Embodiment Construction

[0019] This animal bone powder preparation technology comprises the following steps (combining figure 1 shown):

[0020] A. Cooking: Wash the animal bones with water and smash them into bone pieces, place the animal bones and clear water in the cooking container 1, and the weight of the animal bones and the clear water in the cooking container 1 are equal. Then carry out steaming, steaming temperature is 120 ℃-140 ℃, preferably temperature is 130 ℃. During the heating process, steam with a pressure of 0.2-0.4 MPa is input into the cooking vessel 1, and the cooking time is 1.5-2.5 hours, and then the liquid product is separated. The preferred pressure value of the steam is 0.25MPa, and the cooking time is preferably 2 hours. In this embodiment, 10 tons of animal bones and clear water are weighed.

[0021] B. Calcination: place the cooked animal bones in the combustion furnace 2 for calcination at a temperature of 980°C-1020°C, and calcine until the weight is 28%-32% of the o...

Abstract

The invention belongs to the technical field of new materials, relates to an animal bone meal preparation process, and solves the technical problems of unreasonable process steps, poor product quality and the like in the prior art. The preparation process comprises the following steps of: A, stewing; B, calcining; and C, crushing. A white powder-like bone meal finished product is obtained by the process steps. Compared with the prior art, the animal bone meal preparation process has the advantages that:1, the process flow is simple and is easy to operate and implement; and the production cost is low; 2, the production environment is clean; the production efficiency is high; the product quality is stable; the hygienic indexes are high; and the application field of the prepared bone meal is wide; 3, the bone meal has high content of calcium, phosphorus and the like, high activity, and is easier to be absorbed when serving as a feed or a food addition material; and 4, because of high-temperature calcination, a bone is easy to crush; the bone meal has good color and luster; and the particle size is fine after being crushed.

Description

technical field [0001] The invention belongs to the technical field of new materials, and relates to the processing of animal bone products, in particular to a preparation process of animal bone powder. Background technique [0002] All kinds of animal bones can be obtained after removing the meat, which is rich in calcium, phosphorus, oil, protein and other ingredients. Animal bones are the by-products of animal husbandry. People don't pay attention to the processing of animal bones, and they are often treated as waste. With the advancement of technology, people began to further process animal bones to obtain bone meal that can be widely used in feed additives, pharmaceuticals, toothpaste manufacturing, ceramic manufacturing and other fields. Due to different processing methods, the obtained bone powder has different ingredients, content and uses. In the prior art, the processing method for bone meal is extensive, and the product quality is not stable, and the quality var...
