Embodiment 1

[0026] A food sterilization method, comprising the following steps:

[0027] S1. After washing 115g of rice with clear water, place it in water and soak for 60 minutes;

[0028] S2. Pack the soaked rice in a lunch box, and then put the lunch box into figure 1 Microwave irradiation is carried out in the food sterilization equipment shown, the microwave power is 1000W, and the microwave irradiation time is 60s.

[0029] The above-mentioned food sterilization equipment includes a furnace body 1 and a conveyor belt 3. The furnace body 1 is composed of an inner wall and end covers fixedly connected to the left and right sides of the inner wall. Eight magnetrons 2 are evenly distributed on the upper surface of the inner cavity of the inner wall. The upper surface of the cavity is provided with an air induction pipe 8 . The middle part of the end cover is provided with a through hole, which is convenient for the conveyor belt 3 to pass through.

[0030] The left and right ends of ...

Abstract

The invention belongs to the technical field of food processing, and particularly relates to a food sterilizing method. The food sterilizing method comprises the following steps of S1, washing food materials, and soaking the washed food materials; and S2, stuffing the food materials obtained in S1 in a container, and performing microwave sterilization, wherein the conditions of the microwave sterilization are that the container is kept sealed, the microwave irradiation power is 750-1200W, and the microwave irradiation time is 50-70s. Through the adoption of the food sterilizing method disclosed by the invention, the sterilizing effect can be quickly achieved under a lower temperature, especially microwave sterilization on cooked rice can be completed within only 50s, and compared with a conventional microwave sterilization technology, the food sterilizing method has the advantage that the time is saved by 30% or above; and besides, the sterilizing time is short, so that nutrients in foods can be better reserved.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a food sterilization method. Background technique [0002] Traditional food sterilization equipment is mainly sterilized by steam, that is, by heating, the water in the sterilizer compartment is boiled to generate steam. Air valve, continue heating. At this time, because the steam cannot overflow, the pressure in the sterilizer is increased, so that the boiling point is increased, and a temperature higher than 100 ° C is obtained, resulting in the coagulation and denaturation of the bacterial protein to achieve the purpose of sterilization. The traditional steam sterilization method is widely used, but there are disadvantages such as low degree of automation, high energy consumption, and large floor space in mass production. [0003] With the popularization of microwave technology, continuous food production becomes possible. For example, tunnel ovens can bak...
