Description

Device to purify salt, to make bamboo salt or baked salt by drying and heat treatment of Microwave.

In general, salts are broadly classified into sun salts, preparation salts, and tablet salts. In recent years, impurities in the salt are not beneficial to the human body, and salt that is not drained by the salt has a bitter taste, so it is not intended to be used in cooking. However, the harmful to the human body is not the water itself, but because it is an impurity contained in the water, it is possible to remove the impurities at high temperatures, to prepare them with bamboo salt, or to dissolve the salt and to prepare salt to eat through salt drying.

.

The present invention is two types.

First, in the form of roasted salt (less than 400 ℃), baked salt (more than 400 ℃), melted salt (more than 900 ℃) using a micro wave, the impurities of the salt through dry melting from 200 ℃ to 1,400 ℃ It is to remove impurities quickly and easily.

Second, the existing wood, coal, etc., or the resistance heating directly to the salt in bamboo by heating the micro-wave shortens the production time of bamboo salt, using the micro-wave salt 200 ℃ ~ 1,400 ℃ to dry the device.

Salt treatment apparatus of the present invention for achieving the above object can be divided into two.

First, it is a device that dissolves salt continuously to crush the melted salt to low temperature of the tank. It consists of one opening and one outlet, and irradiates the crucible with a microwave to detect the temperature in the thermocouple, if it is molten, opens the outlet and then circulates the device receiving molten salt to circulate the temperature inside the tank. It is chilled and crushed by thermal shock. When many impurities of hot salt are gasified, micro gas plasma or electric arc plasma and LPG, LNG and city gas are used to burn the exhaust gas to the internal gas outlet.

The chamber may be connected to a control unit for controlling the microwave irradiation output and temperature.

The chamber may be provided with a temperature sensor.

Toxic gas may be burned in the chamber using microwave plasma, arc plasma, or LPG, LNG, or city gas.

The crucible of the chamber is made of Al 2 O 3, ZrO 2, SiO 2, Mgo, and SiC, and may be mixed with these compounds.

The insulation of the chamber may be a board, a blanket, or a vacuum molded product containing Al2O3 + SiO2, Al2O3 + ZrO2 + SiO2, CaO + SiO2 + Al2O3, SiO2, and the like, or brick, castable, or firebrick.

The chamber has an inlet for continuously inputting salt, and an outlet for discharging continuously melting salt.

The chamber may be installed with a tank having a water circulation device that can break the melting salt with a thermal shock.

Second, put salt-filled bamboo in a large crucible, plug the stopper with mud kneaded in water, and then place it horizontally in the crucible, irradiate Mircro waves and fill with nitrogen gas, and burn the gas from the exhaust to burn toxic gas. Remove it. It is configured to use temperature sensor and insulation.

The chamber may be connected to a control unit for controlling the irradiation output and temperature of the microwave.

The chamber may be a temperature sensor for sensing the temperature.

The crucible of the chamber is made of Al 2 O 3, ZrO 2, SiO 2, Mgo, and SiC, and may be mixed with these compounds.

The heat insulating material of the chamber, the heat insulating material may be Al 2 O 3 + SiO 2, Al 2 O 3 + ZrO 2 + SiO 2, CaO + SiO 2 + Al 2 O 3, Board, Blanket or vacuum-formed products and brick or castable, refractory bricks containing.

The chamber may insulate all of the upper surface and the bottom surface.

The chamber may put N2, Ar gas into the chamber to prevent burning of the bamboo of the crucible.

The chamber may also fill the mud between the bamboo and the bamboo.

The chamber may use a lid to prevent burning of bamboo.

As described above, the impurities of the salt are treated at a high temperature, thereby producing the powder salt which is beneficial to the human body continuously.

The production of bamboo salt in the traditional method takes a long time, so it is possible to prepare bamboo salt in a short time using a micro wave, and the salt may be heat-treated to 200 ° C. to 1,400 ° C. to remove impurities.
