Surface dehydrating method of cleaned Chinese chestnuts

Abstract

The invention discloses a surface dehydrating method of cleaned Chinese chestnuts. The method comprises the following steps that cleaned Chinese chestnuts are put in a rotating cylinder, a bamboo fiber inner lining is arranged on the inner wall of the rotating cylinder, a fixing cylinder body is in sleeving connection to the outer part of the rotating cylinder coaxially, water-permeable holes areuniformly distributed in the cylinder wall of the rotating cylinder, and the rotating cylinder is rotated, so that the Chinese chestnuts slide relative to the bamboo fiber inner lining, the moisture on the surfaces of the Chinese chestnuts can be wiped out through the bamboo fiber inner lining, the moisture adsorbed by the bamboo fiber inner lining is swung to the inner part of a fixing cylinder through the water-permeable holes under the action of centrifugal force, and finally, the moisture flows out from one end of the fixing cylinder. According to the surface dehydrating method, the cleaned Chinese chestnuts can be subjected to centrifugal dehydrating.

Description

technical field [0001] The invention belongs to the technical field of chestnut immediate treatment, and relates to a method for surface dehydration of washed chestnuts. Background technique [0002] Chestnut is known as the "King of Dried Fruits" and is very popular because of its rich nutritional value. The annual output of chestnuts in the world has been increasing year by year, and the annual output in my country has reached nearly one million tons. Although the output is large, the preservation of chestnuts is a difficult point. If you are not careful, the chestnuts will become moldy and deteriorate. [0003] After the chestnut is picked, due to the fungus, bacteria, insect eggs and high water content in it, the chestnut is very prone to insects, mildew and deterioration. It can be sterilized with salt water first, and then the surface of the chestnut is cleaned with salt water to remove the chestnut. Salt on the surface. [0004] However, there are following difficul...

Problems solved by technology

[0004] However, there are following difficulties in removing water from the surface of chestnuts: 1. When using centrifugal removal, due to the need for a higher number of revolutions, the chestnuts can be rotated with the drum in t
