Vacuum impregnation may be employed for as a technique for the application of edible film and coating, in order to produce functional food using physiologically active raw materials. Production of novel functional food with the application of vacuum impregnation facilitates the introduction of e.g., probiotics, vitamins, biologically active compounds and mineralsto the fruit and vegetable matrix (Table 2). Literature data mainly concern the kinetics of matrix fortification, potential use of certain active compounds, interactions between tissue and the introduced compound as well as the effect of additives on the rate of respiration processes and potential protectionof products against spoilage.

Vacuum impregnation is a non-destructive method of introducing a solution with a specific composition to the porous matrices of fruit and vegetables. Mass transfer in this process is a result of mechanically induced differences in pressure. Vacuum impregnation makes it possible to fill large volumes of intercellular spaces in tissues of fruit and vegetables, thus modifying physico-chemical properties and sensory attributes of products. This method may be used, e.g., to reduce pH and water activity of the product, change its thermal properties, improve texture, color, taste and aroma. Additionally, bioactivecompounds may be introduced together with impregnating solutions, thus improving health-promoting properties of the product or facilitating production of functional food.

Vacuum Pressure Impregnation (VPI) is the process of treating the finished coils with varnish by placing it a vacuum chamber. First, the transformer is placed in an oven and heated to approximately 100 to 125 C. This heat treatment drives out moisture from the insulation which could otherwise compromise the insulation.
After heating, the transformer is placed into the VPI hot. The advantage of doing it this way is that it makes it easier for the varnish to penetrate the insulation to the maximum extent possible since the viscosity of the varnish goes down as it is heated by the coil.
Next, the coil is placed in the vacuum chamber and a vacuum is pulled dryon the transformer. The varnish is then admitted into the chamber and the vacuum is pulled wet Finally, the chamber is pressurized to 100 psi completely filling the coil and insulation with varnish, and then varnish is finally pushed out of the chamber. This results in a coil that is totally saturated with varnish (with atmosphere dip it is only partial). The insulation will then have its maximum dielectric strength and will not absorb moisture (key to longevity). Also, because varnish is a good adhesive, it has better mechanical strength. In addition, because varnish is a good thermal conductor, it runs significantly cooler.
The benefit of VPI on the plate transformer is that it reduces the temperature rise by approximately 20%, making it run appreciably cooler and quieter. And the result of that is greater reliability and extended life. This is recognized throughout the transformer industry and is backed up by numerous studies
We hope this information is helpful to you as you consider your options for your future designs. We believe that your transformers should all be treated with VPI,
Vacuum impregnation is used in many different manufacturing processes to enhance mechanical strength, seal surfaces and to enhance electrical insulation properties. Vacuum Pressure Impregnation (VPI) is the process of treating the finished coils with varnish by placing it a vacuum chamber.
One of the most common application for impregnating
compounds is in electrical transformer manufacturing.
Transformer coils are impregnated for some or all of the following reasons:
Increase the overall dielectric strength
Improve the structural integrity of the coils
Reduce or eliminate winding noise
Improve heat transfer
Reduce partial discharge
Provide increased environmental protection
In addition, varnish / epoxies are excellent adhesives and will solidly bond the wires and other components of the structure to form a strong, solid assembly. As a side benefit, this also reduces noise during operation.
Material Requirements
Impregnating compounds are not designed to provide high build rates. They are designed to penetrate and seal the nooks and crannies of the structure.
The best products have the following features:
Reasonably low viscosity
Reasonably good shelf life
Long working time (pot life)
Good dielectric strength
High vapour pressure
Operating temperature rating to match or exceed the rating for the coil
Moderate cure
