Introduction to Vacuum Sugar Soaking Process：

Vacuum sugar infiltration, also known as vacuum sugar extraction, is a process or technology that uses vacuum negative pressure to immerse the processed product in sugar solution. The vacuum sugar soaking technology was discussed by food research institutions and processing enterprises as early as the 1990s, and it was not until recent years that it was applied in production by some food processing enterprises in China, most of which are processing enterprises of preserved fruits, candied fruits, and cold fruits, used in the sugar soaking process. Compared with traditional sugar soaking techniques, vacuum sugar soaking technology has the advantages of fast flavor absorption, uniform sugar soaking, less loss of fruit nutrition, fresh color, good taste, safety and hygiene. However, due to the wide variety and diverse characteristics of food, not all preserved fruit foods are suitable for using this process technology. Therefore, targeted process experiments and parameter exploration are needed for the products. The experiment involves determining technical parameters such as the type, shape, and size of the fruit, soaking time, temperature, and vacuum degree. Sometimes, it takes dozens or even hundreds of experiments to obtain ideal results.

The function of vacuum sugar infusion unit (vacuum sugar infusion unit):

The Hefei Xiaoniu Experimental Vacuum Sugar Soaking Unit is a small multifunctional vacuum impregnation device specially developed and produced by our company for universities, research institutions, and enterprise laboratories. This equipment can be used for vacuum sugar, salt, wine, or other liquid vacuum impregnation of various fruits, nuts, vegetables, Chinese herbal medicines, grain crops, and other products, and has a wide range of versatility. The equipment combines multiple functions such as mixing and preparation of aggregate liquid, heating and insulation, automatic constant temperature control, vacuum negative pressure impregnation, cold or hot impregnation, atmospheric boiling, material liquid circulation filtration, and centralized discharge to meet the different process needs of users. It is mainly used for the development of various food processes, the research and development of new products, or small-scale trial production.

Structure composition of vacuum sugar infusion unit:

The Hefei Xiaoniu experimental vacuum sugar infiltration unit mainly includes several parts: vacuum sugar infiltration tank, sugar dissolution tank, syrup conveying pump, vacuum pump, circulating water tank, material basket, internal pipeline valve system, and electronic control system. The entire device is centrally designed on an integrated platform, with a compact structure, small footprint, easy mobility, simple operation, and stable performance. Users only need to connect to external water and electricity to use it.

Working principle of vacuum sugar infusion unit:

The basic principle of the Hefei Xiaoniu vacuum sugar infiltration unit is to use changes in vacuum pressure to infiltrate the product with sugar solution. Taking the vacuum sugar infiltration of melon and fruit products in the preserved fruit industry as an example, when the external air pressure is low, the air and excess moisture in the flesh will be squeezed out by the pressure. When the external pressure returns to normal, the pulp tissue lacking air can quickly absorb high concentration sugar solution, thus achieving the goal of rapid sugar infiltration of the product.

Ordering instructions for vacuum sugar infusion unit:

The conventional configuration of Hefei Xiaoniu vacuum sugar infiltration unit is relatively complete, and it can also be customized according to the actual usage needs of users. The equipment is made of sanitary grade 304 or 316L high-quality stainless steel and undergoes fine polishing treatment both inside and outside, with no hygiene dead corners and in compliance with GMP; It can be designed and produced in steam heating or electric heating form according to the user's heat source situation; The lid opening device can be manually and quickly opened or automatically opened; Internal components can be optionally selected. Our company can provide on-site guidance for debugging and operation, as well as permanent technical support through telephone and online assistance.
