Bamboo powder salt manufacture method and bamboo salt got as a result of this

Abstract

The present invention relates to a method for manufacturing powdered bamboo salt in which effective components of bamboo are adsorbed onto salt during a process in which salt harvested from a salt field absorbs moisture from the air when humidity is high and leaches out the absorbed moisture along with brine when humidity is low, thereby reducing the bitterness contained in the salt; consequently, it takes several years to obtain dry salt from which brine has been removed in this manner. The present invention relates to a method for manufacturing powdered bamboo salt in which the bitterness of the salt is reduced by spraying bamboo distillate extracted by a double boiler onto the salt, adsorbing the effective components contained in the bamboo onto salt of different sizes, and drying it with heat from a double boiler. To this end, the present invention comprises: a coarse salt initial drying step (500) in which hot air (422) at 90°C to 100°C is injected into the interior of a first tank (100) into which coarse salt (600) is introduced to dry the moisture content on the surface of the coarse salt (600) to 1% or less; and the interior of the first tank (100) A first bamboo distillate spraying adsorption step (510) in which bamboo distillate (411) is sprayed through a distillate spraying device (410a) to increase the moisture content of the surface of coarse salt (600), which has been dried to a moisture content of 1% or less in the first coarse salt spraying adsorption step (500), to 10% to 15%; a first drying step (520) by hot water bath air in which hot water bath air (422) at 90°C to 100°C is injected into the interior of the first tank (100) to dry the moisture content of the surface of coarse salt (600), which has been increased to a moisture content of 10% to 15% in the first bamboo distillate spraying adsorption step (510), to 1% or less; and a coarse salt dried to a moisture content of 1% in the first tank (100) through the first drying step (520) by hot water bath air A fine salt crushing step (530) in which coarse salt (600) is crushed into fine salt (601) with a size of 1 mm to 3 mm or less and introduced into the interior of the second tank (200);A second bamboo distillate injection adsorption step (540) in which bamboo distillate (411) is injected into the interior of the second tank (200) through a distillate injection device (410b) to increase the moisture content of the surface of the fine salt (601), which has been maintained at a moisture content of 1% or less in the fine salt crushing step (530), to 7% to 10%; a second drying step (550) by hot water bath air in which hot water bath air (422) at 90°C to 100°C is injected into the interior of the second tank (200) to dry the moisture content of the surface of the fine salt (601), which has been increased to a moisture content of 7% to 10% in the second bamboo distillate injection adsorption step (540), to 1% or less; and a second drying step (550) by hot water bath air in the second tank (200) in which the moisture content is... A powdered salt grinding step (560) in which fine salt (601) dried to 1% is ground into powdered salt (602) with a size of 0.2mm to 1mm or less and introduced into the interior of a third tank (300); a bamboo distillate spraying third adsorption step (570) in which bamboo distillate (411) is sprayed into the interior of the third tank (300) through a distillate spraying device (410c) to increase the moisture content on the surface of the powdered salt (602), which has a moisture content of 1% or less maintained in the powdered salt grinding step (560), to 5% to 7%; and a water bath hot air (422) at 90°C to 100°C is injected into the interior of the third tank (300) to increase the moisture content on the surface of the powdered salt (602), which has a moisture content of 5% to 7% in the bamboo distillate spraying third adsorption step (570), to 1% The present invention relates to a method for manufacturing powdered bamboo salt and powdered bamboo salt manufactured by the same method, characterized by comprising: a third drying step (580) by a hot water bath to dry to a lower level; and a powdered bamboo salt completion step (590) in which powdered bamboo salt (700), which has been dried to a state where the moisture content of the surface of the powdered salt (602) is 1% or less after passing through the third drying step (580) by the hot water bath in the third tank (300), is discharged out of the tank.
