Embodiment 1

[0024] A preparation method for making high-quality shell powder from discarded shells, comprising the following steps:

[0025] S1: Material preparation: Prepare waste shell materials, and clean the surface to remove all impurities and dirt attached to the surface;

[0026] S2: Cooking: Take out the cleaned shells, put them into the pot, and add the mixed supernatant to boil, quickly heat the water to 90°C, stir the shells in the pot during the heating process, when the temperature reaches 90°C After ℃, keep the high heat and continue to boil for 0.5h;

[0027] S3: Cold soaking: put the boiled shells into ice water to quickly cool down the high-temperature shells;

[0028] S4: crushing and drying: take out the cold soaked shells, press the shells into small pieces, put the small pieces of shells in a drying oven for baking, the temperature in the oven is kept at 80°C, and the baking time is 1h;

[0029] S5: Crushing: put the crushed and dried shell fragments into a ball mil...

Abstract

The invention relates to the technical field of shell powder preparation, and discloses a preparation method of high-quality shell powder from waste shells, which comprises the following steps: S1, material preparation: preparing a waste shell raw material, cleaning the surface of the waste shell raw material, and completely removing impurities and dirt attached to the surface of the waste shell raw material, S2, decoction: taking out the cleaned shells, putting the taken-out shells into a pot, adding a mixed supernatant, performing decoction, rapidly heating water to 90-100 DEG C along with stirring the shells in the pot, and after the temperature reaches 90-100 DEG C, keeping big fire for continuous decoction for 0.5-1h, S3, cold soaking: putting the boiled shells into ice water, and quickly cooling the high-temperature shells, and S4, crushing and drying: taking out the shells subjected to cold soaking, pressing the shells into small blocks, and putting the small blocks of shells into a drying box for baking. According to the preparation method for preparing the high-quality shell powder from the waste shells, the problem that the currently produced shell powder is relatively low in quality can be solved.

Description

technical field [0001] The invention relates to the field of shell powder preparation, in particular to a preparation method for making high-quality shell powder from discarded shells. Background technique [0002] With the rapid development of my country's shellfish farming and processing industry, a large number of shellfish will be produced every year. Seashells have low added value and have long been regarded as waste and discarded on beaches and roadsides. It has become an urgent environmental problem in coastal areas. The recycling of shell waste is the only way to solve this dilemma. It can not only "turn waste into treasure" and increase the added value of shellfish, but also promote the healthy development of shellfish farming and realize ecological environment, economic benefits and social benefits. A win-win situation for all three. [0003] The main component of discarded shells is calcium carbonate. It naturally contains calcium, phosphorus, iron, magnesium an...
