A kind of automatic discharge juice extractor and deslagging juice press method thereof
Technical field
The present invention relates to food processing field, be specifically related to a kind of automatic discharge juice extractor and deslagging juice press method thereof.
Background technology
The Along with people's growth in the living standard; Various small household appliances are come into every family successively, and mixer, egg-whisk, juice extractor etc., juice extractor are a kind of small household appliances that are used for squeezing fruits and vegetables group foods such as various fruit juice, vegetables; Powerful; Can be used for making various beverage made of fruits or vegetables, satisfy the needs of consumer's health diet, easy to use.
Existing high speed juice extractor all is to adopt centrifugal force to carry out slag, juice separation; Extract fruit juice; Mainly be divided into common high speed juice extractor and get rid of two types in juice machine, but the operation principle of two kinds of juice extractors has all determined to be difficult to separately the shortcoming that overcomes, causing all has very big defective in producing and using.
As shown in Figure 1; The motor 50 of common high speed juice extractor is connected with filter screen 20; During work, fruit moves downward and gets in the charging aperture, and fruit is got rid of to filter screen 20 inwalls by centrifugal force by cutterhead 10 chopping backs; Fruit juice is filtered to collection in the Sheng juice chamber 30 through the aperture of filter screen 20, and is discharged by fruit juice outlet 60; And pomace moves upward along filter screen 20, breaks away from filter screen 20 at last and discharges through pomace outlet 40, and this type of juice extractor is called again throws slag formula juice extractor at a high speed.Filled arrows is the moving line of pomace among the figure; Hollow arrow is the moving line of fruit juice.But; The cutting speed of cutterhead 10 is very high, and the centrifugal force that produces after the chopping fruit is very big, and the speed that fruit is thrown out of is also very fast; Behind filter screen 20 walls of running into inclination in the process that throws away; Inclination filter screen 20 will produce a component that makes progress to pomace, and with the pomace filter screen 20 of dishing out rapidly, whole pomace rests on time on the filter screen 20 probably about 0.1 second.The fruit juice that the so short time causes pomace to contain can't fully be filtered by filter screen 20 and throw away, so the crushing juice rate of common high speed juice extractor is relatively low.
As shown in Figure 2, the motor 50 that gets rid of the juice machine is connected with cutterhead 10, cutterhead 10 rotation at a high speed; Filter screen 20 low speed rotation; During work, fruit moves downward the entering charging aperture, and fruit is got rid of to filter screen 20 inwalls by centrifugal force by cutterhead 10 chopping backs; Fruit juice is upwards thrown away after through the slit of filter screen 20 to containing in the juice chamber 30 and is collected, and is discharged by fruit juice outlet 40; Because filter screen 20 adopts the cylinder tubbiness, sidewall is vertical, and pomace 60 will rest on filter screen 20 inwalls always, just is removed up to shutting down.Figure hollow core arrow is the moving line of fruit juice.Because pomace 60 bears action of centrifugal force in machine in the whole process of squeezing the juice always, the fruit juice that pomace 60 contains will be thrown away fully, and time of on filter screen 20, stopping of pomace 60 is infinity in theory.Because filter screen 20 exactly likes a cage, this type of juice extractor is called cage storage slag formula juice extractor again.The low problem of common high speed juice extractor crushing juice rate, the other problems of having derived have again been solved though get rid of the juice machine.At first, because pomace 60 constantly accumulates filter screen 20 in, along with the increase of cumulative thickness, the resistance that fruit juice is thrown out of is also increasing, thus its crushing juice rate is not for we imagine so high; Secondly, because pomace 60 can't be evenly distributed on filter screen 20 inwalls in the process of squeezing the juice, thereby can produce certain out-of-balance force, the filter screen 20 that causes rotating produces vibration and noise, to the service life of machine and user's experience very big influence being arranged all.
