Improved method for bamboo salt production

Abstract

An improved method for bamboo salt production takes eight measures as follows: firstly, baking is changed from four different temperature stages to two different temperature stages; secondly, the baking equipment is converted from a reaction kettle to a firewood stove with grates; thirdly, raw materials and the lengths of bamboo pipes are limited; fourthly, the water content of to-be-processed salt is limited; fifthly, no fire-resistant pot is sleeved outside the bamboo pipe; sixthly, yellow mud is only used for sealing the bamboo pipes in the activation stage, and yellow bamboo salt at the upper end of a salt rod is removed; seventhly, no bamboo leaf or bamboo shell is filled in openings of the bamboo pipes, and bamboo vinegar is not mixed in salt; eighthly, the bamboo pipes are placed in a partition manner in a stove by division bars. Through the adoption of the improved measurements, the placement quantity of the bamboo pipes in the stove is increased, the yield is improved, the salt heat treatment is uniform, the quality of the bamboo salt is improved and stable, and after the liquefaction and distillation stages of the salt are removed, the highest processing temperature is lower than 835 DEG C, the thermal loss is low, the production period is short, the raw materials do not comprise bamboo leaves, bamboo shells and bamboo vinegar, the bamboo salt is not polluted, and the taste is good.

Description

technical field [0001] The invention relates to an improvement of the deep processing technology of table salt, in particular to an improved method for producing bamboo salt capable of removing impurities and heavy metal ions in the table salt, trace elements incorporated into bamboo and turpentine and other components beneficial to the human body. Background technique [0002] In ancient my country's "Compendium of Materia Medica", there is a description of the medicinal use of roasted salt. Bamboo salt has a relatively long history of production and application in South Korea. It is said that the Buddhist circles have been inspired by alchemy and the theory of yin and yang gossip, and handed down the essentials of the production method of bamboo salt. Bamboo salt has only been produced in my country for more than ten years. , South Korea's traditional methods combined with self-explored new experience, has gone through more than ten years of enterprise production, and gradu...

Problems solved by technology

[0003] CN 1088983C announcement "bamboo salt roasting and melting smoking method" uses a reactor as a special device for roasting and melting smoking. Because the roasting and melting chamber is a spherical space, the vertical bamboo tubes are arranged unevenly, easy to dump, difficult to control temperature, and difficult to heat. Uniform, unstable quality, unable to quickly put in and take out the bamboo tube; after the salt is heated, it goes through four heat treatment stages of dehydration, combustion, melting and distillation, and the temperature rises to 1100-1300°C, with long production cycle and high energy consumption; In the four stages of heating, the yellow mud seals the mouth of the bamboo tube from the initial dehydration stage, and the muddy water leaks to the bottom of the bamboo tube, and the color, taste and impurities of the yellow mud enter the bamboo salt, affecting the quality of the bamboo salt.

[0004] CN102578548A announces " a kind of preparation technology of nutritious bamboo salt ", adopts the baking mode of putting bamboo tube in the refractory tank with cover or uncovered, and the refractory tank with big volume takes up the discharge space in the furnace more, affects the production of bamboo salt. The ineffective heat absorption of the refractory tank increases the heat consumption, which affects the heat treatment effect of the bamboo tube and the salt in it, and the bamboo tube cannot be ashed but can only be carbonized, and the charcoal of the carbonized bamboo tube is not easy to separate from the salt on the surface of the salt rod; / 5 is filled with salt to be processed, the top 1 / 5 is filled with bamboo leaves, and then the bamboo tube is sealed with yellow mud and then baked, which will cause the bamboo leaves to be dry-distilled in the isolated air, resulting in black charcoal and burnt smoke, which will pollute the salt. Affect the quality of bamboo salt

[0005] The "preparation method of bamboo salt" of CN100374040C announcement also adopts putting bamboo tube in the refractory tank, and also fills the yellow mud in the gap between bamboo tube and refractory tank, takes up the space in the furnace big, and the invalid heat absorption is more High heat consumption; after the bamboo tube is filled with salt, it is filled with bamboo husks instead of bamboo leaves, and there is also the problem that the black charcoal and burnt smoke after the carbonization of bamboo husks will pollute the bamboo salt; the salt to be processed is also mixed with bamboo Vinegar, bamboo vinegar is highly acidic, which will pull the bamboo salt that has been converted from acidic ordinary table salt to alkaline back to acidic salt, and lose the good quality of bamboo salt

In addition, the burnt smoke (oil) smell of bamboo vinegar is very strong, which seriously pollutes bamboo salt.

[0006] The baking temperature of the above-mentioned three patents all reaches a maximum of 1300°C. The technical treatment of melting the salt into a liquid state and then distilling is energy-consuming, time-consuming, and the loss of salt is large.
