Description

Technical Field

[0001] This utility model belongs to the field of corn food processing, specifically, it relates to a quick-freezing device for corn cobs. Background Technology

[0002] Corn is an important food crop, rich in protein, fat, vitamins, trace elements, cellulose and polysaccharides, and has great potential for developing highly nutritious and biologically functional foods.

[0003] When transporting edible corn on the cob, it is usually necessary to steam the corn on the cob and then freeze it to lock in its freshness. Common corn cob freezing equipment usually places the corn on a conveyor belt and then freezes it through a refrigeration device. Although this method can freeze the corn on the cob, the conveyor belt cannot guarantee that each corn cob will be frozen completely and evenly. Therefore, there is an urgent need for equipment that can freeze corn on the cob evenly.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To address the technical problems existing in commonly used corn cob quick-freezing equipment, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] The quick-freezing chamber is a rectangular pipe. A drive shaft is symmetrically connected inside the chamber. A motor for driving the drive shaft is installed on the outer wall of the quick-freezing chamber. The drive shaft is cylindrical.

[0008] The spray box, which includes a fan and spraying components, is installed inside the quick-freezing chamber.

[0009] The self-rotating structure is installed inside the quick-freezing chamber to automatically rotate the corn cobs to be quick-frozen. The self-rotating structure includes a transmission belt, a turning shaft, and contact grooves. The transmission belt is symmetrically sleeved on the outer wall of the symmetrical transmission shaft. The turning shaft is rotatably connected between the symmetrical transmission belts. The contact grooves are symmetrically opened on the walls on both sides of the quick-freezing chamber. The walls of the turning shaft can hold the corn cobs.

[0010] In a preferred embodiment of this utility model, the transmission belt can drive along the symmetrical arc surface of the transmission shaft, the flipping shaft is cylindrical, and multiple flipping shafts are evenly arranged between the symmetrical transmission belts, and the two ends of the flipping shaft can roll along the symmetrical contact groove.

[0011] In a preferred embodiment of this utility model, multiple spray boxes are evenly arranged inside the quick-freezing chamber, multiple spray boxes are evenly arranged at the top of the quick-freezing chamber, and multiple identical spray boxes are also evenly arranged between symmetrical drive shafts. The air outlets of all spray boxes face upwards towards the drive belt.

[0012] In a preferred embodiment of the present invention, the self-rotating structure further includes a support plate and a top rod. The support plate is fixedly connected to the inner wall of the quick-freezing chamber, and the top rod is fixedly connected to the top of the support plate. The support plate is located on the rear wall of the front drive shaft.

[0013] In a preferred embodiment of this utility model, the support plate is a rectangular plate, and the top rod is a rod with a semi-circular cross-section. The top rods are respectively set at the top diagonal positions of the support plate, and the top arc surface of the top rod can contact the bottom wall surface of the flipping shaft above.

[0014] In a preferred embodiment of the present invention, the quick-freezing chamber is further provided with a recovery structure, which includes a condensation plate and a recovery pool. The condensation plate is fixedly connected to the inner wall of the quick-freezing chamber, and the recovery pool is fixedly connected to one side of the outer wall of the quick-freezing chamber.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a quick-freezing device for corn cobs includes: a quick-freezing chamber 20, which is in the shape of a rectangular pipe, a drive shaft 22 is symmetrically rotatably connected inside the cavity of the quick-freezing chamber 20, and a motor for driving the drive shaft 22 to rotate is installed on the outer wall of the quick-freezing chamber 20. The drive shaft 22 is cylindrical.

[0029] The spray box 21 includes a fan and a spraying assembly. The spray box 21 is installed inside the quick-freezing chamber 20. The motor and the corresponding power supply are electrically connected. The spray box 21 uses the fan and spraying assembly used in the prior art (publication number: CN220062264U). Since this is prior art, it will not be described in detail here.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a self-rotating structure is installed inside the quick-freezing chamber 20 to automatically rotate the corn cobs to be quick-frozen. The self-rotating structure includes: a transmission belt 30, a turning shaft 31, and a contact groove 32. The transmission belt 30 is symmetrically sleeved on the outer wall of the symmetrical transmission shaft 22. The turning shaft 31 is rotatably connected between the symmetrical transmission belts 30. The contact groove 32 is symmetrically opened on the walls on both sides of the quick-freezing chamber 20. The walls of the turning shaft 31 can hold corn cobs.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the transmission belt 30 can drive along the arc surface of the symmetrical transmission shaft 22. The flipping shaft 31 is cylindrical, and multiple flipping shafts 31 are evenly arranged between the symmetrical transmission belts 30. The two ends of the flipping shaft 31 can roll along the symmetrical contact groove 32. Multiple spray boxes 21 are evenly arranged in the quick-freezing chamber 20. Multiple spray boxes 21 are evenly arranged at the top of the quick-freezing chamber 20. Multiple identical spray boxes 21 are also evenly arranged between the symmetrical transmission shafts 22. All the spray boxes 21 have an outlet... All air vents face upwards from the transmission belt 30. The self-rotating structure also includes a support plate 33 and a top rod 34. The support plate 33 is fixedly connected to the inner wall of the quick-freezing chamber 20, and the top rod 34 is fixedly connected to the top of the support plate 33. The support plate 33 is located at the rear wall of the front transmission shaft 22. The support plate 33 is a rectangular plate, and the top rod 34 is a rod with a semi-circular cross section. The top rod 34 is set at the diagonal position of the top of the support plate 33, and the top arc surface of the top rod 34 can contact the bottom wall of the upper flipping shaft 31.

[0032] In practical use, the motor on the wall of the quick-freezing chamber 20 and the power supply to the spray box 21 are turned on. The symmetrical drive shaft 22 will be driven to rotate as the motor is turned on. The drive belt 30 and the turning shaft 31 can move backward as the symmetrical drive shaft 22 rotates. Then, the corn cobs to be quick-frozen are placed on the adjacent turning shaft 31 at the front opening of the quick-freezing chamber 20. When the corn cobs are placed between the adjacent turning shafts 31, they will move backward. Then, as the corn cobs pass between the upper and lower spray boxes 21, the spray boxes 21 will spray liquid nitrogen onto the corn cobs to quick-freeze them. As the corn cob moves along the flipping shaft 31, both ends of the flipping shaft 31 will automatically roll along the wall surface inside the contact groove 32. While the flipping shaft 31 is rolling, it will drive the corn cob on top of it to rotate automatically between adjacent flipping shafts 31. Then, the quick-frozen corn cob will be removed from the quick-freezing chamber 20 as the flipping shaft 31 moves backward. When the corn cob passes over the top of the top rod 34, both ends of the corn cob will gradually contact the arc surface of the top of the top rod 34. The top rod 34 can lift the corn cob, and the water remaining on the wall of the corn cob will be shaken off as the corn cob is lifted and shaken by the top rod 34.

[0033] In summary, by setting up a self-rotating structure, the corn cobs can be automatically rotated during quick-freezing in the quick-freezing chamber 20, and the top rod 34 can shake off the water remaining on the wall of the corn cobs. Therefore, this solution can ensure that each corn cob is quick-frozen evenly.

[0034] like Figure 5As shown, the quick-freezing chamber 20 is also equipped with a recovery structure, which includes a condensation plate 35 and a recovery pool 36. The condensation plate 35 is fixedly connected to the inner wall of the quick-freezing chamber 20, and the recovery pool 36 is fixedly connected to one side of the outer wall of the quick-freezing chamber 20. The condensation plate 35 is respectively set in front of each spray box 21 below. The condensation plate 35 is a rectangular plate. The top of the condensation plate 35 has a downward-facing inclined surface. The lowest point of the top inclined surface of the condensation plate 35 faces the recovery pool 36. Each condensation plate 35 is located at the air outlet at the bottom of each upper spray box 21. The side wall of the quick-freezing chamber 20 at each condensation plate 35 has a rectangular groove. The rectangular groove on the side wall of the quick-freezing chamber 20 can communicate with the recovery pool 36. The recovery pool 36 is a rectangular box with a hollow interior and an open top.

[0035] In actual use, when the upper spray box 21 sprays liquid nitrogen downwards, the excess liquid nitrogen will adhere to the top of the condensation plate 35 as it moves downwards, and then condense in the groove at the top of the condensation plate 35. The condensed liquid nitrogen will be in liquid form, and then move along the groove at the top of the condensation plate 35 toward the rectangular groove on the side wall of the quick-freezing chamber 20. After passing through the rectangular groove, it will be stored in the cavity of the recovery tank 36.

[0036] In summary, by setting up a recovery structure, excess liquid nitrogen ejected from the injection box 21 can be automatically condensed and recovered, thereby reducing the liquid nitrogen consumption of the device and effectively reducing the cost of using the device.

[0037] Working principle: When the power is turned on to the motor and spray box 21 on the wall of the quick-freezing chamber 20, the symmetrical transmission shaft 22 will be driven to rotate as the motor power is turned on. The transmission belt 30 and the flipping shaft 31 can drive backward as the symmetrical transmission shaft 22 rotates. Then, the corn cobs to be quick-frozen are placed on the adjacent flipping shaft 31 at the front opening of the quick-freezing chamber 20. When the corn cobs are placed between the adjacent flipping shafts 31, they will move backward. Then, when the corn cobs pass between the upper and lower spray boxes 21, the spray boxes 21 will spray liquid nitrogen onto the corn cobs to quick-freeze them. As the corn cobs move with the flipping shaft 31, the two ends of the flipping shaft 31 will contact the wall surface in the contact groove 32 and roll automatically. While the flipping shaft 31 is rolling, it will drive the corn cobs on top of it to rotate automatically between the adjacent flipping shafts 31. Then, the quick-frozen corn cobs will be removed from the quick-freezing chamber 20 as the flipping shaft 31 moves backward.
