Abstract: The invention relates to a device integrating crushing, pulping and enzyme deactivation of fruits, comprising a spiral feeder, a crushing cavity and a drive motor. The spiral feeder is disposed above the crushing cavity. The crushing cavity consists of an inner crushing cavity and an outer crushing cavity. The inner crushing cavity is internally provided with crushing blades and a comb-like cylindrical stator. The crushing blades are formed with a plurality of steam outlets. The outer crushing cavity is internally provided with a ring steam pipe. The ring steam pipe is also formed with steam outlets on the lower side. The outer crushing cavity is provided with a discharge hole. The device integrating crushing, pulping and enzyme deactivation of fruits completes enzyme deactivation and pulping at the same time, has a large production capacity and a high efficiency, and can meet requirements of industrial production.

Abstract: The present invention relates to a preparation method of high-quality apple jam. The preparation method integrates crushing, pulping and steam enzyme deactivation, and immediately adopts ultra-fast cooling after pulping and enzyme deactivation. The ultra-fast cooling integrates vacuum cooling and chilled brine conduction cooling. The whole technological process features strict control over parameters, retention of the original color, luster, flavor and nutrients. The present invention includes the following procedures: quality control of raw materials, namely apples, combination of crushing, pulping and steam enzyme deactivation, ultra-fast cooling, filtration, separation, multi-effect low-temperature concentration, formulating, canning, sterilization and fast cooling. The preparation process of the present invention not only greatly reduces the enzymatic browning of the polyphenol oxidase, but also effectively avoids losses of its flavor and nutrients such as sugar, proteins, mineral substances and etc.
