Winegrowers Supplies  -  Grape Crusher/Destemmers and Destemmer/Crushers


  An article about crushing and destemming.

  Crusher/Destemmers:-
    With these machines you can adjust the gap between the rollers (a couple of nuts have to be undone and the roller slid outwards before re-tightening), if you open up the gap then you have mostly destemming. It all depends how easily the berries come off the stalks, this varies with grape variety and ripeness. If the berries are hard to remove then you will need to tilt the crusher/destemmer (e.g. with a block of wood under the outlet end) so that it takes longer to push the bunches 'uphill'. The stalks fall out at the end, ideally there should be a bin to collect these. Unripe berries are best dispensed with, but it is possible to put stalks back through the machine if you feel there are good berries still on.

     I-1000  Crusher/Destemmer - up to 1000 kilos/hour. Ribbed aluminium crushing rollers, painted metal frame, hopper and paddles, stainless steel cage, £343
A separate stand is available for this model, in painted steel, £136

or  Motor driven:-   Please note that with any motor driven destemmer it is a Health & Safety requirement that the machine is raised sufficiently high above floor level that the operator cannot reach over the top and touch the moving parts.

         I-1500  Crusher/Destemmer - 230 volt motor, stainless steel cage, rubber star-shaped crushing rollers, powder coated steel frame and hopper, also a tall hopper extension which is not shown in the photograph, 620 Euros (£564)          advice for use

   W-1500 Crusher/Destemmer - 230 or 380 volt motor, up to 1500 kilos/hour, all stainless steel cage, frame and hopper (900mm x 500mm), ribbed aluminium crushing rollers, 910 Euros (£827)

  I-1500-SS Crusher/Destemmer - all stainless steel cage, frame and hopper, rubber star-shaped crushing rollers, throughput up to 1500 kilos/hour, 230 or 380 volt motor, 1030 Euros (£936)

With the above destemmers the berries drop down from the bottom of the destemmer, so it must be positioned directly over a press, or over a vat (or large sheet of clean heavy-duty polythene), or over:-

     

a Kiesel stainless steel mohno-pump fitted with a special 600mm x 600mm stainless steel hopper and auger (NW90/NW65 connecting thread) and NW65 thread outlet. For pumping destemmed grapes (or juice/wine, with suitable reducing adaptors) all 380 volt (3-phase):-

SP05 B02 1.0/1.9kWatt, 700/1400 rpm, up to 5000/10000 litres/hour, £1695
SP05 B03 2.2 kWatt, variable speed motor 250-1400 rpm, 1500 to 8000 litres/hour, £2495

SP06 B01 2.2 kWatt, 700 rpm, up to 10000 litres/hour, £2245
SP06 B02 2.4/3.5 kWatt, 700/1400 rpm, up to 10000/20000 litres/hour, £2475
SP06 B03 3.0 kWatt, variable speed motor 160-800 rpm, 2500 to 12000 litres/hour, £3390

Stainless steel hopper and auger, £395
Adaptor NW95(90Maische) to NW65 (for when the hopper is replaced with NW65, for pumping wine), £80
NW65 hose-tail, £60 (plus 65mm tubing to convey the crushed berries into a  press or tank)
With extra connectors the pump can also be used as a normal wine pump:-
  straight adaptor (for inlet) NW65 female to 32-Mainz (or NW32) male, £85
  90° bend adaptor (for outlet) NW65 female to 32-Mainz (or NW32) male, £102
Replacement stators: SP4 £64; SP45 £83; SP5 £109

Note: we have found that this hopper system does not work with milled apples; the small pieces of apple hold the juice, so there is no liquid to assist the flow through the pump.

  Destemmer/Crushers, floor standing, motor driven:-

  I-2000 Destemmer/Crusher - stainless steel, throughput up to 2000 kilos/hour, 230 or 380 volt motor, built-in 'mash-pump', 1425 Euros (£1295)

I-3000 Destemmer/Crusher - stainless steel, throughput up to 3000 kilos/hour, 230 or 380 volt motor, built-in 'mash-pump', 1270mm x 750mm x 1370mm, 1620 Euros (£1472)

    T.E.M. Precisa - Destemmer/Crusher
    
These machines are of the latest design which allows highly accurate grape processing and easy cleaning. The standard version has a stainless steel beater with rubber coated blades.
The rotating destemming cage is made of stainless steel and has rounded, deep-pressed holes.
For delicate grape varieties a special Moplen plastic basket is available @ 510 Euros extra.
Removable rubber crushing rollers 860 Euros extra, must gathering tank 460 Euros extra.
D = 60mm hose connection from the must gathering tank to an external large mohno-pump or impellor pump.

The active rotary basket system, allowing adjustment of the distance of the beater from the basket, makes it possible to customise stalk removal depending on the grape variety being processed.
All models are fitted with speed change drive, the 150 and 200 models are also fitted with basket speed change drive. The beaters are rubber-coated fixed blades on the 50, 70 and 100 and with adjustable rubber blades on the 150 and 200 models. Adjustable blades can be fitted on all models, as an optional feature. The standard basket is made of stainless steel and on request Moplen (for 50, 70 and 100 models), also on request it is possible to have different perforation sizes of the stainless steel basket. The rubber rollers are mobile and adjustable and can be tilted for washing. The external pump to be connected to the machine can be rubber-impeller, piston, peristaltic or eccentric screw (mohno). In the version without tub, a pump with eccentric-screw, elliptic piston or peristaltic hopper is required. The beater, basket and must collection tub are removable for easy cleaning.

As the grape bunches are loaded into the feed hopper, a short auger feeds them into the rotating destemmer drum. By destemming prior to crushing a superior must is obtained. The destemming drum has round countersunk holes; this avoids maceration of the fruit and keeps the grape stems intact.
The rotary destemming paddles offer the winemaker the possibility of adjusting the destemmer axle for the best operation on specific grape varieties. The speed of the grape in-feed auger is adjustable independently of the speed of the destemming paddles. This allows the flow of grapes through the machine to be optimized for each variety.
The Laguna's crushing rollers are mounted under the destemming drum so that stalks are not crushed. The rollers are made of rubber and they have small teeth in order to have a special crushing action. Two calibrated hand wheels on the outside of the machine allow the operator to set the roller spacing to give the desired amount of crushing.
Optionally, for the most careful winemakers, a drum made of plastic can be supplied.
If you don't like using suction pumps, you can use other types of pump equiped with a must gathering hopper, ideally eccentric screw (mohno) pumps: the must gathering tank just slides out.
