In today's modern world, the food and drug industry is one of the most sensitive and vital industries. Maintaining the quality, taste, color and health of food from the production stage to reaching the consumer requires advanced and hygienic equipment. Meanwhile, steel tanks and tankers for transportation and maintenance play the role of the beating heart of factories and production centers. Choosing the right equipment not only guarantees the health of the community, but also prevents heavy financial losses caused by food spoilage. As one of the pioneers of this industry, Aldoz Steel Sablan company has defined new standards in this field by providing the highest quality tanks.

Why are steel tanks the best option for the food industry?

The use of various metals and alloys in industry has a long history, but why has steel (stainless steel) become the undisputed king of the food industry? The answer lies in the unique properties of this alloy. Steel tanks due to their polished and non-porous surface, do not allow bacteria and microorganisms to penetrate into the body of the tank. This issue is very important in washing and sterilizing tanks, which is called the CIP system.

In addition to hygiene, corrosion resistance is another important factor. Many foods such as dairy products, juices and sauces are acidic or alkaline which can corrode common metals. food storage tanks made of steel with appropriate grades are completely resistant to these chemical reactions and do not transfer any taste or smell to food. Aldoz Steel Sablan industrial group, with a detailed understanding of these needs, uses the best imported steel sheets to make its products.

All kinds of steel grades in the construction of tanks and tankers

To make a quality steel tank, it is very important to know the type of alloy. In general, two main grades of steel are used in the food industry:

1. Steel 304 (L/304)

This grade is the most common type of steel in the food industry. 304 steel is used to store food with low corrosion such as water, milk, vegetable oils and most powdered solids. food storage tanks which are responsible for transporting raw milk or drinking water, are usually made of this alloy. In addition to having high resistance, this type of steel has a more affordable price than other grades, and it is welded with the highest precision in Aldose Steel Sablan.

2. Steel 316 (L/316)

When it comes to foods with high acidity (such as lemon juice, vinegar, carbonated drinks) or sensitive pharmaceuticals, 316 steel comes into play. This alloy contains molybdenum, which greatly increases its resistance to severe corrosion and chloride environments. If you intend to buy steel tanks for fermentation processes or long-term storage of salty materials, Aldose Steel Sablan experts recommend using grade 316.

Classification of steel tanks based on body structure

Steel tanks are divided into three main categories based on the needs of the client and the type of process that is to be performed on the food. Each of these categories has its own characteristics:

Single wall steel tanks

They are the simplest and most widely used type of tanks. These tanks are only used for storage and storage of materials that do not need to maintain a certain temperature or the storage time in them is short. Food storage tanks, which are used only to store water or transfer raw materials between two production lines, are usually single-walled. Aldoz Steel Sablan company designs and produces these tanks in different capacities from 500 liters to 100,000 liters.

Double-walled steel tanks (insulated)

In many cases, it is critical to maintain a constant food temperature. For example, raw milk should be kept at a low temperature so that its microbial load does not increase. In this case, double-walled tanks are used. The space between the first and second walls is filled with insulating materials such as stone wool or injected polyurethane foam. This structure acts like a large flask and prevents heat exchange with the outside environment. Aldose Steel Sablan guarantees the best insulation for this type of tanks by using advanced foam injection devices.

Three-walled steel tanks (process tank)

These types of steel tanks are the most complex and are used to perform processing operations such as cooking, pasteurization, rapid cooling or curing. In the middle wall of these tanks, heating fluid (such as steam or hot water) or cooling fluid (such as chiller water) flows. These tanks are usually equipped with powerful mixers to ensure uniform heat transfer. The construction of process tanks requires high technical knowledge, which the engineers of Aldoze Steel Sablan specialize in.

Critical features in the design of food tankers

Transportation of liquid food such as milk, glucose, oil and fruit concentrate requires mobile food storage tanks which are installed on the chassis of a truck or trailer. These tankers must have stricter standards than fixed tanks.

One of the most important features in these tankers is the existence of a baffle inside the tank. When braking or cornering, fluid movement in the tank can throw the truck off balance. Wave breakers restrain this force. Also, the automatic washing system is very important in these tankers. Aldose Steel Sablan products in the transportation sector are equipped with advanced washing systems so that after unloading, the tanker can be prepared for the next loading quickly and with minimal water consumption. Polishing the inner surface of the tanker to prevent food from remaining in the seams is one of the priorities of this company's production line.

The importance of welding and polishing quality in steel tanks

Perhaps at first glance all steel tanks look alike, but the main difference lies in the construction details. The most important part in building a sanitary tank is its welding quality. In Aldose Steel Sablan, all welding is done by argon method (TIG), which is the most accurate and clean welding method for steel.

After welding, the polishing stage begins. Welded points should be polished so that no roughness or microscopic holes remain in them. This process, which is called "food industry de-stressing and polishing", prevents the accumulation of bacteria in the welding seams. A poorly polished tank, even with the best washing systems, will not be thoroughly cleaned and can contaminate the entire food shipment. Paying attention to these subtleties is what distinguishes Aldose Steel Sablan from other competitors.

Auxiliary equipment installed on tanks

A complete steel tank is not just an empty tanker, but a set of accessories that complete its use. Some of these equipments are:

1. Manhole: To visit inside the tank or enter the operator for repairs. These valves must be completely sealed.
2. Agitator and electric motor: To keep food homogenous and prevent settling or two-phase liquids (such as buttermilk or cocoa milk).
3. Washing ball (CIP Ball): A spherical piece that sprays water and detergent with pressure to all internal parts of the tank to eliminate the need for manual washing.
4. Level indicator Gauge): to observe the volume of material inside the tank without opening its lid.
5. Safety and vacuum valve: to prevent the tank from bursting or crumpling due to sudden pressure changes.

All the tanks produced in Aldose Steel Sablan can be equipped with the most advanced European and Asian accessories based on the budget and customer needs.

Various applications of tanks in different food industries

Steel tanks and food storage tanks are used in a wide range of industries:

• Dairy industries: Raw milk receiving tanks, pasteurizer tanks, yogurt and cheese fermentation tanks, whey storage tanks.
• Beverage industries: Syrup making tanks, carbonation (carbonation) tanks, fruit concentrate storage tanks.
• Edible oil industries: Crude oil storage tanks, decolorization and deodorization tanks, Tankers for transporting refined oil.
• Confectionery and chocolate industries: Chocolate melting tanks, glucose and invert syrup storage tanks, which are usually double-walled or triple-walled so that the ingredients stay warm and do not harden.

Aldoz Steel Sablan with brilliant experience in all these areas, has the ability to provide expert advice to choose the best type of tank according to the viscosity and sensitivity of your product.

Factors affecting the price of steel tanks

The price of steel tanks depends on various parameters and a fixed price cannot be set for it. The most important influencing factors are:

• The global price of steel sheet: Since steel is an imported product, currency fluctuations and the global price of nickel have a direct effect on it.
• Sheet thickness: Depending on the volume of the tank and working pressure, the thickness of the body sheet and lenses (tank floor and roof) is calculated. The greater the thickness, the higher the weight and price of the tank.
• Type of steel grade: As mentioned, 316 steel is more expensive than 304 steel.
• Quality of construction and equipment: The use of brand motor gearboxes, precision polishing and standard welding increases production costs but guarantees the life of the tank.
• Tank capacity: Naturally Tanks with higher volume need more material.

Despite the fluctuations of the market, Aldoz Steel Sablan company has always tried to offer the most competitive prices to its customers by maintaining premium quality by managing costs and eliminating middlemen.

Maintaining and increasing the life of tanks

Purchasing steel tanks is a long-term investment. In order to maintain this investment, maintenance principles must be followed. The most important thing is to use the right detergent. Using detergents containing high chlorine can even damage stainless steel (causing pitting). You should also avoid mechanical impacts that scratch the polished surface inside the tank. A regular cleaning program (CIP) and periodic inspection of gaskets and fittings will extend the life of food storage tanks by decades. The experts of Aldoze Steel Sablan provide the necessary training for the correct maintenance to the technical personnel of the factories after installation and operation.
