Background

Papaya (Chaenomeles sinensis) is a plant of the genus Chaenomeles of the family Rosaceae (Rosaceae), and is distinguished from the tropical fruit papaya (Carica papaya L.) in that its dried fruit remains smooth and non-shrunken in peel. The chaenomeles speciosa is mainly produced in Henan, Shandong, Shaanxi, Hubei and other places and is a woody plant, while the papaya is originally produced in Central America and is widely cultivated in tropical regions and is a herbaceous plant. At present, papaya is sold or simply processed and eaten as fruit in the market. In recent years, the tropical fruit papaya has high edible value, is widely introduced into thousands of households, and is gradually abbreviated as papaya by people and food processing industry, so that the market and patent literature are confused about names.

The pawpaw is an important medicinal and edible tree species, the fruit of the pawpaw is rich in nutrition, contains rich compounds such as organic acid, amino acid, polysaccharide, flavone, triterpene and glycoside of the triterpene, has the effects of resisting bacteria, diminishing inflammation, resisting tumors and the like, is an important medicinal and edible tree species, integrates edible, medicinal and ornamental functions, has high development value and wide market prospect. At present, pawpaw is a characteristic medicinal material and a characteristic economic tree species of food processing raw materials (wine, vinegar and the like) in many places such as Shandong Neze, Hubei Yun county, Shaanxi Baihe, Henan Paiai and the like.

In addition, the utilization of the glabrous papaya is mainly based on ornamental value due to low benefit caused by low influence of domestic traditional Chinese medicine market. However, the glabrous papaya contains vitamin C, wherein the highest content of the vitamin C in the glabrous papaya in the sand growing region can reach 191mg/100g, the papaya fruit yield is very high and can reach 1500-.

For a long time, the smooth-skinned pawpaw has sour and astringent taste of the fruit, and simultaneously, the hardness of the fruit is very high due to more crude fibers in the fruit, so that a common pawpaw product is difficult to directly process and eat, and the common pawpaw product is only used as wine vinegar and an additive raw material in a beverage, so that the food processing and utilization basis is very weak. At present, common and directly edible papayas are available in the market, and the papayas can be directly edible, so the deep processing technology is simpler, the preserved papayas appearing in the market are preserved papayas, and no product for processing the preserved papayas by using the smooth-skinned papayas appears.

Fresh papaya with skin and smooth skin is cut into strips, seeds are removed, the fresh papaya with skin and smooth skin becomes papaya with skin and smooth skin melon strips with certain toughness after being aired for 2-4 days, and the condition that the papaya strips are broken cannot occur in the flattening and peeling process of the papaya with skin and smooth skin melon strips.

The papaya with the skin and the smooth peel is placed at the feeding end of the flattening mechanism, the flattening roller wheel 2 drives the feeding belt 10 to move when rotating, the papaya with the skin and the smooth peel placed on the conveying belt 7 can be conveyed to the flattening roller wheel 2 and between the flattening conveying roller wheel 4, the papaya with the skin and the smooth peel becomes the flat papaya with the smooth peel under the extrusion action of the flattening roller wheel 2 and the flattening conveying roller wheel 4, the peel of the flat papaya with the smooth peel is positioned on a flat plate with a thickness smaller than that of the original state, and the pulp is positioned on a flat plate with a thickness larger than that of the original state. Then the flat-plate-shaped smooth-skinned papaya peel strips are conveyed to a position between the skinning roller 3 and the skinning conveying roller 5 by the conveying belt 7 to be skinned. Wherein, it is compacter to make the pulp melon skin pressure with shelling running roller 3 and shelling conveying running roller 5, is favorable to shelling blade 6 to cut apart the connection between melon skin and the pulp, and the height that the blade part of shelling blade 6 apart from conveyer belt 7 can be adjusted according to actual conditions to it is too thick or too thin to remove the skin thickness from.

Compared with the existing peeling machine, the peeling section of the bare papaya melon strip peeled by the peeling machine is regular, and the papaya melon peel residue is very little.

As shown in fig. 5 and 6, the papaya slicer includes a slicing mechanism, a feeding mechanism, a driving mechanism, and a frame 1. The slicing mechanism is used for slicing the peeled and bare papaya melon strips; the feeding mechanism is used for conveying the peeled and polished papaya slices into the slicing mechanism for slicing; the feeding mechanism comprises an upper feeding roller group 5, an upper feeding belt 4, a lower feeding belt 6 and a lower feeding roller group 7, wherein circular bulges 9 are arranged on the outer belt surface of the upper feeding belt 4 along the length direction of the upper feeding belt 4, and two adjacent rows of circle center bulges 9 and the upper feeding belt 4 enclose a melon strip limiting groove 10; the driving mechanism is a variable frequency motor for driving the slicing mechanism and the feeding mechanism to work; the frame 1 is used for installing a slicing mechanism and a feeding mechanism. The slicing mechanism and the feeding mechanism are respectively arranged on the frame 1, the upper feeding roller set 5 is arranged right above the lower feeding roller set 7, and the slicing mechanism and the feeding mechanism are respectively in transmission connection with the driving mechanism; the feeding rollers in the upper feeding roller group 5 are in transmission connection through an upper feeding belt 4; the feeding rollers in the lower feeding roller group 7 are in transmission connection through a lower feeding belt 6.

The number of the feeding rollers in the upper feeding roller group 5 is one less than that of the feeding rollers in the lower feeding roller group 7, and one more feeding roller in the lower feeding roller group 7 than that in the upper feeding roller group 5 is arranged below the slicing mechanism; a feeding roller in a lower feeding roller group 7 is arranged right below the feeding roller in the upper feeding roller group 5. A chopping board 8 is arranged under the slicing mechanism, and the chopping board 8 is arranged at the inner side of the lower feeding belt 6 and is in close contact with the inner belt surface of the lower feeding belt 6 above the lower feeding roller group 7. The slicing mechanism comprises a slicing cutter 2 and a cutter vertical reciprocating component 3, the slicing cutter 2 is mounted on the cutter vertical reciprocating component 3, and the cutter vertical reciprocating component 3 is in transmission connection with the driving mechanism; the cutting edge of the slicing knife 2 is vertical to the upper plate surface of the chopping block 8 and is positioned right above the chopping block 8.

When the peeled smooth-skinned papaya melon strips are placed between the upper feeding belt 4 and the lower feeding belt 6, the melon strip limiting grooves 10 enable the posture of the peeled smooth-skinned papaya melon strips moving in the feeding mechanism to be consistent with the linear motion direction of the upper feeding belt 4. When the peeled smooth-skinned papaya melon strips are conveyed to the position right below the slicing cutter 2, the slicing cutter 2 slices the peeled smooth-skinned papaya melon strips, and the slicing thickness is related to the up-and-down reciprocating time of the slicing cutter 2 and the feeding speed of the feeding mechanism.

When the reciprocating time of the slicing cutter 2 and the feeding speed of the feeding mechanism are unchanged, the thickness of the papaya slices cut by the cutting device is also kept unchanged or changed little, so that the papaya slices can be classified according to the length and the width, the production added value of papaya products can be improved, the refined production of the papaya products can be facilitated, for example, slices with similar sizes can be placed in a package to be made into fine products or high-grade products, and slices with larger size difference and irregular shapes can support common products or low-grade products.
