Description

Technical Field

[0001] The utility model belongs to the field of frozen food production, and in particular relates to a cooling device for pill-shaped and slippery products. Background Art

[0002] In the production process of fish balls, after being formed and pre-cooked, the fish balls are first cooled, and then quickly frozen and packaged. The method of first water cooling and then air cooling can make the fish balls cool down quickly, and at the same time achieve the effect of air drying, and prevent the residual moisture on the surface of the product from affecting the subsequent freezing. Fish balls are mostly spherical, with low density and light weight. If a cold water bath is used, the product will float on the water surface and cannot be effectively cooled. Utility model patent CN208205742U discloses a fish ball air-drying and freezing device, in which the fish ball air-drying and cooling mechanism includes a multi-layer conveyor belt, and the multi-layer conveyor belt is arranged from top to bottom at a certain interval using multiple conveyor belts, and the conveying directions of the upper and lower adjacent conveyor belts are opposite. Cooling water nozzles are installed above the two ends of each layer of the conveyor belt, and a row of cooling fans blowing forward are installed behind each layer of the conveyor belt to air-dry and cool the fish balls cooked at high temperature. This patent can achieve cooling of the meatballs, but the water spray outlets at both ends of the conveyor belt will cause the following problems: 1. The cooling water sprayed from the water spray outlets is affected by the fan, and some cooling water will be blown away, resulting in poor spraying effect and waste of water resources; 2. Water spray outlets are set on each layer, and the moisture on the surface of the meatballs may not be blown dry after cooling, affecting subsequent freezing; and the conveyor belt in this patent uses steel plates, which have poor air permeability and are not conducive to air drying of moisture.

[0003] In order to solve the above problems, the utility model provides a cooling device for pill-like products.

[0004] The purpose of the utility model is achieved in the following ways:

[0005] A cooling device for pill-like products includes an air-drying cooling device 1, wherein the air-drying cooling device 1 includes a multi-layer chain conveying mechanism 11, wherein the conveying directions of two adjacent layers of the chain conveying mechanism 11 are opposite, and the starting end of the lower layer of the two adjacent layers of the chain conveying mechanism 11 extends out of the end of the upper layer; a cooling fan 14 is arranged on one side of the chain conveying mechanism 11, and a cooling water spraying device 2 is arranged upstream of the air-drying cooling device 1.

[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] A cooling device for ball-like products comprises an air-drying cooling device 1, wherein a cooling water spraying device 2 is arranged upstream of the air-drying cooling device 1, and the cooling water spraying device sprays cooling water to cool the balls for the first time, and then the balls enter the air-drying cooling device for air-cooling and drying the moisture on the surface of the balls. The cooling water spraying device 2 is arranged before the air-drying cooling device 1, so as to avoid the spraying water from being affected by the cooling wind and flying around, thereby saving water resources. At the same time, it is ensured that the moisture on the surface of the balls is fully dried by air, so as to facilitate subsequent freezing.

[0015] The cooling device for ball-like products, the air-drying cooling device 1 comprises a multi-layer chain conveying mechanism 11, the conveying directions of the two adjacent layers of chain conveying mechanisms 11 are opposite, and the starting end of the lower layer in the two adjacent layers of chain conveying mechanisms 11 extends out of the end of the upper layer; a cooling fan 14 is arranged on one side of the chain conveying mechanism 11. In the air-drying cooling device 1, the balls fall from the end of the upper chain conveying mechanism 11 to the starting end of the lower chain conveying mechanism 11, and are transported in an S shape from top to bottom, while the cooling fan 14 blows out cooling air to cool down and dry the moisture on the surface of the balls. The S-shaped path ensures that the balls have a sufficiently long transportation path in the air-drying cooling device 1, ensures that the balls are reduced to the required temperature, and dry the surface moisture.

[0016] In the cooling device for ball-like products, the starting end of the uppermost chain conveying mechanism 11 is located below the discharging end of the ascending mechanism 3, and the ascending mechanism 3 is a chain conveying mechanism 11 with an obliquely upward transmission direction; a baffle 31 is provided on the ascending mechanism 3 to prevent the balls from sliding obliquely downward. The ascending mechanism 3 is used to transport the balls to the uppermost chain conveying mechanism 11. Since the ascending mechanism 3 is transported obliquely upward, the balls are spherical and easily roll, and the baffle 31 is used to block the rolling balls.

[0017] In the cooling device for pill-shaped products, the cooling water spray device 2 is arranged above the rising mechanism 3, and the cooling water spray device 2 includes a cooling water pipe 21 for conveying cooling water, and a nozzle 22 for spraying cooling water is arranged on the cooling water pipe. In order to achieve a better cooling effect, a plurality of cooling water pipes 21 are arranged above the rising mechanism 3, and a plurality of nozzles 22 are arranged on each cooling water pipe.

[0018] In the cooling device for ball-like products, the conveying carrier of the chain conveying mechanism 11 is a metal rod 13 with gaps and fixed at both ends on the chain 12, and the gap between adjacent metal rods 13 is smaller than the diameter of the ball. The diameter of the ball is larger than the spacing between the metal rods 13, and the ball is located in the gap between the two metal rods 13 during transportation, which can prevent the ball from rolling. The chain conveying mechanism replaces the existing plate chain conveyor metal plate with a metal rod. Compared with a conveyor belt or a metal plate, the metal rod has a larger gap and a good ventilation effect, which is convenient for cooling the ball and air drying the surface moisture.

[0019] The working process of the utility model is as follows:

[0020] After being cooked in the water bath heating link upstream, the balls enter the ascending mechanism 3 and fall into the gap between the metal rods 13 of the chain conveying mechanism 11. The balls rolling down are caught by the baffle 31 and transported upward together with the chain conveying mechanism 11. During the transportation, the nozzle 22 sprays cooling water to cool the balls. The end of the ascending mechanism 3 is located above the starting end of the chain conveying mechanism 11 on the uppermost layer of the air-drying cooling device 1. The balls fall from the end of the ascending mechanism 3 to the starting end of the chain conveying mechanism 11 on the uppermost layer, and then fall from the end of the upper chain conveying mechanism 11 to the starting end of the lower chain conveying mechanism 11, and are transported from top to bottom in an S shape. At the same time, the cooling fan 14 blows out cooling air to cool down and dry the moisture on the surface of the balls.

[0021] The above is only a preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
