Embodiment 1

[0020] Example 1: Orange juice is sterilized by UHT at 135°C, kept warm for 4-15 seconds, and finally cooled to 30-35°C for filling. After microwave sterilization for 3-5 minutes, it can be stored at room temperature, and the shelf life can reach more than 6 months.

Embodiment 2

[0022] The processing method of green tea: the temperature is 130-135 ℃ by ultra-high temperature instantaneous sterilization, heat preservation for more than 4 seconds, and finally cooled to 55-60 ℃ for filling; sterilized by microwave for 2-3 minutes, can be stored at room temperature, The shelf life can reach more than 6 months.

[0023] Special sterilization equipment for liquid food, including UHT or high temperature sterilization equipment, filling equipment and special tunnel microwave sterilization equipment. The microwave treatment box of the tunnel microwave sterilization equipment is equipped with a conveyor chain speed control device. The microwave generation power of the magnetron in the microwave processing box is controlled by the temperature control system; the microwave processing box is equipped with a magnetron power control switch, an observation window, a magnetron and a feed port. The microwave processing box is equipped with an observation window and the...

Abstract

The invention relates to a sterilizing method for liquid food. Carrying out UHT (ultrahigh temperature) or high-temperature sterilization and reduced temperature filling to the liquid food, then carrying out sterilization through a special microwave sterilization device, and then cooling the sterilized liquid food to room temperature to obtain the finished product; when the filling temperature decreases to 25-65 DEG C, carrying out microwave sterilization immediately; and particularly when the filling temperature decreases to 40 DEG C plus or minus 5 DEG C, carrying out microwave sterilization immediately. The UHT or high-temperature sterilization is carried out at a temperature of 121 DEG C above, the microwave sterilization temperature can be lower, according to the method and the device, the microwave sterilization after filling can be carried out to the non-high-temperature soft bags, plastic bottles, glass bottles and other nonmetal bottles at a higher temperature, the general disinfection is required to be carried out to the pipes, bottles, bottle caps, air and the like, the cost is low, the management difficulty is low, and the secondary bacterial pollution is avoided due to the sterilization after filling.

Description

technical field [0001] The invention relates to a novel sterilization method and special microwave sterilization equipment for liquid food and other liquid articles. Especially the method and equipment of microwave sterilization after UHT+filling. Background technique [0002] The sterilization method of liquid food and other liquid articles is an important technical means for food sterilization and preservation. Liquid food in the present invention refers to various liquid beverages, alcoholic liquid food and other liquid foods. The special microwave sterilization equipment here refers to the microwave sterilization equipment specially used for sterilization of liquid food after filling. [0003] In the prior art, liquid food and other liquid items generally use UHT, Ultra High Temperature treated ultra-high temperature instantaneous treatment method, ultra-high temperature instantaneous sterilization, 130-140 ° C, 1.5-15 seconds, is a kind of sterilization for this type o...
