Preparation technology of potato whole powder

Abstract

The invention discloses a preparation technology of potato whole powder. The preparation technology comprises the steps of conveying a raw material by water flow, and then feeding the raw material to a cleaning and stone-removing procedure and a peeling procedure sequentially; after the raw material is treated by the peeling procedure, cutting the raw material into pieces; and feeding the cut raw material to subsequent working procedures of cooking, mashing, roller drying and film preparation, crushing and packaging sequentially. The raw material of the potato whole powder is one in purple sweet potatoes, sweet potatoes and purple potatoes, and the cut raw material pieces have the length of 70-100 mm; the purple potatoes are sliced after being cut into pieces, and the purple potato slices sequentially enter the subsequent working procedures of cooking, mashing, roller drying and film preparation, crushing and packaging; the purple potato slices have the thickness of 10-30 mm. After the preparation technology is adopted, the generality of the potato processing technology can be improved, and the combination of preparation technologies of different potato materials can be realized; therefore, the utilization rate of a whole powder device and the whole powder quality are improved, and the aims that one machine in a processing enterprise serves multiple purposes, and the products are diversified can be achieved.

Description

technical field [0001] The invention relates to the technical field of potato processing, in particular to a production process for purple potato, sweet potato, potato and purple potato whole powder. Background technique [0002] At present, the process technology of single production of potato flour has been widely used. Because purple potato, sweet potato, and purple potato have different raw material characteristics, they are also quite different from potato characteristics. Therefore, purple potato, sweet potato, and purple potato powder cannot be produced by using the technology of whole potato powder. [0003] Chinese patent document CN102697004A discloses a production method of purple sweet potato powder, fresh purple sweet potato is cleaned and peeled, cut into strips, color protection, rinsed, ripened, mashed, backfilled, dried, sieved, and finished, wherein the drying is Spin flash dry. In the above treatment process, the purple sweet potato is cut into strips a...

AI Technical Summary

Problems solved by technology

In the treatment process of the above-mentioned sweet potato powder, the peeled potato pieces are also sliced ​​or cut into strips. Slicing or strips will greatly increase the cut section of the raw material, so that the material on the section will be lost by washing, resulting in The dry matter, anthocyanins and natural pigments in the raw materials are lost in a large amount, and the unique properties of the raw materials cannot be maintained; at the same time, the above-mentioned whole powder production process is only for the production of sweet potatoes, and for purple potatoes, purple potatoes or potatoes, due to the characteristics of raw materials There is a big difference from sweet potatoes, so it is difficult to realize the whole powder processing of multiple potato raw materials with one set of equipment
