Expanded bamboo salt producing method

Abstract

An expanded bamboo salt producing method comprises the following seven steps: 1, preparing materials, including bamboo material selection, bamboo barrel production, and preparation of salt to be processed and pine wood as fuel; 2, filling the salt into bamboo barrels; 3, selecting a roasting furnace; 4, charging, including substeps of examining and cleaning the furnace before charging, installing a grate and charging the bamboo barrels; 5, igniting, roasting, and dewatering the salt; 6, expanding the dewatered salt; and 7, postprocessing the expanded bamboo salt. Only through two hot processing stages of dewatering and expanding, the expanded bamboo salt produced by the expanded bamboo salt producing method is heated to the maximum temperature 835 DEG C; after repeatedly expansion for 3-5 times, the vast majority of heavy metal ions can be removed, a majority of beneficial components in the bamboo and pine resin can be fused, and organic impurities in edible salt can be burned out; the expanded bamboo salt producing method is low in energy consumption, short in production cycle, little in salt loss, high in yield of the bamboo salt and low in production cost; and sold bamboo salt products are low in price, can be easily accepted by consumers and have a wide consumer group.

Description

technical field [0001] The invention relates to a deep processing method of table salt, in particular to a production method of taking table salt into bamboo tubes, removing heavy metal ions during high-temperature cracking, that is, puffing, and inhaling beneficial ingredients in bamboo and rosin. Background technique [0002] In "Compendium of Materia Medica", it is recorded that roasted table salt is used for medicinal purposes, but no specific preparation method has been handed down. It is said that more than a thousand years ago in South Korea, people of insight in the religious circles, inspired by alchemy and the theory of yin and yang gossip, summed up a set of bamboo salt production methods, intermittently and sporadically. spread. More than 50 years ago, we saw the phenomenon of baking bamboo salt in large iron pots or buckets in South Korea. The production of bamboo salt was still in the original irregular stage. my country's bamboo salt production started more ...

Problems solved by technology

Fifty years ago in South Korea, we saw the phenomenon of baking bamboo salt in large iron pots or buckets. Bamboo salt production is still in the original irregular stage.

In these technical solutions, the problem that NaCl (salt) itself is also distilled out at this temperature is ignored, resulting in large energy consumption, long production cycle, and high requirements f
