Hot air circulation oven technology matures

The hot air circulation oven is an important mechanical equipment in the field of pharmaceutical drying. The material is dried by air convection. The drying effect is uniform and the temperature is completely selected by the user. The hot air circulation oven has good sealing performance, has bactericidal effect, and is more safe for the material, and can achieve the effect of rapid drying, so as to shorten the production cycle, save energy, improve product quality and the like.

At present, the hot air circulation oven technology has entered a relatively mature stage, and its products can also meet the needs of most users. Not only that, some ovens also incorporate current trends and use computer systems to enhance controllability, increase automation requirements, and facilitate staff operations.

It is reported that the scope of application of hot air circulation oven is relatively extensive, mainly used in the pharmaceutical, chemical, food, light industry, heavy industry and other industries materials and products heat curing, drying and dehydration. For example, raw materials, crude drugs, traditional Chinese medicine pieces, granules, granules, bottles of honey pills, etc.

With the popularization of hot air circulating ovens in the pharmaceutical field, some pharmaceutical companies have gradually deepened their equipment development. With the unremitting efforts of many scientific researchers, a number of high-quality products have emerged in the market. For example, some products use steam or electricity as a heat source, and an axial fan heats the air in the heat exchanger in a convection manner. The hot air layer flows through the baking pan and the material for heat transfer. Fresh air enters the oven through the air inlet to be replenished, and then it is discharged from the moisture outlet, constantly replenishing the fresh air, and discharging hot and humid air, so as to maintain proper relative humidity in the oven.
