The range of bottling machines is further differentiated between machines for wine bottling, machines for beer bottling, machines for milk bottling and specific machines for oil, viscous liquids and other distillates . All electric benchtop models are available both with stainless steel and plastic nozzle, while gravity machines feature all stainless steel nozzles.
The main difference between these two categories of bottling machines lies in their operating systems. The advantage of vacuum electric bottling machines is that they transfer the liquid directly into the bottle, without shaking or reflux, allowing natural filling and preserving the features of all products: meaning that bottling with these electric machines has to take place without the product to come in contact with mechanical moving parts or transfer pumps.
The advantage of manual gravity bottling machines is basically their simple functioning based on communicating vessels: the liquid from the main tank passes through an intermediate tank and then ends up in the bottles, using only the potential energy of the fall. This system allows you to perform bottling operations also without electricity, the only maintenance requested is the one necessary to clean the machine.
