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 separat...
