Principle of concentrator:
The vacuum concentration equipment in the concentrating equipment is one of the main equipment in the production process of the food factory. It uses vacuum evaporation or mechanical separation to achieve material concentration. At present, in order to improve the quality of concentrated products, vacuum concentration is widely used. Generally, in the low pressure state of 18-8 KPa, the material liquid is heated by the indirect heating method, so that it is boiled and evaporated at a low temperature, so that the temperature of the material is low and used for heating. The temperature difference between the steam and the boiling liquid material increases, and under the same heat transfer condition, the evaporation rate is higher than that under normal pressure evaporation, which can reduce the loss of nutrient of the liquid material, and see the use of low pressure steam as the evaporation heat source. The products are mainly adapted to the concentrated production process of traditional Chinese medicine, health care products, natural seasonings, food additives, food, chemical and other industries. It can provide different proportions of extracts for different drying production methods, which is applicable to a wide range of applications, simple operation and low maintenance rate.
