The rose material with 75-80% water content was screened by a sieve machine and then transferred to the cloth bin of the microwave hot-air drying equipment. The material was spread on the conveyor belt and then mixed and dried continuously for 20-25 minutes in the microwave hot-air drying equipment until the moisture content was 20-25%. The material was then transported to the hot-air drying equipment for hot-air drying. During the drying process, the moisture in microwave hot air drying equipment and hot air drying equipment was extracted by dehumidification equipment, and the rose essential oil in the humid air was extracted by cyclone condensation.Rose microwave hot-air bleaching extract process is simple, labor-saving, greatly shorten the process time. The product obtained by microwave hot-air combined drying meets the national standards, color and shape remain unchanged. In the drying process, the extraction of rose essential oil from the moisture generated greatly improves the added value of the product, and is also conducive to the drying of roses. The method for extracting rose by microwave hot air is characterized by the following steps: (1) the rose material with 75-80% moisture content is screened by a sieving machine and directly transmitted to the cloth bin of the microwave hot air drying equipment, and the mechanical cloth is evenly spread on the conveyor belt of the microwave equipment; (2) the rose material after the cloth is conveyed to the microwave heating device; (1) the rose material after the cloth is clothed is conveyed to the microwave heating device. In the air drying equipment, the microwave and hot air are mixed continuously to kill the green and dry, and the material is discharged after fixing the color and shaping, and the temperature of the discharged material is 70-85 degrees centigrade; (3) in the process of continuous mixing and killing the green and dry described in step (2), the moisture in the microwave hot air drying equipment is extracted through the dehumidification equipment, and the essential oil of rose is extracted by condensation recovery; (4) the discharged material is directly fed in step (2). In the hot air drying equipment, the material is discharged with the moisture content less than 10%, and the temperature of the discharged material is 55-65 degrees C. (5) During the hot air drying process described in step (4), the moisture in the hot air drying equipment is extracted by the dehumidifying equipment, and the essential oil of roses is extracted by condensation recovery; (6) The discharged material after the hot air drying is sent to the screening machine for classification. Inspection and encapsulation; encapsulation of rose essential oil extracted from step (3) and step (5) for reserve.
Continuous mesh belt drying equipment has many varieties and complete functions. Among them, the microwave hot air drying equipment series includes single-layer mesh belt type hot air drying equipment, multi-layer mesh belt type hot air drying equipment, single-layer mesh chain type hot air drying equipment, multi-layer mesh chain type hot air drying equipment, multi-layer flip plate type hot air drying equipment, and the belt drying equipment manufacturer delivered to production has a wide range of cases, covering food, medicine, chemical industry, agricultural and sideline products, Chinese medicine processing, building materials. Metallurgy and other industries of national economy.< p> Rose microwave hot-air extraction Cell fluid to enhance added value, provide a variety of drying equipment selection options and quotations. This paper comes from the microwave hot air drying equipment () network.
