Description

Technical Field

[0001] The invention belongs to the technical field of canned fruit processing, and in particular relates to a canned fruit continuous sterilization device and a sterilization method. Background Art

[0002] In the current field of canned fruit processing technology, canned fruit is a kind of fresh-keeping food that uses fresh fruit as the main raw material and undergoes processing, canning, exhaust, sealing, heat sterilization, cooling and other processes to achieve commercial sterility, thereby extending the shelf life of the food. According to different processing methods, canned fruits are divided into canned fruits in syrup, canned fruits in syrup, canned fruits in jam, and canned juice. The main representative products include canned oranges in syrup, canned pineapples in syrup, canned yellow peaches, etc. Sterilization equipment is required during processing to sterilize them and extend the shelf life of canned fruits.

[0003] The utility model patent, granted with authorization publication number CN110742120A, discloses a steam sterilization device for canned fruit, comprising a sterilization chamber, a chamber door movably connected to the front side of the sterilization chamber via a hinge, a horizontal plate fixedly connected to the top of the sterilization chamber, a screw threadedly connected to the top of the inner wall of the sterilization chamber, the top of the screw extending through the top of the sterilization chamber and fixedly connected to a rotating plate. The present invention utilizes a pull ring to pull a clamping plate outward, causing the clamping plate to rotate outward around a fixed block. This movement of the clamping plate drives a connecting ring to move, which in turn deforms a clamping spring. The canned fruit is then placed inside the clamping plate, where it is clamped as the clamping spring recovers its deformation. The rotating plate is then rotated, driving the screw, which in turn pushes the movable plate downward until the bottom of the canned fruit contacts a supporting plate. This achieves the advantage of adjustable function, resolving the problem of existing steam sterilization devices for canned fruit that are not adjustable during use.

[0004] However, the above patents have the following shortcomings:

[0005] 1. In the above patent, the canned fruit is clamped by the clamping plates inside the sterilization box to facilitate sterilization. However, during the sterilization of the canned fruit, continuous feeding is not possible. At the same time, there are sterilization dead corners in the contact area between the canned fruit and the steam, resulting in incomplete sterilization and reducing the sterilization efficiency of the canned fruit.

[0006] 2. After the above patent and commonly used canned fruits are sterilized, water stains remain on their surfaces, which are easily mixed with impurities such as dust in the air and need to be cleaned manually, which is labor-intensive and inefficient. Summary of the Invention
