PROJECT DESCRIPTION

The HOBY 6 series membrane presses adopt the widespread membrane pressing process in a simple, effective and economical way.

A central elastic tubular membrane, inflated with air, compresses the grapes towards the walls of the cylindrical tank which is partially perforated. In this way the must is completely extracted from the fruit.

All work phases are performed by the operator without the use of electricity for the manual version, while for the motorized version the rotation of the tank occurs via a variable speed motor and the work phases with the aid of buttons and electric selectors. Or via PLC (Optional). These phases include loading the grapes, pressing, collecting the must and unloading the marc. An external compressor is required to inflate and deflate the membrane (Optional).

 

The HOBY 6 series presses are also available in the OPEN version with a fully drilled tank.

 

HOBY 6 MANUAL

Made of Aisi 304 stainless steel on wheels, with the following characteristics:

 

• Partially perforated tank capacity 4.5 Hl in Aisi 304 stainless steel, PED tested, with treatment

external sandblasting.

• Manually operated tank rotation system, via stainless steel crank with Teflon handle.
• Central elastic tubular membrane in non-toxic food grade rubber with working pressures up to 1 bar, which

are much lower than other pressing systems, thus increasing the quality of the extracted musts.

• Manually opening loading and unloading door positioned centrally, useful dimensions 493×460 mm.
• Sliding must collection tank in Aisi 304 stainless steel with quick coupling and release, outlet connection

Garolla 40 for connection to an external pump. Transparent rod to check the liquid level in the tank.

• Quick compressed air connection for using an external compressor.
• Manometer for detecting working pressures.
• Membrane pressure and vacuum valves.
• Safety valve set at 1.5 bar.
• Stainless steel handle for easy movement.
• Lifting eyes for loading and unloading operations.

  PRESSING APPLES AND POMEGRANATES

   

  The HOBY 6 membrane presses with fully drilled tanks can be used not only for grapes but also for apples, pomegranates and fruit in general.

  It is necessary to send already cut apples or pomegranates to the press, preferably with a shredder that produces a size of 3/8 mm (rather than pulp).

  The load capacity is about 80-90% of the cage capacity with door feeding and stationary cage.

  Yields range from a minimum of 65% to a maximum of 75% depending on the type and ripeness of the apples.

   

  HOBY 6 apple-pomegranate load: 300-375 Kg.

   

  Pressing times vary depending on the quality of the apples/pomegranates:

   

  WITH APPLES: 1 h 30′ – 2 h

  WITH POMEGRANATES: 1 h – 1 h 30′

   

  The indicated performances refer to processing with apples without enzymatic treatment.
