Description

Automatic kiwi fruit juice squeezes gets device based on food processing

Technical Field

The invention relates to the technical field of food processing, in particular to an automatic kiwi fruit juice squeezing device based on food processing.

Background

Kiwifruit is native to southern china, is about the same size as a duck egg (about 6 cm high, about 4.5 to 5.5 cm circumference), and is generally oval. Dark brown and hairy epidermis is generally not edible. The kiwi fruit juice is prepared from bright green pulp and multiple rows of black seeds, is a raw material of a delicious beverage, and is collected by squeezing the kiwi fruit juice.

Through retrieval, for example, a patent with the patent number of CN107319904B discloses a kiwi fruit squeezing and juicing device, which comprises a juicing device shell, wherein a rotating seat is arranged in the middle of a supporting frame, a rotating shaft is movably connected onto the rotating seat, a juicing device head is movably connected to the top of the juicing device shell, a rotating motor is arranged in the juicing device head, and a residue discharge chamber is arranged at the lower part in the juicing device shell, the kiwi fruit squeezing and juicing device has the beneficial effects that: the kiwi fruit squeezing device is novel in structure, juice and pulp in kiwi fruit can be more thoroughly separated by squeezing juice through the cutting spiral blade and the squeezing spiral blade, in addition, the lower sides of the squeezing barrel and the spiral blade are provided with the residue discharge port and the residue discharge chamber, after the juice squeezing is finished, the juice can be discharged into the residue discharge chamber through kiwi fruit residues through the rotation of the spiral blade, the kiwi fruit residues can be conveniently cleaned, the use is more convenient, meanwhile, the squeezing device is simple and flexible in structure, and the use performance and the squeezing efficiency of the squeezing device are improved.

For another example, patent No. CN103052344B discloses a kiwi juicer with a pressed section of kiwi fruit, which requires a weak force for rotation, effectively juices pulp and juice, prevents fiber blockage, and reduces juicing residue of pulp. The protruding part (2) of kiwi fruit juicer (1) includes: a dome-shaped portion (21); and a conical shape portion (22) set in a conical shape from a base end portion (21a) thereof; a plurality of ribs (23) are provided on the outer surface of the protrusion (2). The ribs (23c, 23d) of the conical part (22) and the rib (23a) higher than the dome-shaped part (21) can effectively stir out the pulp of the kiwi fruit, shorten the cooking time and provide the fun of cooking. In addition, clogging of the rib (23) caused by the fiber of kiwi fruit can be suppressed by the lower rib (23b) at the dome-shaped portion (21).

However, because the outside of kiwi fruit has the epidermis, can cause the pollution when squeezing, general squeezing mode need cut the skin in advance, otherwise mix the kiwi fruit skin in the juice easily, seriously influence the quality of kiwi fruit juice, debris fall inconvenient the discharge in the kiwi fruit juice, consequently, unsatisfied current demand, to this we propose an automatic kiwi fruit juice squeezing device based on food processing.
