Description

Technical Field

[0001] The invention belongs to the technical field of deep processing of potatoes. Specifically, it relates to a high-efficiency extraction system and a green and environment-friendly extraction method for dietary fiber from potato residues. Background Art

[0002] Potatoes are widely planted as cash crops, and there are also various foods and feeds made from potatoes. At present, most of the products on the market are made from potatoes in two major categories. The first category is the products obtained without separating potatoes, such as mashed potatoes, products mixed with mashed potatoes, French fries, potato chips, etc.; the second category is the extraction and separation products of potatoes, such as starch, products mixed with starch. In these two major categories of potato products, there is no product produced by solely using potato dietary fiber. Mostly, during the processing of potatoes, after the starch in the potatoes is extracted completely, the remaining residues (potato residues) are used as feed or directly discarded. However, the potato residues are rich in a large amount of dietary fiber. If only used as feed, its utilization effect is greatly reduced. Moreover, for breeding, dietary fiber is only used as a substrate. If animals take a large amount of it, it will have the opposite effect on animal fattening. Except for being used as a feed substrate, the remaining treatment method is to directly discard it. Thus, it can be seen that potato dietary fiber cannot be applied to a suitable field. If not recycled, it will cause waste of resources. Summary of the Invention

Detailed implementation mode

[0018] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present invention, and are not used to limit the present invention.

[0019] The present invention discloses a high - efficiency extraction system for dietary fiber from potato residues, as Figure 1-23As shown in the figure, it includes a skin impurity removal device 100, a vibrating slicing device 200, a press 300, a soaking tank 400, a filter cylinder 500, a continuous heat steaming device 600, and a drum dryer 700, which are arranged in sequence along the processing order of potatoes. The skin impurity removal device 100 of the present invention includes a passive feeding mechanism, a skin treatment mechanism, and a passive discharging mechanism, and the passive feeding mechanism, the skin treatment mechanism, and the passive discharging mechanism are arranged in sequence along the conveying direction of the potatoes. The vibrating slicing device 200 of the present invention includes a plurality of feeding mechanisms arranged side by side. The outlet ends of these feeding mechanisms are equipped with slicing mechanisms, and the inlet ends of these feeding mechanisms are communicated with the outlet end of the accommodating box 217. The working principle and advantages of the present invention are as follows: The present invention uses the skin impurity removal device 100 to remove impurities such as silt on the potato skin. After that, the potato skin is removed, so that the potato skin, the stubborn substances on the skin, and the mildewed parts on the skin are removed, ensuring that the potatoes remain clean during subsequent processing. Then, the potatoes are sliced so that when dehydrated by pressing in the subsequent process, the water in the potatoes can be quickly and fully removed. Then, the obtained potato residue is soaked. During the soaking process, in order to fully remove the non-dietary fiber in the potato residue, the soaking water in the soaking tank 400 can be disturbed, thereby improving the separation efficiency. Then, the potato residue is filtered out through the filter cylinder 500, and then the filtered potato residue is roll-pressed by a rolling roller to squeeze out the water in it, and the potato residue with a small volume is formed into a sheet structure. The sheet-structured potato residue is divided into small pieces and then supplied to the continuous heat steaming device 600. The continuous heat steaming device 600 performs heat steaming on the potato residue to obtain cooked potato residue. The cooked potato residue is dried, cooled, and crushed to finally obtain dietary fiber powder for use as supplementary food. In summary, the present invention can efficiently remove the impurities on the potatoes and effectively separate the dietary fiber in the potatoes by pure physical means, avoiding pollution of the dietary fiber during the extraction process, making the obtained dietary fiber safe, and can be used as supplementary food to improve the gastrointestinal environment.

[0020] As a preferred embodiment of the present invention, as Figure 2-14As shown, the epidermis processing mechanism includes a horizontal installation cylinder 101, a rotary processing assembly and a driving assembly. The rotary processing assembly is rotatably installed in the processing chamber 102 of the horizontal installation cylinder 101, the axis of the rotary processing assembly coincides with the axis of the rotary processing assembly, the driving assembly is arranged outside the horizontal installation cylinder 101, one end of the rotary processing assembly is transmission-connected with the driving assembly, and a sewage connection 103 is constructed at one end of the lower part of the outer peripheral wall of the horizontal installation cylinder 101. In this embodiment, an epidermis cleaning area 112, an epidermis hot steaming area 113 and an epidermis removal area 114 are formed in the rotary processing assembly, and the epidermis cleaning area 112, the epidermis hot steaming area 113 and the epidermis removal area 114 are arranged in sequence along the conveying direction of potatoes.

The working principle and advantages of this embodiment are as follows: this embodiment controls the action of the driving component to drive the rotary processing component to rotate in the horizontal installation cylinder 101, and the passive feeding mechanism and the passive discharging mechanism are operated accordingly, so that the potatoes entering the passive feeding mechanism are gradually conveyed to the rotary processing component, and the sludge on the surface of the potatoes is removed during the process of passing through the skin cleaning area 112; then, the potatoes pass through the skin hot steaming area 113, and their skin is hot steamed when passing through this area, so that the skin softens and is separated from the connection with the potato flesh, and then the potatoes enter the skin removal area 114, and the skin and damaged parts of the potatoes are removed, and the cleaned potatoes enter the passive discharging mechanism, and finally discharged from the skin removal and cleaning device 100. This embodiment achieves the purpose of removing impurities from potatoes by a step-by-step treatment method, improves the adequacy of impurity removal, and makes the cleanliness of the obtained potatoes reach or exceed expectations. In this embodiment, if the sludge and other impurities on the potato skin are not removed, during the subsequent hot steaming in the skin hot steaming zone 113, the potato skin is heated unevenly due to the interference of the sludge and other impurities, resulting in a situation where a local area of ​​the skin cannot be smoothly detached.

The transportation of the potatoes is mainly achieved by the spiral guide blades 111, that is, the spiral guide blades 111 are transported while the potatoes are rotating with the rotary processing component.

A fixing nut 209 is threadedly connected to the connecting column 207, and the fixing nut 209 is tightened on the adapter seat 208, thereby achieving the fixing of the transmission rod 205 and the adapter seat 208. In this embodiment, a longitudinal driving member 216 is connected to the adapter seat 208, and the longitudinal driving member 216 extends along the axis of the transmission rod 205. A vertical pressing assembly is arranged above the accommodating box 217, and the vertical pressing assembly includes a pressing seat 220, and the pressing seat 220 extends into the accommodating chamber 218 from the upper port of the accommodating box 217, and two vertical driving members 221 are installed at the upper end of the pressing seat 220. The above-mentioned longitudinal driving member 216 and the vertical driving member 221 can be an electric cylinder, a cylinder or an oil cylinder. The slicing mechanism of this embodiment includes a power motor 214 and a plurality of mounting shafts 211, and a connecting ear 210 is constructed at the lower part of each horizontal material guide barrel 201, and each mounting shaft 211 is rotatably connected to the corresponding connecting ear 210, and a synchronous pulley 212 and a cutting blade 213 are coaxially mounted on the mounting shaft 211, and the cutting blade 213 is located at the outlet end of the corresponding horizontal material guide barrel 201, and the output shaft of the power motor 214 is coaxially connected to one of the mounting shafts 211, and all the synchronous pulleys 212 are connected through a synchronous transmission belt 215.The working principle and advantages of this embodiment are as follows: After the potato to be sliced is filled into the accommodation cavity 218, the vertical driving member 221 is controlled to drive the pressing seat 220 to extend into the accommodation cavity 218, and the pressing seat 220 is controlled to always press on the uppermost layer of the potato; the power motor 214 of the slicing mechanism is controlled to act, so that it drives each cutting blade 213 to rotate; at the same time, the longitudinal driving member 216 is controlled to reciprocate longitudinally.

Moreover, multiple feeding mechanisms are used for slicing operations, further improving the slicing efficiency.
