Embodiment Construction

[0041] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0042] see figure 1 and image 3 , figure 1 It is a schematic diagram of the process flow of the present invention, image 3 It is the working flow diagram of the concentration unit and the refining unit of the present invention. The starch separation method of the present invention comprises the steps of pulverizing 101 raw materials, sieving 201, concentrating 301, refining 401, dehydrating 501, drying 601 and packaging finished products 701. After the raw materials are pulverized 101, sieved 201, they are transported into the concentrated 301 step In this step, the overflow 304 separated by the cyclone is directly discharged from the cyclone system, the underflow 302 enters the subsequent refining step 401 for further separation, and the underflow starch milk 403 finally obtained by the separation of the refining step is...

Abstract

The invention provides a starch separation method and a device. The method comprises the steps of grinding, screening, concentration, refining, dehydration, drying and packing, wherein the concentration step comprises a step for concentrating starch milk and a step of secondary washing, a multi-level swirler is adopted to separate juice, starch milk and sludge in a backflow washing way, and the secondary washing step comprises the following steps that: the discharged overflow is supplied to the screening step or the discharged overflow is re-separated or directly discharged. The starch processing method can reduce the energy consumption, improve the yam starch quality and the yield, and especially has the advantages that the water can be saved and the separated starch juice can be recycled when abnormality happens. The device by adopting the method is simple to operate, consumes less water and has high working efficiency.

Description

technical field [0001] The invention relates to a solid-liquid separation method and equipment, in particular to a manufacturing process and equipment for potato processed starch. Background technique [0002] At present, potato processing generally goes through the following process: cleaning of raw materials - crushing - screening - cyclone separation - dehydration - drying - packaging - finished products. Potatoes (mainly including sweet potatoes, cassava and potatoes) are first pre-treated and cleaned, and then enter the designated crushing facility. The raw materials are crushed into potato pulp and then sent to four-stage or multi-stage screening to initially separate the crude fibers. The remaining potato pulp is put into the cyclone separation process. During this process, the potato pulp is concentrated and refined, and finally the starch in it is separated from protein, fine fiber and other impurities to obtain refined starch milk, which is then subjected to vacuum...
