to the technical field of quick-freezing machines, in particular to a novel double-refrigeration tunnel-type quick-freezing machine. Background Art

[0002] Quick freezer is a highly efficient freezing equipment that can freeze a large number of products in a short time. In a short time, the center temperature of the quick-frozen items can be frozen to -18°, and they will quickly pass through the ice crystal production belt within 30 minutes to reduce the loss of nutrients and keep the original flavor. It can effectively and economically freeze a variety of products placed in the quick freezer, such as meat, fish, shrimp, meatballs, vegetables, prepared foods, dairy products, etc. in various shapes.

[0003] For example, a Chinese patent (Announcement No.: CN211903451 U) discloses a tunnel-type double-mesh belt quick-freezing machine with forced cooling and double-side air distribution. The problems to be solved are: low air flow circulation utilization rate, low quick freezing efficiency, and long food freezing time when quick-freezing food in traditional quick-freezing machines; difficulty in distributing goods due to excessive width of the mesh belt; and mismatch with the mesh belt of automatic transmission equipment. The key points of the technical solution adopted are: double feeding transmission mechanisms and corresponding double discharging transmission mechanisms are arranged at both ends of the insulation box body, and their transmission shafts respectively drive their respective double conveying mesh belts to form a rotating circuit for driving the transportation of frozen products. An inner cavity frame is arranged inside the insulation box body, a centrifugal fan is arranged in the middle of the inner cavity frame, and lower and upper air distribution plates with evenly distributed conical edge through holes are arranged on both sides of the inner cavity frame to quickly exchange heat and cold for the frozen products on the mesh belt between the lower and upper air distribution plates. Heat exchangers are arranged on both sides of the upper part of the inner cavity frame to exchange heat and cold for the air in the cavity, which is suitable for the rapid freezing of various frozen products.

[0004] The above-mentioned tunnel-type double-mesh belt quick-freezer with forced cooling and double-sided air distribution still has certain shortcomings. Through the action of the tapered through holes of the upper and lower air distribution plates, the high-speed cold air flow is strengthened into a high-speed jet-type cold air flow. The frozen food is transported along the conveyor belts on both sides of the frame, and the upper and lower air distribution plates at the upper and lower positions of the conveyor belts continuously spray out high-speed jet-type cold air flows, which continuously and vertically freeze the frozen products quickly. However, during the use of the quick-freezer, since the size of the inlet and outlet ports of the quick-freezer is fixed and the size of the inlet and outlet ports cannot be adjusted, the loss of cold air occurs, which not only has a poor quick-freezing effect on the items, but the quick-freezing machine can only quick-freeze one side of the items, and the quick-freezing efficiency of the items is low, affecting the working efficiency of the quick-freezer. Therefore, the present application proposes a new double-refrigeration tunnel-type quick-freezer to solve the above-mentioned problems. Utility Model Content

When the object is small, the baffle 408 can reduce the cold air flowing out of the through hole 5, thereby improving the cooling effect.

[0028] See also Figure 4 In order to improve the cooling effect, the cooling mechanism 6 in this embodiment includes two tube bodies 608 fixed between the front and rear sides of the inner cavity of the body 1, and multiple air outlet ducts 609 are fixed on the opposite sides of the two tube bodies 608. The cooling mechanism 6 also includes a box body 601 fixed to the upper surface of the inner cavity of the body 1, and a partition 602 is fixed to the inner cavity wall of the box body 601. A cooler 603 is fixed on the lower surface of the inner cavity of the box body 601 for cooling the inhaled air and discharging it. Two fans 605 are fixed on the upper surface of the upper end tube body 608, and a first air duct 604 is fixed to the input end of the fan 605, and a second air duct 606 is fixed to the output end of the fan 605. A third air duct 607 is fixed to the opposite side of the two second air ducts 606.

[0030] In addition, a first air inlet is provided on the upper surface of the box body 601 and the body 1, and a connecting hole is provided on the upper surface of the partition 602 to facilitate air to enter the cooler 603 for cooling. Second air inlets are provided on the left and right sides of the box body 601 to facilitate the used air in the body 1 to enter the box body 601 for recycling, thereby reducing energy consumption. Filters are fixed inside the first air inlet and the second air inlet to prevent dust from entering the box body 601.

[0031] It should be noted that the cooler 603 is a device for cooling air in the prior art, and its working principle will not be described in detail herein.

[0032] In the cooling mechanism 6 of this embodiment, the fan 605 sucks external air into the box body 601 through the first air inlet hole, and enters the cooler 603 through the connecting hole. The air is cooled by the cooler 603, and the cooled air enters the second air duct 606 through the first air duct 604.

[0033] The working principle of the above embodiment is:

[0034] (1) When the object conveyed by the conveyor 3 is of large volume, the dual-axis motor 402 is started. The dual-axis motor 402 drives the rotating rod 403 and the first bevel gear 404 to rotate together, and drives the second bevel gear 405 and the threaded rod 406 to rotate together through the first bevel gear 404. The two threaded rods 406 rotate simultaneously, driving the rod sleeve 407 and the baffle 408 to move together. The baffle 408 drives the slider to slide on the outer surface of the slider, thereby increasing the stability of the baffle 408 when moving. By changing the position of the baffle 408, the aperture of the through hole 5 is adjusted to facilitate the quick freezing of the object after entering. When the object is small, the baffle 408 can reduce the cold air flowing out through the through hole 5, thereby improving the quick freezing effect.

[0035] (2) When the objects are conveyed to the interior of the machine body 1 through the conveyor 3, the fan 605 draws the external air into the box body 601 through the first air inlet hole, and enters the cooler 603 through the connecting hole. The air is cooled by the cooler 603. The cooled air enters the first air duct 604 under the action of the fan 605, and enters the second air duct 606 through the first air duct 604. Part of the cold air enters the upper end tube body 608 through the second air duct 606, and part of the cold air enters the lower end tube body 608 through the third air duct 607, and is discharged through the upper and lower sets of air outlet ducts 609, so as to cool down and quickly freeze the objects on the conveyor 3.
