Background technique

During the production and processing of royal jelly, it is necessary to remove impurities such as bee carcasses, beeswax slag and dust, so it needs to be filtered. The fresh royal jelly is in the form of a syrup, which is semi-fluid, and the impurities present in the royal jelly and the 10-hydroxy-2-decenoic acid (10-HDA) crystals easily clog the filter, so the filtration of the royal jelly is very difficult. Fresh royal jelly is rich in active peptides, hormones, enzymes and other biologically active substances. Its biological activity is unstable, and it is easily damaged under the influence of temperature, light, air, processing and other conditions, especially the temperature affects its health care effect. Therefore, improving filtration efficiency and quality will help reduce the degradation of royal jelly bioactive substances and maintain the quality and freshness of royal jelly.

There are two main methods for filtering the existing royal jelly: First, the royal jelly is filtered by the compressed air of the piston. The filtering device has the advantages of simple structure and convenient operation, but has the following disadvantages: continuous filtration cannot be realized, and the royal jelly raw material needs to be continuously added in the production process; the efficiency in the initial stage of filtration is high, and in the middle and late stages, beeswax residue in the royal jelly, 10-HDA ( Royal jelly acid, crystals, bee corpses and other impurities can easily block the filter, so it is necessary to frequently replace and clean the filter, resulting in reduced production efficiency, more loss of royal jelly, low filtration efficiency; air squeeze filtration in filtration, filtration of royal jelly air Carrying a large amount causes oxidation of some biologically active ingredients. Second, through the mechanical oscillation filter to achieve royal jelly filtration. The mechanical structure of the filtering method is relatively simple and the operation is convenient. However, there are the following disadvantages: the efficiency of the initial stage of filtration is high, and the impurities are greatly blocked due to impurities such as beeswax residue, 10-HDA (parent acid) crystals, and bee corpses in the royal jelly, which greatly reduces the filtration efficiency; Slag mouth, but there is no design equipment to achieve the slag removal function, only by oscillating slag, the slag removal effect is poor, so the operation process also needs manual slag removal or replacement of the oscillating screen to improve the filtration efficiency, it is difficult to achieve efficient continuous Filtration operation; oscillating operation is used in the filtration, and the possibility of contact of the royal jelly with the air is increased during the oscillation process, thereby aggravating the oxidative deterioration of the biological active component of the royal jelly.
