Embodiment 1

[0015] Take the by-product of pearl cultivation, the spinosa clam shell, wash it with water, bake it in a high-temperature electric furnace at 1000°C for 1 hour, crush it to 40-50 mesh after cooling, put it into a paper bag, and obtain the desiccant.

Embodiment 2

[0017] Take mussel shells, a by-product of pearl cultivation, wash them with water, bake them in a high-temperature electric furnace at 1200°C for 1 hour, crush them to 40-50 meshes after cooling, and put them into paper bags to obtain the desiccant.

Embodiment 3

[0019] Take the clam shells from the by-products of pearl cultivation, wash them, bake them in a high-temperature electric furnace at 1200°C for 1 hour, crush them to 40-50 meshes after cooling, put them into paper bags, and pack 20g in each bag to obtain the obtained product. The shell desiccant described above. Put this packaged desiccant in the vacuum packaging of certain food, the applicable amount is at least 1 package per 500g of food, less than 500g is counted as 500g. In the case of unchanged food quality, the utility of the desiccant is two years.

Abstract

The invention relates to a desiccant preparation method which uses shells. The method is that the shells are baked at the temperature of 1000 to 1200 DEG C for 1 to 1.5 hours, and the desiccant is obtained after smashing the shells. The invention is characterized in that the invention uses clam shells which are byproducts of pearl cultivation as materials for preparing the desiccant. Discarded shells are processed and reused, thus avoiding waste, solving the environment pollution problem of shells and the problem of limited sources of existing desiccant materials; therefore, the method can serve multiple purposes.

Description

(1) Technical field [0001] The invention relates to the comprehensive utilization of shells which are by-products of pearl cultivation. (2) Background technology [0002] The value of pearls is noble, which has brought great wealth to the people of Shanxiahu. However, the oysters that produced pearls suddenly lost their color after breeding pearls and were abandoned. Except for a small part being utilized, most of them are discarded and cause environmental pollution. In fact, clam shells have high utilization value. If they can be used, they can not only solve the problem of environmental pollution, but also turn them into wealth and form a virtuous circle. [0003] The sources of desiccant raw materials sold in the market today are limited, the processing technology is complicated, and the cost is high. Due to the unknown and complex ingredients in the desiccant, children will have serious side effects if they eat it by mistake. Poisoning incidents caused by unprepared d...
