What kind of filter should I choose for filtering eggs?

Egg wash is an important raw material often used in bakery, pastry and confectionery, etc., and the filtration of egg wash is one of the necessary steps to ensure the quality of the product. The correct filtration method can remove the foreign matter and impurities in the egg wash, and ensure the cleanliness and taste of the food. Therefore, it is especially important to choose the right filter.

First, the foreign matter and impurity in the egg liquid

The foreign matter in the egg liquid includes eggshell, yolk membrane, hair, dust, etc. These foreign matters in the egg liquid will affect the quality and taste of food. The impurities in the egg solution are important for bacterial germs and toxins, which are harmful to human body, if they are not removed, they will have an impact on human health.

Second, the role of filtering egg liquid

1, remove foreign matter and impurities. Filtered egg can remove foreign matter and impurities in the egg, to ensure that the food is clean and hygienic and taste

2, add stability. Filtered egg can remove free albumin, cut down on oxidation, thus adding the stability of the egg.

3、Improve the liquidity. Filtered egg can make the egg more fluid, convenient for processing and use.

Third, the choice of filter standards

1, filtering effect. The role of the filter is to remove foreign matter and impurities in the egg solution, so choose the filter to ensure good filtration effect, can filter out more than 99% of the foreign matter and impurities in the egg solution.

2, filtration speed. Filtering speed must be sufficiently fast, so as to ensure production efficiency

3, filtration precision. The higher the filtration precision of the filter, the cleaner the foreign matter and impurities in the egg will be filtered.

4, material safety. Because the egg liquid is a food raw material, so the choice of filter material must ensure safety and harmless.

Fourth, the common egg filter

1, the filter. Strainer is a common egg filter, it can remove the rough foreign matter and impurities in the egg liquid. The filter is divided into stainless steel mesh, plastic mesh and copper mesh and other materials, choose the material suitable for itself.

2, magnetic filter. Magnetic filter can remove iron and steel and other metal impurities in the egg, to avoid oxidation reaction, so as to ensure the freshness and stability of the egg.

3, folding filter. Folding filter can remove small impurities in the egg. For example, about 1 micron particle size, bacteria and viruses. At the same time, the folding filter has a certain high temperature resistance, can withstand higher egg temperatures.

4. Pressure filter. Pressure filter can remove foreign matter, impurities and colonies in the egg liquid. Pressure filter is divided into mechanical and compression type, suitable for a large number of egg filtration.

Fifth, the steps of egg filtration

1, prepare the filter and filter paper and other tools.

2、Put the egg liquid into the container and stir well.

3, put the filter on top of the container, loaded with filter paper, etc.

4、Pour the egg mixture slowly into the filter.

5、Waiting for the completion of egg filtration, pour the filtered egg liquid into a new container can be used

Precautions

1, the filter needs to be regularly cleaned and disinfected to ensure the filtering effect and health and safety 2, before filtering the egg liquid, the egg liquid should be broken evenly to avoid clogging and other problems 3, filtering the egg liquid, we must pay attention to the health and safety, to avoid cross-contamination.

4, for some special requirements of the food, the need for more stringent filtration of egg liquid at the
