Device for manufacturing pectin semi-finished product by adopting dry ice method

Abstract

The invention relates to the field of pectin, in particular to a device for manufacturing a pectin semi-finished product by adopting a dry ice method. The technical problem to be solved by the invention is to provide the device for manufacturing the pectin semi-finished product by adopting the dry ice method. According to the technical scheme, the device for manufacturing the pectin semi-finished product by adopting the dry ice method comprises a feeding unit, a dry ice method cracking unit and a centrifugal secondary filtering unit, wherein the feeding unit is connected with the dry ice method cracking unit; and the dry ice method cracking unit is connected with the centrifugal secondary filtering unit. According to the method, the dry ice and the fruit peels are mixed and stacked, so that the pectin in the cells can be completely extracted in a manner that ice cubes break cell membranes due to the fact that the temperature of the fruit peel cells is reduced, moisture in the cells is frozen and the volume is increased; and the fibrous substances in the pectin can be separated after the fruit peel scraps in the filtrate are separated in a secondary filtering manner.

Description

technical field [0001] The invention relates to the field of pectin, in particular to a device for making pectin semi-finished products by dry ice method. Background technique [0002] Natural pectin widely exists in the fruits, roots, stems, and leaves of plants, and is an important part of plant cell walls. Pectin and cellulose are used as filling materials for intercellular spaces and make adjacent cell tissues bond together. Form a stable plant physiological structure, and the application of pectin in food additives is also very extensive. It can be added to various foods other than fruit and vegetable juices as an emulsifier and thickener, and it is also indispensable in the production of jam and jelly Therefore, with the rapid development of the food industry, while pectin is recognized by people, the demand for pectin is also increasing rapidly. [0003] At present, the extraction process of pectin is generally in the pretreatment of raw materials, and then through t...

AI Technical Summary

Problems solved by technology

[0003] At present, the extraction process of pectin is generally in the pretreatment of raw materials, and then through the steps of extraction, decolorization, concentration and drying to complete the acquisition of pectin, but because the peel will be separated from the pulp, the pectin treatment is not enough In time, pectinase will be produced in the peel, and pectinase will hydrolyze the pectin in the peel, so that the yield of pectin will be greatly reduced, and it takes a long time for the peel to be extracted by acidic solution after pretreatment. It takes a long time to extract the pectin in the peel. At the same time, the semi-finished pectin mixture after extraction will contain plant fibers. The existence of plant fibers will affect the degree of gelatinization of the final pectin product and seriously affect the production efficiency of the factory.
