Vacuum System Presses – Gas Technology

The Technology

The first vacuum presses were invented as a patented system in the early 90’s. They were designed to reduce to a minimum the contact between air and the item being pressed. The innovative concept then developed through the years, leading to cutting-edge solutions in terms of environmental compatibility and energy savings. Perhaps the most important aspect though is the ability to work with inert gases, recycling them by means of the aerial storing tank (patented system) for a technique which siprem international has become a worldwide specialist in.

The Difference

With traditional presses, working with gases leads to irresolvable problems for the work method, due to instantaneous flow rates and often  inadequate systems. This leads to the amount of gas blown on the inside being insufficient to cover the actual needs, creating dangerous, uncontrollable mixes of air and gas, with oxygen percentages that are well over the 2% limit set by the protocol, and thus making the work entirely wasted, including from  an economic standpoint.

Green Technology

GREEN LEAVE GREEN PLANETThe last stage in the development of inert gases associated with Vacuum System technology consists of the option to use the carbon dioxide generated by the fermentation processes. The use of this fluid, available in the cellar in unlimited quantities and totally free, allows for a considerable reduction in operating costs and a significantly simplified management process. It also enhances the concept of environmental compatibility and energy savings from the system.

Our Strengths

  • The Vacuum System ensures complete product inertisation, thanks to which dangerous pockets of air in the workplace are completely removed
  • There is no limit to the use of inert gases (nitrogen, CO2, helium, CO2/nitrogen, mixes, etc.)
  • No particular structures are necessary to support the gas container
  • The safety valve eliminates the risk of any overpressure in the gas container
  • The PLC controls the management of gas flows in the various directions, ensuring an efficient system
  • Inside the press, gas is always handled through suction, without the use of thrust devices  that may introduce harmful substances to the grapes (metals, graphite or oil)
  • Gas retrieval from the press to the container takes place before the juice is extracted and never at the same time. This cuts any gas pollution down to the utmost minimum and avoids any excess consumption caused by operation of the must drainage pump.
  • Option to automatically wash and sanitise the container and the relevant piping
  •  Versatile management program that allows you to select:
    1. total press inertisation prior to loading the grapes
    2. blowing the gas in the loading phase during rotation
    3. option to use the gas during the entire pressing process or limited to the initial phases (flower)

Temperature decrease, inertisation, rapid extraction of colouring substances. These are the trends that nowadays are the most popular in the oenological environment. Siprem International has developed and patented a multifunctional system of innovative technological concept to fulfil all the new trends, a plant awarded with the Innovation Challenge prize at the Simei 2015. The machine […]

Used that never last

After 25 years and thousands of tons of grapes passed through it, one of our big boys (360 HL Vacuum System Press) has been overhauled and it’s now ready to work for more and more years. It has just left our warehouse to get to a new customer located overseas. Building strong and reliable machines […]
