Abstract
Disclosed is a ultra fine egg shell powder preparation method, wherein the process for preparation comprises the steps of, (1) drying clean eggshells, disintegrating the eggshells in high-speed crushing machine, obtaining eggshell powder with grain size of 150-250 meshes, (2) ball grinding the obtained eggshells in a ball grinder.
Description
Technical field: the preparation method that the present invention relates to a kind of ultra tiny egg-shell meal.
Background technology: along with the development of China's aviculture and food industry, a large amount of Ovum crusta Gallus domesticuss go out of use, the disposal of discarded eggshell is a great problem of environmental protection always, if depleted eggshell can be collected, fully utilize, resource utilization and economic benefit can not only be improved, and pollution can be avoided again environmental ecology.The main component of eggshell is a calcium carbonate, is a kind of good calcium source, and also contains the trace element of some needed by human and effective aminoacid etc., it can be carried out processing and utilization to produce various calcium preparation, and not have the preparation method of this respect at present.Micronizing generally is meant the material particles about 3mm is crushed to process below 10～25 μ m, because particulate miniaturization causes the increase of surface area and porosity, ultrafine powder has unique physical and chemical performance, therefore is subjected to the attention of all trades and professions.
Summary of the invention: the objective of the invention is to utilize and discard the preparation method that eggshell is produced ultra tiny egg-shell meal, its preparation process is: a. at first with clean eggshell oven dry, puts into high speed disintegrator eggshell is pulverized, and getting particle diameter is 150～250 purpose egg-shell meals; B. then the gained egg-shell meal is placed ball mill, make the weight ratio of ball material be (5～10): 1, the quantitative proportion that the ball mill grinding medium is used large, medium and small ball with is (1～4): (2～4): (1～4), drum's speed of rotation is controlled at 250～400r/min, and can obtain mean diameter behind the ball milling is the ultra tiny egg-shell meal of 0.1～20 μ m.Eggshell accounts for 10% of egg size, the surface of every eggshell has 10,000 suckings approximately, in preparation process, a large amount of holes helps forming the micropowder sprills, and the eggshell micro-calcium has better calcium absorptivity than general calcium source, existing a large amount of discarded eggshell resource, with its preparation eggshell micropowder, not only develop a kind of novel calcium source, can avoid pollution again, good economic benefit is arranged environmental ecology.Ultra tiny egg-shell meal can be used for the Creta Preparata of food such as cake, beverage, infant food, bread, noodles, milk product, breaded fish stick, sausage, also can be used in the fried food, it has the effect that suppresses the frying oils oxidation, joins the crisp sense of product is increased; Also can be used as the sclerosing agent of brewing water, the deacidification agent of wine, the nertralizer of maltose; In addition, ultra tiny egg-shell meal is being made the too high acidity that is used for reducing fruit juice when Fructus Vitis viniferae spills, it is added in the animal feed, can increase the calcium content of feedstuff, except that above-mentioned, add egg-shell meal to covering abnormal smells from the patient, Lacquer finish, preventing caking and solidify etc. that positive effect is all arranged in food, prepare egg-shell meal with this patent method, the 1Kg egg-shell meal can be produced the eggshell micropowder about 0.76Kg.
The specific embodiment one: the process that present embodiment prepares ultra tiny egg-shell meal is: a. at first cleans eggshell, sterilization, carry out shell membrane separate clean eggshell, with clean eggshell oven dry, put into high speed disintegrator eggshell is pulverized then, getting particle diameter is 150～250 purpose egg-shell meals; B. then the gained egg-shell meal is placed ball mill, make the weight ratio of ball material be (5～10): 1, the quantitative proportion that the ball mill grinding medium is used large, medium and small ball with is (1～4): (2～4): (1～4), drum's speed of rotation is controlled at 250～400r/min, and can obtain mean diameter behind the ball milling is the ultra tiny egg-shell meal of 0.1～20 μ m.
The specific embodiment two: in the present embodiment, with the 50g granularity is that 150～250 purpose egg-shell meals place ball mill, make the weight ratio of ball material be (5～10): 1, the quantitative proportion that the ball mill grinding medium is used large, medium and small ball with is (1～4): (2～4): (1～4), drum's speed of rotation is controlled at 250～400r/min, can obtain mean diameter after 12～18 minutes is the ultra tiny egg-shell meal of 2 μ m, and productive rate can reach 75～90%.
With the inventive method products obtained therefrom index be: the sense organ shape: white powder, preservation stable in the air is dissolved in acetic acid, diluted acids such as hydrochloric acid.Calcium carbonate content is about 92%, and calcium content is about 37.2%, moisture 2.0%, pH value=8.0～9.0.
