Dehumidifier selection

Currently softgel drying technology are the following: ① tumble drying, ② ③ static crawler drying tray drying. Because the static tray drying technology has to ensure soft capsule surface gloss, no breakage, etc., after four or five years of practical experience relatively static tray drying technology is a trend. Only because the material drying air temperature, humidity, wind speed, its volatilization of the four relevant elements. As the soft capsules own factors, drying temperature is not too high, so in order to improve production efficiency, it had to reduce the air humidity, the drying chamber increases the number of ventilators aspects to find solutions.

To ensure the soft capsule drying chamber temperature, humidity, cleanliness, large number of ventilators, and in accordance with the GMP standard, we must create an artificial environment to meet the requirements of more than four parameters. Current domestic manufacturers of clean air in the drying chamber to ensure temperature, Character LCD Modules cleanliness, a large quantity of air without any problems, difficulty lies in humidity control in this regard. The humidity at 50 to 70%, in the summer air conditioning alone can solve, and soft capsules the best drying humidity is 20 to 30%, generally air-conditioning and compression refrigeration dehumidifier (belonging to the physical and mechanical dehumidification France) simply can not achieve this humidity requirements, to meet this requirement will have to rely on chemical desiccant. Now widely used chemical desiccant is lithium chloride / silica / zeolite dehumidifier. Since lithium chloride is highly corrosive, easily soluble in water, life is short and other shortcomings in foreign countries has been eliminated; while the domestic is now in a variety of reasons, some units are still used. Silicone (SilicaGel) Traditional Chinese word for the silicone, silicon chemical element silicon words of the old name instead of some manufacturers in the alleged sale of its unique, unique silicone. Silica gel desiccant wheel development in the country tends to be slow, has not yet mature, easy to fall off, moisture absorbent fiber paper is coated on the surface of the efficiency of its moisture is less than 20% of mature products internationally.OLED modules  Silicone runner mature products imported into the wind parameters in ensuring the premise of 27-30 ℃, the unit volume of 6g/kg dry air dehumidification or so, and made only 2g/kg dry air dehumidification unit below. Molecular sieve desiccant wheel is suitable for air humidity usually requires a very low 1% -10% of occasions, such as cell phone lithium battery manufacturing, specialty plastics industries. Since molecular sieve desiccant wheel regeneration temperature is generally above 160 ℃, high energy consumption, high prices, so pharmaceutical companies in general should not be used.
