The equipment has the effect of improving the uniformity of pinhole distribution.

Description

technical field [0001] The present application relates to the technical field of piercing equipment, in particular to a fruit piercing equipment and a piercing method. Background technique [0002] Candied fruit is a kind of product made of fruit as the main raw material, adding food additives and other auxiliary materials, and marinating with sugar or honey. Before the fruit is pickled, in order to increase the rate at which the fruit absorbs sugar, holes are usually pierced on the surface of the fruit with a piercing device. [0003] At present, the Chinese utility model patent whose notification number is CN201541679U discloses a kind of fruit and vegetable punching machine, comprising a feed hopper and a stepping conveyor belt installed on the frame. A needle guide plate is arranged above the tail end of the stepping conveyor belt, a needle assembly plate is arranged on the needle guide plate, and a plurality of needles distributed on the needle assembly board correspon...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that there are the following defects: in the process of pricking holes, the fruit is driven away from the stepping conveyor belt when the needle is pulled out and then falls. During the falling process, the range of motion is not large, and the state of the fruit is difficult to change greatly. Therefore, the positions of the pinholes are roughly the same, resulting in uneven distribution of pinholes on the surface of the fruit.
