PZ series hydraulic presses

PZ 85 | PZ 78 | PZ 83

Traditional winemaking presses have seen a revival in many companies producing high quality red, passito and fortified wines.

For several years now, hydraulic presses have been requested by new producer countries such as South Africa, Australia, New Zealand, and America.

MORI IMPIANTI ENOLOGICI has decided to revive the old knowledge of the construction of hydraulic presses - in 1962 we were among the first builders of hydraulic motor presses with a reverse pressing system, in which the piston pushed from the underlying part to the cage, bringing the product into contact and under pressure with an upper plate which is part of the frame itself.

Modern hydraulic presses are equipped with a collection tray in AISI 304 stainless steel and a painted steel structure with high mechanical resistance and a specially designed hydraulic piston, capable of reaching pressures of up to 350Atm.

The PZ series includes models with cages ranging from 60 to 80cm in diameter, with nominal load capacities from 2.1 to 4.8 quintals.

The cages are specially designed to have a resistance to stress in proportion to the maximum pressure that can be reached, and are available in: wood with iron hoops, wood with AISI 304 stainless steel hoops and entirely in AISI 304 stainless steel.

They can all be equipped with a double pause-work timer, a double speed hydraulic unit and a thrust plate covered in AISI 304 stainless steel.

The 85, 78 and 83 models, respectively 60, 70 and 80cm in diameter of the cages, are equipped with trolley on wheels to facilitate the loading and unloading of the cage itself, given the greater quantities.

The process of these machines is 'soft' treatment of the fermented marc, which does not involve handling during the various pressing steps, which would lead to undesirable cellular disintegration, i.e. an increase in the quantity of lees present in the pressing wines.

The result is therefore to obtain a very clear 'torchiato' or pressing wine, thanks to the drainage from the marc and the avoidance of mixing, using pressure the system will then expel the fermented skins as well as the dried grapes.

The Vertical Hydraulic Presses returns from history with all the qualities of the ancient winemaking tradition and a modern twist. They are used for the extraction of musts from fermented red grapes and delicate wines from destemmed white grapes.
