A method for efficiently crushing and separating eggshells and shell membranes of poultry breeding eggs after hatching

Abstract

The invention discloses an efficient crushing and separating method for eggshells and shell membranes obtained by incubation and hatching of hatching eggs of poultry. The efficient crushing and separating method comprises the following step: performing suffumigating, drying, primary crushing, vibration screening, electric windwill separation and the like on a complete eggshell (including inner and outer layers of shell membranes) obtained by incubation and hatching. The method is high in crushing and separating efficiency, and the purity of obtained products, i.e. eggshell powder and shell membrane powder, is 98 percent or above, and the moisture content is less than 8 percent; the obtained products are free of pathogenic bacteria, nontoxic, harmless, pollution-free and safe; furthermore, the natural attributes of the eggshells and shell membranes which are obtained by incubation are retained, and the products meet the feed level standard; and the method is suitable for batch processing of breeding poultry incubation fields of different scales, and the eggshells and the shell membranes can be separately used or combined for use so as to develop the breeding value of the nutrition and the functionality of the eggshells and the shell membranes, improve the productivity of the poultry and the disease resistance of livestock, realize reuse of complete eggshell resources obtained by the incubation and reduce the pollution to the environment.

Description

technical field

[0001] The invention belongs to the technical field of feed raw material processing, and in particular relates to a method for efficiently pulverizing and separating eggshells and shell membranes of poultry breeding eggs after hatching. Background technique

[0002] The poultry breeding industry is the pillar industry of my country's animal husbandry industry, and it is also the industry with the highest degree of scale and intensification, which is close to the international advanced level. There are many types and large quantities of poultry, including chickens, ducks, geese, quails, etc., and the annual slaughtering poultry volume reaches more than 12 billion. With the rapid development of my country's poultry breeding industry, the scale and number of breeding poultry hatcheries have increased sharply, and they are also facing the problem of eggshell treatment after hatching. According to the survey, after hatching eggs in breeding poultry (chicken, duck...

Embodiment 1

[0025] A hatchery A has been hatching and supplying a variety of chicks for many years. The annual emergence is about 3 million chicks, and the eggshells produced after hatching are about 17 tons. Due to the random stacking of eggshells in residential areas, it has caused great environmental pollution. In June 2015, the present invention was used to separate eggshells and shell membranes. The method is as follows:

[0026] a. After picking out the hatching chicks, place the hatching tray with egg shells on the hatching frame, push it into the hatching machine and press formalin (48ml / m 3 ) + potassium permanganate (24g / m 3 ) closed fumigation for 24 hours.

[0027] b. After disinfection, take it out and spread it on the cement floor to dry for one day, or keep it in the hatcher for ventilation, and then use the incubation setting temperature of 40°C to dry for 16 hours.

[0028] c. Utilize the 9ZF-50 chaff crushing and kneading machine (aperture of the sieve bottom: 8.0mm), ...

Embodiment 2

[0032] Certain poultry limited liability company B raises 20,000 sets of laying hens every year, with an annual output of about 30 tons of intact eggshells after hatching. In order to deal with the problem of hatching eggshells and affect normal production. In February 2015, it was recommended to use the eggshell and shell membrane separation method of the present invention, the method is as follows:

[0033] a. After picking out the hatching chicks, place the hatching tray with eggshells on the hatching frame, push it into the special fumigation and disinfection room and press formalin (40ml / m 3 ) + potassium permanganate (20g / m 3 ) closed fumigation for 24 hours.

[0034] b. After disinfection, push the egg rack trolley into the hatcher, and set the temperature for incubation at 50°C to dry for 12 hours.

[0035]c. Pour the eggshells into the ground groove and use the spiral lift to force feed the material into the hammer mill (the aperture of the sieve bottom is 8.0mm). ...

[0039] A certain duck hatchery C raises 10,000 sets of laying ducks all the year round, and the annual eggshell output is about 16 tons. In order to completely change the pollution to the environment caused by eggshell stacking, in August 2015, the eggshell and shell membrane separation method of the present invention was carried out:

[0040] a. After picking out the hatched ducklings, put the hatching tray with eggshells into the airtight disinfection room, press formalin (44ml / m 3 ) + potassium permanganate (22g / m 3 ) closed fumigation for 24 hours.

[0041] b. After disinfection, take it out and spread it on the cement floor to dry for one day, or put it into the hatcher, and set the temperature for 14 hours at 45°C for incubation.

[0042] c. After drying, use a hammer-type feed mill (screen bottom aperture: 8.0mm), pour eggshells from the feed port for primary crushing,

[0043] d. The primary crushed material is vibrated and screened by a multifunctional grain screen...
