Stainless steel tanks for wine
Stainless steel tanks for winemaking are essential for wine production. They ensure the quality of the wine by preventing oxidation and maintaining a constant temperature. This allows producers to have a high-quality finished product that is enjoyable for consumers.
Storage plants
Storage tanks are made for volumes ranging from 500lt up to 30,000lt. Depending on the needs, they are insulated and coated in part or completely, thus allowing them to be used outdoors as well. The mechanical internal mirror polishing improves the sanitizing properties of stainless steel. The maintenance of the temperature of the product is controlled by the application of embossed shirts welded to the surface of the tank.
Palletized for handling and process
Palletized vertical and horizontal tanks allow the handling of product batches in perfect safety and hygiene. In fact, they are designed to be emptied with vacuum pumps and prevent contamination and alterations of the product.
Autoclaves
Desla Inox autoclaves are produced according to the customer’s needs. The sizing for pressure / vacuum use is calculated by an external notified body as well as testing by a notified body certified by Accredia. This and the use of the most modern welding techniques allow the placing on the market of safe, versatile and long-lasting products.
Wine makers
Desla Inox wine makers are made according to the customer’s requests and specifications by providing a “turnkey” machine equipped with a general panel with an integrated PLC panel for managing the pumping over and spraying process. On request, it is possible to insert the control of the washing system with cycle recording.
Stainless steel tanks for oil
Stainless steel tanks are used in a variety of food processing applications, from storing raw materials to transporting finished products. Stainless steel tanks are strong and corrosion-resistant, making them ideal for use in the food industry.
Storage silos
Storage tanks are made for volumes ranging from 500lt up to 30,000lt. Depending on the needs, they are insulated and coated in part or completely, thus allowing them to be used outdoors as well. The mechanical internal mirror polishing improves the properties of stainless steel. The maintenance of the product temperature is controlled by the application of embossed shirts welded to the surface of the tank.
Oil mixers
Made on customer’s request in AISI 304 or AISI 316. The tanks are studied and designed for a perfect mixing of the product with “anchor” agitator shafts. Temperature control is guaranteed through the application of embossed jackets on the tank walls which allow a large area of heat exchange with low flow rate of hot water / steam with consequent energy savings.

How do we produce them?
Desla Inox specializes in the design and fabrication of a wide range of equipment for the wine and olive oil industries.
Our team of experts works closely with our clients to understand their needs and produce customized solutions that meet their specific requirements.
We use only the highest quality materials and finishes so that our products can withstand even the most demanding industrial applications.
Used materials
Desla Inox almost entirely uses austenitic chromium-nickel steels with a low carbon content. In the AISI classification they are indicated as 300 series; in particular the AISI 304L and AISI 316 L steels (the designation L indicates “low-carbon”) so as to lengthen the time necessary for the precipitation of chromium carbides such as to allow the execution of welded structures, even of considerable thickness, without precipitations of carbides occurring in the welded areas. Good mechanical characteristics especially at low temperatures (down to -254 ° C). For high or very high temperatures we use stainless steels also called “refractory” see AISI 310S.
The main features that make these materials suitable for use in our product sectors are the following:
Surface compactness without porosity
High resistance to shocks and mechanical stresses
Excellent cleanability of the surface over time, understood as high bacterial removability and low bacterial retentivity
High resistance to sudden thermal variations
High corrosion resistance
Welding procedures
Desla Inox has highly qualified operators with welding qualifications in both TIG and MIG techniques. The company also has an automated welding system designed and custom-made with MIG technology by top welding companies at the national and international level.
TIG stands for “Tungsten Inert Gas” and is a versatile welding technique widely used, especially in the production of stainless steel pipes. It is suitable for welding very thin materials, around 0.4-0.5 mm, with an upper limit of convenience of 5-6mm. The bead obtained has excellent mechanical, analytical and aesthetic qualities.
MIG stands for “Metal Inert Gas” and is a more automated technique that is used for thicker materials, as compared to TIG. The filler material transfer during welding can take place in three basic regimes: “short-arc”, “drop-arc” and “spray arc”. The latest welding generators have evolved with the “PULSED-ARC” regime, which is a combination of the “short-arc” technique and the fusion modalities of the “spray-arc”.
Finishes
The company has two polishing departments within it. The first semi-automated allows the surface treatment of cylindrical sheets and internal and external walls of the tanks; the same machine is also able to work on rounded bottoms of different nature and size both internally and externally. The choice to work exclusively in stainless steels and non-ferrous materials guarantees us the absence of contamination.
The finish by abrasion of a product consists in a succession of steps to remove the surface defects created during processing. These phases are obtained with the use of abrasive means that “erase” the deeper traces present on the surface. A series of cycles with increasingly higher grain sizes allow the following finishes to be achieved:
- Satin
- Scotch-Brite
- Glossy
- Mirror polished through pastes
- Mirror glossy with ceramic based discs
In collaboration with our commercial partners we are able to supply products with a blasted surface on request. Shot peening consists in a “bombardment” of the surface with special spheres obtained with a suitable compound of glass and silica, so as to exclude the possibility of contamination of the treated piece. This technique also causes a surface hardening of the material.
Particular surface finishing technique required above all for the inside of the tanks, consists of a polishing treatment due to a passage of current in an electrolytic solution. The main advantages offered by electro-polishing are:
- Reduction of the surface roughness of the product
- Removal of the surface layer stressed by technological operations
- Elimination of machining burrs
- Increase in corrosion resistance
- Increase of bacterial removability and therefore of the hygienic characteristics of the product
- Removal of any surface contamination
Refrigeration or heating
The application of a heat exchange system totally depends on the type of process the machine is intended for; the choice and sizing must be carefully calculated to ensure its efficiency.
The main types of heat exchange systems applied on our machines are the following:
Perforated and pressed sheet to give life to the “ashlar”, the latter once applied to the wall or to the bottom of the tanks acts as a cavity for the passage of fluids or steam. The main advantage is to be able to cover high squares and therefore increase the heat exchange surface with reduced material impact. Spot welding with MIG technique and perimeter TIG welding allow high resistance to pressure (tested up to 6 bar) and excellent mechanical properties to thermal shocks.
Literally tanks inside the tank consists in building a real cavity by superimposing one tank inside the other. This system allows, above all with the use of steam, to have an extremely homogeneous heat exchange and, where required, a delicate cooking of the product.
The application of an ascending or descending spiral of a stainless steel half-tube on the walls of the tanks is the most suitable technique where rapid heating or sterilization of the product is required. The mechanical and physico-chemical characteristics of the half-pipe allow the passage of saturated steam up to 20 bar of pressure. The system is obviously regulated by the PED regulations.
Insulation materials
The type of tank and therefore of the process for which it is intended determines the choice of the insulating material. Another no less important factor is the place of installation of the tank depending on whether it is outdoors or indoors. For these details or for specific customer needs we are able to offer the following types of insulation:
HIGH DENSITY MINERAL WOOL
Certainly the most used for the large range of sizes, thicknesses and thermal conductivity values
GLASS WOOL
Where mineral wool cannot be used for reasons of space or specific thermal requirements
POLYURETHANE FOAMS
It is blown through special holes inside the steel cavity to ensure that even the most difficult corners are reached
