Water chestnut de-hulling device

Abstract

The invention relates to a water chestnut de-hulling device, which comprises a rack. Two rotating shafts are arranged on the rack in parallel, two gears are fixed on each rotating shaft, two paralleled chains are wound on the corresponding gear between the two rotating shafts, a plurality of feeding moulds are fixed between the two chains at intervals, a groove to accommodate the water chestnut is arranged on the feeding moulds, and two hold-down strips used to hold down two sides of the water chestnut are respectively arranged on two sides above the groove; an upright column is arranged on the outer side of the chain on the rack, and a hylum cutting knife which can move up and down is arranged on the upright column, the position of the hylum cutting knife is opposite to the position of the groove, and at least a hull breaking knife is arranged at the rear side of the hylum cutting knife on the upright column. When the device is put into operation, firstly the hylum cutting knife cuts the hylum of the water chestnut to rift cut the hylum; secondly the hull breaking knife cuts an opening on the water chestnut to break the wrapping structure of the tough closed hull of the water chestnut; and the nut can be quickly taken out, thereby reducing the de-hulling difficulty and improving the production efficiency.

Description

technical field [0001] The invention relates to a shelling device for fruit shells, in particular to a shelling device for water chestnuts. Background technique [0002] Water chestnut is the fruit of a freshwater plant water chestnut, which is widely distributed in the Yangtze River Basin and the south. Water chestnut has high nutritional value and is rich in starch, glucose, protein, vitamin B and C, water chestnut, β-sitosterol, Calcium, phosphorus, iron and other ingredients. There are many varieties of water chestnut, such as two-cornered water chestnut, red water chestnut, green water chestnut, four-cornered water chestnut, and wonton water chestnut without horns. The water chestnut is covered by a hard shell, and the nuts are wrapped in the shell. Every 100 grams of the nuts contain 3.6 grams of protein, 0.6 grams of vitamins, 0.5 grams of fat, 0.49 grams of phosphorus, 0.9 grams of calcium, and 0.027 grams of iron. , carotene 0.01 g, etc., its nutritional value is ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, in order to take out the water chestnut nuts, manual shelling is required. Because the shell of water chestnut is tough and has thorn-like sharp corners, manual shelling is expensive and laborious. Generally, a worker can only manually peel 2-3Kg per hour. water chestnut kernels, the efficiency is extremely low
