Continuous secondary sterilization machine

Abstract

The invention discloses a continuous secondary sterilization machine, at least comprising a conveying device and a sterilization device. The machine also comprises a water-tightseal device and an external steam circulation system, wherein the water-tightseal device is arranged at the opening of the sterilization device; the conveying device enters and exits the sterilization device through the water-tightseal device; the part of the conveying device, which is positioned inside the sterilization device and carries out continuous conveying is an internal transmission mechanism, and the part of the conveying device, which is positioned outside the sterilization device and carries out clearance halt type conveying, is an outer transmission mechanism; and the external steam circulation system provides sterilizing steam to the inside of the sterilization device. The machine of the invention ensures the secondary sterilization process to be continuous, removes mass heavy manual work, realizes full automation, and greatly improves the production efficiency.

Description

technical field [0001] The invention relates to light industrial machinery, in particular to a continuous secondary sterilization equipment used in industries such as food or pharmacy. Background technique [0002] With the rapid development of the food industry, the technical requirements for assembly line equipment in the field of food machinery are also increasing. Sterilization equipment is the key equipment in the food production process. In order to prolong the shelf life of food, it is necessary to sterilize the food after packaging, which not only kills the possible pathogenic bacteria in the food, but also keeps the important nutrients of the food and the color, aroma and color of the food from being damaged. [0003] Existing sterilization equipment is mainly divided into static type and rotary type. Static sterilization equipment has the simplest structure and is the most traditional, but has low heating efficiency and the lowest degree of automation. Rotary st...

Problems solved by technology

[0004] However, the above two types of sterilization equipment cannot be separated from the large amount of heavy work when manually loading and unloading food packaging before and after the sterilization process, which not only reduces production efficiency, but also easily causes re-contamination

[0005] Moreover, most of the traditional sterilization equipment divides the sterilization step and the cooling step into two devices, which makes it difficult to shorten the interval between the two steps, which is not conducive to maintaining the physical indicators of the object to be sterilized. The flavor, color, quality or flora activity are poor

[0006] Moreover, because the existing sterilization equipment is not completely sealed, the steam leakage is relatively serious, resulting in high energy consumption of the sterilization equipment, and it is not very environmentally friendly.
