FLOATING LID STAINLESS STEEL TANK

:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

REGISTRED MODELS AND PATENTES

1975"LAUNCH OF THE FIRST FLOATING LID TANK"

:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

PRINCIPLE :
- Stainless steel floater with double lip air chamber on raised rim.

USE : 
- Adaptable level of wine storage.
- Fitted with standard heat exchangers (rings) for red ferment or fully-covered for maceration, or insulated (double wall tanks with dimple jacket). 
- Variant : perforated floater for skin dumping, agitator for cold stabilization.

ADVANTAGES:
- Quality and reliability of wine storage enhanced by a rigorous manufacturing conception.
- Handling and maintenance eased by innovative accessories.

CYLINDRICAL TANK

1975 "T.I.G CIRCULAR WELDING ROBOT".

1992 "HEAT EXCHANGER RINGS WITH SPIRAL COILING".

1995 "RESEARCH AND DEVELOPMENT OF IDEALLY PROPORTIONED TANKS".

::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

CONCEPTION :
- Flat inclined at 4% or conical bottom on trapezoidal/octogonal/truncated legs.
- Heat exchangers : rings or dimple jacket for a full-coverage effect, insulated or simple temperature control.

USE :
- Storage, ferment, cold maceration, skin contact, racking.

TRUNCATED TANK

PATENTS AND REGISTERED MODELS

1994 "TRUNCATED TANK"

:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

Lejeune developed a unique technicality with the launch of the first truncated stainless steel tank :
Continuous coiling of the heat exchangers which section remains parallel to the coniticy of the tank.

CONCEPTION :
- Flat inclined at 4% or conical bottom on trapezoidal/octogonal/truncated legs.
- Heat exchanger:s rings or dimple jacket for a full-coverage effect, insulated or simple temperature control.

USE : 
- Storage, ferment, cold maceration.

ADVANTAGES : 
- Reduction of backpressures during cap punching.
- The cap is decompressed by racking and return.

TRUNCATED INVERTED TANK

::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

PATENTS AND REGISTERED MODELS

2006 "LAUNCH OF THE FIRST TRUNCATED INVERTED TANK A.K.A "EXPANSION".

:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

CONCEPTION :
- 80° conicity
- Flat inclined bottom at 4% on trapezoidal/octogonal/truncated legs,
- Without legs and a with crescent base,
- Suspended by the ceiling.
- Heat exchangers : dimple jacket for a full-coverage effect, insulated or for simple temperature control.

USE :
- Storage, ferment, cold maceration.

ADVANTAGES :
- The cap is more permeable and flexible in between pump overs. 
- Gentle dynamic extraction by pinching and compression of the paste.
- More free-run juice released.

COMPARTMENTALIZED TANKS

:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

PRINCIPLE : 
- Cylindrical or truncated tanks with one or various compartments, stacked or partitioned.

CONCEPTION :
- Thermic and structural section of the compartments by a double-bottom.
- Heat exchangers: rings or dimple jackets for a full-coverage effect, insulated or for simple temperature control.
- 1997 "Creation of a "bowl" at the top end of the lower compartment.

USE:
- Storage, white/rosé ferment.
- Variant : both higher and lower compartments equiped for red ferment.

ADVANTAGES :
- Saves space
- Racking, clarification, and running off by gravity.

PATENTS AND REGISTERED MODELS

2002 "INSULATED RECTANGULAR TANK".

2006 "SEMI-SLOTTED TANK FITTED WITH HEAT EXCHANGERS".

::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

CONCEPTION :
- Flat inclined bottom at 4% on trapezoidal, octogonal, truncated legs,
- Heat exchangers: rings or dimple jackets.

USE :
- Recommended for storage.

ADVANTAGE :
- Saves space.

TRANSFER TANK

:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

CONCEPTION :
- Generally cylindrical but can also be truncated or rectangular.
- Volume from 2 to 10hl fitted or not with heat exchangers.

PROS :
- Broad range of shapes so as to adapt to each winery's process.
- Transportable, stackable, can be lifted by elevator or leafting beam.
