TECHNICAL FEATURES CARACTÉRISTIQUES TECHNIQUES CARACTERISTICAS TÉCNICAS SAFETY SYSTEMS Pressing cycles are managed by me-chanical and automatic safety devices integrated and interfacing with PLCs that manage and control the presses, including a safety circuit with an emergency stop button, and control of the safety cables and side hatches. TANK The tank is delivered either closed with patented circumferential grids or open with a drum perforated all around its circumference. Both are equipped with shaped slots arranged vertically to avoid damaging the grape skins (which leads to the formation...

ELECTRIC CONTROL PANEL All the presses are complete with stainless steel electric control panels with Telemecanique color graphics touch screen and PLC for the automatic and manual control of the pressing cycles and other systems (rotation – blower or compressor/s – product emptying pump – washing pump – marc conveyor belt – inverter-controlled drum rotation on inert gas version - pump on inert gas tank). The manufacturer provides electric devices certified for the main international markets, and available as spares for keeping in stock because they have been standardized for use in all the Della...

LOADING/UNLOADING HATCH Della Toffola presses have large loading/ unloading hatches, with pneumatic Controls as a standard feature on the PE-PEC80 and larger models. In the presses with closed tanks, the watertight closing door is fitted with a special inspectable seal. Positioned opposite the loading/unloading hatch, all the presses have an oval hatch to facilitating drum cleaning procedures. FOOD-GRADE PVC MEMBRANE The heat-sealable, food-grade PVC membrane can expand evenly over the whole inside wall of the drum, pressing even minimal quantities of product. Up to the model PE-PEC100 an elastic...

INERT GAS PRESSES In the inert gas version, the pneumatic presses have a special “gradual program” that assures the extraction of 100% of the must with the aid of an inert gas, but with none of the pollution deriving from the commonly-used gas recovery methods. MUST UNLOADING AND TRANSFER The product emerging from the press’s drum, by gravity or through the manifold provided, is drained into a collection tank (atmospheric pressure system) or into a closed tank (inert gas system). The transfer of the product is managed by the automated control systems. MUST SELECTION Della Toffola presses can...

DRAINAGE SYSTEMS To optimize the unloading and transfer of the marc from the pneumatic presses, there are conveyors of belt (in PVC and stainless steel) or worm screw type, designed and sized to suit each customer’s specific needs. SYSTÈMES D’ÉVACUATION Afin d’optimiser le déchargement et le transport des marcs des pressoirs pneumatiques, on a prévu des systèmes d’évacuation à bande (PVC et inox) ou à vis sans fin, étudiés et dimensionnés en fonction des exigences spécifiques du client. SISTEMAS DE EVACUACIÓN Para optimizar la descarga y el alejamiento del orujo de las prensas neumáticas, están...

SUPPORTING FRAMES Stainless and carbon steel supporting frames are designed to suit to each customer’s particular needs and, where necessary, completed with appropriate service gangways and ladders to enable the construction of functional and long-lasting assemblies. HANDLING SYSTEMS Depending on the customer’s needs, press handling systems can be provided on motor-driven wheels and rails, thus completing the manufacturer’s all-round service. CHÂSSIS DE SUPPORT Les châssis de support en acier inox et en fer sont étudiés selon les exigences spécifiques du client. Lorsque cela est nécessaire, ils...
