Description

Food processor

Technical Field

The invention relates to the technical field of food processing, in particular to a food processor.

Background

Freshly squeezed juice can be divided into two main categories: pure fruit juice and whole fruit juice. Wherein the pure fruit juice is fruit juice separated from fruit residue and fruit juice (i.e. fruit juice without fruit residue); whole fruit juice is juice (i.e., juice containing pomace) that is comminuted with the peel and pulp along with the kernel. These two juices have their own advantages and disadvantages: the pure fruit juice has good taste but lacks dietary fiber, so that the nutrition is not comprehensive; the total dietary fiber retained in the whole juice also resulted in a relatively poor mouthfeel.

The prior art is that the machine for making pure fruit juice mainly comprises a spiral type juice extractor (a separate type and a horizontal type), a centrifugal juice extractor and a piston squeezing type juice extractor, the juice extractor can both make juice with separated residue and juice, the raw materials of the machines are similar, and the specific technical structures are different.

The machine for making the whole fruit juice in the prior art mainly comprises a stirrer and a soybean milk machine, and the specific structure of the machine generally comprises a grinding motor overhead type machine, a grinding motor underneath type machine and a grinding motor side type machine. Both the blender and the soymilk machine crush fruits (foodstuff) and water into fruit juice together through the rotation of the crushing cutter device in the barrel body. Conventionally, a small-power stirrer of about 100-200 watts is called a food processor; a high-power stirrer with the power of about 1000 watts is called a wall breaking machine (the high-power crushing is more fine). The soymilk machine is also a stirrer in nature, so the soymilk machine can also be regarded as a habitual name for a certain stirrer with a heating device, and belongs to the stirrer in technical classification.

Machines for producing both pure and whole juices include vacuum and non-vacuum types, which have the advantage of avoiding oxidation of the juice.

In the prior art, machines for making pure fruit juice, such as CN201710065637.2 "electrically driven vacuum squeezer", CN201610498366.5 "electrically driven closed vacuum squeezer", etc., are all vacuum piston press type juicers, which can not only avoid the oxidation of fruit juice during the use, but also have fewer parts to be cleaned after squeezing the fruit juice, and only need to clean the squeezing cylinder, the piston and the juice receiving part, and other parts of the machine body do not need to be cleaned.

However, the existing machine can only produce 'pure fruit juice with separated dregs and juice', and cannot produce 'full fruit juice containing dregs'.

In the prior art, machines for making whole fruit juice, such as the food processor disclosed in CN201210139784.7 "food processor with electric air pump and method for making food liquid by vacuumizing", can only make whole fruit juice containing fruit residues, but cannot make pure fruit juice separated from residue and juice.

As described above, in the prior art, both of the two types of food processors represented by the squeezer and the blender can only process one kind of fruit juice, either full fruit juice or pure fruit juice, and none of the food processors can simultaneously produce full fruit juice and pure fruit juice, and only two food processors can be used to output different fruit juices.

On the other hand, the current mainstream residential building area of Chinese residents is only about 100 square meters, wherein the kitchen use area is generally only about 4 square meters. The total length of the floor panel in the kitchen is generally only 3-4 linear meters. After the area of the table top plate which is occupied by the 'first-level just needed products' of a kitchen range, a water tank, a chopping board, a dish, an electric cooker and the like is deducted, the area of the remaining table top plate is very small. Therefore, in the kitchen of the Chinese resident family, the place for placing the blender is often arranged, the place for placing the juicer is not arranged, and vice versa.
