Embodiment 1

[0080]The specific process of producing whole potato powder by using the raw sweet potato powder production system provided by the present invention is as follows: the sweet potato enters the mechanical peeling unit 2 for peeling after the cleaning unit 1 cleans the surface sludge, and then enters the slicing unit 3 for slicing. , the slices enter the ice-temperature beating unit 4, mix the slices with 4°C ice water, beat with a crushing machine, and pulverize into a sweet potato slurry; the sweet potato slurry enters the first filter unit 5, and is separated into the first filtrate and the first filter residue; The first filter residue enters the cellulose enzymatic hydrolysis unit 6, and is further crushed with a masher, and is treated with cellulase at 0.3wt% of the first filter residue weight for 4 hours, squeezed and filtered to obtain the second filtrate and the second filter residue; After the first filtrate and the second filtrate are combined, enter the colloid mill un...

Embodiment 2

[0082] The specific process of producing whole potato powder by using the raw sweet potato powder production system provided by the present invention is as follows: the sweet potato enters the mechanical peeling unit 2 for peeling after the cleaning unit 1 cleans the surface sludge, and then enters the slicing unit 3 for slicing. , the slices enter the ice-temperature beating unit 4, mix the slices with 1°C ice water, beat with a crushing machine, and pulverize into sweet potato slurry; the sweet potato slurry enters the first filter unit 5, and is separated into the first filtrate and the first filter residue; The first filter residue enters the cellulose enzymatic hydrolysis unit 6, and is further crushed with a masher, and is treated with cellulase at 0.5 wt% of the weight of the first filter residue for 4 hours, squeezed and filtered to obtain the second filtrate and the second filter residue; After the first filtrate and the second filtrate are combined, enter the colloid ...

Abstract

The invention relates to a sweet potato raw whole flour, a production method and a production system thereof and a mechanical peeling unit. The production method comprises the following steps: firstly, mechanically peeling sweet potatoes, slicing the peeled sweet potatoes, pulping the slices in ice water at 0-4 DEG C, and filtering to obtain a first filtrate and a first filter residue; mashing thefirst filter residue, adding cellulase for enzymolysis, and then extruding and filtering to obtain a second filtrate and a second filter residue; mixing the second filtrate and the first filtrate, treating by a colloid mill, and performing microwave vacuum drying at 40-60 DEG C to obtain the first sweet potato raw whole flour; and performing microwave vacuum drying of the second filter residue, and carrying out superfine grinding to obtain the second sweet potato raw whole flour. High temperature is avoided in the whole process, so that gelatinization of the sweet potato raw whole flour in the production process is avoided; adding the cellulase into the filter residue for enzymolysis, carrying out superfine grinding after microwave vacuum drying, filtrate is treated by a colloid mill, andthe fineness of the sweet potato raw whole flour is improved.

Description

technical field [0001] The invention relates to the field of food processing, in particular to raw sweet potato powder, a production method, a production system and a mechanical peeling unit. Background technique [0002] Sweet potato has good nutritional value and is a high-quality food raw material. At present, many enterprises use sweet potatoes to prepare sweet potato powder as food raw materials or auxiliary materials. Sweet potato flour includes all dry matter except sweet potato skin. Unlike potatoes, the research and application of potato flour in food production and processing in my country is relatively mature, but the research and application of sweet potato flour is not perfect. Sweet potato flour includes cooked whole flour and raw whole flour, whether it is cooked whole flour or raw whole flour, it can be used to process sweet potato steamed bread, sweet potato bread, sweet potato cake, sweet potato ice cream, sweet potato noodles, sweet potato vermicelli, swe...
