Following processing：Pretreatment, protectiveness roasting, cooling, crushing, activation and dispensing.
S1, pre-treatment step.
In the present embodiment, using oyster shell and zeolite as major ingredient, after oyster shell and zeolite are cleaned with water respectively, by oyster
Shell and zeolite carry out simple crushing, and the zeolite for making the oyster shell after crushing is about original 1/20~1/10.Then remove obvious
The rope of hanging culture on impurity and oyster shell.
S2, protectiveness calcination stepses.
Pretreated oyster shell and zeolite are respectively placed in into progress protectiveness in roasting apparatus to be calcined to obtain roasting material.
When carrying out protectiveness roasting, the parameter of roasting is controlled, it is 600~800 DEG C to make the sintering temperature that protectiveness is calcined, and roasting time is
The flow that 8~12min, oyster shell and zeolite enter roasting apparatus is respectively 0.2~0.4m3/ min, the rotating speed of roasting apparatus are
25~35r/min.
The too high roasting degree to oyster shell and zeolite of sintering temperature has significant effect, and is calcined in oyster shell and zeolite
During, if sintering temperature is too low, oyster shell and zeolite can not thorough roasting, the calcium carbonate in oyster shell and zeolite can not
Calcium oxide is fully converted to, the conversion ratio of product is low.But when the temperature of roasting is too high, calcium carbonate can be fully converted to aoxidize
Calcium, but now the nutritional ingredient of oyster shell and zeolite, micro- poly- pore structure and trace element are destroyed.In the present embodiment, it will roast
Temperature control is burnt at 600~800 DEG C, it can be ensured that oyster shell and zeolite ensure that its nutritional ingredient by thorough roasting.
The overlong time of roasting, also easily make the nutritional ingredient, micro- poly- pore structure and micro- quilt of oyster shell and zeolite
