Hawach vacuum spray dryer breaks through the technical problem of continuous feeding and discharging under vacuum, and successfully transforms static drying into dynamic drying. While greatly increasing the output of dry products, it also reduces the production cost.
The automatic vacuum low-temperature continuous dryer is especially suitable for spray drying and drying of high-viscosity, high-fat, high-sugar materials that are difficult to solve in a vacuum oven. And can well maintain the stability and consistency of the product batch.
Scope of application of vacuum spray dryer: Suitable for drying more than 200 kinds of food, chemicals, pharmaceuticals, etc. The automatic vacuum spray dryer is a new concept of high efficiency and energy-saving drying equipment.
In the drying of products in traditional Chinese medicine, western medicine, chemical, food, health care products, and other industries, spray drying is beneficial to the cost, but the solubility, original flavor and powder shape of the product have large defects, and it has a slightly higher viscosity and heat sensitivity requirements. The product is even more powerless.
Conventional freeze-drying can obtain excellent product solubility and high-quality products, but the yield is too low and the cost is expensive.
The process indicators of the vacuum spray dryer are just between the above two types of equipment. It can make the dried product become porous and loose, retain the original material properties of the product, and have a good appearance. Because it is vacuum low-temperature drying, it can meet Processing requirements for most heat-sensitive materials.
The advantages of vacuum spray dryer: The entire experimental process of spray drying is completed in a vacuum environment, which greatly reduces the drying temperature of materials and solves the problem of spray drying of heat-sensitive materials. Color touch screen operation: heating temperature PID constant temperature control, peristaltic pump feeding speed can be adjusted at any time.
Built-in imported oil-free air compressor, the particle diameter of the spray powder is normally distributed, the fluidity is very good, and the noise is very low, which meets the national laboratory noise standard; the spray head is a concentric spray head, ensuring that there is no eccentricity during atomization.
As a result, the spray head can be moved up and down after installation to facilitate the adjustment of the atomization position to improve the spray drying effect; the atomization structure of the two-fluid spray is precision manufactured with high-quality stainless steel materials, and the design is compact and does not require auxiliary equipment. Easy to use, as long as new.
In order to meet the user’s requirements for adjusting various parameters in the experimental range, the real-time PID constant temperature control technology is adopted in the design of the drying temperature control, so that the temperature control of the whole temperature zone is accurate, and the heating temperature control accuracy is ±1℃. The feed volume can be adjusted by the feed peristaltic pump, the rated processing volume is 800mL/H.
