PROJECT DESCRIPTION

The HOBY 10 series membrane presses adopt the widespread membrane pressing process in a simple, effective and economical way.

An elastic central 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.

The rotation of the tank is done by a variable speed motor, all the work phases are performed by the operator with the help of buttons and electric selectors. Or by PLC (Optional). These phases include loading the grapes, pressing, collecting the must and unloading the marc. An external compressor is needed to inflate and deflate the membrane (Optional).

 

The HOBY 10 series presses are also available in the OPEN version with a fully perforated tank.

 

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

 

  • Partially perforated tank capacity 10 Hl in Aisi 304 stainless steel, PED tested, with treatment

external sandblasting .

– Tank rotation system via variable speed motor.

  • 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.
  • DIN80 connection opposite to the door position, for tank cleaning.
  • Stainless steel handle for easy movement.
  • Lifting eyes for loading and unloading operations.
  • Electrical panel and safety ropes compliant with CE standards.

 

Indicative data varies with different types of grapes:

Whole grape load  800 Kg.

Load of crushed or destemmed grapes  1800 Kg.

Fermented grape load (initial grape)   2500 Kg.

Minimum recommended load (whole or destemmed grapes)400 Kg.

Electric power 0.75 kW – 380V – 50 Hz

Dimensions and weight   2060x1060x h 1600 mm. – 470 Kg.

PRESSING APPLES AND POMEGRANATES

 

The HOBY 10 series membrane presses with fully perforated 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 10 apple-pomegranate load: 630-850 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.
