Embodiment 1

[0016] 1. Select the raw potatoes of the year to remove the spoiled and mildewed parts, wash and peel them.

[0017] 2. Then cut the raw materials into shreds, the diameter of which is 0.8 cm, and dehydrate them at a temperature of 5°C.

[0018] 3. After dehydration, place the raw materials in an ultrasonic treatment environment for pretreatment, with an ultrasonic power of 800w / kg, each treatment time is 3min, the interval between each ultrasonic treatment is 5s, and the number of ultrasonic treatments is 4 times.

[0019] 4. Add twice as much water to the pretreated potato material and send it into the beater for stirring and beating to obtain evenly dispersed potato slurry.

[0020] 5. The potato slurry is transported into the twin-screw extruder through the feed liquid pump for pregelatinization extrusion dehydration treatment. The degree of pregelatinization of the fresh potato material slurry in the twin-screw extruder is related to the pregelatinization time and pressur...

Embodiment 2

[0023] 1. Select the raw potatoes of the year to remove the spoiled and mildewed parts, wash and peel them.

[0024] 2. Then cut the raw material into shreds, the wire diameter is 1.0 cm, and carry out dehydration treatment at a temperature of 5°C.

[0025] 3. After dehydration, put the raw materials in an ultrasonic treatment environment for pretreatment, the ultrasonic power is 1000w / kg, the treatment time is 3 minutes each time, the interval between each ultrasonic treatment is 10s, and the number of ultrasonic treatments is 4 times.

[0026] 4. Add twice as much water to the pretreated potato material and send it into the beater for stirring and beating to obtain evenly dispersed potato slurry.

[0027] 5. The potato slurry is transported into the twin-screw extruder through the feed liquid pump for pregelatinization extrusion dehydration treatment. The degree of pregelatinization of the fresh potato material slurry in the twin-screw extruder is related to the pregelatiniz...

Embodiment 3

[0029] 1. Select the raw potatoes of the year to remove the spoiled and mildewed parts, wash and peel them.

[0030] 2. Then cut the raw material into shreds, the wire diameter is 1.0 cm, and carry out dehydration treatment at a temperature of 5°C.

[0031] 3. After dehydration, place the raw materials in an ultrasonic treatment environment for pretreatment, with an ultrasonic power of 900w / kg, each treatment time is 3min, the interval between each ultrasonic treatment is 7s, and the number of ultrasonic treatments is 5 times.

[0032] 4. Add twice as much water to the pretreated potato material and send it into the beater for stirring and beating to obtain evenly dispersed potato slurry.

[0033] 5. The potato slurry is transported into the twin-screw extruder through the feed liquid pump for pregelatinization extrusion dehydration treatment. The degree of pregelatinization of the fresh potato material slurry in the twin-screw extruder is related to the pregelatinization time...

Abstract

The invention relates to a method for processing potato powder, comprising the following steps: 1) pretreatment; 2) powder extraction treatment; 3) powdering, wherein potato is firstly pretreated, notonly thoroughly cleaned, but also plant cell walls, microbial cell membranes, organelles and the like of the potato is affected by ultrasonic wave to be mechanically damaged, thereby realizing the effect of improving extraction efficiency of certain components; by further adjusting process parameters of gelatinization process, the process is reduced, high-quality potato raw material powder is obtained, storage problems of fresh potatoes are solved, and possible waste of fresh potato resources due to improper storage of fresh potato is avoided; a product obtained by the method for processing potato powder can be used as a staple food raw material, or can be used as a food processing excipient, a food additive or a filling aid for health care foods and medicines, and can also be used as a chemical raw material.

Description

technical field [0001] The invention relates to the field of agricultural and sideline product processing, in particular to a method for processing potato flour. Background technique [0002] Potatoes are also known as potatoes, yams, yams, yam eggs, etc. Potatoes are the fourth major crops in the world after wheat, rice and corn, and are important raw materials for starch production. Since the 1960s, the growth of potato-producing areas in developing countries has exceeded that of other food crops. It has brought great hope for maintaining global food security. China's potato planting area and total output both rank first in the world. The planting area exceeds 100 million mu, and the per unit yield exceeds 1,200 kilograms, accounting for 20% of the world's total output. Compared with other crops, potatoes are used as a food, vegetable, feed, and industrial raw material. Potato seed potatoes and various processed products have become an important part of the global econom...
