All reasonable variations and combinations that are included within the scope of the inventive concept fall within the scope of the present application.
The application discloses automatic equipment for crushing and separating fresh sweet potatoes, which is a set of production line suitable for modern industrial production, wherein the harvesting time of the sweet potatoes is related to varieties, planting time and planting areas, and is generally about 10 months. Since fresh sweet potatoes have a fixed harvesting time, a large amount of fresh sweet potatoes must be harvested and stored in the harvesting Ji Jiehui, and must be processed in a short time, but the market demand for sweet potato starch is about the same in each period of time each year, thus bringing about a certain contradiction. In order to solve the problem, the sweet potato starch automatic production line of the application firstly designs an intermittent production line procedure, wherein the intermittent production line is used for intensively carrying out procedures of cleaning, crushing, fiber separation, pulp extraction and separation on fresh sweet potatoes purchased in a harvesting season to obtain separated starch pulp, a starch buffer tank for storing concrete materials is arranged in the middle of the starch buffer tank, and then the rest continuous production line is used for continuously carrying out procedures of adding water, stirring and sedimentation in the starch buffer tank, purifying, drying, packaging the obtained starch and the like.
Specifically, the intermittent production line comprises a sweet potato cleaning mechanism, a sweet potato crushing mechanism, a primary fiber separating mechanism, a secondary fiber separating mechanism, a primary starch extracting mechanism, a secondary starch extracting mechanism and a starch separating mechanism. The continuous production line includes a starch settling mechanism and also includes a control mechanism that controls the operation of all application processes from cleaning to settling, as shown in fig. 1.
The specific constitution of each mechanism is described below:
(1) Cleaning section
The cleaning mechanism 1 is responsible for cleaning the purchased fresh sweet potatoes by washing and removing sundries such as stones. The field device is shown in fig. 2, and comprises a medium water pipe 1-1 and a clear water pipe 1-2, wherein the medium water pipe and the clear water pipe are connected with a sweet potato cleaning mechanism through a pipeline, fresh sweet potatoes are conveyed into a fresh sweet potato dry cleaner 1-4 through a loading vehicle 1-3 and dry cleaned, the fresh sweet potatoes after dry cleaning enter a first water-washing screw conveyor 1-5, a water pipe is connected above the first water-washing screw conveyor, the fresh sweet potatoes are conveyed upwards on the water pipe and are washed in the conveying process, residues and sewage after water washing flow downwards to a first belt conveyor 1-6 and are manually collected, the first water-washing screw conveyor sends sweet potatoes into a hydraulic stone remover 1-7, the water pipe is connected above the hydraulic stone remover, the sweet potatoes enter a roller stone remover 1-8 after stone removal, the stones enter a lifter 1-9 from a lower outlet, and the stones are manually collected after lifting; after stone removal by the roller, the sweet potatoes sequentially pass through two washing procedures of a second washing screw conveyor 1-10 and a third washing screw conveyor 1-11 and are sent to a first-stage disintegrator by the screw conveyor.

Wherein the cleaning mechanism 1 is carried out by two identical parallel production lines, only one of which is taken as an example in fig. 2, and the amount of sweet potatoes processed by the two production lines is about 10 ten thousand jin/hour. The section is required to clean purchased fresh sweet potatoes by water washing and remove sundries such as stones, as shown in fig. 2, water pipes obtained by mixing reclaimed water and clear water are respectively conveyed to a first water washing screw conveyor, a hydraulic stone removing machine, a roller stone removing machine, a second water washing screw conveyor and a third water washing screw conveyor, and the purpose of thoroughly cleaning and removing stones is achieved through a three-channel water washing process and a roller and hydraulic two-stage composite stone removing process. However, in actual production, the fresh sweet potatoes are collected from different producing places, the harvesting seasons, the surface dryness, the transportation conditions and the like, the soil and stone content of the fresh sweet potatoes greatly fluctuates, and obvious water waste is caused in the early stage due to unreasonable process design. The water consumption is reduced, so that insufficient cleaning is caused, and the subsequent starch quality is greatly influenced. Therefore, when different sweet potatoes in different batches are washed and stoned in a workshop, the mud content and the stony content of the sweet potatoes, the water pressure parameters of each stage during the stoning by water and the stoning effect by water are recorded, the recorded big data are analyzed, reasonable technological parameters are selected from the recorded big data, and the following determination modes are selected through analysis:
five water pressure parameters are set, and the water pressure of the first water-washing screw conveyor is P 1 The hydraulic pressure of the hydraulic stoner is P 2 The water pressure of the roller destoner is P 3 The water pressure of the second water-washing screw conveyor is P 4 The water pressure of the third water-washing screw conveyor is P 5 。
Wherein P is 1 Fixed at 0.3MPa, P 4 And P 5 Setting and adjusting according to the mud content, specifically:
k 1 the value range of the coefficient of the two-pass water washing is 6-8 k 2 The coefficient of three water washes is 5-6, G is the mud content of sweet potatoes, and the mud content of sweet potatoes in different batches and places is approximately 2% -4.5%.
For example, for sweet potato with a mud content of 3%, P 1 Selecting 0.3MPa, P 4 Can select 0.18 MPa, P 5 0.09 MPa may be selected. For sweet potato with mud content of 4%, P 1 Selecting 0.3MPa, P 4 Can select 0.22 MPa, P 5 0.11 MPa may be selected. By adopting the water washing mode, on the premise of fully ensuring the water washing effect, the water consumption is reduced, the cost is saved, and the energy conservation and the environmental protection are facilitated.
