Why Use a Vacuum Mixer?
Vacuum environments accomplish a variety of mixing goals that vary from one application to another. Void-free mixtures can contribute to the strength and precision of molded composites, for example, or improve the texture and appearance of some gels and pastes.
Vac-U-Spat permits spatulating and investing of inlay, crown, or bridge patterns completely under vacuum. When the investment is mixed and ready, a buzzer sounds.
Homogenization
Vacuum homogenizing is a key process during the manufacturing of many liquid products such as serums, milks, and lotions. It turns a mixture of two mutually insoluble liquids into a state consisting of small particles distributed uniformly throughout the other liquid. While vacuum mixing is not necessary for every type of product, it can greatly speed up production and enhance the quality of the final product. The primary reason is that vacuum eliminates air bubbles more quickly than conventional mixing methods.
In addition, a vacuum mixer’s low drying temperatures help prevent oxidation. The result is a higher quality product with greater stability and shelf life. This is especially important for medical and pharmaceutical ingredients, which must be kept safe from heat.
A vacuum mixer can be used to perform a variety of functions, including emulsification, dispersing, and homogenization. It is ideal for cosmetics, food, and biotechnology applications. Its sanitary construction and easy-to-clean vacuum mixer blades make it a popular choice for the manufacture of creams, ointments, and other liquid cosmetics.
Homogenization is a process that reduces the size of fat globules. This can be done in a vacuum mixer by using high-speed shear and an electric heating tube. It is important to monitor the product as it is homogenized. Ideally, a break valve should be added to the vessel design to stop homogenization when the desired result is achieved.
Dehumidification
Using a vacuum mixer, the process of mixing can be performed in conditions that are free of air and oxygen. This can help reduce oxidation, which can cause degradation of the product over time. It can also help prevent unwanted chemical reactions and microbial growth, which may be a concern in certain processes, especially those where the product will be consumed by humans.
Vacuum environments accomplish a number of other mixing goals, including deagglomeration and deasphalting. These are important for a variety of manufacturing industries, from dental impression materials and plasters to cosmetics and pharmaceuticals. Vacuum environments can also improve the quality of a finished product by reducing oxidation, providing faster processing times and minimizing the risk of contamination.
Choosing a vacuum mixer that is suitable for your specific application will depend on the type of compounds you need to mix, how quickly you need to process them and the safety standards in your plant. Generally speaking, a vacuum mixer can be used to mix silicone, epoxy, PDMS, other polymers, liquids, ingredients and dough. It can even be used to sterilize medical and food equipment.
Impregnation
Vacuum mixing is an important process for powdered active ingredients. These materials are often incorporated into user-friendly dosage forms like chewable tablets, effervescent tablets, oral tablets or capsules. In many cases, air bubbles are created during the process, which can negatively impact the product’s performance mixer manufacturer and quality. The vacuum mixer eliminates these unwanted air bubbles and ensures a thorough homogenization of the product.
A vacuum emulsifying mixer machine can be used in a variety of industries to process products such as latex, gels and slurries. It can also be used in chemical industries to emulsify products such as polyester and synthetic resin paints. It can also be used in the food industry to emulsify sauces and detergents.
Another benefit of using a vacuum mixer is its ability to create an inert environment for the preparation of solid drugs. Atmospheric oxygen can negatively affect the shelf life of these medicines. It is therefore important to inert the preparation of these drugs using a process such as agglomeration or powdered fillers and excipients. This can be done in a vacuum mixer by reducing the atmospheric oxygen content of the mixture.
The vacuum emulsifying mixer is an ideal tool for producing void-free cast solid surface matrix that can be used to make popular kitchen and bath designs. It is designed to evacuate air during the matrix blending process, and its powerful suction is generated by high shear rotation of the blades inside the mixer. This allows it to reduce foaming and air entrapment during the mix, improve dispersal quality, degassing, and increase drying rates at lower temperatures.
Sublimation
Vacuum environments are used for a variety of reasons in manufacturing. In some applications, a void-free mixture is important for aesthetics (like coatings or personal care products), for preserving the strength and precision of molded composites, or for thwarting unwanted chemical reactions and microbial growth. In other cases, a vacuum accelerates drying processes, making it possible to dry heat-sensitive materials without fear of thermal degradation.
Vacuum mixing can also be used to disperse powdered active ingredients in liquids, which is common for drugs that are administered in liquid form. Problems that may occur in this process include undesirable foaming, inhomogeneous distribution of the liquid and solid phases, long process times, and powder agglomeration. In order to overcome these problems, the liquid medium can be pumped through a degassing vacuum mixer to eliminate air bubbles and rapidly cool the medium to sublimate the powdered active ingredient into the gas phase.
To perform sublimation, first place the materials that are to be evaporated into a boat-shaped material carrier in the center of the vertical sublimation purification apparatus. Next, tighten and seal the two end pipes at both ends of the material carrier until the vacuum degree is about 3.2×10-5 mbar, extract air by connecting the pipe at the air extraction end with the vacuum system until the pressure of the system drops to a vacuum level, and then raise the temperature of the heating evaporation device to the condensation point. At a regular time interval, turn on the product scratching device to scrape off the sublimated vapor from the surface of the condensation region and push it downward into the product storage tank 92.
