Vacuum dryer low-temperature vacuum

Low temperature belt continuous vacuum dryer is a new type of high-efficiency energy-saving drying equipment developed after repeatedly comparing the advantages and disadvantages of conventional spray drying and freeze drying. In the drying of products in Chinese medicine, western medicine, chemical industry, food, health care products and other industries, spray drying is beneficial to cost, but unfavorable to product solubility. Products that require thermal sensitivity are powerless. Traditional freeze-drying can produce excellent product solubility and high quality, but the yield is too low and the price is expensive. The technical specifications of the low-temperature continuous vacuum dryer are between the two types of equipment mentioned above. It can make the dried product form a porous and loose shape, retain the original material characteristics of the product, and have a good appearance. Because it is vacuum low-temperature drying, it can meet the processing requirements of most heat sensitive materials. The low-temperature continuous vacuum dryer has overcome the technical difficulties of continuous feeding and discharging under vacuum, successfully transforming static drying into dynamic drying. While significantly increasing the production of dry products, it has also comprehensively reduced production costs. Low temperature continuous vacuum dryer is especially suitable for spray drying and drying of high viscosity, high fat, high sugar and other materials that are difficult to solve in vacuum oven. And can maintain the stability and consistency of product batches.

What is the stirring and mixing effect of the spiral belt mixer

The horizontal dual axis spiral belt mixer is used for stirring dry and powdered materials to achieve uniform mixing. During mixing, the material is affected by two opposing rotor movements and undergoes composite motion. The dual axis paddle blades equipped with animal materials rotate clockwise and counterclockwise along the inner wall of the groove, while the material near the axis rotates axially and is pushed inward on both sides. The external screw drives the material near the cylinder wall to rotate axially, pushing it from both sides to the inside, thus forming convective circulation and shear infiltration within the material cylinder. The material can be quickly and evenly mixed in a short period of time. A mixer is a machine that utilizes mechanical force and gravity to evenly mix two or more materials. Applied in the pharmaceutical industry, it can accelerate physical changes, such as adding granular solutes to solvents and accelerating dissolution and mixing through the action of mixing machinery. Common mixers include spiral belt mixers, V-shaped mixers, double spiral cone mixers, high and low speed liquid mixers, planetary power mixers, etc. The working principle of a horizontal dual axis spiral belt mixer: The machine consists of two parts: feeding and mixing. It enters from the feed hopper, and the material is lifted into the mixer through spiral blades, entering the mixing drum for mixing. When the material enters the mixing drum for staggered movement, the mixing effect is good.
