Description

Technical Field

[0001] The utility model relates to a water bath type sterilizing kettle, belonging to the technical field of sterilizing kettles. Background Art

[0002] When the sterilizer is sterilizing the product, the product is placed in the sterilizer, and then circulating hot water is passed into the sterilizer to sterilize the product in the sterilizer.

[0003] In the prior art, the water circulation mode in the sterilizing kettle is from top to bottom. During the entire sterilization process, since the intermediate products have a relatively large resistance to water, most of the water will not flow through the gaps between the products, resulting in a poor sterilization effect in the middle of the products. In addition, the heat of the hot water will decrease as it flows downward, which will cause the products in the middle and at the bottom to receive less heat, resulting in poor heat distribution. Furthermore, during the continuous circulation of water, some bagged products will stick to the wall of the pot, resulting in a situation where not all the materials can be discharged.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] The utility model aims at the deficiencies in the background technology and provides a water bath sterilizer, which can achieve good heat distribution effect in the sterilizer, evenly heat the products and achieve good sterilization effect; in addition, it can also solve the problem of incomplete feeding of bagged products.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A water bath sterilizing kettle comprises a circular inner cylinder, the upper end of which is open, a top spray pipe is arranged at the upper opening of the inner cylinder, a plurality of water outlet holes are arranged at the lower end of the top spray pipe, the lower end of the inner cylinder is in a tapered funnel shape, and a discharge port is arranged at the bottom of the inner cylinder.

[0008] An outer cylinder is sleeved on the outer side of the inner cylinder, an annular cavity is formed between the inner cylinder and the outer cylinder, a plurality of side spray pipes are vertically arranged in the annular cavity, and a plurality of water outlet holes are arranged on the side of the side spray pipe facing the inner cylinder.

[0009] Furthermore, the top spray pipe includes a top first spray pipe and a top second spray pipe, and the top first spray pipe and the top second spray pipe are annular pipes with different diameters.

[0010] Furthermore, the first spray pipe and the second spray pipe on the top are connected through a connecting joint, and a first water inlet pipe is provided on the connecting joint.

[0011] Furthermore, a plurality of water inlet holes are arranged on the wall of the inner cylinder.

[0012] Furthermore, a water distributor is provided on the top of the annular cavity, and the water distributor is an annular water storage device. A second water inlet pipe is provided on the water distributor, and the top of the side spray pipe is connected to the annular water storage device.

[0013] Furthermore, the water distributor includes a first water distributor and a second water distributor, both of which are semicircular and symmetrically arranged on both sides of the top of the annular cavity. The upper ends of the first water distributor and the second water distributor are both provided with a second water inlet pipe, and the lower ends are both vertically installed with multiple side spray pipes.

[0014] Furthermore, a plurality of water flow blocking rings are arranged in an upper and lower interval pattern in the annular cavity.

[0015] Furthermore, a plurality of drain holes are arranged on the water flow blocking ring.

[0016] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:

[0017] 1. Supply water alternately to the first water distributor and the second water distributor, so that the side spray pipes on both sides of the annular cavity spray water alternately, so that the hot water flowing into the inner cylinder from the annular cavity flows horizontally from one side to the other side (if both sides spray water to the middle, the hot water flows slowly in the middle of the inner cylinder, which is not convenient for sufficient heat exchange), so that the product in the middle is fully in contact with the hot water, thereby enhancing the heat exchange effect.

[0018] 2. As there is a water inlet hole on the wall of the inner cylinder, water flows in from the inner cylinder, so that small and thin bagged products will not be adsorbed on the inner wall, making material discharge smoother.
