CN2231164Y - Arc knife for asparagus skin - Google Patents

Abstract

The utility model provides an arc-shaped knife for asparagus skins. An arc-shaped blade (1) and an arc-shaped blade (6) which are of different curvature radius are arranged on a knife body (5); the lower part of each of the blades is respectively provided with a cutting edge (4); a baffle plate (2) which has the same shape of each of the blades is fixed on the knife body (5); a knife handle (3) is fixed on the baffle plate. The utility model has the advantages of simple structure, convenient operation, high labor efficiency, low attrition rate, high yield rate and good appearance quality of cut asparaguses.

Description

Asparagus peel arc sharpener

The utility model relates to a kind of paring knife, particularly a kind of knife that is used to cut asparagus peel.

Before this, the blade that is used to cut the knife of asparagus peel all is straight.During with the paring knife of vertial knife edge, the asparagus that to have cut a diameter be 9-22mm needs 8-12 cuttves approximately.The cutter number is many more, and productivity ratio is low more, but the yield height of asparagus, the proportion of goods damageds are little.Because, when peeling with vertial knife edge, except skin, a part of asparagus meat of also pruning.Theoretically, the proportion of goods damageds are 9.97% when with 8 cuttves a cylindrical asparagus being whittled into 8 prisms, and when being whittled into 10 prisms, the proportion of goods damageds are 6.4%, and when being whittled into 12 prisms, the proportion of goods damageds are 4.46%.Be difficult to during owing to peel grasp, the proportion of goods damageds on historical facts or anecdotes border are higher than above theoretical value far away, waste very big.

The purpose of this utility model provides a kind of improved asparagus peel sharpener, and to raise labour productivity, rate reduces the wastage.

The utility model is achieved in that on this paring knife two curved blades that radius of curvature is different are arranged on the cutter hub, and the bottom of curved blade is a cutting edge, is fixed on the cutter hub with the plate washer of blade conformal, and handle of a knife is fixed on the plate washer.

Take the asparagus peel arc sharpener of said structure, easy to use, the efficiency height, the proportion of goods damageds are low, the yield height, the asparagus meat presentation quality of cutting out is good.

Below in conjunction with description of drawings structure of the present utility model.

Fig. 1 is A of the present utility model-A profile.Fig. 2 is that its B is to view.

As shown in drawings, on the asparagus peel arc sharpener of the utility model, different curved blade of radius of curvature (1) and curved blade (6) are arranged on the cutter hub (5), the bottom of curved blade is cutting edge (4), be fixed on the cutter hub (5) with the plate washer (2) of blade conformal, handle of a knife (3) is fixed on the plate washer (2).

Between plate washer and the curved blade certain clearance is arranged, the size in this gap equals the thickness of the asparagus peel that will prune.What dotted portion was represented among Fig. 1 is asparagus.Two curved blades that radius of curvature is different are for the asparagus that adapts to the diameter thickness great disparity is designed.Utilize this arc sharpener, the asparagus that to have cut a diameter be 9-25mm only needs 6-8 cuttves, and because blade is an arc, the loss of asparagus meat is few, thereby has improved efficiency greatly, has reduced the proportion of goods damageds.

Claims (1)

1. Asparagus peel arc paring knife, it is characterized in that, on described paring knife, different curved blade of radius of curvature (1) and curved blade (6) are arranged on the cutter hub (5), the bottom of curved blade is cutting edge (4), be fixed on the cutter hub (5) with the plate washer (2) of blade conformal, handle of a knife (3) is fixed on the plate washer (2).
