Method for preparing bamboo salt through temperature program

Abstract

The invention provides a method for preparing bamboo salt through temperature program, and relates to a preparation method of bamboo salt. The invention aims at providing a method for preparing bamboo salt by adopting a stage temperature program. The preparation method comprises the following steps: mixing raw materials; performing three-stage temperature rise calcining; cooling and crystalizing; and grinding. The method for preparing bamboo salt through temperature program, the loss of mineral substances is few, energy resources and raw materials can be saved, and the product bamboo salt has uniform quality and is high in quality. The method is used in the field of preparation of bamboo salt.

Description

technical field [0001] The invention relates to a preparation method of bamboo salt. Background technique [0002] The traditional bamboo salt production process is very complicated. Generally, three-year-old bamboo in the middle of the year is selected, cut into bamboo tubes, and then filled with sun-dried salt, sealed with loess, put into a calcination kiln, and calcined with pine wood at 810 ° C for about Take it out after 8 hours. At this time, the sun-dried salt in the bamboo tube melts and condenses into a salt column, and then breaks the salt column into a new bamboo tube for the next calcination. After raising the temperature to 1000-1400℃ for calcination, the bamboo salt melts into vermilion liquid and flows out of the calcination kiln, and it is left to cool for 1-2 days. After it is completely cooled and solidified into purple-black crystals, the bamboo salt after nine times of calcination The salt is crushed into powder with a machine, and the bamboo salt with u...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a method for preparing bamboo salt by means of programmed staged heating, so that in the relatively closed calcination preparation process of bamboo salt, the temperature in the bamboo salt preparation can be achieved by uniformly heating up the temperature in stages. The precise controllability and uniformity of heating avoid the damage and loss of active ingredients and minerals in the preparation process of bamboo salt, and also avoid the uneven color and content caused by the use of loess sealing in the traditional preparation process of bamboo salt. The content of sulfur compounds is too high, through a high-temperature calcination process, to achieve the uniformity of the quality of the produced bamboo salt
