Description

Potato peeling machine

Technical Field

The invention relates to food machinery, in particular to a special processing machine for removing potato skins, and particularly relates to a potato peeler which only removes outer thin film skins of potatoes without damaging subcutaneous flesh and flesh.

Background

The potato is widely accepted as an agricultural product with wide adaptability and huge yield because of rich nutrition and various making patterns, but the potato needs to be peeled off in the process of processing raw materials into food, the problem of difficult operation of the peeling procedure is not solved well in a long period, mainly because the appearance of the potatoes is not regular, or the potatoes are round, long round or sectional and have various shapes, and the surfaces of the potatoes are also provided with a plurality of pits and uneven, in recent years, a drum type electric potato peeling machine is provided, which utilizes high-speed rotation of a rotating wheel arranged at the bottom of a drum to drive potatoes to rub on the inner wall of the drum for peeling, coats a layer of carborundum coating on the inner wall of the drum, and utilizes collision friction for peeling; the other type is a shaft roller type, peeling is carried out by utilizing a plurality of groups of rotating rollers with hard brushes to rotate and polish in turns at high speed in an echelon manner, the structure is more complicated, but the work efficiency is higher. The two types are the most common potato peeling machines, but they have a cosmetic disadvantage: also press from both sides when getting rid of potato peel and taken away more subcutaneous flesh, the inspection of actually weighing can discover: the weight of the potatoes before and after peeling is reduced by 10-15/100, namely, about 1/7 of potatoes are wasted due to peeling, actually, according to different potato varieties, under the relatively humid condition, the thickness of the pure skin of the potatoes is 0.12-0.15mm, the weight of the pure skin of the potatoes is only about 2-3/100 of the gross weight of the potatoes, about 10/100 of fleshy flesh of the potatoes has to be wasted for removing the inedible skin, the smooth peeled potatoes processed are roughly looked straight and fine, the subcutaneous fleshy flesh is found to leave channel groove wounds along with the skin, and the total thickness of the peeled potato skin and the fleshy flesh is not less than 2-2.5mm, so that the potato is practically wasted and cannot be seen.

a plurality of tension springs 4 which are elastically supported are connected in parallel in the vertical direction between the upper frame ring 2 and the lower frame ring 5 through a hook, all adjacent tension springs are mutually close to each other and are closed together to form a cylinder, the steel wire layer 14 is uniformly covered and wound on the inner side wall surface of the tension spring which is closed into a cylindrical shape, as shown in the partial enlarged view on the left side in figure 1, the wire layer 14 is formed by winding high carbon flat wires of 0.15 x 0.5mm (thickness x width) into a thick felt shape in a cluster manner, in order to be durable, the tension springs and the steel wire layer are preferably made of stainless steel, the tension springs with good elasticity and the thick steel wire layer consisting of flat steel wires can be well matched with each other to generate the effects of tightly wrapping potatoes with different shapes and sizes and arc-shaped friction, the effect is very important for realizing the design goal that only the thin potato peel is removed without damaging the flesh and the flesh of the potato; a motor shaft 10 of the programmable motor 8 extends upwards for a section and is radially connected with a plurality of frame rods 11 on the extension section in a surrounding manner, the outer end of each frame rod 11 is jointly and fixedly connected to the inner wall of a drum 12 in an inverted U-shaped shape, the drum in the inverted U-shaped shape specifically means that the outer side wall surface of the lower half of the drum is vertical up and down, the outer side wall surface of the upper half of the drum is gradually contracted inwards, the downward opening end of the drum 12 reaches the lower end of the tension spring 4 and is close to a steel wire layer 14 at the lower end, the upward top end of the drum reaches the upper part of the upper frame ring 2, namely the lower half of the drum is parallel to and close to the upper part and the lower part of the tension spring and the steel wire layer at the outer side, and the upper half of the drum forms a wedge shape with the tension spring and the steel wire; a soft coating layer 13 is also integrally covered on the outer wall surface of the rotary drum 12, and in order to increase the friction effect, the surface of the coating layer is preferably provided with fold grooves; a hopper-shaped hopper 1 and a water spray pipe 15 are arranged above the upper frame ring 2, a material receiving dustpan 6 which extends downwards and outwards is arranged on the inner side of the lower frame ring 5 and below the lower edge of the rotary drum 12, and when the machine starts to work, the water spray pipe 15 can spray water flow downwards to wet a working surface and lower punching leather scraps, so that the working efficiency is improved; the programmable motor 8 is set to be in a reciprocating circulation working mode of rotating a plurality of circles in a forward direction and then rotating a plurality of circles in a reverse direction, when potatoes fall into a wedge-shaped cavity between the outer wall surface of the rotary drum 12 and the tension spring from the hopper 1, the rotary drum drives the potatoes to start to rub, roll and rotate in a reciprocating manner on the steel wire layer on the tension spring to polish the skins of the potatoes, the friction force between the potatoes with the skins and the contact surfaces of the potatoes with the skins is large, the falling speed is naturally slow, the tension spring with good elasticity and the thick steel wire layer consisting of flat steel wires can be well matched to generate the effect of tightly bundling and arc-shaped friction on the potatoes with different shapes and sizes, most of the potatoes are clamped in the increasingly narrow gap between the rotary drum and the steel wire layer on the outer side and repeatedly rub in a reciprocating manner for a plurality of times until the skins are efficiently cleaned, and the friction force of the smooth potatoes without the skins is greatly reduced and becomes abnormally slippery under the lubricating impact action of starch and water flow separated from the The steel wire layer can not completely penetrate the fleshy pulp of the potatoes with the skin completely removed by the wounds due to the change of the surface of the potatoes, and the potatoes can rapidly slide downwards to fall onto the material receiving dustpan through the gap between the rotary drum and the tension spring and then roll outwards to complete one-time peeling work; the potatoes with small parts of unpeeled skins have friction force slightly higher to slow down the sliding speed due to the existence of the skins, and are continuously polished in narrow gaps at the lower half section of the rotary drum until the potatoes are completely cleaned and then fall onto the material receiving dustpan, namely, the shape of the rotary drum, the matching of the tension spring and the steel wire layer and the setting of the working mode of the programmable motor can ensure that the potatoes with the skins which are firstly unpeeled fall off firstly, and the potatoes with the skins which are not completely removed can not fall off but can be continuously polished, meanwhile, the subcutaneous meat pulp is also protected, and the loss of food materials is greatly reduced. Of course, the potatoes described above should be thoroughly soaked in warm water prior to processing to substantially restore the optimum dehulling effect to a moisture content of up to about 75-78/100 after delivery.
