A kind of air energy spray drying equipment

Abstract

The invention relates to air energy spraying and drying equipment. The air energy spraying and drying equipment mainly consists of a dryer main tower body, a slurry pump, a tower top hot air distributor, a sprayer, a cyclone separator, an electrostatic separator, a gas and water separator, an air filter, an air delivery fan, a ceramic heater, a high-temperature heat pump compressor, a condenser, an evaporator, an automatic control system and the like. The air energy spraying and drying equipment has the advantages that the exhaust of hot air is avoided in the whole production process, the heat energy of air can be recycled and reutilized, and the energy-saving and environment-friendly effects are realized; the whole production process from inputting raw materials to outputting of finished products (powder) is performed in a sealed system, so that the pollution to foods by air is reduced, and the safety of foods is guaranteed; the separated water can be recycled, so that the loss of vitamin nutrients is reduced; the air energy spraying and drying equipment is mainly suitable for producing foods and health-care products, such as spraying and drying processing of infant rice flour, soybean products, milk products and pastes; the use method is simple, the implementing is easy, and the air energy spraying and drying equipment is suitable for scaled production.

Description

technical field [0001] The invention belongs to the technical field of food production, health care products, instant nutritional rice noodles, etc., and specifically relates to an air energy spray drying equipment. Background technique [0002] Traditional spray drying equipment consumes a lot of energy, and the hot air cannot be recycled and discharged directly, resulting in high loss and high energy consumption. Other food processing equipment also has the same problem. Such as roller drying, cooking and drying, roller drying, cooking and drying are heated by steam, which also consumes a lot of energy. [0003] Take the preparation of traditional infant nutrition rice noodles as an example: [0004] (1) There are puffing drying methods: dry production process of rice crushing, dry mixing, extrusion spraying, crushing, mixing, and packaging. The products are mainly in powder form. The nutrient content of the ingredients is uneven, and infants and young children are prone...

AI Technical Summary

Problems solved by technology

Due to the serious consumption of heat on the surface of the roller in the roller drying method, heat preservation cannot be carried out during the production process, and the hot air and water vapor are directly discharged into the atmosphere and cannot be recycled. A large amount of energy is wasted.

The above two production methods also seriously consume the active ingredients of various vitamins through high-temperature cooking, and the products pollute the production environment and production conditions do not meet international hygiene requirements, and the microorganisms are not easy to control.
