Description
Technical Field
[0001] The invention relates to the technical field of production of core-filled marshmallows, in particular to a production process of core-filled marshmallows and core material heat-insulating storage equipment. Background Art
[0002] In recent years, as consumers' pursuit of taste and quality in snack foods continues to escalate, filled marshmallows, with their rich textures and unique flavor experience, have seen rapid growth in the global snack food market. According to relevant industry reports, the filled marshmallow market has experienced a compound annual growth rate exceeding 12% over the past five years, making it a key area of innovation and market competition for food companies. The production process involves multiple key steps, including the creation of the outer marshmallow layer, the preparation and filling of the filling, and precise control of parameters such as raw material ratios, temperature control, mixing speed, and forming methods. These steps directly determine product quality and production efficiency, and thus impact a company's market competitiveness. In the industrial production process of stuffed marshmallows, the addition of the gelatin core is a core step in shaping the product's unique taste. However, the manual injection process currently used in the industry has become a key technical bottleneck restricting the development of the industry. From the perspective of production efficiency, manual operation is subject to manpower limitations, and the filling quantity per unit time is limited, which makes it difficult to match the high-speed operation requirements of large-scale production lines, resulting in a serious shortage of production capacity. In terms of product quality control, the amount of core material injected mainly depends on the operator's experience and judgment. There is a lack of a standardized and precise measurement system, resulting in significant differences in the core material content of different batches or even the same batch of products, seriously affecting the product's quality stability and brand reputation. In addition, during manual operation, the gelatin core is exposed to the air for a long time, and the surface is prone to rapid solidification due to water evaporation. Not only does it cause a raw material loss rate of up to 15%-20%, but the hard lumps formed by solidification are mixed into the product, which will also destroy the delicate and dense taste of the core material, greatly reducing the consumer's eating experience. With the continuous increase in market demand for stuffed marshmallows and the continuous improvement of quality requirements, the traditional manual injection process can no longer meet the production needs of the modern food industry. It is urgent to develop a gelatin core filling technology that is efficient, precise and can effectively prevent the solidification of raw materials. Summary of the Invention
