Preparation equipment of chlorophyll metal salt

Abstract

The invention belongs to the technical field of production equipment of chlorophyll metal salt and discloses preparation equipment of chlorophyll metal salt. The preparation equipment of the chlorophyll metal salt comprises a silkworm excrement softening device, a silkworm excrement soaking device, a silkworm excrement soaking liquid concentration device, a chlorophyll liquid concentration device, a chlorophyll paste dissolving device, a chlorophyll saponification device, a chlorophyll metallization device, a chlorophyll acidification device, a chlorophyll salification device and a chlorophyll metal salt drying device which are arranged sequentially. In the process of extracting chlorophyll by using silkworm excrement, acetone and water are recovered respectively under the vacuum environment, so the concentration time is shortened and the concentration efficiency is improved. The process of preparing the chlorophyll metal salt by using the extracted chlorophyll comprises the steps of paste dissolution, saponification, metallization, acidification, salification and the like, wherein the step of separating for many times to remove impurities is also provided, so the impurity content of the obtained chlorophyll metal salt is low.

Description

technical field [0001] The invention belongs to the technical field of chlorophyll metal salt production equipment, and in particular relates to a chlorophyll metal salt production equipment. Background technique [0002] Chlorophyll metal sodium salt is a natural food pigment approved by the Food and Agriculture Organization of the United Nations, the World Health Organization and my country's Food Additives Standards Committee. Chlorophyll widely exists in all green plants. Compared with chlorophyll, sodium chlorophyll metal salt not only has the color tone and strong coloring power of natural green plants, but also has better stability. In addition, sodium chlorophyll salt has its own unique structural characteristics and The nutritional elements chelated in the derivatives have unique advantages in coloring foods that need to be colored and improving or maintaining natural green color, and improving the use value of the food itself. Not only that, chlorophyll metal sodi...
