Problems solved by technology

If alum is not added, the sweet potato starch cannot be processed into smooth and chewy vermicelli, and the vermicelli produced in the vermicelli making step is easy to break into crushed vermicelli; the frozen vermicelli is also easily broken into crushed vermicelli after melting , and the taste is not good

Embodiment 1

[0010] Embodiment one: a kind of production process of sweet potato starch vermicelli, the sweet potato of harvest is processed by conventional cleaning, crushing production steps and then enters the screening and sedimentation production step. Use 90-mesh screen, 120-mesh screen, and 250-mesh screen to filter three times in turn; the starch suspension filtered with 250-mesh screen is deposited in the sedimentation tank for 8-10 hours; the upper and lower layers are formed in the sedimentation tank. The upper layer is liquid, and the lower layer is sweet potato starch that is precipitated together, and the upper liquid is released; the starch that is precipitated together is taken out, put into a container and stirred with water to form a starch suspension, and the starch suspension at this time is screened with a 300-mesh screen. Filtration, the filtered starch suspension is precipitated for 8-10 hours and then enters the conventional starch drying step; after conventional pul...

Embodiment 2

[0011] Embodiment two: a kind of production process of sweet potato starch vermicelli, the sweet potato of harvest is processed by conventional cleaning, crushing production steps and then enters the screening and precipitation production step. The specific process is: after adding water to the sweet potatoes after the crushing, Use 90-mesh screen, 120-mesh screen, and 250-mesh screen to filter three times in turn; the starch suspension filtered with 250-mesh screen is deposited in the sedimentation tank for 8-10 hours; the upper and lower layers are formed in the sedimentation tank. The upper layer is liquid, and the lower layer is sweet potato starch that is precipitated together, and the upper liquid is released; the starch that is precipitated together is taken out, put into a container and stirred with water to form a starch suspension, and the starch suspension at this time is screened with a 300-mesh screen. Filtration, the filtered starch suspension is precipitated for ...

Embodiment 3

[0012] Embodiment three: a kind of production process of sweet potato starch vermicelli, the sweet potato of harvest is processed by conventional cleaning, crushing production steps and then enters the screening and sedimentation production step. Use 90-mesh screen, 120-mesh screen, and 250-mesh screen to filter three times in turn; the starch suspension filtered with 250-mesh screen is deposited in the sedimentation tank for 8-10 hours; the upper and lower layers are formed in the sedimentation tank. The upper layer is liquid, and the lower layer is sweet potato starch that is precipitated together, and the upper liquid is released; the starch that is precipitated together is taken out, put into a container and stirred with water to form a starch suspension, and the starch suspension at this time is screened with a 300-mesh screen. Filtration, the filtered starch suspension is precipitated for 8-10 hours and then enters the conventional drying, pulping, vermicelli making and o...

Abstract

The invention discloses a sweet potato starch noodle production technology, which comprises the following steps: washing, grinding, screening and precipitating, drying starch, pulping, producing noodles, cooling, freezing, deicing and drying noodles, thus obtaining the finished sweet potato noodle product; the screening and precipitation steps comprise the following substeps: adding a proper amount of water into the ground sweet potato, and filtering sequentially through a 90-mesh screen, a 120-mesh screen and a 250-mesh screen; precipitating the filtered starch suspension liquid for 8-10 hours; and then placing the precipitated starch into a container, adding water and stirring to form starch suspension liquid, then filtering through a 300-mesh screen, and precipitating the filtered starch suspension liquid for 8-10 hours for later use. According to the sweet potato starch noodle production technology, smooth and chewy sweet potato noodles can be produced without addition of potassium alum, and are unlikely to be broken during the production process.

Description

technical field [0001] The invention relates to a production process of vermicelli, in particular to a production process of sweet potato starch vermicelli. Background technique [0002] Alum is a kind of sulfate with water molecules. Because it can gather and disperse, people have used it for many years when making sweet potato vermicelli. However, scientific research has found that because alum contains a large amount of aluminum ions, excessive intake will affect the body's absorption of iron, calcium and other components, and even damage the brain nerves, especially for children and the elderly. Aluminum itself is easy to accumulate in the human body. For example, it may accumulate in the brain, kidney, liver, spleen and other organs. If it accumulates in the brain, it will easily cause symptoms such as Alzheimer's, memory loss, and mental decline. Therefore, some nutrition experts suggest that we should try to eat less food containing alum. In this regard, the Nationa...
