Liquid spiral pipe microwave sterilization equipment and sterilization method applying equipment

Abstract

The invention discloses liquid spiral pipe microwave sterilization equipment and a sterilization method applying the equipment. The sterilization equipment comprises a material conveying unit and a microwave unit, the material conveying unit comprises a sterilization tank, a sterilization cavity is formed inside the sterilization tank, a feeding port and a discharging port are formed in one side of the sterilization cavity, a material conveying pipe is fixedly connected in the sterilization cavity, the material conveying pipe is arranged in a spiral structure in the sterilization cavity, the microwave unit comprises a first microwave unit set and a second microwave unit set, the first microwave unit set is fixedly connected to the inner side wall face of the sterilization tank, and the second microwave unit set is fixedly connected to the upper surface in the sterilization tank and located at the position of the vertical center line of a pair of spiral pipes. Compared with traditionalpasteurization, the liquid spiral pipe microwave sterilization equipment and the sterilization method applying the equipment have the advantages that the sterilization temperature rises quickly, the sterilization temperature is low, the color and taste of a finished product can be ensured, and the loss of nutritional ingredients can be reduced.

Description

technical field [0001] The invention relates to the technical field of microwave sterilization, in particular to a liquid spiral tube microwave sterilization equipment and a sterilization method using the equipment. Background technique [0002] Food is easily contaminated and deteriorated during production, storage, transportation and sales. Conventional technologies such as high temperature, drying, blanching, pasteurization, freezing, and preservatives can usually be used to achieve insecticidal and fresh-keeping of food, but this often affects the original flavor and nutritional content of food. [0003] For example, the notification number is CN109363061A in the invention patent, which discloses a pasteurization system and method, including a pasteurization machine, which includes a pasteurization machine internal heat exchanger and a cooler; the pasteurization machine internal heat exchanger will The input material to be sterilized is heated and output the sterilized ...

Problems solved by technology

Conventional technologies such as high temperature, drying, blanching, pasteurization, freezing, and preservatives can usually be used to achieve insecticide, sterilization and preservation of food, but often affect the original flavor and nutritional content of food

[0003] For example, the notification number is CN109363061A in the invention patent, which discloses a pasteurization system and method, including a pasteurization machine, which includes a pasteurization machine internal heat exchanger and a cooler; the pasteurization machine internal heat exchanger will The input material to be sterilized is heated and output the sterilized material; the cooler cools the sterilized material output by the internal heat exchanger of the pasteurization machine and then outputs it to the filling equipment. However, the pasteurization effect on liquid sterilization is general and the process is cumbersome. For example, in the invention patent with the notification number CN102150921A, an integral continuous high-temperature water bath sterilizing device is disclosed, which belongs to a sterilizing device and includes an integral box body and a circulating conveying mesh belt, and the circulating conveying mesh belt is placed inside the integral box body , and drive it to run through the power device, the interior of the integral box includes a feed section, a sterilization section and a discharge section, and each section is equipped with a straight barrel beam, and water bath sterilization is likely to cause the liquid to change color and taste And the loss of nutrients affects the overall quality of the liquid. For example, the notification number is CN107252030A in the invention patent, which discloses a microwave sterilization system, which includes a microwave sterilization device for microwave sterilization of products and a UV sterilization device for products. The ultraviolet sterilization device and the sealing device for sealing the product also include a conveyor belt for conveying the product. The conveyor belt runs through the microwave sterilization device and the sealing device. The ultraviolet sterilization device and the sealing device are all located at the For export, however, microwave sterilization is the same as the traditional sterilization method, which can only sterilize solid raw materials. When sterilizing liquid, it needs to be packaged before proceeding. The process is cumbersome, time-consuming and labor-intensive.
