Juicer and juicing method thereof

Abstract

The invention discloses a juicer comprising a main control unit, a juicing assembly and a juice receiving part. The juice receiving part is provided with a first deep ultraviolet sterilization module comprising a first deep ultraviolet light source, a first shielding cover and a first driving unit. The first driving unit drives the first shielding cover to shield or expose a light emitting side of the first deep ultraviolet light source, and good disinfection, sterilization and bacteriostasis effects are guaranteed. According to a disclosed juicing method, after juice is squeezed, the juice contained in the juice receiving part is irradiated by deep ultraviolet light and stirred. In the process that the juice is irradiated by the deep ultraviolet light, the juice is stirred, so that the juice can be uniformly irradiated by the deep ultraviolet light, and sterility is ensured. According to the disclosed juicing method, after the juice is squeezed, air in the juice receiving part is exhausted by an evacuating device, the juice is prevented from being oxidized, moreover, the juice can further be subjected to disinfection, sterilization and bacteriostasis through the deep ultraviolet light, and the juice can retain freshness for a long time.

Description

technical field [0001] The technical field of household electrical appliances of the present invention particularly relates to a juice extractor and a juice extracting method thereof. Background technique [0002] As a machine that can quickly squeeze fruits and vegetables into vegetable juice, a juicer is widely sought after by the public because of its ease of use. However, there may be food safety hazards in the juicing process, such as the use of unclean knives, cutting boards and uncleaned juicers when cutting the fruit before juicing. In the prior art, some juice extractors use an ultraviolet sterilizing device on the upper part or the side wall of the juice cup of the juice extractor, but this method will cause the pomace produced during the juicing process to stay on the ultraviolet sterilizing device Affect the efficiency of ultraviolet sterilization, coupled with the high concentration of fruit juice and poor light transmittance, resulting in low acceptance rate o...

However, there may be food safety hazards in the juicing process, such as using dirty knives, cutting boards when cutting the fruit before juicing, and using an uncleaned juicer when juicing

In the prior art, some juice extractors use an ultraviolet sterilizing device on the upper part or the side wall of the juice cup of the juice extractor, but this method will cause the pomace produced during the juicing process to stay on the ultraviolet sterilizing device Affect the efficiency of ultraviolet sterilization, coupled with the high concentration of fruit juice and poor light transmittance, resulting in low acceptance rate of deep ultraviolet light. Usually, the juice on the surface receives a certain amount of deep ultraviolet light, while the juice inside is difficult to receive deep ultraviolet light. Can not achieve effective sterilization of fruit juice

Existing fruit juices cannot be stored for a long time after they come out, and need to be drunk immediately, otherwise the juice will be stale or even deteriorated
