Walnut kernel peeling process

Abstract

The invention discloses a walnut kernel peeling process. According to the walnut kernel peeling process, steaming and peeling are separated, and a soaking process is added and a rotary drum is used for realizing continuous production; the walnut kernel peeling process is suitable for a flow production line; a steaming rotary drum is used for realizing even steaming, steam is used for heating and the problems of walnut kernel floating and walnut kernel going out upwards due to the rotation of the rotary drum are solved by virtue of steam injection directions; a water-steam mixture is used for peeling; above 20-30% of water resources can be saved; the steam injection directions swing back and forth within a certain angle; peeling by use of a water gun is simulated, so that the walnut kernels can be turned over and peeled sufficiently, and the peeling effect is uniform and consistent and far better than that of artificial water gun peeling, and the peeling treatment rate is above 99.5%; meanwhile, the labor is greatly saved, and more than 95% of labor can be saved; soaking water is used for peeling or supplied to a steaming water tank by use of a water circulating system; the peeling water can be further applied peeling; only when the steaming water is high in color concentration, the water is discharged; the water consumption amount for treating 1 ton of walnut kernels is reduced to 0.6 ton now from 1.2 tons in the past, and the water is saved.

Description

technical field [0001] The invention relates to a food processing technology, in particular to a walnut kernel peeling technology, which belongs to the field of food processing. Background technique [0002] Medical research has proved that the phospholipids in walnuts have a good health care effect on the brain nerves; walnut oil contains unsaturated fatty acids, which can prevent and treat arteriosclerosis; walnut kernels contain zinc, manganese, chromium and other indispensable trace elements for the human body. In recent years, walnut milk beverages and walnut foods processed from walnut kernels are in line with the trend of consumers pursuing health and nutrition because of their natural, nutritious and health-care properties. [0003] When walnuts are further processed, it is necessary to remove the thin outer skin of the walnut kernel to remove the bitter taste. At present, the walnut kernel peeling technology is relatively backward. Some people use the method of soa...

Problems solved by technology

⑥It can only be steamed and cooked in one pot and one pot

[0005] The disadvantages of this treatment process are: ①. Manually pouring one box after another into the kettle has a time difference of 2 to 5 minutes for cooking walnut kernels. The cooking time in the cooking tank is long, and vice versa. If it is overcooked, the walnut kernels will be boiled on high heat, resulting in waste and loss; some walnut kernels will not be cooked enough, which will make it difficult to wash off when peeling.

② When cooking walnut kernels, in order to cook evenly, the stirring should be turned on, and the walnut kernels will be damaged during the stirring process, resulting in waste of walnut kernels

③ After
